Scatterfield Optical Imaging for sub-10 nm Dimensional Metrology

January 1, 2009
Author(s)
Richard M. Silver
Recent developments in optical microscopy promise to advance optical metrology and imaging to unprecedented levels through theoretical and experimental development of a new measurement technique called "scatterfield optical imaging". ". Current metrology

SIM Comparison of DC Resistance Standards at 1 {O}, 1 M{O}, and 1 G{O}

January 1, 2009
Author(s)
Dean G. Jarrett, Randolph E. Elmquist, Nien F. Zhang, Alejandra Tonina, M Porfiri, Janice Fernandes, H Schechter, Daniel Izquierdo, C Faverio, Daniel Slomovitz, Dave Inglis, Kai Wendler, Felipe Hernandez-Marquez, B Rodriguez
A set of regional comparisons of dc resistance standards at the nominal values of 1 {Ω}, 1 M {Ω}, and 1 G {Ω} has recently been completed in the Sistema Interamericano de Metrogia (SIM) region. The motivation, design, standards, and results of these

Stairwell Evacuation from Buildings: What We Know We Don't Know

January 1, 2009
Author(s)
Richard D. Peacock, Jason D. Averill, Erica D. Kuligowski
Occupant descent down stairwells during building evacuations is typically described by measurable engineering variables such as stairwell geometry, speed, density, and pre-evacuation delay. In turn, predictive models of building evacuation use these

Stray Light Correction of the Marine Optical System

January 1, 2009
Author(s)
M Feinholz, S Flora, M Yarbrough, Keith R. Lykke, Steven W. Brown, B. Carol Johnson, Dennis Clark
The Marine Optical System is a spectrograph-based sensor used in the Marine Optical Buoy for the vicarious calibration of ocean color satellite sensors. It is also deployed from ships in instruments used to develop bio-optical algorithms that relate the

Surface Engineering of Styrene/PEGylated-Fluoroalkyl Styrene Block Copolymer Thin Films

January 1, 2009
Author(s)
Elisa Martinelli, Sara Menghetti, Giancarlo Galli, Antonella Glisenti, Sitaraman Krishnan, Marvin Y. Paik, Christopher K. Ober, Detlet-M Smilgies, Daniel A. Fischer
A series of diblock copolymers prepared from styrenic monomers was synthesized using ATRP. One block was derived from styrene while the second block was prepared from a styrene modified with an amphiphilic PEGylated-fluoroalkyl side chain. The surface
