The carbon nanotubes form a promising tool in the emerging fields of nanotechnology and its reassuring development. The importance lies in the fact that the whole development has been from carbon which forms the basic unit. The future lies in continuous improvement in the required properties of materials by artificially structuring them on nanometer scale and developing processing methods for their manufacture.

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 o..............etc

Photocatalysis is an advanced oxidation process and receiving widespread attention in recent times for completely mineralizing organic contaminants in water and air. As a first part of our study, the parameters (dissolved oxygen, catalyst concentration, and light intensity) influencing intrinsic kinetics of phenol degradation is investigated using immersion-well batch reactor with 6 and 125 W UV-A lamps. At high light intensity, dissolved oxygen concentration in the slurry decides the optimum catalyst loading. At low light intensity comparable ..............etc

The economics of international emissions trading

It's possible for a country to reduce emissions using a Command-Control approach, such as regulation, direct and indirect taxes. But that approach is more costly for some countries than for others. That's because the Marginal Abatement Cost (MAC) ? the cost of eliminating an additional unit of pollution ? differs by country. It might cost China $2 to eliminate a ton of CO2, but it would probably cost Sweden or the U.S. much more. International emissions-trading markets we..............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

The remarkable properties of carbon nanotubes may allow them to play a crucial role in the relentless drive towards miniaturization at the nanometre scale.

Nanotechnology is predicted to spark a series of industrial revolutions in the next two decades that will transform our lives to a far greater extent than silicon microelectronics did in the 20th century. Carbon nanotubes could play a pivotal role in this upcoming revolution if their remarkable electrical and mechanical properties can be exploited.

Since the first measurements were ma..............etc
