Improving dispersion of SnO2 nanoparticles in Ag-SnO2 electrical contact materials using template method
(Elsevier, 2013)
Considering that improvement in the performance of Ag-SnO2 electrical contact materials can be realized by an increase in metal oxide dispersion, the influence of SnO2 nanoparticles and method of their introduction in ...
Experimental investigation and thermodynamic calculations of the Cu-In-Ni phase diagram
(Elsevier, 2014)
Phase diagram of the Cu-In-Ni ternary system was investigated using differential thermal analysis (DTA), scanning electron microscopy (SEM) with energy dispersive spectrometry (EDS), and X-ray powder diffraction (XRD) ...
Experimental investigation and thermodynamic calculations of the Ag-Bi-Ga phase diagram
(Elsevier, 2015)
Phase diagram of the Ag-Bi-Ga ternary system was investigated using differential thermal analysis (DTA), scanning electron microscopy (SEM) with energy dispersive spectrometry (EDS), and x-ray powder diffraction (XRD) ...
Experimental investigation and thermodynamic calculations of the Al-Cu-Sb phase diagram
(Elsevier, 2013)
Phase diagram of the Al-Cu-Sb ternary system was investigated experimentally by DTA and SEM-EDS methods and theoretically by CALPHAD method. The liquidus projection, invariant equilibria, three vertical sections: Sb-Al0.5Cu0.5, ...
Assessment of the contamination of riparian soil and vegetation by trace metals - A Danube River case study
(Elsevier, 2016)
The aim of this study was to assess the spatial distribution of arsenic and heavy metals (Cd, Cr, Cu Hg, Ni, Pb and Zn) in a riparian area influenced by periodical flooding along a considerable stretch of the Danube River. ...
Influence of annealing temperature on structural, optical and photocatalytic properties of TiO2-CeO2 nanopowders
(Elsevier Sci Ltd, Oxford, 2019)
TiO2-CeO2 nanopowders were synthesised by a ball-milling process and then annealed at temperatures from 500 degrees to 800 degrees C. X-ray diffraction and diffuse reflectance spectra were used in combination with temperature ...
Heat transfer between a packed bed and a larger immersed spherical particle
(Oxford : Pergamon-Elsevier Science Ltd, 2014)
In this paper, heat transfer coefficients between the hot packed beds of particles and the larger cold immersed sphere were experimentally determined. The packed beds consisted of mono-sized spherical glass particles of ...
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 ...
Efficient removal of priority, hazardous priority and emerging pollutants with Prunus armeniaca functionalized biochar from aqueous wastes: Experimental optimization and modeling
(Elsevier, 2018)
This paper investigates the ability of the phosphoric acid functionalized Prunus armeniaca stones biochar (AsPhA) prepared by thermochemical activation to remove lead (Pb2+), cadmium (Cd2+), nickel (Ni2+), naproxen and ...
Anion-pi interactions in active centers of superoxide dismutases
(Elsevier, 2018)
We investigated 1060 possible anion-pi interactions in a data set of 41 superoxide dismutase active centers. Our observations indicate that majority of the aromatic residues are capable to form anion-pi interactions, mainly ...
