Ancient and Modern Printing Technologies Combine to Solve a Stubborn Nano-Fabrication Problem.

By Tom Imerito

UCLA-CNSI -K copyIn the half-century since Nobel Laureate, Richard Feynman gave his landmark, 1959 lecture, “There’s Plenty of Room at the Bottom,” the field of nanotechnology has come a long way. As Professor Feynman prophesied, microscopes 100 times more powerful than those available then have become a reality. Today, scientists can pick up individual atoms, put them exactly where they want, and take pictures to prove they did it.

Nevertheless, the grand challenge of scaling bottom-up manufacturing to commercial production levels has remained elusive. [Continue Reading…]

An Excursion to Nano-Land on Penn State's Ultra Stable Scanning Tunneling Microscope

Several years ago, while working on a story about nanotechnology, I had the good fortune to come upon a friendly and generous Penn State professor of physics and chemistry, named Paul Weiss. (Paul now heads UCLA’s California Nanosystems Institute) Little did I know when we first met, that Penn State’s Weiss Group Laboratory was home to the mother of all scanning probe microscopes (SPMs), the renowned ultra-stable, extreme-high-vacuum, low temperature scanning tunneling microscope (STM), of which there are fewer than 10 in the world.
