Processing and characterization of UHMWPE composite fibres with alumina particles in poly(ethylene-vinyl acetate) matrix
(Sage Publications Ltd, London, 2018)
Processing of hybrid composites represents a challenge for engineers where the aim is to establish compatibility among several materials. The aim of this study is to evaluate the effects of different sizes and morphologies ...
Influence of the Fe(III): Modified clinoptilolite on phosphorus leaching from different soil types / Uticaj Fe(III)- modifikovanog klinoptilolita na izluživanje fosfora iz različitih vrsta zemljišta
(Engineering Society for Corrosion, Belgrade, Serbia, 2016)
Influence of the iron(III)-modified clinoptilolite (FeCLI) on phosphorus leaching from two different Norwegian soil types (sand and clay loam soil) was studied using a column system at room temperature. FeCLI was used in ...
Electrophoretically deposited hydroxyapatite-based composite coatings loaded with silver and gentamicin as antibacterial agents
(Srpsko hemijsko društvo, Beograd, 2019)
Increasing need for improved, compatible bone tissue implants led to the intensive research of novel biomaterials, especially hydroxyapatite (HAP)-based composite materials on titanium and titanium alloy surfaces. Owing ...
Inventive level as a basis for the assessment of scientific contribution of inventors / Inventivni nivo pronalaska kao osnov za procenu naučnog doprinosa pronalazača
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, 2019)
The history of invention reveals that the most important inventions were derived from experiments by which their authors contributed to the discovery of previously unknown natural phenomena. So the question arises as to ...
Salt template zirconia reinforcing particles as possible reinforcement for PMMA matrix composite
(Sage Publications Ltd, London, 2019)
To obtain flakes like zirconia particles at relatively low temperature, the synthesis method for producing zirconia particles on the surface of salt particles that serve as a template is examined. The produced particles ...
In vitro micropropagation of fruits: Economic efficiency of application / Razmnožavanje voćaka mikropropagacijom in vitro - ekonomska efikasnost primene
(Naučno voćarsko društvo Srbije, Čačak, 2015)
Aspects of rationalization and the introduction of so-called ‘low cost’ technology of micropropagation and wider applicability for commercial purposes in the field of pomology, were investigated in this paper. The application ...
The oxidation of anthraquinone dye using HRP immobilized as a cross-linked enzyme aggregates / Oksidacija antrahinonskih boja peroksidazom iz rena imobilisanom u obliku umreženih enzimskih agregata
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2016)
Finding a sustainable and ecofriendly methods for recalcitrant synthetic dyes removal is a researchers major challenge. A carrier-free technique for commercial HRP immobilization is a focus of the present study. The ...
Polyphenols extraction from plant sources
(Institute for Medicinal Plants Research "Dr. Josif Pancic", 2017)
Different conventional (maceration and heat-assisted extraction) and new alternative techniques (ultrasound-assisted and microwave-assisted extractions) have been developed for the extraction of polyphenols compounds from ...
Success Rate of Individual Pollinizers for the Pear Cultivars "Ingeborg" and "Celina" in a Nordic Climate
(MDPI, Basel, 2020)
Norwegian pear production is low due to climatic limitations, a lack of well-adapted cultivars and suitable pollinizers. However, nowadays it is increasing as a result of newly introduced and bred pear cultivars. Since ...
LT - contradiction matrix / LT - matrica kontradiktornosti
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, 2021)
Altschuller's Contradiction Matrix and Bartini-Kuznetsov's LT - Table represent two different tools for solving inventive problems based on the same dialectical principle. It starts from the premise that there are ...
