The green solvent: a critical perspective

Clean Technologies and Environmental Policy, 2021
Solvents are important in most industrial and domestic applications. The impact of solvent losses and emissions drives efforts to minimise them or to avoid them completely. Since the 1990s, this has become a major focus of green chemistry, giving rise to

Total Lagrangian Finite Element Formulation of the Flory-Rehner Free Energy Function

Revista Facultad de Ingeniería Universidad de Antioquia, 2014
The total Lagrangian finite element implementation of the Flory-Rehner free-energy function in the framework of a hyperelastic material model is addressed. It is explicitly given all the equations required to implement this material model in an implicit

Coupling nonpolar and polar solvation free energies in implicit solvent models [PDF]

, 2006
Recent studies on the solvation of atomistic and nanoscale solutes indicate that a strong coupling exists between the hydrophobic, dispersion, and electrostatic contributions to the solvation free energy, a facet not considered in current implicit ...

PLATON SQUEEZE: a tool for the calculation of the disordered solvent contribution to the calculated structure factors.

Acta Crystallographica Section C Structural Chemistry, 2015
The completion of a crystal structure determination is often hampered by the presence of embedded solvent molecules or ions that are seriously disordered. Their contribution to the calculated structure factors in the least-squares refinement of a crystal

Compilation of Henry's law constants (version 5.0.0) for water as solvent

Atmospheric Chemistry and Physics, 2015
. Many atmospheric chemicals occur in the gas phase as well as in liquid cloud droplets and aerosol particles. Therefore, it is necessary to understand their distribution between the phases.

Coupling hydrophobic, dispersion, and electrostatic contributions in continuum solvent models [PDF]

, 2005
Recent studies of the hydration of micro- and nanoscale solutes have demonstrated a strong {\it coupling} between hydrophobic, dispersion and electrostatic contributions, a fact not accounted for in current implicit solvent models.
