Development of the Carbon Fiber Reinforced Carbon-carbon Composite for High Temperature Gas-cooled Reactors
In the present paper. details of the development of the candidate CIC composite are described. In the material development, especially, feasibility of the production. stableness of the supply and cost are much taken into consideration. As the physical properties of the material, high mechanical strength such as tensile and bending, high fracture strain and fracture toughness and low dimensional change by neutron ir ....etc

Carbon Nanotube Flow Sensors

Direct generation of measurable voltages and currents is possible when a fluids flows over a variety of solids even at the modest speed of a few meters per second. In case of gases underlying mechanism is an interesting interplay of Bernoulli's principle and the See beck effect: Pressure differences along streamlines give rise to temperature differences across the sample; these in turn produce the measured voltage. The electrical signal is quadratically dependent on the Mach number M and pro ....etc

carbon nanotube antenna in the sub terahertz range ppt

Abstract

In this paper, a new antenna configuration is proposed to operate efficiently in the sub-terahertz frequency range (10-1000 GHz). The proposed antenna is composed of a bundle of single-walled carbon nanotubes (SWCNTs) surrounded by two dielectric jackets; the inner of which is dielectric foam with relative permittivity close to unity. The outer one is a metamaterial layer with permittivity much smaller than the free-space permittivity. Rigorous analysis shows that the metamateria ....etc
