Authors: Dat Nguyen Minh , Dai Nguyen Quang , Ngoc Pham Bich
Published: June 2022

All the organizations are striving for the high financial performance that could influence by many factors and attained the attention of regulators and recent studies. Thus, the present study examined the impact of corporate social responsibilities (CSR), entrepreneurship and financial factors such as leverage and liquidity along with firm size on the financial performance of the banks in ASEAN countries. This study has adopted the quantitative methods for the collecting data and gathered the published secondary data from the statements. The data has been extracted from the financial statements and published CSR reports of the banks in ASEAN countries from 2015 to 2020. The ongoing study has executed the robust standard error and fixed effect model (FEM) to examine the relationships among the variables. The results indicated that CSR, entrepreneurship, leverage, liquidity and firm size have significant and positive nexus with financial performance of the banks in ASEAN countries. These outcomes have provided the guidelines to the regulators of the banks that they should focus on CSR and entrepreneurship that could increase the financial performance of the banks.

Immanuel Kant's transcendental deduction of the concepts of pure understanding is not only at the center of the "Critique of Pure Reason", but it is perhaps one of the most important texts of transcendental philosophy. Anyone who wants to deal with it needs to study and understand Kant's deductions in both editions of the "Critique of Pure Reason." In his new book, Alexander Schnell devotes himself to the task of mastering the difficulties of the Kantian texts, focusing on a precise explanation of the basic idea of category deduction. In doing so, the author approaches the subject not exclusively from the perspective of a text-immanent interpretation, but also from a decidedly phenomenological point of view that allows Kant's thought to be connected with contemporary phenomenology. By bringing into play both Martin Heidegger's and Eugen Fink's interpretations of Kant, he thus succeeds in combining intensive immersion in the Kantian text with a commanding outline of the thing itself which is being interpreted.

Published: June 2022

We report here a 7-year girl with B-Acute Lymphoblastic Leukemia (ALL) on Berlin Frankfurt Munster (BFM) based induction chemotherapy who presented with fever, cough, and painful necrotic skin lesions simulating pseudomonas sepsis. The patient was eventually diagnosed with disseminated fusariosis. While on combination antifungal therapy, fever reappeared with pancytopenia and hepatosplenomegaly, and she was subsequently diagnosed with secondary Hemophagocytic lymphohistiocytosis (HLH) and was treated using the HLH 2004 protocol. The child responded to treatment well. This report highlights the high index of clinical suspicion, appropriate investigations needed to diagnose fusariosis and secondary HLH in pediatric oncology practice promptly, and the successful treatment outcome despite having them both.
Miliary Tuberculosis Mimicking Multiple Myeloma: A Rare Case
Authors: KAUR Jaspreet , RAJU Tagru , CHEEMA Yuvraj Singh , SİNGH Jasmine
Published: June 2022

Miliary tuberculosis or disseminated tuberculosis is one of India's most typical forms of tuberculosis. It can have varied presentations, from classical pulmonary disease to affection of extra-pulmonary sites, the most common being the vertebral column. With a wide array of clinical manifestations, differentiating disseminated tuberculosis from common malignancies is no less than a herculean task for a clinician. Keeping a high index of clinical suspicion and detailed work up in the right direction can save the clinician and the patient from an exhaustive ordeal of futile investigations. Here, we present a rare case of miliary tuberculosis masquerading as a common malignancy of the elderly, re-emphasizing the need for a systematic approach to such confusing presentations.
Differences in attitudes of students of Serbian language and students with non-linguistic background towards standard Serbian language
Authors: Miketić-Subotić Sanja , Kićović Milena
Published: June 2022

The aim of this paper is to present students' attitudes towards standard Serbian language and to find out if results verify the existence of standard language ideologies. In this study there were 240 participants (120 of which were students of University of Belgrade and 120 were students of University of Priština with temporary Head office in Kosovska Mitrovica). Half of that number was students of Serbian language and the other half were students with no linguistic background. The hypothesis we wanted to prove was that students of Serbian language have a more specific perception of standard Serbian language compared to their colleagues that have no formal linguistic education. Students filled in the questionnaire with attitudes they evaluated on a Likert-type scale, and the results were processed statistically. Results prove that students of Serbian language more often categorically agree or disagree with certain claims, that they are more prone to code switching and relating standard language to its traditional areas of use, that they have ideological attitudes towards standard language qualities and negative attitude towards "non-canonical" linguistic forms, all as a result of higher influence of standard language ideology upon them.
Trophic relationships and mining seasons of the Nepticulidae of Lithuania: an updated survey
Authors: Diškus Arūnas , Dobrynina Viktorija
Published: June 2022

This study provides updated summarised data on host-plant preferences and mining seasons of the Nepticulidae of the Lithuanian fauna. It revealed that the Lithuanian Nepticulidae are trophically associated with 34 genera and 14 families of host plants. Four of these host-plant families stand out in a number of mining Nepticulidae species and all together host about 80% of the Lithuanian Nepticulidae. As regards feeding specialisation, the fauna of the Lithuanian Nepticulidae consists of three constituents: monophagous species (about 44%), narrow oligophagous species (about 48%), and true oligophagous species (about 8%). There are two distinctive peaks of mining: the summer peak from mid-June until mid-July and the autumn peak from early September until mid-October, when most species mine simultaneously.

Georges Dumézils position i religionsforskningen siden 1994
Authors: Schjødt Jens Peter
Published: June 2022

Denne artikel udgøres af refleksioner over nogle af de ændringer, der har fundet sted inden for religionshistorien i forhold til den franske religionshistoriker Georges Dumézils teorier, siden Hans Jørgen Lundager Jensen og jeg selv, tilbage i 1994, skrev en bog med titlen Suveræniteten, kampen og frugtbarheden: Georges Dumézil og den indoeuropæiske ideologi. Efter en kort introduktion til den vigtigste del af Dumézils teori, nemlig den, der omhandler ‘den treledede ideologi’, hævdes det, at Dumézils betydning synes at være blevet mindre inden for i hvert fald studiet af førkristen nordisk religion. Grundene hertil forekommer mig at være en faldende interesse, inden for dette felt, for tre begreber, der er afgørende for Dumézils projekt, nemlig kontinuitet, komparativisme, og struktur, der alle desværre ser ud til at være mindre interessante i dag, ikke blot inden for feltet nordisk religion, men også mere generelt inden for humaniora.

Firmaets mand - Om organisationsloyalitet og managementvisdom i N.F.S. Grundtvigs salme “Talsmand! som paa Jorderige”
Authors: Baunvig Katrine Frøkjær
Published: June 2022

Dette essay handler om N.F.S. Grundtvigs forståelse af den kristne kirke som institution. Det vil sige: det handler om firmatænkningen og traditionsforpligtelsen i Grundtvigs forfatterskab. Mere nøjagtigt vil jeg med afsæt i salmen “Talsmand! som på Jorderige” argumentere for, at Grundtvig som embedsmand (præst, kirketænker, æresbiskop) og som salmedigter ønskede at bidrage konkret og konstruktivt til sin samtids kirkeliv med managementovervejelser og -redskaber til fællesskabsdannelse.

Authors: Toy Serdar , Tuncer Kutsi , Topal Murat , Aydın Ali
Published: June 2022

Background: Sinus tarsi syndrome is characterized by permanent pain on the anterolateral side of the ankle due to chronic inflammation characterized by fibrotic tissue remnants and synovitis accumulation after repeated traumatic injuries. Few studies have documented the outcome of injection treatments for sinus tarsi syndrome. We sought to determine the effects of corticosteroid and local anesthetic (CLA), platelet-rich plasma (PRP), and ozone injections on sinus tarsi syndrome.

Methods: Sixty patients with sinus tarsi syndrome were randomly divided into three treatment groups: CLA, PRP, and ozone injections. Outcome measures were visual analog scale, American Orthopedic Foot and Ankle Society Ankle-Hindfoot Scale (AOFAS), Foot Function Index, and Foot and Ankle Outcome Score before injection compared with 1, 3, and 6 months after injection.

Results: At the end of months 1, 3, and 6 after injection, significant improvements were observed in all three groups compared with baseline (P < .001 for all). At months 1 and 3, improvements in AOFAS scores were similar in the CLA and ozone groups; those in the PRP group were lower (P = .001 and P = .004, respectively). At month 1, improvements in Foot and Ankle Outcome Score were similar in the PRP and ozone groups and higher in the CLA group (P < .001). At 6-month follow-up, there were no significant differences in visual analog scale and Foot Function Index results among the groups (P > .05).

Conclusions: Ozone, CLA, or PRP injections could provide clinically significant functional improvement for at least 6 months in patients with sinus tarsi syndrome.

Published: June 2022

In recent years, the advent of cloud computing has transformed the field of computing and information technology. It has been enabling customers to rent virtual resources and take advantage of various on-demand services with the lowest costs. Despite the advantages of cloud computing, it faces several threats; an example is a distributed denial of service (DDoS) attack, which is considered among the most serious. This article presents real-time monitoring and detection of DDoS attacks on the cloud using a machine learning approach. Naïve Bayes, K-nearest neighbor, decision tree, and random forest machine learning classifiers have been selected to build a predictive model named “Real-Time DDoS flood Attack Monitoring and Detection RT-AMD.” The DDoS-2020 dataset was constructed with 70,020 records to evaluate RT-AMD’s accuracy. The DDoS-2020 contains three protocols for network/transport-level, which are TCP, DNS, and ICMP. This article evaluates the proposed model by comparing its accuracy with related works. Our model has shown improvement in the results and reached real-time attack detection using incremental learning. The model achieved 99.38% accuracy for the random forest in real-time on the cloud environment and 99.39% on local testing. The RT-AMD was evaluated on the NSL-KDD dataset as well, in which it achieved 99.30% accuracy in real-time in a cloud environment.
Assessing the size at maturity, spawning, and condition of the truncate soft-shell clam (Mya truncata) of southern Baffin Island, Nunavut, Canada
Authors: Wood Jessica M. , Donovan Meghan , Grant Scott M.
Published: June 2022

The truncate soft-shell clam Mya truncata is an important source of country food for Inuit communities across the territory of Nunavut, Canada. M. truncata also plays an important role in marine ecosystems, yet there is little understanding of their life history and condition in Canadian Arctic waters. To provide a foundation on which aspects of the life history and condition of M. truncata of Baffin Island can be monitored in the future with a changing climate and fishery development, this study estimated size at maturity and provides insights into the spawning cycle and weight-length condition indices of clams from inner Frobisher Bay and the north shore of the Hudson Strait. Male and female M. truncata exhibited similar lengths at 50% attainment of sexual maturity, 31 mm and 32 mm shell length (SL), respectively. Most (77%) of the sexually mature M. truncata collected from inner Frobisher Bay in late August and 35% of clams collected from the Hudson Strait in early September were in the ripe stage of gonadal development. These results lead us to suggest a spring spawning season and that M. truncata invest in gonadal development for the next year’s spawning during the late summer-early autumn ice-free season while phytoplankton concentrations are high. Dry bodyweight-SL relationships were used to show that M. truncata condition can differ significantly over small and large spatial scales based on plotted 95% confidence intervals.

Published: June 2022

Unusual presentation of Tuberculosis (TB) in anatomical locations like skeletal muscle which are atypical and not favorable for survival and multiplication of Mycobacterium tuberculosis.Commonly, muscle involvement is secondary. A direct inoculation (abdominal lymph node) or extension from underlying tubercular synovitis and osteomyelitis may involve an abdominal muscle. The case report is about a 43-year-old female who presented with an abdominal lump for past one month. There was no history of cough, weight loss, pain abdomen, recurrent vomiting, breathlessness and no history of TB or close contact with TB patient. Ultrasound (USG) and Contrast Enhanced Computed Tomography (CECT) of the abdomen revealed loculated collection in right rectusabdominis muscle, and USG-guided aspiration for cytology, culture and Cartridge Based Nucleic Acid Amplification Test (CBNAAT) confirmed tubercular abscess. The patient was managed as per National Tuberculosis Elimination Programme and responded well with antitubercular drug therapy for six months. This case throws light on to the possibility of tubercular infection in atypical anatomical locations as primary foci, especially in those areas where tuberculosis is endemic.

Published: June 2022

Dilated Cardiomyopathy (DCM) is a non ischaemic heart muscle disease with left or biventricular dilatation and systolic dysfunction in the absence of other heart disease. DCM can lead to substantial morbidity and mortality due to complications like heart failure and arrhythmias. Intraoperative management of a patient with acute decompensated heart failure due to DCM is a challenge for anaesthesiologist. This case report is about a 58-year-old male patient, who was a known case of DCM with low left ventricular ejection fraction (10-15%), chronic kidney disease, chronic pancreatitis and hypertension. He came to the emergency department with acute decompensated heart failure and subacute intestinal obstruction. After initial stabilisation, he was scheduled to undergo emergency exploratory laparotomy for obstruction. Intraoperative management of the patient was done successfully by ensuring normovolemia, avoiding ventricular afterload, avoiding myocardial depression and providing adequate pain relief through multimodal analgesia. The article mentions various anaesthetic concerns, risks involved and preparations required in such a case.
Minimal Side-effects and Adequate Analgesia in Spinal Anaesthesia: A Randomised Double Blinded Study Comparing Buprenorphine and Clonidine
Authors: Ramya DM , Vikas KN , Rao Sudhir S
Published: June 2022

Introduction: Postoperative patient management includes managing the acute postoperative pain as well as the sideeffects associated with the use of various medications in pain management. Opioids like buprenorphine are excellent in providing analgesia but causes nausea, vomiting among other side-effects. Clonidine is another class of drugs used as an adjuvant but the dose related sympatholytic effect is troublesome to handle. Aim: To evaluate the efficacy buprenorphine (45 μg) and clonidine (22.5 μg) when used in low doses as an adjuvant in spinal anaesthesia and to study the incidence of the most common side-effects. Materials and Methods: The double-blinded randomised clinical study was conducted in the Bangalore Baptist Hospital, Hebbal, Bengaluru, karnataka, India, from January 2014 to October 2014. Hundred patients, aged between 18-55 years, American Society of Anaesthesiologists (ASA) grade I and II, scheduled for lower limb and lower abdominal surgeries were studied. They were divided randomly into two groups i.e, group X and group Y of 50 each. All patients were given 15 mg (3 mL) of 0.5% hyperbaric bupivacaine and along with that the patients in the group X (buprenorphine group) were given 45 μg (0.15 mL) of buprenorphine and the patients in group Y (clonidine group) were given 22.5 μg (0.15 mL) of clonidine. The duration of analgesia, requirement of supplemental analgesics and incidence of sideeffects were noted. Results: The duration of analgesia was found to be longer in the buprenorphine group (448.47±78.08 min) when compared to the clonidine group (311.70±71.92 min). The requirement of supplemental analgesics were, 94% in buprenorphine group required 1-2 doses and 92% in the clonidine group required 3-5 doses of analgesics in the 1st 24 hours, postoperatively. Among the side-effects, 4% of the patients in the buprenorphine group had bradycardia and hypotension, while 6% had nausea and vomiting. In comparison, 18% of patients in the clonidine group had hypotension, nausea (14%), vomiting (12%) and bradycardia (6%). Conclusion: Both buprenorphine and clonidine, in low doses, provide effective postoperative analgesia with minimal sideeffects; while in comparison, buprenorphine has been found to fair better.
Usefulness of Reticulocyte Haemoglobin Equivalent in the Evaluation of Iron Deficiency Status: A Cross-sectional Study
Authors: Mouleeswaran KS , Einstien Dinisha , Prathiba A
Published: June 2022

Introduction: Iron deficiency is the most frequent cause of nutritional anaemia. Evaluation of parameters like serum ferritin and iron is critically important for evaluation of the iron status of patients and diagnosis of Iron Deficiency Anaemia (IDA). But in inflammatory disorders, ferritin concentration may be normal or increased due to the acute phase response, resulting in inaccurate interpretation of the iron status. Similarly, the serum Iron levels may be high in cases of thalassaemia with combined iron deficiency. Reticulocyte Haemoglobin equivalent (RET-He) which correlates to the iron content in reticulocytes is effective, convenient and provides useful information for the immediate diagnosis and treatment of iron deficient states. Aim: The aim of this study was to evaluate the diagnostic performance of RET-He level by comparing it with the iron status of the patients. Materials and Methods: This cross-sectional study was done in Department of Pathology at Tagore Medical College and Hospital, Chennai, Tamil Nadu, India, from December 2020 to November 2021. The complete blood count, RET-He, serum iron and serum ferritin levels of 406 patients with microcytic hypochromic anaemia and dimorphic anaemia were reviewed and RET-He levels were compared with the serum iron and ferritin levels. The p-value was calculated using Statistical Package for Social Sciences (SPSS) IBM software version 28.0. The sensitivity of RET-He and serum ferritin levels in evaluating iron deficiency were calculated. Results: Low RET-He was observed in 394 cases, low serum iron in 401 cases and reduced serum ferritin in 376 cases. Twenty one of 34 cases of IDA with concomitant inflammation showed low RET-He and serum iron, despite normal to high serum ferritin levels. Five cases of iron deficiency with concomitant Haemoglobin defect also showed low RET-He levels and serum ferritin, whereas the serum iron was raised. Low RET-He was observed in 17 cases of dual deficiency anaemia i.e., iron deficiency along with vitamin B12/folate deficiency. Conclusion: It was concluded that measurement of the reticulocyte haemoglobin content provides useful information for the diagnosis, treatment and monitoring of iron deficient states.

Kawasaki disease (KD) is an acute febrile systemic necrotizing medium and small vasculitis in children, mainly affecting children under 5 years old, and has become the main cause of pediatric acquired heart disease in developing countries.  The exact etiology of this disease is still unclear. At present, researcheson KD are mostly limited to susceptibility gene, infection and immunity.  How ever, there are few studies on the correlation between intestinal flora and KD. In recent years, some studies have found that KD is related to the imbalance of intestinal flora, and the abundance and structure of intestinal flora in children with KD change, which contributes to the occurrence and development of KD by affecting the release of inflammatory factors, damaging the intestinal barrier function and activating the autoimmune system.  This review aims to elucidate the relationship between gut microflora and KD, and the mechanism of action and that of probiotics

Equilíbrios múltiplos e tragédias dos comuns: uma abordagem de jogos evolucionários
Authors: Drumond Carlos Eduardo Iwai
Published: June 2022

A tragédia dos comuns, originalmente prevista por Hardin (1968), diz respeito à uma situação na qual os agentes, buscando maximizar sua satisfação individual, acabam por esgotar os recursos naturais ou outros recursos de uso comum. Neste trabalho o uso dos recursos naturais é modelado de maneira alternativa, a partir de um jogo evolucionário. Neste jogo tanto a solução clássica da tragédia dos comuns quanto à gestão coletiva sustentável pode emergir da interação entre os agentes, o que implica num jogo com equilíbrios múltiplos.

The fatty acid synthase inhibitor C75 differentially affects the adipogenic differentiation of multipotent cells and preadipocytes
Authors: Tseng Kuo‐Yun , Liu Ko‐Hung , Wu Hung‐Ming , Lin Shankung
Published: June 2022

Previously, we revealed the dual enhancing effect of netoglitazone, an agonist of the peroxisome proliferator‐activated receptor γ, on adipogenesis and osteoblastogenesis, and reported that fatty acid synthase (FASN) knockdown selectively repressed its pro‐adipogenic effect. Here, we examined if a FASN inhibitor, C75, could selectively repress the pro‐adipogenic effect of netoglitazone. Surprisingly, C75 promoted the adipogenic differentiation of multipotent C3H10T1/2 cells but inhibited 3T3‐L1 preadipocytes. By identifying glycogen synthase kinase‐3β and intracellular cAMP levels as regulatory targets of C75, we ultimately found the differential expression of adenosine receptor 3 (AR3) and AR2a on these cells. Inhibition of AR3 on C3H10T1/2 and AR2a on 3T3‐L1 inhibited the effects of C75 on the differentiation of these cells. Our findings imply that cell‐type‐specific AR expression might account for the differential adipogenic effects of C75.

2D perovskites possess superior humidity stability but inferior power conversion efficiency (PCE) compared with 3D perovskites due to their typically insulating spacers. Size of the spacer cation is determinative for the formation of 2D perovskite, and fullerene is believed not to be capable of templating 2D perovskite structure because of its larger size than the width of the lead‐halide octahedron despite its well‐known strong electron‐accepting ability. Herein, a novel amino‐functionalized fullerene derivative (abbreviated as C60‐BPAM) is developed and an ‘improbable’ spacer for 2D/3D hybrid perovskite solar cells (PSCs), achieving enhanced electron transport is applied. Unlike most of the reported alkylammonium spacers that are based on insulating organic tails, the incorporation of a highly conductive fullerene tail within C60‐BPAM2+ leads to increased electron density in 2D/3D perovskite and induces an additional built‐in electric field, facilitating electron transport in PSCs. Besides, the 2D/3D hybrid structure helps to passivate both of the shallow‐ and deep‐level defects within perovskite. As a result, the PCE of 2D/3D PSCs improves from 19.36% (3D MAPbI3 PSCs) to 20.21%. Moreover, the 2D/3D PSCs show significant improvement in the humidity stability compared to the 3D counterparts.
All‐Direct‐Ink‐Writing of Artistic Supercapacitors: Toward On‐Demand Embodied Power Sources
Authors: Lee Seong‐Sun , Kim Se‐Hee , Ahn David B. , Lee Kwon‐Hyung , Jo Yejin , Jeong Sunho , Lee Sang‐Young
Published: June 2022

Despite the extensive studies on printed power sources for user‐customized shape‐versatile electronics, most of them have still focused on printing of electrochemically active materials, with little attention to passive components such as current collectors and packaging, thus hindering their versatile application. Here, all‐direct‐ink‐writing (DIW) of artistic supercapacitors (ASCs) as a facile and scalable strategy to enable power source‐unitized monolithic electronic devices with various form factors is demonstrated. Interdigitated nickel current collectors embedded inside a polyurethane support layer are fabricated using DIW printing, which can facilitate the subsequent printing of multi‐scale, ultrathick electrodes. Interstitial voids between the DIW‐printed adjacent electrode layers are densely infiltrated by click‐crosslinkable electrolyte inks with well‐tuned rheological properties. The void‐free electrode/electrolyte assembly is conformally printed with a waterproof packaging ink to enable hermetic encapsulation, eventually producing all‐DIW‐printed ASCs with efficient space utilization, design diversity, and dimensional scalability. Notably, the resulting ASC can be seamlessly unitized with arbitrary‐shaped 3D objects (e.g., miniature pagodas), allowing for the potential development of on‐demand embodied power sources for electronic devices.

Hydrogel‐shelled microcapsules allow communication with the surrounding through molecule‐selective exchanges, serving as microcarriers for cells, drugs, catalysts, and nanoparticle sensors. However, the low mechanical stability of hydrogels has restricted their use in strong shear flows or compressive fields. Here, microcapsules are designed composed of water core and double‐network (DN) hydrogel shell using water‐in‐oil‐in‐water‐in‐oil triple‐emulsion templates to secure high mechanical stability as well as molecular size‐selective permeation. Monodisperse triple‐emulsion droplets are prepared using microfluidic devices. The core water contains divalent ions and the outer water layer contains poly(ethylene glycol)diacrylate (PEGDA) and sodium alginate. The PEGDA is first photocrosslinked by ultraviolet irradiation and the alginate is second ionically crosslinked with an infusion of divalent ions from the core by rupturing the middle oil layer. The resulting DN shells show excellent mechanical stability in comparison with single‐network (SN) shells made of PEGDA only. Enhanced elasticity of the DN enables the microcapsules to elastically deform and fully recover the original state for wide ranges of strain and strain rate. Moreover, the DN shells show a threshold force for the shell rupture almost one order of magnitude larger than the SN and maintain their integrity under violent shear flows.

Transition metal dichalcogenide (TMD) quantum dots (QDs) with defects have attracted interesting chemistry due to the contribution of vacancies to their unique optical, physical, catalytic, and electrical properties. Engineering defined defects into molybdenum sulfide (MoS2) QDs is challenging. Herein, by applying a mild biomineralization‐assisted bottom‐up strategy, blue photoluminescent MoS2 QDs (B‐QDs) with a high density of defects are fabricated. The two‐stage synthesis begins with a bottom‐up synthesis of original MoS2 QDs (O‐QDs) through chemical reactions of Mo and sulfide ions, followed by alkaline etching that creates high sulfur‐vacancy defects to eventually form B‐QDs. Alkaline etching significantly increases the photoluminescence (PL) and photo‐oxidation. An increase in defect density is shown to bring about increased active sites and decreased bandgap energy; which is further validated with density functional theory calculations. There is strengthened binding affinity between QDs and O2 due to lower gap energy (∆EST) between S1 and T1, accompanied with improved intersystem crossing (ISC) efficiency. Lowered gap energy contributes to assist e−–h+ pair formation and the strengthened binding affinity between QDs and 3O2. Defect engineering unravels another dimension of material properties control and can bring fresh new applications to otherwise well characterized TMD nanomaterials.

Authors: Jung In‐Jun , Chang Seung‐Hwan
Published: June 2022

This study presents novel, self‐powered smart shoes that can detect various gait patterns and harvest electrical energy. A functional ribbon unit made of polyvinylidene fluoride (PVDF) ribbon and conductive fabric tape is used for the energy harvester, and a dynamic sensor is used for monitoring the gait patterns. To determine the optimal number of ribbon units and effective elongation levels for energy harvesting, static tensile and repetitive electromechanical tests are performed. In addition, the generated output voltage and energy storage capacity according to the ribbon configuration are experimentally investigated. To enhance the energy‐harvesting efficiency of the functional ribbon unit, a high‐stiffness lightweight carbon composite frame is installed at the heel part inside the smart shoes, and three ribbon units are fastened to it. From the performance test, it is concluded that the harvester generates sufficient electric power, which is stored in successive capacitors; subsequently, the generated electric power is stored in a lithium‐ion battery. Moreover, various gait patterns are successfully identified, and gait speed is estimated using the proposed smart shoes.

High‐index all‐dielectric resonators have been developed into an important platform for light manipulation at the nanoscale over the past decade. Although they are widely used as 2D materials, transition metal dichalcogenides (TMDCs), as an emerging all‐dielectric material, have also been used to fabricate optical nanoantennas that support multipolar Mie resonances. However, their fabrication depends heavily on electron‐beam lithography (EBL) or focused ion beam (FIB), which is expensive and time‐consuming for practical applications. To address this issue, here, a fast low‐cost method is put forward which combines polystyrene (PS) nanospheres with physical vapor deposition by electron‐beam evaporation and magnetron sputtering to fabricate WS2 nanodisks in a mass‐production manner. After annealing, the A‐ and B‐exciton features as well as anapole states are observed in the scattering spectra of WS2 nanodisks. The light scattering anisotropy of individual WS2 nanodisks and spectral tunability of the anapole are studied. In addition, absorption enhancement due to the strong field localization of anapole states in hexagonal WS2 nanodisk arrays is numerically demonstrated. This work manifests that this etching‐free method is promising for fabrication of scalable TMDC nanodisks suitable for practical applications.
Distinctive Photo‐Induced Memory Effect in Heterostructure of 2D Van Der Waals Materials and Lanthanum Aluminate

Published: June 2022

The role of interface in atomically thin two‐dimensional (2D) van der Waals materials is crucial in their novel optoelectronic properties. This study reports a mixed‐dimensional optoelectronic memory device based on a heterostructure comprising 2D monolayer molybdenum disulfide and bulk lanthanum aluminate. The reversible photo‐induced doping process accompanying persistent photocurrent phenomena is controlled using a gate voltage which is applied across the lanthanum aluminate dielectric substrate under light illumination. The extremely low gate electric field (<2 × 103 V cm−1) and the opposite gate voltage polarity compared with the general photo‐doping cases indicate that the conventional band bending mechanism cannot be applied to this optoelectronic device. This distinctive photo‐induced memory concept is validated in lanthanum aluminate‐based heterostructures with other 2D materials such as graphene and tungsten diselenide. It is postulated that the heterostructure of atomically thin van der Waals materials that are in contact with various functional oxides provides a novel platform for next‐generation optoelectronic devices.

Single memristor crossbar arrays are a very promising approach to reduce the power consumption of deep learning accelerators. In parallel, the emerging bio‐inspired spiking neural networks (SNNs) offer very low power consumption with satisfactory performance on complex artificial intelligence tasks. In such neural networks, synaptic weights can be stored in nonvolatile memories. The latter are massively read during inference, which can lead to device failure. In this context, a 1S1R (1 Selector 1 Resistor) device composed of a HfO2‐based OxRAM memory stacked on a Ge‐Se‐Sb‐N‐based ovonic threshold switch (OTS) back‐end selector is proposed for high‐density binarized SNNs (BSNNs) synaptic weight hardware implementation. An extensive experimental statistical study combined with a novel Monte Carlo model allows to deeply analyze the OTS switching dynamics based on field‐driven stochastic nucleation of conductive dots in the layer. This allows quantifying the occurrence frequency of OTS erratic switching as a function of the applied voltages and 1S1R reading frequency. The associated 1S1R reading error rate is calculated. Focusing on the standard machine learning MNIST image recognition task, BSNN figures of merit (footprint, electrical consumption during inference, frequency of inference, accuracy, and tolerance to errors) are optimized by engineering the network topology, training procedure, and activations sparsity.

As substantial progress has been made to miniaturize intelligent microsystems to the sub‐square‐millimeter scale, there is a desperate need to move beyond existing microbattery technologies to offer adequate energy at the same footprint. A micro‐origami technology able to wind up a flat layer stack into a Swiss roll presents a promising approach in this regard because it mimics the most successful way to make energy‐dense full‐sized batteries. Here, an on‐chip Swiss‐roll current collector made via the micro‐origami process is developed and it is infused with a MnO2 slurry comprising a zincophilic binder. The zincophilic binder layer enhances zinc ion transportability and suppresses MnO2 dissolution. The MnO2 Swiss‐roll microelectrode is used to create an on‐chip microbattery with a small electrode footprint area of 0.75 mm2, which shows a footprint capacity up to 3.3 mAh cm–2. The microbattery demonstrates a reversible capacity of more than 1 mAh cm–2 for 150 cycles. The battery stability can be improved to over 600 cycles at a 50% depth of discharge. An on‐chip integration of a microsystem with the microbattery is demonstrated. The microbatteries set foot in the untrodden sub‐square‐millimeter area providing adequate energy for ever more miniaturized intelligent microsystems.

At present, the development of high‐performance protein imprinted materials is still a research hotspot in the field of protein imprinting. Herein, anti‐protein adsorption segment (CBMA)‐assisted self‐driven bovine serum albumin (BSA) surface imprinted fibers MTCFs@SIP@CBMA with high recognition selectivity are pioneered using the strategies of combining magnetic nanomaterial surface imprinting technique with amino‐Michael addition. The special structure of the carrier MTCFs endows MTCFs@SIP@CBMA with magnetic performance and self‐driven adsorption performance, which simplifies the separation process while improving the adsorption capacity and accelerating the adsorption rate. The adsorption capacity for BSA reached 390 ± 20 mg/g within 30 min. The introduction of CBMA segments on the surface after imprinting by amino‐Michael addition makes its polymer chain length and position controllable. Under the strongest anti‐nonspecific adsorption effect, MTCFs@SIP@CBMA exhibit excellent specific identification to BSA from mixed proteins. Additionally, MTCFs@SIP@CBMA show considerable reusability. Therefore, MTCFs@SIP@CBMA are expected to be applied in efficient separation of proteins in biological samples.
