Spontaneous demixing of chiral active mixtures in motility-induced phase separation

New Journal of Physics, 2023
The demixing and sorting strategies for chiral active mixtures are crucial to the biochemical and pharmaceutical industries. However, it remains uncertain whether chiral mixed particles can spontaneously demix without the aid of specific strategies.

All-optical separation of chiral nanoparticles on silicon-based microfluidic chips with vector exceptional points

APL Photonics, 2023
Surface-enhanced all-optical separation of chiral molecules plays an important role in the field of chiral recognition. However, the originally designed photonic micro/nano-structures are always suffering from a lot of limitations, such as low strengths ...

Anomalous Maxwell equations for inhomogeneous chiral plasma [PDF]

, 2016
Using the chiral kinetic theory we derive the electric and chiral current densities in inhomogeneous relativistic plasma. We also derive equations for the electric and chiral charge chemical potentials that close the Maxwell equations in such a plasma ...

Visualization of enantioselective recognition and separation of chiral acids by aggregation‐induced emission chiral diamine

Aggregate, 2023
Enantioselective recognition and separation are the most important issues in the fields of chemistry, pharmacy, agrochemical, and food science. Here, we developed two optically active diamines showing aggregation‐induced emission (AIE) that can ...
