Low frequency lattice mode dynamics of cyclotrimethylene trinitramine (RDX) crystal studied by femtosecond time-resolved impulsive stimulated Raman scattering

open access: yesScientific Reports, 2023
The femtosecond time-resolved impulsive stimulated Raman scattering (fs-ISRS) has been performed to study the low frequency lattice mode dynamics of the RDX crystal.

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.

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

Effects of wave interaction on ignition and deflagration-to-detonation transition in ethylene/air mixtures behind a reflected shock [PDF]

open access: yes, 2021
Dynamics of ethylene autoignition and Deflagration-to-Detonation Transition (DDT) in a one-dimensional shock tube are numerically investigated using a skeletal chemistry including 10 species and 10 reactions. Different combustion modes are investigated through considering various premixed gas equivalence ratios (0.2 to 2.0) and incident shock wave Mach

Complexity and Shock Wave Geometries [PDF]

open access: yes, 2014
In this paper we refine a conjecture relating the time-dependent size of an Einstein-Rosen bridge (ERB) to the computational complexity of the dual quantum state. Our refinement states that the complexity is proportional to the spatial volume of the ERB.

On pressure impulse of a laser-induced underwater shock wave [PDF]

open access: yesJournal of Fluid Mechanics, 2015
We experimentally examine a laser-induced underwater shock wave paying special attention to the pressure impulse, the time integral of the pressure evolution.

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.

The Effects of the Exposure of Musculoskeletal Tissue to Extracorporeal Shock Waves

open access: yesBiomedicines, 2022
Extracorporeal shock wave therapy (ESWT) is a safe and effective treatment option for various pathologies of the musculoskeletal system. Many studies address the molecular and cellular mechanisms of action of ESWT.
