General description
氢氧化钾(KOH)是吸湿性水溶性碱，通过电解氯化钾溶液合成。它是合成许多钾化合物的原料。KOH可与CO2反应形成碳酸钾。该性质可用于吸收CO2。它作为催化剂参与醛醇缩合反应。硅的KOH各向异性蚀刻可用于使用常规接触光蚀刻制造亚微米氮化硅波导。KOH粉末可用于制备查耳酮。

Stable isotopic profiling has long permitted sensitive investigations of the metabolic consequences of genetic mutations and/or pharmacologic therapies in cellular and mammalian models. Here, we describe detailed methods to perform stable isotopic profiling of intermediary metabolism and metabolic flux in

Among the large family of transition metal dichalcogenides, recently ReS2 has stood out due to its nearly layer-independent optoelectronic and physicochemical properties related to its 1T distorted octahedral structure. This structure leads to strong in-plane anisotropy, and the presence of
