AbstractThe silicon (Si) offers enormous theoretical capacity as a lithium‐ion battery (LIB) anode. However, the low charge mobility in Si particles hinders its application for high current loading. In this study, ball‐milled phosphorus‐doped Si nanoparticles encapsulated with nitrogen‐doped carbon (P−Si@N−C) are employed as an anode for LIBs. P‐doped Si nanoparticles are first obtained via ball‐milling and calcination of Si with phosphoric acid. N‐doped carbon encapsulation is then introduced via carbonization of the surfactant‐assisted polymerization of pyrrole monomer on P‐doped Si. While P dopant is required to support the stability at high current density, the encapsulation of Si particles with N‐doped carbon is influential in enhancing the overall Li+ diffusivity of the Si anode. The combined approaches improve the anode's Li+ diffusivity up to tenfold compared to the untreated anode. It leads to exceptional anode stability at a high current, retaining 87 % of its initial capacity under a large current rate of 4000 mA g−1. The full‐cell comprising P−Si@N−C anode and LiFePO4 cathode demonstrates 94 % capacity retention of its initial capacity after 100 cycles at 1 C. This study explores the effective strategies to improve Li+ diffusivity for high‐rate Si‐based anode.

Authors: Arslan Sezen 
Published: February 2024

AbstractThis study fills a major gap in English as a Foreign Language (EFL) teacher education by examining the integration of pedagogical tact (PT) in an EFL teacher education programme in Turkey. Through an in‐depth examination of the programme and semi‐structured interviews, this study investigated to what extent PT, including empathising with and motivating learners, effective classroom management, differentiated instruction and support for meaningful decision‐making, is integrated. The qualitative content analysis of the programme demonstrated that many courses in the EFL teacher education programme are consistent with aspects of PT. However, there were a few areas where the programme could be further enhanced to better include all aspects of PT. This includes offering courses on effective communication and decision‐making. The interviews conducted with 21 pre‐service EFL teachers also revealed that most of them acknowledged that the programme is based on their potential teaching needs and challenges. However, they offered suggestions to improve the programme such as adding more technology courses and practice‐based implementations. Throughout the study, recommendations are provided regarding how EFL teacher education programmes could be developed and implemented with more emphasis on PT. Hence, the study's findings have important implications for teacher education programme developers in Turkey and international contexts.

AbstractAlkaloids are natural products that occur widely in many herbal plants. Anisodamine, widely present in the Solanaceae family, is an alkaloid extracted from the roots of the Anisodus tanguticus Maxim. It is an antagonist to M‐choline receptors and exhibits diverse pharmacological effects, such as cholinolytic effect, calcium antagonist effect, anti‐oxygenation effect. Anisodamine, a prominent constituent of the tropine alkaloid family, exhibits a range of pharmacological effects akin to those of atropine and scopolamine. owing to its low toxicity and moderate efficacy in clinical to wide applications, especially for varieties of shock treatment. However, there remains a dearth of research regarding the in vivo pharmacokinetics, mechanism of action, and toxicity of anisodamine. Consequently, this paper provides a comprehensive review of the anti‐shock effects, toxicity, and pharmacokinetic characteristics of anisodamine to increase the understanding of its medicinal value, and provide reference and inspiration for the clinical application and further in‐depth research of anisodamine.

AbstractHydrogen‐bonded organic frameworks (HOFs) have been widely researched and used in industrial fields owing to their relatively low weight and high pore volume. Furthermore, HOFs with redox‐active units have recently gained attention as electrode‐active materials for energy storage devices as well as other porous organic polymers. This study focuses on N,N‐bis(2‐isophthalicacid)naphthalenediimide (ECUT‐HOF‐30), which exhibits good redox and mechanical properties owing to the redox‐active imide units in heterocyclic compounds, and 1,3,6,8‐tetrakis(4‐carboxyphenyl)pyrene (PFC‐1) and 3,3’,5,5’‐tetrakis‐(4‐carboxyphenyl)‐1,1’‐biphenyl (TCBP) without imide units as relatively lightweight HOFs. We evaluated the battery performance using three HOFs with and without redox‐active imide units as cathode active materials for rechargeable lithium‐ion and sodium‐ion batteries (LIBs and SIBs). The HOFs maintained their cycle stability and battery capacities even by HOF formation and ECUT‐HOF‐30 with redox‐active imide units particularly exhibited good battery performance. These results imply the potential of rigid HOFs with redox‐active imide units for realizing high‐performance energy storage devices.

AbstractCationic biocides play a crucial role in the disinfection of domestic and healthcare surfaces. Due to the rise of bacterial resistance towards common cationic disinfectants like quaternary ammonium compounds (QACs), the development of novel actives is necessary for effective infection prevention and control. Toward this end, a series of 15 chimeric biscationic amphiphilic compounds, bearing both ammonium and phosphonium residues, were prepared to probe the structure and efficacy of mixed cationic ammonium‐phosphonium structures. Compounds were obtained in two steps and good yields, with straightforward and chromatography‐free purifications. Antibacterial activity evaluation of these compounds against a panel of seven bacterial strains, including two MRSA strains as well as opportunistic pathogen A. baumannii, were encouraging, as low micromolar inhibitory activity was observed for multiple structures. Alkyl chain length on the ammonium group was, as expected, a major determinant of bioactivity. In addition, high therapeutic indexes (up to 125‐fold) for triphenyl phosphonium‐bearing amphiphiles were observed when comparing antimicrobial activity to mammalian cell lysis activity.

Published: February 2024

AbstractIn the current challenging energy storage and conversion landscape, solid‐state lithium metal batteries with high energy conversion efficiency, high energy density, and high safety stand out. Due to the limitations of material properties, it is difficult to achieve the ideal requirements of solid electrolytes with a single‐phase electrolyte. A composite solid electrolyte is composed of two or more different materials. Composite electrolytes can simultaneously offer the advantages of multiple materials. Through different composite methods, the merits of various materials can be incorporated into the most essential part of the battery in a specific form. Currently, more and more researchers are focusing on composite methods for combining components in composite electrolytes. The ion transport capacity, interface stability, machinability, and safety of electrolytes can be significantly improved by selecting appropriate composite methods. This review summarizes the composite methods used for the components of composite electrolytes, such as filler blending, embedded framework, and multilayer bonding. It also discusses the future development trends of all‐solid‐state lithium batteries (ASSLBs).

Published: February 2024

SummaryRectifier load in inductive power transfer system has nonlinear characteristics. However, the traditional analysis method equates it to a pure resistor, which leads to a certain deviation between the theoretical analysis and the actual circuit. This will reduce the accuracy of the inductive power transfer (IPT) system model and affect the soft switching operation of the inverter. In this paper, the IPT system with S‐type topology on the secondary side is studied. Firstly, the resistance–inductance characteristics of the rectifier load are analyzed by simulation, and then a second‐order circuit response model is established to solve the time‐domain expression of voltage and current. Then, the fundamental component of voltage and current is extracted by Fourier transform to calculate the impedance value of the rectifier load, and the mathematical calculation model of the rectifier load is established. On this basis, the influence of the inductive component of the rectifier load on the input impedance of the IPT system is analyzed. Then, a parameter design method for zero voltage switching is proposed for S‐S and LCC‐S topologies. Finally, an experimental platform of S‐S and LCC‐S IPT system is built. The correctness and effectiveness of the theoretical analysis and the proposed parameter design method are verified by experiments.

AbstractIn this paper, we have reported the synthesis of activated carbon (AC) from biomass cattail fiber through hydrothermal carbonization, followed by chemical activation, and its electrochemical capacitance and hydrogen storage properties. The AC exhibits a Brunauer‐Emmett‐Teller (BET) surface area (SBET) of 1597.5 m2g−1, determined from the low‐pressure N2 adsorption isotherm at 77 K using a BET‐multipoint plot. The AC sample shows a reversible hydrogen adsorption capacity of 0.25 wt.% H2 (1.25 mmol H2 g−1) at 293 K and 74 atm. The capacitance performance of AC was investigated with various conductive additives such as carbon nanotubes (CNTs), carbon black (CB), and reduced graphene‐oxide (rGO). From galvanostatic charge discharge (GCD) and cyclic voltammetry (CV) measurements, the as‐derived AC with polymer binder exhibits a specific capacitance (Cs) of 245.2 F g−1 at 0.2 A g−1 and 158.1 F g−1 at 5 mV s−1. Among the investigated conductive additives, AC with CNTs in KOH electrolyte exhibit highest Cs of 326 F g−1 at 0.2 A g−1 and 173 F g−1 at 5 mV s−1. Furthermore, the symmetrical two‐electrode device fabricated using AC with CNTs (as a conductive additive) in 1 M aq. Na2SO4 electrolyte shows a Cs of 97.2 F g−1 at 0.1 A g−1. The energy and power densities of the two‐electrode device were observed to be 28 kW kg−1 and 2.64 Wh kg−1, respectively.

AbstractAn economically appealing alternative to the use of fossil fuels in many nations is the electric vehicle (EV). Commercial EVs have a battery that powers the motor while also being charged by solar photovoltaic (PV). The original contribution of this research work is to implement a smart and advanced methodologies for accomplishing the objectives of MPPT control and battery management in EVs. Here, a novel spotted hyena optimized (SHO)‐MPPT controlling algorithm is applied to get the most out of the electricity generated by PV panels to meet EV energy requirements. A modified high gain super‐lift Luo converter has been implemented to improve and regulate the output voltage of PV for optimal battery charging and motor control. Then, an adaptive dynamic encoded network controller is designed to improve the voltage regulation and boosting performance of the DC‐DC converter. Consequently, a Henry gas solubility optimization is deployed to perform an effective battery management in EVs by optimally estimating the state of charge, which helps to increase the charging efficiency of EVs. Moreover, a three‐phase voltage source inverter has also been used to lower harmonic levels and deliver high‐quality output power to the EV motor. The results of the proposed MPPT controlling, converter controlling, and battery management strategies are verified in this study using a complete simulation and comparison analysis, where the parameters such as IV‐PV characteristics, motor torque, speed, total harmonic distortions (THDs), and so forth are taken into account for performance validation. By using the proposed controlling methodology, the THD is reduced to 1.09% with the improved vehicle speed of 3000 rpm, and overall performance efficiency of 99%.

Published: February 2024

AbstractAccurate wind speed prediction is of great importance for the operation of wind farms, and extensive efforts have been made to develop effective forecasting methods in this regard. However, the feature selection of data input as well as optimization of deep learning models have received comparatively less attention, leading to unreliable forecasting results. This research proposes a novel hybrid model that integrates data preprocessing, feature selection, and optimized forecasting for improved wind speed prediction. Specifically, a powerful preprocessing technique is utilized to reduce data noise disturbances, while an innovative two‐stage feature selection is designed to achieve the optimal input data format for forecasting purposes. Moreover, a hybrid forecasting module based on long‐short term memory, which is optimized by the Bayesian optimization algorithm, has been developed to enhance the efficiency and reliability of the model. The empirical study used 10‐min interval wind speed data of four seasons for presentation and evaluation results demonstrated its superior performance in effectively learning the volatility and irregularity features of wind speed series, which established a solid foundation for practical applications in wind power systems.

AbstractBackgroundAge‐related cognitive decline is linked to changes in the brain, particularly the deterioration of white matter (WM) microstructure that accelerates after the age of 60. WM deterioration is associated with mild cognitive impairment and dementia, but the origin and role of white matter signal abnormalities (WMSA) seen in standard MRI remain debated due to their heterogeneity. This study explores the potential of single‐shell 3‐tissue constrained spherical deconvolution (SS3T‐CSD), a novel technique that models diffusion data in terms of gray matter (TG), white matter (Tw), and cerebrospinal fluid (TC), to differentiate WMSA from normal‐appearing white matter and better understand the interplay between changes in WM microstructure and decline in cognition.MethodsA total of 189 individuals from the GENIC cohort were included. MRI data, including T1‐weighted and diffusion images, were obtained. Preprocessing steps were performed on the diffusion MRI data, followed by the SS3T‐CSD. WMSA were segmented using FreeSurfer. Statistical analyses were conducted to assess the association between age, WMSA volume, 3‐tissue signal fractions (Tw, TG, and TC), and neuropsychological variables.ResultsParticipants above 60 years old showed worse cognitive performance and processing speed compared to those below 60 (p < .001). Age was negatively associated with Tw in normal‐appearing white matter (p < .001) and positively associated with TG in both WMSA (p < .01) and normal‐appearing white matter (p < .001). Age was also significantly associated with WMSA volume (p < .001). Higher processing speed was associated with lower Tw and higher TG, in normal‐appearing white matter (p < .01 and p < .001, respectively), as well as increased WMSA volume (p < .001). Similarly, lower MMSE scores correlated with lower Tw and higher TG in normal‐appearing white matter (p < .05). High cholesterol and hypertension were associated with higher WMSA volume (p < .05).ConclusionThe microstructural heterogeneity within normal‐appearing white matter and WMSA is associated with increasing age and cognitive variation, in cognitively unimpaired individuals. Furthermore, the 3‐tissue signal fractions are more specific to potential white matter alterations than conventional MRI measures such as WMSA volume. These findings also support the view that the WMSA volumes may be more influenced by vascular risk factors than the 3‐tissue metrics. Finally, the 3‐tissue metrics were able to capture associations with cognitive tests and therefore capable of capturing subtle pathological changes in the brain in individuals who are still within the normal range of cognitive performance.

AbstractBackgroundMultimorbidity among older adults is a growing concern in India. Multimorbidity is defined as the coexistence of two or more chronic health conditions in an individual. Primary studies have been conducted on risk factors of multimorbidity in India, but no systematic review has been conducted on this topic. This systematic review aimed to synthesize the existing evidence on risk factors of multimorbidity among older adults in India.MethodsThe JBI and Preferred Reporting Items for Systematic Reviews and Meta‐Analysis guidelines were followed. Several databases were searched for published and unpublished studies until August 03, 2022. The screening of titles and abstracts and full texts, data extraction, and quality assessment were conducted by two independent reviewers. Any disagreements were resolved through discussion or by involving a third reviewer. Data synthesis was conducted using narrative synthesis and random effects meta‐analysis, where appropriate.ResultsOut of 8781 records identified from the literature search, 16 and 15 studies were included in the systematic review and meta‐analysis, respectively. All included studies were cross‐sectional, and 10 met a critical appraisal score of more than 70%. Broadly, sociodemographic, lifestyle, and health conditions‐related factors were explored in these studies. The pooled odds of multimorbidity were higher in people aged ≥70 years compared to 60‐69 years (odds ratio (OR) 1.51; 95% confidence interval (CI) 1.20–1.91), females compared to males (1.38; 1.09–1.75), single, divorced, separated, and widowed compared to married (1.29; 1.11–1.49), economically dependent compared to economically independent (1.54; 1.21–1.97), and smokers compared to non‐smokers (1.33; 1.16–1.52) and were lower in working compared to not working (0.51; 0.36–0.72).ConclusionThis systematic review and meta‐analysis provided a comprehensive picture of the problem by synthesizing the existing evidence on risk factors of multimorbidity among older adults in India. These synthesized sociodemographic and lifestyle factors should be taken into consideration when developing health interventions for addressing multimorbidity among older adults in India.
