Experts Evaluate Pulsed Laser Deposition Technology

February 19, 2017

Author(s)

John W. Hastie, D W. Bonnell, D Chrissey

The National Institute of Standards and Technology (NIST, Gaithersburg, MD) and The Naval Research Laboratory (NRL, Washington, DC) jointly hosted a workshop entitled Pulsed Laser Deposition (PLD) Technological Barriers: Research Needs and Opportunities

High Temperature Mass Spectrometry: Accuracy of the Method and Influence of Ionization Cross Sections, for the Determination of Thermodynamic Properties

April 18, 2005

Author(s)

John W. Hastie, D W. Bonnell, C Chatillon, J Drowart

An assessment of the high temperature mass spectrometric technique is given, with emphasis on sources of inaccuracy, particularly ionization cross sections. Data -- experimental, calculated, and estimated -- are summarized for ionization cross sections of

Laser-Assisted Vaporization Mass Spectrometry: Application to Thermochemistry at Very High Temperature

September 1, 2001

Author(s)

John W. Hastie, D W. Bonnell, Peter K. Schenck

Classical mass spectrometically-based approaches to the determination of high temperature thermochemical data and functions are limited in their applicable ranges of temperature and vapor pressure. An earlier laser-based mass spectrometric approach

Treasure of the Past: Molecular Basis of Flame Inhibition

A Predictive Ionization Cross Section Model for Inorganic Molecules

July 1, 2001

Author(s)

John W. Hastie

To resolve a long-standing lack of experimental data for electron impact ionization cross sections for inorganic molecules, or the availability of a reliable predictive method, we have developed a modified classical model. The model relies on the know or

Application of a New Thermochemical Measurement Method for Nuclear Materials at Temperatures Beyond 3000k

April 1, 2001

Author(s)

John W. Hastie, D W. Bonnell, Peter K. Schenck

In processing and end-use environments, and particularly nuclear fission reactor excursions, inorganic materials can be subjected to temperatures where liquids and vapors are significant components of the materials system. Classical characterization and

Development and Application of Very High Temperature Mass Spectrometry: Vapor Pressure Determinations Over Liquid Refractories

November 1, 2000

Author(s)

John W. Hastie, D W. Bonnell, Peter K. Schenck

Existing thermodynamic and vaporization data for liquid refractories are based either on estimates or on data extrapolated from studies on the solids obtained at much lower temperatures. Previously we have shown that pulsed laser heating, coupled with time
