Our Research Mission

Scientists in Brookhaven's Chemistry Division conduct basic and applied chemical research with an emphasis on new energy conversion pathways.

Primary research subjects include catalysis and electrocatalysis for sustainable fuel synthesis and use, solar energy conversion to fuels, fundamental gas and condensed phase molecular dynamics, radiation chemistry, and advanced chemical separations for energy applications. Fundamental studies of neutrino properties are also conducted in several international collaborations in nuclear and particle physics.

    "Molecular Cluster as Superatoms in Solid-State Chemistry"

    Traditional solid-state compounds are infinite crystalline arrays of densely packed atoms. The emergence of collective properties in structured clusters of atoms, which we term "superatoms", offers a new class of fundamental building blocks for assembling materials. The superatom concept has the potential to usher in a new era where materials are designed to have a specific function, rather than discovered by trial and error. To realize this concept, we are exploring the use of molecular clusters as superatomic building blocks, designing and synthesizing not only the molecular clusters but also the means by which they interact. In this presentation, I will show how the atomic control and the diversity afforded by our superatoms allows us to dictate the structure of the solids and control the interactions between the building blocks. I will discuss how collective properties emerge from these interactions by providing examples of magnetic phase transition, electrical transport and thermal energy transport.
