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.

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.

Chiral Shock Waves

open access: yesPhysical Review Letters, 2017
We study the shock waves in relativistic chiral matter. We argue that the conventional Rankine-Hugoinot relations are modified due to the presence of chiral transport phenomena. We show that the entropy discontinuity in a weak shock wave is quadratic in the pressure discontinuity when the effect of chiral transport becomes sufficiently large.

Accurate equation of state of rhenium as pressure scale up to 130 GPa and 3200 K

open access: yesAIP Advances, 2022
The equations of states (EOSs) of inert metals are generally used as pressure scales in a high-pressure experiment. However, the thermodynamic model and the method used to constrain the parameters of the EOSs of these metals may cause pressure deviations
