Abstract.
Accordingly, fixation of the CO2 and options for its recycling to useful materials are of prime interest nowadays.
Accordingly, designing of highly efficient catalyst is the key for hydrogenation of low reactive CO2 to methanol synthesis.
Using of ordered mesoporous material as support for the hydrogenation of CO2 to methanol was only recently accessed.
The calcined materials were characterized by N2-adsorption, HRTEM and TPD/R/O.

Abstract.
Magnesium is regarded as a possible hydrogen storage material due to its high hydrogen storage capacity (magnesium hydride corresponds to 7.6 wt.% hydrogen) and low cost. [5,6,7].
However, One key blockade to prevent Mg from practical application in hydrogen storage is its slow hydrogenation kinetics and high dehydrogenation temperature [8].
Contrasting with Ti doping, a Pd dopant will result in a very small activation barrier for dissociation of molecular hydrogen diffusion of atomic H on the Mg surface. the computational finding supports the proposed hydrogen spillover mechanism for rationalizing experimentally observed fast hydrogenation kinetics for Pd-capped Mg materials.
Hydrogen sorption in mechanically alloyed nanocrystalline and disordered materials.

Introduction Shape memory alloys (SMAs) with applications in various fields, such as medical guidewires, cellar-phones antennas, and smart actuators, are also potential candidates for actuators such as motors and supersonic oscillators, because of the extremely large strain and stress generated by the shape memory effect (SME) as compared to those generated in piezoelectric and magnetostrictive materials.
