A Study of the Mn, Co and Ni Environment in the As-synthesized and Rehydrated-calcined Aluminophosphate with Chabazite-like Topology
(Croatian Chemical Society, 1999)
Diffuse-reflectance spectroscopy (DRS), X-ray absorption near-edge structure (XANES) and extended X-ray absorption fine structure (EXAFS) methods are applied to an investigation of Mn, Co and Ni local environments in MnAlPO, ...
Room temperature deformation behaviour of A1Mg6.5 alloy sheet
(Carl Hanser Verlag, Munich, 1999)
Room temperature tensile test have been performed with initial strain rates of 6.7 x 10(-4) s(-1), 6.7 x 10(-3) s-(1) and 6.7 x 10(-2) s(-1), on AlMg6.5 alloy sheet, after imposing 5% to 70% cold rolling reductions, and ...
Thermal investigation of some chelate Ni(II) complexes
(Serbian Chemical Society, Belgrade, 1999)
Several diamine-nickel(II) complexes have been prepared and the kinetic parameters of their decomposition reactions investigated. The complexes undergo a gradual thermal decomposition. First, water is lost, followed by the ...
Multiaxial determination of the resistance to creasing of clothing wool fabrics
(Emerald Group Publishing Limited, Bradford, 1999)
In this paper, values of deformation components (elastic, viscoelastic, plastic) of clothing wool fabrics by measuring the crease recovery angle in various directions to the warp direction (0°-warp, 30°, 45°, 60°, and ...
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 ...
Corrosion behaviour of epoxy coatings electrodeposited on steel electrochemically modified by Zn-Ni alloy
(Pergamon-Elsevier Science Ltd, Oxford, 1999)
The corrosion behaviour and thermal stability of epoxy coatings electrodeposited on steel: phosphatised steel and steel previously modified by electrodeposited Zn-Ni alloy was investigated during exposure to 3% NaCl. The ...
Rheological study of the copolymerization reaction of acrylate-terminated unsaturated copolyesters with styrene
(Wiley-VCH Verlag Gmbh, Weinheim, 1999)
The free radical copolymerization reaction of three series of acrylate-terminated unsaturated polyesters with styrene, using benzoyl peroxide/N,N-dimethylaniline as the redox initiator system, was followed by dynamic ...
Modeling of nanostructural design of ultrafine mullite powder particles obtained by ultrasonic spray pyrolysis
(Pergamon-Elsevier Science Ltd, Oxford, 1999)
In this paper, a model of substructure design of mullite powder particles obtained by spray pyrolysis lit the field of ultrasound excitation is described. Based an this model, the size of subparticles (nanoparticles) ...
Investigation of the Microstructure and Distribution of Solute During Solidification of Al-Cu Alloy
(Springer Science and Business Media LLC, 1999)
Phenomenon of solidification process plays an important role in various areas like: crystal growth, casting processes, liquid phase sintering etc. Results presented in this paper contribute to investigation of the influence ...
Electrical resistance of cotton-metal fibre yarns
(Inst Chemical Fibres, Lodz, 1999)
Yarns representing cotton-metal fibre blends were studied. The electrical resistance of yarns including different fractions of cotton and metal fibres was compared with cotton yarns having the same nominal characteristics. ...
