Mechanical properties and microstructure of molybdenum coating layers deposited vacuum plasma spray process / Mehanička svojstva i mikrostruktura slojeva prevlake molibdena deponovane vakuum plazma sprej procesom
(Engineering Society for Corrosion, Belgrade, Serbia, 2019)
Molybdenum coatings due to their excellent wear resistant properties and sliding characteristics under dry friction conditions are often used in applications to resist friction and dry sliding. Since molybdenum metal is ...
Numerical simulation of the plunge stage in friction stir welding / Numerička simulacija faze uranjanja kod zavarivanja trenjem mešanjem
(Society for Structural Integrity and Life, Institute for Material Testing, 2011)
This paper investigates the plunge stage using numerical modeling. A three-dimensional finite element model (FEM) of the plunge stage is developed using the commercial code ABAQUS to study the thermo-mechanical processes ...
Functionalization of PLA Aerogels with TiO2 Nanoparticles / Funkcionalizacija PLA aerogelova pomoću TiO2 nanočestica
(Savez inženjera i tehničara Srbije, 2021)
This study was aimed to prepare material with high porosity and photocatalytic activity by immobilization of TiO2 nanoparticles (NPs) onto poly(lactic acid) (PLA) aerogels. PLA aerogels were prepared in three steps: (1) ...
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 ...
EFFECT OF NON-THERMAL PLASMA ON CELLULOSE CRYSTALLINITY AND LIGNIN CONTENT IN CORN STALKS / UTICAJ TRETMANA NETERMALNOM PLAZMOM NA KRISTALINIČNOST CELULOZE I SADRŽAJ LIGNINA U KUKURUZNOJ STABLJICI
(Journal on Processing and Energy in Agriculture, 2022)
Lignocellulosic biomass is a cheap raw material that, thanks to its high carbohydrate content, can be used in fermentation to
produce biofuels, biogas and other compounds. Its complex structure, including cellulose, ...
Influence of whey proteins addition on mechanical stability of biopolymer beads with immobilized probiotics / Uticaj dodatka proteina surutke na mehaničku stabilnost biopolimernih nosača sa imobilisanim probioticima
(Savez inženjera i tehničara Srbije, Beograd, 2015)
Biopolymer carriers are widely used for immobilization of the bioactive compounds and different type of the cells. The aim of this study was to analyze influence of whey proteins addition on mechanical strength of Ca-alginate ...
Decreasing of water absorptiveness of paper by coating nanofibrillated cellulose films
(Engineers Society for Corrosion, 2021)
Nanofibrillated films based on TEMPO-oxidized cotton linters were applied to reduce the hydrophilic properties of paper. For this purpose, aqueous dispersions of nanofibrillated cellulose of different composition: 1 and ...
Total petroleum hydrocarbons distribution and health risk assessment of soil in the Niš railway junction
(Naučno-stručno društvo za zaštitu životne sredine Srbije, ECOLOGICA, 2020)
A particularly high pollution level of total petroleum hydrocarbons (TPH) was observed in
the soil at the railway junction in the city of Niš (Serbia). The TPH level in most of the
studied soil samples exceeded the limit ...
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 ...
