Structural Mechanism of an Efficacy Photoswitch Targeting the β2‐adrenergic Receptor
Angewandte Chemie International Edition, EarlyView.Time‐resolved structures from x‐ray free‐electron laser measurements combined with cellular assays demonstrate how the photoswitchable β‐blocker photoazolol‐1 acts as an efficacy switch of β2‐adrenergic receptor function. Light‐induced ligand repositioning shifts activity from inverse agonism toward neutral antagonism by altering local helical ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Heavy metals in municipal waste incineration fly ash are potentially harmful to the ecological environment and human health. To mitigate the hazards of fly ash, this study attempts to detoxify fly ash through organic acid washing pretreatment coupled with cement/sodium diethyldithiocarbamate (DDTC) solidification.

Hydration mechanism of using steel slag as binder for backfill materials in potash mines
工程科学学报, 2018 The depth and scale of potash mines is currently increasing. Backfill materials with higher homogeneity and greater fluidity property are required to prevent blocking and ensure that filling materials are transported safely to the underground mines.

Chemistry – A European Journal, EarlyView.Staggered, square, and heavily bent dimers occur in the five known solvatomorphs of paddlewheel (PW) complex [PtVO(SOCPh)4]. These and other structural motifs are well within energetic reach due to the shallow potential energy surface that guides dimerization and are included in a revised classification of available structural data on heterobimetallic ...
