Foresight Nanotech Institute Weekly News Digest: March 8, 2006
In this issue:
Foresight has articulated six critical challenges that humanity faces which can be addressed by nanotechnology. In the Weekly News Digest we identify news items, research breakthroughs, and events citing current research and applications providing the stepping stones to solutions to these challenges.
Foresight note: Nanotechnology will enable us to employ new processes to extract energy from raw materials. This article discusses one such process that Chevron is investigating.
Headline: Nanotech of the North: Chevron's use of nanotech could minimize risk in reaping Canada's oil sands
Chevron recently announced a $60 million acquisition of the leases to 75,000 acres in northern Canada in order to develop a giant oil-sands project. The risky venture could ultimately cost tens of billions of dollars and take up to a decade to develop, since the tar in the oil sands isn't easily converted to usable oil. But Chevron may have a very tiny ace up its sleeve, thanks to its involvement with nanotechnology.
Foresight note: We are highlighting a promising company that is working towards a solution to the clean water challenge.
Headline: Nanofiltration – Filtration Overview
Nanofiltration is a low to moderately high pressure (typically 50 - 450 psig) process in which monovalent ions will pass freely through the membrane but highly charged, multivalent salts and low molecular weight organics will be rejected to a much greater degree. Typical NF applications include water softening, desalination of dyestuffs, acid and caustic recovery and color removal.
Foresight note: This research focuses on using nanocages to target melanoma cancer cells.
Headline: Protein Nanocages Target Melanoma Cells
Using a nanoscale protein cage capable of entrapping small molecules, researchers at Montana State University have created a novel nanoparticle that can efficiently target the rapidly growing blood vessels that surround tumors. Engineered protein cages hold promise as nanoscale delivery devices because they are precisely defined structures that are relatively easy to mass-produce. The results of this effort have been published in the journal Chemistry & Biology.
A research team headed by Montana State colleagues Trevor Douglas, Ph.D., and Mark Young, Ph.D., chose to work with a heat shock protein isolated from bacteria that thrives at high temperature. The investigators had previously shown that this protein, which consists of 12 subunits that self- assemble into an empty 12-nanometer diameter cage, could be readily manipulated using both chemical and genetic modifications without affecting its integrity or size.
Foresight note: This conference features several sessions on nanotechnology and food processes.
Headline: Food Colloids – Self Assembly and Material Science Congress and Exhibition
The Food Colloids 2006 conference will be held April 23-26, 2006, and features discussions how the properties of food dispersion, emulsions, foams or gels can be described by concepts used in Material Science or Soft Condensed Matter Physics. A major goal of this science area is to understand the formation processes, structure, and functional properties of supramolecular systems that play an important role in real life. This implies the probing and understanding of structure formation and dynamical properties at the mesoscopic scale of soft materials, such as colloids, polymers or surfactants (e.g., Self-Assembly systems), i.e., materials that are easily deformable by external stresses or even thermal fluctuations.
The practical aim is to be able to control the quality of food products, such as taste, texture, color, shelf life or their nutritional value, and to give guidelines on how to formulate new structures of high quality by using Material Science concepts. Synthetic, biological and food materials ranging from model systems through to specific biological or food problems will be discussed.
Foresight note: This research has developed a single molecule that can function as a diode, the electrical version of a valve.
Headline: USF Researcher Works on Single Molecule Diode
Researchers from the University of South Florida, the University of Chicago and the Russian Academy of Sciences (Moscow) have recently developed the principles of operation and completed an experimental testing of a single molecule for use as a diode. A paper explaining their research has just been accepted for publication in Physical Review Letters by the American Physical Society.
"Single molecule diodes are the fundamental building blocks of an emerging technology called nanoelectronics,' a field that holds promise for application in all kinds of electronic devices, from cell phones to sensors," said Ivan Oleynik, a physics professor at USF and coauthor of the paper. "Molecular diodes could be built a thousand times smaller than diodes in use now."
Computer industry execs might start breathing easier because their biggest fear — that smaller and faster devices will eventually come to an end because silicon microchips will get so small that eventually they will contain too few silicon atoms to work — might be lessened as advancements in molecular electronics come to the rescue.
Foresight note: The National Space Society and The Planetary Society are hosting a conference. One track focuses on nanotechnology. Deadline for talk submission is March 15, 2006.
Headline: International Space Development Conference
ISDC 2006 will feature dozens of presentations, panel discussions, interactive exhibits and activities spanning the entire spectrum of space-related issues: exploration, tourism, science, technology, policy, and commerce.

Dear readers — When reviewing news for this digest, I often read about something that I think is cool, but it doesn't fit within the usual editorial categories of the News Digest. This section highlights a nanotech advance or idea that I think is especially cool.
GE Global Research recently launched a technology blog. Titled "From Edison's Desk," this site features blog entries by scientists at GE's R&D labs posting about their research. I pulled a quote from the following post because it epitomizes the collaborative nature of nanotechnology research. Also, superhydrophobicity, which may enable us to have self-cleaning cars and jars that empty easily, is very cool as well.
Headline: Honey rolls right off!
Once the first discovery was made, we built our model system and were able to figure out many interesting things about water-repellent properties. The team is getting huge. Think about what can happen when you put chemists, materials scientists, physicists, chemical and mechanical engineers in one room; new designs, new processes, new materials are being discovered every week, every day! It's such an exciting time!
