Dynamics of solvent-free grafted nanoparticles [PDF]
The Journal of Chemical Physics, 2012 The diffusivity and structural relaxation characteristics of oligomer-grafted nanoparticles have been investigated with simulations of a previously proposed coarse-grained model at atmospheric pressure. Solvent-free, polymer-grafted nanoparticles as well as grafted nanoparticles in a melt were compared to a reference system of bare (ungrafted ...

Enzymatic Kinetics of Solvent-free Esterification with Bio-imprinted Lipase [PDF]
Chemical and Biochemical Engineering Quarterly, 2020 To avoid the use of compounds that burden the environment, a solvent-free enzymatic reaction was the focus of this study. Investigated were the catalytic activities and kinetics of lipases that were pretreated with carboxylic acids for the solvent-free ...

Mechanochemical Solvent‐Free Catalytic C−H Methylation [PDF]
Angewandte Chemie International Edition, 2020 AbstractThe mechanochemical, solvent‐free, highly regioselective, rhodium‐catalyzed C−H methylation of (hetero)arenes is reported. The reaction shows excellent functional‐group compatibility and is demonstrated to work for the late‐stage C−H methylation of biologically active compounds.
