Spintronics has emerged as a promising frontier in information technology, offering non-volatility, ultrafast switching, and energy-efficient operation surpassing traditional electronic memory devices ...

Chirality is a fundamental property of matter that determines many biological, chemical and physical phenomena. Chiral solids, for example, offer exciting opportunities for catalysis, sensing and ...

Schematic illustration of MEMS-integrated twisted bilayer photonic crystals illuminated by right-handed circularly polarized and left-handed circularly polarized beams. Harvard engineers have built a ...

Chirality refers to the property of an object that cannot be superimposed on its mirror image. Chiral molecules and their mirror images are called enantiomers, which are denoted as “D” (dextrorotatory ...

A terahertz platform built on an achiral gradient metasurface resolves the components, handedness, and mixing ratios of chiral biomolecule mixtures in a single broadband measurement. (Nanowerk ...

Engineers created a MEMS-tunable twisted bilayer photonic crystal chip that dynamically adjusts twist angle and spacing to control light chirality and distinguish circular polarization. (Nanowerk News ...
