Asteroid Disruption and Deflection Simulations for Multi-Modal Planetary Defense

Alexander N. Cohen, Philip Lubin, Darrel Robertson +7

Planetary defense from asteroids via deflective means alone does not offer viable solutions in terminal scenarios where there is little warning time before impact. The PI method of…

Optical and acoustic ground effects simulations from terminal defense asteroid disruption via the PI method

Brin Bailey, Alexander N. Cohen, Philip Lubin +5

Our simulations suggest that PI ("Pulverize It"), a NASA Phase II NIAC study, is an effective multi-modal approach for planetary defense that can operate in extremely short interdi…

Local B-site chemistry controls oxygen-vacancy energetics in Ca-Ce-Ti-Mn perovskites for thermochemical hydrogen production

Manish Kumar, Natalia Ali, Matthew D. Witman +5

Two-step thermochemical water splitting driven by concentrated solar heat is a scalable route to renewable hydrogen, but it requires oxides whose oxygen-vacancy formation energies…

Connecting Microseismicity to Lithology via a Model of Slip Avalanches

Ethan A. Mullen, Yanbo Wang, Jordan J. Sickle +4

Fluid injection into the earth's crust can induce small and frequent earthquakes in the subsurface. Predicting their sizes and temporal occurrences via statistical analysis is cruc…

Enabling topography-resolving structural dynamic contact simulation

Hendrik D. Linder, David A. Najera-Flores, Robert J. Kuether +1

Damping of structures and systems is often dominated by frictional dissipation in connections, the prediction of which remains a longstanding scientific challenge. Previous studies…
