NCNR DAC and CCUS efforts

Ongoing
Objectives To advance US competitiveness in Direct Air Capture (DAC) and Carbon Capture, Usage, and Sequestration (CCUS) Use advanced neutron scattering techniques to understand the adsorption process for the most promising materials for adsorption-based carbon capture and provide avenues to

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

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
Schematic of selective transport of water, ions, or molecules across a polymer membrane.

Polymer Membranes

Ongoing
We are developing and applying the following advanced tools to measure the structure, dynamics, and performance of polymer-based membranes and sorbents: Vibrational Spectroscopy We have developed a custom-built tandem quartz crystal microbalance (QCM), which measures total mass uptake of adsorbed

Pushing the Limits of Measurement Accuracy in Atom Probe Mass Spectrometry

Ongoing
Isotopic Analysis for Isotopic Geochemistry, Nuclear Safety, and Materials Science : Atom probe tomography has a significant advantage over other forms of mass spectrometry, which typically have a combined efficiency < 5%, in terms of ionization and detection efficiency. Commercial atom probe

Stroboscopic TEM for Ultrafast Materials Science

Ongoing
Our people: June Lau co-invented the stroboscopic microscope and had been with this project since inception. She is a physicist, and the PI of this project. She received 2 non-provisional patents for the design of the microscope, and one provisional patent on a specimen holder for microwave delivery

Structural Metrology of Advanced Manufacturing Processes

Ongoing
Understanding material structures in advanced manufacturing is crucial because it enables precise control over material properties, leading to improved performance, efficiency, and cost-effectiveness in production processes. However, this understanding poses many challenges, such as the

Study of Microheterogeneity in Solid Reference Materials

Ongoing
Presently there are a variety of analytical techniques that are served by few or no reference materials due to the small sample sizes they require. NIST currently certifies solid reference materials at or above the 100 mg mass level in most cases with no mention of the effect of using smaller sample

Sub-nanoscale electron microscopy of complex nanostructures

Ongoing
The properties of advance materials are becoming ever more reliant on the ability to manipulate their chemistry and structure at very fine length scales. For example, the relevant feature sizes in state-of-the-art transistors continue to decrease, even as the complexity of the architectures employed

Synchrotron X-ray Absorbance Spectroscopy

Ongoing
The Absorbance Spectroscopy effort seeks to develop measurements that provide details of the local chemical, electronic, and physical structure in advanced materials. Spectrometer technology is developed as part of the NIST BNL partnership at the National Synchrotron Light Source II in Upton, NY
SRM 3452 certified Seebeck coefficient data

Transport Property Measurements for Semiconductors and Energy Materials

Ongoing
The properties of materials and interfaces that govern reliability, performance, and thermal transport in advanced microelectronic packages are not fully characterized or understood, especially at device length scales wherein properties may differ significantly from bulk or literature values
Catalyst Testbed

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
