In Part 1, I regaled you all with the brief history behind the discovery of photochemical smog, and then proceeded to dazzle everyone with the intricacies of intake-related pollution controls. Here, ...

Furthermore, a prototype of the novel motor actuator has been developed according to the analysis and calculation results of the dynamic characteristics of 40.5-kV vacuum circuit breaker (VCB), and ...

Reaching nanometer precision in space isn’t just hard—it’s nearly impossible. But JWST’s flexure-driven actuators do it while surviving cryogenic temps, vacuum, and launch forces.

In this paper, we present miniaturized polydimethylsiloxane (PDMS)-based diaphragm dielectric elastomer actuators capable of out-of-plane displacement up to 25% of their diameter. This very large ...
