The Fingerprint Vendor Technology Evaluation (FpVTE) is an independently administered technology evaluation of fingerprint matching, identification, and verification system. It has been rebranded as FRIF TE E1N.

FiPy

Ongoing
The solution of coupled sets of PDEs is ubiquitous to the numerical simulation of science problems. Numerous PDE solvers exist, using a variety of languages and numerical approaches. Many are proprietary, expensive and difficult to customize. As a result, scientists spend considerable resources

Fire Debris and Explosives

Ongoing
Fire Debris Fire debris analysis involves the collection, analysis, and interpretation of data of debris collected from fire scenes. Samples are typically analyzed by gas chromatography mass spectrometry which results in a complicated chromatogram that must be interpreted. Projects in this area are

Fixed Point Development: Non-Metals

Ongoing
A fixed point is a reproducible reference temperature, usually either melting of freezing of a pure substance, that allows a standardized interpolation scheme for the purposes of temperature scale dissemination. Most SPRTs are long-stem designs that require immersion-type fixed points incorporating

Flammability Metrics for New Low-GWP Refrigerants

Completed
Objective: To develop the capability to measure and predict the burning velocity of mixtures of low-Global Warming Potential (GWP) refrigerants to allow the ranking of the mixtures in terms of their flammability, to assist in the selection and implementation of the best replacements for high-GWP

Fluctuations and Nanoscale Control (Archived)

Completed
In liquids, the motion of a nanoparticle results from a complex interplay of fluid flow, external and internal dynamics, and random Brownian motion. Each of these processes leads to fluctuations in a measured signal. Normally it is an important (and difficult) task for the experimenter is to

Fluctuations and Nanoscale Control Software (Archived)

Completed
For each file YYY.m, type "doc YYY" from the Matlab command prompt for documentation, literature references, and usage guidelines. DSigma2_Est.m Estimates the diffusion coefficient (D) and localization noise (σ 2 or "Sigma2") from single-particle tracking data. It implements the algorithms for the

Fluid Phase Nuclear Magnetic Resonance (NMR) Spectroscopy

Ongoing
In-situ vapor-liquid equilibrium (VLE). We are applying vapor-phase NMR to measure VLE in-situ . We are currently applying this methodology to industrially important systems such as refrigerants and natural gas. The most widely used refrigerants have high global warming potential. Drop-in

Fluid Suspensions and Emulsions

Ongoing
We aim to: Develop measurement capabilities to relate solution structure and viscosity through novel combinations of unique small volume, high shear rate rheometers with scattering and particle-imaging techniques. A major application of these capabilities is understanding self-association in fluids

Focused-ion-beam machining

Ongoing
Structure determines function in diverse nanotechnologies, so that making devices to control or measure nanoscale phenomena begins with control of nanoscale structure. Few fabrication systems outperform the focused ion beam to pattern nanostructures by directing ions of various elements to an
Food Nutrition Safety QAP

Food Nutrition and Safety Measurements Quality Assurance Program (FNSQAP)

Ongoing
As part of a revamp of QAPs in 2021, NIST established the FNSQAP to support the NIST Food Safety Program and Measurements and Standards to Support Nutrition Labeling. Participants measure nutrient components (e.g., minerals, vitamins, fatty acids, dietary fiber) and contaminants (e.g., toxic

Forensic Chemistry

Forensic Genetics

Ongoing
Since the late 1980s, NIST has had scientists involved in DNA testing (aka "DNA Fingerprinting"). Early concerns over measurement accuracy and poor quality control of forensic DNA tests caused the Department of Justice to call upon NIST scientists to help with standards development and technology

Forensic Handwriting Examination and Human Factors

Completed
For some 6,000 years, humans have made an indelible mark on history through the loops, strokes, and other characters that constitute the written form of language—handwriting. Whether it is the movement of a stylus inscribing wet clay or the motion of a pen across paper, handwriting is one of the
