Enhancement mechanism of the comprehensive performance of all-solid-state polymer electrolytes by halloysite nanotubes: Construction of efficient lithium-ion conduction channels

Considering the current issues with poly(ethylene oxide)-based all-solid-state polymer electrolytes (PEO-ASSPEs) employed in lithium-ion batteries (LIBs), such as low ionic conductivity, low lithium-ion transference number, narrow electrochemical stability window, and poor cyclic stability. This study introduces oxygen-vacancy-rich halloysite nanotubes (HNTs) and lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) into the PEO matrix to fabricate a flexible composite polymer electrolyte (CPEs) via a solvent-free method. The interaction between HNTs and LiTFSI in the PEO matrix serves to mitigate the ionic solvation effect, increase the number of free lithium-ion, and reduce the lithium-ion migration energy barrier. Additionally, the internal framework formed by the mutual stacking of HNTs reduces the number of entanglements in polymer molecular chains, enhances the mobility of the chains, and generates a continuous interface effect, forming fast lithium-ion transport channels. The CPEs prepared in this study are in conformity with the Vogel-Tammann-Fulcher (VTF) empirical equation. The CPE containing 10 wt% HNTs exhibits a high ionic conductivity (7.15 × 10−4 S cm−1) at 25 °C, a high lithium-ion transference number (0.600), a wide electrochemical stability window (5.5 V), and excellent cyclic performance (capacity retention of 82.02 % after 100 cycles at 0.1C), satisfying the electrochemical performance requirements for ASSPEs in LIBs.

Applications of Autonomous Navigation Technologies for Unmanned Agricultural Tractors: A Review

The development of unmanned agricultural tractors (UAT) represents a significant step towards intelligent agricultural equipment. UAT technology is expected to lighten the workload of laborers and enhance the accuracy and efficiency of mechanized operations. Through the investigation of 123 relevant studies in the literature published in recent years, this article reviews three aspects of autonomous navigation technologies for UATs: perception, path planning and tracking, and motion control. The advantages and deficiencies of these technologies in the context of UATs are clarified by analyzing technical principles and the status of current research. We conduct summaries and analyses of existing unmanned navigation solutions for different application scenarios in order to identify current bottleneck issues. Based on the analysis of the applicability of autonomous navigation technologies in UATs, it can be seen that fruitful research progress has been achieved. The review also summarizes the common problems seen in current UAT technologies. The application of research to the sharing and integrating of multi-source data for autonomous navigation has so far been relatively weak. There is an urgent need for high-precision and high-stability sensing equipment. The universality of path planning methods and the efficiency and precision of path tracking need to be improved, and it is also necessary to develop highly reliable electrical control modules to enhance motion control performance. Overall, advanced sensors, high-performance intelligent algorithms, and reliable electrical control hardware are key factors in promoting the development of UAT technology.

Recent Advances in Piezocatalysts for Dye Degradation

AbstractPiezocatalysis is attracting extensive attention in recent years because it can directly convert mechanical energy from the ambient environment (such as tiny vibrations and noise) into piezopotential for catalytic activities. Dyes are widely used in diverse industries, including paper, printing, and textiles, which cause serious environmental problems due to their persistence and toxicity. Unlike traditional catalysts that rely on chemical reactions to drive dye degradation, piezocatalysts offer a sustainable and cost‐effective alternative to breaking down complex molecules through creating highly reactive species, which have shown a significant promise in the treatment of organic pollutants in wastewater. In this review, the basic principles of piezocatalysis are first outlined, specifically describing two ubiquitous forms of driving force in nature. Following the catalytic mechanism, the current mainstream piezocatalytic materials are classified into two categories: organic and inorganic materials with detailed discussions. Moreover, after investigating and analyzing previous literature, effective strategies for improving piezocatalytic efficiency for dye degradation are systematically compared and summarized. In the end, current issues that need to be addressed in the future as well as potential research directions related to piezocatalysis are prospected. This work provides an insight into solving current issues to advance the piezocatalysts.

Public Health Law In Malaysia And The United States: Comparing Current Applications

Background: The main objective of public health law is to pursue the highest possible level of physical and mental health in the population, consistent with the values of social justice. Aims: To elaborate on Malaysia’s public health laws that share unique commonalities with those of the United States of America, due to both countries’ colonial past as part of the British Empire. Methods: Historical review and analysis of current public health law issues in both nations. Results: The United States of America gained full independence from the British Empire on 3 September 1783, while almost three years later, on 11 August 1786, the Union Jack was raised on the island of Pulau Pinang in Malaysia. When the colonies first formed the United States, there was no national public health law; the American colonies adopted the English laws on the control of diseases. This is similar to Pulau Pinang, after the implementation of the Charter of Justice in 1807. Conclusion: Current applications of the law, which include quarantine, sanitation, disease reporting, and vaccination,exhibit interesting similarities as well as differences between the United States and Malaysia.

BIBLIOMETRIC ANALYSIS OF THE GREATEST NUCLEAR DISASTERS: WHAT IS KNOWN SO FAR AND WHAT ARE THE PROSPECTS?

Abstract. The high potential of nuclear power to combat climate change and support sustainable development plays a critical role in achieving the goal of the Paris Agreement. Moreover, with the ever-increasing demand for electricity, it is essential to consider nuclear power as a reliable source of energy. However, it should be noted that although the risk of a radiological accident is small, it always exists, and therefore it is crucial to have a complete understanding of the management of nuclear power. Herein, we present a statistical review of nuclear accident research at Chernobyl and Fukushima Nuclear Power Plants using bibliometric analysis to identify key patterns in scientific results and current issues in accident research. More than 10,000 articles have been collected from the SCOPUS database covering the periods 1986–2022 and 2011–2022 on Chernobyl and Fukushima, respectively. The results were obtained from two perspectives: first, we identified stages through which pre- and post-accident researches have evolved, and then we analysed the spatial correlation between energy-economic performance and scientific literature for the leading productive countries. From the analysis of research trends, it was found that the number of articles increased sharply immediately after the accident and slightly decreased over time. Among the most attractive subject categories in terms of the largest number of publications and received citations were environmental sciences, medicine and energy policy. The productive country ranking was mostly topped by the country in which the accident occurred. Spatial statistical analysis revealed a strong correlation between the scientific productivity and energy-economic performance of the leading countries.

The Preacher and the King: vision and meaning in Atheniensis 211

Codex Atheniensis 211 is the earliest surviving illustrated Chrysostomic anthology. Its unique and sophisticated illustration still puzzles and fascinates scholars. The relative chronology of the manuscript fluctuates between the end of the ninth century and the first half of the tenth, while its provenance remains to this day unspecified. In an attempt to illuminate the circumstances of its creation, this study engages with the examination of a unique homily and its illustration. In my view, the people responsible for the selection of the sermon and the design of its illustration conceived it as a meaningful re-contextualization of the homily's original delivery; the historical background of fifth-century Constantinople served as a springboard for the articulation of an eloquent visual comment on current public issues in the Byzantine capital.

Deeper Than Reason

This article chronicles factors contributingto the neglect of the assessment of practical forms of knowledge in Vocational Education and Training (VET) in England. It illustrates how older, more coherent concepts of forms of knowledge, skills and competence have been pushed to the margins of educational discourse, replaced by restricted, fragmented and much less credible conceptual imposters. The consequences of these restricted conceptions and how they have subsequently become organised, taught and assessed in VET are discussed. Particular attention is given to the ways in which such restricted conceptions can lead to vocational assessment regimes which require little more than ‘one-off’ demonstrations of successful performance, expressed in behaviourist outcomes; the superficial recall of cognitive concepts; and the regurgitation of factual information in pen and paper examinations. Comparisons are drawn between the strongly centralist system of control regulating VET in England and alternative more collaborative state partnership systems of VET currently operating in Continental Europe. This small-scale, qualitative study, conducted with 12 tutors of VET in Further Education (FE) colleges and Industry Training Providers (ITPs) brings to light the impact of these restricted concepts in VET in England today. Research methods include, iterature review, transcripts of semi-structured interviews with vocational teachers and education leaders and focus group discussions. Reflexive Thematic Anlaysis (RTA) is employed to identify subthemes and themes in the data in order to identify, refine and discuss findings. Results reveal that sector practitioners require further professional development in addressing current issues in incoherent curriculum design and inauthentic approaches to assessment.

Women's career development through everyday life in post‐war Japan: Survey of the Shufuren (the Japanese Association of Consumer Organizations)

AbstractThis paper explores the career development process of women in postwar Japan who belonged to the Shufuren (the Association of Consumer Organization), the homemakers' federation, and who became experts in everyday life through studying and researching to improve their lives. It analyzes the organizational chart, hours and fundings for activities, details of activities, formation of the cooperative relationships, and career development of the leaders. The women who gathered at the Shufuren studied and researched the issues that arose in daily lives. By accumulating survey and research data and presenting scientific evidence, they made requests and proposals for improvements to the Diet, governments, and industries. Through these activities, they contributed to establish laws and systems protecting consumer rights. The women also developed partnerships with other civic groups in sharing current social issues. They expanded the circle of the movement and asserted their demands to the Diet, government agencies, industries, and the public. The members grew as experts in everyday life by steadily building their careers with passion for daily activities. Their activities were not limited to the Shufuren; some women went beyond the Shufuren to become leaders of organizations. Conventionally, homemakers are viewed as not having career development aspirations. When discussing women's career development in Japan, attention has focused on career development through work and balancing work and family life. However, the activities and steps taken by the female members of the Shufuren to improve their lives should also be considered a form of career development.
