Oxygen reduction on a duplex stainless steel
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
O-2 reduction on duplex stainless steel was investigated in neutral and alkaline solutions with and without the presence of chloride ions. All polarization curves showed hysteresis with higher reaction rate in positive ...
The thermal degradation of some alkali metal salts of poly(itaconic acid)
(Springer, Dordrecht, 1997)
The Li-, Na- and K salts of poly(itaconic acid) (PIA) were prepared by treating the polyacid with the corresponding aqueous hydroxide. The resulting polysalts were analysed by elemental analysis, FTIR spectroscopy and ...
The potential of piezoelectric sensors for characterization of activated carbon cloth applied in adsorption of phenols from air
(Amer Chemical Soc, Washington, 1998)
Characterisation of activated carbon cloth (ACC) applied for phenols adsorption from the air was performed by a pair of coated piezoelectric quartz crystals as sensors. ACC cloth was impregnated with specific organic ...
Surface electrochemistry of CO on Pt(110)-(1x2) and Pt(110)-(1x1) surfaces
(Elsevier Science Bv, Amsterdam, 1997)
A new type of flame-annealing method has been developed for the preparation of surfaces having either fcc(110)-(1x1) or fcc(110)-(1 x 2) symmetry. In situ X-ray scattering studies show that both the Pt(110)-(1 x 2) and ...
Underpotential deposition of lead on Pt(111) in the presence of bromide: RRDPt(111)E and X-ray scattering studies
(Elsevier Science Sa, Lausanne, 1998)
The underpotential deposition (upd) of Pb onto Pt(lll) in solution containing Br- was examined by classical RRDP(111)E electrochemical methods in combination with in situ surface X-ray scattering measurements. The results ...
Electrooxidation of H-2/CO mixtures on a well-characterized Pt75Mo25 alloy surface
(Amer Chemical Soc, Washington, 1997)
The electrochemical oxidation of hydrogen in the presence of carbon monoxide (0.05-2%) on a well-characterized Pt75Mo25 alloy surface was examined using the rotating disk electrode technique in 0.5 M H2SO4 at 333 K. The ...
Analysis of mass transfer in beer diafiltration with cellulose-based and polysulfone membranes
(Elsevier, Amsterdam, 1997)
An experimental investigation of beer dialysis with transmembrane pressure (diafiltration) was performed using two different hollow-fibre membranes: cuprophane (regenerated cellulose) and polysulfone for different flow ...
Relationship between fracture resistance and critical temperature difference in ceramic materials
(Plenum Publ Corp, New York, 1997)
The resistance of ceramics to thermal shock can be characterized using either a parameter of their resistance to fracture R or the critical temperature difference Delta T-c = Delta T-c (Bi). It is demonstrated that a ...
Regulation of the crystallization in a crucible furnace
(Elsevier, Amsterdam, 1999)
A model of an air cooler ("cold finger") in a laboratory crucible furnace, for simultaneous regulation of scaling intervals of the crystallization rate in a series of Tamman test tubes with the purpose of obtaining crystals, ...
O2 reduction on on ink-type rotating disk electrode using Pt supported on high-area carbons
(Electrochemical Soc Inc, Pennington, 1998)
The kinetics of O2 reduction has been examined on an ink-type electrode made with Pt supported on high-area carbon. Electrocatalysls with 5-40 mass % of Pt on Black Pearls, Vulcan XC-72, and Shawinigan acetylene black ...
