Silicon nanostructuring by Ag ions implantation through nanosphere lithography mask
(Elsevier Science Bv, Amsterdam, 2019)
Nanosphere lithography is an effective technique for high throughput fabrication of well-ordered patterns on large areas. This study reports on nanostructuring of silicon samples by means of Ag ions implantation through ...
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 ...
Migration of cypermethrin to and through the PET containers and artificial neural network-based estimation of its emission
(Springer Verlag, 2019)
Nowadays, the extensive use of pesticides in crops production puts a significant challenge to minimize its side effects along with safe production, storage, and after-use treatment. This paper reports results related to ...
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 ...
Thermal cycling behaviour of plasma sprayed nicr-al-co-y2o3 bond coat in thermal barrier coating system
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2019)
The aim of this study was to investigate the thermal cycling behaviour of NiCr-Al-Co-Y2O3 bond coating in thermal barrier coating (TBC) system with ZrO2-MgO as a top coating. The coatings were deposited by atmospheric ...
Contributions of impregnated silver nanoparticles to ideality increase of filtration material in human respiratory protection / Doprinos impregnisanih nanočestica srebra porastu idealnosti filtrirajućih sredstava respiratorne zaštite
(Engineering Society for Corrosion, Belgrade, Serbia, 2019)
A technical contradiction arises when within a system one parameter improves thus automatically causing another one to worsen. In a situation like this, instead of a usual acceptance of compromise which leads to optimization ...
Abnormalities in the ovule development of the European plum cultivar 'Pozna Plava' in the days following anthesis
(Elsevier Science Bv, Amsterdam, 2019)
Factors such as the stage of ovule maturity and longevity at flowering, when the stigma is able to receive the pollen, are significant in terms of fruit set. Various abnormalities during ovule development can often limit ...
The influence of synthesis conditions on the redox behaviour of LiFePO4 in aqueous solution
(Elsevier Science Sa, Lausanne, 2019)
To contribute to the knowledge on the influence of synthesis procedure on the intercalation kinetics of lithium ions into phospho-olivines, LiFePO4/C composite samples (LFPC) were synthesized in two ways, the first one in ...
Supercritical co2 impregnation of gelatin-chitosan films with clove essential oil and characterization thereof
(Savez hemijskih inženjera, Beograd, 2019)
Supercritical CO2 impregnation process was used for the first time to fabricate biodegradable gelatin-chitosan (G/Ch) films containing dove oil (CO) for potential use in active food packaging. All the impregnations were ...
Doping of TiO2 nanotubes with nitrogen by annealing in ammonia for visible light activation: Influence of pre- and post-annealing in air
(Elsevier Ltd, 2019)
The ∼60 nm wide and ∼2 μm long TiO2 nanotubes were obtained by anodization of Ti films sputtered on F-doped tin oxide glass. For N-doping the samples were annealed in ammonia atmosphere. The effect of pre- and post-annealing ...
