Capillary condensation model - a web application

Our group has developed a capillary condensation model for soot aggregates in the recent years. Capillary condensation is an aging mechanism enabled by the fractal geometry of soot, which allows vapors to condense on particles even when their concentration is sub-saturated. Now, we release a web application that allows experimentalists to quickly estimate the amount of coating condensed through capillary and uniform condensation mechanisms

An unaccounted pathway for rapid aging of atmospheric soot

I recently gave a talk at the 2024 American Geophysical Union meeting about how capillary condensation of trace vapors on soot can lead to rapid activation of the particles. This condensation mechanism is currently unaccounted for in aerosol models, which leads to underestimation of the secondary impact of soot on climate. Check out my slides and the preprint of the manuscript here to learn more about soot aging through capillary condensation

Discrete element method model of soot aggregates

Our recent paper with Gennady Gor and Alexei Khalizov presents the first fully physical model for mechanics of soot aggregtaes. The model is based on the discrete element method and was able to reproduce AFM force spectroscopy experiments. The goal is to use this model to simulate restructuring of coated aggregates

How to run latexdiff in Github Actions

A tutorial that teaches how to automatically run latexdiff every time changes are pushed to Github. Latexdiff is a tool that can generate a document highlighting changes between two versions of a latex document, similar to the track changes feature in MS Word. Here I show how to automate diff file generation using Github actions and how this approach can be integrated with Overleaf
