Seeing in Color at the Nanoscale

Berkeley Lab scientists develop a new nanotech tool to probe solar-energy conversion

If nanoscience were television, we’d be in the 1950s. Although scientists can make and manipulate nanoscale objects with increasingly awesome control, they are limited to black-and-white imagery for examining those objects. Information about nanoscale chemistry and interactions with light—the atomic-microscopy equivalent to color—is tantalizingly out of reach to all but the most persistent researchers.

But that may all change with the introduction of a new microscopy tool from researchers at the Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) that delivers exquisite chemical details with a resolution once thought impossible. The team developed their tool to investigate solar-to-electric energy conversion at its most fundamental level, but their invention promises to reveal new worlds of data to researchers in all walks of nanoscience.

From Cancer Research to Energy Storage, Berkeley Lab Scientist Takes on Big Challenges

*Rizia Bardhan, a postdoc at the Molecular Foundry, selected to Forbes’ ’30 under 30′ list*

On a typical day, Rizia Bardhan walks through the doors of Lawrence Berkeley National Laboratory’s Molecular Foundry and immerses herself in the tricky business of tweaking optical spectroscopy equipment to study phase transitions in metal hydrides.

It’s fair to say that what she does is difficult to grasp. Why she does it is easy: “I want to help solve big problems. That’s why I’m here,” she says. (more…)
