Crystal Structure of Ba27Fe16Ti33O117

Author(s)
T Siegrist, Terrell A. Vanderah, C Svensson, Robert S. Roth
Single-crystal X-ray diffraction studies indicate that the compound Ba 27Fe 16Ti 33O 117- crystallizes in the rhombohedral space group R-3m, with a hexagonal

Polymer Composites with High Dielectric Constant

Author(s)
C. K. Chiang, R Popielarz
A very high dielectric constant polymer composite film system is presented. The new polymer composite film uses cyanoresin polymer filled with ferroelectric

Crystal Structure of the Compound Bi2Zn2/3Nb4/3O7

Author(s)
Igor Levin, T G. Amos, J Nino, Terrell A. Vanderah, I Reaney, C A. Randall, M T. Lanagan
The crystal structure of Bi2Zn2/3Nb4/3O7 was determined using a combination of electron, X-ray and neutron powder diffraction. The compound crystallizes with a

Brian R. Lawn, Y N. Deng, Isabel K. Lloyd, E D. Rekow, Victoria Thompson
Explicit fracture mechanics relations for the onset of critical damage in crown-like ceramic layers on soft polymeric substrates subjected to contacts loads are

Longitudinal Spin Waves in a Dilute Bose Gas

Author(s)
J E. Williams, T Nikuni, Charles W. Clark
We present a kinetic theory for a dilute noncondensed Bose gas of two-level atoms that predicts the transient spin segregation observed in a recent experiment
