The distribution of electrostatic potential in the vicinity of the hydroxylated and trimethylsilylated surface of silica was calculated in the semiempirical PM3 approximation. A new mechanism is proposed for the bonding of electron-donating molecules with the surface of hydrophobized silicas. 相似文献

The problem on the evolution of electron spin in inhomogeneous magnetic fields of special type is solved on the basis of the
classical Bargmann-Michel-Telegdi equation. The results obtained are used to analyze the behavior of electron spin in magnetic
undulators.

The cyclocondensation of α-acylacetamidines with esters of 2-fluoro-5-nitrobenzoic and 4-chloro-2-methyl-5-pyrimidinecarboxylic
acids leads to condensed azines. The reaction proceeds chemoselectively such that the α-carbon atom of the amidine replaces
the halogen atom in the aromatic ring, while the amino group reacts with the ester group.

We studied how treatment of 0.64 wt % Pt/SiO2 catalyst with a glow-discharge plasma in O2 and a high-frequency plasma in H2 (HF H2) influences the cyclohexane dehydrogenation reaction. The effect of plasmochemical treatment on the average diameter of platinum
particles was established by the method of X-ray diffraction analysis. It was found that oxygen plasma increases the surface
area of the metal by ∼15% and diminishes activity by raising the activation energy and reducing the number of active centers
per unit surface of the metal. The HF H2 plasma increases the reaction rate constant many times over, due to the number of active centers per unit surface of the
metal rising sharply while the size of the Pt particles remains unchanged. 相似文献

layers are investigated by means of secondary ion mass spectrometry (SIMS). Experimental results obtained with the use of
a TOF-SIMS 5 instrument are presented. To surmount the so-called matrix effect, SIMS analysis is performed by using complex
secondary ions: Ge2−, CsGe+, and Cs2Ge+. 相似文献
