In this paper, we predict an unexpected perfect optical absorption phenomenon of oblique-incident transverse magnetic polarized light in a metallic grating situated in asymmetric surroundings. Two ...

A scanning transmission X-ray microscope illuminated with synchrotron light was used to investigate the speciation and spatial distributions of metals in a microbial biofilm cultivated from river ...

“It has been a ray of light, a ray of hope and that’s both because of the way that Zohran has committed to building a grassroots campaign and it’s also because we know what’s at stake,” said ...

They used polarized light microscopy to observe the transition from disordered states to partially ordered and then fully ordered liquid crystalline phases. Cryogenic electron microscopy provided high ...

In an elegant fusion of art and science, researchers at Rice University have achieved a major milestone in nanomaterials engineering by uncovering how boron nitride nanotubes (BNNTs)—touted for their ...

Welcome to The Lead, a regular podcast from News24 showcasing the best of our in-depth reporting.

Light fields (LFs) have been shown to enable photorealistic visualization of complex scenes. In practice, however, an LF tends to have a relatively small angular range or spatial resolution, which ...

We present a new nonlinear optical technique to probe chirality, i.e., lack of reflection symmetry, of surfaces and thin molecular films. The technique is based on second-harmonic generation and ...
