Nanostructures wetting evaluation using ultra high frequency ultrasound
Oxide-based Materials and Devices XIII, 2022 Ultrasounds are a great tool for defects detection particularly for optically non-transparent materials. Hence, working at very high frequency (#GHz) allows the detection of nanoscale contact defects at the interface between two materials and especially in the presence of air, which has negligible acoustic impedance, making it possible to achieve very ...

Pressure estimation of ultra-high frequency ultrasound using gas vesicles. [PDF]
J Acoust Soc AmAcoustic microscopy uses ultra-high frequency (UHF) ultrasound transducers over 80 MHz to perform high-resolution imaging. The pressure output of these transducers is unknown, as commercial calibrated hydrophones can measure pressure for transducers with frequencies only up to 80 MHz.
