Furthermore, we investigated the prediction performance on the cases where the corresponding biological activities increased or decreased by at least three orders of magnitude because these cases are relevant to the activity cliff phenomenon in medicinal chemistry. Finally, we selected four cases that ...
The production of polymers from ethylene requires the ethylene feed to be sufficiently purified of acetylene contaminant. Accomplishing this task by thermally hydrogenating acetylene requires a high temperature, an external feed of H2 gas and noble-metal
It should be noted that China's political scheme has a top-down structure, such that the provincial legislation cannot be independent of the national system. Once the central government adopts a national strategy to support the blue energy economy, full cooperation among provinces will be ...
While studying chemistry at university, Wang said that he often came across an experimental preparation process that he had to explain,but the amount of text was too large and abstract (抽象的). 王先生说,在大学学化学时,他经常遇到需要解释的实验准备过程,但文字量太大且抽象。 That’s why he ...
Alternatively, developing hybrid water electrolysis is crucial for advancing a sustainable energy scheme. In this review, we focus on recent advances in the CF-derived electrodes as highly efficient electrocatalysts for conventional water electrolysis and hybrid water electrolysis. Catalyst design and ...
