Coherent Raman and Infrared Studies of Sulfur Trioxide

December 1, 2001
Author(s)
E T. Chrysostom, N Vulpanovici, Tony Masiello, J Barber, J W. Niblez, A Weber, A G. Maki, Thomas A. Blake
High resolution (0.001 cm -1) coherent anti-Stokes Raman scattering (CARS) was used to observe the Q-branch structure of the IR-inactive Ņ 1 symmetric stretching mode of 32S 160 3 and its various 18O isotopomers. The Ņ 1 spectrum of 32S 160 3 reveals two

Physical and Chemical Aspects of Fire Suppression in Extraterrestrial Environments

May 22, 2001
Author(s)
Fumiaki Takahashi, Gregory T. Linteris, Vishwanath R. Katta
A fire, whether in a spacecraft or in occupied spaces on extraterrestrial bases, can lead to mission termination or loss of life. While the fire-safety record of US space missions has been excellent, the advent of longer duration missions to Mars, the moon

Recent Advances in Flame Retardant Polymer Nanocomposites

Jeffrey W. Gilman, Takashi Kashiwagi, A B. Morgan, Richard H. Harris Jr., L D. Brassell, W H. Awad, Rick D. Davis, L Chyall, T E. Sutto, Paul C. Trulove, H DeLong
A new approach to address the ever increasing demand for higher performance flame retarded products has recently focused on use of mica-type clays nano-dispersed in commodity polymers. These "nanocomposites" exhibit the unusual combination of reduced

Statistics and Measurements

January 1, 2001
Author(s)
C M. Croarkin
For more than 50 years, the Statistical Engineering Division (SED) has been instrumental in the success of a broad spectrum of metrology projects at NBS/NIST. This paper highlights fundamental contributions of NBS/NIST statisticians to statistics and to

Supporting Relationships in Access Control Using Role Based Access Control

October 29, 1999
Author(s)
John Barkley, Konstantin Benznosov, Jinny Uppal
The Role Based Access Control (RBAC) model and mechanism have proven to be useful and effective. This is clear from the many RBAC implementations in commercial products. However, there are many common examples where access decisions must include other

Real-Time Control Systems for Robots

June 21, 1985
Author(s)
M L. Fitzgerald, Tony Barbera, James S. Albus
The advent of low cost microcomputer hardware has provided the capability for sophisticated control of robot machinery, allowing such features as straight line trajectory motions, sensory interaction, workstation integration, external database access and

H-Bonded Organic Frameworks as Ultrasound-Programmable Delivery Platform

February 5, 2025

Wenliang Wang, Yanshu Shi, Wenrui Chai, Kai Tang, Ilya Pyatnitskiy, Yi Xie, Xiangping Liu, Weilong He, Jinmo Jeong, Ju-Chun Hsieh, Anakaren Lozano, Brinkley Artman, Xi Shi, Nicole Hoefer, Binita Shrestha, Noah Stern, Wei Zhou, David McComb, Tyrone Porter, Graeme Henkelman, Banglin Chen, Huiliang Wang
The precise control of mechanochemical activation within deep tissues using non-invasive ultrasound holds profound implications for advancing our understanding of fundamental biomedical sciences and revolutionizing disease treatments1–4. However, a theory

Dual-comb correlation spectroscopy of thermal light

May 23, 2024
Author(s)
Eugene Tsao, Alexander Lind, Connor Fredrick, Ryan Cole, Peter Chang, Kristina Chang, Dahyeon Lee, Matthew Heyrich, Nazanin Hoghooghi, Franklyn Quinlan, Scott Diddams
The detection of light of thermal origin is the principal means by which humanity has learned about our world and the cosmos. In optical astronomy, in particular, direct detection of thermal photons and the resolution of their spectra have enabled

Threshold and Laser Conversion in Nanostructured-Resonator Parametric Oscillators

January 10, 2024
Author(s)
Haixin Liu, Grant Brodnik, Jizhao Zang, David Carlson, Jennifer Black, Scott Papp
We explore optical parametric oscillation (OPO) in nanophotonic resonators, enabling arbitrary, nonlinear phase matching and nearly lossless control of energy conversion. Such pristine OPO laser converters are determined by nonlinear light-matter

Quantum Plexcitonic Sensing

October 11, 2023
Author(s)
Peng Zheng, Stephen Semancik, Ishan Barman
Quantum sensing is poised to deliver unparalleled performance compared to its classical counterpart. While fundamental to quantum sensing, quantum state control has been traditionally limited to extreme conditions, such as a high vacuum or an ultra-stable

Calibration strategy of the PROSPECT-II detector with external and intrinsic sources
