Low cost, scalable water-splitting fuels the future hydrogen economy

06-Jun-2017

The "clean-energy economy" always seems a few steps away but never quite here. Fossil fuels still power transportation, heating and cooling, and manufacturing, but a team of scientists from Penn State and Florida State University have come one step closer to inexpensive, clean hydrogen fuel with ...

Subatomic microscopy key to building new classes of materials

01-Sep-2016

Researchers at Penn State and the Molecular Foundry at Lawrence Berkeley National Laboratory are pushing the limits of electron microscopy into the tens of picometer scale, a fraction of the size of a hydrogen atom. The ability to see at this subatomic level is crucial for designing new materials ...
