nanoHUB.org is definitely a very important resource for research students. nanoHUB is world recognized. Its impact is global. Two weeks ago, I was in Switzerland giving an invited talk on the first inversion-mode gate-all-around III-V MOSFETs paper, and a graduate student came up and said he is taking a class of Professor Datta's through nanoHUB.
