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 ...
Advantage of use of activated flux-cored wire instead of solid wire with the mag welding process from the mechanical properties aspect
(Croatian Metallurgical Soc, Zagreb, 2013)
The objective of this paper is the analysis and evaluation of the quality of the new flux-cored wire designed for the MAG welding process that was developed and produced using special laboratory equipment. Experimental ...
Smanjenje sadržaja boje u otpadnim vodama: korišćenje azo piridonskih boja za bojenje vune / Reducing the effluent load: azo pyridone dyes used for dyeing wool
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS), 2021)
Budući da tekstilna industrija predstavlja jednu od glavnih grana industrije, razvoj globalne ekonomije je direktno povezan sa razvojem tekstilne industrije. Sa druge strane, razvoj novih boja je od ključnog značaja za ...
Free radicals' scavenging capacity of Thymus serpyllum L. extracts depending on applied extraction conditions and extraction techniques
(Serbian Nutrition Society, Belgrade, 2021)
Polyphenols, as plant secondary metabolites, achieve strong antioxidant capacity by scavenging free radicals, chelating metals, and interacting with lipid membranes, proteins and nucleic acids. The aim of the present study ...
Removal of hexavalent chromium from wastewaters using nano zero-valent iron produced by oak leaf extract
(Zbornik radova 42. Međunarodnog stručno-naučnog skupa Vodovod i kanalizacija ´21, 2021)
Наночестице елементарног гвожђа (nano zero valent iron, nZVI) се све више користе за уклањање различитих загађујућих материја из воде захваљујући великој активности, нетоксичности и релативно ниској цени. Да би процес ...
ECOLOGICAL RISK ASSESSMENT OF ASPARTAME AND NEOTAME IN RIVER SEDIMENTS
(Belgrade : The Academy of Applied Technical Studies "Belgrade", 2023)
Artificial sweeteners are high-priority emerging contaminants that are widespread in surface waters worldwide as a result of municipal wastewater discharges into the aquatic environment. Given that these substances can ...
Breaking news: Empirical formulas, molar masses, biosynthesis reactions and thermodynamic properties of virus particles - Biosynthesis and binding of Omicron JN.1 variant of SARS-CoV-2 / Ударне вести: емпиријске формуле, моларне масе, реакције биосинтезе и термодинамичке особине вирусних честица: биосинтезе и везивања Omicron JN.1 варијанте SARS-CoV-2
(Serbian Chemical Society, 2024)
Breaking news are usually disturbing. Natural disasters, wars, epidemics, etc., are reported as breaking news. This paper reports a decreased danger of spreading of epidemics caused by the JN.1 variant, since analyses ...
Sinthesis and Characterization of Hydroxyapatite and Fluorapatite Powders
(Belgrade : ETRAN SocietyBelgrade : Academic Mind, 2019)
The biomaterial powders of hydroxyapatite (HAp)
and fluorapatite (FAp) were synthesized by a hydrothermal
method. Powders were analyzed by energy-dispersive X-ray
spectroscopy (EDS), field emission scanning electron ...
Two-phase electro-magneto-fluid dynamics model and its computational fluid dynamics implementation
(AIP Publishing, 2024)
In this work, we present a two-phase electro-magneto-fluid dynamics (EMFD) model that merges electromagnetics and fluid dynamics. The model is suitable for use in computational fluid dynamics (CFD) software and was ...
Effect of ultrasound and chemical pretreatments on L-ascorbic acid of dried bell pepper (Capsicum annuum) studied by factorial design
(University of Belgrade‐Faculty of Agriculture, 2022)
Drying is one of the methods for the preservation of fruits and vegetables [1]. Peppers are still
dried in open sunlight, although this method has many shortcomings (long drying time,
microbial contamination, depending ...
