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. ...
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 ...
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, ...
Size-dependent antibacterial properties of Ag nanoparticles supported by amino-functionalized poly(GMA-co-EGDMA) polymer
(Wiley, Hoboken, 2019)
Size-dependent antimicrobial ability of silver nanoparticles (Ag NPs) supported by amino-functionalized poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) (poly(GMA-co-EGDMA)) macroporous copolymer was tested ...
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. ...
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 ...
Characterisation of peppermint (Mentha piperita L.) essential oil encapsulates
(Taylor and Francis Ltd, 2019)
The aim was to choose the optimal encapsulation system and to incorporate encapsulates loaded with essential oil into the ice cream as a model food product. Methods: Ca-alginate beads were produced by electrostatic extrusion ...
Investigation of Nsingle bondH⋯O interactions in N-monosubstituted caproamide – Ether systems: FT–IR and FT–NIR spectroscopic study
(Elsevier Science Bv, Amsterdam, 2019)
This paper reports FT-IR and FT-NIR spectroscopic study of hydrogen bonding between N-mono-substituted caproamides and different ethers (diethyl ether and tetrahydrofuran) in carbon tetrachloride. With increase in ether ...
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 ...
