6. THERMODYNAMIC PROPERTIES OF PURE GASES AND LIQUIDS

February 7, 2023
Author(s)
Vladimir Diky, Rich Elliott
Methods are presented in this chapter foremost for estimating the volumetric behavior of pure gases and liquids as a function of temperature and pressure. Relationships between P, V, and T are formally known as equations of state (EOSs).

7. THERMODYNAMIC PROPERTIES OF MIXTURES

February 7, 2023
Author(s)
Rich Elliott, Vladimir Diky
Methods are presented in this chapter to estimate the volumetric, enthalpic, and entropic properties and their derivatives for mixtures of gases and liquids as a function of temperature, pressure, and composition as expressed in mole, mass, or volume

CHAPTER NINE. SPECIALIZED PHASE BEHAVIOR IN MIXTURES

February 7, 2023
Author(s)
Vladimir Diky, Rich Elliott
Vapor liquid equilibrium (VLE) in mixtures is strongly influenced by the vapor pressures of the pure components, especially when one compound is highly concentrated. This means that the bubble pressure is relatively insensitive to infinite dilution

Properties of Gases and Liquids. Chapter 3. Pure-component constants

February 7, 2023
Author(s)
Vladimir Diky, Thomas Knotts, Vincent Wilding, Rich Elliott
The properties of pure components are important for all aspects of process design and optimization. Pure-component properties also underlie much of the observed behavior of mixtures. For example, property models intended for the whole range of composition

Sustainable Additive Manufacturing of Polyelectrolyte Photopolymer Complexes

January 29, 2023
Author(s)
Thomas Kolibaba, Jason Killgore, Callie Higgins
Polyelectrolyte complexes (PECs), assemblies of oppositely charged polymers with powerful properties and wide-ranging applications, are currently not melt-processable via any conventional means and have been limited commercially to applications only as

Field-Deployable Devices

January 1, 2023
Author(s)
Thomas P. Forbes, Raychelle Burks
Reductions in instrument size, weight, and power continue to facilitate the development and application of field-deployable devices for investigative purposes. Portable analytical instrumentation supporting the rapid and reliable identification of two

Isotope Dilution Mass Spectrometry as an Independent Assessment for Mass Measurements of Milligram Quantities of Aqueous Solution

January 1, 2023
Author(s)
Richard Essex, Jacqueline L. Mann, Denis E. Bergeron, Ryan P. Fitzgerald, Svetlana Nour, Gordon A. Shaw, R. Michael Verkouteren
Isotope dilution mass spectrometry was used to independently assess the accuracy of mass measurement methods developed to quantitatively dispense milligram quantities of aqueous solution. Solutions of isotopically enriched 158Gd and enriched 155Gd were

Development of an Improved Standard Reference Material for Folate Vitamers in Human Serum

December 12, 2022
Author(s)
Johanna Camara, Jeanita Pritchett, Yasmine Daniels, Mary Bedner, Michael Nelson, Mark Lowenthal, Zia Fazili, Christine Pfeiffer, Karen W. Phinney, Katherine E. Sharpless, Lane C. Sander, Katrice Lippa, James H. Yen, Adam Kuszak, Stephen Wise
The US National Institute of Standards and Technology (NIST) developed a Standard Reference Material® (SRM®) 3949 Folate Vitamers in Frozen Human Serum to replace SRM 1955 Homocysteine and Folate in Human Serum. The presence of increased endogenous levels
