High Performance Crystal Plasticity

Ongoing
“Crystal plasticity” is a computationally intensive way of computing the behavior of materials undergoing large permanent deformations. Computation is very inhomogeneous: A large effort is expended everywhere, but only a small portion of the computational domain is doing anything interesting. We

High Resolution Atomic Spectroscopy

Ongoing
For many decades, the Atomic Spectroscopy Group at NIST has measured atomic data of vital use to astronomy and other fields using high resolution spectrometers that are found in few other places in the world. These include a 2-m path difference Fourier transfer (FT)spectrometer, a vacuum ultraviolet
Today, device performance needs to be evaluated to determine success of materials development. This project will advance metrology for magnetic materials and develop models to predict device performance.

High Speed Metrology for Magnetoelectronic Devices and Models

Ongoing
The U.S. Semiconductor industry is integrating ferromagnet-based microelectronic devices such as magnetic RAM (MRAM) into existing silicon-based technologies. MRAM has much shorter write times and higher write endurance than the embedded Flash currently used. These properties makes MRAM highly

High Throughput Thin-film Materials Science

Ongoing
There are many materials science problems that don’t have good modeling frameworks and exist in large design spaces. In these domains the best approach is to rapidly acquire data. To achieve this we can deposit metallic alloys as thin films with a range of composition (or less commonly processing

High-Frequency Electronics

Ongoing
This project supports the metrology of advanced electronic circuits and systems through many activities centered around accurate measurements and characterizations, improving device models and designs, enabling traceability of complicated electronics systems, and incorporating advanced technologies

High-Precision Isotopic Reference Materials

Ongoing
A new generation of multi-collector IRMS, utilizing both inductively coupled plasma and thermal ionization sample sources, is now capable of measuring isotope ratios with extremely high precision – a few parts in 10 6. This new measurement capability has caused a minor revolution in the use of

High-Precision Structural Measurements

Ongoing
On the instrumental and data processing side, we focus on improving the precision of structural information derived using transmission electron microscopy (TEM). Aberration-corrected scanning TEM enables direct imaging of atomic columns but the precision of column positions extracted from the images

High-Sensitivity IR Spectroscopy of Proteins

Ongoing
Infrared (IR) absorption spectroscopy has been widely used as a non-invasive, label-free characterization method for the chemical identification and structure of complex biomolecules. Fourier-transform IR (FT-IR) technology is commonly used to characterize proteins and other biological molecules

HML Organic Chemical Metrology Program Areas

Ongoing
The organic analytical facility, located on the second floor of the Hollings Marine Laboratory, consists of two laboratories with a combined area of approximately 215 m2. These two laboratories provide the space and instrumentation to achieve two main functions for NIST: (1) the determination of

Human Factor Guidelines and Accessibility

Ongoing
With the aging of America, increasing prevalence of chronic disease and growing immigrant and minority populations in the U.S., there is the real potential for both unintentional traditional and digital health-care disparities. Health information technology (HIT) holds significant potential to
