Abstract: Abstract Lithiation of M-C2H2 results significant enhancement of second-hyperpolarizability. The negatively polarized π-surface of C2Li2 raises the molecular orbital energies which strongly favours both metal-HOMO to ligand-LUMO and ligand-HOMO to metal-LUMO charge transfer interactions. Due… read more here.

Abstract: Abstract Metasurfaces have become significant platforms for optical manipulation, yet unlocking their full potential for nonlinear optics requires novel mechanisms to control and enable frequency conversion processes. This study demonstrates how structural dimerization in plasmonic… read more here.
