Statement on Diversity and Inclusion

Our group is committed to creating a workplace and an environment that is supportive, inclusive and welcoming for all people, regardless of their race, ethnicity, nationality, religion, gender identity, sexual orientation and political beliefs. We believe that diversity of thought, experience and approach is an asset that enriches discourse and creates opportunities for all of us to learn different viewpoints from each other. We strive to create an environment that enables and empowers each one of us to reach our full potential.

Richard and his team won the XPrize Carbon Removal Student Competition. Congratulations!

Posted on Thursday, November 18, 2021

Lab member Richard Randall is part of the "Holocene Climate" team, a group that recently received a student award from the Musk Carbon Removal XPrize. This prize is part of the larger Carbon Removal XPrize competition running from 2021 to 2025, which aims to develop "negative emission" technologies to help mitigate climate change. The student awards are meant to help university teams compete in later rounds of the competitions against more established companies. Holocene Climate is a group of Stanford students who have worked to model and commercialize a novel direct air capture (DAC) technology since spring of 2021. Richard is one of their lead engineers.

We present the design and construction of an optical TEM specimen holder on Microscopy Today

Posted on Tuesday, October 5, 2021

We published a paper on Microscopy Today which describes our process for designing and fabricating an optical TEM specimen holder, highlighting important aspects of the design. We recently proposed combining spectrally selective photoexcitation with HRTEM to achieve sub-nanometer scale optical imaging, a technique we called photoabsorption microscopy using electron analysis (PAMELA). To realize PAMELA-TEM experimentally, we constructed a TEM holder with an optical feedthrough, capable of photoexciting materials with different wavelengths. Joel is the first author of this paper. Congratulations!

Jimmy passed his PhD defense! Congratulations!

Posted on Friday, June 18, 2021

Jimmy Rojas passed his PhD defense with the thesis title "GHG-Free Hydrogen Production". Congratulations! Jimmy's work focused on the production of green hydrogen. He studied chemical looping processes from both a theoretical (thermodynamic) and experimental point of view resulting in the finding of new materials and methodologies for water splitting. His work also encompassed a detailed technoeconomic analysis of multiple H2 production methods.

A Conversation with Bill Gates on Climate Change

Global Energy Dialogues 2021

Professor Majumdar had a insightful conversation with Bill Gates on how to avoid a climate disaster. The conversation focused on Bill Gates' new book on climate change, what he's learned about this complex and far-reaching challenge, and why he remains hopeful that we can overcome climate change.

Turn CO2 into oil at a cost of $2/gallon? “A lot of people think this is impossible,” says Majumdar, “but it’s not! Carbon free energy is almost cheap enough to take on this challenge in a meaningful way. And the race is on among scientists and engineers to make this happen!”

Our Lab

The Magic Lab now occupies 2000 square feet of space on two floors of Stanford’s Mechanical Engineering Research Laboratory. Our facilities have dedicated areas for wet chemistry, optics, cryogenics, and general electromechanical assembly, in addition to office and conference areas.
