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.

"We were initially puzzled by the unexpectedly strong X-ray diffraction signals during our experiments at the Linac Coherent Light Source (LCLS)," says Tais Gorkhover, one of the study's lead ...

Innovative research by Antonio Ambrosio presents a new material and technique for temporal light control, driving progress in nanophotonics and optoelectronics.

Ultrawide-bandgap semiconductors—such as diamond—are promising for next-generation electronics due to a larger energy gap between the valence and conduction bands, allowing them to handle higher ...

Researchers have built a deep-ultraviolet microscope to study hard-to-analyze materials like diamond, offering a new way to probe their electronic and thermal properties at the nanoscale. This ...

Researchers introduce a cost-effective method for producing optical Fresnel zone plate lenses, using colored photoresists for enhanced light manipulation.

Study reveals how immune cells in the gut distinguish between food and harmful pathogens, shedding light on the origins of both food allergies and intestinal diseases.

The accurate modelling of the point spread function (PSF) is of paramount importance in astronomical observations, as it allows for the correction of distortions and blurring caused by the telescope ...
