Toughening of complete solid solution cermets by graphite addition
(Elsevier, 2015)
(Ti0.95Ta0.05)(C0.5N0.5)-Co complete solid solution cermets (CSCs) were developed by a mechanochemical synthesis process and a pressureless sintering method. The effect of different percentages of graphite used as a sintering ...

Mechanically induced self-propagating reaction of vanadium carbonitride
(Elsevier, 2015)
Vanadium carbonitrides (VCxN1−x) were prepared via mechanosynthesis from mixtures of elemental vanadium and carbon with different V/C atomic ratios under a nitrogen atmosphere using a high-energy ball mill. We obtained the ...

Influence of the milling parameters on the mechanical work intensity in planetary mills
(Elsevier, 2013)
The formation of ZnSe via a mechanically-induced self-sustaining reaction (MSR) from a Zn/Se mixture showed that only size reduction and mixing of the reactants without product formation occurred during the induction period ...

RTD based logic circuits using generalized threshold gates
(2008)
Many logic circuit applications of Resonant Tunneling Diodes are based on the MOnostable-BIstable Logic Element (MOBILE). Threshold logic is a computational model widely used in the design of MOBILE circuits, i.e. these ...

Mechanochemical synthesis of ZrB2-SiC-ZrC nanocomposite powder by metallothermic reduction of zircon
(Elsevier, 2013)
Aluminium and magnesium were used in the M/ZrSiO4/B 2O3/C (M = Al, Mg) system to induce a mechanically induced self-sustaining reaction (MSR). Aluminium was not able to reduce the system to the desired products, and the ...

Exalted photocatalytic activity of tetragonal BiVO4 by Er 3+ doping through a luminescence cooperative mechanism
(Royal Society of Chemistry (Great Britain), 2014)
Er-doped BiVO4 are synthesized by means of a surfactant free microwave assisted hydrothermal method having good photoactivities under sun-like excitation for the degradation of methylene blue. From the structural and ...

Mechanosynthesis of nanocrystalline ZrB2-based powders by mechanically induced self-sustaining reaction method
(Elsevier, 2013)
Preparation of nanocrystalline ZrB2-based powder by aluminothermic and magnesiothermic reductions in M/ZrO2/B 2O3 (M = Al or Mg) systems was investigated. In this research, high energy ball milling was employed to persuade ...

Kinetics of high-temperature oxidation of (Ti,Ta)(CN)-based cermets
(Elsevier, 2016)
The kinetics of the high-temperature oxidation of titanium–tantalum carbonitride-based cermets with different Ti/Ta ratios was studied. Isothermal oxidation tests were conducted under static air for 48 h at temperatures ...

Room temperature mechanosynthesis of the La 1-xSr xMnO 3±δ (0≤x≤1) system and microstructural study
(Elsevier, 2012)
Monophase nanocrystalline powders belonging to the La 1-xSr xMnO 3±δ system (0≤x≤1) with a perovskite structure have been obtained by mechanochemistry synthesis using a planetary ball milling equipment from La 2O 3, SrO, ...

Support Effects on NiO-based Catalysts for the Oxidative Dehydrogenation (ODH) of Ethane
(Elsevier, 2019)
We report on the effect of NiO-support interactions on the chemical nature of Ni species in a series of supported NiO catalysts for the ODH of ethane. SiO2, TiO2-anatase, a high surface area TiO2 and a porous clay ...
