"Scientists have discovered a centrosymmetric crystal that behaves as though it is chiral – absorbing left- and right-handed circularly-polarized light differently. This counterintuitive finding, from researchers at Northwestern University and the University of Wisconsin-Madison in the US, could help in the development of new technologies that control light. Applications include brighter optical displays and improved sensors."

Chiral unveil “Bones” – the final chapter in their dark, cinematic trilogy

Irish alternative rock/metal band Chiral is set to release their highly anticipated new single and video, “Bones”, the final piece in a haunting trilogy that began with “In the Company of Wolves” and "I Bring Chaos.”

This gripping finale brings the story’s protagonist

(and we may have been looking at evidence of the #chiral inception of the universe, and the reason for its continuation here, imho)

"One explanation is that the universe was born rotating. That explanation agrees with theories such as black hole cosmology, which postulates that the entire universe is the interior of a black hole. But if the universe was indeed born rotating it means that the existing theories about the cosmos are incomplete."

`Herein we provide a theoretical treatment for this phenomenon, presenting an effective spin-Hamiltonian for helical molecules like DNA and density functional theory (DFT) results on amino acids that confirm the dependence of J-couplings on the choice of enantiomer. The connection between nuclear spin dynamics and #chirality could offer insights for #molecular sensing... These results establish NMR as a potential tool for #chiral discrimination without external agents.`

✨ #Innovation in #Chemical Data ✨

@BuchlerGmbh improves their search for #chiral #catalysts by integrating ontology terms from RXNO framework with our terminology service.
This promotes the FAIR principles terminology.

We are 😀 to contribute to this.

Why is posing a particular problem to outsiders or non technical people worth doing ? Simply because things come back from outside the box. If your in the box the tendency is to say why something won't work , that's just the way it is...and things will stay the way they are until enough people decide they shouldn't . It's a double edged sword of course but here's the thing-

#Chiral materials interact with light in very precise ways that are useful for building better displays, sensors and more powerful devices. However, #engineering properties such as chirality reliably at scale is still a significant challenge in nanotechnology.

"We show how, by sculpting the sub-optical-cycle oscillations of the driving #laser field, we can force one molecular #enantiomer to emit bright light while its mirror twin remains dark, thus reaching the ultimate efficiency limit of #chiral sensitivity via low-order #nonlinear light-matter interactions"

"We observe that oxygen #dynamics in #chiral environments (in particular its transport) depend on nuclear #spin, suggesting future applications for controlled #isotope separation to be used, for instance, in #NMR. To demonstrate the mechanism behind our findings, we formulate theoretical models based on a #nuclear-spin-enhanced switch between #electronic spin states."

#Chiral (left/right-handed) molecules are crucial to biochemistry. Light can distinguish between them but interacts too weakly, and boosting with #nanophotonics is not easy because it destroys chirality of EM fields. Typical solution is to design #nanostructures with highly chiral field that makes molecules absorb circularly polarised light differently. Here we find a much stronger effect where the molecules make nanostructures absorb light differently!

We had some super cool demonstrations of optical rotation (the rotation of the plane of polarisation of linearly polarised light as it passes through a #chiral molecule). Here’s light twisting through sucrose and fructose! 🌀🌈 I’ll paste the tweet to avoid overloading #ScienceMastodon’s servers https://twitter.com/jesswade/status/1593358274052644871
