Characterization of a surface modified carbon cryogel and a carbon supported Pt catalyst
(Journal of the Serbian Chemical Society, 2007)
A carbon cryogel, synthesized by carbonization of a resorcinol/formaldehyde cryogel and oxidized in nitric acid, was used as catalyst Support for Pt nanoparticles. The Pt/C catalyst was prepared by a modified polyol synthesis ...
The alcoholysis of 1,2,2-trimethylpropyl-methylfluorophosphonate / Alkoholiza 1,2,2-trimetilpropil-metilfluorofosfata
(Serbian Chemical Society, Belgrade, 2000)
The alcoholysis of 1,2,2-trimethylpropyl-methylfluorophosphonate (soman) was examined with a series of alkoxides and in corresponding alcohols: methanol, ethanol, 1-propanol, 2-propanol, 2-methoxyethanol and 2-ethoxyethanol. ...
The effect of electrodeposition process parameters on the current density distribution in an electrochemical cell
(Serbian Chemical Society, 2001)
Cell voltage - current density dependences for a model electrochemical cell of fixed geometry were calculated for different electrolyte conductivities, Tafel slopes and cathodic exchange current densities. The ratio between ...
Synthesis and characterization of thermoplastic copolyester elastomers modified with fumaric moieties
(Serbian Chemical Society, 2001)
A series of poly(ether-ester)s derived from dimethyl terephthalate (DMT), dimethyl fumarate (DMF), 1,4-butandiol (BD) and poly(tetramethylene oxide) (PTMO, M̄n = 1000 g/mol) was synthesized in a two stage process involving ...
The effect of organic molecules adsorption on hydrogen absorption in relation to the hydrogen evolution reaction
(Serbian Chemical Society, 2001)
The competitive adsorption of organic molecules (2, 7-naphthalenedisulfonic acid) and adsorbed H is of interest in relation to its influence on H absorption into a Pd-Ni electro-deposited alloy. The experimental results, ...
Synthesis of thermoplastic poly(ester-siloxane)s in the melt and in solution / Sinteza termoplastičnih poli(estar-siloksana) u rastopu i rastvoru
(Serbian Chemical Society, 2005)
Two series of thermoplastic elastomers, based on poly(dimethylsiloxane) PDMS, as the soft segment and poly(butylene terephthalate), PBT, as the hard segment, were synthesized by catalyzed transesterification, from dimethyl ...
The kinetics of the partial dehydration of gibbsite to activated alumina in a reactor for pneumatic transport
(Serbian Chemical Society, 2001)
The dehidration kinetics of gibbsite to activated alumina was investigated at four different temperatures between 883 K and 943 K in a reactor for pneumatic transport in the dilute two phase flow regime. The first order ...
The influence of some factors on the electrical conductivity and particle size of core/shell polystyrene/polyaniline composites / Утицај неких фактора на електричну проводљивост и величину честица композита са језгром од полистирена и омотачем од полианилина
(Serbian Chemical Society, 2005)
The electrically conductive, micron-sized, core/shell polystyrene (PS)/polyaniline (PANI) composite particles were synthesized by chemical oxidative polymerization of aniline in the presence of micron-sized PS particles ...
Open-framework aluminophosphates: Synthesis, characterization and transition metal modifications / Porozni alumofosfati - sinteza, karakterizacija i modifikovanje jonima prelaznih metala
(Serbian Chemical Society, Belgrade, 2005)
This review is a brief summary of open-framework aluminophosphates and their transition metal-substituted modifications. The materials exhibit structural and compositional diversity, as well as a wide range of pore openings, ...
The STM analysis of a silver mirror surface / STM analiza površine srebrnog ogledala
(Serbian Chemical Society, 2001)
In this work, the structure of a silver mirror surface was examined by the STM technique. It was shown that the structural characteristics which enable a high degree of mirror reflection from this surface, which is very ...
