Catalytic activity of SnO2- and SO4 /SnO2-containing clinoptilolite in the esterification of levulinic acid
(Elsevier B.V., 2019)
Catalysts based on natural zeolite - clinoptilolite loaded with either SnO2 (TOHCLI) or sulfated SnO2 (STOHCLI) were prepared and tested in the esterification of levulinic acid (LA) with octanol or ethanol. The Sn content ...
Batch and column adsorption of cations, oxyanions and dyes on a magnetite modified cellulose-based membrane
(Springer, Dordrecht, 2020)
An optimized method is presented to make magnetite (MG) modified cellulose membrane (Cell-MG) from 3-aminopropyltriethoxysilane and diethylenetriaminepentaacetic acid dianhydride functionalized waste cell fibers; (Cell-NH(2)and ...
On the Stark broadening of the Re II spectral lines
(Elsevier Ltd., 2023)
Stark broadening parameters - full widths at half maximum (FWHM) and shifts for 11 Re II lines have been calculated. The plasma parameters used were electron density of 1017 cm−3 and temperature from 5 000 K to 80 000 K. ...

(Wiley-VCH Verlag Gmbh, Weinheim, 2020)
The strategy of combining polymers of natural and synthetic origin with inorganic components to use their unique synergistic effect for the development of the novel, sophisticated, and efficient 3D polymeric biomaterials, ...
Application of quality function deployment on shelf-life analysis of Agaricus bisporus Portobello
(Elsevier Science Bv, Amsterdam, 2017)
The aim of this study was to analyze application of quality function deployment on examining the shelf life of Agaricus bisporus Portobello packed in modified atmosphere packaging stored for 22 d at 4 degrees C. Mushrooms ...
Structurally and surface-modified alumina particles as a reinforcement in polyester-based composites with an improved toughness
(Springer, New York, 2020)
Commercial gamma - Al2O3 particles, Al2O3 n, and synthesized Al2O3 doped with iron oxide (Al2O3 Fe) were used as reinforcements to enhance the toughness of an unsaturated polyester resin (UPR). Alumina modification with ...
HSLA Steel - Simulation of Fatigue
(International Conference on New Technologies, Development and Application, NT 2020, 2020)
In present paper, based on the results of the experimental study of the behaviour of the samples made of a HSLA steel, in the form of round smooth specimens (RSS) under LCF conditions (with controlled and completely ...
A novel chitosan/tripolyphosphate/L-lysine conjugates for latent fingerprints detection and enhancement
(Journal of Forensic Sciences, 2020)
Most chemical and physical methods employed in visualizing latent marks have shown detrimental effects on human health and, therefore, some research groups have directed their attention to the utilization of various ...
