Computer simulation of bottle brush polymers with flexible backbone: Good solvent versus Theta solvent conditions [PDF]
J. Chem. Phys. 135, 164903 (2011), 2011 By Molecular Dynamics simulation of a coarse-grained bead-spring type model for a cylindrical molecular brush with a backbone chain of $N_b$ effective monomers to which with grafting density $\sigma$ side chains with $N$ effective monomers are tethered, several characteristic length scales are studied for variable solvent quality.

Conformational isomerization dynamics in solvent violates both the Stokes-Einstein relation and Kramers' theory [PDF]
arXiv, 2023 Molecular isomerization kinetics in liquid solvents are determined by a complex interplay between the friction acting on a rotating dihedral due to interactions with the solvent, internal dissipation effects (also known as internal friction), the viscosity of the solvent, and the free energy profile over which a dihedral rotates.

How hydrophobic drying forces impact the kinetics of molecular recognition [PDF]
Proc. Natl. Acad. Sci. USA 110, 13277 (2013), 2013 A model of protein-ligand binding kinetics in which slow solvent dynamics results from hydrophobic drying transitions is investigated. Molecular dynamics simulations show that solvent in the receptor pocket can fluctuate between wet and dry states with lifetimes in each state that are long enough for the extraction of a separable potential of mean ...

Review of microscale dynamics of dilution-induced asphaltene precipitation under controlled mixing conditions [PDF]
arXiv, 2022 As the most complex and heaviest component in bitumen, asphaltene precipitation induced by solvent dilution is important in oil sands extraction to remove solids and water from bitumen froth through dilution by paraffinic solvents. This review will compare asphaltene precipitation to dilution-induced solvent shifting in aqueous systems via the ouzo ...
