I am sending you some happy spam:</div>

that got me into chemistry because they can have interesting non-trivial topological realizations, including interpenetrations, linking, and that Riya is (very theoretically) braiding!</span></div>

<div dir="ltr" style="font-size: 16px;">Their topological diversity is surely less known than their potential applications though: Metal-organic frameworks are currently much studied for gas storage, adsorption, and separation. Think of methane/hydrogen storage,
carbon capture, flue gas separation. Properties that Hannah is helping machine learning models to predict. Whether metal-organic frameworks are going to help save the world or not, I'd say it’s a good day for applied topology!</div>
