The project: Prognostic Health Management of DoD Assets
The issue: Acoustic emission-based structural health monitoring techniques have great potential for determining the current state of health of critical structures, such as Army vehicles and weapons systems, and predicting their future performance. However, current technology relies mostly on empirical approaches for interpreting AE signals, a technique that has been plagued by ambiguity and false positives.
With a better understanding of the physics of acoustic emission (AE) signal propagation and the development of signal processing techniques, AE-based techniques can play a larger role in developing highly efficient, adaptive, and survivable vehicles, armor, and machinery and the assurance of their safety and integrity.
Abstract: This research will develop numerical models, experiments, algorithms, web architectures, and other tools applicable to prognostic health management. The research will address identification of critical damage states in composite structural elements and strategies for sensing such states with multiple sensors.

The project: Cell-based toxicity assay-on-chip for the next-generation CMOS technology
The issue: It is recognized that the unique quantum properties of engineered nanomaterials (ENs) strongly influence their physico-chemical properties, resulting in novel electrical, optical, thermal and magnetic properties not present in their corresponding bulk counterparts. For example, nanostructures’ huge surface area to volume ratio make them not only more reactive and but uniquely applicable for next-generation devices, including for implantable CMOS. This large surface area is just one of the many factors that alter nanostructures’ biological interfaces. Other aspects include their size, shape, surface functionality, charge, composition (organic, inorganic or hybrid), aggregation, solubility. Because of the widely tunable sizes and compositions, ENs can dynamically modify under different biological and environmental conditions, thus limiting options for uniform nano-bio interactions and standardization.
Abstract: The objective of this project is to establish a robust, rapid throughput and high-content screening platform to study biological interactions of ENs implemented on a beyond-CMOS substrate, including their potential toxicities due to their unique physico-chemical properties at the nano-scale. Towards this objective, we propose a multi-faceted exercise beyond the traditional singular-focus efforts involving a multi-disciplinary group of researchers from nanoengineering, nano-biophysics, nanochemistry and toxicology. An over-arching goal is to develop a new approach of scientific integration where nano-ESH is an integral part of EN design rather than a post facto add-on.
