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 ...
Investigation of enhanced CO tolerance in proton exchange membrane fuel cells by carbon supported PtMo alloy catalyst
(Electrochemical Soc Inc, Pennington, 1999)
We report a two- to threefold enhancement of CO tolerance in a proton exchange membrane (PEM) fuel cell, exhibited by carbon supported nanocrystalline PtMo/C as compared to the current state of the art PtRu/C electrocatalysts. ...
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 ...
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. ...
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 of nanostructured mullite from xerogel and aerogel obtained by the nonhydrolytic sol-gel method
(Pergamon-Elsevier Science Ltd, Oxford, 1999)
Synthesis and nanostructure evolution of mullite (3Al(2)O(3).2SiO(2)) from xero- and aerogels, obtained by the non-hydrolytic sol-gel process are described. Mullite crystallization and gel nanostructure evolution after ...
Reactivity of beta-aroylacrylic acids with diazodiphenylmethane (vol 63, pg 359, 1998)
(Srpsko hemijsko društvo, Beograd, 1999)
Corrosion protection of aluminium by a cataphoretic epoxy coating
(Elsevier Science Sa, Lausanne, 1999)
The corrosion behavior and thermal stability of epoxy coating electrodeposited on aluminium have been investigated during exposure to 3% NaCl. Electrochemical impedance spectroscopy (EIS), gravimetric liquid sorption ...
