Crystallization shelves for laboratory furnaces
(Wiley-VCH Verlag Gmbh, Weinheim, 2007)
Several designs of air coolers (modular bilateral "crystallization shelves"), installed in laboratory furnaces are presented. The setup allows easy regulation and simultaneous crystallization of several substances at ...
Wall-to-liquid mass transfer in fluidized beds and vertical transport of inert particles / Prenos mase zid-fluid u fluidizovanim slojevima i pri vertikalnom transportu inertnih čestica
(Serbian Chemical Society, Belgrade, 2007)
Mass transfer coefficients in single phase flow, liquid fluidized beds and vertical hydraulic transport of spherical inert particles were studied experimentally using 40 mm and 25.4 mm diameter columns. The mass transfer ...
Dynamic mechanical properties and in vitro bioactivity of PHBHV/HA nanocomposite
(Elsevier Sci Ltd, Oxford, 2007)
Biopolymer composite materials for potential medical applications are of current research interest. In this study, a nanocomposite based on bioresorbable polymer-poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBHV) was ...
A kinetic study of the thermal degradation of cetyltrimethylammonium bromide inside the mesoporous SBA-3 molecular sieve / Kinetičko izučavanje termičkog razlaganja cetiltrimetilamonijum−bromida unutar mezoporoznog molekulskog sita SBA-3
(Serbian Chemical Society, Belgrade, 2007)
The thermal degradation of cetyltrimethylammonium bromide (CTMAB) inside the mesoporous SBA-3 was studied under non-isothermal conditions. There are two distinct and complex kinetic processes which partly overlap, each ...
Vapor-liquid equilibria of triglycerides-methanol mixtures and their influence on the biodiesel synthesis under supercritical conditions of methanol / Ravnoteža para-tečnost za sistem trigliceridi-metanol i njen uticaj na kinetiku sinteze biodizela pod uslovima natkritičnog metanola
(Serbian Chemical Society, Belgrade, 2007)
The non-catalytic synthesis of biodiesel (fatty acids methyl esters) from triglycerides and methanol proceeds at elevated pressures above 100 bar and temperatures above 523 K. Kinetic investigations of the system revealed ...
Carrier's mobility temperature dependence in analytical model of SiC based MOSFET structure current-voltage characteristics / Temperaturna zavisnost pokretljivosti nosilaca u analitičkom modelu strujno-naponskih karakteristika MOSFET strukture izrađene na bazi SiC
(Savez inženjera i tehničara Srbije, Beograd, 2007)
In this paper temperature dependence on current-voltage characteristics of a SiC based MOSFET structure is considered. This influence is modeled by introducing temperature impact on carrier's mobility. Proposed model ...
Cyclopropyl building blocks in organic synthesis, part 143. A two-step, three-component queuing cascade leading to dihydrobenzoxepine and dihydrobenzazepine derivatives
(Wiley-VCH Verlag Gmbh, Weinheim, 2007)
A palladium-catalyzed reaction of methylenespiropentane (11) with iodobenzene (12) under typical Heck conditions [Pd(OAC)(2), PPh3, Et3N, DMF] produced a mixture of the unstable [3]dendralene 13 and allylidenecyclopropane ...
Influence of microenvironmental conditions on hybridoma cell growth inside the alginate-poly-L-lysine microcapsule
(Elsevier Sci Ltd, Oxford, 2007)
A mathematical model was formulated to describe hybridoma cell growth within the alginate-poly-L-lysine (alginate-PLL) microcapsules during air-lift bioreactor cultivation. Model development was based on experimentally ...
Adhesion of epoxy cataphoretic coatings on Zn alloys / Adhezija epoksidnih kataforetskih prevlaka na legurama cinka
(Serbian Chemical Society, Belgrade, 2007)
One of the most important factors in corrosion prevention by protective coatings is the loss of coating adhesion under environmental influence. In this work, the adhesion of epoxy cataphoretic coatings was examined on steel ...
Uticaj tranzicije na unapređenje poslovnog uspeha ekonomskih subjekata
(Društvo ekonomista Beograda, Beograd, 2007)
The privatization process and its impact on the business environment in this paper are studied. The analysis of the successful case in this paper is studied, too. It can be concluded that the privatization process can has ...
