Authors: AKIL Mustafa , US Ali Enes
Published: July 2022

Çalışmanın amacı, Covid-19 pandemisine bağlı olarak geçen zaman süresince takım ve bireysel olarak düzenli spor yapan yetişkinlerde meydana gelen zorunlu sedanter davranışın egzersize yönelik tutum ve davranışlarını değiştirip değiştirmediğini
belirlemektir. Çalışma kesitsel yöntemle değerlendirildi. Araştırmaya 18-40 yaş arası 1150 sağlıklı yetişkin katıldı. Katılımcıların 547’si (%47,6) kadın, 603’ü (%52,4) erkekti. Yöntem 5 bölüm ve 49 maddeden oluştu. Birinci bölümde
katılımcıların sosyodemografik özellikleri; ikinci bölümde egzersiz değişim aşaması kısa soru formu, üçüncü bölümde egzersiz değişim süreçleri ölçeği, üçüncü bölümde egzersiz öz-etkililik ölçeği, dördüncü bölümde egzersiz karar
verme dengesi ölçeği yer aldı. Çalışma, bilimsel araştırma ve yayın etiği kurulu tarafından onaylandı. Bulgular incelendiğinde katılımcıların spor yapmak için hemen harekete geçme aşamasında olduğu tespit edildi. Egzersiz öz-etkililik
algıları orta derecedeydi. Katılımcılarda egzersiz yapmanın algılanan yararları daha baskındı. Bireysel egzersiz yapanların egzersiz davranış ve değişim süreçleri, öz-etkililik düzeyleri ve karar verme dengeleri takım sporu yapanlara
göre daha yüksekti. Katılımcıların egzersiz değişim aşaması ile egzersiz öz-etkililik düzeyleri arasında, egzersiz değişim aşaması ile egzersiz karar verme dengesi arasında, egzersiz öz-etkililik düzeyleri ile egzersiz karar verme
dengeleri arasında pozitif yönde ilişki bulundu. Egzersiz değişim aşamasındaki durumları ile Egzersiz değişim süreçleri arasında, Egzersiz değişim aşamaları ile deneyimsel süreçler ve davranışsal süreçler arasında pozitif ilişki
vardı. Sonuç olarak kapanmada insanların kendi kendini yeniden değerlendirme fırsatı bulduğunu ve kapanmanın son bulmasıyla egzersizlerini sık sık yapacaklarını göstermektedir. Ancak buna rağmen davranışlarının sık sık değişebildiği
ve insanların egzersiz konusunda yardım edici ilişkilerden kaçındığı belirlendi. Daha sağlıklı sonuçlara ulaşabilmek için farklı yöntemlerin dahil edildiği kapsamlı çalışmalara ihtiyaç duyulmaktadır.
The New Manipulation Strategy Of Global Concerns- Influencer Marketing
Authors: SARIKAYA Büşra Fadim
Published: July 2022

Küreselleşmeyle birlikte gittikçe büyüyen ve dünya pazarına hâkim olan global markaların, Instagram gibi sosyal medya platformlarında ünlenen Influencerları kanaat önderi olarak kullanarak, özellikle Z kuşağı gençleri satın alma alışkanlıkları
bakımında etkilemeyi ve hatta manipüle etmeyi hedeflemektedir. Yeni nesil kanaat önderleri olarak karşımıza çıkan Influencerların özellikle 15-18 yaş arasındaki liseli gençler üzerinde ciddi anlamda etki sahibi oldukları, yapılan
birçok bilimsel araştırmanın sonucunda elde edilmiştir. Bu makale, etkileyici pazarlamanın 15- 18 yaş arasındaki gençlerin karar verme süreçlerindeki etkisini ele almaktadır. Influenceların yoğun olarak pazarladıkları ürünler göz
önünde bulundurulduğunda bu yoğunlaşmanın kozmetik alanında olduğu fark edilmiştir. Konuyu tanıtmak için öncelikle Influencer pazarlaması ve gençlik araştırması terimleri incelenecektir. Ayrıca, Kahneman ve Pierre Bourdieu'nun
teorilerinin yardımıyla karar verme prosedürünün bir analizi yapılacaktır. Influencer pazarlamanın nasıl çalıştığına dair çok az araştırma yapıldığından, bunu açıklığa kavuşturmak için ampirik bir çalışma uygulanacak ve bunun için
gençlerle röportaj yapılacaktır. Bu araştırma, gençlerin internetteki Influencerlar tarafından etkilenip etkilenmedikleri ve satın alma hareketlerini ne denli bu etkilenmeye bağlı olarak biçimlendiklerini tespit etmeye yardımcı
olacaktır. Dolayısıyla ankete katılan gençler 15 yaşına kadar ve 15 yaşından büyük olmak üzere iki gruba ayrılmıştır. Görüşmelerin analizi, etkileyici pazarlamanın gençlerin karar verme süreçlerinde belirli bir etkisi olduğunu
göstermeyi hedeflemektedir. Ancak, 17 yaşına kadar olan gençlerin, 18 yaş ve üzerindeki gençlerden çok daha fazla Influencerlar tarafından etkilendiği kanıtlanmış bir olgudur.

Published: July 2022

Çoğunluğu M.Ö. 2. Bin yılın ikinci yarısına tarihlenen Hurrice belgelerin buluntu yerleri Yukarı Habur Vadisi’nden Akdeniz’e ve Orta Anadolu’ya kadar uzanmaktadır. M.Ö. 3. Bin yıla tarihlenen belgelerin sayısı azdır. Hurrice tabletler
çoğunlukla Suriye ve Türkiye topraklarından elde edilmiştir. Bunun dışında Irak ve Mısır’da (Mitanni Mektubu) az sayıda belge bulunduğu söylenmelidir. Hurrice tabletlerin açığa çıkarıldığı arşivler Larsa (?), Urkeš, Mari, Tuttul,
Nagar, Emar, Ugarit, Akhetaten (Tell el Amarna), Tikunani, Hattuša, Šapinuwa ve Šamuha’dır. Bunlar arasında belge çokluğu nedeniyle Hattuša ve Šapinuwa en önde gelmektedir. Amarna’nın önemi ise en uzun Hurrice tabletin burada bulunmasından
kaynaklanmasıdır. Adı geçen üç arşiv Hurri dilinin anlaşılması açısından da öne çıkmaktadır. Amarna Mektubu, Akadca metinler ile karşılaştırma imkânı vermesi, Hattuša çift dilli belgeleri ve Šapinuwa ise Hurrice’nin sözlük bilgisini
geliştirmesi açısından önemlidir. Belgelerin içeriklerini dini, edebi, idari, tarihi ve okul metinleri olarak sınıflamak mümkündür. Dini metinler en ayrıntılı grubu oluşturmaktadır; bunlar arasında büyü ve arınma ritüelleri, tanrı
listeleri, kehanet metinleri ve bir adak metni yer almaktadır. İdari metinler mektuplardan, bir adet arazi vergilendirme tabletinden ve şahıslara dağıtılacak arpa hisselerinin dökümünden oluşmaktadır. Edebi metinler arasında destanlar,
bilgelik metinleri, bir müzik metni bulunmaktadır. Tarihi metinler için verilebilecek en güzel örnek Kayalıpınar (Sivas)’tan günümüze ulaşan bir askeri sefer kaydıdır. Okul metinleri ise Ugarit’te bulunan sözlüklerdir.

Siyasi reklamlar, siyasi pazarlama kampanyalarının hâlâ en etkili silahlarından biridir. Nitekim hem gelişmekte olan hem de gelişmiş demokrasilerde siyasi kampanyalara harcanan bütçenin miktarı yıldan yıla artmaktadır. Kampanya kaynaklarının
önemli bir kısmı medyaya verilen siyasi içerikli reklamlara ayrılmakta, bunun içinde en yüksek payı televizyon reklamları kapsamaktadır. Dijital dönüşüm, iletişimin her alanını etkilediği gibi siyasal iletişim çalışmalarını da
dönüştürmekte ve reklam kampanyalarına yansımaktadır. Bu çalışmanın odak konusu siyasi iletişim alanındaki dijital dönüşümdür. Bir siyasi pazarlama tekniği olan siyasal reklamcılık uygulamalarını konu alan bu çalışma, propaganda
ve halkla ilişkilerin siyasal reklamcılıktaki ilişkisini vurgulayarak literatürde sınırlı olan siyasal reklam türleri, siyasal reklam araçları, siyasal reklam çeşitleri, siyasal reklam stratejileri konularına katkı yapmayı, Türkiye’de
siyasal reklamcılık tarihi ve güncel mevzuat üzerinden altyapı değerlendirmesi sunarak örnek vaka incelemesiyle siyasi kampanya çalışması üzerinden siyasal reklamcılık örneklerini inceleyerek, bilgi ve veriler ışığında mevcut durumun
değerlendirilmesini amaçlamaktadır. Vaka incelenmesi için siyasal arenada önem arz eden 24 Haziran 2018 Türkiye Cumhurbaşkanlığı ve 27. Dönem Milletvekili Genel Seçim sürecindeki siyasi kampanya uygulamaları arasından şeçilmesi
kararlaştırılmış ve seçimi kazanan partinin siyasi kampanya çalışmasının incelenmesi uygun görülmüştür. Bu çalışmanın sonuçları doğrultusunda Türkiye’de yapılacak siyasal iletişimde geleneksel mecralardan fazla geri çekilmeden
dijitale ağırlık vereceğini, Z kuşağı merkezli çalışmalardan oluşan başarılı siyasal reklam kampanyaları göreceğimizi söyleyebilmek mümkündür. Yeni nesil seçim kampanyaları hakkında ise “Seçimlerin Temel Hükümleri ve Seçmen Kütükleri
Hakkında Kanun” tarafından belirtilen propaganda serbestliği ve süresi bağlamındaki sınırlılıklar göz önünde bulundurulduğunda, siyasal reklam çalışmalarında bütçeye ve milli servete daha az yük teşkil edecek, çevre dostu, mecra
satın almayı gerektirmeyecek, etkileşimi yüksek, geniş kitlelere ulaşma potansiyeli taşıyan, yeni teknoloji entegrasyonlarını destekleyen, mevzuat ile sınırlandırılmamış, etkisi ölçümlenebilecek, bölümlendirme, kişiselleştirmeye
ve gerçek zamanlı editoryal düzenlemeye olanak sağlayan, çoklu mecra ile adaptasyonu yüksek sosyal ağların ve diğer online hizmet sağlayıcıların siyasal iletişimde ağırlıklı olarak tercih edileceğini belirtmek mümkündür.
The Performance-Space Adventure of Minstrels in the Dichotomy of Tradition and Modernity
Authors: AÇAR Yakup
Published: July 2022

Âşıklık geleneğinde mekân, âşığın sadece performansını sergilediği bir alan olarak düşünülmemelidir. Sözlü kültürün icra edildiği âşık mekânlarının oluşmasında; bellek, eş zaman, âşık ve bilinçli dinleyici gibi önemli dinamiklerin
bir arada ve yüz yüze olması gerekir. Bu birliktelik geleneğin yazılı olmayan kurallarındandır. Araştırmanın amacı; gelenekten moderniteye geçiş sürecindeki değişen icra mekân türlerinden ve bu mekânlarda uygulanan icra pratiklerinden
bahsetmek, ayrıca değişen icra mekânlarında uygulanan pratikleri gelenek çerçevesinden değerlendirmektir. Araştırmada belgesel tarama modeli kullanılarak var olan kayıt ve belgeler incelenmiş ve bu yolla çalışmanın kuramsal çerçevesi
ve bulguları elde edilmiştir. Gelişen teknolojiyle beraber toplumun gündem ve sanat ihtiyacının bu olanaklarla karşılandığını gören âşık, dijital çağa ayak uydurarak yeni icra mekânını oluşturmuştur. Radyo ile başlayan serüven
televizyon, sinema ve internet/sosyal medya gibi icra mekânlarıyla devam etmiş, bir yandan da plak, kaset, band kaydı vb. albüm çalışmaları yürütülmüştür. Âşık bu yeni icra mekânlarını; hem kültürü daha çok kişilere ulaştırma,
tanıtma ve kendi reklamını yapma hem de kahvehanelerden elde ettiği gelirden daha fazlasını kazanma gibi iki farklı amaçla kullanmıştır. Sonuç olarak, modernite içerisindeki icra mekânları âşığın hedef kitlesini artırmış ve ülke
genelinde bu kültürü yeniden popüler etme eşiğine getirmiştir. Ancak gelenek içerisinde icra edilen önemli çeşitli türleri (destan, hikaya vb. uzun anlatılar) ve uygulamaları (irticalen söyleme, muamma çözme vb.) modernite icra
mekânlarında icra etmemiş/edememiştir. Çünkü modernite içerisindeki icra mekânlarında süre, eş zamanlılık ve yüz yüze etkileşim bir arada olamamaktadır. Dolayısıyla modernite icra mekânlarında geleneğin kısmen temsil edildiği ve
medyanın şekillendirdiği popüler olma merkezli âşık modelleri ortaya çıkmıştır.

Published: July 2022

Introduction: Knowledge of transverse dentofacial dimensions is crucial for accurate diagnosis and treatment planning. Periodontitis can alter the widths of the arches by causing pathological migration of teeth and the concurrent bone loss can affect the transverse width of the arches. Aim: To compare the transverse dentofacial widths in adults with skeletal class I and class II malocclusions with horizontal growth pattern and with mild to moderate periodontitis using Cone Beam Computed Tomography (CBCT). Materials and Methods: This retrospective observational study was conducted in Department of Orthodontics, Faculty of Dental Sciences, Ramaiah University of Applied Sciences, Bengaluru, Karnataka, India, from January 2019 to January 2021. Total 96 CBCT samples (48 skeletal Class I, 48 skeletal Class II) of patients between age group of 25-35 years, patients having mild to moderate periodontitis based on bone loss seen on CBCT and patients having a horizontal growth pattern with the angle between sella-nasion and mandibular plane less than 320 degrees were included in the study. Transverse dentofacial measurements were made on the coronal plane of the CBCT scans. Data were analysed using Statistical Package for Social Sciences (SPSS) version 20. Chi-square test and Student’s t-test were used to compare age, linear measurements and angular measurements between the skeletal class I and skeletal Class II groups. A p-value of <0.05 was considered statistically significant at 95% class interval. Results: In this study the mean age of patients with skeletal class I and class II was 30.89±3.23 and 30.97±3.28 years, respectively. There were 24 females and 24 males belonging to class I and class II groups, each. There was a statistically significant difference in the mean interjugal width and the antegonial width. The mean interjugal width in skeletal Class I and Class II group was 56.95±5.68 mm and 51.28±5.94 mm respectively (p-value was <0.001). The maxillomandibular difference (p-value=0.002), the mean maxillary buccal alveolar crest width difference (p-value <0.001) and mandibular buccal alveolar crest width difference (p-value <0.001) was also statistically significant. The palatal height in skeletal Class I group (21.77 mm) was significantly higher (p value <0.001) and the mean maxillary palatal alveolar crest width in skeletal Class I (36.47 mm) was lower than in the Class II group (37.97 mm). Conclusion: The dentofacial transverse widths such as the interjugal width, antegonial width, maxillomandibular difference, maxillary buccal alveolar crest width and mandibular buccal alveolar crest width were higher in skeletal Class I groups compared to skeletal Class II groups. The maxillary palatal alveolar crest width was higher in skeletal Class II groups compared to skeletal Class I group.

Introduction: The entire world has been affected by Coronavirus disease 2019 (COVID-19) and experts all over the world are working hard to combat this global pandemic. There is a panic among people with resultant psychosocial consequences. Aim: To evaluate the fear factor of COVID-19 using Fear of COVID-19 Scale (FCV-19S) among two groups of patients, one with dermatological diseases managed with immunomodulators and second with dermatological diseases not requiring immunosuppression and also to counsel both the groups regarding the course of their disease and tailoring their visits to the hospital accordingly. Materials and Methods: This cross-sectional study was conducted from 16th January 2021 to 30th April 2021 in the Outpatient Department (OPD) of Dermatology of a tertiary care centre, Indira Gandhi Medical College, Shimla, Himachal Pradesh, India. Consecutive 52 patients meeting the inclusion criteria, with dermatological diseases requiring long-term immunosuppressive therapy and 49 patients with dermatological diseases or cosmetic concerns not requiring immunosuppressive treatment were enrolled for the study. The obtained data was analysed using Epi Info software version 7.2.4.0. Results: A total number of 101 patients were enrolled in the study with a male to female ratio of 1.7:1. Mean age of patients was 41 years (range 18-71 years). Among them, 52 (51.49%) had chronic diseases with relapsing and remitting course requiring immunomodulator drugs and 49 (48.51%) had either cosmetic concerns or diseases not requiring immunomodulation. Seventeen (16.83%) of the total patients had other co-morbidites like diabetes mellitus, hypertension, chronic kidney disease or cardiac diseases. Out of all the study participants, 3 (2.9%) had severe fear, 16 (15.8%) had moderate fear, 36 (35.6%) had mild fear and 46 (45.5%) had no fear of COVID-19. Conclusion: During this pandemic time, patients need to be counselled regarding the course and management of their diseases and stress factor should also be addressed.
Maria Duas Tranças e o galo chorão da Itaoca
Authors: De Almeida Leonardo Oliveira
Published: July 2022

Uma imagem publicada no jornal fortalezense O Estado, de 1º de abril de 1941, mostra Maria Duas Tranças entre os objetos religiosos apreendidos pelo Departamento de Ordem Política e Social (DOPS), como evidências criminais da prática do catimbó. Com os dedos, Maria aponta para um jornal sobre a mesa. Uma pista sobre os motivos de tal exposição pode ser vista na legenda da imagem: “Separa-se os instrumentos cerimoniais e uma edição da ‘Gazeta’ que falava do galo chorão da Itaoca.” Trata-se da primeira página do jornal Gazeta de Notícias, que falava sobre uma série de “aparições demoníacas” ocorridas dias antes, em um bairro situado a 8km do local onde Maria havia sido presa. Neste artigo, analiso como a imagem em questão produziu conexões entre os dois eventos mencionados e busco trazer contribuições aos estudos sobre as religiões afro-indígenas no Ceará e sobre a publicação de imagens dessas religiões na imprensa.
novo cativeiro?
Authors: Farias Juliana Barreto
Published: July 2022

Nas primeiras décadas do século XIX, acordos bilaterais propostos pela Grã-Bretanha levaram à proibição do comércio de escravizados em diversos territórios do mundo atlântico. Nesses processos, emergiram novas categorias de trabalhadores que, muitas vezes, tinham em comum experiências de trabalho teoricamente livres, mas que, na prática, representavam novas formas de exploração e controle da “mão de obra africana”. Meu objetivo, neste artigo, é examinar as trajetórias desses trabalhadores no Senegal, então possessão colonial francesa na costa ocidental africana, onde o tráfico foi proibido em 1818. Conhecidos ali como engagés à temps, eles incluíam tanto os escravizados recuperados no comércio negreiro ilegal, como aqueles que fossem “resgatados” ou adquiridos fora do Senegal e alforriados depois de um longo “aprendizado da liberdade”, em que deviam trabalhar por um período determinado. Conectando percursos de contratados e contratadores (os engagistes), busco compreender diferentes significados conferidos à escravidão e à liberdade expressos por homens, mulheres e crianças.

Aloneliness predicts relational anger and aggression toward romantic partners
Authors: Swets Julie A. , Cox Cathy R.
Published: July 2022

Aloneliness is the negative psychological state characterized by dissatisfaction with one's lack of solitude, which is connected to well‐being deficits (e.g., depression, stress). From an I3 theory perspective, we expected that aloneliness could predict anger and partner‐directed aggression among persons in romantic relationships, who must, by nature of their partnership, dedicate time to their romantic partners. In Studies 1a and 1b (N = 554), trait aloneliness positively correlated with trait anger, aggression, and violence, but more strongly among persons in relationships (vs. single persons). In Study 2, aloneliness was experimentally primed among 93 undergraduates in relationships. When aloneliness was salient (vs. a control), participants reported higher anger and used more pins in a partner‐representative voodoo doll. These results suggest that solitude is an inhibiting factor against anger and, potentially, the perpetration of partner‐directed aggression. Although subsequent work in this area is needed, we add evidence showing the importance of individual differences in the need for solitude.
Event‐based optimal filter for a networked system with multiplicative and auto/cross‐correlated process and measurement noise
Authors: Roy Avinash Kumar , Kannan Srinivasan
Published: July 2022

This article presents an event triggered based optimal filter for a networked system with multiplicative noise in state and measurement matrices. The process and measurement noise are auto/cross‐correlated, which is described as a moving average process. The network in both sensor to estimator (S‐E) and controller to actuator (C‐A) channel is affected by random sensor delay and packet dropouts. These effects are modeled using two random variables for both the S‐E and C‐A channels. Sensor data are transmitted to the estimator through the S‐E channel using an event‐based mechanism. It depends on a time varying threshold to improve trade‐off between tracking performance and utilization of network bandwidth. The process and measurement noise are two‐step auto/cross‐correlated. A comprehensive augmented stochastic model is developed for the networked system by combining the effects of event triggering, network constraints and noise correlation. The filter is designed using an innovation analysis approach based on orthogonal projection. The solution of the filter is given in terms of a Lyapunov and a Riccati equation. An algorithm is presented for the implementation of developed filter. The stability properties of the proposed optimal filter are analyzed. The effectiveness of the proposed filter is shown in the simulation platform and accumulated mean square error performance is evaluated based on Monte Carlo simulation.

The application of wearable devices is promoting the development toward digitization and intelligence in the field of health. However, the current smart devices centered on human health have disadvantages such as weak perception, high interference degree, and unfriendly interaction. Here, an intelligent health agent based on multifunctional fibers, with the characteristics of autonomy, activeness, intelligence, and perceptibility enabling health services, is proposed. According to the requirements for healthcare in the medical field and daily life, four major aspects driven by intelligent agents, including health monitoring, therapy, protection, and minimally invasive surgery, are summarized from the perspectives of materials science, medicine, and computer science. The function of intelligent health agents is realized through multifunctional fibers as sensing units and artificial intelligence technology as a cognitive engine. The structure, characteristics, and performance of fibers and analysis systems and algorithms are reviewed, while discussing future challenges and opportunities in healthcare and medicine. Finally, based on the above four aspects, future scenarios related to health protection of a person's life are presented. Intelligent health agents will have the potential to accelerate the realization of precision medicine and active health.

Ferroelectric domain walls are quasi‐2D systems that show great promise for the development of nonvolatile memory, memristor technology, and electronic components with ultrasmall feature size. Electric fields, for example, can change the domain wall orientation relative to the spontaneous polarization and switch between resistive and conductive states, controlling the electrical current. Being embedded in a 3D material, however, the domain walls are not perfectly flat and can form networks, which leads to complex physical structures. In this work, the importance of the nanoscale structure for the emergent transport properties is demonstrated, studying electronic conduction in the 3D network of neutral and charged domain walls in ErMnO3. By combining tomographic microscopy techniques and finite element modeling, the contribution of domain walls within the bulk is clarified and the significance of curvature effects for the local conduction is shown down to the nanoscale. The findings provide insights into the propagation of electrical currents in domain wall networks, reveal additional degrees of freedom for their control, and provide quantitative guidelines for the design of domain‐wall‐based technology.
LSPR‐Enhanced Pyro‐Phototronic Effect for UV Detection with an Ag–ZnO Schottky Junction Device
Authors: Huang Jing , Li Qi , Lu Xianmao , Meng Jianping , Li Zhou
Published: July 2022

Sensitive and rapid detection of low‐power density ultraviolet (UV) light is of great significance for various applications such as space exploration, biological analysis, environmental sensors, communications, and imaging. However, the persistent photoconductivity (PPC) of photodetectors, which are based on ZnO, will cause a long decay time and make it difficult to capture weak light signals. In this work, the pyro‐phototronic effect of ZnO is integrated with the localized surface plasmon resonance (LSPR) of Ag nanoparticles (NPs) to enhance the performance of ZnO‐based photodetectors. The self‐powered photodetector is consisted of the ZnO nanowires (ZnO NWs) and Ag NPs, which can detect 325 nm UV light with a power density of 340 nW cm−2 quickly and sensitively. Compared with the photodetector without Ag NPs, the performance is significantly improved. Under the 325 nm UV light with the same power density, the best responsivity, and detectivity are 8.82 × 10−5 A W−1 and 4.9 × 1010 Jones, respectively. And the fast response time is remarkably reduced to 8.72 ms. These results help to understand the performance of LSPR enhanced photodetectors deeply and expand the methods for preparing high‐performance photodetectors.

Multi‐electrode arrays with 3D micropillars allow the recording of electrophysiological signals in vitro with higher precision and signal‐to‐noise ratio than planar arrays. This is the result of the tight interaction between the 3D electrode and the cell membrane. Most 3D electrodes are manufactured on rigid substrates and their integration on flexible substrates is largely unexplored. Here, a straightforward approach is presented for fabricating soft interfaces featuring 3D poly(3,4‐ethylenedioxythiophene)‐poly(styrenesulfonate) (PEDOT:PSS) micropillars on a soft flexible substrate made of polydimethylsiloxane (PDMS). Large‐area isotropic arrays of PEDOT:PSS micropillars with tailored geometric area, surface properties, and electrochemical characteristics are fabricated via a combination of soft‐lithography and electrodeposition. A 60% increase in capacitance is achieved for high density micropillars compared to planar electrodes and this is found to be correlated with the increased electroactive surface area. Furthermore, 3D PEDOT:PSS micropillars support adhesion, growth and differentiation of SH‐SY5Y cells, and influence the direction of neurite outgrowth. Finally, by virtue of their elasticity, soft micropillars act as excellent anchoring loci for elongating neurites, facilitating their bending and twisting around the micropillar, increasing the number of contact points between the cells and the electrode, a key requirement to obtain high performance neural interfaces.
Quasi‐1D ZrS3 as an Anisotropic Nano‐Reflector for Manipulating Light–Matter Interactions

Published: July 2022

2D layered materials with low crystal symmetries exhibit unique anisotropic physical properties. Here the systematic studies on the optical modulation effects of such anisotropic 2D materials to isotropic 2D materials in their stacked van der Waals (vdW) heterostructures are reported. By applying angle‐resolved polarization spectroscopic characterizations on the MoS2/ZrS3 vdW heterostructure, periodic intensity variations of the Raman scattering and photoluminescence (PL) emission modes of monolayer MoS2 are observed, which are closely correlated to the anisotropic optical properties of the underlying ZrS3 layers. Such anisotropic optical modulation effects can be identified with the thickness of ZrS3 reduced to few layers (≈6 nm), and are attributed to the strong birefringence and dichroism effects in ZrS3 that cause reflection difference between its crystal axis, thus modulating the Raman/PL intensities of MoS2 via Fabry–Pérot interference effect. Furthermore, the polarized photocurrent response of the heterostructure is also demonstrated, where its major contribution originates from MoS2. This work develops a new methodology to tune the light–matter interactions and properties of isotropic 2D materials by the combination with anisotropic 2D materials, which substantially broadens the application of low symmetry layered materials in polarization sensitive optoelectronic devices.

Authors: García‐Monzón Irma , Borges‐González Jorge , Martín Tomás
Published: July 2022

The heterogenization of homogeneous catalysts onto a solid support is a step towards a more sustainable chemistry. The recovery and reuse of catalysts is extremely important from a practical, economic and environmental point of view. In this regards, we report a series of polymer‐supported tetrahydropyran‐based hybrid dipeptides that serve as active catalysts for the enantioselective Michael addition of aldehydes to β‐nitrostyrenes. These supported catalysts have been designed considering the optimal anchor position and orientation between the catalyst and the solid support. Additionally, the influence of the linker length on the catalytic efficiency was studied. The catalysts allowed the transformation of a variety of substrates in 76–98% yield and with 94–97% enantiomeric excess. Detailed deactivation studies have provided important information, which allows to increase the useful life of these immobilized catalysts.

Published: July 2022

Tendon injury is one of the most common musculoskeletal disorders, resulting in a significant decrease in the quality of life of patients with tendon injury. With the in‐depth understanding of the anatomical structure and pathological changes that occur during tendon repair, tissue engineering methods using cells and biomaterials are widely studied. However, simulation of the aligned tissue morphology present in natural tendons remains challenging. The design of a well‐aligned scaffold would be appealing to promote better tendon regeneration. Here, a dual‐aligned composite scaffold comprising an outer layer of polycaprolactone/silk fibroin (PCL/SF) copolymer electrospun membrane and an inner layer of tendon extracellular matrix (TECM) loaded with tendon‐derived stem cells (TDSCs) is developed to promote rabbit Achilles tendon repair. As resident, tissue‐specific cells, TDSCs possess stronger tenogenic differentiation abilities. The PCL/SF electrospun membrane with a dense structure provides mechanical support and TECM with a loose porous structure provides bioactive constituents and a microenvironment for tendon repair. As shown here, the engineered scaffold facilitates TDSC proliferation and migration, favors tenogenesis‐associated gene expression, promotes tendon repair with native‐like hierarchically organized collagen fibers, and enhances the mechanical properties, indicating its potential value in the tendon tissue engineering field.

In rotodynamic blood pumps (RBPs) a substantial proportion of input energy is dissipated into the blood. This energy may propel damaging work on blood constituents. To date, the link between this hydraulic energy dissipation and respective hemolytic action in RBPs remains vastly unknown. In this study, computational fluid dynamics is applied to compute the hydraulic energy dissipation at 9 operating conditions in two RBPs (HM3: HeartMate 3; HVAD: HeartWare Ventricular Assist Device). Respective interrelations with hemolytic pump performance are elucidated by comparing these computations with in silico predicted and in vitro measured hemolysis. Despite different pump geometries, hydraulic loss magnitudes, and distributions, global hydraulic energy dissipation shows strong correlation (r > 0.95) to in vitro hemolysis with scaling factors in the same order of magnitude for both devices (φHM3 = 0.599 (mL g) (J 100L)–1; φHVAD = 0.716 (mL g) (J 100L)–1). The analytical description of hydraulic energy dissipation reveals to be a function of shear stresses and exposure time, unmasking its analogy to the power‐law formulation of hemolysis. This hydraulics‐based analysis may denote a step ahead to relate turbomachinery to bioengineering and may provide mechanistic insights into the relation between RBP design, hydraulic properties, and hemolytic performance.
Cross‐Ray Ultrasound Tomography and Photoacoustic Tomography of Cerebral Hemodynamics in Rodents

Published: July 2022

Recent advances in functional ultrasound imaging (fUS) and photoacoustic tomography (PAT) offer powerful tools for studying brain function. Complementing each other, fUS and PAT, respectively, measure the cerebral blood flow (CBF) and hemoglobin concentrations, allowing synergistic characterization of cerebral hemodynamics. Here, cross‐ray ultrasound tomography (CRUST) and its combination with PAT are presented. CRUST employs a virtual point source from a spherically focused ultrasonic transducer (SFUST) to provide widefield excitation at a 4‐kHz pulse repetition frequency. A full‐ring‐shaped ultrasonic transducer array whose imaging plane is orthogonal to the SFUST's acoustic axis receives scattered ultrasonic waves. Superior to conventional fUS, whose sensitivity to blood flow is angle‐dependent and low for perpendicular flow, the crossed transmission and panoramic detection fields of CRUST provide omnidirectional sensitivity to CBF. Using CRUST‐PAT, the CBF, oxygen saturation, and hemoglobin concentration changes of the mouse brain during sensory stimulation are measured, with a field of view of ≈7 mm in diameter, spatial resolution of ≈170 µm, and temporal resolution of 200 Hz. The results demonstrate CRUST‐PAT as a unique tool for studying cerebral hemodynamics.

The drawbacks of current state‐of‐the‐art selective membranes, such as poor barrier properties, high cost, and poor recyclability, limit the large‐scale deployment of electrochemical energy devices such as redox flow batteries (RFBs) and fuel cells. In recent years, cellulosic nanomaterials have been proposed as a low‐cost and green raw material for such membranes, but their performance in RFBs and fuel cells is typically poorer than that of the sulfonated fluoropolymer ionomer membranes such as Nafion. Herein, sulfonated cellulose nanofibrils densely cross‐linked to form a compact sulfonated cellulose membrane with limited swelling and good stability in water are used. The membranes possess low porosity and excellent ionic transport properties. A model aqueous organic redox flow battery (AORFB) with alizarin red S as negolyte and tiron as posolyte is assembled with the sulfonated cellulose membrane. The performance of the nanocellulose‐based battery is superior in terms of cyclability in comparison to that displayed by the battery assembled with commercially available Nafion 115 due to the mitigation of crossover of the redox‐active components. This finding paves the way to new green organic materials for fully sustainable AORFB solutions.
Dense Coding and Quantum Memory Assisted Entropic Uncertainty Relations in a Two‐Qubit State Influenced by Dipole and Symmetric Cross Interactions
Authors: Abd‐Rabbou Mahmoud Youssef , Khalil Eied Mahmoud
Published: July 2022

Optimal dense coding and entropic uncertainty relation of quantum memory (EUR‐QM) of the two‐qubit Heisenberg chain model influenced by atomic dipole and Kaplan–Shekhtman–Entin–Wohlman–Aharony interactions are studied. The temporal evolution of the two functions at the phase decoherence environment with the Werner state as the initial state is discussed. The results imply that the dense coding and EUR‐QM have a contrary relationship, and an increase in the phase decoherence rate reduces the behavior of the two functions. The growth in coupling dipole interaction plays a role in oscillating and increasing the minimum bounds of the dense coding capacity. On the other hand, the effect of a thermal bath on the two functions at finite temperatures is investigated. The coding capacity suffers from sudden death as the temperature increases. The possibility of restraining the sudden death induced by the temperature may be enhanced by increasing the strength of the symmetric cross interaction. As the coupling of dipole increases, the EUR‐QM decreases while the coding capacity rises to its maximum value.

Published: July 2022

A recent article by Anderson and co‐workers challenges our conclusions on the aromaticity of the four oxidation states of a butadyine‐linked six‐porphyrin nanoring, based on the experimental 1H‐NMR data and some recent calculations they have performed using the BLYP35 functional. Here, we show that BLYP35 should be taken with caution and demonstrate that the indirect evidence of a ring current from experimental 1H‐NMR data is not a definite proof of aromaticity.

Published: July 2022

Rather than just focusing on the catalyst itself in the electrocatalytic CO2 reduction reaction (eCO2RR), as previously reviewed elsewhere, we herein extend the discussion to the special topic of the microenvironment around the electrocatalytic center and present a comprehensive overview of recent research progress. We categorize the microenvironment based on the components relevant to electrocatalytic active sites, i.e., the catalyst surface, substrate, co‐reactants, electrolyte, membrane, and reactor. Supported by most of the reported articles, the relevant factors affecting the catalytic performance of eCO2RR are then discussed in detail, and existing challenges and potential solutions are mentioned. Perspectives for the future research on eCO2RR, including the integration of different microenvironment factors, the extension to industrial application by coupling with carbon capture and conversion, and separation of products, are also discussed.

We have quantum chemically investigated how methyl substituents affect the stability of alkyl radicals MemH3−mC⋅ and the corresponding MemH3−mC−X bonds (X = H, CH3, OH; m = 0 – 3) using density functional theory at M06‐2X/TZ2P. The state‐of‐the‐art in physical organic chemistry is that alkyl radicals are stabilized upon an increase in their degree of substitution from methyl<primary<secondary<tertiary, and that this is the underlying cause for the decrease in C−H bond strength along this series. Here, we provide evidence that falsifies this model and show that, on the contrary, the MemH3−mC⋅ radical isdestabilizedwith increasing substitution. The reason that the corresponding C−H bond nevertheless becomes weaker is that substitution destabilizes the sterically more congested MemH3−mC−H molecule even more.
Tridecacyclene Tetraimide: An Easily Reduced Cyclooctatetraene Derivative

Published: July 2022

Tridecacyclene tetraimide, TCTI, an electron‐deficient non‐benzenoid nanocarbon with a C56N4 polycyclic framework was obtained in a concise synthesis. TCTI has a non‐planar structure and forms π‐stacked dimers in the solid state. In solution, it undergoes eight single‐electron reductions, yielding a range of negatively charged states up to an octaanion. Except for the latter species, which has a remarkably large electronic gap, the anions feature extended near‐infrared absorptions, with a particularly strong band at 1692 nm observed for the dianion. A computational analysis of the TCTI anions shows that their stability originates from the combined effects of electron‐deficient imide groups and the local aromaticity of reduced acenaphthylene units. The properties of TCTI make it potentially useful in electrochromic and charge storage applications.

Published: July 2022

Herein, we leverage the Ni‐catalyzed enantioselective reductive dicarbofunctionalization of internal alkenes with alkyl iodides to enable the synthesis of chiral pyrrolidinones bearing vicinal stereogenic centers. The application of newly developed1‐NapQuinim is critical for formation of two contiguous stereocenters in high yield, enantioselectivity, and diastereoselectivity. This catalytic system also improves both the yield and enantioselectivity in the synthesis of α,α‐dialkylated γ‐lactams. Computational studies reveal that the enantiodetermining step proceeds with a carbamoyl‐NiIintermediate that is reduced by the Mn reductant prior to intramolecular migratory insertion. The presence of thet‐butyl group of the Quinim ligand leads to an unfavorable distortion of the substrate in the TS that leads to the minor enantiomer. Calculations also support an improvement in enantioselectivity with1‐NapQuinim compared top‐tolQuinim.

Published: July 2022

Simple access to aryl sulfinates from aryl iodides and bromides is reported using an inexpensive Ni‐electrocatalytic protocol. The reaction exhibits a broad scope, uses stock solution of simple SO2 as sulfur source, and can be scaled up in batch and recycle flow settings. The limitations of this reaction are clearly shown and put into context by benchmarking with state‐of‐the‐art Pd‐based methods.

Published: July 2022

Adsorptive separation is an energy‐efficient technology for the separation of C2 hydrocarbons. However, it remains a critical problem to directly produce high‐purity C2H4 from ternary C2H2/C2H4/C2H6 mixtures by simultaneously trapping C2H2 and C2H6. Herein, we report the one‐step C2H4 purification from the ternary mixture by a metal–organic framework Zn(ad)(int) (ad=adeninate; int=isonicotinate). The material combines dense heterocyclic rings and accessible uncoordinated O atoms as strong binding sites for C2H6 and C2H2. Its spindle‐like cage exhibits an interesting shape matching with the targeted molecules, affording Zn(ad)(int) not only high separation selectivity for C2H6/C2H4 and C2H2/C2H4, but also excellent gas capacity. Breakthrough experiments show that polymer‐grade C2H4 can be separated from the ternary mixtures with a record productivity of 1.43 mmol g−1. In situ powder X‐ray diffraction and Fourier transform infrared spectrum analyses further provide deep insights into the separation mechanism.
Thermoelectric Zintl Compound In1−xGaxTe: Pure Acoustic Phonon Scattering and Dopant‐Induced Deformation Potential Reduction and Lattice Shrink
Authors: Li Fan , Liu Xin , Ma Ni , Chen Ling , Wu Li‐Ming
Published: July 2022

We report a Zintl phase thermoelectric material, coarse grain‐In0.99Ga0.01Te, achieving a ZT peak of 1.2 at 648 K and an average ZT=0.8 in 300–650 K, which outperforms all the known InTe‐based materials to date. The synergistic optimization of electronic property and phonon transport are achieved by the purification of grain boundary scattering, together with the Ga‐doping‐induced weak phonon‐electron coupling, which enhances the carrier mobility and carrier concentration simultaneously and consequently gives a remarkably increased power factor of 8.9 μW cm−1 K−2. The DFT phonon calculations indicate the dopant reduces the deformation potential coefficient and induces the lattice shrink, which reduces significantly the acoustic cutoff frequency, and enhances the scattering phase space. Moreover, the bonding hierarchy leads to the dense intragranular dislocation arrays, which suppresses the lattice thermal conductivity further and induces an ultralow lattice thermal conductivity (0.21 Wm−1 K−1).
