Industrial facilities, manufacturing plants, and electric power plants that burn fossil fuels exhaust the combustion products to atmosphere through their smokestacks. Stack pollutant emissions are quantified using manual testing methods developed in the 1960s, which are prone to error if non-axial flow exists in a stack.Recently, NIST has been working on an improved technique of performing 3D flow ...

The cavity perturbation method is currently widely used for the characterization of the complex dielectric constant of material samples. This method provides a simple analytical solution by relating the real and imaginary parts of the dielectric constant of the sample to the changes in the measured resonant frequency and the quality factor of the loaded cavity. The validity of this method, howev ...

Businesses seeking to participate in NIST programs or to acquire technology from a federal laboratory are faced with a confusing myriad of starting points. Typically, time and money is expended to qualify the benefit of any program or technology. Even when the search is successfully concluded, it is common for the business or the federal contract to lack resources necessary to yield a commercial ...

Sweat contains biomarkers that give an indication of human cognitive levels. In this SBIR project TDA Research is developing a modular sweat sensor patch that has the capability to not only carry out real-time monitoring of select biomarkers, but also to

Many activities and technological systems prevalent in today’s society – air traffic control and air travel, the power grids, communications, deep-water drilling operations, human spaceflight – are vulnerable to the effects of sudden flares from our Sun. Because the propagation speed for flare emission is the speed of light, it is necessary to forecast these events in order to mitigate thei ...

nanoRETE is a developing a nanoparticle-based biosensor technology platform that has the ability for real-time detection of pathogens. Tuberculosis (TB) is a disease caused by Mycobacterium tuberculosis (Mtb) that primarily affects the lungs. In Phase I research, nanoRETE demonstrated proof-of-concept of an electrochemical nano-bead biosensor for measuring plasma cytokine and chemokine concentrati ...

To evaluate the technical feasibility of prompt gamma neutron activation (PGAA) as an alternative to a set of standard destructive tests of concrete petrography including aggregate type, water/cement ratio, aggregate/binder ratio, density, chloride content and chloride bulk diffusion constant; and to determine the specifications for the design of a dedicated commercial laboratory-based PGAA facili ...

This project will develop and demonstrate an inexpensive and portable calibration system for low-cost aerosol sensors. Current calibration methods are cost prohibitive and lack generalizability from one location (or season) to the next, making them impractical for implementation. Access Sensor Technologies (AST) proposes to improve and validate a solar powered aerosol reference calibrator (SPARC) ...

Veterans with amputations are relatively common as a result of war and peace keeping efforts. The civilian amputee population is also steadily growing as a result of vascular disease. For many years, there has been an emphasis on the development of prosth
