Compact batteries enhanced by spontaneous silver matrix formations
The formation of a highly conductive silver matrix inside an otherwise poorly performing battery enhances its efficiency and offers new potential applications. Scientists used x-rays to see where, when, and how these nanoscale 'bridges' emerge and develop new material designs and optimization techniques.

Microscopy reveals how atom-high steps impede oxidation of metal surfaces
A new study reveals that certain features of metal surfaces can stop the process of oxidation in its tracks. The findings could be relevant to understanding and perhaps controlling oxidation in a wide range of materials -- from catalysts to the superalloys used in jet engine turbines and the oxides in microelectronics.

Ultrafast imaging of complex systems in 3-D at near atomic resolution nears
It is becoming possible to image complex systems in 3-D with near-atomic resolution on ultrafast timescales using extremely intense X-ray free-electron laser pulses. One important step toward ultrafast imaging of samples with a single X-ray shot is understanding the interaction of extremely brilliant and intense X-ray pulses with the sample, including ionization rates.

NREL compares state solar policies to determine equation for solar market success
Analysts at the Energy Department's National Renewable Energy Laboratory have used statistical analyses and detailed case studies to better understand why solar market policies in certain states are more successful. Their findings indicate that while no standard formula for solar implementation exists, a combination of foundational policies and localized strategies can increase solar photovoltaic installations in any state.
