The Army Research Laboratory's new nanomaterial paves the way for efficient and green energy solutions.


Like many great scientific advancements, the U.S. Army Research Laboratory's (ARL) new nanomaterial was invented by accident. Materials engineers at ARL on Aberdeen Proving Ground, Maryland, were trying to engineer a nanostructured aluminum alloy in January 2017 when, during polishing and hardness testing, they discovered the aluminum powder was disappearing--it was reacting with the water used in the polishing process to create hydrogen. While the discovery surprised ARL scientists, they knew they had come across something quite extraordinary.
