Crystals are supposed to be hard and brittle. But when we make them bendy, they help reveal the secrets of how elastic ...

Researchers in Germany have found a way to accurately study atomic reflections in quantum sensors by deploying special light ...

Laser diodes are semiconductors that generate light and amplify it using repeated reflection or "optical feedback." Once the ...

Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays—without the ...

Scientists have found a way to achieve negative refraction—where light bends the "wrong" way—using carefully arranged atomic ...

In 1873, the German physicist Ernst Abbe realized that the resolution of optical imaging instruments, including telescopes and microscopes, is fundamentally limited by the diffraction of light.

Depending on how an object interacts with light, it could appear vividly colored ... of a meter thick—without relying on traditional diffraction methods to retain the light within the material.

In 1920, astronomers Harlow Shapley and Heber Curtis held a Great Debate. Shapley argued that the spiral nebulae were small ...

This study examines silica-based nanocomposites' dual role in antimicrobial and photocatalytic applications, addressing microbial resistance and pollution.
