Simultaneous Measurement of Torque, Axial Force and Volume Change in the Torsional Dilatometer and the Implications for Constitutive Modeling

January 1, 1999

Author(s)

Carl R. Schultesiz, G B. McKenna

The NIST Torsional Dilatometer measures simultaneously the torque, axial normal force and volume change in response to a torsional deformation. In stress-relaxation experiments with an epoxy cylinder near its glass transition, the torque and normal force

Solid State Gas Microsensors for Environmental and Industrial Monitoring

January 1, 1999

Author(s)

R M. Walton, Richard E. Cavicchi, Stephen Semancik, B Panchapakesan, Don L. DeVoe, M I. Aquino-Class, J D. Allen, John S. Suehle

We describe solid state gas microsensor array technology for real-time, low-cost environmental and industrial monitoring. The four-element, surface-micromachined arrays are designed in CMOS technology and consist of multiple platforms called microhotplates

Sources of Error in Absolute Distance Interferometry

January 1, 1999

Author(s)

Jack A. Stone Jr., Alois Stejskal, Lowell P. Howard

In this paper we describe the status of our research on the use of diode lasers for absolute distance interferometry, and we discuss the major sources of uncertainty that limit the accuracy of this technique for distance measurement. We have primarily

Spatial Correlations of Mobility and Immobility in a Glassforming Lennard-Jones Liquid

January 1, 1999

Author(s)

C Donati, S C. Glotzer, P H. Poole, W Kob, S J. Plimpton

Using extensive molecular dynamics of an equilibrium, glass-forming Lennard-Jones mixture, we characterize in detail the local atomic motions. We show that spatial correlations exist among particles undergoing extremely large (mobile) or extremely small

Spectral Irradiance Calibration in the Infrared. XI. Comparison of a Bootis and 1 Ceres with a Laboratory Standard

Spin-on-Glass Thin Films Prepared From a Novel Polysilsesquioxane by Thermal and Ultraviolet-Irradiation Methods

January 1, 1999

Author(s)

Q Pan, G B. Gonzalez, R J. Composto, William E. Wallace, B Arkles, L K. Figge, D H. Berry

The pyrolytic and photolytic conversion of a new polymer precursor, namely -chloroethyl-silsesquioxane (BCESSQ), to an ormosil film is presented. At 350 C the film thickness rapidly decays to 55% of its original thickness within 60 min. A range of ion
