Bioinspired high-power-density strong contractile hydrogel by programmable elastic recoil
Science Advances, 2020 Catapult-like hydrogel actuator delivers high contraction power. Stimuli-responsive hydrogels have large deformability but—when applied as actuators, smart switch, and artificial muscles—suffer from low work density due to low deliverable forces (~2 kPa)

Power density spectrum of NGC 5548 and the nature of its variability [PDF]
, 1998 We derive power density spectra in the optical and X-ray band in the timescale range from several years down to $\sim $ a day. We suggest that the optical power density spectrum consists of two separate components: long timescale variations and short ...
