Shockwaves in Supernovae: New Implications on the Diffuse Supernova Neutrino Background

, 2009
We investigate shock wave effects upon the diffuse supernova neutrino background using dynamic profiles taken from hydrodynamical simulations and calculating the neutrino evolution in three flavors with the S-matrix formalism. We show that the shock wave

Drug‐Free Thrombolysis Mediated by Physically Activated Micro/Nanoparticles

Advanced Functional Materials, EarlyView.
Overview of particle‐mediated thrombolytic effects (thermal, mechanical, and chemical) and their activating physical stimuli (light, ultrasound, and magnetic field) in drug‐free thrombolysis. ABSTRACT Thrombus‐associated disorders rank among the world's leading causes of death, with ischemic heart disease and stroke as the main contributors.

Thermodynamically consistent phase-field model for pressure-induced multiphase phase transformation of metals under intensive dynamic loading

Journal of Materials Research and Technology
Understanding the pressured-induced multiphase phase transformation (MPT) of metals at high strain rate is of great technical and scientific interest. Despite of several decades of studies, the pressured-induced MPT of metals at high strain rate is far ...

Inner core composition paradox revealed by sound velocities of Fe and Fe-Si alloy

Nature Communications, 2022
The origin of the observed low shear wave velocity in the solid inner core is unclear. Here, the authors report shear wave velocities of iron and iron-silicon alloy under Earth’s core conditions by shock compression and find that neither the effect of ...

Computational Models of Material Interfaces for the Study of Extracorporeal Shock Wave Therapy

, 2012
Extracorporeal Shock Wave Therapy (ESWT) is a noninvasive treatment for a variety of musculoskeletal ailments. A shock wave is generated in water and then focused using an acoustic lens or reflector so the energy of the wave is concentrated in a small ...

Elastic-plastic coupled α→ω phase transformation of zirconium under shock loading: experiments and non-hydrostatic thermodynamic-based modeling

Journal of Materials Research and Technology
Modeling the martensitic transformation of solid materials under shock loading is still an unsolved problem. One of the key challenges is the effect of shear stress and elastoplastic coupling on the dynamic response.
