In many parts of the world, the only way to make germy water safe is by boiling, which consumes precious fuel, or by putting it out in the sun in a plastic bottle so ultraviolet rays will kill the microbes. But because UV rays carry only 4 percent of the sun’s total energy, the UV…
Experiments Demonstrate How Memristors Work
In experiments at two Department of Energy national labs – SLAC National Accelerator Laboratory and Lawrence Berkeley National Laboratory – scientists at Hewlett Packard Enterprise (HPE) have experimentally confirmed critical aspects of how a new type of microelectronic device, the memristor, works at an atomic scale. This result is an important step in designing these…
Frozen Gas Pushes Laser Light to New Boundaries
To observe something as small and fast as an electron rushing to form a chemical bond, you need a bright light with an incredibly small wavelength that comes in very fast pulses — just a few attoseconds, or billionths of a billionth of a second, long. Scientists figured out more than a decade ago how…
