Published: October 2024

A Gestão de Processos no serviço público apresenta-se como importante ferramenta para o alinhamento da gestão pública aos padrões do gerencialismo atual, possibilitando a redução de erros procedimentais, retrabalhos, tarefas repetitivas e desnecessárias, aumentando, assim, a eficiência na prestação do serviço público. O estudo objetiva verificar como a Gestão de Processos pode auxiliar na redução de inconsistências e retrabalhos na atividade de lançamento de ofício do Imposto sobre Circulação de Mercadorias e Serviços de transporte interestadual e intermunicipal e de comunicação (ICMS), executados pela Secretaria de Estado de Finanças do Estado de Rondônia - SEFIN. O estudo com finalidade aplicada, a partir de uma pesquisa descritiva, quanti-qualitativa, documental, observação participante e estudo de caso, foi realizado no âmbito da Gerência de Arrecadação, unidade que compõe a Coordenadoria da Receita Estadual (CRE), vinculada à SEFIN. A pesquisa identificou 790 lançamentos do ICMS, inscritos em dívida ativa, com inconsistências. Constatou-se que os pedidos de revisão de lançamentos inscritos em dívida ativa tratam-se de lançamentos automatizados, e as inconsistências se referem à classificação incorreta dos produtos pelo Sistema Fronteira. Verificou-se que as inconsistências podem ser reduzidas por meio de ajustes no Sistema Fronteira, de forma que as informações contidas nas notas fiscais eletrônicas sejam reconhecidas. Assim, o estudo resultou em uma proposta com 13 intervenções de ajustes na classificação automatizada do Sistema Fronteira, que reduzirá em 43,67% as inconsistências nos lançamentos de ofício do ICMS.

Published: October 2024

Non-human primates (NHPs) are considered ideal experimental models for replicating human diseases, due to their physiological, anatomical and neurological similarities to humans. However, the use of NHPs in research has ethical considerations and requires significant financial and temporal investments, due to the costs involved in the process and evaluation time. In addition to ethical issues and legal protection, research with experimental primate models involves advantages, such as the extreme physiological similarity, and disadvantages, such as the difficulty in establishing parameters for pain management and assessment. This literature review analyzed articles from the Pubmed, Scopus and Web of Science databases published in the last five years. This review included 12 articles that addressed topics such as scientific research, primate therapies, animal welfare and legal protection, highlighting the relevance of NHPs in scientific studies and interest in using these models to understand human diseases in order to develop new therapies. Despite the ethical challenges involved in this issue, it was discussed that it is important to take into account the scientific benefits and ethical considerations, as well as developing alternative methods to reduce the use of primates in research.

Authors: Arora Anjana
Published: October 2024

The socio-economic traits of farm households in Punjab's rural districts were the focus of the current study. For this objective, information was gathered from 150 farm homes from the villages of S.A.S. Nagar district, Punjab. The findings showed that the Sikh religion and General Castes comprised the majority of farm households. Most people were found to be in the 30 to 70 age range, which is the most economically active. In all farm-size categories, the sex ratio was in favour of the females. The proportion of farm households living in the joint type of family was positively associated with the farm size. Most of the persons of the marginal and small farm-size categories were illiterate and with relatively low level of education as compared to the semi-medium, medium, and large farm-size categories. The proportionate share of earners was the highest for the small farm-size category and the lowest for the semi-medium farm-size category. About 92 percent of sampled farmers owned pucca houses. The proportion of sampled farmers who owned good condition houses, bathrooms and toilets were related to the farm size. About 93% of farmers contact the local input dealers for any information needed for crop cultivation. 90 % of farmers had mobile connection. It was found that most of the farmers had an internet connection (66%) for a majority of sampled farmers in the rural areas of Punjab.
Applying Bayesian Networks for Detecting Bank Fraudulent Transactions in Nigeria
Authors: Akanbi Olawale Basheer
Published: October 2024

Bank fraud is an increasingly prevalent issue, causing substantial financial losses for both financial institutions and customers. Also, with the increasing prevalence of bank fraud, especially facilitated by online banking and digital payments, there is a pressing need for potential expertise deployment and advanced fraud detection techniques in real-world banking systems. This study specified the Bayesian Network models for detecting fraudulent bank transactions. Bayesian Networks offer a probabilistic graphical modeling approach that can effectively capture complex relationships and dependencies within financial data. Thus, the research aimed at developing a custom Bayesian network model trained on a large dataset of bank transactions comprising over one million bank transactions to classify instances as fraudulent or non-fraudulent. Python 3.11.10 was used for the graphical representations. Down-sampling was employed to reduce the dataset from its initial size of 1 million observations to 17,650 observations, ensuring a balanced representation of both fraud and non-fraud instances. Various estimation techniques:  Maximum Likelihood, Bayesian Networks, and Expectation Maximization were employed and evaluated to learn the model parameters. The model's performance was measured using metrics: accuracy, precision, recall, F1-score, and ROC-AUC. The Bayesian Networks estimator achieved an overall accuracy of 66.18%, precision of 67.73%, F1-score of 64.06%, ROC-AUC of 66.13%, Recall of 60.77%, Sensitivity of 60.77% and Specificity of 71.50%. Also, the Maximum Likelihood achieved an overall Accuracy of 66.77%, Precision of 69.22%, F1-score of 63.96%, ROC-AUC of 66.71%, Recall of 59.45%, Sensitivity of 59.45% and Specificity of 73.97%. Likewise, the Expectation Maximization achieved an overall Accuracy of 66.83%, Precision of 69.31%, F1-score of 64.00%, ROC-AUC of 66.77%, Recall of 59.45%, Sensitivity of 59.45% and Specificity of 74.09%. On the confusion matrix, the model correctly classified 1272 instances as Non-Fraudulent transactions (True Negative). Also, it was observed that the model incorrectly classified 507 instances as fraudulent transactions when they were Non-Fraudulent (False Positive). The model similarly incorrectly classified 687 instances as Non-Fraudulent transactions when they were Fraudulent (False Negative). Finally, it correctly classified 1064 instances as fraudulent transactions (True Positive). These results demonstrated the Bayesian Network's ability to identify fraudulent transactions while minimizing false alarms accurately. The findings highlight the potential of Bayesian Networks as a robust framework for fraud detection in the banking sector, contributing to enhanced security and reduced financial losses. The developed model can be introduced into existing banking systems to strengthen fraud prevention strategies.

Published: October 2024

Background: Sepsis is life-threatening organ dysfunction, and a global issue, with incidence and mortality are around 49 M cases in 2017. Annual sepsis incidence from Pakistan is around 1600-2500 per 100, 000 cases with high mortality of approx. 30%. This huge mortality among sepsis and septic shock cases from low-income settings it is necessary to implement a focused and effective triage tool to prioritize and categorize the sick patients from huge bulk of sick patients who attend the ED and to identify those who need to be seen and manage accordingly.
Emergency severity index (ESI), a widely acceptable tool that was developed to assess illness severity, hence able to identify the sick patients that need immediate attention at triage.
Objectives: Our objective is to determine the effectiveness of ESI triage acuity in early recognition of patient with sepsis and septic shock at triage in a busy ED.
Methods: This was a single center, cross sectional and observational study, we include 240 cases who present to the ED of a tertiary care hospital. We follow ESI v. 4.0. All cases presenting to the ED with suspected diagnosis of sepsis or septic shock were included.
Data was collected on a predesigned data sheet. Participants were followed by their electronic medical record number through patient care information software where patient’s medical diagnosis and discharge diagnosis are present.
Results: Total of 240 patients in the inclusion criteria, area under curve (AUC) for the ESI score I, for septic shock was 0.943 [0.921 - 0.964] with the optimal cutoff value of 2.0, sensitivity of 88.5% and specificity 100%. Similarly, the receiver operating curve (ROC) with area under the curve of ESI Score II for sepsis is found 0.2 [0.129-0.270] with sensitivity 23% and specificity was 12.7%.
Conclusion: ESI is a reliable tool which is both sensitive and specific in screening patients with septic shock in a busy emergency department.

Cluster bean is one of the significant yet underutilized leguminous vegetables belonging to family fabaceae. It is known by various names across the country such as gaur, chavli kaayi, gori kaayi, khutt, govar, and kothavare. A field experiment on cluster bean was carried out during the summer season of the year 2024 at the farm of P. L. Dodda Rangegowda in Chikkenahalli of Challakere taluk, Chitradurga district, Karnataka. The primary objectives of the study are to examine the effects of organic and inorganic fertilizers on the productivity and growth characteristics of cluster bean; to identify the advantages and disadvantages of these fertilizers in relation to productivity, soil fertility, and environment and further to review the effects of mixed organic and inorganic fertilizers on yield and soil fertility. The experiment was laid out in a randomized block design with four replications and five treatments which comprised of 100 percent organic (FYM and chicken manure), 100 percent inorganic (NPK), 50 percent organic + 50 percent inorganic, 100 percent organic + jeevamruta and control. The results revealed that, treatment T3 outperformed the others, showing the highest values for plant height, number of branches per plant, days to first flowering, days to first vegetable harvest, pod length, pod width, yield per plant, yield per plot, and yield per hectare, while the control recorded the lowest values. Soil properties such as pH, EC, SOC and NPK levels improved when combination of organic and inorganic fertilizers were applied together. Based on these results, it can be concluded that, the application of organic manures, along with chemical fertilizers, positively enhanced the vegetative growth, reproductive growth, yield, quality of cluster bean and soil parameters.

Published: October 2024

Background: Information and Communication Technologies (ICT) are fundamental for the modernization and efficiency of the public sector. The Federal University of Amazonas (UFAM) implemented an automation process in the Payments and Charges sector as of 2015, using tools such as Excel VBA and Macro Recorder, in order to optimize manual operations and increase productivity. This study evaluates the impact of automation on the efficiency of the sector, comparing data from 2014 (pre-automation) and 2018 (post-automation), in a context of significant staff reduction. Materials and Methods: The research is based on a case study, with data extracted from the reports of the Siape DataWarehouse system. The number of launches, the average time between each operation and the duration of the launches before and after the implementation of ICT were analyzed. The 2014 data reflects the manual scenario with seven servers performing the operations, while the 2018 data represents the automated scenario with three servers and technological tools optimizing the tasks. Results: The analysis showed that in 2014, the average time between manual entries was approximately 4 minutes, with 410 entries per month. In 2018, with automation, the time between launches was reduced to seconds, and the workload increased significantly, with up to 1060 monthly launches performed by just one server. Conclusion: Automation in UFAM's Payments sector resulted in a significant increase in productivity, compensating for the reduction in personnel. However, challenges such as continuous training of servers and maintenance of automated tools still need to be overcome to ensure the sustainability of long-term gains.

Authors: George Apostolou , Achilleas Papatsimpas
Published: October 2024

Background: The choices offered to students and their parents complicate the process of finding an optimal solution that meets their needs, as competition increases1 . The management of each educational organization is responsible for providing services information and curricula offered by the tutorials, as well as for designing innovative, cost-effective, and efficacious solutions2 . A learning organization with a student-oriented marketing approach is considered by many researchers as an effective mix to mixture that meets the needs of customers, students, and parents3,4. An organization with the above-mentioned features which apprehends its position, predicts the behavior of its customers, meets their needs and preferences, and enables marketing to be much more targeted and successful. As a result, it provides highvalue services, which are its comparative advantage in the market5 . The evaluation and intervention of education service providers and curriculum designers ensures the correction of errors and the adaptation to student and societal needs in all educational system processes. One of the most reliable statistical control tools of quality services and processes is the mean and standard deviation control charts6 . Both respond to the requirements of in educational processes as they are described by the normal distribution. Materials and Methods In this work, the statistical tools have been utilized to analyze the mathematics scores in the economic and scientific studies orientation of the Panhellenic exams from 2003 to 20227 . The objective of this analysis is to investigate the application of control charts as statistical methods and identify the factors responsible for any out-of-control processes. Conclusion: The study findings revealed that the modification of the curricula (all chapters of Algebra topics were removed, and only mathematical analysis topics remained) negatively affected the mean students' scores from 2015 to 2017, with a simultaneous reduction of variance. Distance education which was mandated due to the pandemic crisis did not negatively affect the mean values of the mathematics scores and increased the variance. A decrease in the number of the Panhellenic exams candidates is expected due to the demographic problem of Greece8,9. Moreover, extensive learning gaps for students who were in high school and elementary school during distance education are evident10. Finally, the service administration authorities in educational organizations and those who are responsible for the development of educational strategies should monitor student performance with the use of appropriate tools. This will help them to adapt their policies, educational tools, and curricula to the current conditions if it would be necessary

Educação Inclusiva E Neurodiversidade: Estratégias Pedagógicas Para A Inclusão De Alunos Com Distúrbios De Aprendizagem
Authors: Nascimento João Batista Do , Silva Ana Cristina Gomes , Oliveira Leandro Gilson De , Lima Odaize Do Socorro Ferreira Cavalcante , Lima Agnaldo Braga
Published: October 2024

A educação inclusiva e o conceito de neurodiversidade têm ganhado importância nas últimas décadas, destacando-se a necessidade de uma abordagem pedagógica que atenda às particularidades de alunos com distúrbios de aprendizagem, como o Transtorno do Déficit de Atenção com Hiperatividade (TDAH), dislexia, discalculia, entre outros. Este artigo discute como a formação de professores e a implementação de estratégias pedagógicas adequadas podem promover a inclusão de alunos neurodiversos nas escolas, alinhada aos princípios da educação inclusiva. A inclusão, que se baseia no direito de todos à educação de qualidade, reforça a necessidade de uma prática pedagógica que respeite as diferenças individuais e promova ambientes de aprendizagem acessíveis a todos. A neurodiversidade, que defende a ideia de que as diferenças cognitivas devem ser vistas como variações normais do desenvolvimento humano, desafia a visão tradicional de que distúrbios de aprendizagem são desvios a serem corrigidos. Em vez disso, os alunos neurodiversos necessitam de estratégias pedagógicas flexíveis e personalizadas que levem em consideração suas maneiras únicas de aprender. A adaptação curricular, o uso de tecnologias assistivas e o desenvolvimento de Planos Educacionais Individualizados (PEI) são ferramentas essenciais para garantir a inclusão escolar de alunos com necessidades educacionais especiais. No entanto, um dos grandes desafios na implementação dessas práticas inclusivas é a falta de formação docente. Muitos professores não se sentem preparados para lidar com a diversidade de estilos de aprendizagem presentes em suas salas de aula, o que pode levar à exclusão desses alunos. Pesquisas indicam que a formação continuada de professores, com foco em neurodiversidade e educação inclusiva, é uma solução fundamental para superar essa barreira. Além disso, é necessário promover uma cultura escolar que valorize a inclusão e a colaboração entre toda a comunidade escolar, incluindo professores, gestores, pais e alunos. Este artigo também explora a importância do desenvolvimento de políticas públicas que apoiem a inclusão escolar. No Brasil, a Lei Brasileira de Inclusão (LBI) e a Política Nacional de Educação Especial na Perspectiva da Educação Inclusiva são marcos legislativos que buscam garantir os direitos de alunos com deficiências ou distúrbios de aprendizagem. No entanto, a plena implementação dessas políticas ainda enfrenta desafios, como a falta de recursos e de infraestrutura adequada em muitas escolas. O objetivo deste estudo é, portanto, analisar as principais estratégias pedagógicas e políticas públicas voltadas para a inclusão de alunos neurodiversos no

Published: October 2024

A educação para a cidadania global tem ganhado relevância no cenário educacional global, principalmente no contexto da implementação dos Objetivos de Desenvolvimento Sustentável (ODS), estabelecidos pelas Nações Unidas em 2015. Esses objetivos visam promover a sustentabilidade, a igualdade e a justiça social, sendo a educação um dos principais pilares para o alcance dessas metas. A formação de professores, portanto, desempenha um papel crucial nesse processo, pois são os educadores que têm o poder de transformar as novas gerações em cidadãos globais conscientes e comprometidos com os valores do desenvolvimento sustentável. Este artigo explora a relação entre a educação para a cidadania global e a formação de professores para a implementação dos ODS. Inicialmente, o texto discute os conceitos centrais de cidadania global e ODS, mostrando como essas abordagens são complementares e essenciais para enfrentar os desafios globais contemporâneos, como a desigualdade social, as mudanças climáticas e a exclusão educacional. A educação para a cidadania global promove um entendimento das interconexões entre os países e os impactos das ações individuais e coletivas no âmbito global, o que está diretamente relacionado com os objetivos dos ODS, como erradicar a pobreza, garantir educação de qualidade e combater a mudança do clima. A formação de professores para a implementação dos ODS envolve a incorporação de novos currículos, métodos pedagógicos e ferramentas tecnológicas que incentivam a participação ativa dos estudantes. Além disso, demanda um preparo para lidar com a interdisciplinaridade dos temas abordados nos ODS, que requerem uma abordagem pedagógica inovadora, colaborativa e voltada para a solução de problemas. O artigo destaca as metodologias que estão sendo utilizadas em programas de formação de professores em diferentes partes do mundo, com foco na capacitação dos educadores para integrar a cidadania global e os ODS de maneira prática e contextualizada. Apesar dos avanços, a implementação dos ODS na educação enfrenta inúmeros desafios, como a falta de recursos, o desinteresse político em algumas regiões e a resistência de educadores a mudanças pedagógicas profundas. A desigualdade no acesso à educação de qualidade, especialmente em países em desenvolvimento, também é uma barreira significativa. Este artigo, portanto, propõe soluções para superar essas barreiras, como

Dans notre étude portant sur l’application des normes éthiques dans le métier de secrétariat de direction, il ressort que les secrétaires de direction sont conscients de leur place dans l’organisation. Néanmoins, il leur faudrait un rappel sur les normes éthiques applicables dans leur carrière. La question principale à laquelle nous avons répondu est celle de savoir comment les secrétaires de direction peuvent concilier les impératifs professionnels et les dilemmes éthiques auxquels ils sont confrontés dans l’exercice de leurs fonctions. Nous avons, à cet effet, démontré que les normes éthiques sont indispensables pour un secrétaire de direction. L’éthique professionnelle joue un rôle essentiel dans le secrétariat de direction. Elle guide les actions des professionnels, favorise la transparence des communications et renforce la responsabilité personnelle. En tant qu’assistante de direction, il est crucial de respecter les principes éthiques tels que l’écoute attentive, la courtoisie, le respect des engagements et la tolérance envers les autres. L’éthique constitue un compas moral pour prendre des décisions complexes et maintenir l’intégrité au sein de l’entreprise. Pour les directeurs de l’éthique et de la conformité, leur rôle consiste à définir des principes, les diffuser et veiller à leur adoption. En somme, l’application rigoureuse des normes d’éthique professionnelle contribue à une gestion responsable et durable du secrétariat de direction.

Published: January 2018

Decomposition of soil organic matter (SOM) in permafrost terrain and the production of greenhouse gases is a key factor for understanding climate change‐carbon feedbacks. Previous studies have shown that SOM decomposition is mostly controlled by soil temperature, soil moisture, and carbon‐nitrogen ratio (C:N). However, focus has generally been on site‐specific processes and little is known about variations in the controls on SOM decomposition across Arctic sites. For assessing SOM decomposition, we retrieved 241 samples from 101 soil profiles across three contrasting Arctic regions and incubated them in the laboratory under aerobic conditions. We assessed soil carbon losses (Closs) five times during a 1 year incubation. The incubated material consisted of near‐surface active layer (ALNS), subsurface active layer (ALSS), peat, and permafrost samples. Samples were analyzed for carbon, nitrogen, water content, δ13C, δ15N, and dry bulk density (DBD). While no significant differences were observed between total ALSS and permafrost Closs over 1 year incubation (2.3 ± 2.4% and 2.5 ± 1.5% Closs, respectively), ALNS samples showed higher Closs (7.9 ± 4.2%). DBD was the best explanatory parameter for active layer Closs across sites. Additionally, results of permafrost samples show that C:N ratio can be used to characterize initial Closs between sites. This data set on the influence of abiotic parameter on microbial SOM decomposition can improve model simulations of Arctic soil CO2 production by providing representative mean values of CO2 production rates and identifying standard parameters or proxies for upscaling potential CO2 production from site to regional scales.

Nondestructive, sublethal, and sensitive health monitoring tools are needed to assess the health of freshwater mussels (family Unionidae). Recent developments to standardize hemocyte characterization have assisted in the hematologic assessment of wild and captive freshwater mussels. In this study, preliminary baseline hematological reference ranges were established for wild mapleleaf mussels Quadrula quadrula (n = 14) and threeridge mussels Amblema plicata (n = 20) collected from the Muskingum River in Devola, Ohio. Mussels were collected from the wild, and hemolymph was sampled from each mussel in the field upon capture (baseline sample). They were then transported live to a propagation facility. Subsequent hemolymph samples were collected at 2 and 4 weeks and quarterly thereafter for 11 months following translocation. Hemocyte counts, hemocyte morphology, and hemolymph chemistry (Na+, Cl−, Mg2+, P3−, K+, Ca2+, glucose, alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase]) were measured from each sample on each sampling occasion. Hemocyte counts were consistently greater in Q. quadrula than in A. plicata following transfer to captivity. Baseline hemocyte morphology and hemolymph chemistry varied between species. This study provides a foundation of reference ranges for hemocyte characterization for Q. quadrula, and A. plicata and a preliminary understanding of how hemocyte character might be expected to change when wild mussels are translocated into captivity, and thus be a useful technique for monitoring the health of freshwater mussels.

Objective

Total knee replacement (TKR) is an effective treatment for end‐stage knee osteoarthritis (OA). American racial minorities undergo fewer TKRs than whites. We estimated quality‐adjusted life‐years (QALYs) lost for African American knee OA patients due to differences in TKR offer, acceptance, and complication rates.

Methods

We used the Osteoarthritis Policy Model, a computer simulation of knee OA, to predict QALY outcomes for African American and white knee OA patients with and without TKR. We estimated per‐person QALYs gained from TKR as the difference between QALYs with current TKR use and QALYs when no TKR was performed. We estimated average, per‐person QALY losses in African Americans as the difference between QALYs gained with white rates of TKR and QALYs gained with African American rates of TKR. We calculated population‐level QALY losses by multiplying per‐person QALY losses by the number of persons with advanced knee OA. Finally, we estimated QALYs lost specifically due to lower TKR offer and acceptance rates and higher rates of complications among African American knee OA patients.

Results

African American men and women gain 64,100 QALYs from current TKR use. With white offer and complications rates, they would gain an additional 72,000 QALYs. Because these additional gains are unrealized, we call this a loss of 72,000 QALYs. African Americans lose 67,500 QALYs because of lower offer rates, 15,800 QALYs because of lower acceptance rates, and 2,600 QALYs because of higher complication rates.

Conclusion

African Americans lose 72,000 QALYs due to disparities in TKR offer and complication rates. Programs to decrease disparities in TKR use are urgently needed.

Perovskite nanocrystals are attracting great interest due to their excellent photonic properties. Here, through a supramolecular self‐assembly approach, the perovskite nanocrystals (NCs) with a novel circularly polarized luminescence (CPL) are successfully endowed. It is found that the achiral perovskite NCs can coassemble with chiral gelator in nonpolar solvents, in which the gelator molecules modify the surface of the perovskite NCs. Through such cogelation, the molecular chirality can transfer to the NCs resulting in CPL signals with a dissymmetric factor (glum) up to 10−3. Furthermore, depending on the molecular chirality of the gelator, the CPL sense can be selected and the mirror‐imaged CPL is obtained. Such gels can be further embedded into the polymer film to facilitate flexible CPL devices. It is envisaged that this approach will afford a new insight into the designing of the functional chiroptical materials.
Large‐Grain Tin‐Rich Perovskite Films for Efficient Solar Cells via Metal Alloying Technique

Published: January 2018

Fast research progress on lead halide perovskite solar cells has been achieved in the past a few years. However, the presence of lead (Pb) in perovskite composition as a toxic element still remains a major issue for large‐scale deployment. In this work, a novel and facile technique is presented to fabricate tin (Sn)‐rich perovskite film using metal precursors and an alloying technique. Herein, the perovskite films are formed as a result of the reaction between Sn/Pb binary alloy metal precursors and methylammonium iodide (MAI) vapor in a chemical vapor deposition process carried out at 185 °C. It is found that in this approach the Pb/Sn precursors are first converted to (Pb/Sn)I2 and further reaction with MAI vapor leads to the formation of perovskite films. By using Pb–Sn eutectic alloy, perovskite films with large grain sizes up to 5 µm can be grown directly from liquid phase metal. Consequently, using an alloying technique and this unique growth mechanism, a less‐toxic and efficient perovskite solar cell with a power conversion efficiency (PCE) of 14.04% is demonstrated, while pure Sn and Pb perovskite solar cells prepared in this manner yield PCEs of 4.62% and 14.21%, respectively. It is found that this alloying technique can open up a new direction to further explore different alloy systems (binary or ternary alloys) with even lower melting point.

In this study a surfactant‐free and shape controllable preparation of microgel beads using super‐repellent surfaces is reported. The extreme hydrophobicity and the interfacial tension of the liquid force the droplet of a gel precursor solution into spherical shape on a superamphiphobic or hemisphere shape on slippery surface. During gelation on the surface, the shape is maintained. Living cells and molecules, which hardly interact with substrate, can be therefore encapsulated in situ. The encapsulation of MC3T3 mouse osteoblast is demonstrated as a proof of concept.

In this paper, a novel freestanding core‐branch negative and positive electrode material through integrating trim aligned Fe2O3 nanoneedle arrays (Fe2O3 NNAs) is first proposed with typical mesoporous structures and NiCo2O4/Ni(OH)2 hybrid nanosheet arrays (NiCo2O4/Ni(OH)2 HNAs) on SiC nanowire (SiC NW) skeletons with outstanding resistance to oxidation and corrosion, good conductivity, and large‐specific surface area. The original built SiC NWs@Fe2O3 NNAs is validated to be a highly capacitive negative electrode (721 F g−1 at 2 A g−1, i.e., 1 F cm−2 at 2.8 mA cm−2), matching well with the similarly constructed SiC NWs@NiCo2O4/Ni(OH)2 HNAs positive electrode (2580 F g−1 at 4 A g−1, i.e., 3.12 F cm−2 at 4.8 mA cm−2). Contributed by the uniquely engineered electrodes, a high‐performance asymmetric supercapacitor (ASC) is developed, which can exhibit a maximum energy density of 103 W h kg−1 at a power density of 3.5 kW kg−1, even when charging the device within 6.5 s, the energy density can still maintain as high as 45 W h kg−1 at 26.1 kW kg−1, and the ASC manifests long cycling lifespan with 86.6% capacitance retention even after 5000 cycles. This pioneering work not only offers an attractive strategy for rational construction of high‐performance SiC NW‐based nanostructured electrodes materials, but also provides a fresh route for manufacturing next‐generation high‐energy storage and conversion systems.
Simultaneous Improvement in Efficiency and Stability of Low‐Temperature‐Processed Perovskite Solar Cells by Interfacial Control

In most current state‐of‐the‐art perovskite solar cells (PSCs), high‐temperature (≈500 °C)‐sintered metal oxides are employed as electron‐transporting layers (ETLs). To lower the device processing temperature, the development of low‐temperature‐processable ETL materials (such as solution‐processed ZnO) has received growing attention. However, thus far, the use of solution‐processed ZnO is limited because the reverse decomposition reaction that occurs at ZnO/perovskite interfaces significantly degrades the charge collection and stability of PSCs. In this work, the reverse decomposition reaction is successfully retarded by sulfur passivation of solution‐processed ZnO. The sulfur passivation of ZnO by a simple chemical means, efficiently reduces the oxygen‐deficient defects and surface oxygen‐containing groups, thus effectively preventing reverse decomposition reactions during and after formation of the perovskite active layers. Using the low‐temperature‐processed sulfur‐passivated ZnO (ZnO–S), perovskite layers with higher crystallinity and larger grain size are obtained, while the charge extraction at the ZnO/perovskite interface is significantly improved. As a result, the ZnO–S‐based PSCs achieve substantially improved power‐conversion‐efficiency (PCE) (19.65%) and long‐term air‐storage stability (90% retention after 40 d) compared with pristine ZnO‐based PSCs (16.51% and 1% retention after 40 d). Notably, the PCE achieved is the highest recorded (19.65%) for low‐temperature ZnO‐based PSCs.
