Sustainability by Design: A Framework for Emerging Materials
Novel materials have immense potential to significantly improve the functional performance of current and future technologies. Sustainability by design is a framework that aims to ensure that emerging materials are able to met (or even exceed!) desired performance metrics while also being safe to humans and the environment. This approach precludes the potential realization of adverse unintended consequences. The framework is established on the premise that material structure and physicochemical properties serve as a design handle to manipulate and tailor the desirable and undesirable outcomes. Structure-property-function (SPF) and structure-property-hazard (SPH) relationships are determined by establishing robust relationships between specific materials structure-property parameters and the desired function and inherent hazard.

Development of Parametric Relationships
The development of robust SPF and SPH parametric relationships requires 1) systematic modification of the material structure, physical and chemical properties followed by 2) comprehensive characterization of those properties, including the desired function and hazard response profiles, and 3) identification of statistically significant correlations between the data collected. This research thrust involves development of controlled treatment methodologies, utilization of numerous techniques to fully characterize all aspects of the material, and application of multivariate statistical analysis to establish robust relationships to inform future sustainable design of nanomaterials.

A Systems Approach to Nanomaterial and Nano-Enabled Product Design
The unique properties achieved by engineering materials at the nano-scale have inspired innovative applications with the potential to positively influence society and the environment. Biological and chemical sensors, therapeutic and drug delivery, and advanced water treatment technologies are just a few examples. Yet, the benefits realized through nano-enabling products are not without impacts that manifest across the life cycle. Example upstream impacts include metal mining and refining processes and synthesis of nanomaterials while downstream examples include human and environmental exposure to nanomaterials upon release from the product. The impact-benefit ratio (IBR) take a systems approach to quantifying the potential realization of net life cycle benefits.
