Valorization of fly ash from a thermal power plant for producing high-performance self-compacting concrete
(International Institute for the Science of Sintering, Beograd, 2020)
This study analyzes the feasibility of valorizing industrial by-product, fly ash from a
thermal power plant as a partial replacement of mineral filler-limestone for the production of
self-compacting concrete (SCC). Three ...
Effects of waste sulfur content on properties of self-compacting concrete
(Consejo Superior de Investigaciones Cientificas - CSIC, 2020)
Self-compacting concrete (SCC) contains fine mineral fillers such as limestone powder. The idea of this study was to partially replace limestone with waste sulfur since it is hydrophobic, insoluble in water and therefore ...
Application of Ni(II)-alumina Composites for Electrocatalytic Reduction of 4-nitrophenol
(International Institute for the Science of Sintering, Belgrade, 2020)
Nickel-alumina composites with various content of nickel were synthetized by sol-gel method. The characterization of samples was performed by diffuse reflectance spectroscopy and electrochemical impedance spectroscopy using ...
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 ...
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 ...
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, ...
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 ...
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 ...
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 ...
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 ...
