Crystallization support tube in a laboratory furnace
(University of Kragujevac, Faculty of Science, 2018)
Design of modular, simple to build and handle air cooler ('crystallization support tube') installed in a laboratory tube furnace is presented. The setup allows easy regulation and simultaneous crystallization tests of ...
Cavitation of refratory samples based on talc and domestic zeolite / Ispitivanje vatrostalnih uzoraka na bazi talka i domaćeg zeolita na dejstvo kavitacije
(Savez inženjera i tehničara Srbije, Beograd, 2018)
Using domestic zeolite from Igroš as row material for ceramic samples for application in condition of cavitation erosion. Samples based on talc with 15 % of zeolite, from Igroš, sintered at 1200oC were used in this ...
Non-thermal plasma as a pretreatment for extraction of herbal tea by-products / Ekstrakcija sporednih proizvoda prerade biljnih čajeva uz pretretman gasnom plazmom
(National Society of Processing and Energy in Agriculture, 2023)
Traditional extraction methods involve the use of polar solvents and/or high temperatures. Both are often energy or time-consuming and require additional purification steps. This compromises the quality of the extracts ...
Poboljšanje apsorpcionih svojstava TiO2 nanocevi pomoću CH3NH3PbBr3 perovskita kao fotosenzitivizatora / Improvement of absorption properties of TiO2 nanotubes by using CH3NH3PbBr3 perovskite as photosensitizer
(Savez inženjera i tehničara Srbije, 2022)
Organsko-neorganski perovskiti su privukli veliku pažnju istraživača zbog visoke apsorpcije u vidljivom
delu spektra i jeftine proizvodnje. Apsorbovanjem svetlosti dolazi do stvaranja para elektron-šupljina.
U cilju ...
Ispitivanje fitostimulatornog delovanja bakterijskih sojeva tokom gajenja uljanog lana i crnog kima
(Serbian Association of Plant Breedings and Seed Producers, Belgrade, 2022)
U cilju proučavanja uticaja bakterija koje stimulišu rast biljaka, a koje pripadaju rodu Strep-
tomices sp , Paenibacillus sp i Hymenibacter sp , na prinos i kvalitet semena uljanog lana i crnog
kima, kao i na morfološke ...
Production of lactic acid on liquid distillery stillage / Proizvodnja mlečne kiseline na tečnoj destilerijskoj džibri
(Nacionalno društvo za procesnu tehniku i energetiku u poljoprivredi, Novi Sad, 2011)
Bioethanol produced by fermentation of biomass is one of the most important renewable and ecologically friendly energy resources today. After bioethanol distillation a considerable amount of liquid stillage remains (1 hl ...
Characterisation of biocompatible layers of ZrO28%Y2O used in combination with other ceramics to modify the surface of implants / Karakterizacija biokompatibilnih slojeva ZrO28%Y2O3 koji se koriste u kombinaciji sa drugom keramikom za modifikaciju površine implantata
(Inženjersko društvo za koroziju, 2021)
The aim of this study was to deposit multi-functional ZrO28%Y2O3 coating layers using the plasma spray technology and then to characterise such layers. In combination with other biomedical ceramics, this coating is intended ...
Characterization of NiAl layers deposited by atmospheric plasma spray (APS) / Karakterizacija NiAl slojeva deponovanih atmosferskim plazma sprejom (APS)
(Engineering Society for Corrosion, Belgrade, Serbia, 2020)
In this paper analyzed were the mechanical properties and microstructure of the Ni30Al coating layers deposited using atmospheric plasma spray (APS). For deposition of the coating applied was a composite Ni30wt.% Al powder, ...
Numerical simulation of constraint effect on fracture initiation in welded specimens using a local damage model / Numerička simulacija uticaja veze na inicijaciju loma kod zavarenih epruveta upotrebom modela lokalnog oštećenja
(Society for Structural Integrity and Life, Institute for Material Testing, 2011)
In this paper, two micromechanical models: the Gurson-Tvergaard-Needleman (GTN) model and Complete Gurson Model (CGM) are used to predict ductile fracture initiation of two different welded specimens, SE(B) and C(T). The ...
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, ...
