NSF’s Convergence Accelerator is developing use-inspired solutions to address challenges aligned to the manufacturing, reuse and recycling of critical materials and products. Sixteen teams have been selected for the program’s Track I: Sustainable Materials for Global Challenges, and our team on “Sustainable Topological Energy Materials, or STEM, for Energy-efficient Applications” is very lucky to be one of them. Big congratulations and looking forward for a productive year of 2023.
