Nano Electronic Revolution Begins

June 6th, 2005 | Filed under: Computing, Fabrication Tech, Future, Nanotech, News, Technology | No Comments »

Researchers at the National Institute for Nanotechnology (University of Alberta) have demonstrated for the first time that the charge of a single atom on a silicon surface can switch the conductivity of a nearby molecule. Robert Wolkow and his team’s demonstration bring nano electronics a leap forward into reality, as the technology moves hence forward with proof of a molecular transistor. [press release]

Nanomovies : Rapid Atomic Force Microscope

May 7th, 2005 | Filed under: Mechanical Tech, Nanotech, Photography, Technology, Video | No Comments »

Moshiur Anwar and Itay Rousso have demonstrated an atomic force microscope (AFM) that can take images of periodic processes with a time resolution of microseconds. Instead of sampling a surface by moving the microscopic probe, the probe is kept stationary in “force-sensing” mode as it records changes in up and down movements over time. The technique can only record repetitive nano-scaled movements which allow the microscope to move over and continue sampling the same movement for every pixel of the final constructed movie.

Quantam Wires : Carbon Nanotube Power Cables

April 28th, 2005 | Filed under: Fabrication Tech, Future, Materials, Nanotech | No Comments »

NASA is funding development of carbon nanotube power cables or quantam wires at Rice University which are 10 times more conductive and 1/6th the weight of copper wire. Quantam wires will replace the copper wires in space shuttles with potential applications varying from space elevator tethers to flat panel displays.

Molecular Media Project : Remixing with Fungus

April 27th, 2005 | Filed under: Biology, Biotech, Design, Nanotech, Technology | No Comments »

By manipulating the written bits of digital media, the Molecular Media Project remixes images, music, and video by reorganizing the digital sequence at the nano-scale. Take for example, the remixing of digital music by growing spores of fungus on CDs. The semi-controlled fungus growth refracts the laser as it reads the information, creating different audio effects. From the description you would expect the digital manipulation to sound like a scratched CD, but surprisingly the sounds can overlap and resequence into something bearable.

Motheye and MARAG : Nano-Scaled Anti-Reflective Coating

April 22nd, 2005 | Filed under: Fabrication Tech, Materials, Nanotech, Products | 1 Comment »

The eyes of moths have evolved to collect as much light as possible without reflection, in order to prevent moths being detected by predators. Motheye and MARAGâ„¢ films mimic this property with nano-scaled bumps reducing reflectivity to less than 1%.

Silver Superlens : Nano-Scaled Optical Imaging

April 22nd, 2005 | Filed under: Biology, Future, Nanotech, News, Photography, Technology | 1 Comment »

Optical microscopes today can focus at about 400 nanometers (enough magnification to see the nucleus of a cell). By using a film of silver and UV light, the superlens can focus at about 60 nanometers. Sharper optics produced by enhancing evanescent waves as they pass the silver superlens, will allow nano-scaled visualization of living materials such as the movements of individual proteins in real-time. The technology would also bring imaging in various industries such as data storage and satellite imaging to a new level.

TETwalker : NASA's Tetrahedral Nano Robot Swarm

March 31st, 2005 | Filed under: AI, Future, Mechanical Tech, Nanotech | 3 Comments »

NASA’s new shape-shifting robot, TETwalker, could help the endurance of future spacecrafts. Its structure is a tetrahedron, consisting of telescoping struts and motors which are coordinated to shift the robot’s center of gravity, causing a tumbling motion.

The robot’s inherently rigid geometry coupled with its mode of locomotion make it an ideal candidate for the harsh conditions of space exploration. The current prototype, though not nano-scaled, is going through rigorous test to help optimize its performance. When the nano-scaled robot is realized, it would have the capacity to connect and disconnect from other TETwalkers, allowing an entire swarm of robots to form any shape as “autonomous nanotechnology swarmsâ€?, or ANTS.

Nanosolar : Printing Photovoltaic Sheets

March 7th, 2005 | Filed under: Fabrication Tech, Nanotech, Products, Sustainability | 7 Comments »


Nanosolar Inc. claims to have broken several barriers to ubiquitous solar energy.  Their manufacturing process consists of printing nano-scaled solar-cell layers, bypassing the traditionally expensive vacuum methods yet meeting and in some cases, exceeding industry standards.  Major claims include a 3 week payback time and lightweight flexible panels.
