Comparative morphological and crystallographic analysis of copper powders obtained under different electrolysis conditions
(Elsevier, 2019)
Production of copper powders by the potentiostatic electrolysis under different hydrogen evolution conditions was investigated. Copper powders were characterized by the scanning electron microscope (SEM), X-ray diffraction ...
Brachybacterium sp CH-KOV3 isolated from an oil-polluted environment-a new producer of levan
(Elsevier, 2017)
Various microorganisms isolated from polluted environments, such as Pseudomonas sp. and Micrococcus sp. can synthesize exopolysaccharides (EPSs) which are natural, non-toxic and biodegradable polymers. EPSs play a key role ...
Study of potential harmful elements (arsenic, mercury and selenium) in surface sediments from Serbian rivers and artificial lakes
(Elsevier, 2017)
This investigation examines surface sediment samples from rivers and artificial lakes (Serbia) to quantify levels of potentially harmful elements (As, Hg, and Se) and several ancillary elements (Al, Fe, Mn, Ca, Mg, C, H, ...
Ranking and similarity of conventional, microwave and ultrasound element sequential extraction methods
(Oxford : Pergamon-Elsevier Science Ltd, 2018)
This study aims to compare three extraction techniques of four sequential element extraction steps from soil and sediment samples that were taken from the location of the Pancevo petrochemical industry (Serbia). Elements ...
Low-friction, wear-resistant, and electrically homogeneous multilayer graphene grown by chemical vapor deposition on molybdenum
(Elsevier, 2020)
Chemical vapour deposition (CVD) is a promising method for producing large-scale graphene (Gr). Nevertheless, microscopic inhomogeneity of Gr grown on traditional metal substrates such as copper or nickel results in a ...
Visible light absorption of surface modified TiO2 powders with bidentate benzene derivatives
(Elsevier, 2015)
TiO2 powders with different specific surface area were prepared using reproducible, sol gel synthetic route and their ability to form hybrids with catechol and 5-amino salicylic acid was compared with the commercially ...
Persistent organic pollutants (POPs) in sediments from river and artificial lakes in Serbia
(Elsevier, 2017)
In an attempt to evaluate the toxicological condition of the most important river and artificial lakes in Serbia, 52 grab-samples were collected from different locations. Sediment samples were analyzed for PCBs (PCB 28, ...
Anti-human albumin monoclonal antibody immobilized on EDC-NHS functionalized carboxylic graphene/AuNPs composite as promising electrochemical HSA immunosensor
(Elsevier, 2020)
Diagnosis and treatment of some important diseased and metabolic disorders is based on successful detection of albumin. In this work, we aim to develop a simple immunosensor for the detection of human serum albumin in ...
Chemical composition, cytotoxic and antioxidative activities of ethanolic extracts of propolis on HCT-116 cell line
(Wiley, Hoboken, 2013)
BACKGROUND Propolis is a complex resinous sticky substance that honeybees collect from buds and exudates of various plants. Owing to its versatile biological and pharmacological activities, propolis is widely used in ...
Microstructure and biopharmaceutical performances of curcumin-loaded low-energy nanoemulsions containing eucalyptol and pinene: Terpenes’ role overcome penetration enhancement effect?
(Elsevier, 2020)
The objective of this work was to develop low-energy nanoemulsions for enhanced dermal delivery of curcumin, using monoterpene compounds eucalyptol (EUC) and pinene (PIN) as chemical penetration enhancers. Spontaneous ...
