1. Comments on "Molecular Chirality in Classical Spacetime: Solving the Controversy about the Spinning Cone Model of Rotating Molecules".

Author

Barron LD and Cintas P

Abstract

A recent mathematical analysis by Michel Petijean aimed at solving the Barron/Mislow controversy concerning the chirality or otherwise of a non-translating spinning cone concluded that both are right: the controversy is a matter of an arbitrary choice of a conversion factor. This reassessment highlights the different physicochemical properties of a stationary spinning cone and a chiral molecule and concludes that Petitjean's analysis is misleading., (© 2020 Wiley-VCH GmbH.)

2. Disposable Plasmonics: Plastic Templated Plasmonic Metamaterials with Tunable Chirality.

Author

Karimullah AS, Jack C, Tullius R, Rotello VM, Cooke G, Gadegaard N, Barron LD, and Kadodwala M

Abstract

Development of low-cost disposable plasmonic substrates is vital for the applicability of plasmonic sensing. Such devices can be made using injection-molded templates to create plasmonic films. The elements of these plasmonic films are hybrid nanostructures composed of inverse and solid structures. Tuning the modal coupling between the two allows optimization of the optical properties for nanophotonic applications., (© 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.)

3. Determination of the helical screw sense and side-group chirality of a synthetic chiral polymer from Raman optical activity.

Abstract

Splitting it up: excellent agreement between the experimental and the quantum-chemically simulated Raman optical activity (ROA) spectrum of (+)-poly(trityl methacrylate) shows that the polymer backbone adopts a left-handed helical conformation while the trityl side groups display a left-handed propeller conformation. Thus ROA can be used to determine the complete structure of synthetic chiral polymers in solution., (Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.)
