Vortex-induced vibrations of a non-linearly supported rigid cylinder
, 2008 Vortex-Induced Vibrations (VIV) are a complex fluid-structure interaction problem.VIV are particularly strong for low-mass structures subject to a low damping, asencountered in the offshore industry, in which structures experiencing VIV can alsobe ...

Advanced Science, EarlyView.This work proposed a pollen‐enhanced bionic mechanoreceptor based on ionic convection. Leveraging the ion anchoring effect of the pollen particle, the output performance could be ∼12 times higher than the original state. By employing deep learning models as AI brains, the feasibility of a sensory‐augmented prosthesis consisting of a pollen‐enhanced ...

Advanced Science, EarlyView.We proposed a method based on the piezoelectric effect and fabricated an implant abutment on the basis of piezoelectric ceramic. Under physiological occlusal pressure, the oral motion‐powered smart dental implant abutments interacted with water and oxygen, promoting the formation of reactive oxygen species and achieving a synergistic and highly ...

Advanced Science, EarlyView.Facet‐engineered PVP‐capped CuFeSe2 nanocrystals exhibit potent, selective antifungal activity by strongly binding cell‐wall mannan, enabling vacuolar entry and organelle disruption. High‐index facets show superior mannan affinity, validated by theoretical calculations and experiments. CFS‐P induces vacuolar cavitation, mitochondrial abnormalities, and

Nonlinear vortex induced vibrations of inclined marine risers
, 2017 In this paper, we study the nonlinear dynamics of statically deflected offshore structures undergoing vortex induced vibrations. We consider inclined risers that have catenary-like profiles where the riser structure is modelled as an Euler-Bernoulli beam

Controlling parameter for wave types of long flexible cable undergoing vortex-induced vibration
, 2010 Submerged floating tunnel (SFT) is a popular concept of crossing waterways. The failure of the cable may occur due to vortex-induced-vibration (VIV), and the stability of the cable is crucial to the safety of the entire tunnel.
