Fundamentals of Deformation

Ongoing
• We have provided general users from industry, academia and national laboratories with a completely new class of X-ray imaging techniques for materials studies (ultra-small-angle X-ray scattering imaging), that we developed from basic concept to DOE-supported operations at the Advanced Photon
qubit

Future Computing Systems and AI

Ongoing
Electrons confined in arrays of semiconductor nanostructures, called quantum dots (QDs), are a promising quantum computing approach. Due to the ease of control of the relevant parameters, fast measurement of the spin and charge states, relatively long decoherence times, and their potential for

Future Directions for Magnetic Sensors

Completed
Bringing new or improved magnetic sensors to market requires modeling for rapid assessment of the effect of new designs or improved materials properties. To this end, we are investigating the fundamental properties of a new class of magnetic sensors that is rapidly displacing ones based on older
The NIST Quasi-Deterministic Framework

Future Wireless Communications Systems and Protocols

Ongoing
​ Millimeter wave Communication Systems and Protocols 5G and beyond wireless communication systems make use of the Millimeter-Wave (mmWave) band. While this band offers unprecedented throughput thanks to the large bandwidth available, it also suffers from larger propagation loss compared to the sub
Electron microscopy images

GaN Nanowire Growth

Ongoing
Selective epitaxy: We have demonstrated that the diameter and placement of nanowires can be controlled by using silicon nitride (SiNx) masks on top of MBE-grown buffer layers (see figure). With electron beam lithography, several patterns with 3 mm die size that provide over 100,000 controlled

GaN Nanowire Metrology and Applications

Ongoing
GaN Nanowire LEDs: Our selective epitaxy methods and dopant characterization techniques have enabled fabrication of arrays of nanowire LEDs with controlled location and spatial layout. This development is complemented by modeling of the carrier flow and recombination. These LEDs were combined to

Gas Concentration Standards Supporting Atmospheric Monitoring

Ongoing
NIST develops suites of SI-traceable, amount-of-substance, primary gas standard mixtures (PSMs) for key trace and greenhouse gas species to provide traceability to the International System of Units for a range of user communities. Standard Reference Materials (SRMs), certified to the PSMs, are
two-capillary viscometer

Gas properties for flow metering

Ongoing
NIST has two on-line databases that include accurate gas viscosity values: SEMIPROP - NIST Standard Reference Database 134 - for selected semiconductor process gases NIST Chemistry WebBook - for heat transfer fluids, components of air, components of natural gas [Note: as of February 2014, the NIST

Gene Delivery Systems

Ongoing
Viral Vectors Viral vectors are a critical tool for delivering DNA or RNA into patient’s cells. Common viral vectors for gene therapy include adenovirus, lentivirus, and adeno associated virus. Administration of viral vectors can occur in vivo or ex vivo , such as for adeno associated virus or

Genome in a Bottle

Ongoing
Consortium goals: The Genome in a Bottle Consortium is a public-private-academic consortium hosted by NIST to develop the technical infrastructure (reference standards, reference methods, and reference data) to enable translation of whole human genome sequencing to clinical practice and innovations

Genomics of Electronic Materials

Ongoing
We approach this multidimensional characterization problem by developing measurement-based techniques to rapidly quantify all of the relevant properties of thin-film materials, interfaces, and microelectronic structures. We make extensive use of finite-element simulations, as well as linear and non

Glass Evidence Analysis

Ongoing
Quantitative XRF Glass Database Recent research efforts in the forensic trace field have focused on the development of databases to assign a significance to forensic evidence (i.e., to report the strength of an association or exclusion). In the forensic analysis of glass using µ-XRF, samples are

Glycan Standard Reference Materials

Ongoing
Now Available A glycan-based NIST Standard Reference Material ( SRM 3655 Glycans in Solution ) supports the biomanufacturing and protein therapeutics communities with a set of 13 individually-bottled, pure glycoforms including those most commonly observed as N-linked glycans on therapeutic

Graphene

Ongoing
Two remarkable features of graphene that are opening avenues to multiple applications are its high transport carrier mobility and the broad tunability of its electronic properties. Graphene charge carriers can be tuned continuously from negative carriers (i.e., electrons) to positive carriers (holes

Grasping, Manipulation, and Contact Safety Performance of Robotic Systems

Ongoing
Objective To provide performance metrics, test methods, and associated measurement tools to support next-generation robotic systems having human-like dexterity and force control characteristics. Technical Idea The force sensing and compliance capabilities used in collaborative robots to prevent

GReenhouse Gas And Air Pollutants Emissions System (GRA2PES)

Ongoing
The GReenhouse gas And Air Pollutants Emissions System (GRA2PES) uses publicly accessible GHG emissions activity data across multiple economic sectors, including energy production, manufacturing, transportation, agriculture, and land use, among others. The initiative involves the development of
Scrubber cropped

Greenhouse Gas Emissions and Transport

Completed
This project develops a high-accuracy reference system for near-industrial-scale CO2 measurements, providing a framework for low-uncertainty emissions data and improving atmospheric dispersion models to reduce uncertainties in greenhouse gas source predictions.
