WebApr 13, 2024 · Metamaterial absorbers show great promise for applications in optical manipulation, photodetection, solar energy harvesting, and photocatalysis. In this work, we present a twisted stacked metamaterial design that serves as a plasmonic perfect absorber with polarization selectivity. Leveraging effective energy localization, the metamaterial … WebSep 12, 2006 · The plausibility of chiral selectivity during aminoacylation was supported by the recent observation that nonprotein, nonribozyme, RNA-directed aminoacylation of an RNA minihelix [that recapitulates the amino acid acceptor domain of, and is thought to be the progenitor of, modern transfer RNAs (ref. 5)] is chiral-selective, with three different ...

WebDec 30, 2024 · We demonstrate that the selective one-way routing of valley phonon states along the topological interface can be reversed by imposing the elastic spin metasource at different interface locations with opposite valley-spin correspondence. We unveil the physical mechanism of selective directionality as the elastic spin controlled chiral … WebJun 15, 2015 · In the present work it is demonstrated that secondary electrons from a substrate that are transmitted through a chiral overlayer cause enantiomeric selective chemistry in an adsorbed adlayer. We determine the quantum yields (QYs) for dissociation of (R)- or (S)-epichlorohydrin adsorbed on a chiral self-assembled layer of DNA on gold … bingo houses

WebNov 27, 2024 · Such chiral-selective absorption property is quite suitable for achieving coherent chiral-selective wavefront control for the unabsorbed circularly polarized incidence. Three coherent chiral metagratings are designed and experimentally characterized by further employing Pancharatnam–Berry phase method and multiplexed … WebHowever, current spin-selective metasurface designs have yet to mature into a practical method due to the limitations of single operating band or inefficient phase modulation. Herein, a novel chiral meta-atom is proposed, exhibiting spin-selective absorption/reflection functions for dual-orthogonal CP incident waves at three different operating ...
