The thermogravimetric analysis of some polysiloxanes
(Elsevier Ltd., 1998)
Thermogravimetric (TG) and differential thermogravimetric analyses (DTG) of some homo- and copolymers of dimethylsiloxane have been performed. The effect of the presence of hydrido-substituents and/or vinyl end-groups on ...
Sulphatization of manganese slime from zinc electrolysis with ferrosulphate
(Wiley, Hoboken, 1998)
The kinetics and mechanism of the sulphatization of manganese slime from the zinc electrolysis with Fe(ll) sulphate was studied. The priority of chemical reactions was determined on the basis of the results of thermodynamic ...
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. ...
Poly(dialkoxyethyl itaconates) .2. The thermal degradation of some poly(dialkoxyethyl itaconates)
(John Wiley & Sons Ltd, W Sussex, 1996)
The oxidative and non-oxidative degradation of poly(di-methoxy-), poly(di-ethoxy-), poly(di-iso-propoxy-) and poly(di-n-butoxyethyl itaconate) were investigated by thermogravimetry. Characteristic degradation temperatures ...
Poly(dialkoxyethyl itaconate)s-I. Some properties of dimethoxyethyl itaconate and its polymer
(Pergamon-Elsevier Science Ltd, Oxford, 1995)
The preparation of dimethoxyethyl itaconate and its polymerisation are described. Some of the properties of the monomer and polymer were determined with special emphasis on the experimental determination of the solubility ...
Local and overall mixing characteristics of the gas-liquid-solid air-lift reactor
(Amer Chemical Soc, Washington, 1994)
Local and overall mixing characteristics were studied for the gas-liquid-solid reactor operating with an internal draft tube and low-density particles. The experimental reactor had a working volume of 7.6 L, column diameter ...
Thermal shock of ceramic material : Damage resistance parameters and critical flaw size
(Trans Tech Publications Ltd., 1997)
The alumina refractories used in this study included a serias of 12 commertial products (two fireclay and ten high alumina brands ) containing ≈ 45 - 90 % Al2O3. Damage resistance parameters R,, R, and RSt were used in ...
The potential of the piezoelectric sensor for the characterization of activated carbon cloth applied in the adsorption of phenol from air
(Amer Chemical Soc, Washington, 1996)
Effect of temperature on surface processes at the Pt(111)-liquid interface: Hydrogen adsorption, oxide formation, and CO oxidation
(Amer Chemical Soc, Washington, 1999)
The variation of the adsorption pseudocapacitance with temperature is used to obtain the enthalpy, entropy, and free energies of adsorption of H-upd and OHad on Pt(lll) as a function of pH and nature of the anion of the ...
Effect of interpass time and cooling rate on apparent activation energy for hot working and critical recrystallization temperature of Nb-microalloyed steel
(Iron Steel Inst Japan Keidanren Kaikan, Tokyo, 1999)
Two-stage linear In[sinh(alpha sigma)] vs. 1/T relations indicative of double Q(HW) behavior, are obtained from anisothermal multipass flow curves generated by testing Nb/Ti microalloyed steel in torsion tin the range ...
