Elemental composition, heat capacity from 2 to 300 K and derived thermodynamic functions of 5 microorganism species
(Elsevier, 2021)
Detailed elemental analysis and low-temperature calorimetric measurement results are reported for the first time for Gram-positive bacteria, Gram-negative bacteria and mold fungi. Microorganism unit carbon formulas (empirical ...
Estrone derived steroidal diepoxide: Biologically active compound and precursor of a stable steroidal A,B-spiro system
(Elsevier Science Inc, New York, 2009)
A simple approach to a stable steroidal estrone derived A,B-spiro system is reported. Treatment of estrone derived A-ring diepoxyalcohol with the Ac2O-TMSOTf system at the ambient temperature led to acetylation, while at ...
Mixed steroidal tetraoxanes induce apoptotic cell death in tumor cells
(Investigational New Drugs, 2009)
In this study we investigated the antiproliferative activity of six mixed steroidal tetraoxanes against various tumor cell lines, the toxicity against normal peripheral blood mononuclear cells (PBMC), and the mode of HeLa ...
Electrochemical lithiation/delithiation kinetics and capacity of phosphate tungsten bronze and its chemically pre-lithiated derivatives in aqueous solutions
(Springer, 2016)
Monophosphate bronze (PW8O26, WPB) was synthesized by low-temperature (650 °C) heating of 12-tungstophosphoric acid (WPA). Its lithiated derivative with a low lithium content (Li3-WPB) was synthesized by heating lithium ...
Environmental impact of industrial and agricultural activities to the trace element content in soil of Srem (Serbia)
(Springer, 2019)
This study reports the contents and sources of Cu, Hg, Cr, Ni, Co, Zn, Pb, Cd, As, and B pollution in soil samples from Srem in the province of Vojvodina (Republic of Serbia). They are collected in the vicinity of local ...
The influence of m-aminobenzoic acid on electrochemical synthesis and behavior of poly(aniline-co-(m-aminobenzoic acid)
(Springer, Dordrecht, 2017)
Poly(aniline-co-(m-aminobenzoic acid)) was synthesized electrochemically at graphite electrode under galvanostatic conditions. Aqueous electrolyte for synthesis was consisted of HCl and different amount of aniline and ...
Influence of a Low Content of PEO Segment on the Thermal, Surface and Morphological Properties of Triblock and Diblock PCL Copolymers
(Springer, Dordrecht, 2016)
Two series, one of triblock (PCL/PEO/PCL) and the other of diblock (PCL/PEO) copolymers were prepared by ring-opening polymerization of epsilon-caprolactone catalized with tin(II) octoate and by using dihydroxy or monohydroxy ...
Treatment of Waste Copper Electrolytes Using Insoluble and Soluble Anodes
(Esg, Belgrade, 2013)
The use of copper anodes with non standard content of impurities for the treatment of waste, sulphur acid solutions that came as a result of the industrial process of electrolytic copper refining was investigated. Those ...
Preparation and Properties of Short Oil Alkyd Resin/TiO2 Nanocomposites Based on Surface Modified TiO2 Nanoparticles
(Hoboken : Wiley, 2018)
Alkyd resin/TiO2 nanocomposites (NC) were prepared from short oil alkyd resin and TiO2 nanoparticles (NPs) surface modified with in situ formed imine ligand, based on 3,4-dihydroxybenzaldehyde and oleylamine, or with three ...
Production of raw-starch-digesting alpha-amylase isoform from Bacillus sp under solid-state fermentation and biochemical characterization
(Springer, New York, 2014)
alpha-Amylase production by solid-state fermentation of different Bacillus sp. was studied previously on different fermentation media. However, no study has been reported on the influence of selected media on expression ...
