Drying of suspension and pastes in fluidized bed of inert particles / Sušenje suspenzija i pasta u fluidizovanom sloju inertnog materijala
(Serbian Chemical Society, 2000)
A fluid bed dryer with inert particles was used for the drying of suspensions and pastes. The effects of the operating conditions on the dryer throughput and on the product quality were investigated. Experiments were ...
Synthesis and pharmacological evaluation of several N-(2-nitrophenyl) piperazine derivatives / Sinteza i farmakološko ispitivanje novih derivata N-(2-nitrofenil) piperazina
(Serbian Chemical Society, 2007)
Six newly synthesized heterocyclic (2-nitrophenyl)piperazines, with a specific structure of the heteroaryl group, whichmimics the catechol moiety of dopamine (benzimidazoles and substituted benzimidazoles), were evaluated ...
Evaluation of saturated and aromatic hydrocarbons oil-oil maturity correlation parameters (SE Pannonian Basin, Serbia) / Евалуација матурационих параметара заснованих на засићеним и ароматичним угљоводоницима у корелацији нафта-нафта (југоисточни део панонског басена , Србија)
(Belgrade : Serbian Chemical Society, 2007)
Twenty three crude oils from the Serbian part of the Pannonian Basin (14 from the Vojvodina Province and 9 from the Drmno Depression) were investigated, aimed at an evaluation of oil-oil maturity correlation parameters ...
Application of reactive siloxane prepolymers for the synthesis of thermoplastic poly(ester-siloxane)s and poly(ester-ether-siloxane)s / Primena reaktivnih siloksanskih pretpolimera za sintezu poli(ester-siloksana) i poli(ester-etar-siloksana)
(Belgrade : Serbian Chemical Society, 2007)
Thermoplastic poly(ester-siloxane)s (TPES) and poly(ester-ether-siloxane)s, (TPEES), based on poly(butylene terephthalate) (PBT) as the hard segment and different siloxane-prepolymers as the soft segments, were prepared. ...
Non-contact measurement of thickness uniformity of chemically etched Si membranes by fiber-optic low-coherence interferometry
(IntechOpen, 2008)
We presented here one contact-less optical technique based on low-coherence interferometry for measurement of thickness and uniformity of Si membranes. We performed a single-mode fiber-optic sensing configuration that is ...
Fabrication of Sio2-based microcantilevers by anisotropic chemical etching of (100) single crystal Si / Izrada mikrogredica od SiO2 anizotropnim hemijskim nagrizanjem na monokristalnom silicijumu (100) orijentacije
(Serbian Chemical Society, 2007)
The undercutting process of thermal SiO2 microcantilevers with different orientations on (100) Si wafer was studied. The silicon substrate was removed by anisotropic chemical etching with a 25 wt. % aqueous solution of ...
Preparation and modification of itaconic anhydride-methyl methacrylate copolymers / Синтеза и модификација кополимера анхидрида итаконске киселине и метил-метакрилата
(Belgrade : Serbian Chemical Society, 2007)
The free radical copolymerisation of itaconic anhydride and methyl methacrylate in solution was studied at 60°C. The copolymer composition was determined by 1H-NMR spectroscopy and the obtained monomer reactivity ratios ...
Do altered activities of superoxide dismutases and the level of NF-κB modulate the effects of gamma radiation in HeLaS3 cells?
(Serbian Chemical Society, 2007)
Most experimental models, including cell culture studies, have demonstrated that over-expression of manganese superoxide dismutase (MnSOD) in cells bearing a carcinoma phenotype has anti-proliferative and tumour suppression ...
New method for monitoring of the oxygen reduction process in aqueous solutions / Nova metoda za monitoring procesa redukcije kiseonika u vodenim rastvorima
(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2009)
Composite electrode material based on NaX zeolite and silver dispersed both inside zeolite cavities and between the zeolite crystals, in nitrogen purged 0.1M NaOH solution, yielded the cyclic voltammograms corresponding ...
