(Phys.org)—Fujifilm is working on a new recording method for optical discs. It has developed the new method through the use of two-photon absorption in order to generate heat, and the report in TechOn! notes that this two-photon ...
(Phys.org)—An international team of astronomers and astrophysicists has found some unusual spectral activity involving an otherwise "normal" pulsar; it displayed some absorption lines, which generally only occurs with bodies ...
Addressing a half-century-old question, engineers at Stanford have conclusively determined how collective electron oscillations, called plasmons, behave in individual metal particles as small as just a few nanometers in diameter. ...
