  • Folding Wrinkles of a Thin Stiff Layer on a Soft Substrate

    Folding Wrinkles of a Thin Stiff Layer on a Soft Substrate

    Jeong-Yun Sun, Shuman Xia, Myoung-Woon Moon, Kyu Hwan Oh and Kyung-Suk Kim

    We present the mechanics of folding surface-layer wrinkles on a soft substrate, i.e. inter-touching of neighbouring wrinkle surfaces without forming a cusp. Upon laterally compressing a stiff layer attached on a finite-elastic substrate...  View publication

  • FePt Nanoparticles Assembled on Graphene as Enhanced Catalyst for Oxygen Reduction Reaction

    FePt Nanoparticles Assembled on Graphene as Enhanced Catalyst for Oxygen Reduction Reaction


    Shaojun Guo and Shouheng Sun

    Seven-nanometer FePt nanoparticles (NPs) were synthesized and assembled on graphene (G) by a solution-phase self-assembly method. These G/FePt NPs were a more active and durable catalyst for oxygen reduction reaction (ORR) in 0.1 M HClO4 than the same...View publication

  • Real-time Droplet DNA Amplification with a New Tablet Platform

    Real-time Droplet DNA Amplification with a New Tablet Platform

    Stephanie L. Angione, Anuj Chauhan, and Anubhav Tripathi

    We present a novel droplet-based tablet platform for temporal polymerase chain reaction (PCR) in microliter droplets. The simple design of the device does not require extensive processing or external equipment, which allows for greater ease of use and integration as a point-of-care diagnostic...View Publication

  • Heat Flow in Nanostructures in the Casimir Regime

    Heat Flow in Nanostructures in the Casimir Regime

    Humphrey J. Maris and Shin-ichiro Tamura

    In small structures the phonon mean free path due to phonon-phonon interactions and defect scattering may exceed the sample dimensions.  The thermal conductivity then becomes dependent on the size and shape of the sample... View Publication

The Institute for Molecular and Nanoscale Innovation (IMNI) at Brown University was founded in 2007, and IMNI serves as an umbrella organization to support centers and collaborative research in materials, molecular and nanoscale sciences and technologies.  IMNI is a "polydisciplinary" venture with over 80 participating faculty members representing nine departments across campus, and 12 staff members.  

Much of IMNI research activity is centered around three broad themes:

  • Center for Advanced Materials Research
  • Center for Nanoscience & Soft Matter
  • Nanohealth Initiative 

IMNI serves as a focal point for interaction with industry, government, and our affiliated hospitals.  IMNI supports and administers: seed funding, scientific team building, proposals preparation, post-award block grants, seminars, special events, and nanoscience course offerings across campus.

IMNI manages three major core research facilities:  Microelectronics Facility, Electron Microscopy Facility, NanoTools Facility - and the Joint Engineering/Physics Instrument Shop.
