Simultaneous presentation of VLE, H-E and c(p)(E) by the PRSV equation of state with the modified van der Waals one-fluid and Huron-Vidal-Orbey-Sandler mixing rules
(Elsevier, Amsterdam, 1999)
The Stryjek-Vera modification of the Peng-Robinson equation of state with two parameter van der Waals one-fluid mixing rule suggested by Schwartzentruber and Renon (SR) and the Orbey-Sandler modification of the Huron-Vidal ...
Oxygen reduction reaction on Pt(111): effects of bromide
(Elsevier Science Sa, Lausanne, 1999)
Using the rotating ring-disk technique (RRDE) the oxygen reduction reaction (orr) was studied on the Pt(111) surface in the presence of Br- anions. We found that the orr at the Pt(111) \ Br-ad interface is always accompanied ...
The electro-oxidation of H-2 and H-2/CO mixtures on carbon-supported PtxMoy alloy catalysts
(Electrochemical Soc Inc, Pennington, 1999)
Electro-oxidation kinetics of H-2 and H-2/CO mixture were studied on bimetallic Pt-Mo catalysts supported on a high-surface-area carbon black. The Pt:Mo atomic ratios in the catalysts were 3:1 and 4:1. Characterization of ...
C-13 NMR spectra of pyridine chalcone analogs
(Elsevier, Amsterdam, 1999)
C-13 NMR spectra of two series of pyridine chalcone analogs were determined in deuterated dimethylsulphoxide (DMSO-d(6)). It was established that these compounds were in more stable E-configurations except for the ...
Effect of turbulent Schmidt number on mass-transfer rates to falling Liquid films
(Amer Chemical Soc, Washington, 1999)
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 ...
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 ...
Synthesis and properties of hydroxyapatite/poly-L-lactide composite biomaterials
(Elsevier Sci Ltd, Oxford, 1999)
Calcium hydroxyapatite (HAp) and poly-L-lactide (PLLA) were synthesized chemically. The obtained HAp was of high purity and, after special thermal treatment, of high crystallinity as well. Synthesis of PLLA was performed ...
Surface electrochemistry of CO and H-2/CO mixtures at Pt(100) interface: Electrode kinetics and interfacial structures
(Amer Chemical Soc, Washington, 1999)
The Pt(100)-CO interaction in aqueous electrolytes was examined by using rotating disk methods in combination with in-situ surface X-ray scattering (SXS) measurements. The analysis of the SXS results indicates that the ...
Shrinkage properties of wool treated with low temperature plasma and chitosan biopolymer
(Textile Research Inst, Princeton, 1999)
Low temperature plasma treatments of wool modify only the cuticle surface of the fibers, improving their surface wettability, dyeability, fiber cohesion, and shrink resistance. The shrink-resist properties obtained with ...
