The kinetics of hydrogen absorption/desorption can be improved by decreasing particle size down to a few nanometres. However, the associated evolution of activation energy remains unclear. In an attempt to clarify such an evolution with respect to particle size, we electrochemically deposited Mg nanoparticles on a catalytic nickel and noncatalytic titanium substrate. At a short deposition time ...

This study describes the application of novel chemistry methods for the removal of dye by Nano structured titanium oxide (TiO2) photo catalysts. Such materials can be applied in the development of efficient photo catalytic systems for the treatment of water. Nano crystalline TiO2 was synthesized by Sol-Gel route using titanium tetraisopropoxide as a metal precursor. The catalysts were character...

It is well known that semi-solid forming could only obtain coarse-grained microstructure in a few alloy systems with a low melting point, such as aluminum and magnesium alloys. This work presents that semi-solid forming could also produce novel bimodal microstructure composed of nanostructured matrix and micro-sized (CoFe)Ti2 twins in a titanium alloy, Ti62Nb12.2Fe13.6Co6.4Al5.8. The semi-solid...

This paper reports the synthesis of high molecular weight semi-aromatic polyamides containing renewable furanic monomer by a scalable melt polycondensation method using eco-friendly titanium-based catalysts.

A previous study showed that BMP-2 (bone morphogenetic protein-2) and wear debris can separately support osteoclast formation induced by the receptor activator of NF-κB ligand (RANKL). However, the effect of BMP-2 on wear debris-induced osteoclast formation is unclear. In this study, we show that neither titanium particles nor BMP-2 can induce osteoclast formation in RAW 264.7 mouse leukemic mo...

Ordering of disordered materials occurs during the activated process of nucleation that requires the formation of critical clusters that have to surmount a thermodynamic barrier. The characterization of these clusters is experimentally challenging but mandatory to improve nucleation theory. In this paper, the nucleation of a magnesium alumino-silicate glass containing the nucleating oxide TiO(2...

Nanosized titanium particles have attracted extensive research interest because of their diverse applications in, for instance, catalysis, energy conversion, and biomedical engineering. Of these, titanium colloids have been used as effective catalysts for the hydrogenation of titanium and zirconium sponses and as a powerful activator for heterogeneous hydrogenation catalysts. Titanium nanoparti...
