timeline of neutron detector image spatial resolution

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
Neutron Imaging of Lithium and Alkaline Batteries

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
die-cast toy

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

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
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

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

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
