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.


Professor Majumdar will serve as the chair of the the Secretary of Energy Advisory Board (SEAB)

Posted on Tuesday, October 5, 2021

The U.S. Department of Energy (DOE) announced the new members of the Secretary of Energy Advisory Board (SEAB). Professor Majumdar will serve as the chair of the advisor board. This precedent-Setting diverse group of experts will provide advice and recommendations on departmental priorities as DOE is playing critical roles to help create a clean energy economy with millions of well-paying jobs, elevate environmental justice, invest in fundamental science and engineering research, and keep our nation secure.


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!


America needs a new hydrogen economy to tackle climate change

Posted on Sunday, August 29, 2021

Recently, professor Majumdar and his colleagues published a commentary on Joule which discussed the framework for a hydrogen economy with its important role in tackling climate change. It offers a systems view of a hydrogen infrastructure that includes production, transport, storage, use, and its economic viability. See media coverage here.


Group hike @ Stevens Creek!

Posted on Wednesday, August 25, 2021

On Sunday, we had an excellent group hike at Coyote Ridge Trail at Stevens Creek. The weather is wonderful. We had Chipotle after the hike. Our dear friend, Ferb, enjoyed the hike too but felt a little bit tired!


Ze passed the PhD defense! Congratulations!

Posted on Sunday, July 25, 2021

Ze Zhang passed her PhD defense with the thesis title "nanoscale imaging of photoexcited states using electron microscopy". Now she has graduated as a PhD in Mechanical Engineering with a minor in Physics. Congratulations!


Group hike @ Pulgas Ridge!

Posted on Monday, June 28, 2021

We had an excellent group hike at the Dusky-Footed Woodrat and Cordilleras Trails in Pulgas Ridge Open Space Preserve. This is our second hike after the pandemic. We then enjoyed Chipotle Mexican food at Arun's house after the hike. Our dear friend, Ferb, came with us again!


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.


Group hike @ Spring Ridge Trail to Windy Hill!

Posted on Monday, June 7, 2021

We had a wonderful group hike at the Ridge Trail to Windy Hill on Sunday, the first one after the pandemic! We enjoyed the beautiful scenery of the bay at the top of the hill, and the deep dish pizza after the hike at Arun's house. Our good friends, Leo and Ferb, enjoyed the pizza, too!


New custom built high pressure photoreactors!

Posted on Monday, May 24, 2021

We have a two new high pressure photoreactors! One photoreactor is capable of 10 bar pressure while the other can reach pressures of up to 100 bar. These photoreactors will be used for our photocatalytic methane to methanol project sponsored by the U.S. Department of Energy National Energy Technology Laboratory (DOE NETL). See details here.


Richard Randall has been awarded the NSF Graduate Research Fellowship. Congratulations!

Posted on Tuesday, March 23, 2021

Richard Randall has been awarded the NSF Graduate Research Fellowship which is a national competition run by the US government. The fellowship will allow Richard and the lab greater freedom to pursue projects of interest which have potential impact to the world. As a first-year PhD student, Richard will start his exploration in the energy field, especially the area of low-carbon industrial heating, with the support of the NSF fellowship. Congratulations!


Jimmy's paper on metal oxides for chemical looping hydrogen production published in Cell Reports Physical Science!

Posted on Monday, March 22, 2021

Our group's work on computational discovery of metal oxides forchemical looping hydrogen production has been published in Cell Reports Physical Science. We use CALPHAD, experiments,and technoeconomic analysis to study the water conversion capability of metaloxides, and report the discovery of oxides with yields up to eight times those of state-of-the-art oxides. Jimmy Rojas is the first author of the paper and Professor Majumdar is the corresponding author. Congratulations!

Posted on Thursday, March 11, 2021

Our group's work on photoabsorption imaging at nanometer scales using secondary electron analysis has been published in Nano Letters and selected as journal cover. We introduce photoabsorption microscopy using electron analysis and demonstrate spectrally specific photoabsorption imaging with sub-20 nm spatial resolution using silicon, germanium, and gold nanoparticles. Ze Zhang is the first author of the paper and Professor Majumdar is the corresponding author. Congratulations!

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!”
