Resol-vegetable fibers composites
Journal of Applied Polymer Science, 2000 Vegetable fibers like cotton, sisal, and sugar cane bagasse have been used as reinforcement in a polymeric matrix. Because of its low cost and affinity with lignocellulosic fibers, a phenol-formaldehyde resin —resol— was selected as the matrix. Composites were prepared by compression molding.

Cteno‐Bot: An Untethered Metachronally Swimming Robot With Magnetoactive Propulsors
Advanced Intelligent Systems, EarlyView.We present Cteno‐bot, an untethered ctenophore‐inspired robot which swims using metachronally coordinated appendages. A single mechanism controls up to 216 magnetoactive propulsors via a dynamically varying magnetic field. We show that the swimming speed of the robot can be increased without a corresponding increase in power requirement, simply by ...
