Effect of glycerol and dimethyl sulfoxide on the phase behavior of lysozyme: Theory and experiments [PDF]
Salt, glycerol and dimethyl sulfoxide (DMSO) are used to modify the properties of protein solutions. We experimentally determined the effect of these additives on the phase behavior of lysozyme solutions. Upon the addition of glycerol and DMSO, the fluid-solid transition and the gas-liquid coexistence curve (binodal) shift to lower temperatures and the

Mixtures of Diethyl Sulfoxide and Methanol: Structure and Thermodynamics [PDF]
Mixtures of sulfoxides with molecular solvents possess interesting physical-chemical properties and may have applications in chemical synthesis. Hereby we confirm and rationalize the previously reported excellent miscibility of diethyl sulfoxide (DESO) with methanol (MeOH).

Effects of dimethyl sulfoxide on surface water near phospholipid bilayers [PDF]
Despite much effort to probe the properties of dimethyl sulfoxide (DMSO) solution, effects of DMSO on water, especially near plasma membrane surfaces still remain elusive. By performing molecular dynamics (MD) simulations at varying DMSO concentrations ($X_{\text{DMSO}}$), we study how DMSO affects structural and dynamical properties of water in the ...

Sulfoxides. V. The Ionization of Sulfoxides in Sulfuric Acid [PDF]
Abstract Contrary to the earlier claim that diphenyl sulfoxide ionizes in nearly 100% sulfuric acid to give a “diphenyl sulfidonium” ion, which can then return to the original sulfoxide when quenched with water, the 18O tracer experiment and a new set of cryoscopic determinations of a few sulfoxides have revealed that the dissociation of

Binary Mixtures of Novel Sulfoxides and Water: Intermolecular Structure, Dynamic Properties, Thermodynamics, and Cluster Analysis [PDF]
Senior dialkyl sulfoxides constitute interest in the context of biomedical sciences due to their abilities to penetrate phospholipid bilayers, dissolve drugs, and serve as cryoprotectants. Intermolecular interactions with water, a paramount component of the living cell, determine performance the sulfoxide-based artificial systems in their prospective ...

Acidity of Strong Acids in Water and Dimethyl Sulfoxide.
Careful analysis and comparison of the available acidity data of HCl, HBr, HI, HClO4, and CF3SO3H in water, dimethyl sulfoxide (DMSO), and gas-phase has been carried out. The data include experimental and computational pKa and gas-phase acidity data from

Fast and Selective Post-polymerization Modification of Conjugated Polymers Using Dimethyldioxirane
Modification of functional groups attached to conjugated polymer backbones can drastically alter the material properties. Oxidation of electron-donating thioalkyl substituents to electron-withdrawing sulfoxides or sulfones is a particularly effective ...

Ice Formation in Model Biological Membranes in the Presence of Cryoprotectors [PDF]
Ice formation in model biological membranes is studied by SAXS and WAXS in the presence of cryoprotectors: dimethyl sulfoxide and glycerol. Three types of phospholipid membranes: DPPC, DMPC, DSPC are chosen for the investigation as well-studied model biological membranes. A special cryostat is used for sample cooling from 14.1C to -55.4C.
