Lanthanide-doped upconversion nanoparticles (UCNPs) demonstrate many superior properties of broadly-tunable multicolor emission and long emission lifetimes. This makes them well-suited for many light-emission applications. ...
Vanderbilt researchers have developed a way to more quickly and precisely trap nanoscale objects such as potentially cancerous extracellular vesicles using cutting-edge plasmonic nanotweezers.
The demand for fast data sharing and processing has sparked a race for greater bandwidth in wireless communication systems. This is described by Edholm's Law, which states that bandwidth and data rates roughly double every ...
Electro-optic modulators (EOMs) are cardinal elements in the optical communication networks that control the amplitude, phase and polarization of a light via external electric signals. Aiming to realize ultracompact and high-performance ...
A research team led by Prof. Liu Xianwei from the Department of Environmental Science and Engineering of University of Science and Technology of China (USTC) of the Chinese Academy of Science (CAS) has made progress in the ...
In 1956, theoretical physicist David Pines predicted that electrons in a solid can do something strange. While they normally have a mass and an electric charge, Pines asserted that they can combine to form a composite particle ...
Squeezing light beyond the diffraction limit and controlling the optical processes caused by nano-confined light are central issues of nanophotonics. In particular, localized and enhanced light at the plasmonic nanogaps in ...
Polarization, as a primary physical quantity of light, is of great interest to almost all optical sciences and technologies. Along with linear polarization detection, circular polarization (or light ellipticity) detection ...
Researchers at the McKelvey School of Engineering at Washington University in St. Louis have pioneered a new technique that will enable higher-resolution imaging of very small objects like neurons. The technique, which improves ...
NH3 is not only the key chemical raw material for the industry but also a carbon-free fuel and mobile carrier of renewable energy in the future. So far, industrial NH3 synthesis is still dominated by the traditional Haber-Bosch ...
