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.

Hydrogen storage material

An article having: an elastomeric jacket; a gel within the jacket; and a plurality of gas-filled, polymerically-encapsulated microbubbles suspended in the gel. The microbubbles have a Gaussian particle size distribution. The largest microbubble has a diameter at least 10 times the diameter of the smallest microbubble. The article may exhibit Anderson localization at at least one frequency of sound waves impacting the article.

Soft matter having an Anderson transition to a localized phase

A high-sensitivity and ultra-low power consumption magnetic sensor using a magnetoelectric (ME) composite comprising of magnetostrictive and piezoelectric layers. This sensor exploits the magnetically driven resonance shift of a free-standing magnetoelectric micro-beam resonator. Also disclosed is the related method for making the magnetic sensor.

Ultra-low power magnetoelectric magnetic field sensor

A graphene compound made from the method of preparing graphene flakes or chemical vapor deposition grown graphene films on a SiO/Si substrate; exposing the graphene flakes or the chemical vapor deposition grown graphene film to hydrogen plasma; performing hydrogenation of the graphene; wherein the hydrogenated graphene has a majority carrier type; creating a bandgap from the hydrogenation of the graphene; applying an electric field to the hydrogenated graphene; and tuning the bandgap.

Hydrogenated graphene with surface doping and bandgap tunability

A method of introducing a bandgap in single layer graphite on a SiOsubstrate comprising the steps of preparing graphene flakes and CVD grown graphene films on a SiO/Si substrate and performing hydrogenation of the graphene. Additionally, controlling the majority carrier type via surface adsorbates.
