Spatially Resolved Observation of Ferroelectric‐to‐Paraelectric Phase Transition in a Two‐Dimensional Halide Perovskite

open access: yesAdvanced Materials, EarlyView.
Temperature‐dependent nanoscale ferroelectric domain evolution and the ferroelectric‐to‐paraelectric phase transition in 2D halide perovskites is visualized using piezoresponse force microscopy. The phase transition initiates locally below the Curie temperature and progressively propagates as paraelectric regions expand.

Research of detonation products of RDX/Al from the perspective of composition

open access: yesDefence Technology, 2023
Aluminized explosives exhibit excellent performance because the oxidation of aluminum (Al) powders enhances the pressure and temperature of detonation products. However, the equation of state (EOS) of detonation products has not been understood well.

Exposure of zebra mussels to extracorporeal shock waves demonstrates formation of new mineralized tissue inside and outside the focus zone

open access: yesBiology Open, 2018
The success rate of extracorporeal shock wave therapy (ESWT) for fracture nonunions in human medicine (i.e. radiographic union at 6 months after ESWT) is only approximately 75%.

Singular shock waves in interactions [PDF]

open access: yesQuarterly of Applied Mathematics, 2008
n a number of papers it was shown that there are one-dimensional systems such that they contain solutions with, so called, overcompressive singular shock waves besides the usual elementary waves (shock and rarefaction ones as well as contact discontinuities).

A Dynamic Spike Sorter for Multiscale Nanoelectrode Array Recordings

open access: yesAdvanced Materials Interfaces, EarlyView.
This work introduces a dynamic spike sorting pipeline that isolates diverse electrical signals from nanoelectrode arrays. Using biophysical simulations to calibrate signal processing, the approach reveals relationships between action potentials and membrane fluctuations, advancing the understanding of neuronal network excitability.

Near-full density enabled excellent dynamic mechanical behavior in additively manufactured 316L stainless steels

open access: yesMaterials & Design
Mechanical properties of additively manufactured alloys are momentously affected by the fabrication defects, thus limiting their applications in extreme conditions.

On shock waves in solids

open access: yesDiscrete & Continuous Dynamical Systems - B, 2007
This paper describes some recent theoretical results pertaining to the experimentally-observed relation between the speed of a shock wave in a solid and the particle velocity immediately behind the shock. The new feature in the present analysis is the assumption that compressive strains are limited by a materially-determined critical value, and ...
