Imaging: Evolution of Neutron Image Detector Spatial Resolution

Completed

Neutron imaging has yielded valuable insight into the water content of fuel cells because minimal changes to a test section are needed. A limit of neutron imaging is the achievable spatial resolution, which is primarily dominated by the detector. Figure 1 shows the evolution of the spatial...

Imaging: Improving Lead Battery Efficiency with Neutron Imaging

Completed

Scientists will be joining forces with NIST from INMA (Instituto de Nanociencia y Materiales de Aragón) and Exide Technologies, a global battery company through one of its R&D centers based near Madrid. They will study the fundamental processes that govern recharge efficiency and battery electrode...

Imaging: M2FCT - The Million-Mile Fuel Cell Truck Consortium

Ongoing

True in operando imaging of PEMFCs to observe and quantify water transport phenomena is only possible with neutrons. NIST, in partnership with General Motors and support of the EERE has developed a world-class facility for in operando neutron imaging of fuel cells for light duty vehicles. Upgrades...

Imaging: Neutron Imaging for Advanced Catalyst Development and Durability Studies

Completed

Two of the most critical challenges to commercialization of PEMFCs for automotive applications are the cost of the Pt used in the catalyst layers and the system lifetime. Because the oxygen reduction reaction in the PEMFCs is slow and at low temperatures, finding a suitable replacement for Pt has...

Imaging: Neutron Imaging of Lithium and Alkaline Batteries

Completed

This is due to the high sensitivity of neutrons to hydrogen, while having relatively small sensitivity to many common materials of construction such as aluminum and carbon. Neutron imaging can play a similar role in advanced battery development by providing in situ measurements of hydrogen or...

Imaging: Neutron Tomography of Hydrogen Storage Bed

Completed

While many techniques exist to measure the volume average of the hydrogen uptake, to date no method exists that can measure the full three-dimensional hydrogen distribution within the storage vessel. In order to address this shortcoming, a prototype hydrogen storage bed has been studied using...

Imaging: The Neutron and X-ray Tomography (NeXT) System

Ongoing

Neutrons and X-rays are complementary, nondestructive, penetrating probes of matter. X-rays interact with the electron cloud of atoms and therefore sees increasing attenuation with atomic number while neutrons interact with the nuclei resulting in a very scattered pattern with atomic number. The...

Imaging: Toward a Neutron Microscope

Ongoing

The NIST Neutron Microscope The NIST neutron microscope based Wolter optics represents a complete change in the way neutron imaging will be conducted, as the time and spatial resolution achievable with this instrument will approach that early generation X-ray synchrotron beamlines. A collaboration...

Imaging: Using Neutron Imaging to Advance Low Temperature Hydrogen Electrolysis

Ongoing

PEM Electrolyzers are similar in design to PEM Fuel Cells, which allows for similar imaging methods to be employed. As described elsewhere for fuel cells (HYPERLINKS) neutron imaging is an established method to study transport phenomena in PEM electrochemical cells in situ. Neutrons are able to...

Impact of LTE Signals on GPS Receivers

Completed

To better understand the potential impact of adjacent-band LTE signals on GPS receiver performance, NASCTN developed a draft test plan designed to measure how the performance of GPS receivers changed as a function of increasing LTE signal power relative to a baseline with no LTE emissions. NASCTN...

Impact of Material Composition on Ignitability and Fire Growth

Ongoing

Volume 1 Experimental Observations of the Burning Behavior of Combustible Solids in Parallel Panel Configuration at Full-Scale ( NIST Technical Note 2282 ) Report Summary This report provides an overview of measurements (e.g., heat release rate, gaseous species production, and flame-to-surface heat...

A network of 629 papers co-authored by chemist A.W. Castleman.

Impact Metrics

Ongoing

In response to h-index requests from NIST management and staff, Library staff provide comprehensive publication analysis studies and reports that ensure the h-index is put in proper context as one of several ways to assess the impact of an individual or group. The Library can also compile non...

Improved Assessment Criteria for Performance-Based Seismic Design

Completed

Objective - Task (1): To establish a new generation of performance-based design assessment criteria that captures a component action’s dependence on loading history by conducting a set of focused experimental tests and computer simulations on eccentrically braced frame link beams. Task (2): To vet...

Improved Benchtop Connectivity to Complex Microfluidic Devices

Completed

Intended impact Microfluidic devices with many fluidic and pneumatic inlets are difficult to connect to benchtop reservoirs and controllers. Many hours can be spent sorting, untangling, and connecting tubing to a single device. If one then finds that the device is not fully functional, the process...

Figure with five interlocking puzzle pieces representing different aspects of the measurement process.

Improving High-Performance Inductively-Coupled Plasma Optical Emission Spectrometry (HP-ICP-OES) Through Exact Matching

Ongoing

A thorough understanding of the analytical benefits and characteristics of the implementation of exact matching with HP-ICP-OES will enable HP-ICP-OES to be applied more effectively to a variety of NIST measurements. Such measurements include, but are not limited to, value assignment measurements...

Improving WUI Community Fire Protection- Fire Resistant Building Design and Materials

Completed

This project develops fire-resistant building components, community construction designs, and advanced materials to resist ignition and limit the spread of wildland-urban interface fires.

IMS Visualization

Ongoing

To provide visualization tools for use by the IMS project and other network researchers to support development of fundamental metrics. NIST has a high level of visualization expertise and the vast amount of data being produced by the Fundamental Measures (IMS) project requires these types of...

$Minimum Deviation Refractometer System$

Index Properties of Optical Materials (0.12 μm – 15 μm)

Ongoing

The real part of the refractive index, its wavelength dispersion, and its temperature dependence are the key parameters for the design of refractive optical elements for optical systems. The demands for continually improved precision of optical instruments has driven a need for increasingly accurate...
