Polyurethane reinforced with carbon nanotubes outperforms currently used materials Efforts to build larger wind turbines able to capture more energy from the air are stymied by the weight of blades. A Case Western Reserve University researcher has built a prototype blade that is substantially lighter and eight times tougher and more durable than currently used blade materials. Marcio Loos, a post-doctoral researcher in the Department of Macromolecular Science and Engineering, works with...

DNA, a molecule famous for storing the genetic blueprints for all living things, can do other things as well. In a new paper,* researchers at the National Institute of Standards and Technology (NIST) describe how tailored single strands of DNA can be used to purify the highly desired "armchair" form of carbon nanotubes. Armchair-form single wall carbon nanotubes are needed to make "quantum wires" for low-loss, long distance electricity transmission and wiring. Single-wall carbon nanotubes are...

The Elsevier journal Reinforced Plastics reported that Zyvex Technologies' Piranha, a 54 ft unmanned boat built using carbon nanotube strengthened prepreg, has completed sea trials which demonstrate record fuel efficiency. Piranha is an unmanned surface vessel (USV) designed to enable a broad range of operations at sea with reduced operational costs and risks to sailors. The ground-breaking research that make such advances possible are reviewed in new and forthcoming books from Elsevier's...

Penn researchers have helped develop a nanotech device that combines carbon nanotubes with olfactory receptor proteins, the cell components in the nose that detect odors. Because olfactory receptors belong to a larger class of proteins that are involved in passing signals through the cell membrane, these devices could have applications beyond odor sensing, such as pharmaceutical research.  The research was led by professor A. T. Charlie Johnson, postdoctoral fellow Brett R. Goldsmith...

Terahertz radiation can penetrate numerous materials"”plastic, clothing, paper and some biological tissues"”making it an attractive candidate for applications such as concealed weapons detection, package inspection and imaging skin tumors. However, to date there is no standard method for measuring the absolute output power of terahertz lasers, one source of this type of radiation. Now, researchers at the National Institute of Standards and Technology (NIST) have found that dense...

Nanoengineered graphene coating harvests energy from flowing water, powers microsensors used to detect underground oil and gas Researchers at Rensselaer Polytechnic Institute have developed a new method to harvest energy from flowing water. This discovery aims to hasten the creation of self-powered microsensors for more accurate and cost-efficient oil exploration. Led by Rensselaer Professor Nikhil Koratkar, the researchers investigated how the flow of water over surfaces coated with the...

Advice on the use of carbon nanotubes from a new research study Which is better, a quick vertical jab on the buttock or the delicately soft entry of a blood sample? Waiting to find out "for what", some are already wondering "how" to use those tiny "molecular syringes" which are carbon nanotubes. With a diameter of less than one millionth of a millimeter (nanometer) and a maximum length of just a few millimeters, the first use that springs to mind when we think of this ethereal tubes - the...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
