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, ...
Nickel Catalysts on Porous Ceramic Supports for the Reaction of Partial Oxidation of Propane to CO and H2
(Atlantis PressParis: Atlantis Press, 2017)
In this paper synthesis, textural and structural properties as well as selectivity of Ni based catalysts for partial oxidation of propane to CO and H2 are given. The influence of aluminosilicate and magnesia based porous ...
Functionalized biogenic hydroxyapatite with 5-aminosalicylic acid - Sorbent for efficient separation of Pb2+ and Cu2+ ions
(Elsevier, 2017)
The biogenic hydroxyapatite (BHAP), obtained by proper treatment of bovine bones, was functionalized with 5-aminosalicylic acid (5-ASA). The coordination of 5-ASA to the surface of BHAP leads to the charge transfer (CT) ...
Synthesis, Characterization, and Antimicrobial Activity of Silver Nanoparticles on Poly(GMA-co-EGDMA) Polymer Support
(Wiley, Hoboken, 2017)
Poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) (poly(GMA-co-EGDMA) macroporous copolymer decorated with silver nanoparticles was prepared by a modification of poly(GMA-co-EGDMA) in the reaction with arginine, ...
The influence of oxo-bridged binuclear gold(III) complexes on Na/K-ATPase activity: a joint experimental and theoretical approach
(Springer, New York, 2017)
The in vitro effects of oxo-bridged binuclear gold(III) complexes, i.e., [(bipy2Me)(2)Au-2(mu-O)(2)][PF6](2) (Auoxo6), Au-2[(bipydmb-H)(2)(mu-O)][PF6] (Au(2)bipyC) and [Au-2(phen(2Me))(2)(mu-O)(2)](PF6)(2) (Au(2)phen) on ...
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 ...
Estimation of the exchange current density and comparative analysis of morphology of electrochemically produced lead and zinc deposits
(Serbian Chemical Society, 2017)
The processes of lead and zinc electrodeposition from the very dilute electrolytes were compared by the analysis of polarization characteristics and by the scanning electron microscopic (SEM) analysis of the morphology of ...
Electrocoagulation of textile wastewater containing a mixture of organic dyes by iron electrode
(International Association of Physical Chemists (IAPC), 2017)
This study focused on testing the efficacy of iron (Fe) electrode in an electrochemical treatment (electrocoagulation) of wastewater containing a mixture of organic dyes. The mixture consists of the following azo dyes: ...
Vertical accuracy of data on the topographic maps and their application in mining
(Institut za rudarstvo i metalurgiju Bor, 2017)
The paper describes some experiences and the methodology used for evaluation the vertical accuracy of data on the official (state) topographic maps. The vertical accuracy is an important element of quality 3D representation ...
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 ...
