Three-Dimensional Nanofabrication Using Electron Beam Lithography
- The world's smallest globe with a resolution 100 times higher than previously possible -
Nippon Telegraph and Telephone Corporation (NTT; Head Office: Chiyoda-ku, Tokyo; President: Norio Wada) has created an electron beam (EB) lithography (*1) system that enables the fabrication of extremely small three-dimensional (3D) structures with sizes measured in nanometers (A nanometer is a billionth of a meter). NTT demonstrated the 3D nanopatterning and nanofabrication by exposing a small sphere to the EB to form the world's smallest globe. This highly advanced technique promises to become the technological foundation of nanotechnology (*2), which is expected to give rise to many new industries and new markets. ...read the wave www.nano-tsunami.com

RESEARCHERS CREATE DEVICE THAT DETECTS MASS OF A SINGLE VIRUS PARTICLE

PURDUE RESEARCHERS CREATE DEVICE THAT DETECTS MASS OF A SINGLE VIRUS PARTICLE
USA: Researchers at Purdue University have developed a miniature device sensitive enough to detect a single virus particle, an advancement that could have many applications, including environmental-health monitoring and homeland security.

The device is a tiny "cantilever," a diving board-like beam of silicon that naturally vibrates at a specific frequency. When a virus particle weighing about one-trillionth as much as a grain of rice lands on the
cantilever, it vibrates at a different frequency, which was measured by
the Purdue researchers.

"Because this cantilever is very small, it is extremely sensitive to added mass, such as the addition of even a single virus particle," said Rashid Bashir, an associate professor of electrical and computer engineering and biomedical engineering. read the wave at www.nano-tsunami.com

The Nano-Ostrich Approach Doesn't Work
By Glenn Harlan Reynolds

Ostriches don't really bury their heads in the sand when confronted with danger. People, however, sometimes do.

Certainly that seems to be what's happening with the nanotechnology industry. Last week, I wrote about prospects for nanotechnology, and in particular about what I saw as the nanotechnology business community's rather shortsighted efforts to dampen public debate on the subject. I thought it was rather clear that my column, like all my nanotechnology writings, came from a generally pro-nanotechnology standpoint, though I concluded:…read the wave www.nano-tsunami.com

IBM brings closer to reality chips that put themselves together by Gary Stix

Self-assembly has become a critical implement in the toolbox of nanotechnologists. Scientists and engineers who explore the nano realm posit that the same types of forces that construct a snowflake--the natural attractions and repulsions that prompt molecules to form intricate patterns--can build useful structures--say, medical implants or components in electronic chips. So far much of the work related to self-assembling nanostructures has been nothing more than demonstrations in university laboratories. To go beyond being a scientific curiosity, these nanotech materials and techniques will have to get from benchtop to a $2-billion semiconductor fabrication facility.…read the wave www.nano-tsunami.com

CONTROLLING MATERIAL STRUCTURE AT NANOSCALE MAKES BETTER THERMAL INSULATOR Heat may be essential for life, but in some cases - such as protecting the space shuttle or improving the efficiency of a jet engine - materials with low thermal conductivities are needed to prevent passage of too much heat. As reported in the Feb. 13 issue of the journal Science, researchers have created a better thermal insulator by controlling material structure at the nanoscale.

Physicists in Austria have observed decoherence - the transition from quantum to classical behaviour - in carbon-70 molecules. At temperatures below 1000 Kelvin the molecules demonstrate quantum behaviour when they pass through a double slit. However, the molecules gradually become classical at higher temperatures, and the interference pattern - which is the classic sign of quantum behaviour - becomes weaker…read the wave www.nano-tsunami.com

OHSU researchers discover way to grow silicon nanowires
OGI School of Science & Technology Research is one of a kind in Northwest

Oregon Health & Science University researchers have discovered a new way to accurately grow silicon nanowires on an electrode for use in fabricating transistors. A portion of these findings will be published in the Feb. 23 issue of Applied Physics Letter. The discovery has important implications for semiconductor research and may one day help engineers build faster computer chips.

A research group led by Raj Solanki, Ph.D., professor of electrical engineering professor in OHSU's OGI School of Science & Engineering, recently demonstrated it is possible to grow silicon nanowires exactly where you want them on an electrode using electrical fields. Solanki's team also can grow silicon-based nanowires in the exact direction necessary to fabricate electronic devices.

Nano Tsunami:First robot moved by muscle power
« Reply #19 on: February 26, 2004, 10:02:18 AM »
A SILICON microrobot just half the width of a human hair has begun to crawl around in a Los Angeles lab, using legs powered by the pulsing of living heart muscle. It is the first time muscle tissue has been used to propel a micromachine.
This distinctly futuristic development could lead to muscle-based nerve stimulators that would allow paralysed people to breathe without the help of a ventilator. And NASA- which is funding the research- hopes swarms of crawling "musclebots" could one day help maintain spacecraft by plugging holes made by micrometeorites.

Whatever the ultimate applications of the technology, no one was more surprised to see the tiny musclebots finally move than Carlos Montemagno, the microengineer whose team is developing them at the University of California, Los Angeles. He has spent three disappointing years trying, and failing, to harness living muscle tissue to propel a micromachine. But when he and his team looked into their microscopes, they were amazed to see the latest version of their musclebot crawling around ...read the wave www.nano-tsunami.com

Scientists at the MESA+ Institute for Nanotechnology at the University of Twente in the Netherlands have used the self-assembly of hydrogen-bonded rosettes to create nanostructures containing gold. The technique could have applications in the fabrication of nanowires.

“We demonstrated that the incorporation of metal atoms is fully compatible with the bottom-up strategy of building rosette assemblies via multiple hydrogen bonding,” Mercedes Crego-Calama told nanotechweb.org. “Normally this approach is carried out using biomolecules such as DNA that are less stable than the synthetic molecules presented here.” …read the wave www.nano-tsunami.com
