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 ...
Method for quantitative analysis of glycosaminoglycan distribution in cultured natural and engineered cartilage
(Amer Inst Physics, Woodbury, 1999)
Cartilage tissue engineering can provide a valuable tool for controlled studies of tissue development. As an example, analysis of the spatial distribution of glycosaminoglycans (GAG) in sections of cartilaginous tissues ...
CdS nanoclusters: Synthesis, characterization, size dependent oscillator strength, temperature shift of the excitonic transition energy, and reversible absorbance shift
(Journal of Physical Chemistry, 1994)
Improved synthetic routes and size-selective precipitation have enabled the preparation of almost monodisperse CdS clusters. Six samples of 1-thioglycerol stabilized clusters with diameters of approximately 13, 14, 16, 19, ...
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 ...
Corrosion protection of mild steel by polypyrrole coatings in acid sulfate solutions
(Pergamon-Elsevier Science Ltd, Oxford, 1997)
The corrosion behaviour of mild steel covered by the electrodeposited polypyrrole films was investigated by electrochemical impedance spectroscopy. Electrodeposition of polypyrrole was performed from aqueous solution of ...
Hydrogen evolution at Zn-Ni alloys
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
Zn-Ni alloys were electrodeposited from a berate-citrate and TEPA bath in potentiostatic and galvanostatic regimes. Potential of electrodeposition or current density were varied and chemical composition and phase structure ...
The influence of polypyrrole films on the corrosion behavior of iron in acid sulfate solutions
(Elsevier Science Sa, Lausanne, 1998)
The corrosion behavior of mild steel covered by electrodeposited polypyrrole films was investigated by electrochemical impedance spectroscopy. Electrodeposition of polypyrrole was performed from an aqueous solution of ...
Flow regimes and liquid mixing in a draft tube gas-liquid-solid fluidized bed
(Pergamon-Elsevier Science Ltd, Oxford, 1992)
Flow behavior of gas bubbles, liquid and particles, and mixing in the liquid phase were studied in draft and annulus of a draft tube gas-liquid-solid fluidized bed. The experimental unit was a 80mm ID × 1.5 m column with ...
