Symposium presentations

Of the symposia at the Meeting, more than 15 were directly related to sustainability. Materials science plays an important role in the sustainable supply of energy, water, products, services, transportation, buildings, and public infrastructure. The Energy and Environment Symposium encouraged an approach toward the role of materials science in sustainable development and provided a medium for technically based, interdisciplinary discussions. Topics included materials for alternative energy sources, materials designed for enhanced recyclability, and objective application of economic, sociological, and governmental models that enable materials research and technological developments.

In a Soft Materials and Biomaterials Symposium talk, Koon Gee Neoh, from the National University of Singapore, discussed the devastating problem of bacterial biofilm formation on implanted medical devices, such as catheters. These bacteria can also harbor on hospital surfaces. Neoh has developed strategies to coat surfaces with antimicrobial materials using UV or heat-induced graft polymerization, thiol-linking, and cross-linking. She uses quaternized chitosan as a bactericidal material to kill adherent bacteria on hospital surfaces. The desired result is a reduction in the patients’ risk of infection during hospital stays.

Andrew Minor discussed dramatic improvements in in situ transmission electron microscopy (TEM) mechanical testing in a Characterization and Modeling of Materials Symposium presentation. The true value of TEM lies in studying structure and defects with high spatial resolution. Minor and his collaborators at the National Center for Electron Microscopy have developed a technique to locally capture strain during in situ mechanical testing. The basis of their work is the direct, rapid collection of 2D electron diffraction patterns from a nano-focused beam (nanobeam electron diffraction) at each point in a raster-scanned image. This is different from typical TEM experiments, as instead of choosing a bright- or dark-field imaging mode, all information is collected simultaneously and can be filtered during post-processing. No longer is it necessary to maintain perfect zone axis alignment, allowing strain maps to be captured over sample areas and completely through a defect with 1 nm resolution.

In an EP4 Symposium presentation, Daniel Chung, University of New South Wales, discussed how solar cells made of multi-crystalline silicon (mc-Si) have recently proven to have more to offer in terms of efficiency consecutively lowering the cost of solar power. As the cell design improves, the quality of the mc-Si becomes more critical, putting pressure on impurity control in the making of silicon for solar cells. Chung described how a solar-cell in-line tool based on photoluminescence imaging is capable of fast and reliable quantification of a wide range of electronic material and device parameters.

Plenary Session featuring the Fred Kavli Distinguished Lectureship in Materials Science and Symposium X presentations

At Tuesday’s plenary session, Cato T. Laurencin of the University of Connecticut discussed his work on regenerative engineering in the context of materials science and engineering. Laurencin studies musculoskeletal injuries from the viewpoint of scientific and clinical research.

Laurencin was inspired to enter this area of research in the 1980s after a talk by Y.C. Fung, who coined the term “tissue engineering” at a National Science Foundation workshop. Laurencin said the future of tissue engineering lies in regenerative engineering using biomaterials. This “convergence” of advanced materials science, stem cell science, physics, developmental biology, and clinical translation lead to the regeneration of complex tissues, organs, or organ systems. From a materials science perspective, most research in this “convergence” area focuses on nanoscale interactions. In particular, nanoscale surface architecture can strongly influence cellular events at the cell/materials interface because cells are highly sensitive to their physical surroundings.

For the Symposium X: Frontiers of Materials Research presentations that started on Tuesday, Annette Richards, Cornell University, and Catherine Oertel, Oberlin College, explored the nature of how musical sounds are made and materials’ roles in the quality of the sounds produced in an organ. To restore and maintain antique instruments, there needs to be an understanding of the properties of historic organ-pipe metal, for example.

Oertel cited several causes for organ-pipe corrosion, but organic acids, acetic acid in particular, emitted from the wood of organ cases were significant corrosive agents for lead-rich pipes. The collaboration made field observations of conditions in historic organ cases a basis for designing laboratory experiments to study the role of alloy composition and humidity in the susceptibility of pipes to organic acid attack. In short-term (one-month) experiments, they found that at 95% relative humidity, acetic-acid attack on lead–tin alloys increased with increasing tin content, in contrast to observations at lower humidities. This information has led to strategies, such as using different woods and providing ventilation and sensors, to keep acid release and humidity under control.

On Thursday, Gerbrand Ceder, University of California, Berkeley, discussed the Materials Project (MP), a US Department of Energy-funded, multi-institutional collaboration launched in late 2011 and headquartered at the Lawrence Berkeley National Laboratory. It aims to provide the capability to query properties for novel compounds upon request, information to be used in selecting materials for whatever application the requestor has in mind. Acknowledging that the most basic properties (analogous to genes) are not necessarily the ones useful for materials selection, Ceder said that the MP approach is to invest in basic property calculations that can be used toward obtaining multiple higher-order properties. For example, elastic tensors lead to a variety of properties, including elasticity, thermal transport, dislocations, and free energy. There are more than 66,000 compounds in the system, about which there is some information and almost 17,000 users. Ceder concluded that the ab initio prediction of materials properties is accelerating, and one may expect a fairly complete compound genome within the decade.

On Friday, John Spence of Arizona State University provided a detailed examination of the issues involved in achieving today’s frontier of “movies” of materials and biological systems with atomic spatial resolution and femtosecond temporal resolution. Spence has a long career in electron microscopy to which he has more recently added x-ray imaging at synchrotron radiation sources and x-ray lasers. He started by discussing electron imaging with fast detectors, and then turned to x-rays. Spence closed with a description of a new project that has begun at Arizona State University to build a compact x-ray light source that fits in one room and will cost USD$6 million. The basic idea is to use a laser beam directed antiparallel to an electron beam. The effect is that of an undulator with a period equal to the laser wavelength, 1 µm rather than the 1 cm typical in magnetic undulators. To get the same x-ray wavelength, the electron beam can be correspondingly smaller (25 MeV rather than 1 GeV), thus shrinking the size and cost of the device dramatically.

Highlights

Former US Secretary of Energy and Nobel laureate Steven Chu of Stanford University opened this Meeting’s Technology Innovation Forum. Chu is the William R. Kenan, Jr., Professor of Physics and Professor of Molecular and Cellular Physiology in the medical school at Stanford University. He was the 12th US Secretary of Energy from January 2009 until the end of April 2013.

As the Secretary of Energy, Chu launched the Advanced Research Projects Agency-Energy (ARPA-E) and the Energy Innovation Hubs. He set up the funding and research systems of these programs by relying on what he had learned at AT&T Bell Laboratories. At ARPA-E, the managers are active scientists. They make their funding decisions in days rather than in years, and they have a work culture of animated discussions. ARPA-E was established to fund high-risk, high-impact energy projects.

Similarly, the Energy Innovation Hubs are designed to eliminate hierarchical control in order to empower managers to hire the best researchers and give them freedom to work. These Hubs plan for what Chu called a “10-year horizon” from research to prototype. The mission of national laboratories, Chu said, is to do very good research for the public good. The method to accomplish this, he said, is to “get the best people, empower them, and let them go charge.”

At the second edition of MRS’ Innovation in Materials Science, or iMatSci, Stephen Forrest of the University of Michigan gave the keynote address. Having co-founded or been a founding participant in numerous companies, Forrest was well positioned to assess what he called the “innovation economic ecosystem” that elicits successful startup companies.

Forrest said, “Your technology is not nearly as important as your market.” He emphasized the importance of using every available resource, including the need for academics to partner with industry, and for industry to collaborate with many partners in order to remain competitive. The keynote address was followed by a panel discussion on venture funding.

Dianne Chong addressed the Women in Materials Science & Engineering Breakfast on Wednesday morning, discussing the role innovation plays in stability and change. Chong, who served as the vice president of Boeing Research and Technology said that the definition of “innovation” is often misunderstood. For companies to remain competitive, they need to adapt to changes. They also need an element of stability in order to stay in business.

Within the current competitive climate, companies must make new products and move them into market within a short time frame. One way to do this is to license out products to manufacturers and the market that is ready to use them, Chong said. Furthermore, critical to getting a product “ready” for market is to form partnerships with other companies. For example, various parts of a particular Boeing airplane can be made up of numerous composites that have been developed by as many as a dozen different companies. This is what Chong refers to as innovation in a business model.
