The Center for Integrated Nanotechnologies (CINT) is a Department of Energy/Office of Science Nanoscale Science Research Center operating as a national user facility at Los Alamos and Sandia National Laboratories. CINT is devoted to establishing the scientific principles that govern the design, performance, and integration of nanoscale materials. CINT users can access dedicated research capabilities in the Core Facility (Albuquerque) and the Gateway to Los Alamos (Los Alamos) to synthesize and characterize nanostructured materials, theoretically model and simulate their performance, and integrate nanoscale materials into micro-scale systems in a clean-room environment. Unique to CINT are Discovery Platforms™, modular, micro-laboratories designed and batch fabricated expressly for the purpose of integrating nano and micro length scales and for studying the physical and chemical properties of nanoscale materials and devices. CINT researchers also can have access to selected Los Alamos and Sandia capabilities in biosciences, microelectronics, nanofabrication and computing on a limited basis. Joint user proposals involving the Los Alamos Neutron Science Center and the National High Magnetic Field Laboratory are encouraged.
