I'd expect DuPont, BASF, Apple, Google, Intel, IBM, GE, Kodak if any of their labs remain, any number of biotech labs like Genentech might have that are sufficiently mat-sci adjacent, all of the major of universities; MIT, Harvard, etc. Any of the national labs. Sandia, Lawrence Livermore, whichever are appropriate. It's just that whole DEA and red phosphorus being a meth precursor making it difficult. Yay, war on drugs.
