Virtual Testing of Ready-Mixed Concrete

January 1, 2004
Author(s)
Jeffrey W. Bullard
The development of a virtual testing system is no small task. It requires fundamental scientific research into the physics, chemistry, and materials science of concrete. The Virtual Cement and Concrete Testing Laboratory consortium has identified three

Trapped-Ion Quantum Simulator,

January 1, 1998
Author(s)
David J. Wineland, C Monroe, Wayne M. Itano, B E. King, Dietrich G. Leibfried, C J. Myatt, Chris S. Wood
Coherent manipulations involving the quantized motional and internal states of a single trapped ion can be used to simulate the dynamics of other systems. We consider some examples, including the action of a Mach Zehnder interferometer which uses entangled

Elastic Flexure of Bilayered Beams Subject to Strain Differentials

December 1, 2000
Author(s)
Tze J. Chuang, S K. Lee
The residual stresses present in a thin film and the curvatures formed at its substyrate during deposition have been a great concern to electrochemists and process engineers. Here a new hybrid analytical method is presented to reanalyze the flexural

On neutron holography, neutron interferometry, and neutron orbital angular momentum

September 26, 2025
Author(s)
Wolfgang Treimer, Frank Hausser, Ingeborg Beckers, Suda Martin, Terrence Jach
A neutron Laue crystal interferometer has been reported by Saranac et al . to demonstrate neutron holography of a spiral phase plate. Using its two coherent beams as the object and reference beams, the resulting interference pattern was interpreted as a

Operando analysis of the positive active mass of lead batteries by neutron diffraction

January 30, 2024
Author(s)
Miguel Rodriuqez-Goemz, Javier Campo, Aloida Orera, Fernando de La Fuente, Jesus Valenciano, Holger Fricke, Yan Chen, Ke An, Daniel Hussey, Angel Larrea
We have analysed, through neutron diffraction experiments with the volume-gauge technique, the in operando performance of lead cells composed of industrial positive and negative electrodes, previously tank formed in the manufacturing plant. The cells, 6.5

X-Ray Spectrometer Having 12 000 Resolving Power at 8 keV Energy

May 14, 2018
Author(s)
Lawrence T. Hudson, John F. Seely, Uri Feldman, Albert Henins
An x-ray spectrometer employing a thin (50 μm) silicon transmission crystal was used to record high-resolution Cu Kα spectra from a laboratory x-ray source. The diffraction was from the (331) planes that were at an angle of 13.26° to the crystal surface

Testing of Cementitious Materials Using a Dynamic MEMS Micro Rheometer

May 17, 2016
Author(s)
Yong Sik Kim, Nicholas G. Dagalakis, Chiara C. Ferraris, Nicos Martys
Incompatibility of cementitious materials with admixtures often requires time consuming testing. Usually, several mixtures need to be prepared either using concrete or paste to determine the optimum high range water reducer dosage (HRWRA) and type. The

Forward Issue on Electrochemical Processing of Interconnects

December 10, 2013
Author(s)
Thomas P. Moffat, Daniel Josell
On-going densification of microelectronics has driven the development of cost effective and reliable processes for fabricating circuitry ranging from nanometer scale trenches and vias for on-chip interconnects to micrometer scale through-silicon-vias (TSV)

Development of a MEMS based Dynamic Rheometer

August 31, 2010
Author(s)
Gordon Christopher, Jae M. Yoo, Nicholas G. Dagalakis, Steven D. Hudson, Kalman D. Migler
Rheological methods that interrogate nano-liter scale volumes of fluids and solids have advanced considerably over the past decade, yet there remains a need for methods that probe the frequency dependent complex rheological moduli through application of

Electrodeposition of Metastable Au-Ni Alloys

May 13, 2010
Author(s)
Gery R. Stafford, E. Rouya, Ugo Bertocci, J. J. Mallett, R. Schad, M. R. Begley, R. G. Kelly, M. Reed, G. Zangari
… electrolytes derived from a commercial bath for soft gold plating is investigated. Alloy compositions ranging from 0 to …

Cracking in Brittle Laminates from Concentrated Loads

June 1, 2002
Author(s)
H Chai, Brian R. Lawn
A study is made of the crack resistance of multilaminates consisting of brittle layers interleaved with compliant interlayers and bonded to compliant substrates. Specific attention is paid to flexure generated radial cracks in the undersurfaces of

Carbon Nanotube-Based Black Coatings

February 15, 2018
Author(s)
John H. Lehman, Christopher S. Yung, Nathan A. Tomlin, Davis R. Conklin, Michelle S. Stephens
… We briefly describe a history of other coatings such as nickel phosphorous, gold black and carbon-based paints and …
