Structural effects in electrocatalysis: Formic acid oxidation at model and real Pt catalysts
(Trans Tech Publications Ltd, Durnten-Zurich, 2006)
Formic acid oxidation was studied at low-index Pt single crystals (model systems) as well as at the platinum catalyst supported on high area carbon (real catalyst) in HClO4. The Pt single crystals were characterized by ...
Modelling of plasma activated CVD of Co-C-O layers in parallel plate reactor
(Elsevier, 2006)
A modelling procedure for Co-C-O layers generated on steel C35 from cobalt(II) acetylacetonate by PACVD is suggested. The investigations were carried out in a parallel plate reactor, under a radio frequency (13.56 MHz) ...
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 ...
Uticaj pratećih komponenata vlakana konoplje na njihovu električnu otpornost / Influence of accompanying substances of hemp fibres on their electric resistance
(Savez hemičara i tehnologa Srbije, 2006)
U cilju iznalaženja zadovoljavajućeg postupka modifikovanja vlakana konoplje u ovom radu su prikazane zavisnosti između hemijskog sastava, finoće i električne otpornosti. Prema proceduri za određivanje hemijskog sastava ...
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 ...
Karakteristike kvašenja pletenina na bazi konoplje namenjenih za medicinske svrhe / Liquid wetting properties of hemp based knitted fabrics for hospital uses
(Savez inženjera i tehničara tekstilaca Srbije, 2006)
U okviru ovog rada pletenine na bazi konoplje podvrgnute su ispitivanju maksimalnog kapaciteta apsorpcije tečnosti kao i brzine njene apsorpcije. S obzirom da su za izradu pletenina upotrebljene nehomogene kompleksne pređe ...
The validity of the general similarity law for electrical breakdown of gases
(IOP Publishing Ltd, Bristol, 2006)
This paper investigates the validity of the similarity law in cases of dc and pulse breakdown of gases. Geometrically similar systems insulated with SF6 gas were used during experiments. It is shown that the similarity law ...
Saw surfacing of the worn part of crane wheel with flux cored wire / Navarivanje EPP-postupkom istrošenog dela točka dizalice primenom punjene žice
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2006)
This paper presents results of repairing a ring part and rolling surfaces of the crane wheel by SAW method with flux cored wire. Optimal quality of flux cored wire for crane wheel repairing is defined by weld metal hardness ...
Transition metal complexes with thiosemicarbazide-based ligands. LIII. [4-(2-Diphenylphosphino-a-ethoxybenzyl-κP)-S-methyl-1-(4-oxidopent-3-en-4- ylidene-κO)-thiosemicarbazido-κ 2 N 1 ,N 4 ]nickel(II)
(International Union of Crystallography, 2006)
The title compound, [Ni(C 28 H 30 N 3 O 2 PS)], crystallizes with two independent molecules in the asymmetric unit. The Ni II atoms are in significantly deformed square-planar environments formed by an ONNP donor set from ...
