Polymeric compositions and their method of manufacture [PDF]
, 1972 Filled polymer compositions are made by dissolving the polymer binder in a suitable sublimable solvent, mixing the filler material with the polymer and its solvent, freezing the resultant mixture, and subliming the frozen solvent from the mixture from ...

Dynamics of Proton Transfer in Mesoscopic Clusters
, 1996 Proton transfer rates and mechanisms are studied in mesoscopic, liquid-state, molecular clusters. The proton transfer occurs in a proton-ion complex solvated by polar molecules comprising the cluster environment.

Occupational exposures to solvents and metals are associated with fixed airflow obstruction
Scandinavian Journal of Work, Environment & Health, 2017 OBJECTIVES: This study investigated the associations between occupational exposures to solvents and metals and fixed airflow obstruction (AO) using post-bronchodilator spirometry. METHODS: We included 1335 participants from the 2002–2008 follow-up of the

Are hydrodynamic interactions important in the kinetics of hydrophobic collapse?
, 2012 We study the kinetics of assembly of two plates of varying hydrophobicity, including cases where drying occurs and water strongly solvates the plate surfaces.

"Dry-column" chromatography of plant pigments [PDF]
, 1973 Separation of plant pigments which can be accomplished on thin-layer silica plates with mixture of petroleum ether, halocarbon, acetone, and polar solvent can be readily translated into dry-column technique that yields reproducible chromatograms after ...

Chains in critical fluids and nanopores
, 2004 The conformational behavior of a polymer in a critical binary solvent confined in a porous medium is studied. The size of the polymer in bulk, which is mainly governed by the correlation length of the solvent density fluctuations, depends on the ...

Estudo ab-initio da a-alanina em meio aquoso
Química Nova, 1999 Ab initio Hartree-Fock (HF), Density Functional (B3LYP) and electron correlation (MP2) methods have been used to caracterize the aqueous medium intramolecular hydrogen bond in a-alanine. The 6-31G* and 6-31++G** were taken from Gaussian94 library.
