Planarization of a surface of nanoporous silica–titania composition by atomic-molecular chemical assembly

The processes involved in the planarization of the surface of nanoporous SiO₂ by the atomicmolecular deposition of nanoscale TiO₂ films were studied in regimes with different degrees of penetration of TiO₂ into SiO₂ nanopores. The technological process parameters that correspond to different regimes of surface planarization were examined. The degree of penetration of TiO₂ into SiO₂ nanopores was monitored using reflection ellipsometry by measuring the depth distribution of the refraction index within the two-layer model.     

Tertiary aminotrichloroethylphosphines and their oxides

Conclusions Secondary phosphines react with the N-carbomethoxy- and N-benzoyltrichloroacetimines to give tertiary aminotrichloroethylphosphines.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimichaskaya, No. 6, pp. 1423–1424, June, 1984.     

Reactions of phenyl- and trimethylsilylphenylphosphines with thiobenzophenone

Conclusions The reaction of phenyl- and trimethylsilylphenylphosphines with thiobenzophenone with a 11 reagent ratio proceeds with the formation of secondary phosphines.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 9, pp. 2116–2117, September, 1984.
