Sustainable Metals Processing and Alloy Development

Ongoing
Foundational measurement science is being developed to support sustainable innovations through alloy design and optimization. The integration of experiments and computational thermodynamics and kinetics tools with mechanistic models enables the prediction of key processing-structure-property...

Synchrotron X-ray Spectroscopic Imaging

Ongoing
Building off technologies and expertise developed in the Synchrotron X-ray Absorption Spectroscopy project, the Spectroscopic Imaging effort seeks to develop measurements that provide spatial mapping of the local chemical, electronic, and physical structure in advanced materials. Technology is...

Synthesis and longevity of candidate direct air capture (DAC) materials

Ongoing
We have been working on the identification and development of repeatable synthesis techniques for DAC materials for the purposes of generating repeatable samples for evaluating DAC characterization techniques. We have initially focused on impregnated and grafted aminosilane-silica materials. We are...

Teaching Liquid State Theory to an Artificial Neural Network (ANN)

Ongoing
Scientific questions: Can an ANN allow us to predict the structure of fluids that are impossible to predict numerically via liquid-state theory? Can we learn something about liquid-state theory itself by the nature of the trained ANN? What features do the hidden layers capture?...

Templated Assembly of Block Copolymer Films

Completed
Viable nanomanufacturing of templated block copolymers will require a capability to control orientation and line edge roughness of trillions of structures to within a single nanometer, however there are no existing platforms that meet this need. We are developing small angle x-ray and neutron...

Thermodynamic & Kinetic Data for Sustainable Energy

Completed
Knowledge of the thermodynamic, phase equilibria and diffusion properties of potential novel materials can greatly accelerate their development. However, the data needed for new, multi-component materials are often not available. The CALPHAD (Computer Coupling of Phase Diagrams and thermochemistry)...

Thermoelectric Measurements

Ongoing
Thermoelectric effects enable the inter-conversion of thermal and electrical energy, with applications that include solid-state waste heat recovery in engines for automotive and industrial manufacturing; power generation for aerospace, non-terrestrial exploration, and remote sensing; and...

Thin Film Electronics (Archived)

Completed
Today's electronics have reached a point where sheer computation power has yielded to 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...

Tissue Engineering

Ongoing
Tissue Engineering Measurands: Tissue engineering measurands are confusing to discuss and a charting method to improve communication is demonstrated. Measurement Assurance Strategies for Regenerative Medicine: Reliable methods for assessing product consistency and quality. Regenerative Medicine...

Training for Screeners and Lab Staff

Ongoing
Advances in primary screening technologies (x-ray, CT, AIT) have allowed the detection and discrimination of bulk quantities of potentially dangerous compounds on people or in bags. However, a secondary screening method - typically based on trace detection - is still required for correct...

Transport Property Measurements for Semiconductors and Energy Materials

Ongoing
The image above is an exploded cross section diagram representing the simplified structure layers in a MOSFET transistor. Thermoreflectance (TR) laser-based measurement techniques, a key focus of this project, can measure the thermal properties of substrates, thin films, multilayer structures, and...

Ultrafast Spectroscopy to Advance Microelectronics

Ongoing
Continued advancement in microelectronics, including analog and digital electronics, power electronics, optics and photonics, and micromechanics for memory, processing, sensing, and communications as defined by the OSTP “National Strategy on Microelectronics Research,” requires knowledge of material...

Using AI to Determine Structure-Property Relations in Materials

Ongoing
The Material Measurement Lab at NIST employs artificial intelligence for the prediction and discovery of materials characteristics. Our applications of artificial intelligence (AI) accelerate materials research as well as help the community learn about AI's capabilities and gain confidence in...

Validation of Density Functional Theory for Materials

Completed
A variety of systems will be considered in this work: Pure and alloy solids will be studied using periodic DFT methods with three distinct crystal structures that are relevant to the widely-used CALPHAD (Computer Coupling of Phase Diagrams and Thermochemistry) method. This study emphasizes the...

X-ray Testbed for Breakthrough Catalyst Measurements

Ongoing
Interested in collaborating? See below What does this project do for industry? Current measurement techniques are unable to follow the reaction pathways during catalysis and are limited to observing only the end products or looking at catalysts outside of realistic reaction conditions. Our new...
