Electrochemical and structural properties of Ni(II)-alumina composites as an annealing temperature function
(International Institute for the Science of Sintering, Beograd, 2019)
Alumina powders, pure and doped with nickel, were synthetized by sol-gel method and calcined at 500, 900 and 1100°C in order to obtain mesoporous structures with a high specific surface area, well adapTab. to catalytic ...
Hydrophilic Interaction Liquid Chromatography for the Analysis of Pharmaceutical Formulations
(Bentham Science Publishers, 2024)
For a long time, Reversed-Phase Liquid Chromatography (RPLC) was the most dominant
technique for the analysis of pharmaceutical compounds, but with poor efficiency in the separation of
small polar molecules. From the ...
Oxidized humic acids from the soil of heat power plant / Oksidovane huminske kiseline iz toplane
(Serbia : Serbian Chemical Society, 2020)
Humic acids isolated from the soil of a heat power plant (HA-E) contaminated with oil were analyzed by Fourier transform infrared spectroscopy (FTIR). In comparison with a humic acids standard (HA-S), a lack of an intense ...
Flavonoids of the Heartwood of Cotinus coggygria Scop. Showing Protective Effect on Human Lymphocyte DNA
(SAGE Publications, 2021)
In continuation of our study on Cotinus coggygria from Serbia, 10 known flavonoids (1-10) were isolated from the methylene chloride/ methanol extract of the heartwood. They were tested for in vitro protective effect against ...
Modeling the biodiesel production using the wheat straw ash as a catalyst / Pepeo pšenične slame kao katalizator u proizvodnji biodizela
(Belgrade : Association of the Chemical Engineers of Serbia, 2021)
Wheat straw ash (WSA) was investigated as a new catalyst in biodiesel production from sunflower oil. The catalyst was characterized by temperature-programmed decomposition, X-ray powder diffraction, Hg porosimetry, N2 ...
Organic-geochemical characteristics of the mud from the Techirghiol Lake, Romania
(Parlar Scientific Publications, 2021)
The Techirghiol Lake, located on the Romanian coast of the Black Sea, is a hypersaline lake. In this environment, a unique ecosystem in Europe has developed with the specific capacity of producing mud by the decomposition ...
Optimization of injected radiotracer volume for flow rate measurement in closed conduits / Optimizacija zapremine radioaktivnog obeleživača pri merenju zapreminskog protoka u zatvorenim cevovodima
(Belgrade : Association of the Chemical Engineers of Serbia, 2020)
In chemical processes it is essential that the flow in the process is accurately defined. Fluid velocity measurements are important for fluid flow quality performance in flow systems. This study focuses on determination ...
Expression, purification and characterization of cellobiose dehydrogenase mutants from Phanerochaete chrysosporium in Pichia pastoris KM71H strain / Ekspresija, prečišćavanje i karakterizacija mutanata celobioza - dehidrogenaze iz Phanerochaete chrysosporium u Pichia pastoris KM71H soju
(Belgrade : Serbian Chemical Society, 2020)
Production of soluble cellobiose dehydrogenase (CDH) mutant proteins previously evolved on the surface of S. cerevisiae yeast cells was established for use in biosensors and biofuel cells. For this purpose, mutant cdh genes ...
Optimization of the active component grinding process and hydrophobization of the obtained powder fire extinguisher / Optimizacija mlevenja aktivne komponente i hidrofobizacija dobijenog sredstva za gašenje požara]
(Beograd : Savez hemijskih inženjera, 2021)
This work presents a grinding process of monoammonium phosphate (MAP) as an active component in a powder fire extinguisher (PFE). The aim was to determine the grinding time for reaching the optimal particle size of MAP ...
