    Silicon Telluride: Brown Chemists Make New Silicon-Based Nanomaterials

    A new process developed by researchers at Brown University uses silicon telluride to produce multilayered two-dimensional semiconductor materials in a variety of shapes and orientations. View Publication

    Nanowires highly ‘anelastic,’ research shows

    A slow return

    Zinc oxide nanowires return to shape slowly after being bent. That property, called anelasticity, suggests that nanowires might be good in applications that require absorption of shocks or vibrations. Full Article

    Researchers Predict Material with Record-Setting Melting Point

    Compounds made from hafnium and carbon have some of the highest known melting points. Using computer simulations, Brown University engineers predict that a material made with hafnium, nitrogen, and carbon will have a higher melting point than any known material.View Publication

    Researchers Simulate Behavior of 'Active Matter'

    Microspheres in a fluid, spinning in opposite directions, create flow patterns that affect other particles. Computer simulations show the particles self-assembling into different structures at different concentrations: bands, small swirls, a single large vortex.

    DNA ‘cage’ could improve nanopore technology

    A Nanoscale Cage

    An electrical field draws a strand of DNA in by the smaller hole, bottom, but the curled DNA cannot exit through the larger hole, top. After experimental procedures, a reversed electrical field draws the DNA strand back out of the lower hole, allowing before and after comparison.

  • A Better Method For Making Perovskite Solar Cells

    A Better Method For Making Perovskite Solar Cells

    Faster, cooler, thinner, better Perovskite solar cells could be a cheap, efficient alternative to silicon-based solar cells. A new technique can potentially mass-produce thinner perovskite films at room temperature without sacrificing quality. Thin-film perovskite solar cells could be used for colorful windows that can generate electricity. Padture lab/Brown University

    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

  • 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

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.
