Mechanochemically assisted solid-state and citric acid complex syntheses of Cu-doped sodium cobaltite ceramicsh
(Elsevier Science Sa, Lausanne, 2015)
In the last decade, the sodium cobaltite ceramic became a promising candidate for potential thermoelectric applications, because of its large thermopower and low resistivity. In this work, polycrystalline samples of ...
Oxidized Cotton as a Substrate for the Preparation of Hormone-Active Fibers-Characterization, Efficiency and Biocompatibility
(Korean Fiber Soc, Seoul, 2015)
Oxidized cellulose has a long history of safe and effective use in medical applications. In this paper, research has been directed towards obtaining hormone-active cellulose fibers in the form of an artificial insulin ...
Hemp (Cannabis sativa) fibers as biosorbents and precursor for carbon sorbent production / Vlakna konoplje (Cannabis sativa) kao biosorbenti i sirovine za proizvodnju ugljeničnih sorbenata
(Union of Textile Engineers and Technicians of Serbia, Belgrade, 2015)
Short and entangled hemp fibers, obtained as a waste from textile industry, were used as efficient biosorbent and low-cost precursor for carbon sorbent production. In order to obtain the biosorbents with better sorption ...
Quality, sources and balancing of iron and steel scrap / Kvalitet, izvori i bilansiranje otpadaka gvožđa i čelika
(Savez inženjera i tehničara Srbije, Beograd, 2015)
Besides iron ore, the main raw material of iron and steel production is steel scrap. This paper presents the quality and sources of creation the iron and steel scrap and estimation of their creation in the future. The ...
Design of novel multifunctional Oxaprozin delivery system based on dual-sensitive poly(2-hydroxypropyl acrylate/itaconic acid) hydrogels
(Elsevier Science Bv, Amsterdam, 2015)
Series of novel dual-sensitive poly(2-hydroxypropyl acrylate/itaconic acid) hydrogels were designed as multifunctional drug delivery system which can provide several advantages including drug protection, self-regulated ...
Surface characterization of mesoporous carbon cryogel and its application in arsenic (III) adsorption from aqueous solutions
(Elsevier, 2015)
Resorcinol-formaldehyde (RF) cryogels were synthesized by sol-gel polycondensation of resorcinol with formaldehyde and freeze-drying was carried out with t-butanol. Carbon cryogel (CC) was obtained by pyrolyzing RF cryogels ...
Estimation of GHG emission in Serbia for period 1995-2013 using recurent neural networks / Emisije gasova staklene bašte u Srbiji za period 1995-2013. godina primenom rekurentnih neuronskih mreža
(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2015)
The aim of this work was to create an ANN model for the prediction of GHG emissions in the Republic of Serbia in the period 1995-2013. Because of the lack of GHG emission data and inputs for Serbia, the ANN model was ...
Modeling of ammonia emission in the USA and EU countries using an artificial neural network approach
(Springer Heidelberg, Heidelberg, 2015)
Ammonia emissions at the national level are frequently estimated by applying the emission inventory approach, which includes the use of emission factors, which are difficult and expensive to determine. Emission factors are ...
Production of activated carbon derived from waste hemp (Cannabis sativa) fibers and its performance in pesticide adsorption
(Elsevier, Amsterdam, 2015)
The main objective of this work was to find optimal production parameters for the preparation of activated hemp fibers (ACh) with good adsorption properties toward pesticides. In order to examine the role of manufacturing ...
Ekstrakcija odabranih lekova na višeslojnim ugljeničnim nanocevima / Extraction of selected pharmaceuticals on multiwalled carbon nanotubes
(Beograd : Srpsko hemijsko društvo = Serbian Chemical Society, 2015)
Predmet ovog rada bio je ispitivanje mogućnosti primene višeslojnih ugljeničnih nanocevi kao sorbenta u metodi ekstrakcije na čvrstoj fazi (eng. solid phase extraction SPE) pri analizi ostataka lekova iz vode. U cilju ...
