Over the past three decades, significant efforts have been dedicated to developing polymeric materials with exciting healable ability; however, stiff and healable plastics with high glass transition temperatures (Tg) have received relatively less attention compared to their soft counterparts such as gels and elastomers due to the inherent trade-off between mechanical robustness and dynamics. High-performance plastics are irreplaceable in the fields of engineering and industry, making it a challenging yet urgent task to confer them with desired healable properties whilst maintaining high mechanical strength. In this review, we first present recent advances in the field of high-performance healable plastics based on constitutional dynamic chemistry, from the perspective of different topological structures including linear-, branched- and network types. Meanwhile, we also elaborate on various toughening strategies for existing healable plastics, mainly centered around molecular to micrometer scale modifications. Moreover, we also provide a detailed exposition of previous reports on the autonomously room-temperature self-healing plastics, which represent a groundbreaking development in the realm of advanced healable plastics. Eventually, we emphasize diverse functionalized healable plastics to illustrate their potential for practical implementation, and propose an outlook on the future development of healable plastics.

在过去的三十年里,人们做出了巨大的努力,致力于开发具有令人兴奋的可治愈性的聚合物材料;然而,由于机械稳健性和动力学之间的内在权衡,与凝胶和弹性体等软质塑料相比,具有高玻璃化转变温度(Tg)的刚性和可愈合塑料受到的关注相对较少。高性能塑料在工程和工业领域是不可替代的,因此在保持高机械强度的同时赋予它们所需的可治愈性能是一项具有挑战性但又紧迫的任务。本文首先介绍了基于本构动态化学的高性能可愈合塑料领域的最新进展,从不同拓扑结构的角度,包括线性型、支链型和网状型。同时,我们还详细阐述了现有可愈合塑料的各种增韧策略,主要集中在分子到微米尺度的改性上。此外,我们还详细介绍了以前关于自主室温自愈合塑料的报道,这代表了先进可愈合塑料领域的突破性发展。最后,我们强调了多种功能化的可治疗性塑料,以说明它们在实际应用中的潜力,并对可治疗性塑料的未来发展提出了展望。

Abstract In the present study, we produced SiO x /C from rice husk by the NaCl sub‐micron crystal‐assisted synthesis method which can mitigate environmental degradation and hazards, simplify preparation, and improve electrochemical performance. During synthesis, NaCl induces catalytic graphitization, carbon activation, and amorphous silica formation. Moreover, it is only partially consumed and can be recrystallized and reused indefinitely. Our NaCl sub‐micron crystal powder‐assisted method created lithium‐ion batteries (LIBs) with rice husk‐derived SiO x /C anodes that exhibited a high initial charge/discharge capacity of 422.05/915.93 mAh∙g −1 at 0.05 A∙g −1 current density and stable cycling performance. In addition, the SiO x /C electrode produced by the NaCl micro‐crystal method had 333.96 mAh∙g −1 capacity at 0.05 A∙g −1 current density. By contrast, bare rice husk electrode exhibited a lower capacity of 333.96 mAh∙g −1 at the same condition. image

To meet the requirements of power grid operation control, constructing an extensive sensor network in the power grid is a future development trend. However, due to the high cost, the difficulty of continuous power supply for a long time, the large amount of energy consumption, and the environmental problems caused by abandoned batteries, the traditional power supply mode based on batteries for sensors is inconsistent with China's goal of carbon peak and carbon neutrality. It cannot meet the needs of the future grid. Therefore, it is significant to solve the energy supply problem of numerous sensors to promote the construction of new power grid and improve the utilization rate of renewable energy. As an emerging energy harvesting device, triboelectric nanogenerators (TENG) are suitable for developing self-powered sensors and powering low-power sensors due to their mall size, high efficiency, low cost, and environmental friendliness. At the same time, due to the abundant, stable, and widely distributed magnetic field around the equipment in the grid, it can provide continuous excitation for the TENG. Therefore, applying magnetic field energy-harvesting TENG in the future power grid has a broad development prospect. This paper analyzes the development trend and the crucial problems facing the power grid in the future. We review the research and application of TENG based on the magnetic field in recent years and explain the mechanism of TENG in detail. Finally, the application prospect of TENG in the future power grid has been prospected. This paper can provide a reference for applying magnetic field energy harvesting triboelectric nanogenerators in future power grids.

为了满足电网运行控制的要求,在电网中构建广泛的传感器网络是未来的发展趋势。然而,由于成本高、长期持续供电困难、能耗大、废弃电池带来的环境问题,传统的以电池为传感器的供电模式与中国碳峰值和碳中和的目标不一致。它不能满足未来电网的需求。因此,解决众多传感器的能源供应问题,对推动新电网建设,提高可再生能源利用率具有重要意义。摩擦电纳米发电机(TENG)作为一种新兴的能量收集装置,具有体积小、效率高、成本低、环境友好等优点,适用于开发自供电传感器和为低功耗传感器供电。同时,由于电网中设备周围丰富、稳定、分布广泛的磁场,可以为TENG提供持续的激励。因此,在未来电网中应用磁场集能TENG具有广阔的发展前景。本文分析了未来电网的发展趋势和面临的关键问题。本文综述了近年来基于磁场的TENG的研究和应用,并对TENG的机理进行了详细的阐述。最后,对TENG在未来电网中的应用前景进行了展望。本文为磁场能量收集摩擦纳米发电机在未来电网中的应用提供了参考。

Furthermore, efforts to develop high-efficiency ionovoltaic device powered by small water droplets indicate a potential contribution to the advancement of green energy systems that complement solar and wind power generation and address environmental pollution and energy shortages. This review paper explores the evolution of energy harvesting technologies using water motion, with a particular focus on ionovoltaics as an emerging field. By establishing the fundamentals, this study investigates solid–liquid interfaces, semiconductor properties, and natural water motion-driven ionovoltaic phenomena and also highlights that extensive research on complex ion/interface phenomena can have practical applications in diverse industrial fields.

Unlocking the potential of metal halide perovskite thermoelectrics through electrical doping: A critical review 通过电掺杂释放金属卤化物钙钛矿热电材料的潜力:综述

Over the past decade, metal halide perovskites (MHPs) have received great attention, triggered by the tremendous success of their record-breaking power conversion efficiency values in solar cells. Recently, there have been significant interests in fully utilizing their unique properties by exploring other device applications including thermoelectrics, which is promising due to their ultralow thermal conductivity and high mobility relative to their competitors among solution-processable materials. However, the performance of MHP thermoelectrics reported so far falls significantly short of theoretical predictions, as the doping levels achieved to date are typically below the optimum values for maximizing the thermoelectric power factor, indicating the need for effective electrical doping strategies. In this critical review, recent studies aimed at enhancing the thermoelectric properties of MHPs are discussed, with a focus on the relatively under-explored area of electrical doping in MHPs. The underlying charge transport mechanism and doping effect on transport are also examined. Finally, the challenges facing MHP thermoelectrics are highlighted, and potential research visions for achieving highly efficient thermoelectric conversion based on MHPs are offered.

在过去的十年中,金属卤化物钙钛矿(MHPs)受到了极大的关注,这是由于其在太阳能电池中破纪录的能量转换效率值取得了巨大成功。最近,通过探索包括热电材料在内的其他器件应用,人们对充分利用其独特性能产生了极大的兴趣,热电材料由于其超低导热性和相对于溶液可加工材料的竞争对手的高迁移率而前景广阔。然而,迄今为止报道的MHP热电材料的性能明显低于理论预测,因为迄今为止实现的掺杂水平通常低于最大化热电功率因数的最佳值,这表明需要有效的电掺杂策略。在这篇重要的综述中,讨论了最近旨在提高MHPs热电性能的研究,重点关注了MHPs中电掺杂的相对未被开发的领域。本文还研究了潜在的电荷输运机制和掺杂对输运的影响。最后,强调了MHP热电材料面临的挑战,并提出了基于MHP热电材料实现高效热电转换的潜在研究前景。

In this critical review, recent studies aimed at enhancing the thermoelectric properties of MHPs are discussed, with a focus on the relatively under-explored area of electrical doping in MHPs. The underlying charge transport mechanism and doping effect on transport are also examined. Finally, the challenges facing MHP thermoelectrics are highlighted, and potential research visions for achieving highly efficient thermoelectric conversion based on MHPs are offered.</p><p>\u0000 <figure>\u0000 <div><picture>\u0000 <source></source></picture><p></p>\u0000 </div>\u0000 </figure></p>","PeriodicalId":93174,"journal":{"name":"EcoMat","volume":"5 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eom2.12406","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46104115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All-inorganic perovskite solar cells have shown great potential owing to their superior stability against thermal stress and moisture compared to organic–inorganic perovskite solar cells. However, there are some remaining issues in the all-inorganic perovskite solar cell fabrication process, such as the low solubility of the perovskite precursors and the occurrence of the secondary phases. In this review, we focus on all-inorganic CsPbBr3 perovskite solar cells and categorize them based on their fabrication process. Various processes and strategies that have been developed to solve the aforementioned issues including the general process of multistep spin coating are thoroughly investigated. Finally, a summary of the various processes for the all-inorganic CsPbBr3 perovskite solar cells and an outlook for the development of highly efficient all-inorganic perovskite solar cells are proposed.

Vanadium‐based compounds with various crystal structures are highly promising cathode materials for aqueous zinc‐based batteries. However, their further development is limited due to the low electrical conductivity, slow zinc ion diffusion, and weak structural stability. It is a feasible strategy to resolve above mentioned issues through surface modification. Herein, we design bi‐phase coexisting CaV2O6/NaV6O15 nanobelt structures with abundant interfaces, which provide more reactive sites than single‐phase ones. The samples as the electrode materials deliver a specific capacity of 312 mAh g−1 at 5 A g−1 after 2000 cycles. They still keep a capacity of 231 mAh g−1 at 10 A g−1 with a cycle life of 6500 times.image
具有多种晶体结构的钒基化合物是极有前途的锌基水性电池正极材料。然而,由于其电导率低、锌离子扩散缓慢、结构稳定性弱,限制了其进一步发展。通过表面改性是解决上述问题的可行策略。在此,我们设计了具有丰富界面的双相共存的CaV2O6/NaV6O15纳米带结构,该结构比单相结构提供了更多的反应位点。作为电极材料的样品在5ag−1下经过2000次循环后的比容量为312 mAh g−1。它们在10a g−1时仍然保持231 mAh g−1的容量,循环寿命为6500次

The commercial plywood is mainly made of high‐value wood veneer and formaldehyde‐based adhesives, which pose a major risk to human health and environmental protection. Here, we report an all‐natural plywood made of self‐adhesive bark veneer directly from hardy rubber trees (HRT) via delignification, epoxidation reaction and densification. The resulting bark veneer is demonstrated with sandwich structures featuring natural integration between cellulose and biopolymer Eucommia ulmoides gum (EUG). The intrinsic EUG act as a potential strong “self‐adhesive” and water‐proofing agent, leading to bark veneer with high hardness, excellent hydrophobicity, wear resistance, and low thermal conductivity. Furthermore, we can produce the self‐adhesive plywood on a large scale directly from HRT bark using this approach without any adhesives, endowing it with environmental friendliness, safety in use, and health benefits of human beings. Combining its efficient and low‐cost production, the bark veneer shows great promise in fabricating high‐performance and environmentally sustainable plywood.image
商用胶合板主要由高价值木单板和甲醛基粘合剂制成,对人类健康和环境保护构成重大风险。在这里,我们报道了一种由耐寒橡胶树(HRT)通过脱木素、环氧化反应和致密化直接制成的自粘树皮单板制成的全天然胶合板。所得到的树皮单板具有三明治结构,其特征在于纤维素和生物聚合物杜仲胶(EUG)之间的自然整合。固有的EUG作为一种潜在的强“自粘”和防水剂,使树皮单板具有高硬度、优异的疏水性、耐磨性和低导热性。此外,我们可以在不使用任何粘合剂的情况下,使用这种方法直接从HRT树皮大规模生产自粘胶合板,使其具有环境友好性、使用安全性和对人类健康的益处。树皮单板结合其高效和低成本的生产,在制造高性能和环境可持续的胶合板方面显示出巨大的前景。图片

Although perovskite solar cells have achieved efficiency over 25%, the toxic of Pb content remains severe problem given its commercial prospect. Especially when the devices suffer harsh weather, the Pb content can easily leak out to soil and water. Chelating resins (CRs) exhibit excellent superiority in treating waste water in industrial field, since the functional groups in CRs can adsorb divalent metal ion to soften and purify waste water. Herein, an iminodiacetic acid (IDA)-CR is introduced as encapsulation over perovskite solar cells for the first time. The IDA-CR exhibits high surface area and excellent adsorption capability. Qualitative and quantitative analysis of Pb leakage are studied, and the devices with encapsulation of IDA-CR can detain over 90% of Pb compared with control devices without encapsulation after immersed in deionized water for 12 h even in acid situation or after heating. This IDA-CR method provides a new strategy towards environmental and biological-friendly perovskite optoelectronic devices.

尽管钙钛矿太阳能电池的效率已超过25%,但鉴于其商业前景,铅含量的毒性仍然是一个严重的问题。特别是当设备遭受恶劣天气时,铅含量很容易泄漏到土壤和水中。螯合树脂在处理工业废水方面表现出优异的优越性,因为螯合树脂中的官能团可以吸附二价金属离子来软化和净化废水。本文首次引入亚氨基二乙酸(IDA)-CR作为钙钛矿太阳能电池的封装。IDA-CR表现出高表面积和优异的吸附能力。对铅泄漏进行了定性和定量分析,在去离子水中浸泡12小时后,与未封装的对照装置相比,封装IDA‐CR的装置可滞留90%以上的铅 h即使在酸性条件下或加热后。这种IDA-CR方法为环境和生物友好的钙钛矿光电器件提供了一种新的策略
