Surfaces, Interfaces, and Changing Shapes

October 16, 2008
Author(s)
Daniel Josell, F Spaepen
It is generally recognized that the capillary forces associated with internal and external interfaces affect both the shapes of liquid-vapor surfaces and wetting of a solid by a liquid. It is less commonly understood that the same phenomenology often

The Boltzmann Project

February 5, 2018
Author(s)
Samuel P. Benz, Joachim Fischer, Bernd Fellmuth, Christof Gaiser, Laurent Pitre, Fernando Sparasci, Lara Risegari, Roberto M. Gavioso, D M. Rippa, Bengt Hallstedt, Jifeng Qu, XiaoJuan Feng, Jianqiang Zhang, David R. White, L Gianfrani, A Castrillo, L Moretti, B Darquie, C Daussy, S Briaudeau, O Kozlova, J J. Segovia, M C. Martin, D del Campo, Michael R. Moldover
The International Committee for Weights and Measures (CIPM), at its meeting in October 2017 followed the recommendation of the Consultative Committee for Units (CCU) on the redefinition of the kilogram, ampere, kelvin and mole. For the redefinition of the

NBTI: Confusion, Frustration, and Promise?

May 2, 2010
Author(s)
Jason P. Campbell
The negative-bias temperature instability (NBTI) is a reliability problem that, in the last ten years, has risen from relative obscurity to become the most important reliability problem in advanced pMOSFET devices. Even though a significant effort has been

Fresh Concrete Rheology - Recent Developments

December 1, 2001
Author(s)
Chiara F. Ferraris, F De Larrard, Nicos Martys
The design of concrete with specified properties for an application is not a new science, but it has taken on a new meaning with the wide use of high performance concretes. The following properties are related to fresh concrete: ease of placement and

Characterizing the thermal effects of High Energy Arc Faults

November 30, 2015
Author(s)
Anthony D. Putorti Jr., Nicholas Melly, Scott Bareham, Joseph E. Praydis
International and domestic operating experience involving High Energy Arc Faults (HEAF) in Nuclear Power Plant (NPP) electrical power systems have demonstrated the potential to cause extensive damage to electrical components and distribution systems along

On the scalability of parametric down-conversion for generating higher-order Fock states

October 18, 2018
Author(s)
Thomas Gerrits, Adriana Lita, Sae Woo Nam, Johannes Tiedau, Tim J. Bartley, Georg Harder, Christine Silberhorn
Spontaneous parametric down-conversion (SPDC) is the most widely-used method to generate higher-order Fock states (n>2). Yet, a consistent performance analysis from fundamental principles is missing. Here we address this problem by analyzing state fidelity

Identifying spurious modes in RF-MEMS resonators using photoelastic imaging

January 21, 2018
Author(s)
Vikrant J. Gokhale, Jason J. Gorman
This paper reports the first use of dynamic photoelastic imaging for identifying in-plane vibration modes in high-frequency MEMS resonators. In a set of width-extensional mode resonators (WE-BARs), we map fundamental width-extensional modes and unwanted

Calibration-Kit Design for Millimeter-Wave Silicon Integrated Circuits

Author(s)
Dylan F. Williams, Phillip Corson, Sharma Jahnavi, Krishnaswamy Harish, Tai Wei, George Zacharias, Ricketts David, Watson Paul, Dacquay Eric, Voinigescu Sorin
… lines with meshed ground plane. We also develop a gold plating process that greatly improves contact repeatability, …

Broadband Emissivity Calibration of Highly Reflective Samples at Cryogenic Temperatures

October 15, 2012
Author(s)
Solomon I. Woods, Timothy M. Jung, Greg Ly, Simon G. Kaplan, Jie Yu
We have developed a technique for calibrating the broadband optical emissivity of high reflectivity samples at cryogenic temperatures. This measurement method employs a primary standard optical detector with high absorptance from visible wavelengths to

Extension and new level optimization of the Ne IV spectrum

January 13, 2012
Author(s)
Alexander Kramida, C M. Brown, Uri Feldman, Joseph Reader
Spectra of Ne emitted by a Penning discharge were recorded in the extreme ultraviolet (EUV) region between 140 Å and 359 Å on a 10.7 m grazing-incidence spectrograph with phosphor storage image plates. These spectra provided 33 newly identified lines of Ne

An interferometric platform for studying AFM probe deflection

January 3, 2011
Author(s)
Jon R. Pratt, Lee Kumanchik, Tony L. Schmitz
This paper describes an interferometric platform for measuring the full-field deflection of atomic force microscope (AFM) probes and generic cantilevers during quasi-static loading. The platform consists of a scanning white light interferometer (SWLI)

REFLECTIVITY STUDIES OF PASSIVE MICROWAVE CALIBRATION TARGETS AND ABSORPTIVE MATERIALS

July 30, 2010
Author(s)
Dazhen Gu, Amanda Cox, Derek A. Houtz, Dave K. Walker, James P. Randa, Robert L. Billinger
We report the characterization of blackbody reflections as a part of the recent progress on the development of brightness standards for microwave remote sensing at National Institute of Standards and Technology (NIST).Three blackbody targets at variable

Non-Contact Temperature Measurements of Micro-Scale Phenomena

October 16, 2008
Author(s)
Howard W. Yoon
Imaging trying to make temprature measurements in a spatial region equal to the edge of a printer paper or within the diameter of a strand of hair. The accurate computer modeling of the machining process requires measurements of the thermodynamic
