Novel artesunate–pyrimidine-based hybrids with anticancer potential against multidrug-resistant cancer cells
(Royal Society of Chemistry, 2023)
The synthesis of 17 hybrid molecules, consisting of artesunate, a derivative of naturally occurring artemisinin, and synthetic 4-aryl-2-aminopyrimidines, is described. New compounds were designed to improve the parent ...
Set of Small Molecule Polyurethane (PU) Model Substrates: Ecotoxicity Evaluation and Identification of PU Degrading Biocatalysts
(Switzerland : Multidisciplinary Digital Publishing Institute (MDPI), 2023)
Polyurethanes (PUs) are an exceedingly heterogeneous group of plastic polymers, widely used in a variety of industries from construction to medical implants. In the past decades, we have witnessed the accumulation of PU ...
Spatial–temporal assessment of hydrocarbon biodegradation mechanisms at a contaminated groundwater site in Serbia
(England: Taylor and Francis, 2022)
The characterization and cleanup of groundwater contamination in hazardous-waste sites are of significant engineering and scientific importance. This study analyzes biodegradation fingerprints in groundwater, 25 years after ...
Multiblock copolymers containing poly(butylene succinate) and poly(ε-caprolactone) blocks: Effect of block ratio and length on physical properties and biodegradability
(Springer, 2022)
In order to obtain polymers with preserved thermal properties and tunable biodegradability multiblock copolymers comprising blocks of biodegradable polyesters poly(ε-caprolactone) (PCL) and poly(butylene succinate) (PBS) ...
Heavy metal concentrations in the soil near illegal landfills in the vicinity of agricultural areas—artificial neural network approach
(Springer Nature, 2023)
Purpose To anticipate the impact of illegal landfills, development of new models should become a part of environmental risk management strategies. One of such approaches includes applications of the artificial neural network ...
Thermal analysis and phase changes of mechanochemically activated sodium carbonate
(Elsevier, 2022)
Sodium carbonate is a well-known material for being used as a good sorbent of carbon dioxide from the atmosphere, and as such has gained increasing importance in environmental protection. In order to enhance its sorption ...
Charge assisted assembly of zwitterionic pyridone hydrates
(Elsevier, 2021)
Two pyridone derivatives, bearing the pyridinium moiety (1), or dimethylpyridinium moiety (2), have been synthesized and their crystal structures have been determined. The compounds crystalize in hydrated zwitterionic forms ...
The Influences of Climatic and Lithological Factors on Weathering of Sediments in Humid Badland Areas
(Frontiers Media S.A., 2022)
Climate variables including temperature, rainfall intensity, rainfall acidity, and lithological properties are among the most important factors affecting rock weathering. However, the relative contribution of these four ...
Heat transfer to a sphere immersed in a fluidized bed of coarse particles with transition from bubbling to turbulent flow regime
(Taylor & Francis, 2023)
The present work concerns an experimental study on heat transfer in gas-solid fluidized bed of coarse (Geldart D) particles to a larger immersed sphere at high superficial velocities from 2 to 5.5 Umf. The heat transfer ...
Screening of Volatile Compounds, Traditional and Modern Phytotherapy Approaches of Selected Non-Aromatic Medicinal Plants (Lamiaceae, Lamioideae) from Rtanj Mountain, Eastern Serbia
(Basel : MDPI, 2023)
Ironwort (Sideritis montana L.), mountain germander (Teucrium montanum L.), wall germander (Teucrium chamaedrys L.), and horehound (Marrubium peregrinum L.) are species widely distributedacross Europe and are also found ...
