From a biomaterials perspective, three primary events can occur when a biodegradable polymer is implanted in vivo: 1) polymer degradation, 2) protein adsorption to the polymer and 3) swelling of the polymer as it absorbs water. These actions can affect the

Certification of SRM 46H

Chiara F. Ferraris, William F. Guthrie, Max A. Peltz, Robin K. Haupt
The standard reference material (SRM) for fineness of cement, SRM 114, is an integral part of the calibration material routinely used in the cement industry to qualify cements. Since 1934, NIST has provided SRM 114 for cement fineness testing and it will

Comparison of SEM and HRTEM CD Measurements Extracted from Test-Structures Having Feature Linewidths from 40 nm to 240 nm

Michael W. Cresswell, Richard A. Allen, William F. Guthrie, Christine E. Murabito, Ronald G. Dixson, Amy Hunt
CD (Critical Diminsion) measurements have been extracted from SEM (Scanning Electron Microscopy) and HRTEM (High Resolution Transmission Electron Microscopy) images of the same set of monocrystalline silicon features having linewidths between 40 nm and 240

Development of a thin film magnetic moment reference material

Robert R. Owings, Fabio C. Da Silva, David P. Pappas
This paper presents the results of an interlaboratory comparison and development of a magnetic moment reference material. The comparison was between the National Institute of Standards and Technology, magnetometer manufacturers, industrial, academic, and

Dynamic Force Measurement: Instrumented Charpy Impact Testing

January 1, 2008
Author(s)
Christopher N. McCowan, Jolene Splett, E. Lucon
The maximum forces measured by the machines in this round robin are in good agreement. This general result shows that the static force calibration of instrumented strikers is quite robust, and that the various striker designs evaluated here performed in a
