Researchers are developing a real-life tractor beam, with the goal of pulling defunct satellites out of geostationary orbit to alleviate the space junk problem. When you purchase through links on our ...

Spreading the laser beam's intensity out reduces the temperature difference between sections of the part being printed. Laser powder bed fusion (LBPF), a 3D printing technique commonly used to make ...

Light propagates in a three-dimensional photonic circuit to solve the subset sum problem. The image of the reconfigurable photonic processor is based on the research presented. As technology advances, ...
