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 ...
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 ...
Kinetic properties of the Ti-Ni intermetallic phases and alloys for hydrogen evolution
(Elsevier Science Sa, Lausanne, 1997)
The kinetics and mechanism of hydrogen evolution at Ti-Ni alloy electrodes prepared by are-melting and mechanical alloying methods has been studied by means of AC impedance spectrum measurements. The electrode, prepared ...
The thermal degradation of polymethacrylonitrile with different end groups
(Springer, Dordrecht, 1997)
Polymethacrylonitrile (PMAN) was prepared by bulk, solution and precipitation polymerization. The thermal stability of the polymer, which is affected by the structure of the chain end groups, was studied by non-isothermal ...
Reversed substituent effect on C=O stretching vibrations in hydantoin derivatives
(Natl Inst Science Communication & Information Resources-Niscair, New Delhi, 1997)
The infrared spectra have been recorded for thirteen 3-substituted-5,5-dimethylhydantoins in the region of fundamental C=O stretching vibrations in dichloromethane. The frequencies of symmetric and asymmetric C=O stretching ...
The effect of deposition process exchange current density on the thin metal film formation on inert substrate
(Serbian Chemical Society, Belgrade, 1997)
The initial stage of thin surface metal film formation on inert substrate is considered. The simultaneous action of both active centers and nucleation exclusion zones was taken into consideration when discussing the ...
Structural investigation of the chabazite like aluminophosphate prepared in the presence of HF.
(Amer Chemical Soc, Washington, 1997)
Quantum approach to GaAs MESFETs
(IEEE, 1997)
This paper is completely devoted to an original method of determination of carriers distribution in GaAs MESFET channel based on the investigation of transport equation including a quantum correction term.
Preparation of thermoplastic starch
(Serbian Chemical Society, Belgrade, 1997)
Native starch and WX-starch, i.e., native starch enriched with amylopectin, were mixed with plasticizers and thermomechanically treated in a twin screw mixer in order to obtain thermoplastic starch. Ethylene glycol, propane ...
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 ...
