Hydrogen desorption from nanostructured magnesium hydride composites
(Hemijska industrija, 2007)
The influence of 3d transition metal addition (Fe, Co and Ni) on the desorption properties of magnesium hydride were studied. The ball milling of MgH2-3d metal blends was performed under Ar. Microstructural and morphological ...
The distinctiveness of measuring interlaminar fracture toughness by the mode I method
(Hemijska industrija, 2007)
Practical problems in measuring the interlaminar fracture toughness by the mode I method were pointed out in this paper. Unidirectional carbon fibre/epoxy resin composite was used in the experiments (as the test material). ...
Thermal memory effects to photothermal pulse response
(Hemijska industrija, 2007)
An analytical model that describes surface temperature variations of media with thermal memory stimulated by laser pulses was developed. The influence of thermal memory for semi-infinite sample was analyzed by comparing ...
Application of inverse gas chromatography for polymer characterization
(Hemijska industrija, 2007)
The possibility of polymer characterization by inverse gas chromatography (IGC) was illustrated with the study of sorption properties of macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate), ...
Biocompatible and bioadhesive hydrogels based on 2-hydroxyethyl methacrylate, monofunctional poly(alkylene glycol)s and itaconic acid
(Hemijska industrija, 2007)
New types of hydrogels were prepared by the radical copolymerization of 2-hydroxyethyl methacrylate, itaconic acid and four different poly(alkylene glycol) (meth)acrylate components (Bisomers) in a water/ethanol mixture ...
Thermal properties of radiolytically synthesized PVA/Ag nanocomposites
(Hemijska industrija, 2007)
The radiolytic method was used to synthesize two types of nanocomposites with silver, PVA/Ag by film casting and PVA hydrogel/Ag nanocomposites. This method is particularly suitable for generating metal nanoparticles in ...
Dispersion and deagglomeration of nano-SiO2 particles with a silane modification reagent in supercritical CO2
(Hemijska industrija, 2007)
The supercritical. CO2 method was used in order to perform deagglomeration and improve the dispersion of nano-SiO2 particles. gamma-Methacryloxypropyltrimethoxysilane was used as the surface modification reagent. The ...
Kinetic investigation of the immobilization of chromotropic acid derivatives onto anion exchange resin
(Hemijska industrija, 2007)
The adsorption kinetics of pyrazol- (PACA) and imidazol-azo-chromo-tropic acid (IACA) onto Dowex 1-X8 resin, as a function of the dye concentration and temperature were investigated at pH 4.5. The pseudo-first- and ...
Synthesis of biomorphaus SiC-ceramics
(Hemijska industrija, 2007)
The carbothermal reduction processing of partially mineralized fir (Abies alba) samples was used to obtain highly-porous SiC ceramics with cellular structure. The infiltration of TEOS (tetraetilortosilikat, Si(OC2H5)(4)) ...
Zn-Mn-O: Ferromagnet at room temperature / Zn-Mn-O - feromagnetik na sobnoj temperaturi
(Hemijska industrija, 2007)
Semiconductor Zn-Mn-O crystallites were synthesized by a solid state reaction method starting from the thermal decomposition of the appropriate oxalates. Samples were thermally treated in air at temperatures ranging from ...
