Numerical simulation model of a reciprocating seal based on the mixed-lubrication theory

open access: yesThe Journal of Engineering, 2018
Based on the mixed-lubrication theory, a numerical simulation model of a reciprocating seal is established. The model includes finite element, fluid mechanics, contact mechanics and deformation mechanics analyses.

UTact: Underwater Vision‐Based Tactile Sensor with Geometry Reconstruction and Contact Force Estimation

open access: yesAdvanced Robotics Research, EarlyView.
Embedded flexible sensing technologies advance underwater soft robotics, yet most systems still suffer from hysteresis and limited perceptiveness. Instead, vision‐based tactile sensors provide reliable and rapid feedback essential for complex underwater tasks.

Multimodal Locomotion in Insect‐Inspired Microrobots: A Review of Strategies for Aerial, Surface, Aquatic, and Interfacial Motion

open access: yesAdvanced Robotics Research, EarlyView.
This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Hydrodynamic modelling of hydrostatic magnesium extrusion [PDF]

open access: yes, 2006
Wilson’s hydrodynamic model of the hydrostatic extrusion process is extended to meet the geometry found on residual billets. The transition from inlet\ud to work zone of the process is not considered sharp as in the model of Wilson but as a rounded edge,

Simulating (electro)hydrodynamic effects in colloidal dispersions: smoothed profile method

open access: yes, 2008
Previously, we have proposed a direct simulation scheme for colloidal dispersions in a Newtonian solvent [Phys.Rev.E 71,036707 (2005)]. An improved formulation called the ``Smoothed Profile (SP) method'' is presented here in which simultaneous time ...

A Versatile Three Dimensional Traction Force Microscopy Framework for Uncovering the Mechanics of Bio‐Adhesion

open access: yesAdvanced Science, EarlyView.
This study introduces a versatile platform for quantifying three dimensional traction forces at bio‐adhesive interfaces. Integrating in situ stereo‐digital image correlation with finite element simulations allows for precise measurement of microscale displacements and traction forces in both dry and wet conditions.

Trajectory analysis for non-Brownian inertial suspensions in simple shear flow [PDF]

open access: yes, 2006
We analyse pair trajectories of equal-sized spherical particles in simple shear flow for small but finite Stokes numbers. The Stokes number, $\mbox{\textit{St}} \,{=}\, \dot{\gamma} \tau_p$, is a dimensionless measure of particle inertia; here, $\tau_p ...

Nanozyme‐Integrated Hydrogel Targeting AGEs for Diabetic Osteoarthritis Therapy

open access: yesAdvanced Science, EarlyView.
A nanozyme–integrated hydrogel (PTC‐MP) exhibiting with mild photothermal effects is constructed, and a “3R” (restrain‐restore‐reinforce) strategy is proposed for diabetic osteoarthritis (DOA) treatment based on advanced glycation end products (AGEs) targeting.
