Flat bulk-solvent model: obtaining optimal parameters [PDF]
Acta Crystallographica Section D Biological Crystallography, 2002 A bulk-solvent correction is regularly used for macromolecular refinement. The flat model of the bulk solvent is considered to be the most reliable. It is shown that the standard procedure does not always result in the optimal values of the bulk-solvent correction parameters.

Metastable liquid-liquid and solid-liquid phase boundaries in polymer-solvent-nonsolvent systems [PDF]
, 1997 In general liquid-liquid demixing processes are responsible for the porous morphology of membranes obtained by immersion precipitation. For rapidly crystallizing polymers, solid-liquid demixing processes also generate porous morphologies.

Parameters Affecting Solvent Production by Clostridium pasteurianum [PDF]
Applied and Environmental Microbiology, 1992 The effect of pH, growth rate, phosphate and iron limitation, carbon monoxide, and carbon source on product formation by Clostridium pasteurianum was determined. Under phosphate limitation, glucose was fermented almost exclusively to acetate and butyrate independently of the pH and growth rate.

Individual tuning of solvent parameters – from organic solvents to ionic liquids
Journal of Molecular Liquids, 2021 Abstract For more than 20 years, we have investigated electron transfer reactions of various types and under various conditions. According to the Marcus theory, solvent parameters have a significant influence on the observed kinetics. Temperature-dependent measurements, such as those used to obtain activation parameters, are especially strongly ...
