Conventional curved lenses, which direct light by refraction in glass or plastic, are often bulky and heavy, offering only limited control of light waves. Metasurfaces, in contrast, are flat and ...

When materials are created on a nanometer scale—just a handful of atoms thick—even the thermal energy present at room ...

Physicists at SLAC National Accelerator Laboratory in the US have shattered the record for most powerful beam of electrons ... have been a vital tool for physicists for nearly a century, using ...

Key Laboratory of Photochemical Conversion and Optoelectronic Materials, Technical Institute of Physics and Chemistry, University of Chinese Academy of Sciences, Chinese Academy of Sciences, Beijing ...

A laser-shaped electron beam with five times more peak current opens new possibilities in astrophysics, quantum research, and accelerator technology.

This paper utilizes a compound optimization algorithm to design a super high frequency quartz resonator with a center frequency of 4.15GHz and successfully fabricates the device using electron beam ...

The researchers created their experimental nanodots using electron beam lithography—a technique that uses a focused beam of electrons to draw custom shapes on special materials sensitive to electrons.

We present a reconstruction of radiation belt electron fluxes using data assimilation with low-Earth-orbiting Polar Orbiting Environmental Satellites (POES) measurements mapped to near equatorial ...

Players can move their character, the triangle, around using a joystick – what they are actually doing is manipulating the scanning patterns of an electron beam. These beams are used to generate ...

The National Academies of Sciences, Engineering, and Medicine are private, nonprofit institutions that provide expert advice on some of the most pressing challenges facing the nation and world. Our ...
