What is Nanotechnology?

A nanometer is one-billionth of a meter—25,000 times smaller than the width of a human hair, 200 times smaller than a typical virus, about the size of 3-4 atoms laid end-to-end. At that tiny scale, matter can exhibit some strange, new behaviors. Nanotechnology is all about harnessing those behaviors to create new devices and materials. Imagine a new material that is 100 times stronger than steel, with only one-sixth the weight! Imagine making a transistor out of a single molecule! Imagine molecular machines that practice personalized nanomedicine by repairing damaged cells. These are still dreams, but scientists and engineers in laboratories all over the world are working to make these dreams a reality—to turn the promise of nanoscience into technologies for the benefit of human society.

What is nanoHUB?

The nanoHUB is a rich, web-based resource for research, education and collaboration in nanotechnology. The nanoHUB hosts hundreds of resources which will help you learn about nanotechnology, including Online Presentations, Courses, Learning Modules, Podcasts, Animations, Teaching Materials, and more. Most importantly, the nanoHUB offers simulation tools which you can access from your web browser, so you can not only learn about but also simulate nanotechnology devices.

Resources come from hundreds of contributors in the nanoscience community, and are used by thousands of users from all over the world. Most of our users come from academic institutions and use nanoHUB as part of their research and educational activities. But we also have users from national labs and from industry.

Our Mission

The nanoHUB was created the NSF-funded Network for Computational Nanotechnology (NCN). The NCN is a network of universities with a vision to pioneer the development of nanotechnology from science to manufacturing through innovative theory, exploratory simulation, and novel cyberinfrastructure. NCN students, staff, and faculty are developing the nanoHUB science gateway while making use of it in their own research and education. Collaborators and partners across the world have joined the NCN in this effort.

Join Us

Take a tour of the nanoHUB and see how you can use our infrastructure to further your own research and educational activities. Create your own account. It’s free and will give you access to our online simulation tools, learning modules, and more. Become a contributor by uploading your own presentations and simulation tools onto nanoHUB for others to share. Ask a question in our community forum, and let the community help you out.

Research

The nanoHUB is designed to be a resource to the entire nano-community, but its creation is being spearheaded by the three themes of the NCN: Nanoelectronics, NEMS/nanofluidics, and nanomedicine/biology. An effort in nanophotonics is also being seeded. The NCN seeks partnerships with center-scale efforts to broaden the scope of the nanoHUB o other fields of nanoscience.

Computation and software is a cross-cutting theme in the NCN that connects computer scientists and applied mathematicians to problem-driven scientists and engineers, to address large scale problems and develop community codes for nanotechnology.

Look at current and former NCN Principal Investigators and NCN associates to see what we are working on.

The FBI has chosen the National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign to host a new law enforcement cybersecurity research center.

The bureau said it would provide $3 million to support the first two years’ operation of the National Center for Digital Intrusion Response. The new center represents an expansion of the FBI’s existing work with the university, which also receives funds from other federal agencies to carry out cybersecurity research and development.

“This effort will benefit the scientists, engineers and other researchers who use cyber-resources at NCSA and other federal centers by protecting the cyberinfrastructure they rely on,” said NCSA Director Thom Dunning in an FBI press statement released earlier this month. “NCSA and the University of Illinois have been and continue to be at the forefront of developing, deploying and safeguarding advanced computing resources.”

The bureau said the state university’s IT security scholars would work with FBI cybersecurity specialists to understand what new capabilities are required to better detect and investigate cyberattacks, develop new tools and ensure that FBI agents in the field can use them effectively.

The NCSA has 22 years of experience in protecting high-performance computers from cyber attacks, the bureau said. The work has included developing software for data analysis, visualization, collaboration and communication, the FBI said.

“It’s about understanding what’s needed to solve cases and protect the cyberinfrastructure which is so critical to our national way of life,” according to a prepared statement by Von Welch, leader of NCSA’s Security Research and Development division and a member of NCDIR’s leadership team. “NCDIR has evolved from the decade-long engagement NCSA has had with the FBI, which has included working with them on multiple investigations, often leading to arrests.”

The bureau’s expansion of its work with the university team reflects changes in the patterns of crime and national security threats, the FBI said.

“While cyberattacks were once considered a specialized niche in law enforcement, today there are digital aspects to many crimes and national security threats; all investigators must be able to pursue criminals operating in cyberspace,” the FBI said. “NCDIR will provide training, including intensive summer workshops, so all FBI agents have the opportunity to use these new tools in the field.”

According to a bureau description of the NCSA’s work, the university’s IT security team leads the National Center for Advanced Secure Systems Research and collaborates with other scholars via the Information Trust Institute.

NCSA has been funded by the National Science Foundation and other federal agencies to develop IT security tools and projects such as:

• MyProxy, a tool for grid credential management;
• Framework for Log Anonymization and Information Management, an app that facilitates sharing of log data among secure systems;
• GridShib, at tool that supports identity federation for grids;
• Trustworthy Cyberinfrastructure for the Power Grid; and
• Illinois Terrorism Task Force’s First Responder’s Credentialing.

“We are very excited about the opportunities offered by partnering with such knowledgeable and trusted colleagues,” said John H. Stafford, acting special agent in charge of the FBI’s Springfield division.

“NCSA brings to the table an extraordinary level of experience in navigating the complex landscape of the Internet, which NCDIR will leverage to advance the capabilities of the FBI,” Stafford said. “This will serve to bring to justice not only sophisticated criminal organizations, but also to better defend cyberspace against terrorist attacks and hostile intelligence organizations.”
