A rapid test to measure adhesion between optical fibers and ethylene-vinyl acetate copolymer (EVA)
(Elsevier Sci Ltd, Oxford, 2016)
Optical fibers are transported on a drum and on some occasions it is essential to fix them and to keep them fixed to the drum. Adhesives are used in such situations to obtain the best and durable fixation. This research ...
Adsorpcija odabranih lekova i pesticida na rečnom sedimentu / Adsorption of selected pharmaceuticals and pesticides on river sediment
(Beograd : Srpsko hemijsko društvo, 2015)
Zagađujuće materije u životnoj sredini, poput lekova i pesticida ispoljavaju veliki afinitet da se akumuliraju u rečnim sedimentima, tako da rečni sedimenti mogu postati sekundarni izvor zagađenja. Cilj ovog rada bio je ...
Uticaj neselektivnih oksidacionih sredstava na sadržaj uvedenih funkcionalnih grupa i sorpciona svojstva vlakana konoplje / Influence of non-selective oxidation on the surface chemistry and sorption properties of hemp fibers
(Banja Luka : University of Banjaluka, Faculty of Technology, 2018)
U ovom radu ispitivani su uticaji dva različita neselektivna oksidaciona sredstva, vodonik-peroksida
i kalijum-permanganata, na uvedene funkcionalne grupe i sorpciona svojstva modifikovanih
vlakana konoplje. Tokom primene ...
Chocolate as a carrier for cocoa's functional ingredients
(The Diversified Benefits of Cocoa and Chocolate, 2018)
The aim of this chapter was to introduce chocolate as a cocoa carrier of probiotics and bioactive whey protein hydrolysate. This research examined the influence of additional ingredients on the functional properties and ...
Development of Lipid-β-Sitosterol Small Unilamelar Liposomes as Vehicles for Gentisic Acid
(Faculty of Technology, Zvornik, 2019)
Liposomes, as biodegradable, non-toxic and non-immunogenic drug delivery systems, can
provide controlled release of active molecules and their protection from degradation. Therefore,
the aim of the present study was ...
Highly efficient enzymatic acetylation of flavonoids: Development of solvent-free process and kinetic evaluation
(Elsevier Science Bv, Amsterdam, 2017)
Solubility and stability of flavonoid glycosides, valuable natural constituents of cosmetics and pharmaceuticals, could be improved by lipase-catalyzed acylation. Focus of this study was on development of eco-friendly ...
Correlation of particle diameters and determination of important variables for particles obtained by using the electrospray process and alginate solutions
(Zvornik : Faculty of Technology, 2019)
The electrospray process is a process that uses an electric field to influence the liquid dripping out of a capillary tube in order to obtain a reduction in the mean droplet diameter. The theory regarding this process is ...
The Effect of Preparation Method on Ni/Ce/Al Catalyst for High Temperature Water-Gas Shift Reaction
(Key Engineering Materials, 2017)
High temperature water gas shift (HT-WGS) is an important catalytic process connected with reforming process in hydrogen production. Ni/CeO2-Al2O3 (or Al2O3) catalysts were studied in this work on the effect of catalyst ...
Study on the pyrolysis products of two different hardwood lignins in the presence of NiO contained-zeolites
(Elsevier Ltd, 2017)
Several NiO contained-zeolites (NiO/H-ZSM-5, NiO/H-BETA and NiO/H-Y) prepared by a mechanochemical dry milling (MCDM) were tested in the pyrolysis of two hardwood lignins: Eucalyptus (EUC) and a mixture of birch and aspen ...
А crystallographic and theoretical study of intermolecular interactions of newly synthesized spirohydantoins
(Belgrade : Serbian Chemical Society, 2019)
A series of spirohydantoins derived from α-tetralone (Figure 1) was synthesized and the
compounds were characterized using the melting point measurements, FTIR, 1H and 13C
NMR spectroscopic methods. The molecular ...
