Tracking chirality in photoelectron circular dichroism

Physical Review Research
In photoelectron circular dichroism (PECD) it is generally difficult to trace how and when the chirality of the molecule is imprinted onto the photoelectron.

Spin-Selective Transmission and Devisable Chirality in Two-Layer Metasurfaces

Scientific Reports, 2017
Chirality is a nearly ubiquitous natural phenomenon. Its minute presence in most naturally occurring materials makes it incredibly difficult to detect.

Controllable switching of vortex chirality in magnetic nanodisks by a field pulse

, 2007
We propose a way of fast switching the chirality in a magnetic nanodisk by applying a field pulse. To break the symmetry with respect to clockwise or counterclockwise chirality a mask is added by which an inhomogeneous field influences the vortex state ...

A Cu‐Based Near‐IR Active MOF with an Ion‐Pair Guest Exhibiting Versatile and Selective Gas‐Solid Reactivity

Advanced Materials, EarlyView.
The new Cu‐containing MOF (Me2NH2)(CuICl2)@[Cu4(INA)4Cl2O]·1.5dmf (3) contains a cation and an anion as guests and shows UV‐near‐mid‐IR absorption and near‐IR emission. MOF 3 shows gas‐solid reactivity in the presence of NH3 and HCOOH to yield two new 3D MOF.

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.

Cooperative expression of atomic chirality in inorganic nanostructures

Nature Communications, 2017
Cooperative chirality is common in organic and biomolecular systems but is rarely explored in inorganic materials. Here, the authors combine synthesis and theory to uncover cooperative chirality in inorganic nanocrystals, arising from the interplay of ...

Ground-state phase diagram of the Kondo lattice model on triangular-to-kagome lattices

, 2012
We investigate the ground-state phase diagram of the Kondo lattice model with classical localized spins on triangular-to-kagome lattices by using a variational calculation.

Epithelial cell chirality emerges through the dynamic concentric pattern of actomyosin cytoskeleton

eLife
The chirality of tissues and organs is essential for their proper function and development. Tissue-level chirality derives from the chirality of individual cells that comprise the tissue, and cellular chirality is considered to emerge through the ...

Symmetry restrictions in chirality dependence of physical properties of single wall nanotubes

, 2005
We investigate the chirality dependence of physical properties of nanotubes which are wrapped by the planar hexagonal lattice including graphite and boron nitride sheet, and reveal its symmetry origin.
