A schematic overview showing the distribution of the standardized samples to study participants, the use of standardized protocols for measurements, and standardized reporting of data back to NIST for analysis.

AAPS Interlaboratory Study: Protein Aggregation and Immunogenicity

Ongoing
To ensure the safety and efficacy of protein-based biotherapeutics, manufacturers strive to avoid unwanted immune responses caused by the biotherapeutic. Protein immunogenicity is a complex topic and depends on multiple factors related to the product, patient profile, and treatment. 1 , 2

Accelerated Weathering Laboratory: Metrology and Technology Transfer

Ongoing
Objective By 2027, validate and implement the NIST Accelerated Weathering Laboratory (AWL) technology for conducting accurate and traceable aging experiments. By 2028, transfer the SPHERE technology to industrial stakeholders. Technical Idea A NIST Accelerated Weathering Laboratory (AWL) has been

Additive Manufacturing Fatigue and Fracture

Ongoing
Metal additive manufacturing (AM) is not used in fatigue and fracture critical applications despite industrial need. The goal of this project is to enable confident use of metal AM in critical applications through: Advancing metrological practice for AM-specific performance metrics encompassing the

Advanced Cements and Concretes Consortium

Concrete, the predominant construction material, is used globally due to its properties such as strength, workability, elasticity, and durability and materials availability. To reduce costs, increase local sourcing, and ensure supply chain security, new strategies are being developed including the

Advanced Composites Pilot for the Materials Genome Initiative

Completed
Many computational programs exist that are being used by industry for predicting properties of polymer composites but their general predictive power is limited by how faithfully the microstructure is represented and how realistically the interfaces are handled. The computations are limited by the

Advanced Materials Metrology

Ongoing
Electromagnetic devices cannot operate without the interaction of electromagnetic waves with materials, and the characterization of the interface between fields and materials will be a critical task for any device or metrology development from nanoscale to larger scales. Areas of impact over the

Annual Machine Learning for Materials Research Bootcamp

Ongoing
Four days of lectures and hands-on exercises covering a range of data analysis topics from introduction to python and data pre-processing to advanced machine learning analysis techniques. Example topics include: Identifying important features in complex/high dimensional data Visualizing high
Aggregate Concrete

Assessing Pyrrhotite in Concrete

Ongoing
Objective Develop a standard test method and a set of calibration reference materials to quantify pyrrhotite in concrete; document pyrrhotite/aggregate/concrete reactions and rates so that the most deleterious reactions can be efficiently reduced or eliminated; and evaluate proposed mitigation

Atomistic Potentials and the Future of Nanomaterials Metrology

Ongoing
Atomistic simulations are increasingly being used as a tool to understand and predict properties of materials in systems, such as nanomaterials, where direct measurement is time-consuming or extremely difficult. The success of atomistic simulations depends critically on the fidelity of a specific

Automotive Lightweighting

Ongoing
The US auto industry spends $600M per year fixing and tweaking forming dies that do not make correct parts. The primary reason that the dies are inaccurate is that the computer models of the dies utilize materials models that are inaccurate. Upon surveying our industrial partners, we determined that
