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 effect of resin concentration and electrodeposition bath temperature on the corrosion behaviour of polymer-coated steel
(Progress in Organic Coatings, 1990)
A.C. impedance measurements carried out on epoxy-resin electrocoated steels have been used to determine the pore resistance, capacitance and relative permittivity of the organic films. The time dependence of these ...
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 ...
Analysis of mass transfer in beer dialysis and diafiltration with two different membranes
(Serbian Chemical Society, Belgrade, 1996)
Experimental investigation of selective alcohol removal from beer by dialysis and dialysis with transmembrane pressure (diafiltration), using two different hollow-fiber membranes: Cuprophan (regenerated cellulose) and ...
Electrooxidation of H-2, CO and H-2/CO mixtures on a well-characterized Pt-Re bulk alloy electrode and comparison with other Pt binary alloys
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
We report new results for the electrooxidation of Hz, CO and H-2/CO mixtures on a Pt75Re25 bulk alloy using surface preparation in a UHV chamber and characterization by X-ray photoelectron spectroscopy (XPS). Sputter-cleaned ...
