High-Resolution Ultrasonic Thermometer for Radiation Dosimetry

October 12, 2021

Author(s)

Eugene Malyarenko, Joseph Heyman, Heather H. Chen-Mayer, Ronald Tosh

This paper describes recent developments in the area of high-precision This paper describes recent developments in the area of high-precision ultrasonic thermometry with the potential to provide on-site direct determination of radiation dose and its

Highly Phase Stable Modelocked Lasers

October 12, 2021

Author(s)

T M. Fortier, D J. Jones, Jun Ye, Steven T. Cundiff

We report on stabilizing the carrier-envelope phase of modelocked Ti:sapphire lasers. Optimization of the construction of the lasers for ease of phase stabilization is discussed. Results demonstrating long term phase coherence of the generated pulse train

Histopathological Reactions of Calcium Phosphate Cement for Alveolar Ridge Augmentation Containing Hydroxyapatite-Coated Implants in Dog Mandibles

October 12, 2021

Author(s)

A Sugawara, K Fujikawa, S K. Kusama, Shozo Takagi, Laurence Chow

Previous studies have shown that a calcium phosphate cement (CPC), consisting of tetracalcium phosphate and dicalcium phosphate anhydrous, was highly biocompatible and more osteoconductive than presently used hydroxyapatite (Hap)-based materials. The

Homological Metrics for Microstructure Response Fields in Polycrystals

October 12, 2021

Author(s)

Lin-Sien H. Lum, D M. Saylor, Thomas Wanner

Quantitative homological metrics are proposed for characterizing the thermal-elastic response of calcite-based polycrystals. The characterization is based on topological measurements, such as the number of components and the number of handles of a complex

Human Mitochondrial Protein Database: A Resource for Human Mitochondrial Proteomics

October 12, 2021

Author(s)

Veerasamy Ravichandran, A S. Khan, Peter E. Barker, G B. Vasquez, S J. Zullo, Talapady N. Bhat, G L. Gilliland

A publicly available web-based resource, the Human Mitochondrial Protein Database (HMPD), has been developed to unify data from a broad collection of related resources that provides information about human nuclear and mitochondrial-encoded proteins. This

Hydraulically Pumped Cone Fracture in Bilayers With Brittle Coatings

October 12, 2021

Author(s)

H Chai, Brian R. Lawn

An earlier FEM analysis of inner cone cracks in monolithic brittle solids subject to cyclic indentation in liquids is extended to include the case of a brittle layer bonded to a compliant substrate, using a model glass/polycarbonate bilayer system as an

Hydrodynamic Flow in Capillary-Channel Fiber Columns for Liquid Chromatography

October 12, 2021

Author(s)

R Stanelle, Lane C. Sander, R K. Marcus

The evaluation of the basic flow characteristics of capillary-channeled polymer (C-CP) fibers proposed for use as the stationary phases for reversed-phase liquid chromatographic separations has been investigated. Stainless steel HPLC columns packed with

Hydrogel-Immobilized Antibodies for Microfluidic Immunoassays

October 12, 2021

Author(s)

Gloria Thomas, Emad E. El-Giar, Laurie E. Locascio, Michael J. Tarlov

The integration of immunoassays in microfluidic devices is a rapidly developing research area combining the power of immunoassays with the inherent benefits of microfluidics. Here, a general overview of microfluidic-based immunoassays is presented along

Hydrolysis-Controlled Transport of Water in Polymeric Coatings

October 12, 2021

Author(s)

Sanghun Lee, Tinh Nguyen, Jonathan W. Martin, E Byrd

Thermoset acrylic melamine coatings are widely used for exterior structures. These materials are formulated by reacting an acrylic polyol with an alkylated melamine. Because the reactions are reversible, acrylic-melamine coatings tend to hydrolyze during

Hydrosomes: Optically Trapped Femtoliter Containers for Single Molecule Studies and Microfluidics

October 12, 2021

Author(s)

Joseph E. Reiner, Alice M. Crawford, Rani B. Kishore, Lori S. Goldner, M K. Gilson, Kristian Helmerson

We demonstrate a novel technique for creating, manipulating, and combining femtoliter volume chemical containers. Possible uses include creating controlled chemical reactions involving small quantities of reagent, and studying the dynamics of single

Hydroxyapatite Formation in a Calcium Phosphate Cement Under Different Storage Conditions

October 12, 2021

Author(s)

S Hirayama, Shozo Takagi, T Ikemi, Laurence Chow

A water-activated self-hardening calcium phosphate cement (CPC) has been the subject of considerable interest in biomaterials research, especially as a bone graft material. A CPC derived from tetracalcium phosphate (TTCP) and dicalcium phosphate anhydrous

Hyperfine Structure Measurements of Neutral Manganese with Fourier Transform Spectroscopy

October 12, 2021

Author(s)

Richard J. Blackwell-Whitehead, J C. Pickering, O Pearse, Gillian Nave

We report experimental hyperfine structure constants of levels in the neutral manganese atom, measured using Fourier transform spectroscopy of hollow cathode discharges. In total 208 spectral lines of astrophysical interest have been analyzed to obtain

Imidazolium Modified Clay Based ABS Nanocomposites: A Comparison Between Melt-Blending and Solution Sonication Processes

October 12, 2021

Author(s)

M Modesti, S Besco, A Lorenzetti, Mauro Zammarano, V Causin, C Marega, Jeffrey W. Gilman, D M. Fox, Paul C. Trulove, Hugh C. De Long, P H. Maupin

Acrylonitrile-butadiene-styrene (ABS) nanocomposites containing imidazolium-modified montmorillonite have been prepared by melt-blending and solution-sonication in order to study the effects of processing on the morphology and properties of the polymer
