Professor Matthew Green joined the faculty at Arizona State University in Chemical Engineering in 2014. His training as a synthetic polymer chemist and chemical engineer positions his research group to sit at the intersection of these disciplines with focused applications in health, the environment, and advanced materials. His laboratory is integrating macromolecular design with controlled synthesis techniques to produce hierarchical and multifunctional materials with particular interest in the interplay between electrostatic interactions and microstructure, interphase interactions, thermomechanical properties, and transport. These features can be used to tune the material properties for applications ranging from membranes for water purification or CO 2 capture to polymeric nanocomposites. Professor Green obtained a B.S. in Chemical Engineering and a B.S. in Chemistry at Virginia Tech in 2007, and a Ph.D. in Chemical Engineering in 2011 at Virginia Tech working with Prof. Timothy Long. Then, he worked as a postdoctoral researcher at the University of Delaware in the Chemical and Biomolecular Engineering Department with Prof. Thomas Epps III and Prof. Millicent Sullivan. He has received several awards, including the Young Membrane Scientist Award (2016) from the North American Membrane Society (NAMS), the NASA Early Career Faculty Award (2018), the Mayo Clinic-ASU Alliance Fellowship (2018), as part of the Mayo Clinic and ASU Alliance for Health Care Summer Residency Program, the Ford Faculty Fellowship (2018), and the NSF CAREER Award (2019).

N2 - Photocurable nanocomposites have tremendous potential in tissue engineering, advanced manufacturing, and structural, multifunctional materials. This project investigates the effect of silica (SiO2) nanoparticle loading content on the thermal, mechanical, physical, and morphological characteristics of the nanocomposite. An increased concentration of SiO2 nanoparticles causes a decrease in the gel fraction of the nanocomposite, which, at low nanoparticle loading, degrades the thermal and mechanical properties. However, further addition (>3.8 wtâ»%) causes an increase in the glass-transition temperature, Young's modulus, and ultimate compressive strength. The addition of the nanoparticles had no significant effect on the hydrophilicity according to water uptake experiments. Small-angle X-ray scattering experiments, in conjunction with scanning electron microscopy and transmission electron microscopy, indicated a multimodal particle size distribution and the presence of large-scale aggregates.
