Construction of Zinc‐based Anodes for Electrolytic Zinc‐MnO2 Batteries with High Discharge Voltage and Good Durability
Authors: Yang Lexuan , Meng Lijun , Ji Xu , Cheng Shuang 
Published: May 2023

AbstractRechargeable aqueous zinc‐MnO2 batteries have attracted great attention owing to their advantages on safety, power density, and cost. In strong acidic environment, the capacity of MnO2‐based cathode can reach 616 mAh g−1 through a two‐electrons‐transfer process of Mn2+↔MnO2. However, in acidic environment, Zn corrosion, dendrites, and hydrogen evolution reaction (HER) on the anode are rather serious, resulting in low Columbic efficiency (CE) and poor durability. Towards these issues, ZnO with dual‐protection, including C and polyvinyl alcohol (PVA) coating (ZnO@C‐PVA), is developed as initial anode material herein. Compared with bare CC, ZnO, and ZnO@C, reversibility of the ZnO@C‐PVA electrode is largely enhanced. CE of an electrolytic full system using ZnO@C‐PVA as anode and bare carbon cloth (CC) as cathode can be as high as 90 % at 5 mA cm−2, and discharge voltage is up to 1.85 V (mid‐value), which can be maintained for 1,600 cycles, indicating rather good stability. It is believed that the existence of initial ZnO can tune the local pH around the anode, resulting in the decrease of HER and the enhancement of Zn plating. Besides, corrosion and Zn dendrites also can be inhibited effectively by the PVA layer.

AbstractDoctors and teachers in their first year of practice face steep learning curves and increased stress, which can induce poor mental health, burnout and attrition. Informal workplace support from colleagues can help smooth transitions and aid professional development. A three‐phase comparative research design was used to explore who provides informal workplace support to early‐career professionals, types of support and influencing factors. Phase 1 was a systematic secondary analysis of interviews and audio diaries from 52 UK doctors in their first year of foundation training (F1s). Phase 2 involved new narrative interviews with 11 newly qualified teachers (NQTs) from English secondary schools. Phase 3 was a comparative analysis to produce a model of workplace support. Given barriers to accessing senior doctors, F1 doctors drew upon nurses, pharmacists, microbiologists, peers/near‐peers and allied healthcare professionals for support. NQTs gained support from allocated mentors and seniors within subject departments, as well as teaching assistants, allied support staff and wider professional networks. Support types for both professions included information and advice on practice, orientation to local settings, collaborative development activities, observation and feedback, and socioemotional support. Influencing factors included variable departmental cultures, limited opportunities for informal contact, sometimes negative inter‐group perceptions and the agentic responses of novices. The resulting workplace model of support could underpin future research and evaluations of support in similar ‘hot‐action’ environments. In medicine and teaching, greater utilisation of near‐peers and allied staff, improved role understanding and communication, increased informal contact and sharing successful strategies across professions could enhance supportive relationships.

AbstractThe realization that soluble factors secreted by heterotypic cells play an importanta role in paracrine signaling, which facilitates intercellular communication, enabled the development of physiologically relevant co‐culture models for drug screening and the engineering of tissues, such as hepatic tissues. The most crucial issues confronting the use of conventional membrane inserts in segregated co‐culture models that are used to study paracrine signaling between heterotypic cells have been identified as long‐term viability and retention of cell‐specific functions, especially when isolated primary cells are used. Herein, we present an in vitro segregated co‐culture model consisting of a well plate incubated with rat primary hepatocytes and normal human dermal fibroblasts which were segregated using a membrane insert with silica nonwoven fabric (SNF) on it. SNF, which mimics a physiological environment much more effectively than a two‐dimensional (2D) one, promotes cell differentiation and resultant paracrine signaling in a manner that is not possible in a conventional 2D culture, owing to high mechanical strength generated by its inorganic materials and interconnected network structure. In segregated co‐cultures, SNF clearly enhanced the functions of hepatocytes and fibroblasts, thereby showing its potential as a measure of paracrine signaling. These results may advance the understanding of the role played by paracrine signaling in cell‐to‐cell communication and provide novel insights into the applications of drug metabolism, tissue repair, and regeneration.

Published: May 2023

AbstractResearch has shown that spatial perception is not only one of the essential abilities for success in science, technology, engineering, and mathematics (STEM), but is also closely related to the quality of human existence. However, for a variety of reasons, many students' spatial skills are less than ideal. In recent years, various video games are showing great potential as low‐cost but effective training tools to improve the educational level and cognitive skills. This paper presented a novel serious strategy game named Magic World. The game was designed to enhance children's spatial perception and motivation by using narrative, virtual contexts, and game mechanics that incorporate educational content with entertainment as a powerful extra‐curricular aid. A pilot study and evaluation experiment were conducted with primary school students (N = 68) and the results showed that the training had a measurable positive impact on students' spatial ability. In addition, user experience surveys of the game showed that Magic World was considered a fun, challenging, and popular game for children.

Published: May 2023

AbstractThis study describes a case of a 20‐day‐old male fighting bull with bilateral clinical anophthalmia and brachygnathia superior whose dam was 12.5 years old and was mistakenly dewormed with ivermectin intramuscularly in the first third of gestation in a livestock farm. A macroscopic examination of the carcass was performed, with a special focus on the ocular components. Eyeball remains were found in both orbits and a histopathological examination was performed on them. Antibodies by serological study against bovine herpes virus‐1, respiratory syncytial virus and bovine viral diarrhea virus for both the cow and the calf were not detected. The calf had small orbits and inside them a white and brown mass of soft consistency. Microscopically, abundant muscular and adipose tissue was observed, alongside nervous structures and vestiges of ocular structures with stratified epithelium and abundant connective tissue with glands. No evidence that this congenital bilateral anophthalmia had infectious or hereditary origin was found. By contrast, the malformation could be related to the treatment with ivermectin during the first month of gestation.
Stepwise Stimuli‐Responsive, Multicolor‐Chromic Perylene Bisimide/Polyvinyl Alcohol Co‐assembly System for Information Encryption
Authors: Feng Yechang , Ma Zetong , Zhong Shilong , Wang Cheng , Chen Xudong 
Published: May 2023

AbstractThe issue of information security has become a concern in all aspects of daily life, prompting the development of encryption technologies. Therein, optical encryption using color/graphical patterns holds great potential. However, current approaches generally rely on monochromic change upon one or more stimuli, limiting their further application in advanced confidential encryption. Herein, we propose a delicate strategy based on a co‐assembly system of perylene bisimides (PBI)/polyvinyl alcohol (PVA) that demonstrates stepwise stimuli response and multicolor changes. The color of the supramolecular system changes from red to purple under the stimulus of UV light, and to orange when exposed to water. The multidimensional chromic response is achieved by an evolution process including the generation, packing rearrangement and quenching of PBI radical anions/dianions. With the virtues of photo‐ and hydrochromism, this novel co‐assembly system was successfully employed for advanced anticounterfeiting and versatile information encryption applications.

AbstractOxonitridophosphates exhibit the potential for broad structural diversity, making them promising host‐compounds in phosphor‐converted light‐emitting diode applications. The novel monophyllo‐oxonitridophosphate β‐MgSrP3N5O2was obtained by using the high‐pressure multianvil technique. The crystal structure was solved and refined based on single‐crystal X‐ray diffraction data and confirmed by powder X‐ray diffraction. β‐MgSrP3N5O2crystallizes in the orthorhombic space groupCmme(no. 67,a=8.8109(6),b=12.8096(6),c=4.9065(3) Å,Z=4) and has a structure related to that of Ba2CuSi2O7. DFT calculations were performed to investigate the phase transition from α‐ to β‐MgSrP3N5O2and to confirm the latter as the corresponding high‐pressure polymorph. Furthermore, the luminescence properties of Eu2+doped samples of both polymorphs were investigated and discussed, showing blue and cyan emission, respectively (α‐MgSrP3N5O2;λmax=438 nm,fwhm=46 nm/2396 cm−1; β‐MgSrP3N5O2;λmax=502 nm,fwhm=42 nm/1670 cm−1).

Published: May 2023

AbstractA solid polymer electrolyte has been developed and employed in lithium‐metal batteries of relevant interest. The material includes crystalline poly(ethylene glycol)dimethyl ether (PEGDME), LiTFSI and LiNO3 salts, and a SiO2 ceramic filler. The electrolyte shows ionic conductivity more than 10−4 S cm−1 at room temperature and approaching 10−3 S cm−1 at 60 °C, a Li+‐transference number exceeding 0.3, electrochemical stability from 0 to 4.4 V vs. Li+/Li, lithium stripping/deposition overvoltage below 0.08 V, and electrode/electrolyte interphase resistance of 400 Ω. Thermogravimetry indicates that the electrolyte stands up to 200 °C without significant weight loss, while FTIR spectroscopy suggests that the LiTFSI conducting salt dissolves in the polymer. The electrolyte is used in solid‐state cells with various cathodes, including LiFePO4 olivine exploiting the Li‐insertion, sulfur–carbon composite operating through Li conversion, and an oxygen electrode in which reduction and evolution reactions (i. e., ORR/OER) evolve on a carbon‐coated gas diffusion layer (GDL). The cells operate reversibly at room temperature with a capacity of 140 mA h g−1 at 3.4 V for LiFePO4, 400 mA h g−1 at 2 V for sulfur electrode, and 500 mA h g−1 at 2.5 V for oxygen. The results suggest that the electrolyte could be applied in room‐temperature solid polymer cells.

AbstractSub‐nanometer metal clusters have special physical and chemical properties, significantly different from those of nanoparticles. However, there is a major concern about their thermal stability and susceptibility to oxidation. In situ X‐ray Absorption spectroscopy and Near Ambient Pressure X‐ray Photoelectron spectroscopy results reveal that supported Cu5 clusters are resistant to irreversible oxidation at least up to 773 K, even in the presence of 0.15 mbar of oxygen. These experimental findings can be formally described by a theoretical model which combines dispersion‐corrected DFT and first principles thermochemistry revealing that most of the adsorbed O2 molecules are transformed into superoxo and peroxo species by an interplay of collective charge transfer within the network of Cu atoms and large amplitude “breathing” motions. A chemical phase diagram for Cu oxidation states of the Cu5‐oxygen system is presented, clearly different from the already known bulk and nano‐structured chemistry of Cu.

AbstractBackgroundThe quality of life (QoL) of a cancer patient is their perception of their physical, functional, psychological, and social well‐being. QoL is one of the most important factors to consider when treating someone with cancer and during follow‐up. The aim of this study was to understand the state of QoL among cancer patients in Bangladesh and to determine the factors that affect it.MethodsThis cross‐sectional study was conducted on 210 cancer patients who attended the oncology unit of Delta Medical College & Hospital, Dhaka during the period between 1 May 2022 and 31 August 2022. Data were collected using the Bengali version of the European Organization for Research and Treatment of Cancer (EORTC) questionnaire.ResultsThe study reported a high number of female cancer patients (67.6%), who were married, Muslims by religion, and non‐residents of Dhaka. Breast cancer was more common among women (31.43%), while lung and upper respiratory tract cancer was more prevalent among men (19.05%). The majority of the patients (86.19%) were diagnosed with cancer in the past year. The overall mean score for functional scales was higher for physical functioning (54.92) whereas it was lower for social functioning (38.89). The highest score on the symptom scale was for financial problems (63.02), while the lowest was for diarrhea (33.01). The overall QoL score of cancer patients in the study was 47.98 and it was lower for males (45.71) compared to females (49.10).ConclusionsThe overall QoL was poor among Bangladeshi cancer patients compared to those in developed countries. A low QoL score was observed for social and emotional functions. Financial difficulty was the main reason behind the lower QoL score on the symptom scale.
A virtuous circle brought about by corporate social responsibility – A study of the dynamic relationship between social capital, social responsibility and corporate value
Authors: Mengke Zhang , Yan Huang , Yifan Jin 
Published: May 2023

AbstractCorporate social responsibility plays an important role in promoting national harmony and high‐quality development. And social capital is the foundation of corporate survival and enhancing value is the goal of corporate survival. The interaction between social responsibility, social capital and corporate value and the degree of influence is an issue waiting to be studied. This paper takes listed companies from 2010 to 2020 as the research object, and empirically examines the dynamic interrelationship and degree of influence between the three on time series by constructing the PVAR model to include the three in the same analytical framework. The study shows that: (1) There is a virtuous circle mechanism of “social responsibility‐social capital‐corporate value”. (2) CSR and social responsibility are mutually causal, and social responsibility and corporate value are mutually causal, while social capital can only enhance corporate value in one direction. (3) Although the interaction between the three variables gradually decreases and tends to zero over time, it still has a strong lag, and the effect generated in the current period can lag at least 10 periods. The research results enrich the dynamic relationship between social capital, social responsibility and corporate value, and provide strategic references for corporate value enhancement.
mAKAPβ signalosome: A potential target for cardiac hypertrophy
Authors: Golatkar Vaishnavi , Bhatt Lokesh K. 
Published: May 2023

AbstractPathological cardiac hypertrophy is the result of a prolonged increase in the workload of the heart that activates various signaling pathways such as MAPK pathway, PKA‐dependent cAMP signaling, and CaN‐NFAT signaling pathway which further activates genes for cardiac remodeling. Various signalosomes are present in the heart that regulates the signaling of physiological and pathological cardiac hypertrophy. mAKAPβ is one such scaffold protein that regulates signaling pathways involved in promoting cardiac hypertrophy. It is present in the outer nuclear envelope of the cardiomyocytes, which provides specificity of the target toward the heart. In addition, nuclear translocation of signaling components and transcription factors such as MEF2D, NFATc, and HIF‐1α is facilitated due to the localization of mAKAPβ near the nuclear envelope. These factors are required for activation of genes promoting cardiac remodeling. Downregulation of mAKAPβ improves cardiac function and attenuates cardiac hypertrophy which in turn prevents the development of heart failure. Unlike earlier therapies for heart failure, knockout or silencing of mAKAPβ is not associated with side effects because of its high specificity in the striated myocytes. Downregulating expression of mAKAPβ is a favorable therapeutic approach toward attenuating cardiac hypertrophy and hence preventing heart failure. This review discusses mAKAPβ signalosome as a potential target for cardiac hypertrophy intervention.
Safety analysis of Sormeh underground mine to improve sublevel stoping stability

Published: May 2023

AbstractIn underground mines, sublevel stoping is used among a variety of different methods for mining an orebody, which creates large underground openings. In this case, the stability of these openings is affected by a number of factors, including the geometrical characteristics of the rock and mining‐induced stresses. In this study, a sensitivity analysis was conducted with the numerical, squat pillar, and Mathews stability methods using the Taguchi technique to properly understand the influence of geometric parameters and stress on stope stability according to Sormeh underground mine data. The results show a full factorial analysis is more reliable since stope stability is a complex process. Furthermore, the numerical results indicate that overburden stress has the most impact on stope stability, followed by stope height. However, the results obtained with Mathews and squat pillar methods show that stope height has the greatest impact, followed by overburden stress and span. It appears that these methods overestimate the impact of stope height. Therefore, it is highly recommended that Mathews and squat pillar methods should not be used in high stope that is divided with several sill pillars. Nonetheless, Mathews method cannot accurately predict how the sill pillar impacts the stope stability. In addition, numerical analysis shows that all geometric parameters affect the roof safety factor, whereas the sill pillar has no significant influence on the safety factor of the hanging wall, which is primarily determined by the stope height–span ratio.

AbstractRestoration of forests is now considered an essential tool to combat climate change and the global biodiversity decline. However, our understanding of how animal communities recover after restoration interventions in tropical forests is limited. Here, we aim to reveal the recovery patterns of fruit‐feeding butterfly communities across a large‐scale rainforest restoration area in Kibale National Park, Uganda. Our study represents a chronosequence resampling of fruit‐feeding butterfly communities across actively restored Afrotropical forest planted between 1995 and 2011 and primary forest reference sites. Sampling of 40 study sites was done first in the period 2011–2012 and again in the period 2020–2021 (including 5 new study sites), allowing a direct comparison of how communities have changed in nine years and to follow the progress of 26 years of active restoration. Fruit‐feeding butterfly community composition showed a directional pattern from the younger restored to older restored and primary forests. However, over the nine years, the similarity of community composition to primary forest increased only in younger restored forests. Furthermore, different characteristics of community structure and different diversity facets recovered at different paces. For example, the count of individuals, the count of species, and phylogenetic diversity increased in the restored forests; however, Simpson's diversity increased only in the older restored forest. Our study shows that active restoration can help fruit‐feeding butterfly communities become increasingly similar to communities found in primary forests, and such changes can be relatively fast in the early‐successional phases of tropical forests but slow down at later phases.
