2015 Materials Research Society (MRS) Fall Meeting Hynes Convention Center, Boston MA
Abstract
Symposium V: Gradient and Laminate Materials: The US Army is interested in new structural materials that are strong, ductile and light-weight for mission-related applications ranging from body armor to protecting the extremities of soldiers to transportation vehicles. Gradient materials have a superior combination of strength and ductility that is not accessible by conventional homogeneous materials, including nanocrystalline and coarse-grained materials. Such superior mechanical properties make them attractive for the aforementioned army-related applications, such as body armor and transportation materials. In addition, the gradient structured materials are also more corrosion resistant, and have longer fatigue life, which will significantly increase the service life of the army vehicles and other structures. Therefore, it is of the interest to the Army to promote the research and development of gradient materials at large scales and low costs. Gradient and laminate materials are an emerging area with the potential to become a major research field for the communities of materials, mechanics and physics in the next few years. They also have potential in many applications such as strong and tough structures, energy efficient automobiles, etc. There are many fundamental issues that need to be studied by experiments, analytical modeling, and computer modeling. This symposium, and the symposia that will follow in the future, will act as a forum to bring multidisciplinary researchers together to exchange ideas, discuss key issues, and promote industrial technology development for commercial production and applications. Symposium WW: Modeling and Theory Driven Design of Soft Materials: The symposium encompassed seven half-day oral sessions and one poster session and provided a platform for nurturing scientific exchanges on the latest developments on the design of soft materials resulting from the integration of computational and theoretical approaches. Functional integration of synthetic and naturally occurring molecular building blocks has produced a generation of hybrid soft materials with responsive and highly tunable physical properties. Soft materials are increasingly finding application in areas that include flexible electronics, energy storage and battery technology, anti-reflective coatings and surfaces with tailored refractive indices, additives that reduce engine wear and increase fuel efficiency, more efficient heating and cooling technologies, better display technologies, environmental remediation, targeted drug delivery, and improved contrast in magnetic resonance imaging. Symposium BBB: Liquids and Glassy Soft Materials - Theoretical and Neutron Scattering Studies: The phase behaviors of liquids and glasses are exceptionally rich, and in-depth understanding of them requires the development of new theoretical concepts and new experimental techniques. This symposium focused on the forefront of the liquids and glassy soft materials research and discussed the best practices of the cutting-edge neutron scattering experimental tools, as well as the related theories and multi-scale modeling and simulations. The symposium was also a great attempt bringing together researchers from the traditional metallurgy field, molecular field, and soft matter field. Such cross-linking of concepts and languages is useful to bridge the gaps. Many universal phenomena across systems of different length scales are identified, and there is a need of similar efforts from the community in the future. ARO funding was allocated for registration and travel support for invited speakers, early-career researchers, and graduate and post-doctoral students participating in the three symposia.
