Electron microscopy reveals new process for developing exotic metal alloys

Researchers from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have discovered a new way to produce high-entropy alloys (HEAs), at near-room temperatures. Their technique gives users much more control of the alloy’s crystal structure and overall morphology compared with existing methods, opening the door for a new paradigm of custom-made HEAs.

Analysis of 6,276 connectors for rooftop PV systems

Sandia National Labs researchers have created a new dataset on the rates and types of rooftop photovoltaic connector failures and published the first large-scale investigation of harvested PV connectors, drawing from a dataset of 6276 connectors from residential rooftop solar systems across the United States.
