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

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 Mass Spectrometry Methods for Trace Detection

Ongoing
Ambient Ionization Mass Spectrometry (AI-MS) AI-MS remains a versatile field enabling direct analysis of samples in situ, requiring minimal or no sample preparation. These platforms are leveraged for the trace detection of organic and inorganic compounds, including, homemade and improvised

Advanced Mechanical Characterization of Mesoscale Materials

Ongoing
Knowledge of a material’s mechanical properties is key to designing safe and reliable structural components for applications ranging in size from medical implants to large civil engineering structures. Traditionally, a material’s mechanical properties are measured by performing mechanical tests on

Advanced Microscopy for Trace and Bulk Particle Characterization

Ongoing
The goal of this project is to help develop innovative metrologies and measurement protocols for micro/nano-scale analysis of particles. In this project, state-of-the-art optical and electron-based microscopy are used to conduct research for quantitative and qualitative analysis of chemical

Ambient and Atmospheric Pressure Mass Spectrometry

Ongoing
Surface and Trace Chemical Analysis Group employs a range of commercial pneumatically-assisted electrospray ionization (ESI), atmospheric pressure chemical ionization (APCI), and atmospheric pressure photoionization (APPI) sources for traditional mass spectrometric chemical analysis, identification

Analysis of Copper Incorporation Into Zinc Oxide Nanowires

The lasing capabilities and piezoelectric properties of single ZnO nanowires offer promise for future technologies. However, the photoluminescence of ZnO nanowires differs depending upon the synthesis method and the defects present in the sample. This project was undertaken to characterize zinc

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

Autonomous Scanning Droplet Cell

Ongoing
Corrosion impacts a broad spectrum of application areas including infrastructure, transportation, and the military. The annual price tag for corrosion mitigation and remediation is 3.4 % of the US GDP. The team is particularly interested in discovering new metallic glasses (metals without long range

Biofabrication of Tissue Engineered Constructs

Ongoing
OCT imaging was assessed using a model scaffold-cell system consisting of a polysaccharide-based hydrogel seeded with human Jurkat cells. Four test systems were used: hydrogel seeded with live cells, hydrogel seeded with heat-shocked or fixed dead cells and hydrogel without any cells. Time series

Broadband Coherent Anti-Stokes Raman Scattering (BCARS) Microscopy

Ongoing
Impact There is a need for label-free chemical microscopy in medicine, biology and materials science. Most of the current methods use chemical labels that often disturb the distribution and nature of chemical components being investigated. The method we are developing enables noninvasive and rapid

Carbon Removal, Capture, Use, and Sequestration

Ongoing
NIST develops benchmark materials, measurements, data, and models to accelerate innovation in and validate performance of materials and technologies for the capture of carbon from air and sequestration in building materials.

A Comparison of WD-EPMA Heterogeneity Testing Procedures

Ongoing
X-ray stage mapping (XSM) can be used to determine the extent of heterogeneity on the micron scale though it is more time consuming and not as accurate as the more rigorous NIST random-point (RP) testing procedure. The objective of this work is to demonstrate the advantage of the latter procedure

Crystallographic Databases

Ongoing
Impact and Customers Materials with new or improved properties are continually being developed to meet demands for increased functionality of components and devices at decreased costs. Examples of multi-million dollar industries driven by materials advances are solid-state lighting (GaN-based

Electronic Material Characterization

Ongoing
Manufacturing optimized devices that incorporate newly-emerging materials requires predictable performance throughout device lifetimes. Unexpected degradation in device performance, sometimes leading to failure, is often traceable to poor material reliability. Reliability is rooted in the stability

Femtosecond Nonlinear Optical Spectroscopy of Nanoscale Materials

Ongoing
The purpose of this project is to develop and refine spectroscopic techniques based on nonlinear optics for the study of novel materials. Measurements that isolate the nonlinear response are often better able to uncover physical processes that, in the linear response, are subtle and hard to isolate

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
