Element Content in Volcano Ash, Soil and River Sediments of the Watershed in the Volcanic Area of South Iceland and Assessment of Their Mobility Potential
(MDPI, 2021)
In this work, we present the results of element content in river sediments and soil of the Rangárvellir river in southern Iceland as well as in the volcano ash from the Eyjafjallajökull eruption in 2010. Severe natural ...
Intermittent Chaos in the CSTR Bray–Liebhafsky Oscillator-Specific Flow Rate Dependence
(Frontiers Media S.A., 2020)
Dynamic states with intermittent oscillations consist of a chaotic mixture of large
amplitude relaxation oscillations grouped in bursts, and between them, small-amplitude
sinusoidal oscillations, or even the quiescent ...
Biotransformation of Perrottetin F by Aspergillus niger: New Bioactive Secondary Metabolites
(Türkiye : ACG Publications, 2021)
Biotransformation of bis-bibenzyl perrottetin F (1), isolated from the liverwort Lunularia cruciata by Aspergillus niger, has been investigated. New metabolites (2-4) have been isolated using reversed phase semipreparative ...
Monolithically Integrated Diffused Silicon Two-Zone Heaters for Silicon-Pyrex Glass Microreactors for Production of Nanoparticles: Heat Exchange Aspects.
(MDPI, 2020)
We present the design, simulation, fabrication and characterization of monolithically
integrated high resistivity p-type boron-di used silicon two-zone heaters in a model high temperature

Synthesis, Characterization, Catalytic Activity, and DFT Calculations of Zn(II) Hydrazone Complexes
(MDPI, 2020)
Two new Zn(II) complexes with tridentate hydrazone-based ligands (condensation products of 2-acetylthiazole) were synthesized and characterized by infrared (IR) and nuclear magnetic resonance (NMR) spectroscopy and single ...
Macroporous monoliths based оn natural mineral sources, clay аnd diatomite
(Belgrade : Association for ETRAN Society, 2020)
Macroporous silica ceramic was obtained using clay and diatomite. Boric acid as a low-cost additive in the amount of 1 wt% was used. These porous materials were obtained at low forming pressure (40-80 MPa) and lower sintering ...
Transesterification of Sunflower Oil Over Waste Chicken Eggshell-Based Catalyst in a Microreactor: An Optimization Study
(MDPI, 2021)
The statistical experimental design (DoE) and optimization (Response Surface Methodology combined with Box–Behnken design) of sunflower oil transesterification catalyzed by waste chicken eggshell-based catalyst were conducted ...
Immobilized Alcalase on Micron- and Submicron-Sized Alginate Beads as a Potential Biocatalyst for Hydrolysis of Food Proteins
(MDPI, 2021)
Enzymatic hydrolysis of food proteins is convenient method to improve their functional properties and physiological activity. Herein, the successful covalent attachment of alcalase on alginate micron and submicron beads ...
Comparative analysis of numerical computational techniques for determination of the wind turbine aerodynamic performances
(Institut za nuklearne nauke “Vinča” - Društvo termičara Srbije, 2021)
The purpose of this paper is to explore and define an adequate numerical
setting for the computation of aerodynamic performances of wind turbines of
various shapes and sizes, which offers the possibility of choosing a ...
Effect оf delamination оn physico-chemical properties оf kaolin
(International Institute for the Science of Sintering (IISS), 2021)
To provide the quality required for its use, raw kaolin must be subjected to certain processing procedures like delamination which is applied to the layered structure materials. The aim of this research is to determine the ...
