NCAL: Multiaxial Material Performance

Ongoing
Modern metal forming methods are designed and optimized using digital models of specific manufacturing operations. These models rely on a precise understanding of the mechanical behavior of sheet materials as they undergo multiaxial loading out to large plastic strains without failure (necking or...

NCAL: NIST Center for Automotive Lightweighting

Ongoing
The ongoing development of new, advanced lightweight materials presents opportunities for the USA automotive industry to produce better, more reliable and less expensive products provided the new materials can be efficiently manufactured. The use of lightweight materials in automobiles, such as...

NCAL: Quantifying Crystallographic Texture and Phase Fraction

Ongoing
Predicting the deformation and force response of a polycrystalline material with the level of accuracy needed by today’s manufacturers requires knowledge of the aggregate deformation and force response of all the grains in the material. Polycrystalline materials will respond differently depending on...

NCAL: Tension-Compression Testing

Ongoing
The inability to predict the mechanical behavior of new automotive alloys during forming has generated strong demand in industry for more advanced material models and test methods necessary to calibrate them. Industry is particularly interested in modeling the behavior of advanced sheet metals...

NIST Combinatorial Methods Center (NCMC)

Completed
Established in 2002, the NCMC combines pioneering research and customer engagement to foster wide-spread adaptation of combinatorial and high-throughput methodologies. NCMC research addresses key challenges faced by polymer researchers who want to employ combi. In particular, the NCMC creates new...

NIST Materials Resource Registry

Ongoing
The MRR is a comprehensive inventory of high-level data collections, repositories, databases, tools, software, and services useful to materials research and design but located anywhere in the world. Its specialization for Materials Science is in the domain-specific metadata and vocabulary it can...

NIST Standard Reference Simulation Website

Ongoing
Molecular simulations, in particular Monte Carlo Molecular Simulation and Molecular Dynamics Simulation, are methods for computing the properties of some kind of system, for which the intermolecular interactions are specified via mathematical relationships derived from statistical mechanics. Since...

OOF

Ongoing
The OOF project is a software development project designed to make advanced computational modeling capabilities available to materials science researchers who are not themselves computational experts. Researchers bring domain expertise from materials science to assist in building high-quality finite...

Open Port Liquid Interface Mass Spectrometry

Ongoing
Rapid screening for chemical traces of explosives and narcotics is widely used to support homeland security and law enforcement. These target compounds span a range of physicochemical properties from organic to inorganic, with preferential ionization pathways in both negative and positive mode...

OpenCALPHAD

Ongoing
Thermodynamic data are essential for the understanding, developing, and processing of materials. The CALPHAD technique has made it possible to calculate properties of multicomponent systems using databases of thermodynamic descriptions with models that were assessed from experimental data. The OC...

Optical and Optoelectronic Materials Characterization

Ongoing
Today's electronics have reached a point where sheer computation power has combined form and function as the key driver of large consumer markets. The demand for portable and pervasive electronics with greater functionality promises significant changes over the next decades in how society interacts...

Optical Probes of 2D Magnetic Phenomena

Ongoing
The unique measurement capabilities developed in this Project enable diffraction-limited, optical spectra (both Raman and photoluminescence) to be collected and analyzed as a function of laser energy, polarization, temperature, magnetic field, and device parameters such as current load and back...

Particles, Tubes, and Colloids

Ongoing
Description A highlight of the PTC project is our success in purification of well-defined SWCNT populations using liquid phase separation methods. Although we use multiple techniques and methods, ion exchange chromatography, rate-zonal and isopycnic ultracentrifugation, size exclusion chromatography...

Personal Body Armor

Completed
To quantify the impact of mechanical degradation on ballistic fibers, NIST developed a novel device for controlled folding of yarns and woven fabrics. In addition, we developed test protocols that employ single fibers to assess the effect of folding using a recently developed modified single fiber...

Physical Infrastructure: Connections

Completed
The NIST Physical Infrastructure Program will provide the critical measurement science needed to assess the condition of aging physical infrastructure and guide cost-effective strategies for its maintenance, repair, and replacement. Infrastructure management challenges in the U.S. have received...

Pipeline Safety

Ongoing
The U.S. operates more than 2.5M miles of natural gas, petroleum and hazardous liquid pipelines, crossing all 50 states and operated by more than 3,000 companies. Fluid hydrocarbon fossil fuels remain the world leading source of energy. The safest and most reliable means of transporting these fuels...

Polymer Formulations

Completed
Bringing new and optimized formulated products to market requires measurements that will allow rapid assessment of the structure and properties of multicomponent mixtures over large parameter spaces. To this end, we are developing microfluidic "lab on a chip" technologies that enable researchers to...

Polymer Mechanics

Ongoing
The mechanical behavior for polymers is very sensitive to the deformation rate of the impact test. Thus we are developing and applying several novel measurements that can study the mechanical response of the polymer at different deformation rates and at different material length scales. High-rate...
