Opportunities, perspectives and limits in lactic acid production from waste and industrial by-products
(Savez hemijskih inženjera, Beograd, 2016)
In line with the goals of sustainable development and environmental protection today great attention is directed towards new technologies for waste and industrial by-products utilization. Waste products represent potentially ...
Cracking caused by cutting of plasma-sprayed hydroxyapatite coatings and its relation to the structural features of coatings deposited at different initial substrate temperatures
(Savez hemijskih inženjera, Beograd, 2017)
The present study estimated the cracking phenomenon in as-plasma-sprayed hydroxylapatite coatings (HACs) after they were being subjected to the severe cutting conditions in the direction perpendicular to the coating/substrate ...
Image analysis as a useful tool for fast detection of dimensional and structural changes of poly(ethylene terephthalate) containers
(Savez hemijskih inženjera, Beograd, 2018)
The aim of this paper is to present image analysis as a useful technique for fast, reliable and non-destructive detection of dimensional and structural changes in polymers. The possibility of applying image analysis was ...
Treatment of the acidic effluent from a copper smelter by flotation tailings
(Savez hemijskih inženjera, Beograd, 2019)
Since commissioning in 1961, the copper mine Majdanpek, a part of the Mining and Smelting Complex Bor (RTB Bor), produced approximately 378 million tons of flotation tailings. Semiquantitative mineralogical analysis of the ...
New spirohydantoins derived from beta-tetralone: design, synthesis and evaluation of their pharmacokinetically relevant propertie
(Savez hemijskih inženjera, Beograd, 2019)
To create new anticonvulsant drugs, two series of spirohydantoins derived from beta-tetralone bearing a 4-substituted benzyl group (1a-1g) or a 2-(4-substituted phenyl)-2-oxoethyl group (2a-2f) in position 3 of the hydantoin ...
Novel composite zinc-alginate hydrogels with activated charcoal aimed for potential applications in multifunctional primary wound dressings
(Savez hemijskih inženjera, Beograd, 2019)
Composites based on Zn-alginate hydrogels in the form of beads were produced by extrusion of a suspension containing 0.5 % w/w of alginate and 20 % w/w of activated charcoal (AC) with the intent to simultaneously release ...
Immobilization of Chaga extract in alginate beads for modified release: simplicity meets efficiency
(Savez hemijskih inženjera, Beograd, 2019)
Chaga (Inonotus obliquus) is a parasitic fungus, which has been used in traditional medicine in Russia and other northern European countries in the treatment of cancer, gastrointestinal andliver diseases. It has been a ...
Preliminary studies on controlled release of acetylsalycilic acid from membrane module
(Association of Chemical Engineers of Serbia, 2004)
Controlled swelling and degradation studies of alginate microbeads in dilute natrium citrate solutions / Ispitivanje mogućnosti kontrolisanog bubrenja i razgradnje alginatnih mikročestica u razblaženim rastvorima natrijum-citrata
(Association of Chemical Engineers of Serbia, 2010)
Alginate hydrogels are widely used in biomedicine due to alginate availability, hydrophilic nature, biocompatibility and biodegradability. Alginate microbeads are particularly attractive for applications in pharmacy and ...
