Measuring Form and Radius of Spheres With Interferometry

January 1, 2004
Author(s)
Quandou (. Wang, Johannes A. Soons, Ulf Griesmann
The geometry of a nearly spherical surface, for example that of a precision optic, is completely determined by the radius of curvature at one point and deviation from the perfect spherical form at all other points of the sphere. Measurements of radius and

Micro-Differential Scanning Calorimeter for Combustible Gas Sensing

January 1, 2004
Author(s)
Richard E. Cavicchi, G Poirier, N H. Tea, Muhammad Y. Afridi, David W. Berning, Allen R. Hefner Jr., John S. Suehle, Michael Gaitan, Stephen Semancik, Christopher B. Montgomery
A micron-scale differential scanning calorimeter (mDSC) has been produced on a silicon chip allowing for microscopic differential scanning calorimetry measurements on small samples. The device consists of a suspended rectangular microhotplate with sample

Microfluidic Analogue of the 4-Roll Mill

January 1, 2004
Author(s)
Steven D. Hudson, Frederick R. Phelan Jr., Matthew D. Handler, J Cabral, Kalman D. Migler, Eric J. Amis
Microfluidic technology promises to revolutionize analytical (bio)chemistry, because molecular separations are faster, less expensive and more efficient than in traditional large scale equipment. Materials and complex-fluid sciences can likewise benefit

Mobile 3D Visualization for Steel Structures

January 1, 2004
Author(s)
Robert R. Lipman
Until recently, visualization of 3D models required computational resources available only on desktop computers in office environments. With the advance of technology, it is now possible to visualize substantial 3D models on mobile handheld computers in

Modeling and Simulation for Emergency Response - Report of Workshop

January 1, 2004
Author(s)
Sanjay Jain, Charles R. McLean
A workshop on Modeling and Simulation for Emergency Response was held from March 4 to March 6, 2003 at NIST. The workshop program included talks and four breakout sessions that invited attendees to formulate recommendations in selected areas. The talks

Molecular Biomarkers Used to Detect Cellular/Genetic Damage in Tissue-Engineered Skin

January 1, 2004
Author(s)
C D. O'Connell, Peter E. Barker, M A. Marino, P McAndrew, Donald H. Atha, Pawel Jaruga, M Birincioglu, H Rodriguez
To assure that tissue engineered medical products are free of genetic changes that might occur from inflammation during the development phase of the product, Tissue engineered skin (TestSkin II) was obtained, separated into its two cellular layers
