In this article, we want to draw attention to the hysteron-magmatic origin of titanium-magnetite ores of the Tibinbulak gabbro-peridotite complex located in the northwestern part of the Sultan-Uvais ridge. Which is the only outlet of the Phanerozoic found... see more

The method temperature-programmed desorption has been studied the state of toluene on the surface-modified vanadium catalysts on different carriers. Among the investigated carriers the most active in the reaction of partial oxidation of toluene is anatase... see more

To shorten the biological treating time and to examine the effect of electrolytes in a model water on the photocatalytic treatment, the combined biological-photocatalytic treatment was evaluated for removal of a mixture (total: 100 mg L-1, each: 25 mg L-1... see more

Vanadium oxide supported on the surface of titanium silicalite was investigated in benzene hydroxylation to determine its activity as heterogeneous catalyst. Effect of vanadium loading on structure and activity of titanium silicalite was investigated. On ... see more

Complex investigations of physical and chemical properties of wastes of thermal power plants burning fuel-oil were carried out. The phase relations in model systems V2O5–NiO (MgO)–CaO–Na2O and solubility of the major phases formed at heat treatment were s... see more

The present work is dedicated to investigation of vanadium xerogels deposited on titanium oxide for the oxidation process of o-xylene by hydrogen peroxide under the mild conditions. The structure of deposited vanadium catalyst and sizes of vanadium xeroge... see more

In the contact metamorphic aureole of the Duluth Complex, Cu-Ni-PGE mineralization occurs locally up to 100 m from the intrusion-footwall contact (Spruce Road area), whereas elsewhere (Dunka Pit deposit) the footwall granite and metapelite (Serpentine dep... see more

The method of x-ray diffractometry was used to study the effect of the composition of two, three, four and five elemental niobium-based alloys on their phase-structural state, average crystallite size, and thermal expansion coefficient in the temperature ... see more

Navas, A. P. Flores-Romero, S. Sanchez-Moreno, J. A. Camargo, and E. C. McGawley. 2010. Effects of heavy metal soil pollution on nematode communities after the Aznalcollar mining spill. Nematropica 40:13-29. In 1998, the rupture of a mining reservoir cont... see more
