Role of the newly synthesized brightener in modification of surface properties of Zn-Ni alloy electrodeposited on steel substrate
Authors: Kavirajwar Jyoti S. , Shivarudraiah Basavanna , Arthoba Nayaka Yanjerappa
Published: April 2019

In the present study, a new brightener was synthesized by condensation of salicylaldehyde and cysteine hydrochloride (SC). To examine the influence of SC on the nucleation mechanism of Zn-Ni alloy, electrodeposition, cyclic voltammetric and chronoamperometric studies were carried out. The model of Schariffker and Hills was used to analyze current transients which explained the electrocrystallization process of Zn-Ni alloy. It is revealed that Zn-Ni electrocrystallization process in presence of SC is regulated by instantaneous nucleation mechanism. The corrosion studies were done for the bright and dull zinc-nickel alloy coatings in 3.5 wt.% NaCl solution, using potentiodynamic polarization and electro­chemical impedance spectroscopic techniques. The phase structure, surface morphology and brightness of the deposit were characterized by means of X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM) and reflectance studies. These studies revealed the role of SC in producing a bright Zn-Ni alloy coating on mild steel substrate and also showed its improved corrosion resistant nature.
Regulierungen der Religionsfreiheit
Authors: Kippenberg Hans G.
Published: April 2019

Article 18 on the freedom of religion in the Declaration of Human Rights from 1948 presented religious studies with the task of rethinking its concept of religion. Through it, religious organisations were granted inviolable rights. Now religion is also manifesting itself in international religious NGOs, whose public activities have made them global players and, as a result, possible partners in or even opponents of states’ foreign policies.
The majority of studies on religious freedom do not go beyond Article 18 and its emergence. They rarely examine the question of how it should be implemented in the further explanations and institutions of the UN and those of the EU, and thus constitute a void in research into the history of religion, religious sociology, religious studies and theology.
In this study, the author focuses on how freedom of religion has been realised and regulated both in terms of universal and European human rights as well as in the rulings of the European Court of Human Rights in Strasbourg.
§ 278a ZPO als Schnittstelle zwischen Gerichtsverfahren und außergerichtlicher Mediation
Authors: Bushart Clemens
Published: April 2019

Choosing the appropriate conflict resolution procedure is paramount to proper and effective conflict management. An important impetus for the choice of the most suitable procedure is provided by § 278a of the ZPO (Germany’s Code of Civil Procedure), which enables judges to suggest a range of out-of-court alternative dispute resolution procedures, including mediation.
In this study, the author analyses the regulatory content of § 278a of the ZPO as well as the function and potential of the provision to act as an interface between court proceedings and extrajudicial mediation. Using the finding that judges rarely propose that litigants switch to extrajudicial mediation, the author empirically examines the reasons for the cautious application of § 278a of the ZPO and develops a set of comprehensive recommendations to optimise the procedural interface.

Published: April 2019

Aim of study was to evaluate the development of cardiac hypertrophy (CH) in response to left ventricle (LV) volume overload (VO) caused by chronic aortic valve regurgitation (AR) in male and female rats treated or not with angiotensin II receptor blocker (ARB), valsartan. We studied 8 groups of Wistar rats: male or female, AR or sham-operated (sham) and treated or not with valsartan (30 mg/kg/day) for 9 weeks starting one week before AR surgical induction. As expected, VO from AR resulted for both male and female rats in significant LV dilation (39% vs. 40% increase of end-diastolic LV diameter, respectively; p<0.0001) and CH (53% vs. 64% increase of heart weight, respectively; p<0.0001) compared to sham. Sex differences were observed in the LV wall thickening in response to VO. In untreated AR males, relative LV wall thickness (a ratio of wall thickness to end-diastolic diameter) was reduced compared to sham, whereas this ratio in females remained unchanged. ARB treatment did not prevent LV dilation for both male and female animals but reversed LV wall thickening in females. Systolic and diastolic functions in AR animals were altered similarly for both sexes compared to sham. ARB treatment did not improve systolic function but help normalizing diastolic parameters in female AR rats. Increased LV expression of Anp and Bnp genes was normalized by ARB treatment in AR females but not in males. Other hypertrophy gene markers (Fos, Trpc6, Klf15, Myh6 and Myh7) were not modulated by ARB treatment. The same was true for genes related to LV extracellular matrix remodeling (Col1a1, Col3a1, Fn1, Mmp2, Timp1 and Lox). In summary, ARB treatment of rats with severe AR blocked the female-specific hypertrophic response characterized by LV chamber wall thickening. LV dilation, on the other hand, was not significantly decreased by ARB treatment.
Towards a quantitative model of epidemics during conflicts
Authors: Banerjee Soumya
Published: April 2019

Epidemics may both contribute to and arise as a result of conflict. The effects of conflict on infectious diseases are complex and there have been confounding observations of both increase and decrease in disease outbreaks during and after conflicts. However there is no unified mathematical model that explains all these counter-intuitive observations. There is an urgent need for a quantitative framework for modelling conflicts and epidemics. We introduce a set of mathematical models to understand the role of conflicts in epidemics. Our mathematical framework has the potential to explain the counterintuitive observations and the complex role of human conflicts in epidemics. Our work suggests that aid and peacekeeping organizations should take an integrated approach that combines public health measures, socio-economic development, and peacekeeping in the conflict zone. Our approach exemplifies the role of non-linear thinking in complex systems like human societies. We view our work as a step towards a quantitative model of disease spread in conflicts.
Lymph node inspired computing: immune system inspired architectures for human-engineered complex systems
Authors: Banerjee Soumya
Published: April 2019

The immune system is a distributed decentralized system that functions without any centralized control. The immune system has millions of cells that function somewhat independently and can detect and respond to pathogens with considerable speed and efficiency. Lymph nodes are physical anatomical structures that allow the immune system to rapidly detect pathogens and mobilize cells to respond to it. Lymph nodes function as: 1) information processing centers, and 2) a distributed detection and response network. We introduce biologically inspired computing that uses lymph nodes as inspiration. We outline applications to diverse domains like mobile robots, distributed computing clusters, peer-to-peer networks and online social networks. We argue that lymph node inspired computing systems provide powerful metaphors for distributed computing and complement existing artificial immune systems. We view our work as a first step towards holistic simulations of the immune system that would capture all the complexities and the power of a complex adaptive system like the immune system. Ultimately this would lead to holistic immune system inspired computing that captures all the complexities and power of the immune system in human-engineered complex systems.

Understanding the principles governing neuronal diversity is a fundamental goal for neuroscience. Here, we provide an anatomical and transcriptomic database of nearly 200 genetically identified cell populations. By separately analyzing the robustness and pattern of expression differences across these cell populations, we identify two gene classes contributing distinctly to neuronal diversity. Short homeobox transcription factors distinguish neuronal populations combinatorially, and exhibit extremely low transcriptional noise, enabling highly robust expression differences. Long neuronal effector genes, such as channels and cell adhesion molecules, contribute disproportionately to neuronal diversity, based on their patterns rather than robustness of expression differences. By linking transcriptional identity to genetic strains and anatomical atlases, we provide an extensive resource for further investigation of mouse neuronal cell types.

Published: April 2019

Due to the many advantages of microstrip patch antennas, nowadays, microstrip patch antennas are mostly preferred in biomedical areas. This study aims two antenna structures, as both transceiver and receiver, have same dimensions are designed to produce solution of the difficulties in pathology. For antennas with an operating frequency of 2.45 GHz, FR-4 substrate material with a value of 4.4 dielectrics is used. A model has been prepared to detect the presence of skin cancer with the designed antennas. The model is a method of determining E-field and scattering parameters differences between two antennas of cancerous and normal tissue specimens placed on the glass slides. The same antennas and experimental setup were prepared with the normal and cancerous structure of the skin tissue prepared by pathologists. Thus, scattering parameters are measured and their differences are determined. It has been shown that cancerous tissue can be determined with different values obtained as a result. Ansys HFSS program is used for designs and simulations.

Published: April 2019

Marine biodiversity and derived ecosystem services are critical to the healthy functioning of marine ecosystems, and to human economic and societal well-being. Thus, an understanding of marine biodiversity in different ecosystems is necessary for their conservation and management. Coral reefs in particular are noted for their high levels of biodiversity, and among the world’s coral reefs, the subtropical Ryukyu Islands (RYS; also known as the Nansei Islands) in Japan have been shown to harbor very high levels of marine biodiversity. This study provides an overview of the state of marine biodiversity research in the RYS. First, we examined the amount of English language scientific literature in the Web of Science (WoS; 1995–2017) on six selected representative taxa spanning protists to vertebrates across six geographic sub-regions in the RYS. Our results show clear taxonomic and sub-region bias, with research on Pisces, Cnidaria, and Crustacea to be much more common than on Dinoflagellata, Echinodermata, and Mollusca. Such research was more commonly conducted in sub-regions with larger human populations (Okinawa, Yaeyama). Additional analyses with the Ocean Biogeographic Information System (OBIS) records show that within sub-regions, records are concentrated in areas directly around marine research stations and institutes (if present), further showing geographical bias within sub-regions. While not surprising, the results indicate a need to address ‘understudied’ taxa in ‘understudied sub-regions’ (Tokara, Miyako, Yakutane, Amami Oshima), particularly sub-regions away from marine research stations. Second, we compared the numbers of English language scientific papers on eight ecological topics for the RYS with numbers from selected major coral reef regions of the world; the Caribbean (CAR), Great Barrier Reef (GBR), and the Red Sea (RES). As expected, the numbers for all topics in the RYS were well below numbers from all other regions, yet within this disparity, research in the RYS on ‘marine protected areas’ and ‘herbivory’ was an order of magnitude lower than numbers in other regions. Additionally, while manuscript numbers on the RYS have increased from 1995 to 2016, the rate of increase (4.0 times) was seen to be lower than those in the CAR, RES, and GBR (4.6–8.4 times). Coral reefs in the RYS feature high levels of both endemism and anthropogenic threats, and subsequently they contain a concentration of some of the world’s most critically endangered marine species. To protect these threatened species and coral reef ecosystems, more data are needed to fill the research gaps identified in this study.

Closed cerebral hemorrhage (CCH) is a common symptom in traumatic brain injury (TBI) patients who suffer intracranial hemorrhage with the dura mater remaining intact. The diagnosis of CCH patients prior to hospitalization and in the early stage of the disease can help patients get earlier treatments that improve outcomes. In this study, a noncontact, portable system for early TBI-induced CCH detection was constructed that measures the magnetic induction phase shift (MIPS), which is associated with the mean brain conductivity caused by the ratio between the liquid (blood/CSF and the intracranial tissues) change. To evaluate the performance of this system, a rabbit CCH model with two severity levels was established based on the horizontal biological impactor BIM-II, whose feasibility was verified by computed tomography images of three sections and three serial slices. There were two groups involved in the experiments (group 1 with 10 TBI rabbits were simulated by hammer hit with air pressure of 600 kPa by BIM-II and group 2 with 10 TBI rabbits were simulated with 650 kPa). The MIPS values of the two groups were obtained within 30 min before and after injury. In group 1, the MIPS values showed a constant downward trend with a minimum value of −11.17 ± 2.91° at the 30th min after 600 kPa impact by BIM-II. After the 650 kPa impact, the MIPS values in group 2 showed a constant downward trend until the 25th min, with a minimum value of −16.81 ± 2.10°. Unlike group 1, the MIPS values showed an upward trend after that point. Before the injury, the MIPS values in both group 1 and group 2 did not obviously change within the 30 min measurement. Using a support vector machine at the same time point after injury, the classification accuracy of the two types of severity was shown to be beyond 90%. Combined with CCH pathological mechanisms, this system can not only achieve the detection of early functional changes in CCH but can also distinguish different severities of CCH.
Crowdsourcing in medical research: concepts and applications
Authors: Tucker Joseph D. , Day Suzanne , Tang Weiming , Bayus Barry
Published: April 2019

Crowdsourcing shifts medical research from a closed environment to an open collaboration between the public and researchers. We define crowdsourcing as an approach to problem solving which involves an organization having a large group attempt to solve a problem or part of a problem, then sharing solutions. Crowdsourcing allows large groups of individuals to participate in medical research through innovation challenges, hackathons, and related activities. The purpose of this literature review is to examine the definition, concepts, and applications of crowdsourcing in medicine. This multi-disciplinary review defines crowdsourcing for medicine, identifies conceptual antecedents (collective intelligence and open source models), and explores implications of the approach. Several critiques of crowdsourcing are also examined. Although several crowdsourcing definitions exist, there are two essential elements: (1) having a large group of individuals, including those with skills and those without skills, propose potential solutions; (2) sharing solutions through implementation or open access materials. The public can be a central force in contributing to formative, pre-clinical, and clinical research. A growing evidence base suggests that crowdsourcing in medicine can result in high-quality outcomes, broad community engagement, and more open science.

Despite being the most dominant and widespread small fish species in the lakes along the middle and lower reaches of the Yangtze River basin,Toxabramis swinhonishas been paid little attention by fisheries scientists and little is known about its population characteristics. For this reason, we estimated age, growth, mortality and recruitment of this species based on three shallow lakes, Biandantang Lake, Shengjin Lake and Kuilei Lake (BDT, SJH and KLH, respectively) in this region. A total of 13,585 (8,818 in BDT, 2,207 in SJH and 2,560 in KLH) individuals were collected during monthly sampling from July 2016 to September 2017. The results revealed that the age structures ofT. swinhonisconsisted of four age groups (0+–3+), with 0+–1+year old fish comprising more than 98% of the samples. Allometric growth patterns were displayed by fish from all sampling sites and the von Bertalanffy growth functions estimated wereLt= 173.25 (1 – e−1.20 (t + 1.09)): BDT;Lt= 162.75 (1 – e−1.20 (t + 1.08)): SJH andLt= 215.25 (1 – e−1.20 (t + 1.12)): KLH, respectively. The rates of total mortality (Z), natural mortality (M) and fishing mortality (F) at BDT, SJH and KLH were computed as 5.82, 5.50 and 4.55 year−1; 1.89, 1.87 and 1.75 year−1; 3.93, 3.63 and 2.80 year−1, respectively. Meanwhile, growth performance indices (φ′) were 0.68 (in BDT), 0.66 (in SJH) and 0.62 (in KLH), which indicated thatT. swinhoniswere overfished slightly in all study areas. Area-specific recruitment patterns were similar to each other, displaying evidence of batch spawning, with major peaks in April and August, accounting for 92.21% (BDT), 88.21% (SJH) and 88.73% (KLH) of total recruitment, respectively. These results showed that brief generation-time, fast growth rate, relatively high natural mortality rate and strong reproductive capacity (r-strategies) are reasons why this species became the most dominant species in many lakes of China.

Published: April 2019

No mundo corporativo muito se investe em tecnologia, processos especializados e técnicas cada vez mais avançadas para se alcançar as tão planejadas metas de crescimento. Porém, há um fator que está por trás de todas as técnicas e processos a ser adotado, um item sem o qual nada funcionaria: o fator humano. No cenário atual, é preciso conhecer a expectativa profissional de cada funcionário e procurar atendê-las. Devido à passagem da Era Industrial para a Era da Informação, as organizações buscam fornecedores de serviços cerebrais; necessitam das habilidades com as mãos, mas a habilidade do cérebro é mais valorizada. Pesquisas apontam que hoje, o que mais atrai os profissionais de secretariado é o Plano de Carreira. Remuneração, seja fixa ou variável, tornou-se um item de segunda ou até terceira prioridade. Isto se dá porque o perfil destes profissionais é buscar crescimento pessoal e profissional. Estes dados ficam comprovados na pesquisa primária elaborada neste trabalho. A maioria dos profissionais entrevistados, especialmente os jovens, considera a carreira como sua maior prioridade. Com base no que foi analisado e comparando aos estudos acadêmicos abordados no decorrer do trabalho, é correto confirmar que há uma tendência comprovada em pesquisas primárias e secundárias de que o salário está saindo de cena quando o assunto é reter talentos. Mais que isso, para reter o talento é preciso estudá-lo, pois conforme constatado a prioridade vai variar de acordo com a fase pessoal e profissional em que o indivíduo se encontra.
Assédio Moral no Trabalho: A Compreensão dos Trabalhadores sobre a Violência
Authors: Nunes Thiago Soares , Tolfo Suzana da Rosa , Espinosa Leonor María Cantera
Published: April 2019

O assédio moral no trabalho é uma situação já recorrente há muito tempo, porém somente nas últimas décadas que realmente foi identificado como um fenômeno destruidor do ambiente laboral, não apenas provocando a diminuição da produtividade, mas também favorecendo o absenteísmo devido aos efeitos/consequências que provoca (Hirigoyen, 2008). Por sua vez, uma das grandes dificuldades de combater e coibir a violência é a informação sobre ele, seu conceito e características. Neste sentido, o presente artigo teve por objetivo descrever a definição de assédio moral no trabalho a partir do relato dos participantes sobre o tema em um termo/palavra. Para tanto utilizou-se de três pesquisas que ocorreram em 2008, 2010, e 2014-15, tendo como público-alvo trabalhadores de diversos setores, como por exemplo, bancário, docentes e técnico-administrativos, saúde, justiça, e demais. Como conclusões, os participantes definiram o assédio moral prioritariamente por aspectos da prática hostil, como humilhação, desrespeito, abuso; e em sequência como uma consequência/efeito, como vergonha, medo, raiva. Verificou-se ainda que existe similaridade dos termos utilizados pelos participantes das pesquisas de 2008 até 2015.

Published: April 2019

Eating disorders is a general term used for grouping all the problems related to eating attitudes under one title and for expressing these problems. Orthorexia nervosa (ON), also known as “obsession of healthy eating” recently happened to be the research topic of clinicians worldwide. This study was conducted to evaluate the association between eating attitudes and orthorexia nervosa in university students. The research population was comprised of 379 university students in the departments of nutrition and dietetics and nursing. The data was collected by the survey form questioning some of the socio-demographic and anthropometric properties of the students; and as for the data collection tool, ON tendency was determined by ORTHO-11 test and the information regarding anorexia and buliminia nervosa was gathered by “Eating Manner Test (EAT-40). Mean age of the students was found as 20.09±1.47 years, mean body weight as 60.55±10.01 kg, and mean height as 168.08±7.91 cm. Mean BMI of the all participating students is found as 21.6±2.12 as normal weight (18.5-24.9). EAT-40 points of the female were found to be significantly higher in comparison to that of the male (p<0.05). ORTHO-11 points of the male students were found to be significantly higher as compared to that of female students (p<0.05). Eating disorders will tend to increase as long as the concepts of beauty, good look and appeal are based on low body mass index. We also believe that the youg population who are most influenced by such popular trends need to acquire truly healthy nutrition habits through training and increase their quality of life.
Nitrogen Management in Baby Corn: A Review
Authors: Singh S. P. , Neupane M. P. , Sravan U. Sai , Kumar Sandeep , Yadav Tikendra , Choudhary S. K.
Published: April 2019

Baby corn (Zea mays L.) is a short duration crop, relatively new introduction in India and a potential option for raising farmer’s income being a high value crop. This crop may open new alternatives since fits well in the cropping systems and grown year round in a wide range of climatic conditions. Production technologies of baby corn differ from maize thus, development and standardization of location specific agro-techniques are required before popularization among the farmers. Nitrogen (N) deficiency is a wide spread phenomenon in Indian soils and its proper management is of enormous significance from economic and environmental point of view. Efficient utilization depends on the right time, method and optimum N application synchronizing with the crop demands. Studies so far suggest N application in variable rates and proportions for different agro-ecological zones. Yield increases with N rates up to certain level but optimum economic N dose is found independent of plant densities. Baby corn-legume intercropping may be a viable option to improve N-fixation and system productivity. More studies needed on N management in baby corn based cropping systems. Integrated nutrient management (INM) practice should be adopted as core strategy for sustainability and reduce dependency on chemical fertilizers. Combined approach (soil application + foliar spray) enhances yield and quality in winter baby corn. Concentration and timing of urea foliar spray are two crucial factors to harness the desired benefit. Scope to harvest combined product (baby corn + green / mature cob) and its interaction with N may be explored to provide more flexibility to the farmers. Optimization of N quantities depends on season and location. Site specific nitrogen management (SSNM) approach can address the spatial and temporal variations for efficient N-management. However, cost effective and user’s friendly precision tools may be a viable option considering the real farm situations.

Published: April 2019

Aims: This paper estimates working capital management on profit using logistic regression and discriminant analysis on manufacturing and industrial firms in Ghana.

Study Design: Research Paper.

Place and Duration of Study: Ghana, Secondary data for 2009 to 2014.

Methodology: Data in the form of ratios were computed from the audited annual financial reports of 13 manufacturing and industrial firms listed on the Ghana Stock Exchange covering the period from 2009 to 2014.The ratios were used to determine the profitability of the firms.

Results: The results showed that the logistic regression of the dependent variable (Profit) on the independent variables such as the Average Collection Period, the Inventory Conversion Period, the Average Payment Period, the Growth rate, the Debt Ratio, the Current Ratio and the Company Size were found to be significant and that there was no difference in variances for two firm classifications. This result implies that the linear discriminant function is effective in discriminating between a firm which effectively managed its working capital from one which did not.

Conclusion: This study showed that the binary logistic regression model estimates correctly at least 75% of firm’s likelihood of managing working capital on profit while correctly discriminating the firms as having an effective management.

miR‐134 has been shown to be associated with angiogenesis and the progression of osteosarcoma. This study further assessed the effects of miR‐134 expression on osteosarcoma cell migration, invasion, and metastasis in vitro and in a nude mouse xenograft model, exploring the underlying molecular events. Luciferase reporter assays revealed that miR‐134 directly targets the 3′‐UTRs of MMP1 and MMP3 to reduce their expression in osteosarcoma cells. In conclusion, overexpression of miR‐134 suppresses osteosarcoma cell invasion and metastasis through the inhibition of MMP1 and MMP3 expression. We propose miR‐134 as an attractive novel therapeutic target for the treatment of osteosarcoma.

We have previously shown that secreted BAG3 is a potential target for the treatment of pancreatic ductal adenocarcinoma and that pancreatic tumor growth and metastatic dissemination can be reduced by treatment with an anti‐BAG3 murine antibody. Here, we used complementarity‐determining region (CDR) grafting to generate a humanized version of the anti‐BAG3 antibody that may be further developed for possible clinical use. We show that the humanized anti‐BAG3 antibody, named BAG3‐H2L4, abrogates BAG3 binding to macrophages and subsequent release of IL‐6. Furthermore, it specifically localizes into tumor tissues and significantly inhibits the growth of Mia PaCa‐2 pancreatic cancer cell xenografts. We propose BAG3‐H2L4 antibody as a potential clinical candidate for BAG3‐targeted therapy in pancreatic cancer.

A series of hard–soft carbon composite materials is produced from biomass and oil waste and applied as low‐cost anodes for sodium‐ion batteries to study the fundamentals behind the dependence of Na storage on their structural features. A good reversible capacity of 282 mAh g−1 is obtained at a current density of 30 mA g−1 with a high initial Coulombic efficiency of 80% at a carbonization temperature of only 1000 °C by adjusting the ratio of hard to soft carbon. The performance is superior to the pure hard or soft carbon anodes produced at the same temperatures. This synergy between hard and soft carbon resulting in an excellent performance is due to the blockage of some open pores in hard carbon by the soft carbon, which suppresses the solid electrolyte interface formation and increases the reversible sodium storage capacity.

Organic framework materials constructed by covalently linking organic building blocks into framework structures are highly regarded as paragons to precisely control the material structure at the atomic level. Herein, a direct synthesis methodology is proposed as a guidance for the bulk synthesis of organic framework materials. Framework porphyrin (POF) materials are one‐pot synthesized to demonstrate the advances of the direct synthesis methodology. The as‐synthesized POF materials are intrinsically 2D and exhibit impressive versatility in composition, structure, morphology, and function, delivering a free‐standing POF film, hybrids of POF and nanocarbon, and cobalt‐coordinated POF. When applied as electrocatalysts for oxygen reduction reaction and oxygen evolution reaction, the cobalt‐coordinated POF exhibits excellent bifunctional electrocatalytic performances comparable with noble‐metal‐based electrocatalysts. The direct synthesis methodology and resultant POF materials demonstrate the ability of controlling materials at the atomic level for energy electrocatalysis.

Hypertrophic scarring (HS) remains a great challenge in wound dressing. Although various bionic extracellular matrix (ECM) biomaterials have been designed towards HS treatment, not all biomaterials can synergize biological functions and application functions in wound repair. Bionic scar‐inhibiting scaffolds, loaded with biomolecules or drugs, become promising strategies for scarless skin regeneration. In this work, inspired by the physicochemical environment of ECM, a versatile fabrication of poly(γ‐glutamic acid) based on electrospun photocrosslinkable hydrogel fibrous scaffolds incorporated with ginsenoside Rg3 (GS‐Rg3) is developed for tissue repair and wound therapy. Decorated with adhesive peptide, bionic fibrous scaffolds can accelerate fibroblasts to sprout and grow, forming organized space‐filling basement that gradually fills a depression before wound close up in the early stage. Additionally, by sustained release of GS‐Rg3 in late stage, fibrous scaffolds promote scarless wound healing in vivo as evidenced by the promotion of cell communication and skin regeneration, as well as the subsequent decrease of angiogenesis and collagen accumulation. These ECM‐inspired fibrous scaffolds, therefore, offer new perspectives on accelerated wound healing and tissue regeneration.

Crystal phases play a key role in determining the physicochemical properties of a material. To date, many phases of transition metal dichalcogenides have been discovered, such as octahedral (1T), distorted octahedral (1T′), and trigonal prismatic (2H) phases. Among these, the 1T′ phase offers unique properties and advantages in various applications. Moreover, the 1T′ phase consists of unique zigzag chains of the transition metals, giving rise to interesting in‐plane anisotropic properties. Herein, the in‐plane optical and electrical anisotropies of metastable 1T′‐MoS2 layers are investigated by the angle‐resolved Raman spectroscopy and electrical measurements, respectively. The deconvolution of J1 and J2 peaks in the angle‐resolved Raman spectra is a key characteristic of high‐quality 1T′‐MoS2 crystal. Moreover, it is found that its electrocatalytic performance may be affected by the crystal orientation of anisotropic material due to the anisotropic charge transport.

Since the breakthrough in power conversion efficiency when perovskite materials are used in planer‐type solar cells, researchers have tried to apply perovskite materials into fiber‐shaped solar cells in order to achieve higher power conversion efficiency. However, the difficulty of film fabrication on the fiber surface makes it difficult to obtain a high‐quality perovskite film layer, and to obtain a large improvement in performance. In this work, the vapor‐assisted deposition method is creatively applied in the preparation of fiber‐shaped solar cells, and realizing the purpose of growing a high‐quality perovskite film layer on the fiber substrate after some innovative changes are made to the fabrication processes. The power conversion efficiency of the finally obtained fiber‐shaped perovskite solar cell reaches 10.79%, which is currently the highest power conversion efficiency in the field of fiber‐shaped solar cells.
Polarization Beam Splitting with Gauge Field Metamaterials

Published: April 2019

By designing a microwave metamaterial with biaxial dielectric constants, a 2D polarization‐dependent effective gauge field is experimentally realized for electromagnetic waves. Such an effective gauge field is manifested by the oppositely shifted circular dispersions for two polarizations in k‐space. A polarization beam splitter is experimentally demonstrated as an immediate application of the effective gauge field. Rather than the conventional horizontal |H〉 and vertical |V〉 basis, it allows polarization beam splitting into the |H + V〉 and |H − V〉 basis in the transmission regime and works for a large span of incidence angles, and thus provides additional degrees of freedom in optical signal processing. The implementation has proved that biaxial dielectrics can be a straightforward approach to construct gauge‐field‐driven devices and the same design principle can be further extended to the optical regime.

Published: April 2019

Photodynamic therapy (PDT) is a new treatment modality against local lesions, particularly in malignant tumors. However, higher biothiol concentrations in tumor cells will decrease the efficacy of PDT. To tackle the above challenges, a distinctive spinach‐based carbon nanomaterial called “chlorophyll‐rich biomass quantum dots” (CBQDs) with near‐infrared emission is prepared, and the CBQDs are further bound with copper ions forming CBQD‐Cu nanocomposites, which are used as a new fluorescence nanoprobe and highly efficient photosensitizer for simultaneous in vivo near‐infrared fluorescence imaging of biothiol and dual‐enhanced PDT of tumors. The mechanism of action is studied and it is shown that the binding of chlorophyll and copper ions on the surface of CBQDs reduces the energy level difference of the chlorophyll molecules, which results in an increase of reactive oxygen species (ROS) achieving enhanced PDT. On the other hand, the copper ions on the CBQD‐Cu surface can also bind with biothiol which decreases the concentration of free biothiol in tumor cells, and further enhances PDT. At the same time, the combination of copper ions and biothiol opens the fluorescence of CBQDs, which realizes near‐infrared fluorescence imaging of biothiol. Hence, the CBQD‐Cu is used as a highly effective nanomedicine for the recognition and treatment of tumors.

Published: April 2019

Stretchable micropower sources with high energy density and stability under repeated tensile deformation are key components of flexible/wearable microelectronics. Herein, through the combination of strain engineering and modulation of the interlayer spacing, freestanding and lightweight MXene/bacterial cellulose (BC) composite papers with excellent mechanical stability and a high electrochemical performance are first designed and prepared via a facile all‐solution‐based paper‐making process. Following a simple laser‐cutting kirigami patterning process, bendable, twistable, and stretchable all‐solid‐state micro‐supercapacitor arrays (MSCAs) are further fabricated. As expected, benefiting from the high‐performance MXene/BC composite electrodes and rational sectional structural design, the resulting kirigami MSCAs exhibit a high areal capacitance of 111.5 mF cm−2, and are stable upon stretching of up to 100% elongation, and in bent or twisted states. The demonstrated combination of an all‐solution‐based MXene/BC composite paper‐making method and an easily manipulated laser‐cutting kirigami patterning technique enables the fabrication of MXene‐based deformable all‐solid‐state planar MSCAs in a simple and efficient manner while achieving excellent areal performance metrics and high stretchability, making them promising micropower sources that are compatible with flexible/wearable microelectronics.

Exploring new structure prototypes and phases by material design, especially anode materials, is essential to develop high‐performance Na‐ion batteries. This study proposes a new anode, Na2Cu2.09O0.50S2, with a 1D crystal structure and outstanding Na storage performance. In view of the crystal structure of Na2Cu2.09O0.50S2, [Cu4S4] chains act as electrically conducting units enabling conductivity as high as 0.5 S cm−1. The residual Na4[CuO] chains act as ionically conducting units forming rich channels for the fast conduction of Na ions as well as maintaining the structural stability even after Na ion extraction. Additional ball milling on the as‐prepared Na2Cu2.09O0.50S2 significantly decreases its grain size, achieving a capacity of 588 mA h g−1 with a high initial Coulombic efficiency of 93% at 0.2 A g−1. Moreover, the Na2Cu2.09O0.50S2 anode demonstrates outstanding rate capability (408 mA h g−1 at 2 A g−1) and extending cyclic performance (82% of capacity retention after 400 cycles). The general structural design idea based on functional units may offer a new avenue to new electrode materials.
