Homochirality through Photon-Induced Melting of RNA/DNA: the Thermodynamic Dissipation Theory of the Origin of Life [PDF]

, 2010
The homochirality of the molecules of life has been a vexing problem with no generally accepted solution to date. Since a racemic mixture of chiral nucleotides frustrates the extension and replication of RNA and DNA, understanding the origin of ...

Inversion of Circularly Polarized Luminescence in Phenylethynyl-substituted Binaphthol Derivatives [PDF]

An inversion in the sign of circularly polarized luminescence (CPL) was achieved by strategically varying the substitution positions of phenylethynyl (PE) groups on the binaphthyl backbone while maintaining consistent axial chirality.

Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes

Advanced Functional Materials, EarlyView.
We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces
