Scientists from the Center for Photonics and 2-D Materials of the Moscow Institute of Â鶹ÒùÔºics and Technology (MIPT), the University of Oviedo, Donostia International Â鶹ÒùÔºics 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.
Miniaturization has enabled technology like smartphones, health watches, medical probes and nano-satellites, all unthinkable a couple decades ago. Just imagine that in the course of 60 years, the transistor has shrunk from ...
Terahertz lasers could soon have their moment. Emitting radiation that sits somewhere between microwaves and infrared light along the electromagnetic spectrum, terahertz lasers have been the focus of intense study due to ...
Researchers of Tomsk Polytechnic University with Russian and Danish teams have been able to experimentally confirm a plasmonic nanojet effect previously forecast in practice. Using a simple method, they focused surface plasmon ...
