The nonrepeating Smith hat tile created twisting, pinwheel-like light patterns that ordinary quasicrystals do not produce. Its unusual effect comes from combining long-range order with a lack of ...

Researchers at the George W. Woodruff School of Mechanical Engineering have developed a new approach to nanoscale 3D printing ...

A combined team of engineers from Jiangsu University and Harvard University used a non-destructive, light diffraction fingerprint technique to detect viral infections in cells. Their paper is ...

Researchers at Harvard University and Jiangsu University developed a technique for not only identifying infected cells, but also tracking the infection over time as the cells developed. They published ...

Increasingly complex applications such as artificial intelligence require ever more powerful and power-hungry computers to run. Optical computing is a proposed solution to increase speed and power ...

A U.K.-Portuguese research group is proposing a new solar cell design based on diffraction gratings – optical components that split and diffract light into several beams. They claim this could lead to ...

It therefore seemed impossible to compress light strongly in dielectric materials such as silicon, which are key materials in information technologies and come with the important advantage that they ...

Stars in the new images from the James Webb Space Telescope look sharper than they did before. And I’m not just talking about the image quality, which is astounding. I’m talking about the fact that ...

Did you have the same question as I did when you looked at the spectacular first light images from the $10 billion James Webb Space Telescope (JWST or “Webb” for short)? Yes, they are all incredible, ...

Electron diffraction is a powerful analytical technique used to study the atomic structure of materials. It involves the interaction of a beam of electrons with a crystalline sample, resulting in a ...
