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 ...
Antimikrobna aktivnost bagremovog meda
(Технолошки факултет, Лесковац, 2015)
Antibakterijsko, antifungicidno i antivirusno dejstvo meda poznato je od davnina i najvećim delom potiče od vodonik-peroksida, koji nastaje aktivnošću enzima glukoza-oksidaza koji pčele izlučuju u med. Pored vodonik-peroksida, ...
Failure resistance of drilling rig casing pipes with an axial crack
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
Working conditions of casing pipes in drilling rigs can significantly influence the initiation and development of damage in the material, and therefore also the safe service of the entire system. In this work, an integrity ...
Melt Dispersion Technique for Encapsulation
(CRC Press, 2015)
Encapsulation involves the coating or entrapment of a pure material or a mixture into another material. The coated or entrapped material, usually a liquid, is known as the “core” or “active” material, while the coating ...
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 ...
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 ...
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 ...
