Progress achieved towards mass producing carbon

CNTs are sheets of carbon that have been rolled into tubes, measuring 100,000 times smaller than the diameter of human hair. Their exceptional electrical, chemical, thermal and mechanical properties make them an ideal material for countless applications, including in

Carbon—The Wonder Element

Carbon is formed by the fusion of three helium nuclei, which scientists believe occurs inside stars called red giants. For the helium to combine, however, certain conditions must be exactly right."Change just a few of the settings [of physical laws] even an infinitesimal

CCOHS: Health and Safety Report

Most carbon nanotubes are made from sheets of graphite about a nanometre, or one billionth of a metre wide, and formed into cylinders. Nanotubes are important in electrical research and the next-generation of computer chips and are also being developed for use in new drugs, batteries and other products.

Quantum effects on adsorption isotherm of hydrogen

UCR Newsroom: Atomic Billiards, Anyone?

September 14, 2007: UC Riverside research shows graphene, a thin sheet of carbon atoms, has good potential to supplement or replace silicon as an electronic material The University of California, Riverside () is a doctoral research university, a living laboratory for groundbreaking exploration of issues critical to Inland Southern California, the state and communities around the world.

Since it was first isolated in 2004 via simple mechanical exfoliation of graphite, graphene has attracted significant attention due to its unique combination of extraordinary electronic, optical, and mechanical properties. Graphene sheets are two-dimensional, one-atom

Exploring Nanotechnology: Fold, Roll, Stack Your Way

Nanotubes are like a single layer of graphite rolled in a cylindrical tube. The buckyball or Buckminsterfullerene looks more or less like a soccer ball. Figure 3, below, shows both. Of course, all these visualizations are not true to size; a buckyball is only a few

Graphite Tubes and Nanotubes The typical mode of thought for graphite tubes typically consists of tubing formed from machined graphite that may be used for furnace and heating applications. Graphite tubes are often chosen over other tubing materials because of their superior thermal conductivity, durability, strength and ability to maintain shape and structure.

Fuel cell

A fuel cell is a device that converts the chemical energy from a fuel into electricity through a chemical reaction with oxygen or another oxidizing agent.1 Hydrogen is the most common fuel, but hydrocarbons such as natural gas and alcohols like methanol are sometimes used. Fuel cells are different from batteries in that they require a constant source of fuel and oxygen to run, but they can

Imaging tool may aid nanoelectronics by screening tiny tubes

Single-wall nanotubes are formed by rolling up a one-atom-thick layer of graphite called graphene, which could eventually rival silicon as a basis for computer chips. Researchers in Cheng's group, working with nanomaterials for biomedical studies, were puzzled when they noticed the metallic nanoparticles and semiconducting nanowires transmitted and absorbed light differently after being

Micro

Carbon nanotubes (CNTs) are relatively new materials with exceptional properties which have attracted significant interest in the past two decades. The ability to grow arrays of vertically aligned carbon nanotubes, so called CNT forest, opened up opportunities to develop different types of novel devices enabled by the material.

Selected topics on the synthesis, properties and

Carbon nanotubes (CNTs) have an astounding array of properties that make them interesting candidates for numerous applications. The geometric and chemical variations found in CNTs provide a rich area of study for both science and applications [1] and [2]. These variations are created by the unique bonding configurations of carbon that make it a ubiquitous part of our environment.

The photoanode can comprise TiO 2 nanowires or nanotubes, and can also include WO 3 nanowires or nanotubes, quantum dots of CdS or PbS, and Ag or Au nanostructures. The cathode can comprise a conductive gas diffusion layer with nanostructures of an electro-catalyst such as Cu or Co.

Researchers develop third and final 'made

(National Institutes of Natural Sciences) The typical 'top-down' method of producing carbon nanotubes does not allow for control over their diameter, length or which of three types will be produced. Control over two types has recently been demonstrated by

UC Irvine Scientists Develop World's Longest Electrically

Breakthrough Discovery Is 10 Times Longer Than Previous Current-Carrying Nanotubes, Paves Way For Supercomputer And Health Care Applications Irvine, Calif., Oct. 18, 2004 - UC Irvine today announced that scientists at The Henry i School of Engineering have synthesized the world's longest electrically conducting nanotubes.

Frontiers

More recently, nanofluids containing carbon nanotubes (CNT) and SiC were produced (Choi, 1995; Choi and Eastman, 2001; Choi et al., 2001; Xie et al., 2003). Tests show that these new nanomaterials have the capability to become the high thermal conductivity nanofluid materials of the future.

What Are Carbon Nanotubes and Why Should You Care?

Carbon nanotubes are made from a graphite-like compound – hence "carbon," in the name. The same material that makes items from coal, to pencil 'lead', to diamonds, can be altered to create a tubular, chicken wire-like sheet of nanoparticles. The nanotube part
