Asymptotic Stability of Global Solutions to Non-isentropic Navier–Stokes Equations

Journal of Mathematics, 2023
This paper studies the asymptotic stability of global solutions of the three-dimensional nonisentropic compressible Navier–Stokes equations, where the initial data satisfy the “well-prepared” initial conditions, and the velocity field and temperature ...

Thermal Shielding and Vapor Transport Enhancement in MOF‐Enabled Membranes for Membrane Distillation

Advanced Science, EarlyView.
A metal–organic framework‐enabled membrane (MEM) with a hierarchical porous structure is developed for thermal‐efficient membrane distillation. By embedding ZIF‐8 onto PH nanofibers, the MEM achieves low thermal conductivity and significantly enhances vapor flux and thermal efficiency.

Navier-Stokes equations in the half-space in variable exponent spaces of Clifford-valued functions

Electronic Journal of Differential Equations, 2017
In this article, we study the steady generalized Navier-Stokes equations in a half-space in the setting of variable exponent spaces. We first establish variable exponent spaces of Clifford-valued functions in a half-space.

Well-posedness analysis of a stationary Navier–Stokes hemivariational inequality

Fixed Point Theory and Algorithms for Sciences and Engineering, 2021
This paper provides a well-posedness analysis for a hemivariational inequality of the stationary Navier-Stokes equations by arguments of convex minimization and the Banach fixed point.

Remarks on the “Onsager Singularity Theorem” for Leray–Hopf Weak Solutions: The Hölder Continuous Case

Mathematics, 2023
In this paper, we first present an overview of the results related to energy conservation in spaces of Hölder-continuous functions for weak solutions to the Euler and Navier–Stokes equations.

Super Time‐Resolved Tomography

Advanced Science, EarlyView.
A super time‐resolved tomography (STRT) approach is presented to reconstruct 4D X‐ray movies with an order‐of‐magnitude improvement in temporal resolution without sacrificing spatial resolution. By leveraging a physics‐informed deep learning algorithm that shares spatiotemporal features, STRT achieves high‐fidelity 3D reconstructions from sparse‐view ...

Photothermal Transport for Guiding Nanoparticles Through the Vitreous Humor

Advanced Science, EarlyView.
Nanosecond laser irradiation of the clinically approved dye indocyanine green (ICG) enables light‐guided nanoparticle transport within the vitreous humor. The combined use of ICG and pulsed laser illumination induces localized convection and thermophoresis, directing particles toward illuminated regions.

Enhanced Responsivity, Accuracy, and Stability of Aerosol Jet Printing via Mechanical Switching Valve Assisted Internal Shuttering

Advanced Science, EarlyView.
This work demonstrates ultra‐high ON‐OFF responsivity of AJP by mechanical switching valve assisted shuttering. The jet relaxation and ON‐OFF delay are substantially eliminated from greater than 35 s, maintaining patterning quality independent of the variations of printing parameters, permitting excellent process stability and universality.

Unconditional energy conservation and conditional regularity for the incompressible Navier-Stokes Maxwell system

Electronic Journal of Qualitative Theory of Differential Equations
In this paper, we study a hydrodynamic system modeling the evolution of a plasma subject to a self-induced electromagnetic Lorentz force in incompressible viscous fluids. The system consists of the Navier–Stokes equations coupled with a Maxwell equation.

Vortex Line Density in a Superfluid Turbulent Wake in the Zero Temperature Limit

Annalen der Physik, EarlyView.
The quasiclassical conjecture for quantum turbulence in a pure superfluid straightforwardly leads to the definition of the superfluid Reynolds number, Res=ud/κ$Re_s=ud/\kappa$, and suggests that the effective quantum viscosity should be of the order of the circulation quantum κ$\kappa$.
