Improved water–gas shift performance of Au/NiAl LDHs nanostructured catalysts via CeO2 addition
(MDPI, 2021)
Supported gold on co-precipitated nanosized NiAl layered double hydroxides (LDHs) was studied as an effective catalyst for medium-temperature water–gas shift (WGS) reaction, an industrial catalytic process traditionally ...
Early-Middle Miocene paleoenvironmental and paleoclimate changes in the Toplica Basin (Serbia) inferred from plant biomarkers, biochemical and elemental geochemical proxies
(Central Library of the Slovak Academy of Sciences, 2021)
The study investigates the influence of alluvial-lacustrine processes and paleoclimate variations on the distribution of terpenoids and unsubstituted Polycyclic Aromatic Hydrocarbons (PAHs). The XRF, ICP-MS, Rock-Eval, and ...
Effectiveness of Nature-Based Solutions in Mitigating Flood Hazard in a Mediterranean Peri-Urban Catchment
(MDPI, 2020)
Urbanization alters natural hydrological processes and enhances runoff, which affects flood hazard. Interest in nature-based solutions (NBS) for sustainable mitigation and adaptation to urban floods is growing, but the ...
DNA protective activity of triterpenoids isolated from medicinal mushroom Fomitopsis betulina / DNK protektivna aktivnost triterpena izolovanih iz medicinske gljive Fomitopsis betulina
(Belgrade : Serbian Chemical Society, 2021)
Eleven 31-methylenlanostane triterpenoids, i.e., seven 21- and four 26-oic acids, as well as a lupane triterpenoid betulin, isolated from the fruiting bodies of the mushroom Fomitopsis betulina, were tested for in vitro ...
A new species of Leonhardia Reitter, 1901 (Coleoptera, Leiodidae, Leptodirini) from Bosnia and Herzegovina, with a key to species of the genus
(Pensoft Publishers, 2021)
A new leptodirine leiodid beetle species belonging to the genus Leonhardia Reitter, 1901, L. solaki sp. nov., from a pit in Bosnia and Herzegovina (western Balkan Peninsula) is described and diagnosed. Important morphological ...
Laser techniques and couplings with other techniques in contemporary problem solving in theory and practice
(Academy of Sciences and Arts of the Republic of Srpska / Академија наука и умјетности Републике Српске, 2020)
Problems of today, pro et contra of new breakthroughs in high frequencies and pandemics, seem to have called for even more complex correlations and couplings of the fields: science, empiria (practice), mass-media in mastering ...
Magnetic anisotropy in pentagonal bipyramidal complexes of first-row transition metal ions / Magnetna anizotropija u pentagonalno bipiramidalnim kompleksima prve serije prelaznih metala
(Belgrade : Serbian Chemical Society, 2022)
We present a validation study that aims to accurately describe magnetic anisotropy using the density functional theory (DFT) approach. We have examined 26 seven-coordinate high-spin first-row transition metal complexes ...
Forced periodic reactor operation: Analysis of process and forcing parameters exploiting the nonlinear frequency response method
(WILEY-VCH, 2020)
Continuous chemical reactors are mostly operated under steady-state conditions. However, theoretical studies reveal that forced periodic operation (FPO) can lead to better performance. To predict and optimize FPO, the ...
Al-Pd alloy formation by aluminium underpotential deposition onto palladium from chloroaluminate melt
(Belgrade : ESG, 2021)
The possibility of electrochemical underpotential deposition of aluminium onto palladium from equimolar AlCl3+NaCl melts at temperatures between 200 ° and 300 °C was investigated. Electrochemical techniques used were cyclic ...
Influence of Parameters and Regimes of the Electrodeposition on Morphology and Structure of Tin Dendrites / Uticaj parametra i režima elektrohemijskog taloženja na morfologiju i strukturu dendrita kalaja
(Beograd : Serbian Society of Corrosion and Materials Protection UISKOZAM / Udruženje inženjera Srbije za koroziju i zaštitu materijala UISKOZAM, 2022)
Tin dendrites were synthesized via electrochemical route from the alkaline electrolyte applying both
potentiostatic and galvanostatic regimes of the electrodeposition. Various both cathodic potentials
and amounts of ...
