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 ...
Global market trends of tantalum and recycling methods from Waste Tantalum Capacitors: A review
(Sustainable Materials and Technologies, 2021)
The rapid digitalization of the world, technological up-gradation, and shorten life cycle of electronic gadgets leading to the generation of an enormous amount of waste tantalum capacitors (WTCs) rich in tantalum every ...
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. ...
Tetragonal CoMn2O4 nanocrystals on electrospun carbon fibers as high-performance battery-type supercapacitor electrode materials
(Royal Society of Chemistry, 2021)
We herein report a simple two-step procedure for fabricating tetragonal CoMn2O4 spinel nanocrystals on carbon fibers. The battery-type behavior of these composite fibers arises from the redox activity of CoMn2O4 in an ...
Bifunctional catalytic activity of Zn1-xFexO toward the OER/ORR: seeking an optimal stoichiometry
(Royal Soc Chemistry, Cambridge, 2020)
Eco-friendly and rapid microwave processing of a precipitate was used to produce Fe-doped zinc oxide (Zn1-xFexO,x= 0, 0.05, 0.1, 0.15 and 0.20; ZnO:Fe) nanoparticles, which were tested as catalysts toward the oxygen reduction ...
Utilization of gamma and e-beam irradiation in the treatment of waste sludge from a drinking water treatment plant
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
An increasing production of drinking water and a significant amount of waste in the form of treated sludge can lead to a serious environmental problem. The high organic content in the sludge, together with the high summer ...
The effect of temperature on pollen germination and pollen tube growth of quince cultivars
(IV Balkan Symposium on Fruit Growing, 2020)
The effect of three different temperatures (8, 16 and 24 degrees C) on pollen germination and pollen tube growth in vitro in eight quince cultivars ('Leskovacka', Vranjska', 'Morava', 'Pazardzijska', 'Hemus', 'Asenica', ...
Hydrothermal carbonization of spent mushroom substrate: Physicochemical characterization, combustion behavior, kinetic and thermodynamic study
(Journal of Analytical and Applied Pyrolysis, 2021)
Hydrothermal carbonization (HTC) was employed for the conversion of the spent mushroom substrate (SMS) into a carbonaceous hydrochar. The effect of operating temperature (180, 200, 220, 240, and 260 ?C) on the physicochemical, ...
Optimization of Methanol Synthesis under Forced Periodic Operation
(Processes, 2021)
Traditionally, methanol is produced in large amounts from synthesis gas with heterogeneous Cu/ZnO/Al2O3 catalysts under steady state conditions. In this paper, the potential of alternative forced periodic operation modes ...
Amides as a model system of low molar mass algal organic matter. Influence on the adsorption of p-nitrophenol on activated carbon
(Elsevier, Amsterdam, 2020)
In this study, the adsorption equilibrium and diffusivity parameters of p-nitrophenol were estimated for water containing different concentrations of secondary amides. Commercial powdered activated carbon was used as an ...
