Gut Microbiome Metabolomics Interlaboratory Program

Ongoing
On behalf of the Biosystems and Biomaterials and Chemical Sciences Divisions at the National Institute of Standards and Technology (NIST), we would like to thank you for your interest in our new Gut Microbiome Metabolomics Program. As part of the larger NIST Microbiome Program, this metabolomics
Picture for Hardness and Coating Thickness Standardization and Measurements Project Including Equipment and Standards Organizations

Hardness Standardization and Measurements

Ongoing
DESCRIPTION Purpose: Provide measurement traceability for the Knoop, Rockwell, and Vickers hardness scales and for coating thickness measurements that are based on magnetic methods. Goals: Harmonization of hardness and coating thickness testing protocols, in pursuit of reduction of measurement

HDX-MS for Biopharmaceutical Analysis

Ongoing
Intended Impact This project is designed to improve, test, and validate hydrogen/deuterium exchange mass spectrometry (HDX-MS) metrology for the determination of dynamical properties of therapeutic proteins and glycoproteins. Objectives Explore structure-function relationships between glycan

Health Assessment Measurements Quality Assurance Program (HAMQAP)

Completed
Participants in the HAMQAP measured concentrations of nutritional and toxic elements, fat- and water-soluble vitamins, fatty acids, active and/or marker compounds, and contaminants in samples distributed by NIST.   Samples that represent human intake (e.g., foods, dietary supplements, tobacco) were

Hierarchical Materials

Ongoing
The STG develops the methods and metrology that will lead to the understanding of the structure-property relationships of hierarchical composites in real medical PPE or protective applications, which heretofore has been lacking. This work establishes in situ monitoring of advanced manufacturing

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 Rate Testing

Ongoing
This project involves sample geometry and metrological development for high rate servohydraulic testing. (Content to be uploaded soon)
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-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 of chemical identification and structure for complex biomolecules. Conventional IR spectroscopy, e.g., Fourier-transform IR (FT-IR) technology, can characterize proteins and other

Improved Benchtop Connectivity to Complex Microfluidic Devices

Completed
Intended impact Microfluidic devices with many fluidic and pneumatic inlets are difficult to connect to benchtop reservoirs and controllers. Many hours can be spent sorting, untangling, and connecting tubing to a single device. If one then finds that the device is not fully functional, the process
