Fractal analysis of physical adsorption on surfaces of acid activated bentonites from Serbia
(Association of the Chemical Engineers of Serbia, 2008)
Solid surfaces are neither ideally regular, that is, morphological and energetically homogeneous, nor are they fully irregular or fractal. Instead, real solid surfaces exhibit a limited degree of organization quantified ...
Bacterially generated Fe2(SO4)3 from pyrite, as a leaching agent for heavy metals from lignite ash / Bakterijski generisani Fe2(SO4)3 iz pirita kao agens za luženje elektrofilterskog pepela termoelektrane iz procesa sagorevanja lignita
(Serbian Chemical Society, 2007)
Investigations of heavy metals from lignite ash, which is a coal combustion by-product, have for years been very interesting from different aspects of environmental protection. In this study, the possibility of microbiological ...
Do altered activities of superoxide dismutases and the level of NF-κB modulate the effects of gamma radiation in HeLaS3 cells?
(Serbian Chemical Society, 2007)
Most experimental models, including cell culture studies, have demonstrated that over-expression of manganese superoxide dismutase (MnSOD) in cells bearing a carcinoma phenotype has anti-proliferative and tumour suppression ...
Preparation and characterization of two types of covalently immobilized amyloglucosidase / Dobijanje i karakterizacija dva tipa imobilizovane amiloglukozidaze
(Serbian Chemical Soc, Belgrade, 2005)
Amyloglucosidase from A. niger was covalently immobilized onto poly( GMA-co-EGDMA) by the glutaraldehyde and periodate method. The immobilization of amyloglucosidase after periodate oxidation gave a preparate with the ...
Carbon-supported hydrous ruthenium oxide composite as electrochemical supercapacitors. 2. Capacitive Properties of Carbon Black Support / Kompozitni materijal hidratisani rutenijum oksid / ugljenik kao elektrohemijski superkondenzator 2. Kapacitivne osobine ugljeničnog substrata
(Association of Chemical Engineers of Serbia, 2007)
Preparation of hydrous ruthenium oxide/carbon black nanocomposite material was performed by the impregnation method starting from hydrous RuO2 sol as a precursor. Black Pearls 2000 (R) (BP) and Vulcan (R) XC-72 R (XC) was ...
Characterization and corrosion properties of electrodeposited Ni-W alloys / Karakterizacija i korozione karakteristike elektrohemijski taložene legure Ni-W
(Serbian Chemical Society, 2001)
Ni-W alloys electrodeposited from citrate solution consist of three different phases, which are all present in high W-content alloys: a solid solution of W in a Ni matrix; an intermetallic compound Ni4W, as well as another ...
Influence of thermal treatment on polyphenolic compounds and antioxidant properties of Quercus robur kernels / Uticaj termičkog tretmana na polifenolne sastojke i antioksidantna svojstva semena lužnjaka, Quercus robur
(Pharmaceutical Association of Serbia, Belgrade, Serbia, 2006)
Polyphenolic compounds and antioxidant properties of dried MeOH extracts of native (QN) and thermally treated (QT) kernels of English Oak, Quercus robur were investigated. The content of total and simple polyphenols and ...
Homology modeling of protein structure / Homologo modelovanje strukture proteina
(Srpsko hemijsko društvo, Beograd, 2009)
Knowledge of three-dimensional protein structure is of the paramount importance for determination of receptor and enzyme action mechanism in interaction with other molecules. In spite of growing number of solved 3D protein ...
New method for monitoring of the oxygen reduction process in aqueous solutions / Nova metoda za monitoring procesa redukcije kiseonika u vodenim rastvorima
(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2009)
Composite electrode material based on NaX zeolite and silver dispersed both inside zeolite cavities and between the zeolite crystals, in nitrogen purged 0.1M NaOH solution, yielded the cyclic voltammograms corresponding ...
Prediction of the particle circulation rate in a draft tube spouted bed suspension dryer / Predviđanje cirkulacije čestica u sušioniku za suspenzije sa modifikovanim fontanskim slojem
(Serbian Chemical Society, 2006)
A model for predicting the particle circulation rate in a draft tube spouted bed dryer with inert particles is proposed and verified. The calculation algorithm requires three input values: the gas velocity in the draft ...
