ANN ARBOR — In work that unmasks some of the magic behind memristors and “resistive random access memory,” or RRAM—cutting-edge computer components that combine logic and memory functions—researchers have shown that the metal particles in memristors don’t stay put as previously thought.

The findings have broad implications for the semiconductor industry and beyond. They show, for the first time, exactly how some memristors remember. (more…)

COLUMBUS, Ohio – Using a new ultrafast camera, researchers have recorded the first real-time image of two atoms vibrating in a molecule.

Key to the experiment, which appears in this week’s issue of the journal Nature, is the researchers’ use of the energy of a molecule’s own electron as a kind of “flash bulb” to illuminate the molecular motion. (more…)
