Abstract: A vibrator that is capable of vibrating without using an electrode and has good detection sensitivity is provided. A carbon-based material vibrator for vibration by light irradiation has a biological substance or a substance capable of identifying a biological substance immobilized on the vibrator. The vibrator may not include a counter electrode for applying a voltage to the vibrator. The carbon-based material may be graphite. A thermal conductivity λ1 in a plane direction of the carbon-based material is 100 times or more than a thermal conductivity λ2 in a thickness direction of the carbon-based material.

Abstract: The objective of the present invention is to provide a carbon-based hydrogen storage material having an autocatalytic capability and an atomic vacancy, wherein the hydrogen storage is a hydrocarbon compound which produces a non-endothermic release or an exothermic release of hydrogen adsorbed in the compound. In addition, the present invention provides a method of manufacturing the material comprising: preparing a hydrocarbon compound as the raw material of the carbon-based hydrogen storage material; setting the raw material in a container having a predetermined gas partial pressure; producing the hydrocarbon compound by ion beam irradiation of the raw material; performing annealing treatment under the predetermined conditions; and exposing the product to the hydrogen under the predetermined conditions, wherein the product is a hydrogen storage hydrocarbon compound producing a non-endothermic or an exothermic release of hydrogen adsorbed thereto with autocatalysis activity.
