Excited to share our article on recent advances in TURBOMOLE for periodic & molecular DFT! #compchemsky

Special milestone: some of the final results from my PhD are now published + my 10th paper
Grateful to Prof. Marek Sierka & amazing collaborators for the oppurtunity!

Our work on modeling extended defects in MoS2 is now out in Small!

onlinelibrary.wiley.com/doi/10.1002/...

We show how size and chemical environment affect nanopore geometry in MoS2, changing pore shapes from irregular to triangular.

Size and Chemical Environment Control Nanopore Geometry in 2D MoS2: From Irregular to Triangular Defects

This work addresses a longstanding challenge of developing a predictive framework for defect topologies in 2D MoS2. By combining density functional theory calculations, kinetic Monte Carlo simulation...

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

Manas Sharma @physwhiz.bsky.social · Jun 28

but haven't checked the performance for different charges though so can't say about that

Manas Sharma @physwhiz.bsky.social · Jun 28

So will DFT lmao🤣
You need to find the spin that gives the lowest energy, just like DFT. What I will agree with though is that for compounds out of the training set it may not give the correct spin for the ground state.

Manas Sharma @physwhiz.bsky.social · Jun 28

What I like the most about the UMA (OMol25) model is that it can take spin and charge as the input. This is a game changer as it allows simulating a large vareity of compounds with correct spin multiplicity. Seems to be quite accurate uptil now in my tests.

Recently, MetaAI released the OMol25 dataset and the UMA model — a powerful foundation model for #compchem community.

Now, you can try UMA and 16+ other MLIPs (incl. MACE) on your own systems with an app that I developed: MLIP Playground👇👇
