A New Way to Tune Emergent Magnetism

Perpendicular magnetic anisotropy (PMA)—where magnetic moments in a thin film preferentially point out of the plane of the film—is an emergent phenomenon of both fundamental and technological interest. A combination of x-ray techniques demonstrate how to tune PMA in transition-metal oxide multilayers. ... Read more »

A Path to a Game-Changing Battery Electrode

If you add more lithium to the positive electrode of a lithium-ion battery, it can store much more charge in the same amount of space, theoretically powering an electric car 30 to 50 percent farther between charges. But these lithium-rich cathodes quickly lose voltage, and years of research have not been able to pin down why—until now. ... Read more »

Ingredients for Life Revealed in Meteorites That Fell to Earth

Two wayward space rocks, which separately crashed to Earth in 1998 after circulating in our solar system’s asteroid belt for billions of years, share something else in common: the ingredients for life. They are the first meteorites found to contain both liquid water and a mix of complex organic compounds such as hydrocarbons and amino acids. ... Read more »

Studying Gas Mask Filters So People Can Breathe Easier

Scientists have put the x-ray spotlight on composite materials in respirators used by the military, police, and first responders. The results provide reassuring news about the effectiveness of current filters and provide fundamental information that could lead to more advanced gas masks as well as protective gear for civilian applications. ...
