Highly stretchable and transparent ionic conducting materials have enabled new concepts of electronic devices denoted as iontronics,with a distinguishable working mechanism and performances from the conventional electronics.However,the existing ionic conducting materials can hardly bear the humidity and temperature change of our daily life,which has greatly hindered the development and real-world application of iontronics.Herein,we design an ion gel possessing unique traits of hydrophobicity,humidity insensitivity,wide working temperature range(exceeding 100℃,and the range covered our daily life temperature),high conductivity(10^(-3)~10^(-5) S/cm),extensive stretchability,and high transparency,which is among the bestperforming ionic conductors ever developed for flexible iontronics.Several ion gel-based iontronics have been demonstrated,including large-deformation sensors,electroluminescent devices,and ionic cables,which can serve for a long time under harsh conditions.The designed material opens new potential for the real-world application progress of iontronics.

Amorphous nanomaterials with long-range disordered structures could possess distinct properties and promising applications,especially in catalysis,as compared with their conventional crystalline counterparts.It is imperative to achieve the controlled preparation of amorphous noble metal-based nanomaterials for the exploration of their phase-dependent applications.Here,we report a facile wet-chemical reduction strategy to synthesize various amorphous multimetallic Pd-based nanomaterials,including PdRu,PdRh,and PdRuRh.The phase-dependent catalytic performances of distinct Pd-based nanomaterials towards diverse catalytic applications have been demonstrated.Specifically,the usage of PdRu nanocatalysts with amorphous and crystalline face-centered cubic(fcc)phases can efficiently switch the ring-opening route of styrene oxide to obtain different products with high selectivity through alcoholysis reaction and hydrogenation reaction,respectively.Moreover,when used as an electrocatalyst for hydrogen evolution reaction(HER),the synthesized amorphous PdRh nanocatalyst exhibits low overpotential and high turnover frequency values,outperforming its crystalline fcc counterpart and most of the reported Pd-based HER electrocatalysts.

In this work,carbonized mussel shell powder(CMSP)was modified by alkyl polyglucosides(APG)and rhamnolipid(RL)to render porous biomass a lipophilic surface,which was innovatively utilized as an environmentally friendly tableware cleaning material.The modified method was two-step hydrotherm-assisted synthesis.A contact angle meter was used to determine the surface hydrophobic property of modified samples(MTAR).The pore and the surface structure of CMSP and MTAR were characterized by BET,SEM,XRD,FTIR and XPS.The effect of removing oil was tested by gravimetric method.The results showed that the surface of MTAR was more porous and fluffier than CMSP,and the specific surface area is increased by 16.76 times.The results showed that when calcining CMSP at 1000℃,the oil removal rate of the synthesized MTAR is the best,and the decontamination rate can reach 87.05%.This research aims to develop a green and environmentally-friendly tableware cleaning material,solve environmental problems,and make full use of waste,which is very conducive to environmental protection.

储罐作为存储油气资源及其产品的主要设备,一旦发生爆炸并产生破坏,罐内燃烧的液体极有可能会从破坏位置流出,进而形成流淌火,将会造成无法挽回的大规模安全事故。以立式拱顶储罐为研究对象,考虑储罐结构与内外流体间的多相耦合,建立了罐内流体-储罐-罐外流体的内爆破坏三维有限元模型,并基于指数内聚力模型失效准则对储罐材料进行描述,通过在材料中插入黏结单元的方法模拟储罐的裂口扩展过程,开展内爆载荷作用下储罐的显式动力学破坏分析。结果表明:储罐起裂位置均位于液位以上,罐体起裂速度与起爆位置呈现正相关;随着内爆载荷的持续作用,储罐裂口不断扩展延伸至液位时,其扩展速度有所减缓;满罐液位状态下储罐未产生裂口,半罐液位降至空罐液位时,储罐平均破坏比由78.8%增至88.4%,储罐破坏程度与液位高度呈现负相关;储罐偏心起爆平均破坏比较中心起爆高1.6%,即储罐偏心起爆破坏程度更严重;储罐容积由1000m^(3)增至5000m^(3)时,若液位占储罐高度低于46%,储罐平均破坏比由88.2%增至88.6%,反之,储罐平均破坏比由86.4%降至84.4%。研究结果可为储罐爆炸事故的预防以及储罐弱顶结构的补强设计提供参考依据。

The development of metallic lithium anode is restrained by lithium dendrite growth during cycling.The solid polymer electrolyte with high mechanical strength and lithium ion conductivity could be applied to inhibit lithium dendrite growth.To prepare the high-performance solid polymer electrolyte,the environment-friendly and cheap bacterial cellulose(BC)is used as filler incorporating with PEO-based electrolyte owing to good mechanical properties and Li salts compatibility.PEO/Li TFSI/BC composite solid polymer electrolytes(CSPE)are prepared easily by aqueous mixing in water.The lithium ion transference number of PEO/Li TFSI/BC CSPE is 0.57,which is higher than PEO/Li TFSI solid polymer electrolyte(SPE)(0.409).The PEO/Li TFSI/BC CSPE exhibits larger tensile strength(4.43 MPa)than PEO/Li TFSI SPE(1.34 MPa).The electrochemical window of composite electrolyte is widened 1.43 V by adding BC.Density functional theory calculations indicate that flex of PEO chains around Li atoms is suppressed,suggesting the enhanced lithium ion conductivity.Frontier molecular orbitals results suggest that an unfavorable intermolecular charge transfer lead to achieve higher potential for BC composite electrolyte.All solid-state Li metal battery with PEO/Li TFSI/BC CSPE delivers longer cycle life for 600 cycles than PEO/Li TFSI SPE battery(50 cycles).Li symmetrical battery using PEO/Li TFSI/BC CSPE could be stable for 1160 h.

复合绝缘子因其性能优越得以在电网领域广泛应用,目前由于鸟类数量增加,鸟啄复合绝缘子的情况日益严重,鸟啄后绝缘子结构遭到破坏,会造成电网线路故障,因此本文研究鸟啄损伤对复合绝缘子性能的影响,为电网运维管理提供参考。首先通过试验对复合绝缘子鸟啄后机电性能进行分析;然后通过人工模拟鸟啄伞裙损伤来研究不同受损占比、不同受损数量对复合绝缘子沿面电场强度与污闪电压的影响;最后开展复合绝缘子护套电蚀损实验、酸浸实验、热老化试验,评估护套损伤对复合绝缘子性能的影响规律。结果表明:鸟啄后复合绝缘子结构遭到破坏,其电气性能、力学性能和防污性能都受到影响,同时护套损伤后,在局部场强、水分、酸、放电产热、机械应力等诸多因素共同作用下,芯棒材料劣化降解,芯棒力学性能下降,存在复合绝缘子异常断裂的风险。
