Facilities & Capabilities

The RTNN brings together comprehensive shared user facilities and over 100 complementary faculty research programs at the three major research universities within the network. RTNN technical capabilities span nanofabrication and nano-characterization of traditional hard, dry materials (e.g., 2D and 3D nanomaterials, metamaterials, photonics, and heterogeneous integration) and emerging soft, wet materials (e.g., tissue, textile, plant, and animal nanomaterials). The RTNN connects you with expert technical staff and faculty to provide:
  • Training for users to independently operate equipment.
  • Fabrication and analytical services.
  • Consultation, collaboration, and support for process and instrumentation development.
  • In-person and web-based workshops and interactive demonstrations on state-of-the-art techniques within the network.
Contact the our staff at rtnanonetwork@ncsu.edu to discuss how RTNN can help you. RTNN technical facilities offer a diverse set of capabilities to its users, including:

Local Resources

Molecular Microscopy Consortium (MMC) This consortium is a partnership between NIEHS, Duke University, and the University of North Carolina at Chapel Hill. The mission of the MMC is to enable the use of single particle cryo-electron microscopy (cryo-EM) and other tools in molecular microscopy to researchers across North Carolina. Cryo-EM is increasingly being used to determine the structure of macromolecules at atomic resolution. Research, Engagement, and Capabilities Hub of North Carolina ( REACH NC ) REACH NC is a web portal that enables users to search, browse, and find thousands of experts and assets within North Carolina higher education and research institutions. North Carolina Small Business and Technology Development Center ( SBTDC ) The SBTDC is the business and technology extension service of The University of North Carolina and is committed to providing knowledge, education, and other supportive resources that enable existing small and mid-sized businesses, emerging entrepreneurs, and local / state leaders to innovate and succeed.
