Silica was then characterized by Fourier Transform Infrared (FT-IR) to indicate the silanol (Si-OH) groups at a wavenumber of 3367.70cm1. The infrared spectroscopy data also showed the results in absorption at wavenumber 1056.99cm1 and 784.38cm1. This data indicated asymmetric and symmetric ...
wool fiberanti-felting finishsol-gel techniqueA sol type anti-felting agent containing PPD-[Si(OH)_3]_2 synthesized and applied to the wool with pad-dry-cure process. The structure of the prepolymer was characterized by FT-IR spectroscopy and the film transparency and the fiber microstru...
FT-IR spectraThin and homogeneous SiO 2 films were prepared on aluminium plates from Si(OC 2 H 5 ) 4 -C 2 H 5 OH-H 2 O solutions which had controlled compositions and did not contain any acid as a catalyst. Aluminium with the coatings showed good corrosion resistance. However, SiO 2...
Two [V15M6(OH)6O42(Cl)]7鈭 (M = Si for 1, Ge for 2) cluster anions with protonated amines as counterions have been synthesized under hydrothermal conditions and characterized by FT-IR, energy dispersive spectroscopy, XPS, powder X-ray diffraction, thermogravimetric analysis (TGA), ...
1 HNMR as well as IR data suggest the presence of a mixture of both conformers in C 6 D 6 . Hydrogen-bonded adducts of Mes 2 Si(OH)(μ-O)Si(OH)Mes 2 with ethers such as diethylether, dimethoxyethane or dioxane were observed in the solid state, where they form polymeric chain-...
