Preparation of boron-doped hydrothermal carbon from glucose for carbon paste electrode
(Carbon, 2015)
Boron doped hydrothermal carbon microspheres were synthesized by introducing boric acid into glucose precursor solution to obtain boron concentration from 0.1 to 1 wt. %. Following hydrothermal treatment, samples were ...
Ouzo effect-New simple nanoemulsion method for synthesis of strontium hydroxyapatite nanospheres
(Elsevier, 2016)
Nanoemulsion technique was applied for synthesis of carbonated strontium hydroxyapatite (CSrHAp) at room temperature. X-ray powder diffraction analysis accompanied with Rietveld refinement reviled that synthesized powder ...
The iron(III)-modified natural zeolitic tuff as an adsorbent and carrier for selenium oxyanions
(Microporous and Mesoporous Materials, 2014)
Se(IV) and Se(VI) anions are the dominant species of Se existing in aqueous systems. In this study, the iron(III)-modified natural zeolitic tuff (Fe-CLI) from the Serbian deposit Zlatokop has been investigated as an adsorbent ...
Evolution of the local structure at Hf sites in SiHfOC upon ceramization of a hafnium-alkoxide-modified polysilsesquioxane: A perturbed angular correlation study
(Journal of the European Ceramic Society, 2015)
The evolution of the environment of Hf sites in a hafnium-alkoxide-modified polysilsesquioxane upon polymer-to-ceramic transformation was investigated via the perturbed angular correlation (PAC) method. The results of the ...
Methanol oxidation on Pd/Pt(poly) in alkaline solution
(Journal of Power Sources, 2015)
Bimetallic electrodes prepared by Pd nanoislands spontaneously deposited on polycrystalline platinum, Pt(poly), at submonolayer coverage were explored for methanol oxidation in alkaline media. Characterization of obtained ...
Sintering and electrical properties of Ce1-xBixO2-delta solid solution
(Journal of Alloys and Compounds, 2014)
Solid solution Ce1-xBixO2-delta nanopowders with the composition of x = 0.1-0.5 were synthesized by using Self Propagating Room Temperature procedure (SPRT). The results obtained by XRPD show that synthesized samples were ...
Self-organization in a dissipative three-wave interaction
(Physical Review E, 1999)
A nonlinear three-wave interaction in an open dissipative plasma model of a stimulated Raman backscattering is studied. An anomalous kinetic dissipation due to electron trapping and plasma wave breaking is accounted for ...
Effect of dispersed phase viscosity on maximum droplet generation frequency in microchannel emulsification using asymmetric straight-through channels
(Microfluidics and Nanofluidics, 2011)
Uniformly sized droplets of soybean oil, MCT (medium-chain fatty acid triglyceride) oil and n-tetradecane with a Sauter mean diameter of d (3,2) = 26-35 mu m and a distribution span of 0.21-0.25 have been produced at high ...
Spontaneously Deposited Rh on Au(111) Observed by AFM and XPS: Electrocatalysis of Hydrogen Evolution
(Journal of the Electrochemical Society, 2016)
Rhodium nanoislands were spontaneously deposited on Au(111) up to a full coverage. Obtained Rh/Au(111) bimetallic surface was characterized ex situ by Atomic Force Microscopy imaging and by X-Ray Photoelectron Microscopy, ...
Structural investigation of mechanically activated ZnO powder
(Journal of Alloys and Compounds, 2015)
Commercially available ZnO powder was mechanically activated in a planetary ball mill. In order to investigate the specific surface area, pore volume and microstructure of non-activated and mechanically activated ZnO powders ...
