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 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 ...
Mechanochemical synthesis and electrical conductivity of nanocrystalline δ-Bi2O3 stabilized by HfO2 and ZrO2
(Belgrade : Serbian Chemical Society, 2009)
A powder mixture of α-Bi2O3 and HfO2, in the molar ratio 2:3, was mechanochemically treated in a planetary ball mill under air, using zirconium oxide vials and balls as the milling medium. After 50 h of milling, the ...
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 growth of ruby single crystals / Раст монокристала рубина
(Serbian Chemical Society, 2005)
Ruby (Cr:Al2O3) single crystals were grown by the Czochralski technique in an argon atmosphere. The critical crystal diameter dc = 1.0 cm and the critical rate of rotation ωc = 20 rpm were calculated by equations of the ...
Mean heat transfer coefficients during the evaporation of 1,1,1,2-tetrafluoroethane (R-134a) in a plate heat exchanger
(Serbian Chemical Society, 2007)
In this study the transfer coefficient of evaporation heat of the refrigerant 1,1,1,2-tetrafluoroethane (R-134a) in a vertical plate heat exchanger was experimentally investigated. The results are presented as the dependancy ...
The gas holdup in a multiphase reciprocating plate column filled with carboxymethylcellulose solutions / Утицај концентрације раствора и степена полимеризације карбоксиметилцелулозе на садржај гаса у реактору са вибрационом мешалицом
(Serbian Chemical Society, 2005)
Gas holdup was investigated in a gas-liquid and gas-liquid-solid reciprocating plate column (RPC) under various operation conditions. Aqueous carboxymethylcellulose (sodium salt, CMC) solutions were used as the liquid ...
The effect of particle structure on apparent density of electrolytic copper powder / Uticaj strukture čestica na nasipnu masu elektrolitički dobijenog bakarnog praha
(Serbian Chemical Society, 2001)
The quantitative microstructural analysis and the sieve analysis of copper powder as well as the scanning electron microscopy analysis of the copper powders particles were performed. It was found that the structure of the ...
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, ...
