Perfection does indeed come from flaws, as a new discovery in the fields of nanotechnology and energy conductivity indicates. Namely, a team of US experts managed to alter the internal structure of carbon nanotubes that typically behaved as insulators so that now it performs better than the traditionally-used silicon... |

Materials built from double-walled carbon nanotubes (DWNTs) have unique properties derived from the combination of features from single-walled nanotubes (SWNTs) and multi-walled nanotubes (MWNTs). Transparent conductors, for instance, are best fit for solar energy cells or flat displays, and as the need for these inc... |

Nanomaterials are that kind of material made of parts less than one tenth of a micrometer (less than a thousandth of a human hair) in at least one dimension, sporting particular features and characteristics. In the related section of this article, you can check out some of the latest uses of such materials. To put it... |

The newest wonder coming from the small world of nanotubes is the buckypaper, which resembles carbon paper in appearance and manipulation but is, in fact, 10 times lighter and 500 times tougher than steel. In the future, when the technology is up and running and the buckypaper is made on a commercial scale, it could... |

Geckos have an odd ability that seems to allow them to defy gravity; it has been puzzling scientists (and superhero comics authors) for decades, as they hang upside-down on vertical surfaces with the least of efforts. By analyzing the Gecko feet, researchers were able to come up with a material that surpasses the res... |

The car batteries that we rely on today may be soon "driven" to extinction by recent discoveries. Engineers' old engine power-delivery problem has now been solved by means of the new supercapacitor. Post-doctoral researcher Jiyoung Oh together with research scientist Mikhail Kozlov from the NanoTech Instit... |

Typical computers today have two main components interacting with each other dynamically in order to process data: the central processing unit and the memory core. The memory core of the computer relies mostly on magnetic components, while the central processing unit uses electrical signals to operate. Nonetheless, U... |

Rensselaer Polytechnic Institute researchers have released a report claiming that carbon nanotubes are better than copper interconnects when performing at the 45-nm process node. The scientists used for the first time a supercomputer simulation with detailed quantum mechanical effects, which shown that copper cannot... |

Robocop is coming. What you've seen in SF movies featuring invincible heroes can now turn into reality. A Cambridge team has employed nanotechnology to achieve a super-strong body armor for the military and law enforcement. The new material is 5-10 times stronger, tougher and stiffer than what current technology... |

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. Polymers are repeating structural units, or monomers, connected by covalent chemical bonds, present in many natural and artificial materials, from ... |

Few people know that not all materials normally stick together, but many of you have had troubles sticking two surfaces together that no superglue seemed to be able to hold in place. Scientists encounter problems in their endeavor, and they usually turn to Mother Nature to solve their problems.The Gecko is a small l... |
