We tested popular wideband O₂ controllers against lab-grade equipment to see how accurate their lambda readings really are ...
When [Electron Impressions] used a powerful ultrasonic array to project a narrow beam of sound toward a target, he described ...
During femtosecond laser fabrication, photons are mainly absorbed by electrons, and the subsequent energy transfer from electrons to ions is of picosecond order. Hence, lattice motion is negligible ...
