Solvent-free autocatalytic supramolecular polymerization [PDF]
Abstract Solvent-free chemical manufacturing is one of the awaited technologies for addressing an emergent issue of serious environmental pollution. Here, we report "solvent-free autocatalytic supramolecular polymerization (SF-ASP)", where a phthalonitrile derivative with hydrogen-bonding side chains as the monomer is autocatalytically ...

Solvent Control of Electron Transfer Dynamics [PDF]
We investigate the charge-transfer-to-solvent (CTTS) dynamics of sodide in several solvents. Since this CTTS system has only electronic degrees of freedom, the dynamics provide a window into how solvent motions control electron ...

Phase Behavior that Enables Solvent-Free Carbonate-Promoted Furoate Carboxylation [PDF]
A solvent-free transformation that enables production of polyester precursors from inedible biomass proceeds from a heterogeneous reaction mixture containing both solid and molten components.

Dynamics of solvent-free grafted nanoparticles [PDF]
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 ...
