A kinetic study of the thermal degradation of ammonium species inside a 3D zincophosphate
(Elsevier Science Bv, Amsterdam, 2006)
Ammonium ions remain inside the 3D zincophosphate framework after the hydrothermal crystallization. These species in co-operation with sodium cations exert a specific templating role in the formation of the open-framework ...
Morphology, internal structure and growth mechanism of electrodeposited Ni and Co powders
(Springer, New York, 2006)
In this paper the morphology (SEM analysis), the internal structure (cross-section analysis) and the growth mechanism of Ni and Co powders electrodeposited from ammoniacal electrolyte are investigated. It is shown that ...
Isolation of essential oil and supercritical carbon dioxide extract of Juniperus communis L. fruits from Montenegro
(John Wiley and Sons Ltd, 2006)
Ripe fruits (berries) of common juniper (Juniperus communis L.) from northern Montenegro were extracted by hydrodistillation and by supercritical carbon dioxide (SC-CO2) in a single-stage separation system. The composition ...
On a possible role of dicarboxylate ions in the formation of open-framework metallophosphates
(Croatian Chemical Society, 2006)
Three dicarboxylic acids (oxalic, malonic and terephthalic) were investigated as possible pillars in the formation of metallophosphates with extended structures in the presence of 1,2-diaminopropane (DAP) as a structure-directing ...
An evidence for a chain to network transformation during the microwave hydrothermal crystallization of an open-framework zinc terephthalate
(Springer, Dordrecht, 2006)
A 3-D open-framework and a chain-structured zinc terephthalate are obtained by hydrothermal crystallization under microwave heating at 180 degrees C. The study shows that these structures have rather similar principal ...
The effect of TiO 2 on the structure and devitrification behavior of potassium titanium germanate glass
(Springer Netherlands, 2006)
The effect of replacing 20 mol% of GeO 2 by TiO 2 on the properties of potassium germanate glass was investigated. The structure and devitrification behaviour of glasses were studied by Fourier transform infrared spectroscopy ...
