Chiral sources for metamaterial interface waveguides

Metamaterial interface waveguides can confine and guide electromagnetic (EM) waves, which has attractive potential in integrated photonics physics and wireless devices, from radio frequencies to optical bands. The energy ...

Making it easier to differentiate mirror-image molecules

Using a new method, scientists are better able to distinguish between mirror-image substances. This is important amongst others in drug development, because the two variants can cause completely different effects in the human ...

Tracking chirality in real time

Chiral molecules exist in two forms, called enantiomers, which are mirror images of each other and non-superimposable—much like a pair of hands. While they share most chemical and physical properties, enantiomers can have ...

Controlling chemical mirror images

Chirality, while not a rarity in the world of molecules, is nevertheless a special property. If a molecule is chiral (from the Greek word chiros = hand), it exists in two mirrored versions that are very similar but not identical—like ...
