Direct Numerical Simulation of Gas–Particle Flows with Particle–Wall Collisions Using the Immersed Boundary Method

Applied Sciences, 2018
We investigated particulate flows by coupling simulations of the three-dimensional incompressible Navier–Stokes equation with the immersed boundary method (IBM). The results obtained from the two-way coupled simulation were compared with those of the one-

Photo‐Gated Corona Microfluidics

Advanced Science, EarlyView.
Photo‐gated corona microfluidics decouples optical programming from electric‐field actuation to enable reconfigurable manipulation on open, electrode‐pattern‐free surfaces. Near‐infrared irradiation locally melts paraffin, creating a reversible charge‐relaxation pathway that reconstructs the electric field.

Alternating Shear Force of Respiration Regulates Cell Interactions of Fibroblasts and Macrophages to Promote Soft Tissue Integration of Chest Wall Polyetheretherketone Implants

Advanced Science, EarlyView.
Given that PEEK chest wall implants induce shear force at the soft tissue‐implant interface due to respiratory motion in the early in vivo post‐implantation stage. We confirmed that this mechanical stimulus triggers the PIEZO1/ITGB1/YAP1 signalling axis in L929 and the STAT6/p‐STAT6 pathway in RAW264.7, which in turn mediates adhesion and migration of ...

MOF‐Derived Cu‐TiO2/Alginate Micromotors for Buoyancy‐Regulated 3D Motion

Advanced Science, EarlyView.
In this work, cyanobacteria‐inspired sodium alginate (SA)/Cu‐TiO2/Fe3O4 hydrogel micromotors generate and encapsulate O2 microvesicles upon light irradiation, enabling buoyancy‐mediated Z‐axis upward migration and surface enrichment at the light‐exposed water‐air surface.

Curvature Dependent Energy of Surface Curves in Minkowski Space

International Journal of Analysis and Applications, 2018
In this paper, we firstly introduce kinematics properties of the moving particle lying on a surface S. We assume that the particle corresponds to a different type of surface curves such that they are characterized by using the Darboux vector field W in ...

Manifest color-kinematics duality for point particles interacting with self-dual fields

Journal of High Energy Physics
We find that point particles interacting with a self-dual Yang-Mills field and self-dual gravity manifestly satisfy color-kinematics duality at the level of action. In a similar way color-kinematics duality also holds for a scalar field minimally coupled

Freestanding Hierarchical‐Porous BCZT Thin Films Enable Efficient Ultrasonic Energy Harvesting in Soft Tissue

Advanced Science, EarlyView.
Freestanding hierarchical‐porous BCZT thin films integrate a compliant porous surface with a dense piezoceramic backbone to balance mechanical reliability, voltage sensitivity, and acoustic coupling. The films enable stable wearable pulse‐wave monitoring and enhanced tissue‐coupled ultrasonic energy harvesting, offering a promising route toward soft ...
