Creating complex structures at the tiniest scales has long been a challenge for engineers. But new research from Georgia Tech shows how electron beams, already widely used in imaging and fabrication, ...

A novel planar distributed three-beam electron gun with narrow beam separations is designed based on grids loaded sheet beam method. The dimensions of the three-beam gun in the y–O-z plane are ...

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 ...

Acoustic beam shaping with high degrees of freedom is critical for ultrasound imaging, acoustic regulation, and stimulation. The ability to fully regulate the acoustic pressure profile relative to its ...

Over the last four decades significant achievements have been made towards developing scanning helium microscopes (SHeM) 1, which use a neutral beam of very low energy (sub-eV) helium atoms to image ...
