- A whole new light on graphene metamaterials: Tunable graphene device is first tool in a kit for putting terahertz light to work
- World's smallest electric motor made from a single molecule
- Fast, cheap, and accurate: Detecting CO2 with a fluorescent twist
| Posted: 04 Sep 2011 11:04 AM PDT Invisible terahertz light can detect explosives, image drug structures, and pinpoint skin cancer, but practical tools for using it are scarce. Scientists have now made a graphene microribbon array that strongly responds to terahertz light by exciting the collective electron oscillations known as plasmons. The device can be tuned with exquisite precision by varying the width of the graphene ribbons and controlling electron density.  |
| World's smallest electric motor made from a single molecule Posted: 04 Sep 2011 11:03 AM PDT Chemists have developed the world's first single molecule electric motor, a development that may potentially create a new class of devices that could be used in applications ranging from medicine to engineering.  |
| Fast, cheap, and accurate: Detecting CO2 with a fluorescent twist Posted: 04 Sep 2011 11:03 AM PDT Detecting specific gases in the air is possible using a number of different existing technologies, but typically all of these suffer from one or more drawbacks including high energy cost, large size, slow detection speed, and sensitivity to humidity. Overcoming these deficiencies with a unique approach, scientists have designed an inexpensive new material capable of quick and accurate detection of a specific gas under a wide variety of circumstances.  |
