Tandem Mass Spectral Library

Ongoing
Intended Impact Modern mass spectrometers commonly generate ions by electrospray mass spectrometry which are separated and then fragmented by collisional dissociation. This process yields fragment ion ‘fingerprints’ (or mass spectra) that are widely used to identify the individual components in a

Targeting Membrane Proteins

Ongoing
Membrane proteins constitute approximately 30% of all cellular proteins. Nevertheless, this group of proteins is traditionally understudied due to limitations of the available analytical tools. Given the importance of membrane proteins in the various cellular processes and their potential as drug

Teaching Liquid State Theory to an Artificial Neural Network (ANN)

Ongoing
Scientific questions: Can an ANN allow us to predict the structure of fluids that are impossible to predict numerically via liquid-state theory? Can we learn something about liquid-state theory itself by the nature of the trained ANN? What features do the hidden layers capture?

Technological Advances in Aquaculture

Ongoing
According to the NOAA Fisheries of the U.S. report, in 2020 U.S. seafood consumption was estimated at ~6B pounds (~2.7 x 109 kg). Of that, 85% is imported and U.S. exports have seen a significant decline. Globally, the U.S. ranked only 18th in aquaculture production (2020). NIST aims to enhance the

Temperature Sensitivity of Liquid Flow Meters

Completed
The Fluid Metrology Group is using NIST’s 15 kg/s water flow standard (Fig. 1) to test how coriolis meters are affected by liquid and environment temperatures. The water flow standard is a closed-loop, dynamic liquid flow calibration facility that is fully automated. For this work, calibrations were

Templated Assembly of Block Copolymer Films

Temporal Computing

Ongoing
In standard integrated circuits, information that is coded as ones and zeros is implemented by voltages on wires being high or low. The circuits consume energy during transitions between these voltages. Binary numbers have a voltage per bit so there are a lot of transitions each time a number
