One more general method for solving Oseen's equations
(Springer Wien, Wien, 1991)
In this paper we have proposed a new method for solving the Oseen's equations. It has been testified in the case of the normal flow around the cylinder for the Re number being much smaller than 1. The step forward was to ...
The electro-oxidation of glycerol on the gold(100)-oriented single-crystal surface and poly crystalline surface in 0.1 M NaOH
(Elsevier Science Sa, Lausanne, 1991)
On the thermolysis of poly(chloroalkyl methacrylates) and poly(chloroalkyl acrylates): Part 1-Poly(2,2,2-trichloroethyl methacrylate)
(Elsevier Sci Ltd, Oxford, 1991)
The thermal degradation of poly(2,2,2-trichloroethyl methacrylate). PTCMA, in the absence and presence of O2 was studied and compared with that of poly(ethyl methacrylate), PEMA. In the absence of O2 the two polymers behaved ...
The thermal stability of some poly(di-aryl itaconates)
(Springer, New York, 1991)
The non-oxidative thermal stability of poly(di-aryl itaconates) was established by thermogravimetric analysis. The polymers investigated were poly(diphenyl itaconate) (PDPhI), poly(di-ortho-, meta- and para-tolyl itaconates) ...
Preparation of aluminophosphate molecular sieves in the presence of nickel( II) and copper( II)
(Butterworth-Heinemann, 1991)
Nickel(ll)-substituted aluminophosphates of structure types 21 and 12 (NiAPO-21 and NiAPO-12) have been prepared hydrothermally in the presence of ethylenediamine as the template. U.v.-visible spectroscopy of NiAPO-21 ...
The structure of CoSAPO-34, containing i-propylamine as a template
(Butterworth-Heinemann, 1991)
The crystal structure of a cobalt silicoaluminophosphate, CoSAPO-34, is reported. The crystals belong to the rhombohedral R3 space group with unit cell parameters a = 13.797(7) and c = 14.898(7) A. The final R index was ...

Preparation and Properties of Sodalite-Type Aluminophosphates Containing Silicon, Cobalt and Zinc
(CSIRO PUBLISHING, 1991)
The SAPO, MeAPO and MeSAPO microporous materials (Me=Co2+ and/or 2n2+) having a sodalite structure have been obtained hydrothermally at 200°C in the presence of tetramethylammonium ion as the template. The SAPO and MeSAPO ...
Oxygen reduction on iron-IV. The reduction of hydrogen peroxide as the intermediate in oxygen reduction reaction in alkaline solutions
(Pergamon-Elsevier Science Ltd, Oxford, 1991)
The kinetics of hydrogen peroxide reduction were studied on iron in borate buffered and unbuffered solutions of pH ranging from 8.6 to 13.8, with and without the presence of chloride ions. A rotating disk electrode was ...
Oxygen reduction on iron-V. Processes in boric acid-borate buffer solutions in the 7.4-9.8 pH range
(Pergamon-Elsevier Science Ltd, Oxford, 1991)
O2 and H2O2 reduction was studied on Puratronic iron (99.995%) in borate buffer solutions of various pH ranging from 7.4 to 9.8. In solutions of pH < 9.3 the E-j curves are of quite irregular shapes and the limiting ...
