spin-lattice relaxation in cobalt-containing aluminophosphate molecular sieves

Autor: G Mali, V Kaučič

Publikováno v: Solid State Nuclear Magnetic Resonance. 12:243-249

Phosphorus spin-lattice relaxation was studied in aluminophosphate molecular sieves containing various concentrations of either framework or non-framework cobalt. The behaviour of nuclear magnetisation in the presence of these paramagnetic centres wa

The study of autoclaved cellulose fiber-reinforced cement composites

Autor: F. Bakula, V. Kaučič

Publikováno v: Cement and Concrete Research. 25:71-78

The effects of individual or combined addition of sodium water glass (SWG), calcite and CaCl2 into the starting material, consisting of 92 wt.% of Portland cement with sand and 8 wt.% of cellulose fibers, were studied after autoclaving. Bending stren

Structure determination from small crystals of two aluminophosphates CrAPO-14 and SAPO-43

Autor: Marjorie M. Harding, V. Kaučič, Benson M. Kariuki, Graham Cheetham, Pierre J. Rizkallah, Madeleine Helliwell

Publikováno v: Acta Crystallographica Section B Structural Science. 49:413-420

Small single crystals, ca 10 5 μm 3 , of two alumino-phosphates have been used to determine their structures. Both compounds were synthesized with the aim of incorporating chromium into the framework, and for CrAPO-14 the X-ray diffraction results s

Conductive SnO2/Sb powder: preparation and optical properties

Autor: V. Kaučič, Z. Crnjak Orel, M. Hodošček, B. Orel

Publikováno v: Journal of Materials Science. 27:313-318

Preparation of an SnO2 semiconducting powder doped with antimony (x=2.38 mol%) was achieved by co-precipitation. The unit cell parameters of the doped SnO2 powders were measured and their changes with dopant concentration were determined. Four-point
