Hydrothermal synthesis of hematite (α-Fe2O3) nanoparticle forms: Synthesis conditions, structure, particle shape analysis, cytotoxicity and magnetic properties
(Journal of Alloys and Compounds, 2019)
In this work, we present the magnetic and structural properties of α-Fe 2 O 3 nanoparticles synthesized by the hydrothermal synthesis method. XRD, FTIR and Raman spectroscopy indicate that the samples consist of single-phase ...
Electrochemical behavior of esomeprazole: Its determination at Au electrode as standard and in injection powder combined with the study of its degradation
(Elsevier Science Sa, Lausanne, 2019)
Esomeprazole is the most effective of the proton-pump inhibitors for the acid-related diseases and at first was examined for the electroanalytical purposes. The drug standard and as a content of injection powder was ...
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. ...
Electrochemical Oxidation of Bromides on DSA/RuO2 Anode in the Semi-Industrial Batch Reactor for On-Site Water Disinfection
(Electrochemical Soc Inc, Pennington, 2019)
The electrochemical oxidation of bromides for on-site water disinfection, on dimensionally stable DSA titanium coated RuO2 anode is investigated by the polarization measurements and in the semi-industrial batch reactor ...
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, ...
Biomimetic characterization reveals enhancement of hydroxyapatite formation by fluid flow in gellan gum and bioactive glass composite scaffolds
(Elsevier Sci Ltd, Oxford, 2019)
This study presents production and biomimetic characterization of macroporous composite scaffolds based on gellan gum and nanoparticulate bioactive glass (GG-BAG) under conditions relevant for bone tissue engineering. ...
Impact resistant hybrid composites reinforced with inorganic nanoparticles and nanotubes of WS2
(Elsevier Sci Ltd, Oxford, 2019)
Impact resistant nanocomposites are recognized as promising in saving lives in the car, skiing and bicycle accidents, preventing the failure of polymer-based prostheses and orthotic devices, as well as for various defense ...
Influence of different concentrations of Zn-carbonate phase on physical-chemical properties of antimicrobial agar composite films
(Elsevier, Amsterdam, 2019)
Agar-based composites with different Zn-carbonate mineral phase content were prepared by in situ mineralization and the solvent casting method. The mineral phase within the composite films was identified as hydrozincite, ...
Biodegradation of poly(epsilon-caprolactone) (PCL) and medium chain length polyhydroxyalkanoate (mcl-PHA) using whole cells and cell free protein preparations of Pseudomonas and Streptomyces strains grown on waste cooking oil
(Elsevier Sci Ltd, Oxford, 2019)
Petrochemical plastics are generally recalcitrant to microbial degradation and accumulate in the environment. Biodegradable polymers obtained synthetically like poly(epsilon-caprolactone) (PCL) or poly-hydroxyalkanoates ...
