The acicular α-Al2O3 (width<4 μm, length<20 μm) obtained by the thermal decomposition of synthetic diaspore at 530, 600 and 1300°C was characterized by means of XRD, SEM, FTIR, 27Al MAS-NMR, XPS, nitrogen adsorption-desorption isotherm and BET surface area. The high adsorptive act...
Complementary transmission FTIR experiments monitored the Si-Cl, Si-H and Si-O-Si vibrations of the surface species during the reaction of H2O on chlorinated porous silicon surfaces. At temperatures T less than or equal to 700 K, the oxygen uptake resulting from H2O adsorption was small, a...
The parameters of the nanocomposite structures are studied by FTIR spectroscopy and impedance spectroscopy. It is shown that, in such structures, the mechanisms of charge-carrier transport are defined by the properties of Si nanocrystallites and the corresponding oxide as well as by interaction ...
