Nanoparticle Assembly in Complex Fluids

Completed
Engineered nanomaterials are promising for technological and medical purposes. However, molecular mechanisms of toxicology are less known. This presents a problem and barrier for future innovation and applications as new nanomaterials are developed for healthcare where particles are intentionally
Nanoparticle Metrology

Nanoparticle Metrology in Complex Cellular Environments

Completed
Nanoparticle interactions with individual cells. Existing techniques to evaluate nanoparticle incorporation include ICP-AES or ICP-MS, which atomize entire samples (thousands of cells) and detect nanoparticles by quantifying the elemental composition. Bulk techniques provide general trends averaged

Nanoparticle Tracking for Fluidic Self Assembly (Archived)

Completed
Over the last few decades, scientists have developed a sizable library of nanoscale "building blocks." These nanoparticles have novel thermal, optical, mechanical, and chemical properties relative to their macroscopic counterparts, and organized assemblies of these components promise vast

Nanophononic Metamaterials for Thermoelectrics

Ongoing
About 68 % of the energy produced in the United States is wasted as heat lost to the environment. About a quarter of this lost heat is present at temperature gradients suitable for recovery with thermoelectric devices, which use the ability of semiconductors to generate electricity directly from

Nanoplasmonics and Three-Dimensional Plasmonic Metamaterials

Ongoing
Plasmonic materials are composed of metals and insulators that are ordered in geometric arrangements with dimensions that are fractions of the wavelength of light. Research groups are experimenting with a variety of geometric approaches, but all aim to exploit surface plasmons, which are light

Nanoscale, Element-Specific X-ray Imaging for Integrated Circuit Metrology

Ongoing
Industry roadmaps identify the characterization of nanoscale subsurface feature shape and composition as a measurement need for the semiconductor industry. However, IC interiors are difficult to probe post-manufacturing due to the presence of many close-packed and nanoscale subsurface features, of

Nanoscale Property Measurements by Atomic Force Microscopy

Ongoing
Over the past several decades, Atomic Force Microscopy (AFM) has advanced from a technique used primarily for surface topography imaging to one capable of characterizing a range of chemical, mechanical, electrical, and magnetic material properties with nanometer resolution. Such characterizations

Nanoscale Thermal Properties

Completed
It is known that at the nanoscale, composition and interface structure play important roles in determining the mechanical, thermal, and electrical properties of multiphase nanomaterials and nanocomposites. To probe the thermal properties of these heterogeneous nanomaterials, local thermal analysis

Nanostructures for Energy Conversion

Completed
Transportation is the single largest contributor to U.S. carbon dioxide emissions. Moving to an electrically powered transportation system that draws on sustainable energy supplies has the potential to lower transportation costs, reduce greenhouse gas emissions, and help further reduce the nation's
Layout of the Nanotechnology Xccelerator Reticle with 30 unique tiles occupying 41 different slots within the reticle.

The Nanotechnology Xccelerator

Ongoing
The Nanotechnology Xccelerator was announced on September 13, 2022 and was officially accepted for production at Skywater Technology Foundry using the Sky130 technology in Q1 2024. Sky130, which comes in both a conventional and open-source process design kit, is a 5-metal layer process. To

Nanotribology for Nanomanufacturing (Archived)

Completed
Friction and wear are major causes of mechanical failures and dissipative energy losses. These shortfalls account for a significant portion of the annual gross domestic product in the United States, amounting to approximately $800 billion in 2010. It is estimated that tens of billions of U.S

Nanotube Metrology

Completed
Single-wall carbon nanotubes (SWCNTs) are a tubular form of carbon consisting of a single shell of sp2 bonded carbon with a nanometer scale diameter that have many predicted properties superior to other available materials. However, every production technique for SWCNTs produces many different
Carbon Nanotubes imaged via Focused Ion Beam Scanning Electron Microscope.

Nanotube Quality Control

Completed
Thermogravimetric analysis (TGA) is widely used to gather data on nanotube chemistry. By monitoring weight loss as a function of temperature, one can determine decomposition kinetics and use this data to closely approximate the distribution of impurities present in a few milligrams of material

National Cybersecurity Center of Excellence

Ongoing
Established in 2012 through a partnership between NIST, the State of Maryland and Montgomery County, the NCCoE is dedicated to furthering innovation through the rapid identification, integration and adoption of practical cybersecurity solutions. About the Center The NCCoE is a part of the Applied

National Earthquake Hazards Reduction Program (NEHRP) Coordination

Completed
Objective - To support NIST's statutory Lead Agency role of coordinating National Earthquake Hazards Reduction Program (NEHRP) research and implementation activities and to provide leadership and management support for the Interagency Committee on Seismic Safety in Construction (ICSSC). What is the

National Software Reference Library

Ongoing
The National Software Reference Library (NSRL) is designed to collect software from various sources and incorporate file profiles computed from this software into a Reference Data Set (RDS) of information. The RDS can be used by law enforcement, government, and industry organizations to review files
weighing device

National Type Evaluation Program (NTEP)

Ongoing
NTEP requires industry to submit prototype weighing devices for evaluation to determine whether or not it meets the uncertainties which are related to tolerances associated with the intended final use in the marketplace. All devices sold in the United States for "legal for trade" purposes must pass

National Windstorm Impact Reduction Program Coordination

Ongoing
Objective - To support NIST's statutory Lead Agency role of coordinating National Windstorm Impact Reduction Program (NWIRP) research and implementation activities. What is the new technical idea? This project supports coordination, management, and leadership of the National Windstorm Impact
