A 3D printer that rapidly produces large batches of custom biological tissues could help make drug development faster and less costly. Nanoengineers at the University of California San Diego developed...
阅读全文Metal halide perovskites have been under intense investigation over the last decade due to the remarkable rise in their performance in optoelectronic devices such as solar cells or light-emitting diod...
阅读全文The presence of amino acids on the prebiotic Earth is widely accepted, either coming from endogenous chemical processes or being delivered by extraterrestrial material. On the other hand, plausibly pr...
阅读全文Researchers at the University of Illinois Chicago have developed a novel continuous-flow microfluidic device that may help scientists and pharmaceutical companies more effectively study drug compounds...
阅读全文Glass is one of the most common materials we use every day, but the detailed structure of this non-metallic and non-liquid material has always been a major mystery in science. A research team co-led b...
阅读全文Propylene oxide (PO) is one of the important propylene derivatives with high reactivity, which is used extensively as a raw material for the manufacture of numerous commercial chemicals. The titanosil...
阅读全文Fischer-Tropsch synthesis (FTS) has been applied as the core technology of coal-to-liquid and gas-to-liquid processes in industry. However, the product selectivity control of syngas conversion still r...
阅读全文The geometric isolation of metal species in single-atom catalysis (SACs) not only maximizes the atomic utilization efficiency, but also endows SACs with unique selectivity in various transformations.
阅读全文A simple chemical process developed at Rice University creates light and highly absorbent aerogels that can take a beating.
阅读全文成果简介 弱碳-金属键结合碳-碳键的动力学惰性,使得金属催化的碳-碳键活化,具有很高的挑战性。目前,大多数报道的C-C键激活方法,涉及小环的应变释放裂解,以弥补与C-C键裂解相关的不利动力学和热力学损失。 近日,...
阅读全文萜类及其衍生物广泛存在于药物,农药以及香料中。由于其复杂的骨架结构和突出的生物活性,萜类化合物的合成一直是有机合成化学的难点和热点之一。近年来,基于“切断-重组”(“cut-and-sew”)策略的环化反应,即过...
阅读全文由可再生能源驱动的二氧化碳电还原(CO2RR)制备有价值的烯烃和醇,是一种有效的碳中和途径。乙烯是化学工业的前体,其年全球产量为1.4亿吨,市场价值为1820亿美元,因此已被优先列为CO2RR的目标。然而,就效率、生产...
