A Regularity Criterion for the Navier-Stokes Equations in the Multiplier Spaces

Abstract and Applied Analysis, 2012
We exhibit a regularity condition concerning the pressure gradient for the Navier-Stokes equations in a special class. It is shown that if the pressure gradient belongs to 𝐿2/(2−𝑟)̇𝐻((0,𝑇);ℳ(𝑟(ℝ3̇𝐻)→−𝑟(ℝ3))), where ̇𝐻ℳ(𝑟(ℝ3̇𝐻)→−𝑟(ℝ3)) is the multipliers ...

3D Locomotion of Surface‐Rolling Microrobots: A Trade‐off between Hydrodynamic Wall and Gravitational Effects

Advanced Intelligent Systems, EarlyView.
This study investigates 3D locomotion of surface‐rolling microrobots, revealing a trade‐off between hydrodynamic wall effects and gravity. Through experiments and simulations, it explores how robot size, inclination angle, actuation frequency, and surface microtopography affect the 3D locomotion.

Existence and regularity of solutions to the Leray-alpha model with Navier slip boundary conditions

Electronic Journal of Differential Equations, 2016
We establish the existence and regularity of a unique weak solution to turbulent flows in a bounded domain $\Omega\subset\mathbb R^3$ governed by the Leray-$\alpha$ model with Navier slip boundary condition for the velocity. Furthermore, we show that

BOPHY Dyes Bearing Arylsulfenyl Moieties as Highly Efficient Triplet Photosensitizers

Asian Journal of Organic Chemistry, EarlyView.
A new set of symmetric BOPHY dyes has been successfully applied in photoinduced processes acting as triplet photosensitizers. They have been used not only in bimolecular systems for photon upconversion based on triplet‐triplet annihilation but also in generating singlet oxygen for oxidation processes.
