Non-linear frequency response of non-isothermal adsorption controlled by micropore diffusion with variable diffusivity / Nelinearni frekventni odziv neizotermnog adsorpcionog sistema čija je kinetika kontrolisana difuzijom kroz mikropore sa promenljivom difuzivnošću
(Serbian Chemical Society, Belgrade, 2000)
The concept of higher order frequency response functions (FRFs) is used for the analysis of non-linear adsorption kinetics on a particle scale, for the case of non-isothermal micropore diffusion with variable diffusivity. ...
Effects of substituents on the electronic absorption spectra of 3-N-(4-substituted phenyl)-5-carboxy uracils in different solvents: Part II / Efekat supstituenata na apsorpcione spektre 3-N-(4-supstituisanih fenil)-5-karboksi uracila u različitim rastvaračima - deo II
(Serbian Chemical Society, Belgrade, 2000)
Absorption spectra of some 3-N-(4-substituted phenyl)-5-carboxy uracils, previously determined in twelve solvents, are correlated with substituent sp+ values or by dual substituent parameter correlations involving sI and ...
Immobilization/encapsulation of cells using electrostatic droplet generation - Experiments and theory
(Minerva Biotecnologica, 2000)
The mechanism of alginate droplet formation as well as experimental parameters for producing very small polymer microbeads (i,e, less then 100 microns diameter) using an electrostatic droplet generator were investigated, ...
Study of chlorination of nickel ferrite by gaseous chlorine and calcium chloride in the presence of active additives
(Wiley, Hoboken, 2000)
Thermodynamic analysis and experimental research of the chlorination of nickel ferrite (NiFe2O4) by gaseous chlorine in the presence of added C, BaS, S and NaCl in the temperature range from 300 to 900 degrees C are given ...
The structure of bright zinc coatings / Struktura sjajnih prevlaka cinka
(Serbian Chemical Society, 2000)
The structures of bright zinc coatings obtained from acid sulfate solutions in the presenceof dextrin/salicylaldehyde mixture were examined. It was shown by the STM technique that the surfaces of bright zinc coatings are ...
Detecting aniline in air in systems based on piezoelectric quartz crystal resonators modified with poly(ethylene glycol succinate) under static and dynamic conditions
(Journal of Analytical Chemistry, 2000)
The optimal conditions have been found for aniline sorption on a film of poly(ethylene glycol succinate) by the piezoelectric quartz crystal microbalance method using bulk acoustic wave sensors based on AT-cut quartz ...
Study of chlorination of nickel silicate by gaseous chlorine and calcium chloride in the presence of active additives
(Wiley, Hoboken, 2000)
The paper presents a thermodynamic analysis and experimental research on the kinetics of the chlorination of nickel silicate (2NiO x SiO2) by gaseous chlorine and calcium chloride without additives and in the presence of ...
Thermal investigation of two FePO materials prepared in the presence of 1,2-diaminoethane
(Elsevier, Amsterdam, 2000)
Two porous iron phosphates were synthesized hydrothermaly from a reaction mixture of FeCl3:H3PO4:1,2-diaminoethane:H2O in the molar ratio 1:3:5:70. The chemical formulas indicate difference only in water content; however, ...
