New methods for ion cooling

Among the most important techniques developed in atomic physics over the past few years are methods that enable the storage and cooling of atoms and ions at temperatures just above absolute zero. Scientists from Bangalore and Mainz have now demonstrated in an experiment that captured ions can also be cooled through contact with cold atoms and may thus be stored in so-called ion traps in a stable condition for longer periods of time. This finding runs counter to predictions that ions would actually be heated through collisions with atoms.

New device hides, on cue, from infrared cameras

Now you see it, now you don't. A new device can absorb 99.75 percent of infrared light that shines on it. When activated, it appears black to infrared cameras.

Modeling the breaking points of metallic glasses

Metallic glass alloys (or liquid metals) are three times stronger than the best industrial steel, but can be molded into complex shapes with the same ease as plastic. These materials are highly resistant to scratching, denting, shattering and corrosion. Mathematical methods developed by scientists will help explain why liquid metals have wildly different breaking points.

Funneling the sun's energy

Engineers propose a new way of harnessing photons for electricity, with the potential for capturing a wider spectrum of solar energy.
