Measurements and Standards to Support Nutrition Labeling

Ongoing
Well-characterized certified reference materials are needed by laboratories in the food testing and nutrition communities to facilitate compliance with labeling laws and improve the accuracy of information provided on product labels so that consumers can make good choices. As a result of the...

Measurements and Theory for Predicting Stem Cell Stability

Completed
Cell-based therapies require efficient manufacturing processes, as well as assurance of the safety and the stability of cellular products. However, our ability to predict the response of cells to environmental conditions is far from perfect. To move beyond empirical approaches, we are using...

Measures of Building Resilience and Structural Robustness Project

Ongoing
Objective: By FY2014, develop the measurement science to assess the disaster resilience of buildings through the use of risk-based assessment and decision methods, and develop performance-based pre-standards for mitigation of disproportionate collapse of steel and reinforced concrete structures...

Measuring Intermolecular Interactions with Electro-Acoustic Spectroscopy

Ongoing
We have a number of opportunities to collaborate with us. See below for details. What does this project aim to do for the chemical industry? Many industrial processes depend on the intermolecular environment- the solvents and ions that surround a molecule. These interactions impact separations...

Measuring Light-Matter Interactions in Chip-Based Optical Cavities

Ongoing
A "single emitter" is a structure that exhibits a transition from a high energy state to a low energy state, thereby generating a photon, or light emission. A variety of solid-state single emitters have been discovered or manufactured. One example is a quantum dot, a nanometer-scale structure that...

Measuring the Performance of Net-Zero Energy Homes

Completed
Objective: Develop the measurement science necessary to evaluate various technological approaches to achieve net-zero energy residential buildings, including innovative monitoring techniques, methods of test, performance metrics and high quality experimental data for the validation and improvement...

Measuring Security Risk in Enterprise Networks

Ongoing
For more information regarding the Measuring Security Risk in Enterprise Networks (formerly name: Techniques for Security Risk Analysis of Enterprise Networks), please visit the Computer Security Resource Center (CSRC).

Medical (Archive): Small-field Therapy Dosimetry Studies Using Alanine/EPR

Completed
Developments in radiotherapy have significantly increased the use of small fields in stereotactic procedures and IMRT fields composed of small fields. Ionization chambers are not always suitable where situations of high dose gradients, time-dose variance, and non-uniform beam distributions are...

Medical (Archive): Workshop for Radiobiology Dosimetry Standardization

Completed
Workshop Agenda with Presentations RADIATION DOSE IS MORE THAN A NUMBER! National Institute of Standards and Technology 100 Bureau Drive, Gaithersburg, MD Green Auditorium September 15 and 16, 2011 THURSDAY, SEPTEMBER 15, 2011 Welcome and Introduction Lisa Karam, NIST Bert Maidment, NIAID Norm...

Medical: Characterization of Dosimeters Used in Computed Tomography

Completed
The Dosimetry Group of the Radiation Physics Division has an on-going collaboration with the FDA, NIH, and the Walter Reed National Military Medical Center to characterize clinical dosimeters for the purpose of monitoring the radiation dose delivered to patients during computed tomography (CT) exams...
radionuclide calibrators

Medical: Standards for Clinical Radionuclide Calibrators

Ongoing
In nuclear medicine, clinical activity measurements are typically made using commercially available radionuclide calibrators (also referred to as “dose calibrators”) which incorporate a reentrant 4π ionization chamber and an electrometer. The current measured by these calibrators is translated into...
Schematic of approach to clean water membranes

Membranes for Clean Water

Completed
Impact Access to affordable, clean water is vital to the nation's economic growth and security. Polymer-based membrane separation technologies based on reverse osmosis, forward osmosis and nanofiltration will play an increasingly critical role in the production of clean, safe water. In order to...
rare earth ions in a host crystal

Memory

Ongoing
While photonic systems offer very robust qbits and are excellent for transporting quantum information between locations due to their minimal interactions with their environment, they are inconvenient for the storage of quantum information in one place. As a result there is significant interest in...

Metal Additive Manufacturing Laser Power Assessment

Ongoing
A calibrated (U=1.2 %, k=2) power meter was taken to a variety of AM locations (industry, academic, government, DoD) to anonymously assess the accuracy with which these institutions know the laser power being delivered to the workpiece. At each site, the LPBF operator was asked to use the AM system...
MANTA Logo

Method Assessment for Non-Targeted Analyses (MANTA) Program

Ongoing
Typical targeted analysis aims to detect and/or quantify a set of known chemical compounds using specific instrumental techniques (such as liquid chromatography with triple quadrupole mass spectrometry). In contrast, non-targeted analysis is an analytical technique that detects, identifies, and/or...
Absolute quantitation of mRNA molecules in bacterial cells

Methods for Absolute Quantitation of Transcription

Ongoing
The ability to engineer novel, useful functions into microbial cells for manufacturing or therapeutic applications has accelerated rapidly over the last few decades. However, the measurements required to underpin predictive engineering of these systems are typically not comparable across different...

Methods for Community Resilience Tradeoffs

Completed
Objective - To support community resilience planning in the context of multiple competing objectives, including sustainability, adaptation, and public health, by evaluating complementarities and tradeoffs. What is the technical idea? Communities face multiple competing objectives in planning...
