The significance of applying different factors for the evaluation of sediment contamination by toxic elements and estimation of the ecological risk
(Springer, 2023)
The optimized three-step sequential extraction procedure for the fractionation of micro- and macroelements, was conductedto determine fractional characteristics of PTEs (potentially toxic elements) in surface sediments of ...
On the Selectivity in the Synthesis of 3-Fluoropiperidines Using BF3-Activated Hypervalent Iodine Reagents
(American Chemical Society (ACS), 2023)
Fluorinated piperidines find wide applications, most notably in the development of novel therapies and agrochemicals. Cyclization of alkenyl N-tosylamides promoted by BF3-activated aryliodine(III) carboxylates is an ...
The macro- and microelements content in Cedrus atlantica (Endl.) Manetti ex Carrière (Pinaceae) needles as an indicator for assessing the environmental status
(Springer, 2023)
The main objective of this study was to analyze the capacity of Cedrus atlantica (Endl.) Manetti ex Carrière 1855 to accumulate macro- and microelements in order to assess the environmental status. The element concentrations ...
Removal of Ni2+ ions from Contaminated Water by New Exopolysaccharide Extracted from K. oxytoca J7 as Biosorbent
(Springer, 2023)
Nowadays, exopolysaccharides (EPS) produced from bacterial cells are manufactured for their use in different industries in the world, mainly in the food, pharmaceutical, and wastewater industries. The characteristics of ...
The need for unique international legal protection of pond habitats
(Wiley, 2023)
Ponds, the most numerous freshwater habitats globally, are becoming increasingly recognized as being important for rare, endemic and endangered species, owing to the high levels of biodiversity they support and their role ...
Ultra-sensitive graphene membranes for microphone applications
(Royal Society of Chemistry, 2023)
Microphones exploit the motion of suspended membranes to detect sound waves. Since the microphone performance can be improved by reducing the thickness and mass of its sensing membrane, graphene-based microphones are ...
Exploring the supramolecular profile of 5-phenylhydantoins
(Royal Society of Chemistry, 2023)
The present study describes representative examples of supramolecular arrangement of 5-phenylhydantoins achieved through various N–H⋯O hydrogen-bonding patterns. Four derivatives, 5-ethyl-5-(4-methylphenyl)hydantoin (1) ...
Kinetics and optimization of biodiesel production from rapeseed oil over calcined waste filter cake from sugar beet processing plant
(Elsevier, 2023)
A low-cost, highly active CaO-based catalyst was prepared from waste filter cake (WFC) from a sugar beet processing factory by calcination in air at 900 °C for 2 h, referred to as the calcined filter cake (CFC). It was ...
Carbonization of MOF-5/Polyaniline Composites to N,O-Doped Carbon/ZnO/ZnS and N,O-Doped Carbon/ZnO Composites with High Specific Capacitance, Specific Surface Area and Electrical Conductivity
(Switzerland : Multidisciplinary Digital Publishing Institute (MDPI), 2023)
Composites of carbons with metal oxides and metal sulfides have attracted a lot of interest
as materials for energy conversion and storage applications. Herein, we report on novel N,O-doped
carbon/ZnO/ZnS and N,O-doped ...
Metabolomics as a Potential Chemotaxonomical Tool: Application on the Selected Euphorbia Species Growing Wild in Serbia
(Switzerland : Multidisciplinary Digital Publishing Institute (MDPI), 2023)
Chemotaxonomy presents various challenges that need to be overcome in order to obtain valid and reliable results. Individual genetic and environmental variations can give a false picture and lead to wrong conclusions. ...
