    Researchers discover new lead-free perovskite material for solar cells

    Researchers have shown that titanium is an attractive choice to replace the toxic lead in the prevailing perovskite thin film solar cells. Full Publication

  • Earth-Abundant Nontoxic Titanium(IV)-based Vacancy-Ordered Double Perovskite Halides

    Earth-Abundant Nontoxic Titanium(IV)-based Vacancy-Ordered Double Perovskite Halides

    The possibility of lead (Pb) contamination and the volatility of the organic cations in the prevailing Pb-based organic-inorganic perovskite (HP) light absorbers are the two key issues of concern in the emerging perovskite solar cells (PSCs). Full Publication

    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.

    Nanowires highly ‘anelastic,’ research shows

     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.

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:

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.
