Wind-tunnel investigation of the effects of blade tip geometry on the interaction of torsional loads and performance for an articulated helicopter rotor [PDF]
The Langley transonic dynamics tunnel was used to determine the degree of correlation between rotor performance and the dynamic twist generated by changes in blade tip geometry using an articulated rotor with four different tip geometries at advance ...

Aramid Nanofiber Aerogels: Preparation, Modification, Composite Fabrication, and Applications
Different forms of aramid nanofibers (ANFs) and especially aerogels from them, offer a sustainable route to high‐performance biomimetic nanocomposites. Due to the cartilage‐like architecture, ANF‐based materials enable breakthroughs in energy, electromagnetic, biomedical, and water purification technologies.

Performance‐Recoverable Closed‐Loop Neuroprosthetic System
A self‐healing and stretchable bilayer (SSB) electrode with spontaneous performance recovery consists of a nanomembrane (closely packed aligned Pt‐coated Ag nanowires embedded in the self‐healing polymer) and a nanocomposite (Pt‐coated Ag flakes in the self‐healing polymer).

Synthetic Chromatophores for Color and Pattern Morphing Skins
Cephalopods use chromatophore organs (muscle‐actuated pigment sacs) to alter their skin color and pattern. Synthetic chromatophores, which closely mimic the mechano‐optical process found in cephalopods using stimuli‐responsive microscale hydrogel actuators, are reported.
