Hemp fibers (Cannabis sativa) impregnated by Ca-alginate gel as a novel biosorbent for the removal of Pb(II) and Zn(II) ions / Novi biosorbent na bazi vlakna konoplje (Cannabis sativa) i Ca-alginata za uklanjanje jona olova i cinka
(Engineering Society for Corrosion, Belgrade, Serbia, 2018)
In this paper the possibility of implementing the new biosorbent composed of chemically modified short hemp fibers impregnated with alginate gel for adsorption of lead(II) and zinc (II) ions was investigated. Waste hemp ...
Animal models in biocompatibility assessments of implants in soft and hard tissues / PRIMENA ANIMALNIH MODELA U PROCENI BIOKOMPATIBILNOSTI IMPLANTATA ZA TVRDA I MEKA TKIVA
(University of Belgrade, Faculty of Veterinary Medicine, 2022)
The ethical dilemmas of using animals as in vivo models in preclinical and clinical examinations have been increasingly present in recent decades. Small laboratory animals (rats, rabbits) will continue to be used because ...
Characterisation of the nanotubular oxide layer formed on the ultrafine-grained titanium
(Savez inženjera metalurgije Srbije, Beograd, 2018)
Commercially pure titanium (cpTi) and titanium alloys are metallic implant materials usually used in dentistry and orthopaedics. In order to improve implant properties, Ti-based materials may be surface modified by different ...
Effect of plasma hardfacing and carbides presence on the occurrence of cracks and microcracks
(Society for Structural Integrity and Life, Institute for Material Testing, 2018)
Presented is the effect of plasma hardfacing (or just hardfacing) and carbides presence on the occurrence of cracks and microcracks in the welded layer. The reasons behind this phenomenon are analysed and explained. In ...
Enzymatic synthesis of fructo-oligosaccharides using Pectinex® Ultra SP-L: a study of experimental conditions / Enzimska sinteza frukto-oligosaharida upotrebom Pectinex® Ultra SP-L: ispitivanje uticaja eksperimentalnih uslova
(Institute for Food Technology, 2021)
The obvious benefits of employing prebiotics as functional components in many foods
and feed products have resulted in higher demand for their industrial production, necessitating the
development of more efficient and ...
Immobilization of Aspergillus Niger cellulase onto Lifetech TM carriers and its application in the hydrolysis of sunflower seed meal lignocellulosic fraction / Imobilizacija Aspergillus Niger celulaze na Lifetech TM nosače i primena u reakciji hidrolize lignocelulozne frakcije suncokretove sačme
(Institute for Food Technology, Novi Sad, 2019)
Cellulases are enzymes which catalyse cellulose hydrolysis and are widely used in various industry branches. Lately, their application in treatment of different agroindustrial waste materials which could serve for fuel ...
Corrosion resistance of welded pipe in oil wells / Otpornost na koroziju zavarenih cevi u naftnim bušotinama
(Engineering Society for Corrosion, Belgrade, Serbia, 2013)
Steel pipes in oil and gas wells are continuously exposed to the process of corrosion-assisted elevated temperatures and pressures prevailing in the interior of the tube. Corrosion can lead to significant reduction of ...
Influence of an accumulative roll bonding (ARB) process on the properties of AA5083 Al-Mg alloy sheets
(Association of Metallurgical Engineers of Serbia AMES, 2014)
In this study, fully annealed AA5083 type alloy sheets with 1 mm in thickness
were processed by accumulative roll bonding (ARB) at room temperature, up to 6 ARB
cycles. It was found that microstructure was refined and ...
