Fractal analysis of bentonite modified with heteropoly acid using nitrogen sorption and mercury intrusion porosimetry / Fraktalna analiza bentonita modifikovanog heteropoli kiselinom korišćenjem podataka sorpcione analize i živine porozimetrije
(Serbian Chemical Society, 2011)
Experimental adsorption isotherms were used to evaluate the specific surface area and the surface fractal dimensions of acid-activated bentonite samples modified with a heteropoly acid (HPW). The aim of the investigations ...
Olive leaf extract modulates cold restraint stress-induced oxidative changes in rat liver / Ekstrakt lista masline moduliše oksidativne promene indukovane imobilizacionim stresom ubrzanim hladnoćom u jetri pacova
(Serbian Chemical Society, 2011)
Recently, the beneficial effects of different single doses of standardized dry olive (Olea europaea L.) leaf extract (OLE) in cold restraint stress (CRS)-induced gastric lesions in rats and its influence on oxidative ...
Investigation of the bioremediation potential of aerobic zymogenous microorganisms in soil for crude oil biodegradation / Ispitivanje bioremedijacionog potencijala aerobnih zimogenih mikroorganizama iz zemljišta u biodegradaciji sirove nafte
(Serbian Chemical Soc, Belgrade, 2011)
The bioremediation potential of the aerobic zymogenous microorganisms in soil (Danube alluvium, Pančevo, Serbia) for crude oil biodegradation was investigated. A mixture of paraffinic types of oils was used as the substrate. ...
Removal of aqueous phenol and phenol derivatives by immobilized potato polyphenol oxidase / Uklanjanje fenola i fenolnih derivata iz vode imobilizovanom polifenol-oksidazom iz krompira
(Serbian Chemical Soc, Belgrade, 2011)
Phenols containing halogens, which tend to deactivate the aromatic nuclei, constitute a significant category of highly toxic and difficult-to-degrade pollutants, which arise from a wide variety of industries. The main ...
Synthesis of 5-(substituted phenylazo)-6-hydroxy-4-methyl-3-cyano-2-pyridones from ethyl 3-oxo-2-(substituted phenylazo)butanoates / Sinteza 5-(supstituisanih fenilazo)-6-hidroksi-4-metil-3-cijano-2-piridona iz etil-3-okso-2-(supstituisanih fenilazo)butanoata
