nanoHUB.org is arguably one of the most successful science gateways funded by the National Science Foundation (NSF). It is the cyberinfrastructure that supports the Network for Computational Nanotechnology (NCN), currently serving over 240,000 users annually in 172 countries worldwide. It features a range of resources including seminars, online courses, short courses, fullfledged tool-powered curricula, and over 260 online simulations and modeling tools. nanoHUB functions as a scientific cloud where users cannot only design and run their tools but also provide a worldwide audience access to these tools with no installation or minimal infrastructural requirements on the users ' part.

BackgroundThe Network for Computational Nanotechnology Cyberinfrastructure Node (NCN CI) is responsible for the operation and support of the cyber-platform nanoHUB.org, serving a large scientific community centered around the nanoscience and nanotechnology fields. The word "community" is constantly on our minds. One definition of community is a "body of persons of common and especially professional interests scattered through a larger society. 1 " For us, this means we have a challenge of supporting a variety of community members, with varying viewpoints and needs; generally many wish to participate and utilize nanoHUB while a significantly smaller subset contribute to our online facility for that community. The staunchness of policy we set, the degree to which we enforce it, and the features we choose to make available are under constant examination: Are we making decisions that selectively encourage some members of the community while alienating others? Is the community we serve only those who agree with the policies we set, or do we need to look at setting policies that do not unnecessarily exclude well-respected members of the nanoscience and nanotechnology fields? nanoHUB has a significant ten year history of data and experience. nanoHUB users exceed 260,000 annually and access a portfolio of over 4000 resources contributed by over 1,000 authors, including over 300 simulation tools contributed by 411 software authors and developers. Such broad use and a large, vibrant community provide continued opportunities for growth, but careful management of policies and processes is necessary to anticipate and meet associated challenges.
More than 170,000 users annually in 172 countries use nanoHUB.org for web-based access to simulation programs as well as a vast selection of related content, including online presentations and lectures, teaching materials, curated topic pages, podcasts, and downloads. With over 2500 resources including over 200 simulation tools, the science gateway nanoHUB.org is the world's largest nanotechnology user facility. Over 10,000 research and educational users utilized nanoHUB simulation programs to run over 364,000 simulations last year.In academic year 2009-10, nanoHUB.org content was used in 150 undergraduate and graduate courses at 97 institutions. From the time of its inception through the beginning of 2011, nanoHUB.org has been cited 719 times in the literature. A detailed analysis of these citations indicates a dual use of nanoHUB content in both education and research, with educational tool usage by researchers and research tools migrating into the classroom. By leveraging existing capabilities, we have developed the Assembly of Basic Applications for Coordinated Understanding of Semiconductors (ABACUS) suite of simulation tools and supporting educational content that can serve as an aid to an introductory semiconductor course. ABACUS serves as a one-stop-shop for students and teachers to enable rapid access to the critical elements needed in the introduction to semiconductor devices.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
