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 ...
Effect of solution pH on crack initiation and propagation in glass-polyester pipes subjected to impact
(Wiley-Blackwell, Hoboken, 2012)
The objective of this study was the determination of the influence of alkaline and acidic solutions on the impact properties of glass-polyester composite pipes. First, the impact test was performed on virgin samples (without ...
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 ...
Polyimide structures for micro-electro-mechanical system (mems) - based applications. / Polimidne konzole za primenu u mikro-elektro-mehaničkim (mems) sistemima
(Univerzitet u Beogradu, Tehnološko-metalurški fakultet, 2016)
This Ph.D. thesis studies and experimentally examines applicability of thin polymer films as structural substitutes for crystaline Si in bimorph MEMS structures. The two shapes (bi - morph) and transient state between the ...
The Prediction of Heavy Metal Permeate Flux in Complexation-Microfiltration Process: Polynomial Neural Network Approach
(Springer International Publishing Ag, Cham, 2019)
Membrane filtration techniques are distinguished among methods for wastewater treatment and fully correspond to the requirements of the green concept of chemistry and production. The limiting factor for greater application ...
Retention modelling of ion chromatography for cations in atmospheric aerosols
(Belgrade : Vinča Institute of Nuclear Sciences, 2016)
Concentrations of six water-soluble cations (lithium, sodium, ammonium, potassium, magnesium and calcium) in atmospheric
aerosol samples, collected in a suburb of Belgrade (Serbia), were determined by ion chromatography ...
Kinetics and thermodynamics of Mo(VI) and Re(VII) sorption on amino-functionalized magnetic polymer
(Belgrade : Society of Physical Chemists of Serbia, 2018)
Kinetics and thermodynamics of Mo(VI) and Re(VII) sorption onto amino
functionalized magnetic poly(glycidyl methacrylate-co-ethylene glycol
dimethacrylate) [mPGME-deta] at 298 K and pH=4.0 were investigated. It
was shown ...
Comparative analysis of mathematical models for supercritical extraction simulation from industrially valuable lamiaceae herbs
(Wiley, Hoboken, 2014)
The present study was aimed to compare different mathematical models used to simulate process of supercritical extraction from commercially important Lamiaceae herbs. Supercritical extractions with carbon dioxide from ...
The potential use of aby-6 starter culture in fermentation of soy based substrates
(Novi Sad : Institute of Food Technology, 2016)
The aim of this study was selection of optimal fermentation parameters (inoculum level and temperature) for production of fermented soy milk based beverage, using starter culture ABY-6 specially designed for yogurt production. ...
