It was a particularly rewarding collaboration with experimentalists Dr. Santhosh and Dr. Valavarasu at HPCL, and Dr. Amol Amrute at A*STAR.

It is fulfilling that Anand is now a budding Assistant Professor at the Motilal Nehru National Institute of Technology (MNNIT), Allahabad, while Swastik, Srinibas, and Rahul are successful PhD students at the University of Rochester, IISc, and Cornell University, respectively.

The project also involved former students Srinibas Nandi and Rahul Sheshanarayana, along with collaborators Santhosh Kotni and G Valavarasu from the Hindustan Petroleum Corporation Limited (HPCL), Amol Amrute from A*STAR Singapore, and Ambedkar Dukkipati from the Indian Institute of Science (IISc).

Overall, the proposed methodology opens new directions for accurate modeling of catalytic reaction mechanisms. The research was mainly done by former C V Raman Postdoctoral Fellow Anand Mohan Verma, PhD student Shivam Chaturvedi, and former project associate Swastik Paul, who contributed equally.

As part of this work, we also developed new algorithms, named automated reaction enumeration and elementary reaction identification, which enabled an exhaustive compilation of elementary reaction steps involved in CO2 hydrogenation.

This is opposed to the splitting of a hydrogen molecule into two atoms, which then add to CO2 or other species on the catalyst surface. The new mechanism was verified by quantum-mechanical calculations and can lead to the discovery of efficient pathways for CO2 and CO hydrogenation in the future.

What is noteworthy is that previous studies modeled only dozens, not even hundreds, of reactions. The proposed machine learning approach also revealed a new hydrogenation mechanism involving hydrogen atom donation.

Ananth Govind Rajan @ananthgr.bsky.social · 01/10/2026
The results demonstrate that even large networks containing hundreds of reactions can predict products incorrectly, and only the proposed approach agrees with experimental trends for CO2 conversion and methanol production on copper.

We developed a machine-learning-enhanced approach to enable kinetic modeling of massive reaction networks for CO2 hydrogenation, comprising about 10,000 elementary steps.

Ananth Govind Rajan @ananthgr.bsky.social · 01/10/2026
Understanding the mechanisms underlying CO2 hydrogenation is challenging because it involves thousands of elementary steps occurring simultaneously on catalyst surfaces.

Elated that our recent work has been published in Nature Communications! www.nature.com/articles/s41... Hydrogenation is a key process to convert carbon dioxide (CO2), a greenhouse gas, into valuable chemicals. It can help close the carbon cycle and potentially ameliorate global warming.

The work was led by recently graduated PhD student Pradeep Dhondi, and involved former postdoc Sagar Ghorai. Many thanks to the Anusandhan National Research Foundation and the Infosys Foundation for funding the work, and to C-DAC for providing access to the Param Siddhi-AI supercomputer.

We show that low edge charges sieve ions, but positive edge charges exclude boron, a difficult-to-remove contaminant. These design principles will enable the development of efficient, next-generation seawater desalination membranes for producing drinking water.

On the left is a schematic of an alkaline water electrolyzer. It shows aqueous KOH coming up from the bottom of the device. On the left side of the device are water molecules, shown as blue circles. H2 travels to the top of the device and OH- moves to the right through a separator. The OH- is converted into O2, shown as orange circles, and travels to the top of the device. The top of the device shows the flow of electrons. On the right is the simplified model geometry of the electrolyzer used in simulations, showing the cathode and anode both being 2mm wide and 100 mm long with 1mm of space between them.

Hi #compchem, Now calculate vibrational modes of a molecule using machine learning interatomic potentials (MLIPs) such as UMA (OMol), MACE OMAT-0, MatterSim, 7Net and many more on MLIP Playground (huggingface.co/spaces/Manas...) and yes there is a dark mode
