摘要:
A power generating apparatus includes a proton conductor unit, containing a fullerene derivative, a hydrogen electrode bonded to one surface of the proton conductor unit, an oxygen electrode bonded to the other surface of the proton conductor unit, and a hydrogen gas supplying unit for supplying a hydrogen gas at a pressure of approximately 0.2 to approximately 3.5 atm to the hydrogen electrode. The present power generating apparatus effectively suppresses transmission of hydrogen and oxygen gases so that it is possible to prevent the hydrogen gas from being emitted to atmosphere due to transmission as well as to prevent the oxygen gas from reaching the hydrogen electrode on transmission to prevent the hydrogen gas from being consumed without contributing to power generation.

A microelectronic device and a method for producing the device can overcome the disadvantages of known electronic devices composed of carbon molecules, and can deliver performance superior to the known devices. An insulated-gate field-effect transistor includes a multi-walled carbon nanotube (10) having an outer semiconductive carbon nanotube layer (1) and an inner metallic carbon nanotube layer (2) that is partially covered by the outer semiconductive carbon nanotube layer (1). A metal source electrode (3) and a metal drain electrode (5) are brought into contact with both ends of the semiconductive carbon nanotube layer (1) while a metal gate electrode (4) is brought into contact with the metallic carbon nanotube layer (2). The space between the semiconductive carbon nanotube layer (1) and the metallic carbon nanotube layer (2) is used as a gate insulating layer. Two layers including the outer semiconductive carbon nanotube layer (1) and the inner metallic carbon nanotube layer (2) are selected from carbon nanotube layers of a multi-walled carbon nanotube. These layers are processed into a form suitable for use as the multi-walled carbon nanotube (10).

摘要:
There is provided a method for producing a field effect semiconductor device, e.g., a field effect transistor 6 using carbon nanotubes in a channel layer 5, wherein the method includes the step of subjecting the carbon nanotubes to plasma treatment to change a physical or chemical state of the carbon nanotubes. Thus, there can be provided a method which is advantageous in that the method easily produces a field effect semiconductor device which has a current path, e.g., a channel layer, having carbon nanotubes uniformly dispersed therein, and which is prevented from suffering deterioration of the device characteristics due to the formation of bundles of carbon nanotubes.

A hydrogen-storing carbonaceous material is provided. The hydrogen-storing carbonaceous material is obtained by heating a carbonaceous material at lower than about 800° C. before hydrogen is stored under the pressure of hydrogen of about 50 atmospheric pressure or higher. The present invention also provides hydrogen-stored carbonaceous material that is obtained by hydrogen storage in the hydrogen-storing carbonaceous material under the pressure of hydrogen of about 50 atmospheric pressure or higher. This hydrogen-stored carbonaceous material is used for a battery or a fuel cell. The hydrogen-stored carbonaceous material is heated at lower than about 800° C. before the hydrogen is stored under the pressure of hydrogen of about 50 atmospheric pressure or higher, so that the hydrogen-storing carbonaceous material whose hydrogen storage capacity is greatly enhanced can be produced.
