A new simple and scalable synthesis produces nanoparticle assemblies that can perform catalytic hydrogen sensing at room temperature for the first time.
Under high temperature conditions, hematite nanocrystals change shape to expose the (001) facet and attach to form one-dimensional chains regardless of their initial structure.
PNNL will provide technical resources and support to a national coalition of states and cities focused on implementing building performance standards to improve energy efficiency and reduce carbon emissions.
