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 ...
In silico–in vitro estimation of lipophilicity and permeability association for succinimide derivatives using chromatographic anisotropic systems and parallel artificial membrane permeability assay
(Biomedical Chromatography, 2022)
Passive permeability is one of the key features that determine absorbability and one of the most studied properties in the early phases of drug development. Newly synthesized succinimide derivatives from two different ...
Beech sawdust based adsorbents for solid-phase extraction of pesticides and pharmaceuticals
(Serbian Chemical Society, 2022)
Carbonaceous solid-phase extraction (SPE) sorbent, efficient in isol-ation and enrichment of multiclass pesticides and pharmaceuticals from water, was synthesized starting from cheap waste beech sawdust and using KOH as ...
Disparate soil textures as a native medium for As(V) and Pb(II) separation from aqueous systems
(Desalination Publications, 2022)
This study investigated the use of different natural raw soil materials as low-cost adsorbents for
the removal to remove As(V) and Pb(II) from aqueous systems. It deals with the effect of different soil textures, sandy ...
Influence Of Radiation On The Stability Of Electrical Filters Characteristics As Components For Overvoltage Protection
(Vinca Inst Nuclear Sci, 2022)
The paper represents the results of testing the effect of neutron and gamma radiation of radioactive 60 Co on electrical filters. Neutron and gamma radiation was chosen because of its conductivity. The analysis of the ...
Forced Periodic Operation of Methanol Synthesis in an Isothermal Gradientless Reactor
(John Wiley and Sons Inc, 2022)
Methanol synthesis from synthesis gas with heterogeneous Cu/ZnO/Al2O3 catalysts in an isothermal gradientless reactor is described. In a theoretical study, the potential of forced periodic operation (FPO) for improving ...
Thermo-mechanical analysis of linear welding stage in friction stir welding Influence of Welding Parameters
(VINČA Institute of Nuclear Sciences, 2022)
The influence of friction stir welding parameters on thermo-mechanical behavior of the material during welding is analyzed. An aluminum alloy is considered (Al 2024 T351), and different rotating and welding speeds are ...
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 ...
To Professor Petar Pfendt, In calidum, et plurium retributivus memoriae: FTIR-ATR analysis of post stamps of the Principality of Serbia issued in 1866 and 1868 and their forgeries
(Journal of the Serbian Chemical Society, 2022)
In order to further define the potential use of FTIR-ATR spectroscopy, as a non-destructive and reliable technique, for the analysis of the characteristics of post stamps, certified originals of the Principality of Serbia ...
