  • 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) was founded in 2007 and serves as an umbrella organization to support centers and collaborative research teams in materials science, and in the molecular and nanosciences.  IMNI is a "polydisciplinary" venture with more than 60 faculty members, representing nine departments across campus.  IMNI also serves as a focal point for interaction with industry, government, and our affiliated hospitals.  IMNI supports scientific team building, proposal preparation, block grant management, seminars, special functions, and nanoscience course offerings across campus

Much of our activity is centered around three major research themes:

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

IMNI also runs four major core research facilities:  The Microelectronics Facility for lithography and fabrication, The Electron Microscope Facility with SEM, TEM, FIB and optical microscopy, the Joint Engineering/Physics Instrument Facility, and the IMNI Nanotools Facility for spectroscopy and scanning probe techniques.
