Diffusional processes in the biomass conversion
(Slovnaft VÚRUP, 2012)
Diffusional process with biochemical reaction was investigated. Fermentation for ethanol production with Saccharomces Cerevisia was carried out with Ca-alginate gel in the form of layer spherical beads in the anaerobic ...
The influence of different supplements on the probiotic character of fermented whey-based beverage / Uticaj različitih dodataka na probiotski karakter fermentisanog napitka na bazi surutke
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2013)
The aim of this study was the selection of appropriate supplements for the probiotic whey-based beverage production by Lactobacillus johnsonii NRRL B-2178. The analysis of the main effects and their interactions was performed ...
Morphology of Nanotubular Oxide Layer Formation on Titanium and Titanium Alloy Using Electrochemical Anodization
(Belgrade : Serbian Academy of Sciences and Arts, 2018)
Synthesis and characterization of novel semi-degradable, pH and temperature sensitive hydrogels based on 2-hydroxyethyl methacrylate and 2-hydroxyethyl acrylate
(Beograd : Srpsko hemijsko društvo = Serbian Chemical Society, 2018)
Hydrogels represent three-dimensional hydrophilic polymer networks, capable of absorbing large quantities of water1. Due to their tissue-like characteristics, hydrogels have been widely used for a variety of biomedical and ...
Seasonal variations of concentrations of low-molecular weigth organic acids in atmospheric aerosols
(Belgrade : Public Health Institute, 2019)
In addition to inorganic ions, low-molecular weight organic acids (LMWOA) form one of the major components
of atmospheric aerosols (Djordjević et al, 2012; Joksić et al, 2009). LMWOAs contribute significantly to the
presence ...
Scientific and Technical Communication
(Niš : University of Niš, 2018)
In this chapter we tried to present some recommendations
and insights, mostly based on previous experiences, how to make scientific
communication better. We tried to classify and describe various types of
scientific and ...
The influence of alkali treatment on the chemical composition, sorption and electrokinetic properties of jute woven fabrics
(Skopje : Society of chemists and technologists of Macedonia, 2018)
In this investigation, the influence of alkali treatment on the chemical composition (content of
hemicelluloses), sorption properties and surface charge of jute woven fabrics were studied. In order to
partially remove ...
Polyurethane networks based on polycaprolactone and hyperbranched polyester: Structural, thermal and mechanical investigation
(Elsevier Science Sa, Lausanne, 2019)
A series of environmentally friendly polyurethane (PU) networks based on polycaprolactone as soft segment (SS) and Boltorn (R) aliphatic hyperbranched polyester of the second pseudo generation as crosslinking agent was ...
Electrochemical and biocompatibility examinations of high-pressure torsion processed titanium and Ti-13Nb-13Zr alloy
(Wiley, Hoboken, 2018)
The purpose of this study was to estimate the electrochemical behavior and biocompatibility of ultrafine-grained (UFG) commercially pure titanium (CPTi) and Ti-13Nb-13Zr (TNZ) alloy obtained by high-pressure torsion process. ...
Titanium dioxide nanoparticles surface modified with imine as fillers for epoxy resin / Nanočestice titan-dioksida površinski modifikovane iminom kao punioci za epoksidnu smolu
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2018)
The surface of anatase TiO2 nanoparticles was modified with in situ synthesized imine, based on 3,4-dihydroxybenzaldehyde and octadecylamine. The modified TiO2 nanoparticles were investigated using FTIR and UV-Vis spectroscopy, ...
