The physics package for a chip-scale atomic frequency reference was constructed and tested. The device has a total volume of 9.5 mm 3, dissipates 75 mW of
We have implemented a quantum key distribution (QKD) system with polarization encoding at 850 nm over 1 km of optical fiber. The high-speed management of the

Numerous chemical analyses of gaseous and particulate samples from laboratory flames provide a library of data on the polycyclic aromatic hydrocarbons (PAH)
An embedded system is a hybrid of hardware and softwarethat combines software flexibility and hardware real-time performance. The co-design of hardware and

Phase equilibrium studies of the title systems all reveal the formation of non-stoichiometric, displacively disordered pyrochlore phases. Formation of other
In this study, multilayered PbTixZr1-xO3 (PZT) samples (produced at sintering temperatures in the range of 1175 degrees C ¿ 1325 degrees C) were electrically

Carbon nanotubes are revolutionary materials, with properties that are vastly different than any other bulk form of carbon. Their unique combination of
Silicon-based ceramics such as silicon nitride can be very effectively lubricated by water under certain conditions (1-3). After a wear-in period a condition of
Measurement of complex hydrocarbon film thickness on engineering surfaces such as magnetic hard disks is difficult if the film thickness is below the peak to
Nearly all of the radiometric standards for laser power and energy measurements at NIST and elsewhere in the world are based on thermal detectors. These
The absolute responsivity of a thermal detector depends on its absorption efficiency as a function of wavelength. We present experiments and document the

Firebrands or embers are produced as trees and structures burn in wildland/urban interface (WUI) fires. Hot firebrands ultimately come to rest and may ignite
Quantifying the ventilation available to a room fire is an important step to understanding fire behavior. The fresh air that moves into an enclosure provides
