spirit of a research university, nanoHUB-U courses aim to bring new advances and understanding from research into the curriculum; in addition, simulation (often from nanoHUB) are heavily included in the courses. Every effort is made to present courses in a way that is accessible to beginning graduate students with a variety of different backgrounds with a minimum number of prerequisites. The ideal nanoHUB-U course is accessible to any students with an undergraduate degree in engineering or the physical sciences. Courses include nanoelectronics, nanoscale materials, and nanoscale characterization. nanoHUB-U courses are now a part of
465:. For each system, a VNC server is pre-started for every session. When OpenVZ is used, that VNC server is started inside of a virtual container. Processes running in that container cannot see other processes on the physical system, see the CPU load imposed by other users, dominate the resources of the physical machine, or make outbound network connections. By selectively overriding the restrictions imposed by OpenVZ, it is possible to synthesize a fully private environment for each application session that the user can use remotely.

Approximately sixty percent of the citations stem from authors not affiliated with the NCN. More than 200 of the citations refer to nanotechnology research, with more than 150 of them citing concrete resource usage. Twenty citations elaborate on nanoHUB use in education and more than 30 refer to nanoHUB as an example of national cyberinfrastructure.

The nanoHUB-U online course initiative was developed to enable students to study a subject in a five-week framework roughly equivalent to a 1-credit class. No credit is given – quizzes and exams are simple and are intended to be aids to learning rather than rigorous tests for acquired skills. In the
