The light weight, good bending resistance and low production cost make flexible perovskite solar cells (PSCs) good candidates in wearable electronics, portable charger, remote power, and flying objects. High power conversion efficiency (PCE) plays a cruci
All-inorganic cesium lead bromide (CsPbBr3) perovskite is attracting growing interest as functional ma-terials in photovoltaics and other optoelectronic devices due to its superb stability. However, the fabri-cation of high-quality CsPbBr3 films still rem
Recently, MnO2 has gained attention as an electrode material because of its very high theoretical capacity and abundant availability. However, the very high volumetric change caused by its conversion-type reac-tion results in bad reversibility of charge-d
Herein, the relationship between the structure and base properties of Mg–Al hydrotalcite catalysts was comprehensively investigated in relation to heat treatment and rehydration processes, which are well known as memory effects of hydrotalcite. The struct
Lithium–sulfur (Li–S) battery as a high-energy density electrochemical energy storage system has at-tracted many researchers\' attention. However, the shuttle effect of Li–S batteries and the challenges associated with lithium metal anode caused poor cy
Lithium sulfur (Li-S) batteries are the promising power sources, but their commercialization is signifi-cantly impeded by poor energy-storage functions at high sulfur loading. Here we report that such an issue can be effectively addressed by using a musse
从氯丁橡胶的防护体系、增塑剂和补强填充剂等方面对其耐热老化性能进行了研究.结果表明,防护体系采用防老剂ZA/NBC和微晶蜡并用,增塑剂使用TOTM/TP95,补强填充体系选择无机填料和炭黑并用可有效提升氯丁橡胶的耐热老化性能.
Poly (ethylene-oxide) (PEO)-based membranes have attracted much attention recently for CO2 separation because CO2 is highly soluble into PEO and shows high selectivity over other gases such as CH4 and N2. Unfortunately, those membranes are not strong enou
Transition metal oxide (TMO) nanoarrays are promising architecture designs for self-supporting oxygen electrodes to achieve high catalytic activities in lithium-oxygen (Li- O2) batteries. However, the poor con-ductive nature of TMOs and the confined growt
研究了NBR的耐臭氧性能、物理性能、热老化性能以及耐1RM903油性能的变化.结果表明,在NBR配方中添加微晶蜡和防老剂4020可提高胶料的耐臭氧性能,且随着用量的增加,耐臭氧性能逐渐增大.当微晶蜡与4020用量分别为3份与2份时,硫化胶试样满足在拉伸20%、温度40℃、臭氧浓度为50×10-8、时间为72h下无龟裂要求.与不添加微晶蜡与4020的原配方相比,两者在硫化特性、物理性能、热老化性能和耐IRM903油性能方面无明显差别.
