Chiral Phonon Diode Effect in Chiral Crystals

Nano Letters, 2022
The diode effect means that carriers can only flow in one direction but not the other. While diode effects for electron charge, spin, or photon have been widely discussed, it remains a question whether a chiral phonon diode can be realized, which utilizes the chiral degree of freedom of lattice vibrations.

Chiral Plasmonic Metamaterials with Tunable Chirality

ACS Applied Materials & Interfaces, 2020
Chiral hollow nanovolcano array (HNVA) film and chiral hollow nanoshells (HNSs) are simultaneously fabricated via a new strategy of colloidal lithography technique. The chirality of both chiral plasmonic nanostructures, which arises from the asymmetric charge oscillation and electric field distributions, can be well controlled by regulating the opening-

Cellular response to chirality and amplified chirality

Journal of Materials Chemistry B, 2013
In this paper we have explored how cancer cell line U87MG responds to drug penicillamine (PA) with reciprocal enantiomeric identities (i.e.l, d-forms). As nano-conjugation leads to amplification of chirality, cellular response to respective chiral forms is studied in the presence and absence of nano-conjugation.

Chirality and Chiral Recognition

2009
This review summarizes the literature survey on chiral recognition from a theoretical view point. Nevertheless, experimental results in the gas phase are reported when they are relevant for the theoretical calculations. The review is divided into the following sections: general considerations; experiment vs.

Chiral measure of chiral polyhedrons

Chirality
AbstractTo quantify chiral shape, a tensor describing the particle shape has been proposed. This tensor, named the shape tensor (S‐tensor), is an analog of the hydrodynamic tensor that relates the rotational and translational motions of particles in a liquid.

Chiral Magnetic Soliton Lattice on a Chiral Helimagnet

Physical Review Letters, 2012
Using Lorenz microscopy and small-angle electron diffraction, we directly present that the chiral magnetic soliton lattice (CSL) continuously evolves from a chiral helimagnetic structure in small magnetic fields in Cr(1/3)NbS2. An incommensurate CSL undergoes a phase transition to a commensurate ferromagnetic state at the critical field strength.

Chiral cyclotrisiloxanes

Dalton Transactions, 2010
We have synthesized and separated the enantiomer pair of chiral cyclotrisiloxanes for the first time. Three-blade propeller-like alignment of three phenyl groups in tri(2-butyl)triphenylcyclotrisiloxane induced a positive Cotton effect with (R)-2-butyl group, and a negative effect with (S)-2-butyl substituent.
