SUMMARY:Materials Exhibiting Biomimetic Carbon Fixation: Kinetic Analysis\, Mechanistic Insights\, and Material Design
DESCRIPTION:ChE Seminar Series Presents: \nDorsa Parviz\, Ph.D. \nDepartment of Chemical Engineering\, Massachusetts Institute of Technology \n Abstract: \nPopulation growth and climate change necessitate a paradigm shift from current chemical and materials production methods to more sustainable approaches with a negative carbon footprint. In view of this\, I will introduce carbon fixing materials (CFM) as a new synthetic platform that\, like plants\, utilize sunlight to photocatalytically reduce ambient CO2 and add to an ever-extending carbon backbone. First\, I will describe a mathematical framework enveloping the main functions of carbon fixing materials to answer basic questions about the kinetics regimes of operation\, photocatalytic requirements\, and limits of functional materials in CFMs. I will also present mechanistic insights on the photocatalytic reduction of CO2 to C1 intermediates as desired intermediates for producing value-added products from CO2. In the second part of my talk\, I will focus on state-of-the-art 2D nanomaterials and strategies for surface engineering these materials in the colloidal state\, addressing challenges in their characterization for applications in photocatalysis. \nBio: \nDorsa Parviz is a postdoctoral researcher at the Massachusetts Institute of Technology\, working with Prof. Michael Strano in the Department of Chemical Engineering. She earned her Ph.D. in 2016 from Texas A&M University under the guidance of Prof. Micah Green\, where she pioneered techniques for high-yield production of 2D nanomaterials\, investigated their colloidal interactions and assembly\, and designed tailored nanosheet-based polymer composites and 3D networks for structural and electrode applications. During her postdoc\, she developed carbon fixing materials at MIT\, establishing a high-throughput photocatalytic reaction screening system to accomplish this vision. In addition\, she has led the research on the preparation and characterization of biocompatible engineered 2D nanomaterials with tailored structure and properties for nanotoxicity studies at NIEHS Nanosafety Center. \nIf unable to attend in person\, please contact a.ramsey@northeastern.edu for the seminar link.
