Saumil Samant, Monali Basutkar, Maninderjeet Singh, Ali Masud, Christopher A. Grabowski, Kim Kisslinger, Joseph Strzalka, Guangcui Yuan, Sushil K. Satija, Ikeoluwa Apata, Dharmaraj Raghavan, Michael Durstock, Alamgir Karim
Designing next generation light-weight pulsed power sources hinges on understanding the factors influencing the performance of high energy density storage materials. In prior work, we demonstrated the use of Cold Zone Annealing with Soft Shear (CZA-SS) as

Revised analysis of the fifth spectrum of rhenium (Re V)

February 17, 2017
Author(s)
Vladimir I. Azarov, R R. Gayasov
The spectrum of rhenium was observed in the (500 to 2100) A wavelength region. A 6.65 m normal incidence VUV spectrograph has been used to record the spectrum. The (5d3 + 5d26s) - 5d26p transition array of four times ionized rhenium, Re V, has been

In-Situ Soft X-Ray Studies of CO Oxidation on the Pt(111) Surface

August 1, 2004
Author(s)
D J. Burnett, A T. Capitano, A M. Gabelnick, A L. Marsh, Daniel A. Fischer, J L. Gland
Temperature programmed and isothermal fluorescence yield measurements have been used to characterize carbon monoxide oxidation on the Pt(111) surface for oxygen pressures from 0.027 Pa to 2.7 Pa over the 200 to 600 K temperature range. Carbon monoxide

Lucky Packets and Network Time Protocol (NTP)
