BO has been deployed for the optimization and discovery of many different materials in the lab or a computer simulation, including nanoporous materials, nanoparticles, light emitting diodes, carbon nanotubes, photovoltaics, additively manufactured structures, polymers, thermoelectrics, antimicrobial active surfaces, quantum dots, 42 luminescent materials, catalysts, 44-47 thin films, and solid chemical propellants. More, BO has been used to optimize processes to synthesize materials and chemicals or to employ materials for an industrial-scale task.
