Inspired by a Cotton Candy Machine, Engineers Put a New Spin on Creating Tiny Nanofibers
Wed, 02 Jun 2010 09:41:00 -0500
Hailed as a "cross
between a high-speed centrifuge and a cotton candy machine," bioengineers at Harvard have developed a new, practical technology for fabricating tiny nanofibers. The reference by lead author Mohammad Reza Badrossamay to the fairground treat of spun sugar is deliberate, as the device literally--and just as easily--spins, stretches and pushes out 100 nanometer-diameter polymer-based threads using a rotating drum and nozzle.

Shape Matters: The Corkscrew Twist of H. Pylori Enables It to 'Set Up Shop' In the Stomach

The bacterium Helicobacter
pylori, which lives in the human stomach and is associated with ulcers and gastric cancer, is shaped like a corkscrew, or helix. For years researchers have hypothesized that the bacterium's twisty shape is what enables it to survive--and thrive--within the stomach's acid-drenched environment, but until now they have had no proof.

Applied Physicists Create Building Blocks For a New Class of Optical Circuits

Imagine creating novel devices with amazing and exotic optical properties not found in nature--by simply evaporating a droplet of particles on a surface. By chemically building clusters of nanospheres from a liquid, a team of Harvard researchers, in collaboration with scientists at Rice University, the University of Texas at Austin, and the University of Houston has developed just that.
