Self-sustained biphasic catalytic particle turbulence | Nature Communications
Adding a little hydrofluoroether (HFE) organic solvent to a water based turbulent heater exchanger ups heat transfer 5x because the bubbling action assisted by the HFE pulls new cold liquid to the heat exchanger surface

ClearMotion - Home
Really active suspension, similar to the telescopic spoke smartwheels in Snowcrash, where active sensors map upcoming road surfaces and plan suspension travel to maximize adhesion. Perhaps now a logical consequence of autonomous driving sensor technology, which must map the local road environment anyways?

Bioinspired fibers change color when stretched — Harvard School of Engineering and Applied Sciences
Interesting photonic fiber research, which resembles dichroic materials, but because it is stretchable, allows active changing of the color by adjusting the bandgap. Possible uses in smart cloth showing deformation damage, or as a possible active camouflage textile system.

NASA - OCCAMS: Optically Controlled and Corrected Active Meta-material Space Structures
Wow, using photonic muscles embedded in a deployable thin film mirror, using a raster scanning laser to tweak the mirror as an active optical correction primary aperture mirror by using the muscles to deform the mirror. But, the concept suspiciously looks similar to a stealth radar deflection cone for spysats patented by Teledyne Ryan and allegedly used on Misty 1/2 and NROL-15.

Electromagnetic automobile suspension demonstrated
Hrm, net power consumption even with recovery in the actuator is a shame, makes it somewhat unattractive for EV, unless it's a variable affair from full active to off to in between. Say, sacrificing ride quality for range.

Engineer devises ways to improve gas mileage
I wonder if active flow control is an applicable technology to blades on wind turbines (considering parasitic power requirements to have a compressed air supply, and the difficulty of a highly variable airflow), with respect to things like the whale fin nodule vortex generator blade designs
