Microstructural characterization of mechanically activated ZnO-Cr2O3 system
(Oxford : Elsevier Sci, 2005)
An equimolar mixtures of starting ZnO and Cr2O3 powders were mechanically activated by grinding using a planetary ball mill for various periods of time (40-320min). Formation of nanocrystalline ZnCr2O4 as normal spine] ...
One-shot Nano-device for Treatment of Peri-implantitis: Biological Proof of Concept
(Madrid : [s.n.], 2019)
Objectives To compare biological effects of experimental nano device composed of nano-hydroxyapatite loaded with clindamycin, embedded in PLGA for continual release of daily MIC against Porphiromonas gingivalis for 21 days ...
Reversible intercalation/deintercalation of lithium ions within γ-LiV2O5 polymorph
(Belgrade : Materials Research Society of Serbia, 2021)
The electrochemical insertion of lithium ions in V2O5 produces various crystal structures depending on lithium concentration. Compositions with lithium content in the range of 1 ≤ x ≤ 1.8 take orthorhombic γ-LixV2O5 form. ...
FES of Upper Extremities: Post-conference course
(Vienna : Medical University of Vienna, 2019)
The workshop is structured to have a theoretical introduction and subsequent application oriented hands-on demonstrations. The workshop is planned to include continuous interactive discussion. The workshop will focus on ...
Microstructure development and Raman responses of mechanically activated Fe/BaTiO3
(Belgrade : Serbian Ceramic Society, 2015)
The structure and lattice dynamics of mechanically activated nanocrystalline Fe/BaTiO3 is investigated in this work. The powder mixture of 60%Fe and 40% BaTiO3 was mechanically activated up to 240 min in 500 cm3 zirconium ...
Hydrogen evolution on Ni/WC composite coatings
(Springer, 2006)
The catalytic activity for the hydrogen evolution reaction (HER) of Ni/WC composites obtained by electrochemicaldeposition of nickel from a conventional Watt’s bath, using two different ways of depositing the WC particles, ...
Influence of prolonged sintering time on density and electrical properties of isothermally sintered cordierite-based ceramics
(Belgrade : International Institute for the Science of Sintering, 2013)
Mechanical activation is a commonly used and relatively fast and inexpensive procedure for sample preparation before the sintering process. Cordierite, a stoichiometric mixture of three different oxides (2MgO⋅2Al2O3⋅5SiO2) ...
An adsorption-based mercury sensor with continuous readout
(Springer-Verlag, 2013)
A novel readout procedure for a mercury sensor has been proposed. The sensor is based on the surface adsorption. Mercury vapor is adsorbed at the surface of a thin gold layer patterned into four meanders which are connected ...
Detection Limit for an Adsorption-Based Mercury Sensor
(Elsevier, 2013)
A novel readout procedure for the determination of detection limit at an adsorption-based mercury sensor is described. The procedure is based on the evaluation of the initial voltage slope in time evolution of adsorbed ...
Synthesis of barium-zinc-titanate ceramics
(Belgrade : International Institute for the Science of Sintering, 2012)
Mixtures of BaCO3, ZnO and TiO2 powders, with molar ratio of 1:2:4, were mechanically activated for 20, 40 and minutes in a planetary ball mill. The resulting powders were compacted into pellets and isothermally sintered ...
