A Highly Stable-Output Kilohertz Femtosecond Hard X-ray Pulse Source for Ultrafast X-ray Diffraction

open access: yesApplied Sciences, 2022
Femtosecond hard X-ray pulses generated by laser-driven plasma sources are eminently suitable to probe structural dynamics due to the angstrom spatial resolution and sub-picosecond time resolution. However, the insufficient flux of X-ray photons and high

Exposure of zebra mussels to radial extracorporeal shock waves: implications for treatment of fracture nonunions

open access: yesJournal of Orthopaedic Surgery and Research, 2021
Background Radial extracorporeal shock wave therapy (rESWT) is an attractive, non-invasive therapy option to manage fracture nonunions of superficial bones, with a reported success rate of approximately 75%. Using zebra mussels (Dreissena polymorpha), we

All-Fiber Pulse-Train Optical Frequency-Domain Interferometer for Dynamic Absolute Distance Measurements of Vibration

open access: yesPhotonics, 2023
In this paper, we propose an all-fiber co-axial optical frequency-domain interferometer (OFDI) in a pulse-train mode with a sample rate of 9 kHz for measuring the vibrations in an internal structure without any contact.

Cherenkov-like shock waves associated with surpassing the light velocity barrier [PDF]

open access: yes, 1999
The effects arising from accelerated and decelerated motion of a point charge inside a medium are studied. The motion is manifestly relativistic and may be produced by a constant uniform electric field.

Flow visualisation of a normal shock impinging over a rounded contour bump in a Mach 1.3 free-stream [PDF]

open access: yes, 2016
An experimental study has been conducted to visualise the instantaneous streamwise and spanwise flow patterns of a normal shock wave impinging over a rounded contour bump in a Mach 1.3 free-stream.

Maximum self‐generated electric field induced by pyroelectricity of PZT 95/5

open access: yesInternational Journal of Ceramic Engineering & Science, 2021
Electric field induced by pyroelectric effect is often observed in the ferroelectric devices when they subject to temperature change. But the maximum value of ferroelectric field is still unknown.
