Phenol determination on HDTMA-bentonite-based electrodes
(Elsevier, 2011)
The partial and complete substitution of cations in the interlayer region of clay with different amounts of hexadecyl trimethylammonium bromide (HDTMABr) was performed. The aim was to synthesize organo-bentonites to be ...
Mass spectrometry based proteomics as foodomics tool in research and assurance of food quality and safety
(Elsevier Science London, London, 2018)
Background.: As a comprehensive discipline that studies food and nutrition, foodomics requires reliable qualitative and quantitative information about the food proteome component in order to extract new integrative information ...
Natural and anthropogenic factors affecting the groundwater quality in Serbia
(Elsevier, 2014)
Various chemometric techniques were used to analyze the quality of groundwater data sets. Seventeen water quality parameters: the cations Na, K, Ca, Mg, the anions Cl, SO4, NO3, HCO3 and nine trace elements Pb, As, Mn, Ni, ...
Stacking Interactions between Square-Planar Metal Complexes with 2,2'-Bipyridine Ligands. Analysis of Crystal Structures and Quantum Chemical Calculations
(American Chemical Society (ACS), 2014)
Stacking interactions between square-planar metal complexes containing bipyridine ligands (bipy) were studied by analyzing data in the Cambridge Structural Database (CSD) and by density functional theory (DFT) calculations. ...
Chromium (VI) removal from aqueous solutions using mercaptosilane functionalized sepiolites
(Elsevier, 2011)
Natural and acid-activated sepiolite samples were functionalized with (3-Mercaptopropyl)trimethoxysilane.
By X-ray powder diffraction, Fourier transform infrared spectroscopy, and differential thermal
analysis it was ...
Modification of glassy carbon properties under low energy proton irradiation
(Oxford : Pergamon-Elsevier Science Ltd, 2011)
Glassy carbon plates were irradiated with 15 key H(+) ion-beam in the fluence range of 1 x 10(16)-3 x 10(18) ion cm(-2). The influence of ion irradiation on surface morphology and topology was examined by scanning electron ...
Kinetics of deep oxidation of n-hexane and toluene over Pt/Al2O3 catalysts: Platinum crystallite size effect
(Elsevier, 2004)
The kinetics of n-hexane and toluene complete oxidation has been studied over 0.12% Pt/Al 2 O 3 catalysts. Measurements were performed in an external recycle reactor. Reaction rates were measured as a function of temperature ...
C-H/O Interactions of Aromatic CH Donors within Proteins: A Crystallographic Study
(American Chemical Society (ACS), 2016)
C-H/O interactions of aromatic C-H donors within proteins have been studied by analyzing the data in the Protein Data Bank (PDB). The C-H/O interactions were studied between aromatic donors; phenylalanine, tyrosine, and ...
Engineered surface waves in hyperbolic metamaterials
(Optical Society of America, 2013)
We analyzed surface-wave propagation that takes place at the boundary between a semi-infinite dielectric and a multilayered metamaterial, the latter with indefinite permittivity and cut normally to the layers. Known ...
Anodic luminescence, structural, photoluminescent, and photocatalytic properties of anodic oxide films grown on niobium in phosphoric acid
(Elsevier, 2015)
This article reports on properties of oxide films obtained by anodization of niobium in phosphoric acid before and after the dielectric breakdown. Weak anodic luminescence of barrier oxide films formed during the anodization ...
