CHIRAL PARTNERS IN A CHIRALLY BROKEN WORLD [PDF]

open access: yesInternational Journal of Modern Physics A, 2009
The isovector–vector and the isovector–axial-vector current are related by a chiral transformation. These currents can be called chiral partners at the fundamental level. In a world where chiral symmetry was not broken, the corresponding current-current correlators would show the same spectral information.

Chiral extensions of chiral polytopes

open access: yesDiscrete Mathematics, 2014
Given a chiral d-polytope K with regular facets, we describe a construction for a chiral (d + 1)-polytope P with facets isomorphic to K. Furthermore, P is finite whenever K is finite. We provide explicit examples of chiral 4-polytopes constructed in this way from chiral toroidal maps.

Quantum circuits to measure scalar spin chirality

open access: yesPhysical Review Research, 2023
The scalar spin chirality is a three-body physical observable that plays an outstanding role both in classical magnetism, characterizing non-co-planar spin textures, and in quantum magnetism, as an order parameter for chiral spin liquids.

Chiral Nanomaterials and Chiral Light [PDF]

open access: yesOptics and Photonics News, 2016
Advances in nanofabrication are expanding opportunities to exploit and customize the “handedness” of materials-and of light itself.

Chirality-Selected Coacervate by Chiral Gemini Surfactant

open access: yes, 2023
Chiral surfactants present opportunities to self-assemble into supramolecules with a chiral trait; however, the effects of stereochemistry on the formation of simple coacervates remain unclear.

28-Day Oral Chronic Toxicity Study of Arctigenin in Rats

open access: yesFrontiers in Pharmacology, 2018
Arctium lappa (burdock) is the most popular daily edible vegetable in China and Japan because of its general health tonic effects. Previous studies focused on the beneficial role of Arctigenin but neglected its potential side-effects and toxicities.

Direct observation of long-range chirality transfer in a self-assembled supramolecular monolayer at interface in situ

open access: yesNature Communications, 2022
Unravelling the mechanism of chirality transfer in supramolecular assemblies is important to understand the relationship between molecular chirality and supramolecular chirality.

Cu-Catalyzed Oxidative 3-Amination of Indoles via Formation of Indolyl(aryl)iodonium Imides Using o-Substituted (Diacetoxyiodo)arene as a High-Performance Hypervalent Iodine Compound

open access: yesMolecules, 2019
An oxidative 3-amination of indole derivatives using hypervalent iodine(III) and bissulfonimides, which proceeds via the formation of indolyl(aryl)iodonium imides, was developed.

Magnetic chirality

open access: yesnpj Quantum Materials, 2022
Chirality with all broken mirror symmetries matters ubiquitously from DNA functionality, vine climbing, to the piezoelectricity of quartz crystals. Magnetic chirality means chirality in spin-ordered states or (atomic-scale or mesoscopic) spin textures ...

Remarkable functions of sn-3 hydroxy and phosphocholine groups in 1,2-diacyl-sn-glycerolipids to induce clockwise (+)-helicity around the 1,2-diacyl moiety: Evidence from conformation analysis by 1H NMR spectroscopy

open access: yesBeilstein Journal of Organic Chemistry, 2017
Cell-membrane glycerolipids exhibit a common structural backbone of asymmetric 1,2-diacyl-sn-glycerol bearing polar head groups in the sn-3 position. In this study, the possible effects of sn-3 head groups on the helical conformational property around ...
