Optofluidic Cytometry

Ongoing
Flow cytometers are commercial instruments that provide rapid multiparameter measurements of single cells, which makes them indispensable in basic research and clinical studies of diseases and drug therapies. Measurements of cellular attributes can include indicators of cell size and shape and well

Optomechanical Pressure Sensing

Ongoing
Measurement and control of high-vacuum pressure is important for many industrial processes, particularly semiconductor fabrication. Typical process pressure monitors are known to lose accuracy over time and so require repetitive calibration. Pressure transfer standards that support high-vacuum and

Organic Compounds in Human Serum, Milk, and Urine

Ongoing
Standard Reference Materials (SRMs) have been specifically designed to assist in the quality assurance measurements for compounds found in human fluids. Clinical and biomonitoring laboratories rely on these SRMs for method validation and as control materials during specific analyses. Various human

Orthogonal Measurements

Ongoing
Definitions: Orthogonal measurements: Measurements that use different physical principles to measure the same property of the same sample with the goal of minimizing method-specific biases and interferences. Complementary measurements: Measurements that corroborate each other to support the same

Other activities to support government organizations

Ongoing
Recent projects include: Developing uncertainty analyses for an outdoor near-field antenna test rangeWe are analyzing near-field scanning data from the U.S. Army’s Electronic Proving Grounds (EPG) and will then provide technical support to the Army for any necessary corrections to the range’s

Out-of-Band Emissions Measurements of LTE Devices Operating in the AWS-3 Band

Completed
The project, proposed by Edwards Air Force Base, measured Out-of-Band (OoB) emissions from new Long Term Evolution (LTE) systems operating in bands adjacent to existing incumbent Department of Defense (DoD) Aeronautical Mobile Telemetry (AMT) systems used at government test and training ranges (TTRs

OWM Training Program: Metrology, Metrication, and More!

Ongoing
OWM offers a variety of in-person, online, and "blended" training classes and materials that provide guidance instruction on national legal metrology standards, weights and measures field inspection procedures, and laws and regulations related to packaging and labeling. OWM provides technical

Pacific Marine Mammal Health Assessments (PMMHA)

Completed
Pacific Marine Mammal Health Assessments (PMMHA), which began in Fall 2010, are an expansion of NIST marine mammal health assessment collaborations that began in 2002 with bottlenose dolphin wild populations. NIST has a history of involvement in marine mammal health assessment related work

The Parallel Hierarchical Adaptive MultiLevel Project (PHAML)

Ongoing
The main accomplishments and features of PHAML are: low and high order finite elements on triangle grids a novel approach to parallel data distribution (the Full Domain Partition) h-, p-, and hp-adaptive mesh refinement based on newest node bisection multiple choices for a posteriori error

Particles, Tubes, and Colloids

Ongoing
Description A highlight of the PTC project is our success in purification of well-defined SWCNT populations using liquid phase separation methods. Although we use multiple techniques and methods, ion exchange chromatography, rate-zonal and isopycnic ultracentrifugation, size exclusion chromatography

Pathogen Detection and Identification: The Next Generation of Analyses

Ongoing
Human disease resulting from pathogens represents a tremendous burden on the health care system. Many hospitals have adopted new, rapid polymerase chain reaction (PCR)-based detection systems because the time to diagnose and begin effective treatment has a direct impact on patient survival and

Peptide Mass Spectral Libraries

Ongoing
Intended Impact Modern mass spectrometers used in the field of proteomics are capable of profiling thousands of peptides in a single experiment. Each of these peptides is fragmented to form a mass spectrum. Therefore, interpretation of these mass spectra is a critical step in the experimental

Per- and Polyfluoroalkyl Substances (PFAS)

Ongoing
Perfluorinated and polyfluorinated alkyl substances (PFAS) constitute a family of compounds that are distinguished by partial or complete fluorination of alkyl hydrocarbons. Dubbed “forever chemicals”, the unique chemistry of PFAS imparts a high level of stability, making the compounds resistant to

Perception Performance of Robotic Systems

Ongoing
Objective To develop measurement science for characterizing sensing and perception system performance to reduce the risks of adopting these technologies and to advance the agility, safety, and productivity of collaborative, industrial, and mobile robots. Technical Idea Over the past 5 years, the

Performance Assessment Framework for Robotic Systems

Completed
Objective: Enable manufacturers to assess and assure robot system assembly task performance by delivering a methodology and tools for characterizing and composing performance of perception, mobility, dexterity, and safety components. Technical Idea: The new technical idea is to compose assembly task

Performance of Collaborative Robot Systems

Ongoing
Objective: Deliver a suite of test methods, protocols, and information models to assess and assure that robots working collaboratively in human-robot and robot-robot teams will complete their assigned tasks safely and correctly while meeting their assembly performance objectives. Technical Idea: To

Performance Criteria Development

Ongoing
Objective To advance component-level seismic performance criteria in current design standards by conducting focused experimental tests and analytical studies. Technical Idea In the following, the technical idea for each of the RTs is presented separately: RT1: High-Strength Reinforcement in

Performance of Emergency Response Robots

Ongoing
Objective To develop the measurement science necessary to quantitatively evaluate the capabilities of autonomous and remotely operated robotic systems along with the proficiency of remote operators and pilots for emergency response applications. Technical Idea Emergency responder missions can be

Performance of Emerging Technologies for Robotics

Ongoing
Objective To identify opportunities for and barriers to greater adoption of robotics by small manufacturers, and to establish the metrology bases needed for assessing, accepting, and advancing novel technologies that meet the current and emerging needs of small- and medium-sized manufacturers

Performance of Human-Robot Interaction

Ongoing
Objective To deliver a suite of datasets, benchmarking tools, test methods, protocols, metrics, standards, and information models to enable effective, human-robot collaboration in manufacturing, and advance interactive robot technologies to facilitate the safe and efficient teaming of people and

Performance Metrics for Industrial Gas Separation and Purification

Ongoing
Sorbents in Direct Air Capture (DAC) are exposed to the atmosphere, where they adsorb CO2 then are isolated from atmosphere, the CO2 is driven off by heating or pulling vacuum, refreshing the sorbents. This adsorption-refresh cycle depends not only on the competitive adsorption of CO2 with the other

Performance Metrics for Proteomics

Ongoing
Intended Impact Proteomics experiments designed to identify protein markers specific to a particular disease or disease state rely on repeatable identification of proteins within a control set. Repeatability provides statistical assurance that clear differences between two sets (e.g. sick vs
