Catalysis stands as an indispensable cornerstone of modern society, underpinning the
production of over 80% of manufactured goods and driving over 90% of industrial chemical …

Single-molecule surface-enhanced Raman spectroscopy (SM-SERS) is an ultrahigh-
resolution spectroscopic method for directly obtaining the complex vibrational mode …

Picocavities are sub-nanometer-scale optical cavities recently found to trap light, which are
formed by single-atom defects on metallic facets. Here, we develop simple picocavity …

Molecular vibrations couple to visible light only weakly, have small mutual interactions, and
hence are often ignored for non-linear optics. Here we show the extreme confinement …

Transient bonds between molecules and metal surfaces underpin catalysis, bio/molecular
sensing, molecular electronics, and electrochemistry. Techniques aiming to characterize …

Nanoparticle-on-mirror plasmonic nanocavities, capable of extreme optical confinement and
enhancement, have triggered state-of-the-art progress in nanophotonics and development …

Understanding and manipulating quantum interference (QI) effects in single molecule
junction conductance can enable the design of molecular-scale devices. Here we …

Transient atomic protrusions in plasmonic nanocavities confine optical fields to sub-1-nm3
picocavities, allowing the optical interrogation of single molecules at room temperature …

High-temperature electrochemistry is widely used in many fields. However, real-time
observations and an in-depth understanding of the inside evolution of this system from an …

Efforts to characterize solid/liquid, solid/gas, liquid/gas, liquid/liquid, and liquid/gas
interfaces utilizing optical spectroscopies in the ultraviolet− visible (UV− vis), infrared (IR) …
