    Modeling how colloidal particles spin though a fixed array

    Jennifer Coulter worked on modeling the behavior of ferromagnetic particles stimulated by a rotating magnetic field to spin in a passive cluster of non-magnetic particles.
    Summer Scholars

    MPC-CMSE Summer Scholar Jennifer Coulter interned with MIT Associate Professor Alfredo Alexander-Katz's group this summer on a generalized computer model for active spinning particles moving in a passive colloidal mixture. 
    "We're studying the interactions of the spinners with the passive particles through simulation," Coulter says. 
    Earlier this year, Alexander-Katz  demonstrated experimentally that ferromagnetic particles spinning under a rotating magnetic field in a milky suspension are attracted to each other across relatively long distances in a crowd of non-magnetic particles.

    Cancer has long been known to make its immediate environment more acidic and starve it of oxygen [hypoxia], making measurements of these changes clinically important. "The amount of radiation you want to use to kill that tumor depends on how hypoxic the tumor is, and typically we don't know how hypoxic it is," says Michael J. Cima, David H. Koch Professor of Engineering at MIT.
     
    MPC-CMSE Summer Scholar Michael Concepción Santana worked in the Cima Lab in the Koch Institute for Integrative Cancer Research at MIT, on a project to develop hydrogels that can serve as internal sensors, readable with an MRI, of a patient's pH levels at a tumor site. Hydrogels are polymers that absorb large amounts of water.

    A convection oven cooks more uniformly because a fan creates a steady flow of hot air around the food being cooked. MIT's St. Laurent Career Development Professor of Chemical Engineering, Fikile R. Brushett, is applying that principle to a new water-based battery design that pumps a steady flow of charge-carrying ions through a battery to create a more uniform distribution of ions in the cell.

    "We're fabricating an aqueous [water-based] battery which is safe, cheap and scalable," MPC-CMSE Summer Scholar Victoria Yao explains. A rising junior at Vanderbilt University, Yao is majoring in chemical engineering. This summer, she worked with graduate student Thomas J. Carney to develop a convection cell battery, in which electrolyte would flow through the electrode material, rather than remain static as in a conventional battery.
    Tiny gold grids yielding secrets  

    Summer Scholar Justin Cheng holds an experimental sample of nanostructured gold on silicon that has potential for use in sensors, catalysts and display technologies based on selective light absorption.

    Ordered patterns of gold nanoparticles on a silicon base can be stimulated to produce collective electron waves known as plasmons that absorb only certain narrow bands of light making them promising for a wide array of sensors and display technologies in medicine, industry and science.
     
    MPC-CMSE Summer Scholar Justin Cheng worked this summer in Professor of Electrical Engineering Karl K. Berggren's Quantum Nanostructures and Nanofabrication Group to develop specialized techniques for forming these patterns in gold on silicon. 
     
    "Ideally, we'd want to be able to get arrays of gold nanoparticles to be completely ordered," Cheng says.
        
    In Other News

    MIT researchers integrate a scaffold of carbon nanotubes within a polymer glue. They first grew a forest of vertically-aligned carbon nanotubes and transferred it onto a sticky, uncured composite layer. Then they repeated the process for 16 plies.

    Simulations written in Simit, a new programming language, were dozens or even hundreds of times as fast as those written in existing simulation languages.

    Researchers from MIT and MIT Lincoln Laboratory report an important step toward practical quantum computers, with a paper describing a prototype chip that can trap ions in an electric field and, with built-in optics, direct laser light toward each of them.

    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.
