Dispersive liquid–liquid microextraction and Monte Carlo simulation of margin of safety for octocrylene, EHMC, 2ES, and homosalate in sunscreens
(John Wiley and Sons Ltd., 2023)
Dispersive liquid–liquid microextraction (DLLME) using a floating organic drop has been optimized and used for the sample preparation of four commonly used ultraviolet filter (UVF) substances in sunscreens. Plackett–Burman ...
Overpotential controls the morphology of electrolytically produced copper dendritic forms / Пренапетост контролише морфологију електролитички произведених дендритичних форми бакра
(Belgrade : Serbian Chemical Society, 2019)
The morphologies of copper dendritic forms obtained in both potentiostatic and galvanostatic regimes of electrolysis with various amounts of the electricity were analyzed by the scanning electron microscopy (SEM) technique. ...
AERMOD air dispersion modeling and health risks of gas and oil fueled heating plant emissions
(VINČA Institute of Nuclear Sciences, 2023)
A significant part of the population in Serbia relies on central heating systems during
the winter months, with around fifty heating plants in operation across the country.
Common fuels used in these plants primarily ...
An inverse gas chromatography study of the adsorption of organics on zeolite and zeolite/iron oxyhydroxide composite at the infinite and finite surface coverage / Примена инверзне гасне хроматографије при нултој и коначној прекривености за испитивање адсорпције органских мoлекула на зеолиту и композиту зеолита и гвожђе-оксихидроксида
(Serbian Chemical Society, 2024)
The surfaces of natural (NZ) and zeolite/iron oxyhydroxide composite (ZFe) samples were analysed by means of inverse gas chromatography (IGC) using the adsorption data of organic non-polar and polar probes, in the infinite ...
Air Cooler for Crystal Growth in a Laboratory Tube Furnace
(Pleiades Publishing, 2022)
A new air cooler design (“specific two-level crystallization incubator”) with a specific arrangement of laboratory vessels by levels and double-branch air conductors at the ends and a series of movable cold thresholds ...
Mechanistic insights into the simultaneous visible-light induced photodegradation of organic pollutants by g-C3N4/titanate heterojunction
(Springer Science and Business Media B.V., 2023)
The visible-light-active heterojunctions based on TiO2 were extensively investigated due to their wide range of energy and environment applications. In this study, g-C3N4/titanate heterojunction photocatalyst was successfully ...
Impact of leaching procedure on heavy metals removal from coal fly ash / Uticaj metode izluživanja na uklanjanje teških metala iz letećeg pepela
(Savez hemijskih inženjera Srbije, 2024)
In this work, removal of heavy metals (Cr, Mn, Co, Ni, Cu, Zn, As, Cd, and Pb) from fly ash has been studied using acid leaching and wet oxidation methods. In parallel, microwave-assisted acid digestion was applied for ...
Multi-walled carbon nanotubes as lipase carriers for organic synthesis: current trends and recent update / Višeslojne ugljenične nanocevi kao nosač lipaze za organsku sintezu: pregled najnovijih trendova
(Savez hemijskih inženjera Srbije, 2024)
Lipase-catalyzed organic reactions have been widely practiced in the past three decades. Especially interesting are insoluble/immobilized forms due to providing a possibility of facile use and recyclability, thus reducing ...
Ultrasound-assisted extraction of essential and toxic elements from pepper in different ripening stages using Box–Behnken design
(John Wiley and Sons Inc., 2022)
The influence of extraction parameters on the ultrasonically assisted extraction (UAE) of K, Na, Ca, Mg, Zn, Cu, Fe, Mn, Cr, Se, Mo, Li, Al, B, Pb, Hg, Cd, As, and Ni was studied to determine the conditions when a minimum ...
Marangoni effect and cell spreading
(Springer Science and Business Media Deutschland GmbH, 2022)
Cells are very sensitive to the shear stress (SS). However, undesirable SS is generated during physiological process such as collective cell migration (CCM) and influences the biological processes such as morphogenesis, ...
