Symmetry Breaking in Chiral Gold Nanoclusters by Ansa‐Metallamacrocycles Strain
AggregateChiral nanomaterials have recently stimulated significant interest in both fundamental research and practical applications (e.g., nanoprobes for biomolecular recognition). However, achieving chiral nanoclusters is still a major challenge.

Recent Progress of Chiral Mesoporous Silica Nanostructures: From Synthesis to Applications
MoleculesChiral mesoporous silica nanostructures (MSNs) have emerged as a cutting-edge material in nanotechnology. These nanostructures not only retain the tunable physicochemical properties of traditional MSNs—such as adjustable pore size, high surface area, and

Langmuir, 2017 More than half of all pharmaceuticals are chiral compounds. Although the enantiomers of chiral compounds have the same chemical structure, they can exhibit marked differences in physiological activity; therefore, it is important to remove the undesirable

Flexoelectrically Induced Polar Topology in Twisted SrTiO3 Membranes
Advanced Materials, EarlyView.Twisted SrTiO3 bilayers host polar vortices of flexoelectric origin, revealed through combined experiment and theory. By reconstructing polarization from the toroidal moment of strain gradients, the work establishes a 3D chiral state with broken inversion and mirror symmetries.

Broadband Circular Polarizers Constructed by Helix-like Chiral Metamaterials
, 2016 In this paper, a kind of helix-like chiral metamaterial, which can be realized with multiple conventional lithography or electron beam lithographic techniques, is proposed to achieve broadband bianisotropic optical response analogous to helical ...

Chiral pumping effect induced by rotating electric fields
, 2016 We propose an experimental setup using 3D Dirac semimetals to access a novel phenomenon induced by the chiral anomaly. We show that the combination of a magnetic field and a circularly polarized laser induces a finite charge density with an accompanying ...

Chiral Recognition by Oligosaccharides
Journal of Japan Oil Chemists' Society, 1994 Cyclodextrins (CDxs) are cyclic oligosaccharides produced by enzymatic reactions of starch. Since CDxs are composed of the D- (+) -glucopyranose units and have chiral cavities, CDxs can recognize the chiralities of guest molecules.Pyrene dimer as well as pamoic acid becomes optically active when these guest molecules are included in the γ-CDx cavity ...

Adaptive Twisting Metamaterials
Advanced Materials, EarlyView.This work introduces torque‐controlled twisting metamaterials as a transformative platform for adaptive crashworthiness. By combining multiscale predictive modeling with experimental validation on additively manufactured gyroids, it demonstrates tunable stiffness, collapse stress, and energy absorption.

Chiral anion recognition using calix[4]arene-based ureido receptors in a 1,3-alternate conformation
Beilstein Journal of Organic Chemistry, 2020 The introduction of chiral alkyl substituents into the lower rim of calix[4]arene immobilised in the 1,3-alternate conformation led to a system possessing a preorganised ureido cavity hemmed with chiral alkyl units in the near proximity.
