Manifestations of dynamic strain ageing in 2090 Al-Li alloy
(International Journal of Materials Research, 2022)
The manifestations of dynamic strain ageing in a commercial 2090 Al - Li alloy were investigated in a wide range of temperatures (-40 to 100 degrees C) and strain rates (4.16x10(-5) to 4.16x10(-3) s(-1) ). Serrated yielding, ...
Towards antimicrobial yet bioactive Cu-alginate hydrogels
(IOP Publishing Ltd, Bristol, 2016)
The simplest approach to enhance alginate hydrogel characteristics and functional properties is to replace the calcium in the process of alginate gelation with other metallic ions which are essential for living systems. ...
Novel Approach for Flavonoid Esters Production: Statistically Optimized Enzymatic Synthesis Using Natural Oils and Application in Cosmetics
(Amer Chemical Soc, Washington, 2019)
The present work describes application of natural triglycerides for lipase-catalyzed esterification of structurally diverse flavonoids-esculin, naringin, and phloridzin. Ester mixtures with laurate, linolenate, or linoleate ...
Bioreactor validation and biocompatibility of Ag/poly(N-vinyl-2-pyrrolidone) hydrogel nanocomposites
(Elsevier Science Bv, Amsterdam, 2013)
Silver/poly(N-vinyl-2-pyrrolidone) (Ag/PVP) nanocomposites containing Ag nanoparticles at different concentrations were synthesized using gamma-irradiation. Cytotoxicity of the obtained nanocomposites was determined by MU ...
Biocompatible and degradable scaffolds based on 2-hydroxyethyl methacrylate, gelatin and poly(beta amino ester) crosslinkers
(Elsevier Sci Ltd, Oxford, 2018)
Gelatin hydrogels have great potential in regenerative medicine but their weak mechanical properties are a major drawback for the load-bearing applications, such as scaffolds for tissue engineering. To overcome this ...
Structural and biological evaluation of lignin addition to simple and silver-doped hydroxyapatite thin films synthesized by matrix-assisted pulsed laser evaporation
(Springer, Dordrecht, 2015)
We report on thin film deposition by matrix-assisted pulsed laser evaporation of simple hydroxyapatite (HA) or silver (Ag) doped HA combined with the natural biopolymer organosolv lignin (Lig) (Ag:HA-Lig). Solid cryogenic ...
Application of whey protein and whey protein hydrolysate as protein based carrier for probiotic starter culture
(Elsevier Sci Ltd, Oxford, 2019)
The main object of study is application of whey protein concentrate (WPC) and whey protein hydrolysate (WPH) for probiotic encapsulation. The controlled enzymatic hydrolysis was applied to change technological properties ...
Influence of fatty acid on lipase-catalyzed synthesis of ascorbyl esters and their free radical scavenging capacity
(Wiley, Hoboken, 2015)
Fatty acid (FA) ascorbyl esters are recently emerging food, cosmetic, and pharmaceutical additives, which can be prepared in an eco-friendly way by using lipases as catalysts. Because they are amphiphilic molecules, which ...
Supercritical carbon dioxide extraction of Trigonella foenum-graecum L. seeds: Process optimization using response surface methodology
(Elsevier Science Bv, Amsterdam, 2016)
Pretreatment of fenugreek (Trigonella foenum-graecum L, Fabaceae) seeds was achieved using the step of defatting and acid hydrolysis. The obtained hydro-isolate (HI) was used as initial feed for diosgenin isolation by ...
Introduction of cleaner production in the tank farm of the Pancevo Oil Refinery, Serbia
(Elsevier Sci Ltd, Oxford, 2010)
This work studies the introduction of cleaner production (UP) in the tank farm of the Pancevo Oil Refinery. From 2003 to 2008, substantial investments in storage technology and equipment were made in order to minimize the ...
