        At the Materials Simulation for Clean Energy (MSCE) Lab, Yue Qi and her group develop multi-scale simulation methods to design materials atom by atom. They screen materials chemistry by solving quantum mechanical equations to predict the properties that are difficult to measure experimentally. They also work to simulate deformation and reaction processes that involve millions of atoms using molecular dynamics with faster and accurate atomic interactions. By utilizing the High Performance Computing Center (HPCC) at MSU, they are predicting chemical-mechanical degradation mechanisms in Li-ion batteries without fitting parameters. They model how electron and ion transport in complex materials and interphases in order to design new materials and optimize operating conditions for advanced Li-ion batteries and solid oxide fuel cells. Qi and her group simulate how mechanical properties of lightweight metals change in gas and liquid environment starting from their atomic interactions in order to design new tool coatings and manufacture processes. All of these materials are critically important for an energy efficient and sustainable transportation industry.

          Two of the most prominent ways to model the time evolution of complex many-body systems are hydrodynamics and kinetic theory. Over the last two decades, MSU University Distinguished Professor Wolfgang Bauer has made several contributions to the kinetic theory based description of subatomic reactions and has advanced our understanding of experiment observables in high and medium energy heavy ion reactions. In particular, his work has led to a deeper understanding of the nuclear equation of state and phase transitions of nuclear matter in finite size systems. Now Prof. Bauer is applying his techniques and computer models to systems of vastly different length, mass, and time scales: the supernova explosions of massive stars at the end of their live. Modeling supernova explosions has long been the domain of hydrodynamics. However, these explosions are, to a large degree, driven by neutrinos. These neutrinos can have very long mean free paths due to their very small interaction probabilities and are thus not in the domain of validity of hydrodynamics. The conventional way to remedy this shortcoming is to couple hydrodynamics to a neutrino Boltzmann transport calculation. Bauer's answer is much more straightforward: apply kinetic theory, which is free of assumptions about the mean free paths, to all matter constituents, baryons as well as neutrinos. In his approach, he and his research group simultaneously solve billions of coupled first-order differential equations in time for so-called testparticles, which makes their work an ideal candidate for massively parallel multi-processor environments such as those provided by iCER's High Performance Computer Center.

            Professor Thomas Pence and Dr. Kun Gou in the Department of Mechanical Engineering at Michigan State University are working on a research project entitled "New mathematical models for the large strain swelling response of biological tissues." This is an international project sponsored by the Qatar National Research Foundation in collaboration with Carnegie Mellon University in Qatar. Professor Pence is the Principal Investigator in charge of the overall project. Understanding how the human trachea (windpipe) can swell due to an allergic reaction is part of this research. Angioedema, the technical term for such tissue swelling, refers to the rapid excess accumulation of fluid in under-skin tissue from blood vessel leakage. When this occurs in the trachea, it can rapidly narrow the airway leading to a life threatening condition. Bringing an engineering perspective to describe this process offers the possibility of developing new methods of treatment. To analytically describe the swelling process, it is necessary to improve traditional mechanical theories of tissue behavior so as to account for an episode of rapid swelling. To do so, they present a continuum mechanics analysis in which conventional large strain hyperelastic theory is endowed with a swelling dependent natural configuration in order to reflect the altered tissue volume when angioedema is triggered by an allergic attack. The trachea can be visualized as a two layered tube. The inner layer, which is thin, is the soft mucous tissue that lines the airway. The relatively thicker outer layer is mostly cartilage and this provides the main structural support for the windpipe. The swelling is largely confined to the inner layer and this idealization is part of the model analysis. The inner layer also has directional anisotropy associated with a longitudinally aligned fibrous microstructure. The interaction among swelling, anisotropy and large deformation determines the overall airway constriction. The computation of the modeling is based on an finite element formulation. This effectively breaks up the trachea into a collection of small structures-- the finite element mesh. Due to the thin but very long geometry of trachea, extremely fine tetrahedral meshes are needed to obtain an accurate result. Standard computers bog down or even crash when faced with such a computational task. "Thanks to the powerful computational resources in HPCC at MSU, we can parallelize our code and run it in various nodes and cores simultaneously," Gou and Pence commented, "The storage of large amounts of data can also be resolved. This vastly shortens the running time and provides us more flexibility to analyze the result."

              Electrical Engineering Professor Adam Mock from the School of Engineering and Technology at Central Michigan University performs computational electromagnetic modeling of micrometer and nanometer scale photonic devices. While these devices are microscopic in size, the similarly microscopic optical wavelength must be sufficiently resolved in simulations. For devices with sub-wavelength features in all three dimensions, computational demands are significant. Fortunately the state of the art HPCC resources at MSU make multi-parameter optimizations tractable. Professor Mock’s photonic device research targets three primary applications: (1) chip-scale optical data communication, (2) optical sensing, and (3) solar energy. In each application, device goals revolve around controlling or measuring the direction, speed and/or intensity of light. (1) Chip-scale optical data communication: The world’s communication infrastructure is made up of thousands of kilometers of glass optical fibers that connect people on opposite sides of the earth. While this technology is excellent at transporting data over long distances, routing and switching the data to ensure that it reaches its intended recipient often requires signal processing in the electrical domain. Current research seeks to perform switching, routing and other signal processing in the optical domain to improve speed, cost and power consumption. The goal of this work is to produce photonic integrated circuits in which hundreds of data channels can be processed simultaneously. These technologies are beginning to be deployed in highly connected data centers. Professor Mock is primarily interested in small footprint microresonators for light generation, filtering and switching. (2) Optical sensing: Optical sensors use light to measure the quantity of a particular gas or liquid. This is done by measuring how much light is absorbed by a sample or by a change in the sample’s refractive index. Careful design of sub-wavelength geometries and use of specialized materials can enhance the sensitivity, the response time or both. Continued engineering of sensor technologies will make them even more ubiquitous in industrial, military and controlled environment settings. Professor Mock’s work is investigating microstructured optical fibers as highly sensitive optical sensors with fast response time that can be easily deployed for continuous monitoring in large areas. (3) Solar energy: As humans’ energy needs continue to grow, the conversion of light energy from the sun into electrical energy is going to play an increasing role in our energy portfolio. Photovoltaic technologies involve two important engineerable processes: trapping light and converting the trapped light into electrical current. Both processes continue to be studied and optimized, and highly accurate device modeling plays a crucial role. Professor Mock is investigating improved light trapping and absorption via highly scattering nanocomposites.
