The Competition for best technology innovation, organized by the Serbian Ministry of Education, Science and Technology Development, has been held since 2005. The public call for participation in the Competition is announced ...
Carbon Supported PtSn versus PtSnO2 Catalysts in Methanol Oxidation
(International Journal of Electrochemical Science, 2021)
Pt, PtSn and PtSnO2 catalysts supported on high surface area carbon synthesized by microwave assisted polyol procedure were tested for methanol oxidation. Based on TGA, EDX and XRD analysis, PtSn/C is composed of Pt and ...
Supercritical CO2 extraction of steroidal sapogenins from fenugreek (tngonella foenum-graecum l.) Seed
(Savez hemijskih inženjera, Beograd, 2020)
Supercritical CO2 extraction was applied on fenugreek (Trigonella foenum-graecum L., Fabaceae) seeds with the aim to define optimal process conditions to obtain the maximal extract yields content of steroidal sapogenins. ...
Efficient replacement of the radioactive sources in the gas-filled surge arresters construction for the insulation co-ordination at the low voltage level
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2020)
The possibility of the classical response rate engineering and the long-term deconditioning of the gas-filled surge arresters is considered in this paper. The obtained results are compared with the same results obtained ...
Ambient air particles: The use of ion chromatography and multivariate techniques in the analysis of water-soluble substances
(Journal of the Serbian Chemical Society, 2021)
Seventeen water-soluble substances (of sodium, ammonium, potas-sium, magnesium, calcium, formate, methanesulfonate, glyoxylate, chloride, nitrite, nitrate, glutarate, succinate, malate, malonate, sulfate and oxalate) in ...
Evaluation of soft tissue regenerative processes after subcutaneous implantation of silver/ poly(vinyl alcohol) and novel silver/poly(vinyl alcohol)/graphene hydrogels in an animal model
(Acta Veterinaria-Beograd, 2021)
A newly produced biomaterial is necessarily subject of standards, which are performed in vivo on animal models. For the evaluation of soft tissue regenerative possibilities after subcutaneous implantation of biomaterials ...
Efficiency of calcium hydroxide removal techniques from simulated internal root resorptions - in vitro study
(Srpski Arhiv Za Celokupno Lekarstvo, 2021)
Introduction/Objective Calcium hydroxide (CH) is the medicament of choice in endodontic treatment of internal root resorptions. The aim of the study was to compare the effectiveness of three different techniques for CH ...
Effects of waste sulfur content on properties of self-compacting concrete
(Consejo Superior Investigaciones Cientificas-Csic, Madrid, 2020)
Self-compacting concrete (SCC) contains fine mineral fillers such as limestone powder. The idea of this study was to partially replace limestone with waste sulfur since it is hydrophobic, insoluble in water and therefore ...
Thermo-responsive hydrogels based on poly(N-isopropyl- acrylamide) and hyaluronic acid cross-linked with nanoclays
(Srpsko hemijsko društvo, Beograd, 2020)
Semi-interpenetrating polymer networks (SIPN) based on thermo-responsive poly(N-isopropylacrylamide) (PNIPA) and water-soluble sodium salts of linear hyaluronic acid (Na-HA) were physically cross-linked with synthetic ...
Statistical optimization of bioethanol production from waste bread hydrolysate
(Journal of the Serbian Chemical Society, 2021)
A recent trend in sustainable bioethanol production is the use of agricultural waste or food waste as an inexpensive and the most available feedstock. Bread waste is the major food waste that could be successfully used for ...
