Magic Gap Ratio

A defining experimental signature of a crossover in the strength of the pairing interactions has been discovered in high temperature superconductors.

BCS (left) refers to a conventional Bardeen-Schrieffer-Cooper state (i.e. weak pairing state) found in most superconductors, while BEC (right) refers to the strong pairing limit of a Bose-Einstein Condensate.

Zeolite Catalysts

Ultra-high magnetic field NMR spectroscopy provides details on the structures and proximities of zeolite catalysts that are widely used in modern industrial processes.

    17O Labeling Reveals Paired Active Sites in Zeolite Catalysts

    Zeolite catalysts are critical to generating the molecules that provide the building blocks of society’s energy and materials needs. Discerning a clear atomic-level picture of the active sites remains challenging for most current technologies, but here we show that solid-state nuclear magnetic resonance (ssNMR) methods coupled with ultra-high magnetic field instruments, can and has provided extremely useful information for catalyst development.

    Pavement Sealant Leaches Environmental Contaminants

    New research shows that high concentrations of polycyclic aromatic hydrocarbons (PAHs) found in coal tar pavement sealants are oxidized into toxic, water-soluble compounds by sunlight and subsequently washed into the environment by rainwater, polluting natural water systems, negatively impacting marine ecosystems and public health.
