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 ...
Selection of Calculation Method for Temperature Distribution in 99 Mass-% Al 2 O 3 Refractories
(Verlag Schmidt GmbH, 1998)
Refractories are constantly exposed to temperature changes. In most cases this exposure causes damage. In this work, attention is paid to problems of non-steady-state heat transfer. Some analytical and numerical methods ...
Synthesis, morphology, and formation mechanism of mullite particles produced by ultrasonic spray pyrolysis
(Cambridge Univ Press, New York, 1996)
Submicrometer spherical particles of mullite powder were synthesized by ultrasonic spray pyrolysis of emulsion and solutions, using tetra-ethyl-orthosilicate (TEOS) or silicic-acid and Al(NO3)(3) . 9H(2)O as initial ...
Reaction of a new thiol cationic surfactant with bunte salt in wool fibers
(Textile Research Inst, Princeton, 1997)
A new, effective, specific quaternary ammonium compound, N-dodecyl-amino-betaine-2-mercaptoethylamine hydrochloride (DABM), is synthesized to confer permanent characteristics (antimicrobial properties, improved dyeing and ...
Underpotential deposition of lead on Pt(111) in perchloric acid solution: RRDPt(111)E measurements
(Amer Chemical Soc, Washington, 1997)
Underpotential deposition (UPD) of lead (Pb-upd) on Pt(111) in perchloric acid solution was studied using the rotation ring disk, electrode (RRDPt(111)E) method for measurements of the Pb2+ ion-specific flux. The total ...
Rhizopus arrhizus lipase-catalyzed interesterification of the midfraction of palm oil to a cocoa butter equivalent fat
(Elsevier Science Inc, New York, 1993)
Celite-immobilized lipase from Rhizopus arrhizus was used to interesterify triacylglycerols of the palm oil midfraction with stearic acid in n-hexane. Under optimum conditions, acyl exchange occurred mainly between the ...
The thermal degradation kinetics of poly(chlorethylmethacrylates)
(John Wiley & Sons Ltd, W Sussex, 1992)
The thermal degradation kinetics of poly(2-mono-, 2,2-di- and 2,2,2-trichlorethyl methacrylate) and of the non-chlorinated poly(ethyl methacrylate) were studied by TG in the absence and presence of oxygen. The overall ...
The determination of the corrosive behavior of polymer-coated steel with A.C. impedance measurements
(Pergamon-Elsevier Science Ltd, Oxford, 1990)
A.C. impedance measurements have quantitatively determined the pore resistance, capacitance and relative permittivity of organic films on epoxy-resin coated steels. The time dependence of these characteristics of protective ...
The thermal degradation kinetics of dextran and pullulan
(John Wiley & Sons Ltd, W Sussex, 1993)
The effect of molar mass and, in the case of dextran, of the degree of branching on the thermal degradation kinetics of dextran and pullulan was studied in the presence and absence of oxygen. Although the initial mass loss ...
