les nanotechnologies : nouveau moteur de la révolution technologique
|
News Item | 2007-06-22 22:32:03 | Une étude de la Commission européenne consacrée à l’essor économique des nanotechnologies, révèle que celles-ci pourraient bien supplanter les biotechnologies et être aussi génératrices de profits que les technologies de l’information et de la communication (TIC). Les auteurs du document recoupent les études menées sur l’essor économique des nanotechnologies, en évaluent les conclusions et cherchent à localiser les secteurs présentant le plus fort potentiel économique. Ils dressent également une comparaison entre l’Europe et ses concurrents dans le secteur des nanotechnologies. |

Nanotechnologies : il faut rétablir la vérité
|
News Item | 2006-06-09 18:15:56 | Avec l’inauguration du « Minatec », à Grenoble, le 2 juin dernier, la France vient enfin de se doter d’un outil exceptionnel, unique en Europe, d’étude et de recherche dans le domaine stratégique des nanotechnologies.qui sont en train de révolutionner, de manière transversale, l’ensemble des disciplines scientifiques et des secteurs industriels. En médecine par exemple, on prévoit que la moitié des médicaments produits dans les dix prochaines années relèveront des nanotechnologies. |

Prospective, perspectives et éthique des nanotechnologies
|
News Item | 2006-09-21 21:59:28 | “Les nanotechnologies : éthique et prospective industrielle” : c’est le titre du remarquable rapport de Jean-Pierre Dupuy et Françoise Roure, que viennent de mettre en ligne - en toute discretion ! - le Conseil Général des Mines et le Conseil Général des Technologies de l’Information. Une lecture courte (60 pages) et aisée, vivement recommandée à ceux qu’intéresse le cycle d’innovation dans lequel nous sommes désormais entrés. |

Quand les nanos préviennent, et réparent, les dommages corporels
|
News Item | 2007-05-14 00:05:44 | Christophe Jacquemin, dans Automates Intelligents, évoque ainsi un gilet pare-balle enrichi de nanoparticules liquides qui se durcissent au moindre choc. Au-delà de la technologie, c’est par la mise en perspective qu’il en fait que son billet vaut le détour. |

Nanocosmetics are used since the Pharaohs
|
News Item | 2006-09-13 20:52:02 | French researchers have found that Egyptians, Greek and Romans were using nanotechnology to dye their hair several thousands years ago. In "Nanotechnology in Cosmetics - 2000 Years Ago...," Nanowerk Spotlight reports they were using lead compounds which generated lead sulfide (PbS) nanocrystals with a diameter of only 5 nanometers. At a moment where many people wonder if the use of nanoparticles is safe, it's good to know that nanotechnology has been widely used for a very long time. |

Nanotech Vs The Green Gang
|
News Item | 2005-04-07 19:44:39 | There could be trouble brewing on the horizon for nanotech. The trouble I am talking about has nothing to do with nanotech's great scientific or commercial promise. It has to do with politics and the media. The "Green Gang" is starting to focus on nanotech research, and governments around the world are listening. There are rumblings that regulations are needed. They say they want to guarantee the safety of the technology and instill confidence in the general public. |

Russia Pours Billions in Oil Profits Into Nanotech Race
|
News Item | 2007-11-01 11:43:04 | Back in the mid-1980s, a joke made the rounds that the Kremlin was preparing a major announcement: After a decade-long top-secret crash program, socialist science had succeeded in building the world's largest microprocessor. That was then. After sleeping through the high tech revolutions of the late 20th century, the Russian government is dumping billions into the burgeoning science of nanotechnology. The Kremlin last June announced the creation of Rosnanotekh, a state nanotechnology corporation slated for $5 billion in initial funding -- an outlay that propels Russia past China in nanotech spending, and puts the country on a par with the United States in government-funded nano research. |

Nanotechnology and Jewelry
|
News Item | 2005-03-05 09:51:59 | Today, we'll look at nanotechnology under an unusual angle: the impact on the jewelry industry. In this long article, "The Weird World of Precious Metal Nanotechnology," published by AJM Magazine (The Authority on Jewelry Manufacturing), Michael Cortie, professor at the University of Sydney, Australia, explains why gold is often used by nanotechnologists. Not only gold exhibits very interesting properties at the nanoscale level, but it's also a bargain when compared to current prices of carbon nanotubes. And gold -- and silver -- nanoparticles can offer a range of unusual colors, suitable for fine jewelry or luxurious coatings. Finally, Cortie envisions smart jewelry made possible through the use of nanotechnology, such as a pendant that could include cell phone capabilities. |

Nanobot naysayers argue that molecular manufacturing is impossible, but the evidence goes against them
|
News Item | 2005-01-28 19:32:31 | Behind the public face of nanotechnology—the press releases, science fiction novels and environmental doomsday reports—a debate has been evolving and swirling for the past decade around a fundamental question: Can tiny machines build things useful to humans by moving molecules or even individual atoms? |

Galénique et squalénisation : deux concepts novateurs au coeur de la nanomédecine
|
News Item | 2007-04-15 09:47:26 | Patrick Couvreur est un chercheur atypique au parcours exemplaire. Belge d’origine, il opte pour la France et le CNRS en 1984, grâce à l’accueil enthousiaste que reçut son concept - alors très original - de vectorisation des médicaments sous forme de nanoparticules. Aujourd’hui, il dirige, à l’Université Paris-Sud, une vaste unité spécialisée, unique au monde par son interdisciplinarité (l’UMR CNRS 8612). |

Nanotechnology's Radical Future
|
News Item | 2006-10-11 09:04:56 | Disruptive change triggered by nanotechnology was on the agenda for a recent three-week speaking tour of Australia and New Zealand conducted by Mike Treder, executive director of the Center for Responsible Nanotechnology (CRN). Between September 2 and September 21, he gave public lectures and held small group discussions on the subject of ‘Disruptive Abundance: Nanotechnology and Human Life’ in twelve cities. “We had big audiences everywhere I went -- overflow in some places,” said Treder. “People were very interested to hear about the profound impacts that advanced nanotechnology will bring to society.” |
