Multi-Sample Couette Viscometer for Polymer Formulations

January 1, 2005
Author(s)
H J. Walls, Robert F. Berg, Eric J. Amis
We describe a prototype scalable viscometer aimed at facilitating rapid measurements of multiple samples. The device simultaneously measures the viscosity of four samples in an array of Couette cells. Each cell contains a rotor with an embedded permanent

New Capabilities At NIST In Dimensional Metrology

January 1, 2005
Author(s)
Theodore D. Doiron, Eric S. Stanfield, Bryon S. Faust, John R. Stoup, Mary Abbott
A number of new or revised services in dimensional metrology are presented. Included are: a lower cost, high accuracy calibration for sphere diameter; reduced uncertainty in roundness calibration; a new instrument for measurement of the thermal expansion

New Magnetic Phases of bcc-Co Thin Films

January 1, 2005
Author(s)
T Monchesky, John Unguris
We have been able to observe two new magnetic phases of ultrathin Co by growing atomically well ordered Co films on cleaved GaAs(110) substrates. For a Co thickness less than 3.4 monolayers (ML), we find a ferromagnetically dead layer associated with the
