"creating ideal high-density nanotube structures is difficult, overcome using machine-learning to model, characterize, simulate, predict nanoparticle catalyst growth during nanotube fabrication... keeps fabrication cool/ connected... future: not all of those 100 billion nanoparticles will grow nanotubes, and we are working to discover which ones act as seeds, and why"
