Evaluation of Dental Adhesion and Durability by Means of the Microbond Test

February 25, 1998
Author(s)
Joseph M. Antonucci, Walter G. McDonough, Joy P. Dunkers
The phenomenon of interfacial of interphase adhesion is a critical factor in determining the strength and durability of multiphase dental materials. For example, the clinical performance of acrylic polymer based dental composites depends to a large extent

Sprinklers, Vent, and Draft Curtain Interaction: Modeling and Experiment

February 25, 1998
Author(s)
Kevin B. McGrattan, Anthony P. Hamins, D. D. Evans
The second and most recent application of the NIST Industrial Fire Simulation (IFS) System is to predict the performance of sprinklers, draft curtains and roof vents in storage facilities and retail spaces. The IFS System is a series of computational fluid

The Influence of the matrix Modulus on the interfacial Shear Strength Parameter

February 25, 1998
Author(s)
Gale A. Holmes, R C. Peterson, Donald L. Hunston, Walter G. McDonough
In composite structures, adhesion at the fiber-matrix interface is typically determined indirectly from experimental data and theoretical models. These models make varying assumptions about the fiber, matrix, and fragmentation process. Therefore, the

Using Sensor Data to Predict the Environment in a Building

February 25, 1998
Author(s)
Walter W. Jones, Richard D. Peacock, Glenn P. Forney, Paul A. Reneke
As transducers become more commonplace in the built environment, it is desirable to utilize this information in a more complete way to assure safety. There are two fi to doing this, incorporating our knowledge of fires and other extreme events into the

Crystal Structure and Properties of Ba 5 Fe 4 ^Ti 10 O 31

February 23, 1998
Author(s)
T Siegrist, Terrell A. Vanderah, A P. Ramirez, Richard G. Geyer, Robert S. Roth
Using single-crystal and powder X-ray diffraction methods, the crystal structure of the new compound Ba 5Fe 4Ti 10O 31 was determined and its magnetic and dielectric properties were measured. Ba 5Fe 4Ti 10O 31 crystallizes in space group P6 3/mcm (no. 193)

Anisotropic Microstructure Development During the Reaction of Mg With GaAs

February 18, 1998
Author(s)
Steven W. Robey
Reaction of Mg with GaAs (001) surface occurs at substrate temperatures above 250 K and leads to 3D growth of an epitaxial, cubic reaction phase with a lattice constant of 0.62 + 0.02nm, 9% larger than GaAs. The resulting anistotropic, 3-demiensional (3D)
