Glass structure and ion dynamics of lead-cadmium fluorgermanate glasses
(American Institute of Physics (AIP), 2004-05-22)
Glass structure and fluorine motion dynamics are investigated in lead-cadmium fluorgermanate glasses by means of differential scanning calorimetry, Raman scattering, x-ray absorption (EXAFS), electrical conductivity (EC), ...
Gelation of siloxane-poly(oxypropylene) composites
(Elsevier B.V., 2002-06-01)
The viscoelastic properties of siloxane-poly(oxypropylene) (PPO) nanocomposites prepared by the sol-gel process has been analyzed during gelation by dynamic rheological measurements. The changes of storage and loss moduli, ...
Analysis of the ethidium bromide bound to DNA by photoacoustic and FTIR spectroscopy
(Amer Soc Photobiology, 2001-10-01)
Under physiological conditions B-form DNA is an exceedingly stable structure. However, experimental evidences obtained through nuclear magnetic resonance and fluorescence anisotropy suggest that the structure of the double ...
Chemical and spectroscopic studies of a new palladium(II) complex with N-acetyl-L-cysteine
(Taylor & Francis Ltd, 2008-01-01)
Chemical and spectroscopic studies of a new palladium(II) N-acetyl-L-cysteine complex are described. Elemental analyses for the solid complex are consistent with the formula [Pd(C(5)H(8)NO(3)S)(2)] H(2)O or [Pd(NAC)(2)] ...
Effects of Synthesis Conditions on the Nanostructure of Hybrid Sols Produced by the Hydrolytic Condensation of (3-Methacryloxypropyl)trimethoxysilane
(Amer Chemical Soc, 2009-08-20)
Polysilsesquioxanes containing methacrylate pendant groups were prepared by the sol-gel process through hydrolysis and condensation of (3-methacryloxypropyl)trimethoxysilane (MPTS) dissolved in a methanol/methyl methacrylate ...
