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.

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!


Our work on nanometer-scale photoabsorption imaging published in Nano Letters and featured as cover!

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!


Professor Majumdar expressed his opinion on weather catastrophe prediction on the New York Times

Posted on Thursday, February 25, 2021

Professor Majumdar delivered an opinion article on the New York Times talking about how we can better predict weather catatrophes. This would involve new satellites and ground-based monitoring stations that feed their data to high-performance computers to predict events. Recent efforts are attempting to fill the predictive gap with a combination of physics-based and artificial-intelligence-based models.


Professor Majumdar hosted a conversation with Bill Gates on how to avoid a climate disaster

Posted on Thursday, February 18, 2021

Professor Majumdar hosted a conversation with Bill Gates focusing on Bill Gates' new book - How to Avoid a Climate Disaster, his efforts to investigate the causes and effects of climate change, and how the world can get to net zero in time. Stanford President Marc Tessier-Lavigne offered opening remarks.


Our work on sub-nanometer scale imaging published in APL and featured as cover!

Posted on Tuesday, Jan 26, 2021

Our group's work on sub-nanometer scale imaging of optical phenomena has been published in Applied Physics Letters (APL) and selected as journal cover. We propose an approach that combines spectrally specific photoabsorption with sub-nanometer scale resolution TEM of photoexcited electrons to directly visualize photoexcited states at the sub-nanometer scale. Ze Zhang is the first author of the paper and Professor Majumdar is the corresponding author. Congratulations!


Shang has graduated as a ME-PhD. Congratulations!

Posted on Monday, September 28, 2020

Shang Zhai has graduated with a PhD in Mechanical Engineering and a PhD Minor in Materials Science and Engineering at Stanford University. His PhD research is on splitting water and CO2 with iron-based oxides. The research topics cover materials design strategies, thermodynamic driving force and system technoeconomics.

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!”
