Theoretical and experimental investigation of geometry and stability of small potassium-iodide KnI (n=2-6) clusters
(Wiley, Hoboken, 2019)
Small heterogeneous potassium-iodide clusters are investigated by means of ab initio electronic structural methods together with experimental production and detection in mass spectrometry. Experiments were done by using ...
Study on Transglucosylation Properties of Amylosucrase from Xanthomonas campestris pv. Campestris and Its Application in the Production of alpha-Arbutin
(MDPI, Basel, 2019)
alpha-Arbutin (4-hydroquinone-alpha-D-glucopyranoside), an effective skin-lightening agent due to its considerable inhibitory effect on human tyrosinase activity, is widely used in the pharmaceutical and cosmetic industries. ...
Molecular and Supra-Molecular Structural Ordering of Wheat Starch-OSA Modified Waxy Maize Starch Mixtures During Storage
(Wiley-VCH Verlag Gmbh, Weinheim, 2019)
The influence of waxy maize OSA starches on the retrogradation kinetics of wheat starch pastes is investigated using dynamic oscillatory rheological and differential scanning calorimetry (DSC) measurements. Total starch ...
Theorems of the Alternative for Systems of Convex Inequalities
(Springer, Dordrecht, 2019)
Systems of convex inequalities in function spaces are considered. Solvability conditions are obtained in the form of a theorem of the alternative. We revisit some results from the literature where such theorems are incorrect. ...
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 ...
Characterization of MgAl2O4 Sintered Ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2019)
Single phase MgAl2O4 was made from a one-to-one molar ratio of MgO and Al2O3 powders mixed using ball-milling. Mixtures of MgO and Al2O3 were subsequently treated in planetary ball mill for 30, 60, 90 and 120 minutes in ...
Phenolic Extracts from Vaccinium corymbosum L. Loaded in Microemulsions and Liposomes as Enhancers of Olive Oil Oxidative Stability
(De Gruyter Poland Sp Zoo, Warsaw, 2019)
Natural phenolic compounds are recognized as bioactive ingredients in food but can also have a role as effective alternatives to synthetic antioxidants in stability improvement of foods prone to oxidation, such as edible ...
Novel Approach for Determination of Potentially Toxic Elements via ICP-OES in Aqueous Solutions of Building Materials with Industrial Byproduct Addition
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2019)
New global tendencies for waste materials reusing in building materials are imposing the request for improved performances of chemical analysis methods and the improvements of matrices used. A new method for optical emission ...
Color stability of bulk-fill and universal composite restorations with dissimilar dentin replacement materials
(Wiley, Hoboken, 2019)
Objective To determine color changes in bulk-fill composite and universal composite restorations with dissimilar dentin replacement materials in extracted teeth after staining in red wine. Materials and Methods Cylindrical, ...
Optical properties and fluorescence of quantum dots CdSe/ZnS-PMMA composite films with interface modifications
(Elsevier Science Bv, Amsterdam, 2019)
Processing and characterization of polymer nanocomposites based on poly (methyl methacrylate) (PMMA) matrix with embedded core-shell CdSe/ZnS quantum dots (QD's) were presented in this work. The aim is to preserve the ...
