Synthesis and preliminary screening for the biological activity of some steroidal Δ4-unsaturated semicarbazone derivatives
(Elsevier, 2019)
Eleven new steroidal mono- and bis(semicarbazones) 2a–e, 4d and 3a–e have been prepared starting from various 3-oxo-α,β-unsaturated steroids. Mono-semicarbazones 2a–e were further subjected to ethyl chloroacetate in boiling ...
Thin-film four-resistor temperature sensor for measurements in air
(IOP Publishing, 2019)
A temperature sensor based on four thin-film resistors is presented. Four resistors are made in the form of thin metal layer meanders on the surface of a silicon chip. Two resistors are covered with a layer of 2.3 µm thick ...

Furanocoumarin Content, Antioxidant Activity, and Inhibitory Potential of Heracleum verticillatum, Heracleum sibiricum, Heracleum angustisectum, and Heracleum ternatum Extracts against Enzymes Involved in Alzheimer’s Disease and Type II Diabetes
(Willey, 2019)
Hexane extracts of Heracleum verticillatum, H. sibiricum, H. angustisectum, and H. ternatum were studied for their furanocoumarin content antioxidant potential and acetylcholinesterase and α-amylase inhibitory activities. ...
Geochemical Fractionation and Assessment of Probabilistic Ecological Risk of Potential Toxic Elements in Sediments Using Monte Carlo Simulations
(MDPI, 2019)
The need for further research into potentially toxic elements in Serbian rivers led to an
investigation of distributions, sources, and ecological risks in a sample base of sediments from
15 rivers. The analyses were ...
Grape Seed Polyphenols and Fatty Acids of Autochthonous Prokupac Vine Variety from Serbia

Grape pomace (grape skin, seeds, and stems) represents a valuable source of bioactive compounds, thus the interest in making use of these wine waste products is increasing. Prokupac is an autochthonous Serbian variety of ...
Superior cellulolytic activity of Trichoderma guizhouense on raw wheat straw
(Springer Science and Business Media LLC, 2019)
Lignocellulosic plant biomass is the world’s most abundant carbon source and has consequently attracted attention as a renewable resource for production of biofuels and commodity chemicals that could replace fossil resources. ...
Investigation of ZnFe2O4 spinel ferrite nanocrystalline screen‐printed thick films for application in humidity sensing
(John Wiley & Sons, Inc., 2019)
Zinc ferrite nanocrystalline powder was obtained by solid state synthesis of starting zinc oxide and hematite nanopowders. Field emission scanning electron microscopy (FESEM and transmission electron microscopy (TEM), X‐ray ...
