Magnetic and Geochemical Properties of Zagreb City Area Soils
(MDPI, 2023)
This study was performed to derive the first insight into the distribution of low-field volume magnetic susceptibility (MS) throughout Zagreb city, based on in situ field measurements. The most interesting locations were ...
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 ...
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 ...
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 ...
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 ...
Etching of Uncompensated Convex Corners with Sides along <n10> and <100> in 25 wt% TMAH at 80 °C
(MDPI, 2020)
This paper presents etching of convex corners with sides along <n10> and <100> crystallographic directions in a 25 wt% tetramethylammonium hydroxide (TMAH) water solution at 80 °C. We analyzed parallelograms as the mask ...
Newly Synthesized Fluorinated Cinnamylpiperazines Possessing Low In Vitro MAO-B Binding
(MDPI, 2020)
Herein, we report on the synthesis and pharmacological evaluation of ten novel fluorinated cinnamylpiperazines as potential monoamine oxidase B (MAO-B) ligands. The designed derivatives consist of either cinnamyl or ...
Geochemical Fractionation and Risk Assessment of Potentially Toxic Elements in Sediments from Kupa River, Croatia
(MDPI, 2020)
This study investigated the quality of Kupa River sediment using sequential extraction,
ecological risk, and contamination indexes (Risk assessment code, Index of geoaccumulation,
Enrichment factor, Ecological risk factor, ...
