CSIRO scientist discovers natural 'invisible' gold Nanotechnology / Materials June 23, 2008 \| User rating: 3.9 / 5 after 27 vote(s) \| No comments yet The search for these natural but 'invisible' nanoparticles is important. If they can be proved to exist, the knowledge will help give us a deeper understanding of how gold can be transported and deposited by geological processes, ...

New method of growing carbon nanotubes to revolutionise electronics Nanotechnology / Materials August 09, 2006 \| User rating: 4.4 / 5 after 92 vote(s) \| No comments yet A new method of growing carbon nanotubes is predicted to revolutionise the implementation of nanotechnology and the future of electronics. Researchers at the University of Cambridge have successfully grown nanotubes at a ...

University of Pennsylvania engineers reveal what makes diamonds slippery at the nanoscale Nanotechnology / Materials June 23, 2008 \| User rating: 4.1 / 5 after 16 vote(s) \| No comments yet They call diamonds "ice," and not just because they sparkle. Engineers and physicists have long studied diamond because even though the material is as hard as an ice ball to the head, diamond slips and slides with remarkably ...

Nanoscale 'Coaxial Cables' for Solar Energy Harvesting Nanotechnology / Materials April 23, 2007 \| User rating: 4.6 / 5 after 118 vote(s) \| No comments yet Scientists have designed a new type of nanowire – a tiny coaxial cable – that could vastly improve a few key renewable energy technologies, particularly solar cells, and could even impact other cutting-edge, ...

Quantum Dots May Lead to Rainbow Solar Cell Nanotechnology / Materials March 07, 2008 \| User rating: 4.6 / 5 after 112 vote(s) \| User comments: 3 For the first time, researchers have created solar cells made of different-sized quantum dots, each tuned to a specific wavelength of light. By arranging these quantum dots in an ordered pattern, the scientists ...

Stretchable Silicon May Inspire a New Wave of Electronics Nanotechnology / Materials June 13, 2007 \| User rating: 4.4 / 5 after 67 vote(s) \| No comments yet Scientists have created a form of nanoscale silicon that is stretchable. The new material may help pave the way for a class of stretchable electronic devices, such as “smart” surgical gloves and personal health ...

Scientists Create First Non-Carbon Material with Near-Diamond Hardness Nanotechnology / Materials March 28, 2007 \| User rating: 4.5 / 5 after 76 vote(s) \| No comments yet Research scientists have created the first non-carbon-based material with a hardness approaching that of diamond. Their work could have a significant impact on technologies and industries that rely on diamond as a cutting ...

Controlled growth of truly nanoscale single crystal fullerites for device applications Nanotechnology / Materials July 14, 2008 \| User rating: 4.8 / 5 after 10 vote(s) \| No comments yet (PhysOrg.com) -- University of Surrey researchers have found a way to make ultra-small pure carbon crystals entirely formed from the spherical carbon ‘buckyball’ molecule known as C60. The method used involves mixing two ...

New graphene transistor promises life after death of silicon chip (Update) Nanotechnology / Materials February 28, 2007 \| User rating: 4.5 / 5 after 113 vote(s) \| No comments yet Researchers have used the world's thinnest material to create the world's smallest transistor – a breakthrough that could spark the development of a new type of super-fast computer chip.

For Better Nanowires, Just Add Diamond Nanotechnology / Materials November 15, 2006 \| User rating: 4.2 / 5 after 432 vote(s) \| No comments yet Among the positive characteristics of diamond, such as its beauty and unsurpassed hardness, are less well known properties that make it a valuable material in the electronics industry. Now, according to two scientists at ...

Nature’s frugal glues provide insight for optimized adhesives Nanotechnology / Materials January 11, 2007 \| User rating: 4.2 / 5 after 41 vote(s) \| No comments yet In trying to create a “glue” that would hold right up to the breaking point of the material being glued, scientists have found that such an ideal adhesive already exists—in bone, abalone shells, and spider ...

New Nanomaterial, 'NanoBuds,' Combines Fullerenes and Nanotubes Nanotechnology / Materials March 30, 2007 \| User rating: 4.4 / 5 after 64 vote(s) \| No comments yet Researchers have created a hybrid carbon nanomaterial that merges single-walled carbon nanotubes and spherical carbon-atom cages called fullerenes. The new structures, dubbed NanoBuds because they resemble ...

Nanoscience May Produce 'Perfect' Materials Nanotechnology / Materials August 25, 2006 \| User rating: 4.4 / 5 after 55 vote(s) \| No comments yet Nanoscience may provide a way to engineer materials that are virtually defect-free – perfect, that is.

In new hybrid chip, molecules are memories Nanotechnology / Materials August 08, 2006 \| User rating: 4.1 / 5 after 46 vote(s) \| No comments yet As scientists strive to satisfy the growing demand of the digital era for faster, smaller, and cheaper electronics, one of the most promising technologies is hybrids. Hybrid ICs (integrated circuits) consist ...

Ancient Hair-Dyeing – A Nanoscience? Nanotechnology / Materials October 30, 2006 \| User rating: 3.6 / 5 after 31 vote(s) \| No comments yet Scientists have discovered that an ancient method used to darken hair, dating back more than 4,000 years, is based on a chemical process that takes place at the nanoscale. This may be one of the earliest examples ...
