Industrial solvents and psychological effects
Clinics in Occupational and Environmental Medicine, 2004Organic solvents are widely used in industries for cleaning, degreasing, and other processes. The high dose neurotoxicity of occupational solvents is evident, and the existence of residual effects following lower dose exposure remains a focus of interest 30 years after initial reports of behavioral changes in painters from the Scandinavian literature ...

Solvent effects on dinucleotide conformation
Journal of Molecular Biology, 1972Abstract The effect of the addition of organic solvents and reagents on the absorption, optical rotatory dispersion and circular dichroism of ApA was investigated. The added reagents were dioxane, ethylene glycol, glycerol, dimethylsulfoxide, trimethylphosphate, guanidine hydrochloride, formamide and tetrahydrofuran.

The effect of solvent on the α-effect: the MeCN–H2O solvent system
Chemical Communications, 2000The increasing α-effect observed in MeCN–H2O solvent mixtures, which contrasts with the previously found bell-shaped dependence on solvent composition in the DMSO–H2O system, is attributed to the differential solvent effect on basicities of the α- and normal nucleophiles in the former case.

Solvent effects on the stability of A7U7p
Biochemistry, 1985The thermodynamics of double-helix formation were measured spectrophotometrically for A7U7 in water at 1 M NaCl and for A7U7p in a variety of solvent mixtures and salt. Comparison of the A7U7 results with calorimetric measurements indicates duplex formation involves intermediate states.

Effects of Solvents on Acetylcholine Conformation
Nature, 1966IN earlier communications1–3 we reported the results of our investigations with acetylcholine and related substances. These led us to conclude that the acetyl group is activated primarily by an inductive influence of the quaternary nitrogen. This conclusion was based in large measure on the carbonyl stretching frequencies which were observed for ...

Solvents and Solvent Effects in Biomass Conversion
2014Hydrogenation and hydrogenolysis of molecules derived from plant biomass are reactions often performed in liquid phase because the highly functionalized biomass molecules (e.g. cellulose, hemicellulose, sugars, and lignin) cannot be vaporized without undergoing thermal decomposition.

Solvent effects in vibrational spectroscopy
Transactions of the Faraday Society, 1960The effects of solute-solvent interactions on the frequencies, intensities and shapes of the infra-red absorption bands of dissolved molecules are discussed. The interaction potential energy U between a single solute molecule and its environment is treated as a variable depending upon the solvent configuration and on the normal co-ordinates of the ...
