Just How Perfect Can a Perfect Crystal Be?

Author(s)
R Deslattes, Ernest G. Kessler, S M. Owens, David R. Black, Albert Henins
This overview addresses certain aspects of the perfection of the current generation of commercially manufactured silicon, specifically lattice uniformity and...

Research on Combustion of Black-Liquor Drops

Author(s)
A Macek
Black liquor, the major by-product of the kraft process for production of pulp, is one of the most important industrial fuels. It is burned in recovery boilers...

Annealing Effects on the Coercivity of SmCo5 Nanoparticles

Author(s)
K Chowdary, A K. Giri, K Pellerin, S. A. Majetich, J H. Scott
The enhanced coercivity of ball milled nanoparticles of SmCo 5 has been attributed to the reduced particle size, but the milling process introduces additional...

Role of Oxygen Pressure during Deposition on the Microwave Properties of YBCO Films

Author(s)
David A. Rudman, F. J. Stork, James Booth, J. Y. Juang, Leila R. Vale, G. J. Beatty, C. I. Williams, James A. Beall, Ronald H. Ono, S. B. Qadri, M. S. Osofsky, E. F. Skelton, John H. Claassen, G. Gibson, J. L. MacManus-Driscoll, N. Malde, L. F. Cohen
We have studied the effect of oxygen pressure (PO 2) during pulsed laser deposition on the properties of YBCO films, with particular attention to the low power...

Long Term Stability of YBCO-Based Josephson Junctions

Author(s)
Leila R. Vale, Ronald H. Ono, J. Talvacchio, M. G. Forrester, B. D. Hunt, M. S. DiTorio, Ki Youl Yang, S. Yoshizumi
We report on a study of long term aging in three different types of Yba 2Cu 3O 7-x Josephson junctions. Junction aging will affect the choices made in...

Simultaneous Optimization of Linear and Nonlinear Microwave Response of YBCO Films

Author(s)
James Booth, James A. Beall, David A. Rudman, Leila R. Vale, Ronald H. Ono, Christopher L. Holloway, S. B. Qadri, M. S. Osofsky, E. F. Skelton, J. H. Claasen, G. Gibson, J. L. MacManus-Driscoll, N. Malde, L. F. Cohen
We present results of a systematic study of the effect of film deposition temperture on both the linear and nonlinear response of super-conducting Yba 2Cu 3O7-γ...

Superconducting Thin-Film Transformers at Microwave Frequencies

Author(s)
A. H. Miklich, J. X. Przybysz, T. J. Smith, Samuel Benz, Todd E. Harvey
We describe the use of thin-film superconducting transformers at frequencies up to 20 GHz. Transformers with turns ratios of 2,3, and 7 were fabricated out of...

Opening Up to Standardization

Author(s)
Barbara L. Goldstein, J. Cartwright
Today's electronics manufacturers are expected to reduce their time-to-market cycles and lower total costs simultaneously. Product development cycles and volume...

1 Volt DC Programmable Josephson Voltage Standard System

Author(s)
Charles J. Burroughs, Samuel Benz, Todd E. Harvey, Clark A. Hamilton
NIST has developed a programmable Josephson voltage standard (JVS) that produces intrinsically stable voltages that are programmable from -1.1 V to +1.1 V.
