Observation of shock-induced protein crystal damage during megahertz serial femtosecond crystallography

open access: yesPhysical Review Research, 2021
Shock waves launched by x-ray pulses in sample-carrying liquid jets may affect protein crystallography data collected at MHz repetition rate x-ray free-electron laser (XFEL) facilities, by damaging the crystals before they are probed. We investigated the

Enhanced shock scattering histotripsy with pseudo-monopolar ultrasound pulses [PDF]

open access: yesThe Journal of the Acoustical Society of America, 2018
Shock scattering histotripsy (SSH) involves a complex interaction between positive and negative phases of an acoustic burst to initiate a robust cavitation bubble cloud. To more precisely study these effects and optimize SSH therapy, we constructed a frequency compounding transducer to generate pseudo-monopolar ultrasound pulses.
