The use of dual metal hydride system for thermal energy storage consists high and low-temperature hydrides. In this study, a 3D cylindrical Magnesium Nickel bed is analyzed discharge. discharge from initially at temperature 400 K, heat transfer fluid 500 K supplied to extract the generated due exothermic chemical reaction. article, variation number tubes effect aspect ratio (ratio diameter heig...

Photodissociation of cold magnesium hydride ions MgH(+) leading to either Mg(+)+H or Mg+H(+) is simulated from first principles. The purpose is to study the possibility of single molecule control of the products in the presence of two laser fields. The system evolves on four electronic potential-energy curves, X(1) Sigma, A(1) Sigma, B(1) Pi, and C(1) Sigma. These potential-energy curves are ca...

A magnesium hydride composite with enhanced hydrogen desorption kinetics can be synthesized via a simple wet chemical route by ball milling MgH2 with LiCl as an additive at room temperature followed by tetrahydrofuran (THF) treatment under an Ar atmosphere. The as-synthesized composite comprises ca. 18 mass% orthorhombic γ-MgH2 and 80 mass% tetragonal β-MgH2 as submicron-sized particles. The β-...
