Oxygen reduction reaction on Pt(111): effects of bromide
(Elsevier Science Sa, Lausanne, 1999)
Using the rotating ring-disk technique (RRDE) the oxygen reduction reaction (orr) was studied on the Pt(111) surface in the presence of Br- anions. We found that the orr at the Pt(111) \ Br-ad interface is always accompanied ...
Formability of a high-strength Al Mg6.8 type alloy sheet
(Springer, New York, 1998)
Room temperature formability testing was performed on an AlMg6.8 type alloy sheet with a fully recrystallized structure (average grain diameter similar to 18 mu m) and after partial annealing with a retained deformed ...
Hydrogen evolution at Zn-Ni alloys
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
Zn-Ni alloys were electrodeposited from a berate-citrate and TEPA bath in potentiostatic and galvanostatic regimes. Potential of electrodeposition or current density were varied and chemical composition and phase structure ...
Kinetics of lipase-catalyzed hydrolysis of palm oil in lecithin/izooctane reversed micellles
(Springer, New York, 1998)
Candida rugosa lipase has been used to investigate the hydrolysis of palm oil in a lecithin/isooctane reversed micellar system. The reaction obeys Michaelis-Menten kinetics for the initial conditions. Kinetic parameters ...
The use of chitosan on hydrogen peroxide pretreated wool
(Amer Assoc Textile Chemists Colorists-Aatcc, Res Triangle Pk, 1998)
Since chlorination is known to produce substantial pollution with adsorbable organo halogens (AOX) in textile wastewater, shrink resist treatments like the widely used chlorine/Hercosett process are no longer environmentally ...
Hydridic and electrocatalytic properties of hypo-hyper-d-electronic combinations of transition metal intermetallic phases
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
Hydridic and electrocatalytic properties of hypo-hyper-d-electronic combinations of transition metals in their intermetallic phases and alloys for the hydrogen storage, hydridic batteries and its electrode reactions (HELR) ...
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 ...
Characterization of natural isolate Lactobacillus acidophilus BGRA43 useful for acidophilus milk production
(Wiley, Hoboken, 1998)
Lactobacillus acidophilus BGRA43 was selected from a set of human origin isolates of Lact. acidophilus strains for the highest growth rates and antagonistic effect against both Gram-positive and Gram-negative bacteria. The ...
UPD of Cu on Pt(100): effects of anions on adsorption isotherms and interface structures
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
The results presented in this study show definitely that copper deposition in perchloric acid is a very slow, kinetically controlled process. In nearly halide free supporting electrolytes du appeared to be deposited at ...
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, ...
