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

Tattoo Recognition Technology

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?

Technical Security Guidance Program

Ongoing
This program can increase the security of computer systems, networks, and data. It will increase understanding of new security technologies and the security implications of new IT technologies. Specifically, the program can have the following impacts: - Eliminate duplication of efforts across

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

Completed
Viable nanomanufacturing of templated block copolymers will require a capability to control orientation and line edge roughness of trillions of structures to within a single nanometer, however there are no existing platforms that meet this need. We are developing small angle x-ray and neutron

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

Tension-Compression Testing

Ongoing
The inability to reliably predict the mechanical behavior of new automotive alloys during forming has generated strong demand for more advanced constitutive relationships and property data necessary to calibrate them. There is a particular need for models that incorporate combined kinematic and

Terahertz Imaging and Sources

Ongoing
Over the past several years, we have focused on bolometric detection of THz radiation. Our initial work on cryogenic detectors has been extended to antenna-coupled bolometers operating at room temperature. These detectors provide a rugged, low-cost alternative for homeland security applications; e.g

Theory of Spin-Orbit Torque

A ferromagnetic material such as iron acquires its magnetization because the magnetic orientation of its constituent atoms all line up in the same way. Because individual electrons also have an intrinsic magnetic moment – which is often referred to as the electron “spin” - they can interact with
