Effect of test variables on apparent activation energy for hot working and critical recrystallization temperatures of V-microalloyed steel
(Verlag Stahleisen Mbh, Dusseldorf, 1997)
The effect of test variables on the apparent activation energy for hot working of a medium carbon V-microalloyed steel, Q(HW), and the critical recrystallization temperature, T-nr, have been studied by means of isothermal ...
Leaching kinetics of lead from lead (II) sulphate in aqueous calcium chloride and magnesium chloride solutions
(Elsevier Science Bv, Amsterdam, 1997)
The kinetics of lead leaching from lead (II) sulphate in aqueous calcium chloride and magnesium chloride solutions was studied. The leaching rates of lead were measured by using an agitated vessel at atmospheric pressure, ...
Thermal shock of ceramic material : Comparison of resistance parameter with the critical ΔT values ΔTc = ΔTc(Bi) of ceramic materials
(Trans Tech Publications Ltd., 1997)
Thermal shock resistance of ceramic material can be characterized by using resistance parameters or critical temperature difference. Correlation between fracture resistance parameter, R and critical temperature difference, ...
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 ...
Application of a chitosan/nonionic surfactant mixture to wool assessed by dyeing with a reactive dye
(Society of Dyers and Colourists, 1997)
Chitosan application to wool is known to be associated with problems such as its weak binding and uneven distribution. In an attempt to overcome such problems, chitosan was applied from a mixture with a nonionic surfactant. ...
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 ...
Effect of convective mass transfer on beer diafiltration
(Inst Brewing, London, 1997)
The industrial application of dialysis for the de-alcoholization of beer is based on a diafiltration method, because a small positive transmembrane pressure an the beer side of the membrane is necessary to prevent ingress ...
The thermal degradation kinetics of isomeric poly(dipropyl, itaconates)
(Springer, Dordrecht, 1997)
Non-isothermal thermogravimetry was performed in a dynamic nitrogen atmosphere, on a series of poly(di-n-propyl itaconates) (PDnPI) and poly(di-iso-propyl itaconates) (PDiPI) which had been prepared in the presence of ...
Boron and phosphorus doped glassy carbon: I. Surface properties
(Pergamon-Elsevier Science Ltd, Oxford, 1997)
The effects of boron and phosphorus incorporation in phenolic resin precursor on the surface properties of glassy carbon (GC) have been studied. Characterization of the surface properties using X-ray photoelectron spectroscopy ...
Polymeric and immobilized crown compounds, material for ion separation
(Pergamon-Elsevier Science Ltd, Oxford, 1997)
We describe the synthesis of ionoselective polymers bearing different pendant crown ethers. The synthesis was applied to various macrocycles. We discuss the influence of macrocyclic cavity Size and rigidity of the polymers ...
