"CAE for Lightweight Vehicle Development"

The automotive industry shares the goal to develop advanced vehicle structures which are light weight yet perform well for a variety of performance criteria without incurring significant penalties to manufacturing costs or efficiency.  In order to further improve the efficiency of our development process and the quality of our products Honda has increased our ability to predict performance for a given vehicle design using Computer Aided Engineering.  This presentation will highlight current CAE methods used for virtual validation of vehicle designs and consider computational challenges for future greater application of  lightweight materials and technologies.

“Computational angle to vibrational spectroscopy of heterogeneous chemical interfaces”

Heterogeneous chemical interfaces play increasingly important role in the nano-technology. We are in a great need for better methods that could study surfaces and atomic-scale interfaces, able to reveal physical and chemical properties that vary on the scale of a few chemical bonds. Raman spectroscopy promises exciting opportunities, being able to report not only about a particular chemical species, but also about its interaction with the immediate chemical environment. It utilizes interactions of light with atomic vibrations, and provides unique “fingerprints” of any chemical species. While the conventional Raman spectroscopy cannot be used at the nano-scale due to its extremely small scattering cross section and the far-field diffraction limit of light, the Surface Enhanced Raman Spectroscopy (SERS) has emerged to overcome these weaknesses.

In this talk, I will give a brief overview of SERS and focus on the chemical aspect of this phenomenon, to demonstrate how Raman interactions can reveal local chemical interactions, visualizing the role of the interfacial electron-phonon coupling. Our computationally - intensive results obtained using Oakley demonstrate unique capabilities of the Raman scattering for studying interfacial properties, especially focusing on the aspect of the interfacial charge transfer. As a particular example, I will present Raman analysis of molecule-surface interactions tuned by external electric bias.
