    Machine Learning Applied to Materials Science
    Rajendra Joshi and an image representing his research A research article by Rajendra Joshi, a Science of Advanced Materials Ph.D. student from Nepal, was recently published in the journal, ACS Applied Materials and Interfaces.

    His research, supported by grants from the Department of Energy, proposes a method, based on machine learning, that “allows us to do a very quick evaluation of the voltage that a material will provide in a battery,” said CMU physics faculty member Juan Peralta. “Previously, testing materials was time consuming and expensive.”

    If a new material is found to provide useful a voltage, scientists and engineers can use that material to create new battery technologies, thus Rajendra Joshi’s work allows for quicker and cheaper development of real world devices such as laptop computers and cellular phones.

  • Du's research on glucose poly(ortho esters) featured on cover of Angewandte Chemie
    February 13, 2014 - Assistant professor of chemistry and Science of Advanced Materials research scientist Wenjun Du recently had his research featured as the cover story on the journal, Angewandte Chemie.

    His paper - "Synthesis of Highly pH-Responsive Glucose Poly(orthoester)" - hypothesizes that pH-responsive polymers have great potential in biomedical applications, including targeted drug delivery.

    Since tumors and inflammatory tissues tend to have low pH values and existing pH-responsive materials, such as polyketal copolymers, had known limitations and were falling short in terms of treating conditions optimally, Du and his research colleagues synthesized a glucose poly(orthoester) as a highly pH-responsive polymer to address these issues. Their research demonstrates the first, successful creation of a new class of sugar-based polymers, in which the sugar units are connected through orthoester linkages.

    Ths new discovery has broad applications and may be useful in the synthesis of highly pH-responsive materials that could selectively and rapidly deliver drugs to diseased tissues with low pH values.

    Du and his team plan to continue their study of glucose poly (ortho esters), with additional research studies already underway in his laboratory.

    Angewandte Chemie is one of the premier chemistry journals in the world. It is the only journal in the field that delivers a mix of review articles, highlights and communications weekly, and also regularly publishes Nobel lectures in chemistry and related fields.

  • CMU physics professor invited to provide expert commentary on materials research in Physics' Viewpoint paper
    February 13, 2014, 2013 - Physics professor and Science of Advanced Materials research scientist Marco Fornari was recently published in Physics, the online publication of the American Physical Society that spotlights exceptional research. Fornari was invited to write a Viewpoint commentary on the research article, "Comprehensive Search for New Phases and Compounds in Binary Alloy Systems Based on Platinum-Group Metals, Using a Computational First-Principles Approach," explaining the results of recent research conducted at Brigham Young University to physicists in other subfields.

    In his invited paper, Fornari notes that being able to use powerful computers to search for new and improved functional materials - particularly new platinum-group-metal-containing alloys that have proven useful for a wide range of industrial applications - yields significant time-saving by allowing researchers to explore potentially useful chemical combinations of elements and structures in a fraction of the time that real experiments would take. Results are organized in a database that researchers then go through to analyze the relationships between multiple materials. Through their analysis, they create what are called "property descriptors" - quantities that link the calculated microscopic and macroscopic properties - and what research scientists use as a compass to navigate these complex, multidimensional materials databases. They hope that this "high-throughput materials modeling" will expedite the discovery and development of new materials, and their applications to real-world issues.

    The researchers at Brigham Young University used a supercomputer and software called AFLOW to process 153 binary combinations of platinum group and transition metals, calculating the energies of 250 different possible crystal structures. They were able to identify crystal structures that had already been found, but also discovered 28 new, unexplored alloys that could have potential use.

    Fornari indicates in his review that although years might be needed to examine all of the leads yielded by this particular study, it highlights the need for greater standardization in how materials are catalogued in various databases. This would help achieve a long-term goal of high-throughput materials modeling of allowing searches to automatically generate new descriptors for new functionalities, and in turn, enhancing material scientists' research abilities through data mining to expedite the discovery of new materials and their potential uses.

  • Two CMU physics professors awarded research grants from National Science Foundation and U.S. Department of Energy
    February 11, 2014 - Two CMU Science of Advanced Materials faculty members were recently recognized for their research:

    Assistant professor of physics Veronica Barone was awarded a Chemical, Bioengineering, Environmental, and Transport Systems (CBET) grant from the National Science Foundation to work on sodium-ion batteries research in collaboration with professor Liangbing Hu at the University of Maryland. Due to the low cost and abundance of sodium on Earth, sodium-ion batteries are emerging as a viable technology to meet the requirements for transportation and other energy storage applications. Although sodium is much more abundant than lithium, sodium ions have a much larger size, which poses grand challenges for sodium-ion technologies. Barone's research group at CMU will address these issues by utilizing computational tools to investigate possible sodium-ion storage mechanisms, such as intercalation and cluster formation.

    Professor of physics Koblar Alan Jackson has received a three-year grant from the U.S. Department of Energy's Office of Basic Energy Science to study the physics and chemistry of cluster-based catalyst systems using computer simulations. The grant will support Science of Advanced Materials and CMU Department of Physics graduate students who have research interests in computational studies of atomic clusters and nanomaterials.

  • Howell receives international award for work in thermal analysis
    April 22, 2013 - Central Michigan University professor of chemistry and polymer science Bob Howell has received the 2012 North American Thermal Analysis Society Award for Outstanding Achievement in thermal analysis research.

    "Thermal analysis has to do with just the response of materials to a change in temperature," Howell said. "You can learn about the structure of the material based on the way it responds, and so that's the fundamental technique."

    Howell applies his research in a number of ways, focusing primarily on studying polymer degradation at different temperature ranges. For example, his research to address the issue of foul taste and brown streaking in milk jugs - and his proposed solution - helped reduce the cost of milk production and was considered particularly noteworthy by the society.

    The solution to issues with milk containers linked back to Howell's research with The Dow Chemical Co., where in the mid-1980s he was asked by Dow to experiment with using polymeric materials in food packaging, and successfully adapted the materials to stop the streaking.

    Most containers are made with different layers of various polymer materials, each with a different composition. The elimination of the streaking allows the milk to be stored at room temperature. "Because no oxygen gets in, the milk doesn't spoil," Howell said.

    Howell has also worked to remove odors from degrading polystyrene, the plastic material used in packaging food, such as cookies and pastries.

    The Outstanding Achievement award from NATAS is unique to a university of CMU's size. Given annually, it recognizes distinguished achievement in the field of thermal analysis, including but not restricted to thermogravimetry, differential thermal methods and effluent gas analysis. The award recipient must have performed outstanding work in the utilization, creation or refinement of thermal techniques of generally wide interest and impact.

    Howell is the 44th recipient of this award, which represents the highest honor bestowed by the Society.
