Investigation of ultrafast carrier dynamics in curcumin dye for environment friendly dye-sensitized solar cell.

Natural dyes have been widely employed in the fabrication of dye-sensitized solar cells (DSSCs). DSSCs are favored for their cost-effective, and simple fabrication process relies on metal-based and organic dyes. The choice of dyes greatly affects the performance of DSSCs.

Hydrogenation properties and kinetic study of MgH - x wt% AC nanocomposites prepared by ball milling.

The high de-/hydrogenation temperature of magnesium hydride is still a challenge in solid-state hydrogen storage system for automobiles applications. To improve the hydrogenation properties of MgH we select activated carbon/charcoal (AC) as a catalyst. A systematic investigation was performed on the hydrogen storage behaviors of MgH and MgH - 5 wt% AC nanocomposites, which were prepared by a high-energy planetary ball mill.

Catalytic effect on hydrogen de/absorption properties of MgH - x wt% MM (x = 0, 10, 20, 30) nanomaterials.

Reversible hydrogen storage in MgH under specified conditions is a possible way for the positive reception of hydrogen economy, in which the developments of cheap and highly efficient catalysts are the major challenge, still now. Herein, MgH - x wt% MM (x = 0, 10, 20, 30) nanomaterials are prepared via ball milling method and has been evaluated for the hydrogen storage performance, which are characterized by XRD, SEM and DTA/DSC. The hydrogen absorption properties of nanomaterials are measured by pressure composition isotherm, and analysis show that the MgH - 30 wt% MM nanomaterials have the maximum hydrogen absorption capacity (~ 3.

Engineering high-performance Pd core-MgO porous shell nanocatalysts via heterogeneous gas-phase synthesis.

We report on the design and synthesis of high performance catalytic nanoparticles with a robust geometry via magnetron-sputter inert-gas condensation. Sputtering of Pd and Mg from two independent neighbouring targets enabled heterogeneous condensation and growth of nanoparticles with controlled Pd core-MgO porous shell structure. The thickness of the shell and the number of cores within each nanoparticle could be tailored by adjusting the respective sputtering powers.
