VIBRATION STRENGTH CALCULATED FOR METAL CONSTRUCTIONS

Calculated electronic profiles for liquid-metal surfaces.

Strength training effects of whole-body vibration?

Whole-body vibration (WBV) has been suggested to have a beneficial effect on muscle strength. Manufacturers of vibration platforms promote WBV as an effective alternative or complement to resistance training. This study aimed to review systematically the current (August 2005) scientific support for effects of WBV on muscle strength and jump performance. MEDLINE and SPORT DISCUS were searched fo...

Coherent acoustic vibration of metal nanoshells.

Using time-resolved pump-probe spectroscopy, we have performed the first investigation of the vibrational modes of gold nanoshells. The fundamental isotropic mode launched by a femtosecond pump pulse manifests itself in a pronounced time-domain modulation of the differential transmission probed at the frequency of nanoshell surface plasmon resonance. The modulation amplitude is significantly st...

Ionic adsorbate structures on metal electrodes calculated from first principles

1 The equilibrium coverage of metal electrodes in contact with an electrolyte has been addressed by periodic quantum-chemical calculations based density functional theory. The electrolyte has been treated in a grand-canonical approach using the concept of the computational hydrogen electrode. After briefly reviewing the theory and illustrating it using the co-adsorption of bromide and hydrogen ...

Comparison of metal additives and Boron atom on MgH2 absorbing-desorbing characteristics using calculated NQCCs

Using ab initio calculations, the hydrogen desorption from Magnesium hydride (MgH2) was studied. We presented the calculated nuclear quadrupole coupling constants (NQCCs) of hydrogen atom in various systems of MgH2. The effect of interactions of some metal atoms as well as Boron atom with MgH2 host matrix; (MgH2+M) nanostructures (M=Al, Ti, V, Fe, Ni ...
