Disclosed is a method of: providing a hydrogenated spcarbon allotrope, and releasing hydrogen gas from the carbon allotrope. The method may use an apparatus having: a vessel for containing the hydrogenated spcarbon allotrope, a fuel cell capable of using hydrogen gas a fuel, and a tube for transporting hydrogen gas from the vessel to the fuel cell. The carbon allotrope may be made by: providing a mixture of an spcarbon allotrope and liquid ammonia, adding an alkali metal to the mixture, and sonicating the mixture to form a hydrogenated form of the carbon allotrope. The hydrogenated carbon can be at least 3.5 wt % hydrogen covalently bound to the carbon.

CMOS integrated micromechanical resonators and methods for fabricating the same

A method for manufacturing or preparing thin-film stacks that exhibit moderate, finite, stress-dependent resistance and which can be incorporated into a transduction mechanism that enables simple, effective signal to be read out from a micro- or nano-mechanical structure. As the structure is driven, the resistance of the intermediate layers is modulated in tandem with the motion, and with suitable dc-bias, the motion is directly converted into detectable voltage. In general, detecting signal from MEMS or NEMS devices is difficult, especially using a method that is able to be integrated with standard electronics. The thin-film manufacturing or preparation technique described herein is therefore a technical advance in the field of MEMS/NEMS that could enable new applications as well as the ability to easily develop CMOS-MEMS integrated fabrication techniques. Also disclosed are: (i) transducers where current flows across a piezo layer from one major surface to the opposite major surface; and (ii) methods of making a transducer the resistivity of a piezoresistive layer is decreased and/or the gauge factor of a piezoresistive layer is increased.
