Simmons Recognized at DOE Merit Review
PNNL materials scientist Kevin Simmons is part of a collaboration that was recognized for work in hydrogen safety, codes and standards recently at the DOE Hydrogen and Fuel Cells Program annual merit review and peer evaluation.
Identifying What Controls Reactivity in Concentrated Alkaline Aluminate Solutions
Hydrogen bonding and proton transfer control the identity and reactivity of molecules in highly concentrated and alkaline aluminate solutions.
Grain Boundary-Rich Network Structure Induces High Catalytic Activity
A new simple and scalable synthesis produces nanoparticle assemblies that can perform catalytic hydrogen sensing at room temperature for the first time.
The Contradictory Catalyst
Using a natural catalyst from bacteria for inspiration, researchers have now reported the fastest synthetic catalysts to date for hydrogen production-- producing 45 million hydrogen molecules per second.
Tracking Mechanisms of Crystallization in Real Time
iDREAM research shows that concentrated electrolytes in solution affect hydrogen bonding, ion interactions, and coordination geometries in currently unpredictable ways.
Advantage: Water
When water comes in for a landing on the common catalyst titanium oxide, it splits into hydroxyls just under half the time. Water's oxygen and hydrogen atoms shift back and forth between existing as water or hydroxyls, and water has the sli
