We have developed the capability to elucidate interfacial reaction dynamics using an arguably unique combination of supersonic molecular beams combined with STM visualization. These capabilities have been implemented in order to reveal the complex spatiotemporal correlations that govern the oxidation of graphitic systems spanning atomic-, nano-, and meso-length scales. In this study, the 3 nm periodic moiré pattern of monolayer and bilayer graphene on Ru(0001) provides a diverse palette of potential scattering and binding sites at the interface for ground state atomic oxygen.

- The paper combines experimental and theoretical methods to investigate how water molecules (D2O) stick to cooled surfaces, using advanced techniques like supersonic molecular beam scattering and cryogenically cooled graphite.
- Three key experiments were conducted: measuring total D2O scattering to identify sticking onset, using He scattering for interface analysis during D2O adsorption, and performing time-of-flight measurements to observe energy exchange as surfaces heat up.
- The study incorporates molecular dynamics simulations to deepen understanding of energy transfer in gas-surface interactions, shedding light on how high-velocity gas flows interact with surfaces, ultimately influencing the process of gaseous condensation.
