Photo-induced properties of photocatalysts: A study on the modified structural, optical and textural properties of TiO2-ZnAl layered double hydroxide based materials
(Elsevier Sci Ltd, Oxford, 2017)
Heterogeneous photocatalytic oxidation technologies, based on the free-radical reaction initiated by a light irradiation of photocatalyst surface, are promising methods for water and air purification, being one of overwhelming ...
Brachybacterium sp CH-KOV3 isolated from an oil-polluted environment-a new producer of levan
(Elsevier, 2017)
Various microorganisms isolated from polluted environments, such as Pseudomonas sp. and Micrococcus sp. can synthesize exopolysaccharides (EPSs) which are natural, non-toxic and biodegradable polymers. EPSs play a key role ...
Analysis of Tea for Metals by Flame and Graphite Furnace Atomic Absorption Spectrometry with Multivariate Analysis
(Taylor and Francis Inc., 2017)
The concentrations of iron, zinc, manganese, copper, chromium, nickel, lead, arsenic, and cadmium were determined using flame and graphite furnace atomic absorption spectrometry in nine herbal tea samples. Hawthorn, yarrow, ...
Biocompatibility Investigation of New Endodontic Materials Based on Nanosynthesized Calcium Silicates Combined with Different Radiopacifiers
(Elsevier Science Inc, New York, 2017)
Introduction: The aim of this article was to analyze biocompatibility and bioactivity of new endodontic materials on the basis of nanosynthesized calcium silicates (ALBO-MPCA(1) and ALBO-MPCA(2)) combined with different ...
A continuous process for the ultrasonic spray pyrolysis synthesis of RuO2/TiO2 particles and their application as a coating of activated titanium anode
(Elsevier, 2017)
Synthesis and subsequent deposition of sub-micron spherical RuO2/TiO2 particles onto titanium were performed by continuous process in two connected reactors, exclusively applied for this purpose. Synthesis of particles was ...
Application of the general theory of disperse deposits formation in an investigation of mechanism of zinc electrodeposition from the alkaline electrolytes
(Elsevier, 2017)
In this study, mechanism of electrodeposition of zinc from the alkaline electrolytes has been investigated using the general theory of disperse deposits formation. The exchange current densities in the range 18.4-88 mA ...
Organic Rankine Cycle system performance targeting and design for multiple heat sources with simultaneous working fluid selection
(Elsevier Sci Ltd, Oxford, 2017)
This work presents a systematic approach toward the design of Organic Rankine Cycles (ORC) for the generation of power from multiple heat sources available at different temperature levels. The design problem is approached ...
Determination of 200 degrees C Isothermal Section of Al-Ag-Ga Phase Diagram by Microanalysis, X-ray Diffraction, Hardness and Electrical Conductivity Measurements
(Springer, New York, 2017)
Ternary Al-Ag-Ga system at 200 degrees C was experimentally and thermodynamically assessed. Isothermal section was extrapolated using optimized thermodynamic parameters for constitutive binary systems. Microstructure and ...
High Energy/Power Supercapacitor Performances of Intrinsically Ordered Ruthenium Oxide Prepared through Fast Hydrothermal Synthesis
(Wiley-V C H Verlag Gmbh, Weinheim, 2017)
A simple one-step microwave-assisted and temperature-controlled hydrothermal synthesis was applied to prepare a nanocrystalline RuO2 dispersion from an aqueous solution of RuCl3 for supercapacitive applications. The obtained ...
Zinc concentrations in human milk and infant serum during the first six months of lactation
(Elsevier Gmbh, Urban & Fischer Verlag, Jena, 2017)
Normal supply of zinc to the newborn via milk is essential for normal development. Using ICP-OES, we analyzed changes in the level of Zn in milk and infant serum in the neonatal period (Day 1 and Day 28 post partum) and ...
