Nanostructure-enhanced infrared spectroscopy
Nanophotonics, 2021 While infrared spectroscopy is a powerful technique that provides molecular information such as chemical constituents and chemical structures of analytes, it suffers from low absorption cross-section resulting in low sensitivity and poor signal-to-noise ...

Metallicities of Classical Cepheids in the Inner Galactic Disk
The Astrophysical Journal, 2023 Metallicity gradients refer to the sloped radial profiles of the metallicities of gas and stars and are commonly seen in disk galaxies. A well-defined metallicity gradient of the Galactic disk is observed particularly well with classical Cepheids, which ...
