Halide perovskite-based resistive random-access memory (ReRAM), a next-generation non-volatile memory option, has attracted a lot of attention due to the search for environmentally friendly and adaptive electronics. Recent developments in flexible ReRAM and in lead-free halide perovskite-based memory devices are compiled in this paper, with an emphasis on electrical performance, switching mechanisms, stability-enhancing techniques, and structural design. Halide perovskites' natural advantages-such as their low working voltage, fast switching speed, and solution processability-make them attractive for incorporation into flexible platforms including neuromorphic computers, wearable electronics, and implanted devices. These devices exhibit fast switching, low operating voltages (<1 V), and high ON/OFF ratios (>10⁶), making them promising for low-power applications. The operating voltages of devices that use MAPbI₃ and CsPbBr₃ are less than 1 V, and their ON/OFF ratios are greater than 10⁶. Performance deterioration brought on by mechanical deformation and exposure to the environment is still a major problem, though. Mechanical resilience and long-term retention have been improved through composite structures, interface engineering, and encapsulation strategies. There have been significant efforts to create lead-free substitutes in order to address environmental concerns regarding lead-based compounds. Even though compounds like Cs₃Bi₂I₉, Cs₂SnI₆, and Cs₂AgBiBr₆ are less toxic and more chemically stable, issues like oxidation, decreased mobility, and variability still exist. Strategies such as dimensional tuning and passivation are being explored to overcome these limitations.

However, integration scalability, switching uniformity, and environmental stability remain key challenges for future research. Halide Perovskite-based ReRAM is positioned as a viable candidate for adaptable, ecologically friendly memory applications that meet the demands of modern electronics thanks to ongoing material innovation and system-level optimization.

卤化物钙钛矿基电阻随机存取存储器（ReRAM）是下一代非易失性存储器，由于对环境友好和自适应电子器件的研究，引起了人们的广泛关注。本文综述了柔性ReRAM和基于无铅卤化物钙钛矿的存储器件的最新进展，重点介绍了电性能、开关机制、增强稳定性技术和结构设计。卤化物钙钛矿的天然优势——例如低工作电压、快速开关速度和溶液可加工性——使得它们对于集成到柔性平台（包括神经形态计算机、可穿戴电子设备和植入设备）具有吸引力。这些器件具有快速开关，低工作电压（<1 V）和高开/关比（>106），使其具有低功耗应用的前景。使用MAPbI3和CsPbBr3的器件工作电压小于1v， ON/OFF比值大于106。然而，机械变形和暴露在环境中导致的性能下降仍然是一个主要问题。通过复合结构、界面工程和封装策略，提高了材料的机械弹性和长期保持性。为了解决有关铅基化合物的环境问题，已经在创造无铅替代品方面做出了重大努力。尽管像Cs3Bi2I9、Cs2SnI6和Cs2AgBiBr6这样的化合物毒性更小，化学性质更稳定，但氧化、迁移率降低和可变性等问题仍然存在。诸如维度调整和钝化等策略正在被探索以克服这些限制。然而，集成可扩展性、开关均匀性和环境稳定性仍然是未来研究的关键挑战。基于卤化物钙钛矿的ReRAM被定位为适应性强、生态友好的内存应用的可行候选者，由于不断的材料创新和系统级优化，这些应用可以满足现代电子产品的需求。

The synthesis of cost-effective, easily synthesizable electrocatalysts for oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) is crucial for advancement in sustainable hydrogen generation. The present study presents a facile synthesis of nickel-doped carbon (Ni@C) from bio-waste by microwave-assisted method as a highly efficient and sustainable electrocatalyst for the splitting of water. Physicochemical characterisation of the synthesised electrocatalyst confirms the effective incorporation of nickel in the carbon matrix, leading to the enhancement in electrocatalytically active sites. Evaluation of electrochemical parameters in 1 M KOH displays 280 mV and 180 mV overpotentials for OER and HER at 10 mA/cm². Full cell electrolysis demonstrates the promising and excellent electrocatalytic behaviour at a potential of 1.65 V. Prolonged stability tests showed excellent durability for 100 h. The synthesised Ni@C electrocatalyst from bio-waste offers an environmentally friendly, easily synthesizable and cost-effective alternative for the production of hydrogen by water electrolysis. Integrating solar energy systems with electrolysis enables high-scale and sustainable hydrogen generation, leading towards the transformation into renewable energy technologies.

In this work, a sustainable and efficient approach was developed to address the challenges associated with the dissolution of the entire biomass lignocellulosic components. This was carried out using a deep eutectic solvent (DES) and N-methylmorpholine N-oxide (NMMO), together as a binary solvent system for direct dissolution and film fabrication of cotton gin trash (CGT) and cotton gin motes (CGM), two underutilized agricultural residues. The DES facilitated the selective dissolution of lignin and hemicellulose, while NMMO effectively dissolved crystalline cellulose. The synergistic action of DES and NMMO enabled efficient co-dissolution of lignin, hemicellulose and cellulose without fractionation. XRD and ¹³CNMR confirmed a transition from crystalline cellulose structure to a more amorphous network in the regenerated films, particularly in CGT-rich compositions. The films showed enhanced thermal stability, with the 1:1 CGT/CGM blend film exhibiting the highest onset temperature. The mechanical testing indicated that the 1:1 CGT/CGM blend films achieved an optimal balance between tensile strength and flexibility through combining CGM's crystalline cellulose reinforcement with CGT's amorphous lignin and hemicellulose content. This study demonstrates the potential of CGT and CGM as sustainable raw materials and the proposed DES/NMMO system as an effective green solvent for processing whole lignocellulosic biomass into high-value-added products.

在这项工作中，开发了一种可持续和有效的方法来解决与整个生物质木质纤维素成分溶解相关的挑战。采用深度共晶溶剂（DES）和n -甲基啉n -氧化物（NMMO）作为二元溶剂体系，对两种未充分利用的农业残留物轧棉渣（CGT）和轧棉渣（CGM）进行直接溶解和成膜。DES有利于木质素和半纤维素的选择性溶解，而NMMO则能有效溶解结晶纤维素。DES和NMMO的协同作用使木质素、半纤维素和纤维素在不分离的情况下有效共溶。XRD和13CNMR证实，再生膜从结晶纤维素结构转变为更无定形的网状结构，特别是在富含cgt的成分中。CGT/CGM共混膜表现出较高的热稳定性，其中CGT/CGM共混膜的起始温度最高。力学性能测试表明，CGM的结晶纤维素增强与CGT的无定形木质素和半纤维素含量相结合，使CGT/CGM 1:1共混膜的拉伸强度和柔韧性达到了最佳平衡。本研究证明了CGT和CGM作为可持续原料的潜力，以及所提出的DES/NMMO体系作为将整个木质纤维素生物质加工成高附加值产品的有效绿色溶剂的潜力。

The fabrication of innovative polyurethane panels for energy efficiency is increasingly important and should ideally be based on sustainable, non-fossil-based feedstock. In this context, the present work reports the development of sustainable composite panels by incorporating microencapsulated phase change materials (PCMs) into flexible polyurethane (PU) foams, synthesized from a polyol derived from waste cooking oil (WCO) and a partially bio-based isocyanate. The PU-PCM panels achieved energy storage capacity up to 26.2 J/g at a maximum PCM content of 15 phr. Uniform PCM dispersion slightly reduced cell size and increased panel density (from 128 to 157 kg/m³), thereby enhancing structural support and rigidity while reducing elasticity (compression force deflection up to 234.8 kPa). Fatigue tests confirmed resistance to cyclic loading, with increased dynamic stress and stiffness due to PCM integration. Differential scanning calorimetry showed minimal enthalpy hysteresis (±0.26 J/g) and a stable phase-change temperature (36 ± 0.1 °C), demonstrating resilience to thermal and mechanical stress. Thermal conductivity increased slightly (from 46.15 to 48.44 mW/m·K at 20 °C) due to the silica-based PCM shell, while thermal diffusivity decreased, favouring transient thermal regulation. Fire performance remained unaffected, likely due to the balance between the flammable paraffinic core and the flame-retardant silica shell of PCMs. Overall, bio-based PU-PCM panels show potential for transportation and construction applications owing to their lightweight, insulating, and flame-retardant properties. They offer improved sustainability and thermal-mechanical performance compared to conventional PU panels and flammable PCMs, while supporting circular economy principles by valorising end-of-life WCO.

为了提高能源效率，创新聚氨酯板的制造变得越来越重要，理想情况下，应该基于可持续的非化石原料。在此背景下，本工作报告了可持续复合板的发展，通过将微胶囊化相变材料（PCMs）纳入柔性聚氨酯（PU）泡沫中，由废食用油（WCO）衍生的多元醇和部分生物基异氰酸酯合成。在最大PCM含量为15 phr时，PU-PCM面板的储能容量高达26.2 J/g。均匀的PCM分散稍微减小了电池的尺寸，增加了面板密度（从128 kg/m3增加到157 kg/m3），从而增强了结构的支撑力和刚性，同时降低了弹性（压缩力挠度高达234.8 kPa）。疲劳测试证实了对循环载荷的抵抗，由于PCM集成而增加了动态应力和刚度。差示扫描量热法显示最小的焓滞（±0.26 J/g）和稳定的相变温度（36±0.1°C），显示出对热应力和机械应力的弹性。由于硅基PCM外壳的存在，导热系数略有增加（在20°C时从46.15 mW/m·K增加到48.44 mW/m·K），而热扩散率下降，有利于瞬态热调节。防火性能没有受到影响，可能是由于pcm的易燃石蜡芯和阻燃硅壳之间的平衡。总体而言，生物基PU-PCM面板由于其轻质、绝缘和阻燃特性，在运输和建筑应用中显示出潜力。与传统的PU面板和可燃pcm相比，它们提供了更好的可持续性和热机械性能，同时通过提高寿命终止的WCO来支持循环经济原则。

This work explores the use of low-value packaging film-based waste mixed plastics (wMP) and carbon nanotubes (CNT) to produce value-added composites. The performance of the composites is assessed through mechanical testing, UV ageing, and electrical conductivity measurement. Reinforcing wMP with 5 wt% CNT increased the tensile strength and tensile modulus by 46 % and 23 %, respectively. There were similar increases in flexural modulus (53 %), compressive strength (131 %), and compressive modulus (89 %) compared to unreinforced wMP. UV ageing for 500 h had no measurable effect on unreinforced wMP but decreased the flexural modulus of wMP/5 wt% CNT by 23 %. An average electrical conductivity of 1.65 × 10⁻² S/m was measured for wMP/CNT, with unreinforced wMP showing no measurable electrical conductivity, as expected. This research provides valuable scientific insights into the application of mixed waste plastics in composites, aiding the creation of a more circular economy for plastic waste and leading to second-generation products with a wide range of potential applications.

这项工作探讨了使用低价值的包装薄膜为基础的废混合塑料（wMP）和碳纳米管（CNT）来生产增值复合材料。复合材料的性能是通过机械测试、紫外线老化和电导率测量来评估的。用5 wt%碳纳米管增强wMP，拉伸强度和拉伸模量分别提高46%和23%。与未加固的wMP相比，抗弯模量（53%）、抗压强度（131%）和抗压模量（89%）也有类似的增加。紫外线老化500小时对未增强的wMP没有可测量的影响，但wMP/5 wt% CNT的弯曲模量降低了23%。wMP/CNT的平均电导率为1.65 × 10−2 S/m，未增强的wMP没有显示可测量的电导率，正如预期的那样。这项研究为混合废塑料在复合材料中的应用提供了有价值的科学见解，有助于为塑料废物创造更循环的经济，并导致具有广泛潜在应用的第二代产品。

温室气体排放导致的全球变暖加上化石燃料的有限供应是人类面临的首要问题。分解水得到氢是替代化石燃料和减少温室气体排放的最具创新性的替代方案之一。光催化水分解反应取决于半导体光催化剂吸收太阳光中的光子并产生e -和h+对的性能和效率。在开发可用于高效分解水的新型光催化剂的过程中遇到的主要挑战之一是“e -和h+对的重组”，通常称为载流子重组。在所有通过异质结形成来解决这一挑战的替代方案中，Z -方案和S -方案异质结方法显示出最有希望的结果。本文综述了Z -型和S -型异质结光催化剂的最新研究进展。此外，本文还讨论和评价了牺牲剂、缺陷工程、掺杂效应以及内建电场（BIEF）对光催化水分解的影响。本文认为，提高光催化剂的效率和稳定性是理解Z -方案和S -方案异质结中电荷转移机理以及在光催化水分解方面取得进一步进展的必要条件。

Carbon dots (CDs) are promising fluorophores for optoelectronic devices. Yet, achieving CDs with high solid-state photoluminescence quantum yields (PLQYs) remains a significant challenge. The development of metal-doped carbon dots (CDs) to effectively modulate their electronic properties and surface chemical reactivities is still in its early stages. This work introduces copper-doping to CDs (Cu-CDs) luminescent material to modify the optoelectronic properties of CDs. The as-synthesized CDs show a Stokes shift of ≈0.67 eV and high PLQYs of 62 %. The Cu-CDs show the highest power conversion efficiency of 2.36 % compared to CDs (2.04 %) with a Stokes shift of 0.71 eV. These findings demonstrate the possibility of tuning optical properties into CDs via metal doping, obtaining eco-friendly, high-efficiency LSCs through scalable production techniques, paving the way to the lab-to-fab transition of this kind of device. Our results demonstrate that dual-emission Cu-CDs with strong solid-state fluorescence are promising candidates as luminophores in efficient photovoltaic devices.

碳点（cd）是光电子器件中很有前途的荧光团。然而，实现具有高固态光致发光量子产率（PLQYs）的CDs仍然是一个重大挑战。利用金属掺杂碳点（CDs）来有效调节其电子特性和表面化学反应活性的研究仍处于早期阶段。本文将铜掺杂到CDs （Cu-CDs）发光材料中，以改变CDs的光电性能。合成的CDs显示出≈0.67 eV的Stokes位移和62%的高plqy。Cu-CDs的功率转换效率最高，为2.36%，Stokes位移为0.71 eV，高于CDs（2.04%）。这些发现证明了通过金属掺杂调整CDs光学特性的可能性，通过可扩展的生产技术获得环保、高效的LSCs，为这种设备从实验室到工厂的过渡铺平了道路。我们的研究结果表明，具有强固态荧光的双发射Cu-CDs是高效光伏器件中有前途的发光团。

Metal-organic frameworks (MOFs), with their special properties like high porosity and adjustable structures, have emerged as versatile reinforcements for nanocomposites. These hybrid systems have gained enormous attention for their potential to achieve electrical conductivity, either through the intrinsic properties of MOFs or via the incorporation of conductive nanomaterials within the MOF framework. This review explores recent advancements in nanocomposite systems reinforced with MOFs, focusing on two primary categories: systems where conductivity stems from the MOFs themselves and those enhanced by doping with additional nanomaterials. Various organic and inorganic additives, including polymer core-shells, C₃N₄, electroactive polymers, graphene, carbon (nanosheets and nanotubes), zeolites, metals, MOF-reinforced metal oxides, semimetals, and MXenes, are analyzed for their roles in enhancing the conductive, chemical, and structural characteristics of these nanocomposites. The potential of these systems to enable the development of lightweight, cost-effective, and chemically and electrically resilient materials with broad applications is also discussed. This review highlights the prospects and obstacles in advancing MOF-reinforced nanocomposites for next-generation electrically conductive materials.

金属有机骨架（mof）具有高孔隙率和可调节结构等特殊性能，已成为纳米复合材料的多功能增强材料。这些混合系统已经获得了巨大的关注，因为它们具有实现导电性的潜力，无论是通过MOF的固有特性，还是通过在MOF框架内加入导电纳米材料。本文综述了用mof增强的纳米复合材料体系的最新进展，重点关注两大类：电导率源于mof本身的体系和通过掺杂额外的纳米材料增强的体系。各种有机和无机添加剂，包括聚合物核壳、C3N4、电活性聚合物、石墨烯、碳（纳米片和纳米管）、沸石、金属、mof增强的金属氧化物、半金属和MXenes，分析了它们在增强这些纳米复合材料的导电性、化学和结构特性方面的作用。本文还讨论了这些系统在开发具有广泛应用的轻质、低成本、化学和电弹性材料方面的潜力。本文综述了mof增强纳米复合材料作为下一代导电材料的发展前景和障碍。
