First, the payload requirements and problems faced by traditional multi-beam antenna are described. The user beam of the VHTS payload system mainly uses Ka-band multi-beam antenna for a large range of ...
A new method in electron microscopy enables sub-20-picometer targeting of individual atoms without prior exposure, opening the door to atom-specific analysis and control. (Nanowerk Spotlight) ...
WASHINGTON — Researchers have developed a new method for flexibly creating various needle-shaped laser beams. These long, narrow beams can be used to improve optical coherence tomography (OCT), a ...
A research team led by Associate Prof. Wang Anting from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) proposed a method for multidimensional ...
Electron beam method enables high-yield graphdiyne synthesis in seconds under ambient conditions, offering a fast route to carbon-based catalytic materials. But it differs in a key way: its structure ...
