Non-linear optics meets X-rays
The recent advent of femtosecond X-ray sources offers unprecedented opportunities for structural and dynamical studies. It requires, however, manipulating spectral properties, as commonly done by non-linear optics at visible/infrared wavelengths. Her.....»»
A golden layer unlocks sharper imaging and faster scanning with X-rays
Scientists have made a breakthrough in significantly improving the sharpness of X-ray imaging and potentially boosting the speeds at which X-ray scans can be processed. This lays the groundwork for both better medical imaging and faster security clea.....»»
From roots to resilience: Investigating the vital role of microbes in coastal plant health
Georgia's saltwater marshes—living where the land meets the ocean—stretch along the state's entire 100-mile coastline. These rich ecosystems are largely dominated by just one plant: grass......»»
A thousand times smaller than a grain of sand—glass sensors 3D-printed on optical fiber
In a first for communications, researchers in Sweden 3D printed silica glass micro-optics on the tips of optic fibers—surfaces as small as the cross section of a human hair. The advance could enable faster internet and improved connectivity, as wel.....»»
