Experimental Study on the Evolution of Single-Mode Interface Induced by Co-Directional Rarefaction and Shock Waves

气体物理
Developments of a single-mode light/heavy interface accelerated by co-directional rarefaction and shock waves were investigated. Induced by the rarefaction waves, the light/heavy perturbation amplitude experiences an oscillatory growth, which is referred

Optical spatial shock waves in nonlocal nonlinear media

Advances in Physics: X, 2019
Dispersive shock waves are fascinating phenomena occurring when nonlinearity overwhelms linear effects, such as dispersion and diffraction. Many features of shock waves are still under investigation, as the interplay with noninstantaneity in temporal ...

Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

Advanced Materials, EarlyView.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

Mechanically Spatio‐Chimeric Fibrin Assembly Enables Vascular‐Integrated Muscle Reconstruction for Volumetric Muscle Loss Repair

Advanced Materials, EarlyView.
SPARC (spatio‐chimeric, plasma‐based, anisotropic, and shear‐responsive construct) that integrates myogenic and vascular microenvironments within a single construct. The dual‐modulus matrix directs aligned myotube formation and endothelial network development, enabling a vascularized muscle implant that seamlessly anastomoses with host tissue and ...

Generation of shock waves in dense plasmas by high-intensity laser pulses

Nukleonika, 2015
When intense short-pulse laser beams (I > 1022 W/m2, τ < 20 ps) interact with high density plasmas, strong shock waves are launched. These shock waves may be generated by a range of processes, and the relative significance of the various mechanisms ...

Propagation of shock-wave/boundary-layer interaction unsteadiness in attached and separated flows

AIP Advances, 2020
The origin and propagation of low-frequency shock oscillation unsteadiness in the attached and separated flows are investigated. Wind tunnel experiments are performed in an isolator at Mach 1.85 and 2.7 with three types of upstream wedges, generating ...

Controlling Radiative Phonons in the van der Waals Ferroelectric NbOI2

Advanced Materials, EarlyView.
Using a simple mirror geometry, this work demonstrates local‐density‐of‐optical‐states control of THz phonon emission in van der Waals ferroelectric NbOI2. By engineering the photonic environment, the phonon Q‐factor, linewidth, peak frequency, and emission intensity are reversibly tuned by over an order of magnitude, revealing radiative phonons as ...

Low-frequency dissipative dust-acoustic waves in plasmas having superthermal two-electron temperature: Implications for solitons and shock waves in Saturn’s magnetosphere

Journal of Low Frequency Noise, Vibration and Active Control
This study investigates the nonlinear dynamics of low-frequency dust-acoustic waves in a viscous plasma environment. It emphasizes the formation and behavior of shock and solitary waves, considering the interplay between inertial fluid dust particles and
