High activity of Pt4Mo alloy for the electrochemical oxidation of formic acid
(Amer Chemical Soc, Washington, 2007)
Surface processes on Pt4Mo alloy well-defined by X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD) were studied in acid solution by cyclic voltammetry. It was established that Mo in the alloy is much more ...
Numerical method for the prediction of bending properties of glass-epoxy composites / Primena numeričkog modela za predviđanje savojnih svojstava staklo-epoksi kompozitnog materijala
(Faculty of Technology, Novi Sad, 2007)
Mechanical properties of composite materials are conditioned by their structure and depend on the characteristics of structural components. In this paper is presented a numerical model by which the bending properties can ...
Removal of volatile organic compounds from activated carbon by thermal Desorption and catalytic combustion
(Maik Nauka/Interperiodica/Springer, New York, 2007)
The thermal desorption of saturated activated carbon discharged from an industrial adsorber and catalytic oxidation of desorbed products over a Pt/Al2O3 catalyst were investigated. The activated carbon is almost completely ...
Synthesis and sintering of Cu-Al2O3 nanocomposite powders produced by a thermochemical route
(Savez inženjera metalurgije Srbije, Beograd, 2007)
By hydrometallurgy and powder metallurgy along with prognosis of physical-chemical properties, a synthesis of new improved materials can be successfully performed with in advance pre-set properties which is conditioned by ...
Contribution of lactic acid fermentation to improved nutritive quality vegetable juices enriched with brewer's yeast autolysate
(Elsevier Sci Ltd, Oxford, 2007)
Vegetables are rich sources of the biologically active compounds which have beneficial effects in prevention of some diseases and certain types of cancer. From the point of view of protection and health, the objective of ...
Amino-functionalized glycidyl methacrylate based macroporous copolymers as metal ion sorbents
(Nova Science Publishers, 2007)
Four samples of macroporous crossliaked poly(glycidyl methacry late-co-ethy lene glycol dimethacrylate), poly(GMA-co-EGDMA), were synthesized by suspension copolymerization and functionalized by ring-opening reaction of ...
Nuclear and Other Instrumental Analytical Techniques in Investigation of Cultural Heritage: Complementarity and Competitivity
(Srpsko hemijsko društvo, 2007)
Nuclear analytical techniques (NATs), including INAA. XRF, PIXE, stable and radioisotopes, a, B, y-spectrometry, AMS, etc. have been applied to a wide range of cultural heritage materials with varying success. NATs featuring ...
Effect of silane coupling agents on mechanical properties of Nano-SiO2 filled high-density polyethylene composites
(Zurich : Trans Tech Publications, 2007)
Composites with nano-SiO2 particles and high density polyethylene (HDPE) matrix were produced by hot pressing with various particle contents and particle surface treatment using commercially available silane coupling agents: ...
Numerical and analytical modeling of elastic-plastic fracture mechanics parameters
(8th Conference of the Yugoslav Materials Research Society, 2007)
Structural integrity and service reliability depend on the fracture resistance of a material. Cracks in the material are the locations of stress concentration, and elastic-plastic deformation can occur causing the development ...
Solvent and structural effects on the kinetics of the reactions of 2-substituted cyclohex-1-enylcarboxylic and 2-substituted benzoic acids with diazodiphenyl with diazodiphenylmethane
(Wiley, Hoboken, 2007)
The rate constants for the reaction of 2-methyl-cyclohex-1-enylcarboxylic, 2-phenylcyclohex-1-enylcarboxylic, and 2-methylbenzoic and 2-phenylbenzoic acids with diazodiphenyl-methane were determined in 14 various solvents ...
