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 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.

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!

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 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.

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 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 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 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 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!
