Experimental Study of a Water Droplet Impinging on a Liquid Surface

January 1, 2002
Author(s)
Samuel L. Manzello, Jiann C. Yang
An experimental study is presented for water droplet impingement on a liquid surface. The impaction process was recorded using a high-speed digital camera at 1000 frames per second. The initial droplet diameter was fixed at 3.1 mm 0.1 mm and all

Fiber and Component Metrology for High-Speed Communications

January 1, 2002

Tracy S. Clement, Paul D. Hale, Paul A. Williams
Increased data rates require improved measurements. We give specific guidance to avoid measurement pitfalls in two critical high data rate areas: Polarization-mode dispersion and transmitter/receiver frequency response. For audiences familiar (not expert)

Field Test of a Photovoltaic Water Heater

January 1, 2002
Author(s)
Arthur H. Fanney, Brian P. Dougherty, J O. Richardson
A solar photovoltaic water heating system has been installed at the Great Smoky Mountains National Park. The system provides hot water for the restroom facilities at the Park's main visitor center. This paper gives an overview of the technology, describes

Fluoroalkyl Phosphorus Fire Extinguishing Agents

January 1, 2002
Author(s)
R E. Tapscott, J M. Shreeve, J D. Mather
Phosphorus compounds show extraordinary effectiveness as flame extinguishants, and there is evidence for a chemical mechanism. Most work to date, however, has emphasized alkyl phosphonates and related materials or phosphonitriles. The former compounds are

Formation of SEI on Cycled Lithium-Ion Battery Cathodes: Soft X-ray Absorption Study

January 1, 2002
Author(s)
Mahalingam Balasubramanian, H S. Lee, X Sun, Xiao-Qing Yang, A R. Moodenbaugh, James McBreen, Daniel A. Fischer, Ziwen Fu
The formation of a solid electrolyte interface (SEI) on LiNi 0.85Co 0.15O 2 cathodes from lithium-ion cells cycled at 40EC and 70EC was observed and characterized using soft x-ray absorption spectroscopy (XAS). XAS measurements were made in the energy

Fourier Transform Microwave Spectrum and Ab Initio Study of Dimethyl Methylphosphonate

January 1, 2002
Author(s)
R D. Suenram, Francis J. Lovas, David F. Plusquellic, A Lesarri, Y Kawashima, J O. Jensen, A C. Samuels
The rotational spectrum of dimethyl methylphophonate (DMMP) has been studied using a pulsed molecular beam Fourier transform microwave spectrometer. The spectrum is complicated by the internal rotation motions of the three methyl tops in the molecule as
