Programmable and Reversible 3D‐to‐3D Shape Transformation: Hierarchical Multimodal Morphing Based on Liquid Crystal Elastomers

open access: yesAdvanced Science, EarlyView.
Hierarchical multimodal 3D‐to‐3D shape morphing is achieved in liquid crystal elastomer‐elastomer bilayers via programmable mismatch strains. Combining pre‐stretch and thermal actuation enables reversible transformations with non‐zero Gaussian curvature, empowering over 30 complex configurations for biomimetic camouflage, adaptive robotics, and dynamic

Optical measurement of unducted fan flutter [PDF]

open access: yes
A nonintrusive optical method is described for flutter vibrations in unducted fan or propeller rotors and provides detailed spectral results for two flutter modes of a scaled unducted fan. The measurements were obtained in a high-speed wind tunnel.

Modulation of Aging Diseases via RAGE Targets: A Dietary Intervention Review

open access: yesAdvanced Science, EarlyView.
This paper analyzes RAGE ligand‐binding mechanisms and signaling, proposing intervention strategies targeting these interactions. It emphasizes dietary polyphenols, polysaccharides, and terpenoids delivered via functional foods for anti‐aging. These compounds offer long‐term, safe intervention through dietary supplementation, providing dual nutritional

Flutter Phenomenon in Flow Driven Energy Harvester–A Unified Theoretical Model for “Stiff” and “Flexible” Materials

open access: yesScientific Reports, 2016
Here, we report a stable and predictable aero-elastic motion in the flow-driven energy harvester, which is different from flapping and vortex-induced-vibration (VIV). A unified theoretical frame work that describes the flutter phenomenon observed in both

A preliminary study of the effects of vortex diffusers (winglets) on wing flutter [PDF]

open access: yes
Some experimental flutter results are presented for a simple, flat-plate wing model and for the same wing model equipped with two different upper surface vortex diffusers over the Mach number range from about 0.70 to 0.95.
