X-ray Driven Trihydrogen Formation on Silica Nanosurfaces
Samuel Sahel-Schackis, Adam Summers, Ritika Dagar +29
The trihydrogen cation () initiates the ion-molecule reactions that build molecular complexity in interstellar space. Whether its canonical formation reaction, $\ma…
Effect of Burn Parameters on PAH Emissions at Conditions Relevant for Prescribed Fires
Karl Töpperwien, Guillaume Vignat, Alexandra J. Feinberg +10
Wildfire smoke is a health hazard as it contains a mixture of carcinogenic volatile compounds and fine particulate matter. In particular, exposure to polycyclic aromatic hydrocarbo…
Catalysis in Extreme Field Environments: The Case of Strongly Ionized Nanoparticle Surfaces
Thomas M. Linker, Ritika Dagar, Alexandra Feinberg +8
High electric fields can significantly alter catalytic environments and the resultant chemical processes. Such fields arise naturally in biological systems but can also be artifici…
Tracking Surface Charge Dynamics on Single Nanoparticles
Ritika Dagar, Wenbin Zhang, Philipp Rosenberger +16
Surface charges play a fundamental role in physics and chemistry, particularly in shaping the catalytic properties of nanomaterials. Tracking nanoscale surface charge dynamics rema…
