Effect of chemisorbed carbon monoxide on Pt/C electrode on the mechanism of the hydrogen oxidation reaction
(Elsevier, 2009)
The influence of poisoning of Pt catalyst by CO on the kinetics and mechanism of H2 oxidation reaction (HOR) at Pt/C electrode in 0.5 mol dm-3 HClO4, saturated with H2 containing 100 ppm CO, was examined with rotating disc ...
Manganese-containing silica-based microporous molecular sieve MnS-1: Synthesis and characterization
(Amer Chemical Soc, Washington, 2003)
Manganese-containing silicalite-1 (MnS-1) was synthesized hydrothermally in the presence of the structure-directing agent (template) tetraethylammonium hydroxide (TEAOH) for the first time. The highly crystalline MnS-1 ...
Polymerization of Itaconic Acid Initiated by a Potassium Persulfate/N,N-Dimethylethanolamine System
(Wiley, Hoboken, 2008)
The synthesis and characterization of poly (itaconic acid) (PIA) with a novel initiator/activator system is presented. The initiator in this system was potassium persulfate, whereas the activator was N,N-dimethylethanolamine ...
Detecting aniline in air in systems based on piezoelectric quartz crystal resonators modified with poly(ethylene glycol succinate) under static and dynamic conditions
(Journal of Analytical Chemistry, 2000)
The optimal conditions have been found for aniline sorption on a film of poly(ethylene glycol succinate) by the piezoelectric quartz crystal microbalance method using bulk acoustic wave sensors based on AT-cut quartz ...
Physical-mechanical phenomenon of woven and non-conventional materials
(Emerald Group Publishing Limited, Bradford, 2000)
The basic idea of this project is in developing series of methods for monitoring structural parameters, as well as establishing their relation with the behaviour of woven and non-woven materials. Establishing the connection ...
The effect of temperature on strain-rate sensitivity in high strength Al-Mg alloy sheet
(Elsevier Science Sa, Lausanne, 2002)
Comprehensive experimental work performed to assess the temperature and strain-rate affected deformation behaviour of commercial AlMg6 type, 1.0 mm thick annealed sheet. Elevated temperature tension test performed at ...
Approach to laminar phenomena occurring on external and internal surfaces of solid specimens
(Kluwer Academic Publishers, 2000)
This article presents a general mathematical model for describing the laminar transport phenomena during homogeneous/heterogeneous appearances in the neighborhood of external and internal surfaces of small solid specimens. ...
Electrospray mass spectrometric studies of a potential antitumor drug and its analogous platinum(II) and platinum(IV) complexes with the ethylenediamine-N,N '-di-3-propanoato ligand and its dibutyl ester
(Springer Wien, Wien, 2009)
The electrospray mass spectrometric (ESI-MS) behavior of the complexes trans-dichloro(ethylenediamine-N, N'-di-3-propionato) platinum(IV), trans-dibromo(ethylenediamine-N, N'-di-3-propionato) platinum( IV), dichloro ...
A two-step, three-component queuing cascade leading to dihydrobenzoxepine and dihydrobenzazepine derivatives
(Wiley-Blackwell, 2007)
A palladium-catalyzed reaction of methylenespiropentane (11) with iodobenzene (12) under typical Heck conditions [Pd(OAc)2, PPh 3, Et3N, DMF] produced a mixture of the unstable [3]dendralene 13 and allylidenecyclopropane ...
Influence of different iron powders on the friction properties of sintered friction materials based on iron
(Elsevier Science B.V., 2000)
The possibility of using iron powders of different morphological, chemical and physical properties as the bases of the metal matrix of the friction layer in sintered friction materials for dry friction under severe braking ...
