(Association of Chemical Engineers of Serbia, 2012)
The aim of this paper is to propose equations for the diffusion of drugs for investigated drug/hydrogel systems using the parameters affecting the transport of drug through poly- (2-hydroxyethylmethacrylate/itaconic acid) ...
Synthesis and characterization of sintered hydroxyapatite/lignin coatings on titanium / Sinteza i karakterizacija sinterovanih hidroksiapatit/lignin prevlaka na titanu
(Association of Chemical Engineers of Serbia, 2012)
To improve corrosion stability and biocompatibility of titanium surface, hydroxyapatite (Ca10(PO4)6(OH)2, HAP) has been used as coated material because it has similar chemical composition as bone tissue. Incorporation of ...
Influence of yarn folding on uv protection properties of hemp knitted fabrics
(Savez hemijskih inženjera, Beograd, 2016)
In the last years the media have highlighted the damage of the ozone layer and the resulting increase of ultraviolet radiation (UVR) reaching the Earth's surface. Prolonged and repeated, both occupational and recreational, ...
Cu(II) immobilization onto a one-step synthesized poly(4-vinylpyridine-co-ethylene glycol dimethacrylate) resin: Kinetics and XPS analysis
(Savez hemijskih inženjera, Beograd, 2016)
Synthesis of an unconventional resin based on 4-vinylpyridine (4-VP) and its Cu(II) sorption behavior were studied. Three samples of macroporous crosslinked poly(4-vinylpyridine-co-ethylene glycol dimethacrylate) (P4VPE) ...
Transport of silver nanoparticles from nanocomposite Ag/alginate hydrogels under conditions mimicking tissue implantation
(Savez hemijskih inženjera, Beograd, 2017)
The aim of this work was to assess phenomena occurring during AgNP transport from nanocomposite Ag/alginate hydrogels under conditions relevant for potential biomedical applications as antimicrobial soft tissue implants. ...
Characterization of dextransucrase from Leuconostoc mesenteroides T3, water kefir grains isolate
(Savez hemijskih inženjera, Beograd, 2017)
The production of dextransucrase (DS) by Leuconostoc mesenteroides T3, novel isolate from water kefir grain, was studied and optimized. Bacterial supernatant reached activity of 3.1 U/ml when the culture was grown at 23 ...
Plate heat exchanger design software for industrial and educational applications
(Savez hemijskih inženjera, Beograd, 2017)
Plate heat exchanger is a type of heat exchanger that uses corrugated metal plates to transfer heat between two fluids. The plate corrugations are designed to achieve turbulence across the entire heat transfer area thus ...
