Discussions on the Properties of Emulsion Prepared by Using an Amphoteric Chitosan as an Emulsifier

open access: yesApplied Sciences, 2022
A typical emulsion contains oil and water phases, and these two phases can be combined by an emulsifier with both lipophilic and hydrophilic groups to form a mixture. If the component of water is more than oil, the mixture is termed as o/w emulsion.

Catalytic enantioselective reductive domino alkyl arylation of acrylates via nickel/photoredox catalysis

open access: yesNature Communications, 2021
Enantioenriched α-aryl propionic acids are an important class of nonsteroidal anti-inflammatory medications. Here the authors use a visible-light-promoted photoredox/nickel catalyzed method to form such compunds via a three-component alkyl arylation of ...
