In contrast to conventional mirrors, light can be reflected on surfaces known as metasurfaces without changing its polarization. This phenomenon has now been proven by physicists at ...

Meta-atoms at varying orientations on a chiral metasurface. 2025 EPFL Bionanophotonic Systems Lab CC BY SA 4.0 Imagine trying to wear a left-handed glove on your right hand: it doesn’t fit because ...

Chemists have synthesized the first stable molecule whose chirality is solely attributed to a stereogenic oxygen, according to a new study (Nature 2023, DOI: 10.1038/s41586-023-05719-z). Though carbon ...

Chiral phonons excited by the circularly polarized terahertz light pulses generate ultrafast magnetization in cerium fluoride. Fluorine ions (red, fuchsia) are set into motion by circularly polarized ...

Chiral metasurfaces provide invaluable tools for controlling structured light required for biosensing, photochemistry, holography, and quantum photonics. Here we suggest and realize a universal ...

Chiral metal surfaces play a pivotal role in enantioselective catalysis, sensing, and spintronics, yet their scalable fabrication remains challenging due to a reliance on chiral templates or molecular ...

In a surprising twist, researchers have identified crystals that are symmetrical but nevertheless absorb light as if they were chiral (Science 2025, DOI: 10.1126/science.adr5478). The discovery ...

Chirality is a fundamental property of asymmetry in nature, where an object or molecule cannot be superimposed onto its mirror image. In the context of nanotechnology, chirality refers to the ...

C-H activation-based method should speed drug molecule design and diversification. Scripps Research chemists have accomplished a long elusive feat in synthetic chemistry: the invention of a broadly ...

New findings settle the dispute: phonons can be chiral. This fundamental concept, discovered using circular X-ray light, sees phonons twisting like a corkscrew through quartz. Findings published in ...

The center of each image (a) and (b) shows a substitutional silicon defect. The pronounced dark spot at the center of panels (a) and (c), indicated by blue arrows, is a key signature of a chiral ...
