Mass transfer and concentration boundary layer in a particulate fluidized bed
(Elsevier, 2016)
The aim of this study was to analyze the concentration boundary layer for a comprehensive description of the mass transfer in systems with fluidized particles. Mass transfer from the wall of the column to the fluid in the ...
Effect of Tb3+ doping on the photocatalytic activity of TiO2 coatings formed by plasma electrolytic oxidation of titanium
(Elsevier, 2018)
Tb doped TiO2 coatings are formed by plasma electrolytic oxidation (PEO) of titanium in water solution of 10 g/L Na3PO4.12H(2)O with addition of Tb4O7 powder. Surface morphology, chemical, and phase composition of obtained ...
Wall effects on the velocities of a single sphere settling in a stagnant and counter-current fluid and rising in a co-current fluid
(Elsevier Science Sa, Lausanne, 2010)
Experimental results were obtained on the steady settling of spheres in quiescent media in a range of cylindrical tubes to ascertain the wall effects over a relatively wide range of Reynolds number values. For practical ...
Synthesis and characterization of AgPd alloy coatings as beneficial catalysts for low temperature fuel cells application

Maskless convex corner compensation technique on a (100) silicon substrate in a 25 wt% TMAH water solution
(Iop Publishing Ltd, Bristol, 2012)
A maskless convex corner compensation technique in a 25 wt% TMAH water solution at the temperature of 80 degrees C is presented and analyzed. The maskless convex corner compensation technique is defined as a combination ...
Characterization of PCBs from computers and mobile phones, and the proposal of newly developed materials for substitution of gold, lead and arsenic
(Springer Heidelberg, Heidelberg, 2013)
In this paper, we have analyzed parts of printed circuit board (PCB) and liquid crystal display (LCD) screens of mobile phones and computers, quantitative and qualitative chemical compositions of individual components, and ...
Experimental investigation and thermodynamic prediction of the Bi-Sb-Zn phase diagram
(Elsevier Science Sa, Lausanne, 2010)
Phase diagram of the ternary Bi-Sb-Zn system was investigated experimentally by DTA and SEM-EDS methods and analytically by CALPHAD method. The liquidus projection, invariant equilibria, several vertical sections and ...
Synthesis and characterization of bentonites rich in beidellite with incorporated Al or Al-Fe oxide pillars
(Elsevier, 2013)
Pillared clays (PILCs) based on bentonite clay from "Bogovina" (Serbia) were obtained using Al3+ and Fe3+ pillaring cations in different ratios. Thorough characterization of the starting material and PILCs was performed ...
Trace elements in size-segregated urban aerosol in relation to the anthropogenic emission sources and the resuspension
(Springer Heidelberg, Heidelberg, 2014)
Size segregated particulate samples of atmospheric aerosols in urban site of continental part of Balkans were collected during 6 months in 2008. Six stages impactor in the size ranges: Dp LT = 0.49 mu m, 0.49 LT Dp LT = ...
Butterfly scales as bionic templates for complex ordered nanophotonic materials: A pathway to biomimetic plasmonics
(Elsevier, 2013)
In this paper we propose a possible use of butterfly scales as templates for ordered 2D or 3D nanophotonic materials, with complexity not easily reproducible by conventional micro/nanofabrication methods. Functionalization ...
