报告摘要：

The chemical composition of atmospheric aerosols is a crucial factor in their contribution to air pollution and their impact on health. Strong laser fields offer a route for single particle chemical analysis, where molecular fragments are created in the laser interaction and spectroscopically identified. Under irradiation with light, the associated near-fields can induce, enhance, and control molecular adsorbate reactions on the nanoscale. So far, however, there is no simple method available to spatially resolve the near-field induced reaction yield on the surface of nanoparticles. Here, we close this gap by introducing reaction nanoscopy based on three-dimensional momentum resolved photoionization. We have developed a nanotarget reaction-microscopy based on recoil-ion-momentum spectroscopy (nanoTRIMS), which permits recording both ions and electrons from the interaction of light pulses with molecules on a nanoparticle surface in coincidence…
