Some negative chemical properties of acid soils / Neka negativna svojstva kiselih zemljišta
(Srpsko hemijsko društvo, Beograd, 2005)
Some important chemical properties of various samples of two types of acid soil from Western Serbia (pseudogley and brown forest) are presented in this paper. Mobile Al was found in elevated and toxic quantities (10–30 ...
Mathematical modeling of cell distribution in alginate microbeads
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
Alginate is one of the mostly used hydrogels for cell entrapment aimed for applications in food industry, environmental engineering, pharmacy and biomedicine. One of the major parameters affecting cell viability and activity ...
Comparative study of the active sites in zeolites by different probe molecules / Uporedno ispitivanje aktivnih centara zeolita različitim probnim molekulima
(Srpsko hemijsko društvo, Beograd, 2005)
This review summarizes some of the recently published results concerning the acid sites in the zeolites ZSM-5 and Y studied by temperature-programmed desorption (TPD) and adsorption calorimetry using different probe molecules ...
Application of the master sintering curve theory to non-isothermal sintering of BaTiO3 ceramics
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
In this paper a practical approach to the analysis of sintering of BaTiO3 using the Master Sintering Curve concept has been presented. Non-isothermal sintering of high-purity non-doped BaTiO3 ceramics was monitored using ...
A study of the adsorption thermodynamics of n-hexane on ion-exchanged X zeolites / Termodinamika adsorpcije n-heksana na jonski izmenjenim X zeolitima
(Srpsko hemijsko društvo, Beograd, 2005)
In this work, the free energy changes and entropy changes of adsorption of n-hexane on zeolites of the MxNa87-2xX (M=Co,Ni,Zn,Cd) type were determined using their isosteric sorption heats. It was found that the exchange ...
