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, ...
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 ...
Aminoquinolines afford resistance to cerebral malaria in susceptible mice
(Elsevier, 2020)
Objectives: Malaria treatment is impeded by increasing resistance to conventional antimalarial drugs. Here we explored the activity of ten novel benzothiophene, thiophene and benzene aminoquinolines. Methods: In vitro ...
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
microreactor intended for ...
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 ...
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 ...
The Influence of pH on Electrochemical Behavior of Nicotine- Clay based Electrodes
(Belgrade : International Institute for the Science of Sintering (IISS), 2021)
Montmorillonite based clay was acid activated. Nicotine was adsorbed on untreated
and acid activated clay from its aqueous solution at either pH=6 or pH=9.26 (unadjusted pH
solution). The XRD analysis revealed that the ...
Substrate type selection in diatom based lake water quality assessment
(EDP Sciences, 2021)
Various studies report contrasting results on the substrate-type effect on diatom community composition, but the particularly important question is whether or not it affects diatom-based assessments of water quality. We ...
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 ...
Synthesis and antibacterial activity of iron manganite (FeMnO3) particles against the environmental bacterium Bacillus subtilis
(London : Royal Society of Chemistry, 2020)
Nanocrystalline iron manganite powder was synthesized using the sol–gel combustion process, with
glycine as fuel. It was further calcined at 900 C for 8 h, resulting in the formation of a loose cubic
FeMnO3 powder with ...
