Biomaterials for Oral Health

Completed
NIST along with its partners has a long commitment to scientific excellence with demonstrated impact in improving the oral health of the public. NIST researchers are leaders in this field and create a community by engaging other researchers, industry, and regulatory agencies to address urgent needs

Combinatorial Approaches to Thin Film Nanomaterials

Completed
The behavior and performance of nanostructured materials and devices are governed by the chemistry and structure of their surfaces and interfaces. However, chemistry-structure-performance relationships in these systems are complex, so hundreds of experiments can be necessary to determine optimal

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

Macromolecule and Nanoparticle Composition and Architecture

Completed
Bringing new products to market requires measurements for rapid, quantitative assessment of composition and structure. To this end, NIST has developed a series of mass spectrometry-based tools that decrease the time necessary to achieve measurement success while producing more accurate results. The
complex oxides

Measurements of Point-Defect Chemistry in Complex Oxides

Ongoing
Project Goal: To develop magnetic resonance, x-ray absorption, electron diffraction, and electrical conductivity measurements to better characterize dilute concentrations of point defects in oxide materials and effectively correlate electro-mechanical properties to measured defect chemistry. Oxide

Metrologies for Non-linear Materials in Impact Mitigation

Ongoing
Overview This project develops fundamental structure-property measurements on model materials and novel material chemistries from quasi-static to dynamic rates. The goal is to foster a materials by design approach for novel energy dissipation and force re-direction mechanisms. Processing-Structure

Multifunctional 3D Printable Polymer-Metal Composites

Ongoing
Recent advances in additive manufacturing (AM) have positioned metals and polymers as two key materials. Typically, AM of these two materials involves incompatible methods and conditions. The novel multifunctional polymer-metal composites in this project incorporate low-melting alloys with

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

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

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

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
Composite Interphase

Polymer Composites

Ongoing
Measurements of interphase properties are extremely challenging, and their effects on macroscopic properties and performance of composites are poorly quantified. The objectives of this project fall into the following four research thrusts: Fluorescence Based Probes to Sense Damage and Water in
