Harvesting solar energy is a clever way to make use of a clean and renewable fuel. You don't need to dig the ground for it, there are no pipes and powerplants, and best of all, it's ecological. Unfortunately, existent solar cells are not too efficient and often too expensive.A new development made by resea... |

Carbon nanotubes, though a relatively recent find, have fueled the imagination of many scientists, who strongly believe that they are the future of electronic circuitry and so, the successors of silicon, who by now has almost reached the limit of its applications.Computing industry is not the only field where these... |

Hydrogen-powered cars seem to be the best solution to the problem of fossil fuels pollution. The ever increasing concerns about global warming and the future shortage of natural fuel sources have given the automotive industry and researchers from other fields alike a new impulse in developing new technologies.Hydrog... |

For the past decade, carbon nanotubes, though a relatively recent find, were considered to be the best candidate for replacing silicon in the competition for miniaturization of the computer industry, who by now has almost reached the limit of its applications.Intel, the giant of microprocessors, wants to use these n... |

Computex 2007 is over. But unlike any other computer show (perhaps excepting Cebit), Computex has a way of generating even more questions than answers. And if this phrase sounded a little too cryptic, let me make up for that by saying that a lot of new stuff is being showcased during Computex. Starting with 2000W PSU... |

A new and improved material can produce sensors used in explosives detection. The fluorescent sensor could find practical applications in new devices built for rapid detection of explosives in security screening, criminal investigations, and other applications. Southern Illinois University's Ling Zang and colle... |

Nanotubes have been studied for some time, and there is a great interest in applying their incredible properties in practical applications. They are one-atom thick sheets of graphite (called graphene) rolled up into seamless cylinders with a diameter of the order of a nanometer. A company in the US presented a revol... |

Everybody loves pasta, especially the spiral kind. But on the nanoscale, they just don't taste the same. Carbon nanotubes and nanofibers that look like nanoscale spiral pasta have completely different electronic properties than their non-spiraling edible cousins.A team of engineers at UC San Diego, and Clemson U... |

A new low-density aerogel has been created by researchers at the University of Pennsylvania. It's made of carbon nanotubes and exhibits extraordinary characteristics, being able to sustain a mass 8,000 times bigger than its own.Aerogels are low-density gel-like solids, where the liquid component of the gel has ... |

For the past decade, nanotubes were considered to be the best candidate for replacing silicon in the competition for miniaturization of the computer industry.Unfortunately, they still had disadvantages, being difficult to arrange precisely, and hard to wire to the outside world without losing much of their vaunted e... |

The fullerenes, discovered in 1985 by researchers at Rice University, are a family of carbon allotropes named after Richard Buckminster Fuller and are sometimes called bucky balls. They are molecules composed entirely of carbon, in the form of a hollow sphere or ellipsoid.A carbon nanotube is a one-atom thick sheet ... |

One of the biggest problems with computers is the residual heat, which requires large, often noisy cooling systems, but can also physically damage internal components, and as portable devices become smaller and slimmer, finding a way to cool them down is an important challenge for manufacturers around the world.As p... |

Nanomaterials are regarded as a great hope for many medical fields, like fighting against tumors. But as in the case of every new technology, the size, type, and dispersion of nanomaterials are not well understood in how they could impact human health and the environment. Two new researchers at Rensselaer Polytechnic... |

The chivalry age is going to be revived, but unlike the medieval knights, the modern ones will wear polymer, not metal, armors. Now, a project conducted by Florida State University researcher Okenwa Okoli, an associate professor of industrial and manufacturing engineering, is going to produce even lighter and effecti... |
