Particles so small that only the newest and most sensitive instruments can see and study them are being used to create new materials and devices that could revolutionize everything from drug delivery to sunscreens. That encouraging revelation comes from Robert W. Hunt, a professor of materials science and engineering at Rensselaer Polytechnic Institute (Troy, NY). Hunt heads a committee for the World Technology Evaluation Center that the National Science Foundation and other federal agencies have contracted to conduct a two-year, $400,000 study of nanotechnology around the world. Nanotechnology, a rapidly expanding scientific field, is in an early stage of development not unlike that of computer and information technology in the 1950s. Siegel, who coined the phrase "nanophase" materials, explains that new tools are letting scientists and engineers characterize and manipulate materials at the nanoscale level. For instance, he works with materials comprised of common atoms arranged in grains less than 100 nm in diameter--10,000 times smaller than grains in conventional materials. Researchers use them as building blocks to create materials with entirely new properties. Recently, members of Siegel's committee spent a week in Japan and in western Europe visiting sites conducting research on such materials. A report on their findings is due out this spring.

If you see a hitchhiker along the road in Canada this summer, it may not be human. That’s because a robot is thumbing its way across our neighbor to the north as part of a collaborative research project by several Canadian universities.
Stanford University researchers have found a way to realize what’s been called the “Holy Grail” of battery-design research -- designing a pure lithium anode for lithium-based batteries. The design has great potential to provide unprecedented efficiency and performance in lithium-based batteries that could substantially drive down the cost of electric vehicles and solve the charging problems associated with smartphones.
Robots in films during the 2000s hit the big time; no longer are they the sidekicks of nerdy character actors. Robots we see on the big screen in recent years include Nicole Kidman, Arnold Schwarzenegger, and Eddie Murphy. Top star of the era, Will Smith, takes a spin as a robot investigator in I, Robot. Robots (or androids or cyborgs) are fully mainstream in the 2000s.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
