Enhancement of Destabilization and Reactivity of Mg Hydride Embedded in Immiscible Ti Matrix by Addition of Cr: Pd-Free Destabilized Mg Hydride

Nanometer-sized Mg hydride clusters may form in a self-organized way by the hydrogenation of a nonequilibrium Mg-Ti alloy. Here the Mg hydride is destabilized by the interface energy between the two metal hydrides. To obtain an even more destabilized Mg hydride, we increased the interface energy by the addition of Cr, which is immiscible with...

A reliable, sensitive and fast optical fiber hydrogen sensor based on surface plasmon resonance

We report for the first time on the experimental response of a Surface Plasmon Resonance fiber optic sensor based on wavelength modulation for hydrogen sensing. This approach of measuring the hydrogen concentration makes the sensor insensitive to intensity fluctuations. The intrinsic fiber sensor developed provides remote sensing and enables the...

Eye readable metal hydride based hydrogen tape sensor for health applications

Using the change in the intrinsic optical properties of YMg-based thin films upon exposure to hydrogen, we observe the presence of hydrogen at concentrations as low as 20 ppm just by a change in color. The eye-visible color change circumvents the use of any electronics in this device, thereby making it an inexpensive H2 detector. The detector...
