Science Highlights

Scientists Gain Insight into Recycling Processes for Nuclear and Electronic Waste

The Hawaii and Alaska of chemistry, lanthanides and actinides are the elements that are always shown separately from the main block on the periodic table. Although they are split up from the more mainstream elements, they are important metals for applications such as nuclear power and magnets used in wind turbines and electric cars. Read more…

Unique Interface and Unexpected Behavior Help Explain How Heavy Metals Act 

Refining platinum, plutonium, or certain other metals often depends on how the metal behaves at liquid interfaces. The challenge? Scientists have limited ways to analyze the details of liquid interfaces. Now, researchers described in significant detail how water molecules surround a platinum-based ion. Their description includes an unexpectedly complex structure that forms on the liquid’s surface. Read more…
