NanoDays Open House

The NanoStar Institute is holding its second NanoDays Open House this Sunday, March 28 at Wilsdorf Hall.  Free, and open to the public, NanoDays’ goal is to introduce our local community to concepts and research associated with nanotechnology.  The Open House runs from 2:00 – 5:00 pm, featuring many interactive demonstrations, games, films, posters and multimedia, and construction of the 30 foot nanotube balloon sculpture.  From 5:00 – 6:15, SEAS professors John Bean and Eric Loth will be presenting lay-level talks on “The Incredible Shrinking Transistor” and “The Ultimate Water Slide”, in ChemE 005.

See http://www.virginia.edu/nanostar/nanodays_2010.html for more information.  I hope you can come, and bring your family.

Best regards,

Paper Batteries

New Batteries Made From Paper, Nanotube Ink.

In a story on the New York Times (12/9, Mandel) website Greenwire reports, “Ordinary office paper coated with an inky layer of carbon nanotubes or nanowires can make a lightweight, flexible and highly conductive battery or superconductor, according to Stanford University researchers.” The researchers “had previously experimented with making batteries using a similar process of painting nanomaterial ink onto a thin layer of plastic,” but discovered “that pores in paper fibers make it hold the ink better than plastic, for a more durable battery.” According to the scientists, “the conductive paper could be used in lithium-ion batteries in place of metallic components, where its light weight and scalability would provide an advantage over technologies now in use.”

        BBC News (12/9) reports, “A team of researchers at Stanford University started with off-the-shelf copier paper” that is painted “with an ‘ink’ made of carbon nanotubes,” and “is then dipped in lithium-containing solutions and an electrolyte to provide the chemical reaction that generates a battery’s electric current.” This method “could reduce the weight of batteries… by 20%,” according to the researchers. In addition to being “capable of releasing their stored energy quickly,” a Stanford researcher “said the most important aspect of the demonstration was that paper is an inexpensive and well-understood material – making wider usage of the technology more likely.”

        Clay Dillow writes in Popular Science (12/8) that the technology “could bring paper right back around to its former place of prominence, using it to power the very digital devices — smartphones, Kindles, laptops, etc. — that are increasingly replacing print.” Dillow adds that “the paper battery technology is basically market-ready. That’s not to say that researchers won’t need some time to iron out the kinks, but power sources based on this technology could be commercialized very soon compared to a lot of the nano-noise circulating in scientific circles.” The article also includes a video clip of Stanford’s Yi Cui explaining the device. Technology Review (12/9, Bourzac) also reports the story.

In the Eye of the Beholder

Researcher Babak A. Parviz of the University of Washington, Seattle, writes in IEEE Spectrum about how nanotechnology will soon be able to create contact lenses capable of superimposing data and information over a wearer’s vision and be able noninvasively to monitor and report on the wearer’s biological or medical state.  Read the full article at

DNA for Microchips

Excerpt from ASEE First Bell, August 18, 2009:

 CNET (8/18, Crothers) reports, “On Monday, IBM researchers and collaborator Paul W.K. Rothemund, of the California Institute of Technology (CalTech), announced an advancement of a method to arrange DNA origami structures on surfaces compatible with today’s semiconductor manufacturing equipment.” Spike Narayan, a manager in the Science & Technology division of IBM Research, stated that “the cost involved in shrinking (chip) features to improve performance is a limiting factor in keeping pace with Moore’s Law and a concern across the semiconductor industry.”      NewsFactor Business Report (8/18, LeClaire) reports that the “scientific advancement…could make way for the semiconductor industry to build more powerful, faster, tinier, more energy-efficient computer chips.” Rothemund and the IBM researchers “reported an advancement in combining lithographic patterning with self-assembly. This method of arranging DNA origami structures on surfaces compatible with today’s semiconductor manufacturing equipment could reduce production costs.”    PC Advisor (8/17, Shah) reported, “Big Blue is researching ways in which DNA can arrange itself into patterns on the surface of a chip, and then act as a kind of scaffolding on to which millions of tiny carbon nanotubes and nanoparticles are deposited.” That network, said IBM scientists, “could act as the wires and transistors on future computer chips.”   ITnews (8/18, Williams), and Silicon Republic (8/17, Kennedy) also reported the story.
