Small, EarlyView.Fast 3D multiplane microscopy is combined with multiscale electrokinetic modeling to reconstruct nanoparticle motion around quadrupolar electrodes. This integrated optical‐computational framework reveals the full three‐dimensional structure of colloidal electrokinetic flows, including localized trapping, depletion layers, and complex vortical motion ...

On the free boundary problem for stationary compressible Navier-Stokes equations [PDF]
Communications in Mathematical Physics, 1990 The existence of rotationally symmetric solutions to a stationary free boundary value problem for the motion of a drop of a viscous compressible barotropic fluid is shown. An a priori estimate leads to the proof of the existence of Sobolev space solutions to a Navier-Stokes system in a prescribed domain.

Immobilized CuCl2/TiO2 photocatalysts for the selective oxidation of benzyl alcohol to benzaldehyde
Photochemistry and Photobiology, EarlyView.The photocatalytic aerobic oxidation of benzyl alcohol to benzaldehyde was investigated using free and alginate‐immobilized CuCl2 and/or TiO2 (P25) catalysts under UV irradiation. Immobilization enabled catalyst recovery and maintained high benzaldehyde selectivity but led to reduced activity due to internal oxygen diffusion limitations, which were ...

The Journal of Physiology, EarlyView.Abstract figure legend Non‐Newtonian modelling and GPEs for stroke risk in atrial fibrilation patients. Abstract Atrial fibrillation (AF) is the most common heart arrhythmia, linked to a five‐fold increase in stroke risk. The left atrial appendage (LAA), prone to blood stasis, is a common thrombus formation site in AF patients.

Decay rate of strong solutions to compressible Navier-Stokes-Poisson equations with external force
Electronic Journal of Differential Equations, 2019 In this article, we consider the three dimensional compressible Navier-Stokes-Poisson equations with the effect of external potential force. First, the stationary solution is established by solving a nonlinear elliptic system.

Plane-Parallel Laminar Flow of Viscous Fluid in the Transition Zone of the Inlet Section
Journal of Architectural and Engineering Research, 2023 A study was conducted to analyze how hydrodynamic parameters change in the entrance region of plane-parallel flow under stationary flow conditions, with an initial arbitrary distribution of velocities in the entrance section.

Direct Numerical Simulations of Inhalation in a 23‐Generation Lung Model
International Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 8, August 2026.The first direct numerical simulation of a 23‐bifurcation lung model is carried out. Fast and intense oscillations in the laminar flow are found in deep generations: their time scales are related to the upstream pressure fluctuations, and their intensity is related to upstream flow‐splitting fluctuations.
