Sorption of Ni2+ by different synthetic hydroxyapatite
(Belgrade : The Society of Physical Chemists of Serbia, 2004)
Two hydroxyapatite (HAP) samples of different crystallinity were studied as a
nickel immobilization matrix. Sorption isotherms were obtained by batch equilibration
method, in the concentration range 1.
10-4 – 8.
10-3 ...
Equilibrium and kinetic studies of heavy metal retention by hydroxyapatite
(Belgrade : Institute of Technical Sciences of SASA, 2005)
Sorption capacities and kinetics of toxic heavy metals sorption by synthetic, wellcharacterized, hydroxyapatite (HAP) was studied using the batch technique. Initial concentration
of Pb2+, Zn2+, Cd2+ and Sr2+ solutions, ...

(Belgrade : The Society of Physical Chemists of Serbia, 2004)
This paper describes the application of artificial neural networks (ANNs) method
to the modeling of 13 polycyclic aromatic hydrocarbons (PAHs)retentionsin temperature - programmed gas chromatography.The ANN method used ...
Glass transition temperature determination of macroporous copolymer by inverse gas chromatography
(Belgrade : Institute of Technical Sciences of SASA, 2003)
The glass transition temperature, Tg, of crosslinked macroporous glycidyl
methacrylate, GMA, based copolymer was studied by inverse gas chromatography at zero
surface coverage (IGC-ZC). The specific retention volumes, ...
Ispitivanje hromatografskog ponašanja nekih azo boja derivata piridona / Chromatographic behaviour of some azo dyes pyridone derivates
(Beograd : Srpsko hemijsko društvo, 2001)
Azo jedinjenja predstavijaju nejveéu grupu industrijskih boja, kako po broju, tako i po obimu proizvodje. Azo boje obavezno sardze azo grupu (-N=N-) vezanu za aromatican prsten. Primenjuju se u tekstilnoj industriji, ali ...
The influence of pH on Pb2+, Cd2+, Zn2+ and Sr2+ removal from aqueous solutions by hydroxyapatite
(Belgrade : Association of Chemical Engineers, 2005)
Sorption of different ionic species, especially heavy metals, on calcium-hydroxyapatite
Ca10(PO4)6(OH)2, (HAP) and other apatite minerals plays an important role in environmental
chemistry and practical applications of ...
Analysis of in vivo substitution of bone tissue by HAp/PLLA composite biomaterial with PLLA of different molecular weights using FTIR spectroscopy
(Uetikon-Zuerich : Trans Tech Publ, 2000)
Hydroxyapatite/poly-L-lactide (HAp/PLLA) composite biomaterial with PLLA of 50,000 and 430,000 g/mole molecular weight was studied in vivo. The biocomposite with PLLA of both molecular weights was implanted into mice and ...
Bioethanol Production from Corn Meal Hydrolyzates by Immobilized Saccharomyces cerevisiae var. ellipsoideus
(2008 Joint Central European Congress of the 4th Central European Congress on Food, CEFood 2008 and 6th Croatian Congress of Food Technologists, Biotechnologists and Nutritionists, 2008)
Bioethanol can be produced by fermentation of sugars from waste agricultural materials. In this process immobilized yeast offer advantage over free cell suspension with regard to ethanol productivity, fermentation rate and ...
Physico-chemical properties of polymeric and composite bioresorbable barrier membranes
(Belgrade : Institute of Technical Sciences of SASA, 2003)
Bioresorbable barrier membranes are widely used in dentistry and maxillofacial
surgery. When the membranes are placed over bony defects and closely adapted to the
surrounding bone face, an environment that prevents ...
Optimization of a neural network model for signal-to-background prediction in gamma-ray spectrometry
(Belgrade : Vinča Institute of Nuclear Sciences, 2004)
The artificial neural network (ANN) model was optimized for the prediction of signal-tobackground (SBR) ratio as a function of the measurement time in gamma-ray
spectrometry. The network parameters: learning rate (α), ...
