With the growing demand for sustainable energy storage technologies, potassium-sulfur (K-S) batteries have attracted attention as a viable alternative to lithium-ion systems. The abundance of resources, low cost, and high energy density of potassium and sulfur make them ideal candidates for large-scale use in these types of batteries. However, challenges such as the shuttle effect, the low electrical conductivity of sulfur, and significant volume changes during electrochemical reactions pose obstacles to their practical application. Recent research efforts have focused on developing strategies to address these limitations. This study investigates the design and performance of K-S batteries employing potassium polysulfide cathodes (K₂S_n, where 2 ≤ n ≤ 4) in combination with a polymer gel electrolyte derived from cellulose modified with poly(ethylene glycol) methyl ether methacrylate (PEGMA). The primary aim is to replace conventional liquid electrolytes with this gel-based system to enhance battery efficiency, stability, and safety. This approach effectively suppresses the shuttle effect and promotes efficient K⁺ ion transport. Among the evaluated cathode materials, K₂S₃ demonstrated the highest reversible capacity (574 mAh g⁻¹ at 0.1 A g⁻¹) and superior ion diffusion characteristics. By offering a novel solution, this research highlights new directions in development of practical K-S battery technologies.

随着对可持续能源存储技术的需求不断增长，钾-硫（K-S）电池作为锂离子系统的可行替代品引起了人们的关注。钾和硫的丰富资源、低成本和高能量密度使它们成为大规模使用这些类型电池的理想选择。然而，诸如穿梭效应、硫的低电导率以及电化学反应过程中显著的体积变化等挑战阻碍了它们的实际应用。最近的研究工作集中在制定解决这些限制的策略上。本研究研究了K-S电池的设计和性能，该电池采用多硫化钾阴极（K2Sn，其中2≤n≤4）与由聚乙二醇甲基丙烯酸甲醚（PEGMA）改性的纤维素衍生的聚合物凝胶电解质相结合。主要目标是用这种凝胶基系统取代传统的液体电解质，以提高电池的效率、稳定性和安全性。这种方法有效地抑制了穿梭效应，促进了K+离子的高效输运。在评价的正极材料中，K2S3表现出最高的可逆容量（在0.1 A g−1时为574 mAh g−1）和优异的离子扩散特性。通过提供一种新颖的解决方案，本研究突出了实用K-S电池技术发展的新方向。

We developed the high performance supercapacitor device using of the MgWO₄ electrode by adding multiwall carbon nanotube (MWCNT). Here, the MWCNT-supported MgWO₄ nanocomposite was prepared through the simple hydrothermal method. The varying percentages of MWCNT addition have enhanced the electrochemical performance of MgWO₄. The prepared MgWO₄@M-5 (736 F/g) electrode exhibited an excellent specific capacitance value compared to other electrodes, including MgWO₄ (236 F/g), MgWO₄@M-0.5 (316 F/g), MgWO₄@M − 1 (522 F/g), MgWO₄@M-3 (641 F/g) and MgWO₄@M-7 (561 F/g). Moreover, the MgWO₄@M-5 electrode is utilized as the positive electrode and the activated carbon (AC) is used as the negative electrode for the construction of a pouch-type asymmetric supercapacitor device (ASC). The MgWO₄@M-5//AC ASC device shows the maximum specific capacity of 166 mAh/g. In addition, the MgWO₄@M-5//AC ASC device delivered a higher energy density of 31.12 Wh/kg with the corresponding power density of 800 W/kg. The MgWO₄@M-5//AC ASC device exhibits a capacity retention of 86.23% over 10,000 cycles. In addition, serially connecting two devices has effectively rotated the electric motor fan, and glowing the LED light is the proof of the concept of the fabricated device.

Female tea geometrid moths release sex pheromones to attract male moths to mate, and then lay eggs on tea plants, which determines where the larvae hatch. The larvae preferred to devour the fresh leaves and buds of tea plants. Therefore, it is of great significance to dynamically monitor and detect the population of the female tea geometrid moths in tea plantations. Here, different from the common strategy of detecting male moths by sex pheromone lures, we developed an electrochemical impedance biosensor system based on the pheromone-binding protein 2 (PBP2) from male tea geometrid moths. It showed that this PBP2-biosensor could specifically bind two sex pheromone components at concentrations ranging from 10⁻⁷ to 10⁻⁴ M and successfully detect live female tea geometrid moths. Molecular docking prediction pinpointed key amino acids involved in the binding between PBP2 and sex pheromone components. Moreover, a mathematical model of the biosensor detection signal was developed based on the number of live moths and the dynamic detection data. The specific PBP2-based biosensor developed in this study not only offers a novel approach for detecting live female tea geometrid moths in the field, but also contributes to the advancement of insect olfactory biosensors for monitoring live pests and further expands the applications of biosystem engineering in the fields of plant protection and agricultural environment.

雌性茶尺蛾释放性信息素吸引雄性茶尺蛾交配，然后在茶树上产卵，这决定了幼虫孵化的位置。幼虫喜欢吞食茶树的新鲜叶子和芽。因此，对茶园雌茶尺蛾种群进行动态监测和检测具有重要意义。不同于传统的性信息素引诱检测雄蛾的方法，我们基于茶蛾的信息素结合蛋白2 （PBP2）开发了一种电化学阻抗生物传感器系统。结果表明，该pbp2型生物传感器能特异性结合浓度在10−7 ~ 10−4 M范围内的两种性信息素成分，并能成功检测到茶蛾雌虫。分子对接预测确定了参与PBP2与性信息素组分结合的关键氨基酸。基于活蛾数和动态检测数据，建立了生物传感器检测信号的数学模型。本研究开发的基于pbp2的特异性生物传感器不仅为田间检测雌性茶蛾提供了一种新方法，而且有助于昆虫嗅觉生物传感器监测害虫的发展，进一步拓展生物系统工程在植物保护和农业环境领域的应用。

Semiconductors have performed remarkably since the advent of two-dimensional (2D) materials with excellent electrical, optical, and thermal characteristics. This review summarizes the recent progress made in the 2D materials field, i.e., graphene, transition metal dichalcogenides (TMDCs), and black phosphorus, focusing on their distinct thickness-dependent band structures, charge carrier mobilities, and mechanical properties. This has become a short but powerful interface for mobile devices with fast variations in our speaking circuits, and the power reaches from transistors, photodetectors, and solar cells together with digital electronics, radio-frequency devices, optoelectronics, and sensing technologies. This paper seeks to provide a clear perspective on fabrication, stability, and scale-up challenges by discussing theoretical and experimental approaches and highlighting challenges and innovative methods, including ultrasound-assisted strategies and heterostructure engineering. The present article performed and analysed a systematic literature review on key publications on the fundamental mechanisms and emerging applications of 2D materials in semiconductor technology. The review highlights the role these materials play in improving device performance, energy efficiency, and environmental friendliness. The paper concludes with a perspective on future directions, highlighting new research opportunities through advanced doping techniques and defect engineering to address current limitations and propel the broader adoption of 2D materials. This work sets another milestone for next-generation semiconductors. Another unique aspect of the study is its ability to bridge the gap between the fundamental characteristics of 2D semiconductors and real device-level integration. It draws attention to scalability, stability, and complementary metal oxide semiconductors (CMOS) compatibility difficulties that were not adequately considered in previous studies. The study discusses sophisticated tactics, including interface optimization and heterostructure engineering. A comparative analysis of 2D materials and their possible real-world semiconductor applications is also included in this chapter.

Förster resonance energy transfer (FRET) is a distance-dependent and non-radiative energy transfer process that has become a valuable tool in many fields such as biosensing, bioimaging, photovoltaics, and optoelectronics. Traditional FRET systems often used organic dyes as donors and acceptors, but these dyes have several drawbacks, including low stability, sensitivity to pH, and toxicity. To overcome these issues, researchers have started using nanomaterials of different shapes and sizes in FRET systems. This review explores the role of nanomaterials ranging from zero-to three-dimensional structures as both donors and acceptors in FRET. We discuss how their size, shape, and electronic properties affect the efficiency of energy transfer. Special attention is given to materials like quantum dots, up-conversion nanoparticles, metal nanoclusters, and perovskites. The review also summarizes different donor–acceptor pairs and their use in various applications such as detection, imaging, and solar energy harvesting. By connecting the dimensional features of nanomaterials with their performance, this review provides an overview of current research and future possibilities for FRET-based technologies.

Förster共振能量传递（FRET）是一种距离依赖和非辐射能量传递过程，已成为许多领域的宝贵工具，如生物传感，生物成像，光伏和光电子学。传统的FRET系统通常使用有机染料作为供体和受体，但这些染料有几个缺点，包括低稳定性，对pH值敏感和毒性。为了克服这些问题，研究人员已经开始在FRET系统中使用不同形状和尺寸的纳米材料。这篇综述探讨了纳米材料从零到三维结构作为供体和受体在FRET中的作用。我们讨论了它们的大小、形状和电子性质如何影响能量传递效率。特别关注量子点、上转换纳米粒子、金属纳米团簇和钙钛矿等材料。综述还总结了不同的供体-受体对及其在检测、成像和太阳能收集等各种应用中的应用。通过将纳米材料的尺寸特征与其性能联系起来，本文综述了基于fret的技术的当前研究和未来可能性。

This study proposes a two-phase decision-making framework to evaluate the calorific efficiencies of wood and bark samples obtained from the trunks and branches of fifteen hardwood tree species. The proposed framework integrates the data envelopment analysis (DEA) with the analytic hierarchy process (AHP). The DEA method is used to perform pairwise comparisons of the wood and bark samples. Ash content, volatile matter content, and fixed carbon content are selected as inputs, while the calorific value is used as the output. The results from the DEA analysis are analyzed using the AHP method to determine precise efficiency ranking indexes. The ranking order of the trunk wood samples is determined as follows: beech, oak, eucalyptus, hophornbeam, hazelnut, poplar, alder, maple, rhododendron, elm, ash, hornbeam, chestnut, linden, and plane. The ranking of the branch wood samples in descending order with the respective DEA-AHP scores is beech, poplar, alder, hophornbeam, oak, hornbeam, ash, rhododendron, eucalyptus, maple, linden, chestnut, plane, elm, and hazelnut. The sequence of the trunk bark samples is poplar, hornbeam, beech, chestnut, ash, alder, rhododendron, linden, hazelnut, maple, hophornbeam, oak, plane, elm, and eucalyptus. Lastly, the priority order of the branch bark samples is as follows: rhododendron, poplar, beech, linden, hornbeam, hazelnut, chestnut, hophornbeam, ash, alder, maple, oak, elm, plane, and eucalyptus. Additionally, comparative and sensitivity analyses are conducted to shed light on efficiency changes between the samples. The proposed framework can be used as a technical reference for selecting the most efficient materials and determining the effects of different input values on efficiency levels.

本研究提出了一个两阶段的决策框架，以评估从15种硬木树种的树干和树枝中获得的木材和树皮样品的热效率。该框架将数据包络分析（DEA）与层次分析法（AHP）相结合。采用DEA方法对木材和树皮样本进行两两比较。选择灰分含量、挥发物含量、固定碳含量作为输入，热值作为输出。采用层次分析法对DEA分析结果进行分析，确定精确的效率排序指标。树干木材样品的排序顺序确定为：山毛榉、橡树、桉树、hopnhorn、榛子、杨树、桤木、枫木、杜鹃花、榆树、白蜡树、角木、栗树、椴树、板栗。各枝材样本的DEA-AHP得分由高到低依次为山毛榉、杨树、桤木、hopnhoram、橡树、角木、白蜡树、杜鹃花、桉树、枫、椴树、板栗、板栗、榆树和榛子。树干树皮样本的顺序是杨树、角树、山毛榉、栗树、白蜡树、桤木、杜鹃花、菩提树、榛子、枫树、hophornbeam、橡树、飞机、榆树和桉树。最后，树枝树皮样品的优先级顺序为：杜鹃花、杨树、山毛榉、菩提树、角树、榛子、栗子、hophornbeam、白蜡树、桤木、枫木、橡树、榆树、飞机、桉树。此外，还进行了对比分析和敏感性分析，以揭示样品之间的效率变化。所提出的框架可作为选择最有效材料和确定不同投入值对效率水平的影响的技术参考。

The results from the DEA analysis are analyzed using the AHP method to determine precise efficiency ranking indexes. The ranking order of the trunk wood samples is determined as follows: beech, oak, eucalyptus, hophornbeam, hazelnut, poplar, alder, maple, rhododendron, elm, ash, hornbeam, chestnut, linden, and plane. The ranking of the branch wood samples in descending order with the respective DEA-AHP scores is beech, poplar, alder, hophornbeam, oak, hornbeam, ash, rhododendron, eucalyptus, maple, linden, chestnut, plane, elm, and hazelnut. The sequence of the trunk bark samples is poplar, hornbeam, beech, chestnut, ash, alder, rhododendron, linden, hazelnut, maple, hophornbeam, oak, plane, elm, and eucalyptus. Lastly, the priority order of the branch bark samples is as follows: rhododendron, poplar, beech, linden, hornbeam, hazelnut, chestnut, hophornbeam, ash, alder, maple, oak, elm, plane, and eucalyptus. Additionally, comparative and sensitivity analyses are conducted to shed light on efficiency changes between the samples. The proposed framework can be used as a technical reference for selecting the most efficient materials and determining the effects of different input values on efficiency levels.</div></div>","PeriodicalId":100036,"journal":{"name":"Advanced Sensor and Energy Materials","volume":"4 3","pages":"Article 100152"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144932003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The “Von Neumann bottleneck” of traditional computing architecture limits the speed of information processing and the physical size limit indicates the end of “More's Law”. Neuromorphic computing, a new computing architecture, is proposed to deal with the challenges. Memristors are potential in analogues of synapses and in neuromorphic computing. A synaptic device based on Au/CsPbI_3-xBr_x/GaAs memristor is fabricated. Typical synaptic plasticity of the synaptic device is investigated, including long-term potentiation (LTP), long-term depression (LTD) and paired-pulse facilitation (PPF) and the synaptic weight of the synaptic device is modulated by ultraviolet and completed the transition from short-term plasticity to long-term plasticity. Under the joint modulation of optical and electrical signals, the biological classical conditioned reflex of Pavlov's condition was achieved, proving that the device can perform associative learning. Furthermore, two artificial neural networks are constructed for modified National Institute of Standards and Technology (MNIST) data-set recognition to compare the accuracy of a single layer network and convolutional neural network (CNN).

With the advancement of hierarchical diagnosis and treatment systems, there is an increasing demand for rapid, user-friendly, and cost-effective approaches for disease analysis and prognosis monitoring. MicroRNAs (miRNAs), as vital biomarkers for early-stage disease diagnosis, pose substantial analytical challenges due to their small molecular size, low endogenous abundance, and high sequence homology among different species. Traditional methods such as Northern blotting and real-time polymerase chain reaction (RT-PCR) are limited by their complexity, lengthy procedures, and reliance on specialized instruments, making them less suitable for point-of-care (POC) applications. To address these challenges, we propose a portable and efficient POC analytical platform by utilizing a G4 catalytic network triggered by miRNA-155 through hybridization chain reaction (HCR)-mediated hydrogel assembly. A highly sensitive analysis was achieved for concentrations of 500 pM and 100 nM, with a limit of detection (LOD) of 138 pM, which demonstrated the method's capability for precise detection at low concentrations. Additionally, based on the color development reaction, its image information via RGB analysis could be used to achieve ternary precise quantitative analysis, thereby improving the analysis sensitivity and portability. This innovative platform provides a simple, cost-effective, and customizable solution for miRNA detection, opening new avenues for home-based bioanalysis and early disease diagnosis in resource-limited or remote settings.

随着分级诊断和治疗系统的发展，人们对快速、用户友好、成本效益高的疾病分析和预后监测方法的需求日益增加。MicroRNAs （miRNAs）作为早期疾病诊断的重要生物标志物，由于其小分子大小、低内源丰度和不同物种之间的高序列同源性，给分析带来了巨大挑战。传统的方法，如Northern印迹和实时聚合酶链反应（RT-PCR），由于其复杂性、冗长的程序和对专用仪器的依赖而受到限制，使其不太适合护理点（POC）应用。为了解决这些问题，我们提出了一种便携式高效的POC分析平台，该平台利用miRNA-155通过杂交链反应（HCR）介导的水凝胶组装触发的G4催化网络。在500 pM和100 nM的浓度下获得了高灵敏度分析，检测限（LOD）为138 pM，证明了该方法在低浓度下的精确检测能力。此外，基于显色反应，通过RGB分析，其图像信息可用于三元精确定量分析，从而提高分析灵敏度和便携性。这一创新平台为miRNA检测提供了一种简单、经济、可定制的解决方案，为资源有限或偏远地区的家庭生物分析和早期疾病诊断开辟了新的途径。
