Seeing light emerge from a nanoscale experiment didn't come as a big surprise to Rice University physicists. But it got their attention when that light was 10,000 times brighter than they expected.
The Micro-nano Optics and Technology Research Group led by Prof. Lu Yonghua and Prof. Wang Pei from University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) realized nanometric displacement ...
Scientists from the Center for Photonics and 2-D Materials of the Moscow Institute of Âé¶¹ÒùÔºics and Technology (MIPT), the University of Oviedo, Donostia International Âé¶¹ÒùÔºics Center, and CIC nanoGUNE have proposed a new way ...
The vortex beam with orbital angular momentum (OAM) is a new and ideal tool to selectively excite dipole forbidden states through linear optical absorption. The emergence of the vortex beam with OAM provides intriguing opportunities ...
Researchers have created a Bose-Einstein condensate with record speed, creating the fascinating phase of matter in about 100 femtoseconds. To get an idea of how quick that is, hundred femtoseconds compared to one second is ...
Life depends on remarkable arrays of biochemical reactions. Understanding the workings of biomolecules involves real-time monitoring of these reactions. Happening in only tiny fractions of a millisecond, this is very difficult ...
Nanolight sources based on resonant excitons of plasmons near a sharp metallic nanostructure have attracted great interest in optical nanoimaging. However, the resonant phenomenon only works for one type of wavelength that ...
A new film made of gold nanoparticles changes color in response to any type of movement. Its unprecedented qualities could allow robots to mimic chameleons and octopi—among other futuristic applications.
Chemists at RIKEN have discovered why shining light on silver nanoparticles causes oxygen molecules attached to their surfaces to break off. This insight will help researchers design new catalysts that harness light energy.
