Liquid-Phase Exfoliation of Biochars in Green Solvents and Correlation with Solvent Parameters [PDF]
, 2021 Liquid-phase exfoliation (LPE) is a process frequently used to overcome the interactions between layers in layered materials to produce small sheets of material, with remarkable properties and high value applications. Materials are prepared via direct or indirect sonication in a solvent that must be able to effectively disperse and stabilize the sheets

Role of solvent for globular proteins in solution
, 2005 The properties of the solvent affect the behavior of the solution. We propose a model that accounts for the contribution of the solvent free energy to the free energy of globular proteins in solution.

Integrally skinned polysulfone hollow fiber membranes for pervaporation [PDF]
, 1994 From polysulfone as polymer, integrally skinned hollow fiber membranes with a defect-free top layer have been spun. The spinning process described here differs from the traditional dry-wet spinning process where the fiber enters the coagulation bath ...

Chain length dependence of the polymer-solvent critical point parameters
, 1996 We report grand canonical Monte Carlo simulations of the critical point properties of homopolymers within the Bond Fluctuation model. By employing Configurational Bias Monte Carlo methods, chain lengths of up to N=60 monomers could be studied.
