Latest Carbon nanotube Stories
Nanotechnology refers to a broad range of tools, techniques and applications that simply involve particles on the approximate size scale of a few to hundreds of nanometers in diameter. Particles of this size have some unique physicochemical and surface properties that lend themselves to novel uses. Indeed, advocates of nanotechnology suggest that this area of research could contribute to solutions for some of the major problems we face on the global scale such as ensuring a supply of safe...
Researchers have shown that an advanced cooling technology being developed for high-power electronics in military and automotive systems is capable of handling roughly 10 times the heat generated by conventional computer chips.The miniature, lightweight device uses tiny copper spheres and carbon nanotubes to passively wick a coolant toward hot electronics, said Suresh V. Garimella, the R. Eugene and Susie E. Goodson Distinguished Professor of Mechanical Engineering at Purdue University.This...
A flexible, printable material 4-or-fewer-atoms-thick may be a high road to economical and convenient electrical power from the sunA University of Southern California team has produced flexible transparent carbon atom films that the researchers say have great potential for a new breed of solar cells."Organic photovoltaic (OPV) cells have been proposed as a means to achieve low cost energy due to their ease of manufacture, light weight, and compatibility with flexible substrates,"...
Materials for tomorrow's nanoelectronicsIn the recent issue of Nature, scientists from Empa and the Max Planck Institute for Polymer Research report how they have managed for the first time to grow graphene ribbons that are just a few nanometers wide using a simple surface-based chemical method. Graphene ribbons are considered to be «hot candidates» for future electronics applications as their properties can be adjusted through width and edge shape.Transistors on the basis of graphene...
A group of researchers from Wake Forest University Baptist Medical Center is developing a way to treat cancer by using lasers to light up tiny nanoparticles and destroy tumors with the ensuing heat.Today at the 52nd Annual Meeting of the American Association of Physicists in Medicine (AAPM) in Philadelphia, they will describe the latest development for this technology: iron-containing Multi-Walled Carbon Nanotubes (MWCNTs) -- threads of hollow carbon that are 10 thousand times thinner than a...
HOUSTON, July 20 /PRNewswire/ -- NanoRidge Materials, Inc., a Houston based nanotechnology manufacturing company has partnered with Riley Solutions, Inc. to manufacture and supply specialized nanotechnology enhanced armor for the Department of Defense. As part of the partnership, Riley Solutions, Inc. is moving their headquarters from North Carolina to Houston, Texas, resulting in NanoRidge Materials, Inc. expanding into a 55,000 sq. ft. facility in the Houston area and creating 300 new...
Rice researchers' method untangles long tubes, clears hurdle toward armchair quantum wireRice University scientists have found the "ultimate" solvent for all kinds of carbon nanotubes (CNTs), a breakthrough that brings the creation of a highly conductive quantum nanowire ever closer.Nanotubes have the frustrating habit of bundling, making them less useful than when they're separated in a solution. Rice scientists led by Matteo Pasquali, a professor in chemical and biomolecular...
Metallic carbon nanotubes show great promise for applications from microelectronics to power lines because of their ballistic transmission of electrons. But who knew magnets could stop those electrons in their tracks?Rice physicist Junichiro Kono and his team have been studying the Aharonov-Bohm effect -- the interaction between electrically charged particles and magnetic fields -- and how it relates to carbon nanotubes. While doing so, they came to the unexpected conclusion that magnetic...
Since its discovery, graphene"”an unusual and versatile substance composed of a single-layer crystal lattice of carbon atoms"”has caused much excitement in the scientific community. Now, Nongjian (NJ) Tao, a researcher at the Biodesign Institute at Arizona State University has hit on a new way of making graphene, maximizing the material's enormous potential, particularly for use in high-speed electronic devices.Along with collaborators from Germany's Max Planck Institute, the Department...
A cluster of carbon nanotubes coated with a thin layer of protein-recognizing polymer form a biosensor capable of using electrochemical signals to detect minute amounts of proteins, which could provide a crucial new diagnostic tool for the detection of a range of illnesses, a team of Boston College researchers report in the journal Nature Nanotechnology.The nanotube biosensor proved capable of detecting human ferritin, the primary iron-storing protein of cells, and E7 oncoprotein derived from...
