Indeed, I have a Mexican friend (I'm American) who when we met was a chemistry postdoc in CDMX. His entire focus (as a postdoc) is to examine chemical compositions of paintings and artwork (from pre-modern artifacts to Diego Rivera murals/frescos). Not sure where all the funding comes from but believe a lot of it is from the Mexican Gov for cultural and regional restoration efforts. A few years back him and a colleague traveled to San Francisco to analyze a multi-panel Rivera piece ("Pan American Unity" [1]) that was on display at (and owned) by City College San Francisco. The goal was to move the panels from CCSF to the SFMOMA [2] for display and their task was to make sure it could be moved properly to minimize damage. It was super cool to visit and see their workspace and tooling. For the mural itself - it's amazing and huge and recommend folks take a look if they can.
