Chiral Plasmonic Metamaterials with Tunable Chirality
ACS Applied Materials & Interfaces, 2020Chiral 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, 2013In 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.

Chiral measure of chiral polyhedrons
ChiralityAbstractTo 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, 2012Using 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.

Chirality and Chiral Recognition
2009This 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.

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.

The furocoumarin 1,2-dihydro-2-(1,2-dihydroxyprop-2-yl)-8H-furo[2,3-h]benzopyran-8-one crystallizes from methanol-water as the monohydrate C(14)H(14)O(5).H(2)O. Both chiral centers have the S configuration. Both OH groups and both H atoms of the water molecule form intermolecular hydrogen bonds with O.O distances in the range 2.7686 (18)-2.8717 (18) A.

Twisting is a prevalent feature of long, thin vertical leaves; it has been shown that this twist contributes to the mechanical integrity of the leaf. We address the question as to how this twist comes about, and posit that it is a reflection of twist at a lower structural (geometric) level.

Chirality
ABSTRACTInclusion complexation, hydrogen bonds, π–π interaction, dipole–dipole interaction, and steric hindrance effect all contribute to the enantioseparation ability of cyclodextrin (CD) or CD derivatives. In this work, one native cationic CD chiral stationary phases (SHCDCSP) and four derivatized CD‐CSPs, namely, per(4‐trifluoromethyl ...
