Introduction
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 proportional to the Seebeck coefficient of ....etc

Abstract

We found that very thin carbon nanotube films, once fed by sound frequency electric currents, could emit loud sounds. This phenomenon
could be attributed to a thermoacoustic effect. The ultra small heat capacity per unit area of carbon nanotube thin films leads to a wide
frequency response range and a high sound pressure level. On the basis of this finding, we made practical ....etc

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 ....etc

Memory (NRAM) topic?....please it is urgent....
the abstract for topic is:
Abstract—A 4Mbit nonvolatile memory with a Carbon
Nanotube (CNT) storage element has been manufactured in a
0.25 μm CMOS process at a production fab. The CNT storage
element is integrated in BEOL, requires minimal additional
processing steps, and only a single additional mask. The memory
can be RESET in 50 nanoseconds and SET in 500 nanoseconds. ....etc
