The Tiny Star Explosions Powering Moore’s Law

Cars That Think

At the time, about a decade ago, I was helping to refine a system for fabricating chips using extreme ultraviolet (EUV) light. To produce EUV light, we would focus an intense laser pulse onto 30-micrometer-wide droplets of tin flying through a chamber filled with low-density hydrogen.

Using Geofencing to Secure Electric Vehicles: A New Era in Location-Based Protection

Get Electric Vehicle

Cloud-Based Systems Cloud storage ensures that geofencing data, including location histories and alerts, are safely stored and accessible. For example, lights may turn on and garage doors open automatically when an EV arrives home. This is particularly useful for law enforcement or insurance purposes in case of theft.

SLAC, MIT, TRI researchers advance machine learning to accelerate battery development; insights on fast-charging

Green Car Congress

Then they took particles to Lawrence Berkeley National Laboratory’s Advanced Light Source to be examined with scanning X-ray transmission microscopy, which homes in on individual particles. An animation shows two contrasting views of how electrode particles release their stored lithium ions during battery charging. Resources.

Researchers observe hydrogen-oxygen reaction in ceria fuel cell; insights may improve efficiency

Green Car Congress

While the fuel cell was running, they applied high-brilliance X-rays produced by Berkeley Lab’s Advanced Light Source to illuminate the routes the oxygen ions took in the catalyst. The two blue balls would pick up an oxygen atom and release the electricity they stored. The blue balls are hydrogen atoms.
