 IMASC Overview

The core of the IMASC research approach is to integrate fundamental studies of model systems with the design, synthesis and testing of mesoporous catalysts spanning a vast range of pressures, temperatures and materials complexity. Theory and experiment are being combined to establish and test general principles that control reactivity and selectivity. Our team focuses on metallic alloy catalyst materials that have dual functionality.  The principal design feature of the catalyst material is to combine a minor amount of active metal that facilitates creation of reactive intermediates with a less active majority phase that transforms these intermediates to desirable products with high selectivity. IMASC research, based on active and inclusive management, is strategically organized into three Focus Areas to tackle some of the most important energy challenges facing the nation.


Introducing IMASC Focus Area 2 Lead

Dr. Maria Flytzani-Stephanopoulos is Distinguished Professor and the Robert and Marcy Haber Endowed Professor in Energy Sustainability in the School of Engineering at Tufts University. She directs the Tufts Nano Catalysis and Energy Laboratory. Pioneering work from her lab has demonstrated the use of single-atom catalysts for key reactions of interest to fuel and chemicals processing, aimed at the development of more efficient and sustainable processes. Since 2002, she serves as Editor of Applied Catalysis B: Environmental, and is also an associate editor of Science Advances. She is a member of the National Academy of Engineering, and a Fellow of the AAAS and the AIChE. As a key partner of the EFRC/IMASC, her team is focusing on dilute copper and gold alloy catalysts and developing state of the art in situ liquid reaction capabilities using a high T/P ATR-IR cell coupled with HPLC.

Young Investigator's Column

We are pleased to introduce Dr. Fanny Hiebel, a postdoctoral researcher in the Friend Lab at Harvard. She is one of the experimentalists in IMASC. She recently shared her insights in the form of a Q&A.  

  • How much interaction do you have with other members of IMASC?

Working at an Energy Frontiers Research Center has been ideal in terms of fostering collaborative work. The IMASC is composed of researchers from different backgrounds and institutions working towards one common goal. We meet about once a week and get to exchange on diverse aspects of the center’s research. This was a great opportunity for me to learn about a variety of techniques and scientific approaches. IMASC also provided a framework for collaborations with theorists -- Dr. Matt Montemore and Dr. Wei Chen, postdocs with Prof. Tim Kaxiras -- which allowed us to produce high value results by combining scanning tunneling microscopy (STM) and density functional theory simulations.  Read more
