The thermal degradation of some isomers of poly(di-butyl itaconates)
(Elsevier, Amsterdam, 1999)
The non-oxidative and oxidative thermal degradation of poly(di-iso-butyl itaconate) (PDiBI), poly(di-n-butyl itaconate) (PDnBI), and poly(di-sec-butyl itaconate) (PDsBI) were studied by following changes in the polymer ...
EXAFS and XANES study of the incorporation of Mn cations into a chabazite-like AlPO molecular sieve
(Int Union Crystallography, Chester, 1999)
The incorporation of Mn(II) cations into a chabazite-like MnAlPO material is studied with Mn K-edge XANES and EXAFS. Both methods show that Mn(II) is inserted exclusively into the tetrahedrally coordinated aluminum sites. ...

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 ...
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 ...
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 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 ...
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 ...
Electrooxidation of CO and H-2/CO mixtures on Pt(111) in acid solutions
(Amer Chemical Soc, Washington, 1999)
Electrocatalysis of CO oxidation and the interfacial structure of the CO adlayer (COad) on the Pt(111) surface in 0.5 M H2SO4 were examined by using the rotating disk electrode method in combination with in situ surface ...
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 ...
