    Rutgers University physics major Jennifer Coulter struck academic gold three times this year, winning a National Science Foundation Graduate Research Fellowship, a National Defense Science and Engineering Graduate Fellowship and a Department of Energy Computational Science Graduate Fellowship.Coulter, a graduating senior, was honored with a prestigious Goldwater scholarship last year. At MIT, Coulter was a research assistant to Alfredo Alexander-Katz, an associate professor in the Department of Materials Science and Engineering. She modeled how spinning colloidal particles move through a fixed array of obstacles.

    Liquid tin-sulfur compound shows thermoelectric potential

    MIT researchers base high-temperature device to produce electricity from industrial waste heat on molten compound's semiconducting properties.

    Thermoelectric test cell

    MIT researchers have developed a liquid thermoelectric device with a molten compound of tin and sulfur that can efficiently convert waste heat to electricity, opening the way to affordably transforming waste heat to power at high temperatures.

    Youyang Zhao, a graduate student in Assistant Professor of Metallurgy Antoine Allanore's research group, built a thermoelectric test cell that operates in a liquid state at temperatures from 950 to 1,074 degrees Celsius [1,742 to 1,965 degrees Fahrenheit].

    Predicting high-temperature, liquid electronic properties

    Graduate student Cooper Rinzler and Assistant Professor of Metallurgy Antoine Allanore develop new formulas for analyzing molten semiconducting compounds.

    Graduate students Cooper Rinzler and Youyang Zhao and Assistant Professor of Metallurgy Antoine Allanore developed new formulas for predicting which molten compounds will be semiconducting and built a high-temperature thermoelectric test device.
    Rinzler, Zhao and Allanore.

    Despite decades of research on solid-state semiconductors, much remains to be discovered about these materials when they are heated to their liquid state. Assistant Professor of Metallurgy Antoine Allanore and his lab group are discovering new tools to understand these molten electronic materials.

    Doctoral candidate Charles Cooper Rinzler and Allanore co-authored two papers that lay out a framework for quantifying the entropy [thermodynamics], chemical structure [configuration of atoms] and electronic behavior in liquid semiconducting compounds.

    Metals and minerals form the base of our society, with diverse applications infiltrating all corners of our lives, including agriculture, infrastructure, transportation and information technology. As populations grow, and demand for metals and minerals rises, enhancing the sustainability of the sector is a goal for many companies, communities and policymakers.

    To contribute to this, on May 11-12, 2017, MIT launched the Metals & Minerals for the Environment (MME) initiative with its first public Symposium. MIT has long been home to research on myriad aspects of metals and minerals, and the MME Symposium serves to crystallize these efforts around the unique environmental and social challenges the sector faces.

    The 3-D printer that could finally change manufacturing

    The propeller after processing provides an example of a high-performance part that can be made with 3-D printing. Engineers can use the method to prototype and optimize different designs.

    Desktop Metal thinks its machines will give designers and manufacturers a practical and affordable way to print metal parts.

    Desktop Metal, has raised nearly $100 million from leading venture capital firms and the venture units of such companies as General Electric, BMW, and Alphabet. The founders include four prominent MIT professors, including the head of the school's department of materials science and Emanuel Sachs, who filed one of the original patents on 3-D printing in 1989. Still, despite all the money and expertise, there's no guarantee the company will succeed in its goal of reinventing how we make metal parts - and thus transform much of manufacturing.

    About MPC

    The goals of the Materials Processing Center are to unite the materials research community at MIT and to enhance Institute-industry interactions. Collaboration on research ventures, technology transfer, continuing education of industry personnel, and communication among industrial and governmental entities are our priorities. The MPC Industry Collegium is a major vehicle for this collaboration. The MPC sponsors seminars and workshops, as well as a summer internship for talented undergraduates from universities across the U.S. We encourage interdisciplinary research collaborations and provide funds management assistance to faculty.
