'Diamane': Diamond film possible without the pressure
(Phys.org) —Perfect sheets of diamond a few atoms thick appear to be possible even without the big squeeze that makes natural gems.
Scientists scale terahertz peaks in nanotubes
(Phys.org) —Carbon nanotubes carry plasmonic signals in the terahertz range of the electromagnetic spectrum, but only if they're metallic by nature or doped.
When aluminum outshines gold: Research details aluminum's valuable plasmonic properties
(Phys.org) —Humble aluminum's plasmonic properties may make it far more valuable than gold and silver for certain applications, according to new research by Rice University scientists.
Polymer gel, heal thyself: Team proposes new composites that can regenerate when damaged
(Phys.org) —When a chair leg breaks or a cell phone shatters, either must be repaired or replaced. But what if these materials could be programmed to regenerate-themselves, replenishing the damaged or missing ...
