  • Beratan and Collaborators show how DNA sequences turn molecules into electron highways

    A theoretical-experiemental collaboration between David Beratan’s group at Duke University and Nongjian Tao’s group at Arizona State University   has established and validated an approach to control the wave-like characteristics of electrons as they move through DNA.  A paper just posted online at Nature Ch

  • Breakthrough in Nanoelectronics: Design of Robust Molecular Switches

    An article in Science by Prof. Agostino Migliore and collaborators reports the design of robust (opto)electronicmolecular switches. The experiments demonstrate reversible, stable and reproducible electrical switching of single molecules linked to graphene electrodes. The theoretical analysis reveals the chemical-physical underpinnings of photoinduced and temperature-dependent mechanisms for the observed switching. This work provides unambiguous evidence that molecules with suitable electronic properties and engineered contacts can be key components for future nanoelectronics.

  • Charbonneau Lab Makes Breakthrough in Periodic Microphases

    Yuan Zhuang from the Charbonneau group has recently made a breakthrough in the description of periodic microphases. This advance enables the determination of phase diagrams for models that can form cluster crystals, double gyroid, lamellae, and other complex mesoscale assemblies. The results appear in Physical Review Letters.

  • Interdisciplinary Efforts Lead to Imaging Tag for MRI

    In a collaborative and highly interdisciplinary effort, the Wang, Warren, Malcolmson, Blum, and Theis labs have disclosed a new class of molecules that may be used as biomolecular tags for MRI, potentially enabling metabolic processes to be viewed in real time.  The work, published in the journal Science Advances and highlighted in Duke Today, details the hyperpolarization of these molecules through an iridium-catalyzed spin-polarization transfer from singlet-state hydrogen gas, increasing NMR signals,
