Absorption Spectra of Martian Dust Simulants

February 18, 2022

Author(s)

James Radney, Christopher D. Zangmeister

Understanding the climate of Mars requires a detailed understanding of the optical properties of Martian dust as it is a ubiquitous component of the atmosphere. The need for a consensus motivates measurements of terrestrial simulants under controlled

Data-driven matching of experimental crystal structures and gas adsorption isotherms of metal-organic frameworks

February 17, 2022

Author(s)

Daniele Ongari, Leopold Talirz, Kevin Maik Jablonka, Daniel Siderius, Berend Smit

Porous metal-organic frameworks are a class of materials with great promise in gas separation and gas storage applications. Due to the large material space, computational screening techniques have long been an important part of the scientific toolbox

Thermodynamically stable colloidal solids: interfacial thermodynamics from the particle size distribution

February 3, 2022

Author(s)

Andrew Nelson, Lawrence Henry Friedman

True thermodynamic stability of a solid colloidal dispersion is generally unexpected, so much so that a thorough experimental validation of proposed stable systems remains incomplete. Such dispersions are underinvestigated and would be of interest because

Speed of Sound Measurements of Binary Mixtures of Difluoromethane (R-32) with 2,3,3,3-Tetrafluoropropene (R-1234yf) or trans-1,3,3,3-Tetrafluoropropene (R-1234ze(E)) Refrigerants

January 29, 2022

Author(s)

Aaron Rowane, Richard A. Perkins

Sound speed data measured using a dual-path pulse-echo instrument are reported for binary mixtures of difluoromethane (R-32) with 2,3,3,3-tetrafluoropropene (R-1234yf) or trans-1,3,3,3-tetrafluoropropene (R-1234ze(E)). The sound speed is reported at two

Digitization of Adsorption Isotherms from "The Thermodynamics and Hysteresis of Adsorption"

December 16, 2021

Author(s)

Daniel Siderius

Sorption isotherms collected from tables in the seminal dissertation, "The Thermodynamics and Hysteresis of Adsorption" by A. J. Brown, have been digitized and made publicly available, along with supporting software scripts that facilitates usage of the

A thermodynamics-guided framework to design lightweight aggregate from waste coal combustion fly ash

November 16, 2021

Author(s)

Mohammad Balapour, Thiha Thway, Rathin Rao, Grace Hsuan, Yaghoob Franam, Newell Moser, Edward Garboczi

In this study, a systematic thermodynamics-based framework was applied to recycle waste low and high-calcium coal combustion Fly Ash (FA) into synthetic lightweight aggregates (LWA) through sintering. The process to successfully manufacture synthetic LWA

Ethanol and Water Adsorption in Conventional and Hierarchical All-Silica MFI Zeolites

November 16, 2021

Author(s)

Swagata Pahari, Matheus Dorneles de Mello, Mansi Shah, Tyler Josephson, Huong Giang Nguyen, Limin Ren, Roger D. van Zee, Michael Tsapatsis, J. Ilja Siepmann

Hierarchical zeolites containing both micro- ( 700 g L−1), the SPP material becomes selective for water over ethanol.

Equations of State for the Thermodynamic Properties of Three Isomeric Hexanes: 3-Methylpentane, 2,2-Dimethylbutane, and 2,3-Dimethylbutane

November 12, 2021

Author(s)

Eric W. Lemmon, Kehui Gao, Jiangtao Wu

Equations of state for three isomeric hexanes, 3-methylpentane, 2,2-dimethylbutane, and 2,3- dimethylbutane, have been developed, which are based on experimental thermodynamic property data from the literature. These equations are explicit in the Helmholtz

Equations of State for the Thermodynamic Properties of Three Perfluorocarbons: n-Perfluorobutane, n-Perfluoropentane, and n-Perfluorohexane

November 9, 2021

Author(s)

Kehui Gao, Eric W. Lemmon, Andreas Koester, Monika Thol, Jiangtao Wu

Helmholtz energy equations of state with independent variables of temperature and density were developed for n-perfluorobutane, n-perfluoropentane, and n-perfluorohexane based on experimental thermodynamic property data from the literature and simulation

Quantum-Based Photonic Sensors for Pressure, Vacuum, and Temperature Measurements: A Vison of the Future with NIST on a Chip

September 17, 2021

Author(s)

Jay H. Hendricks, Zeeshan Ahmed, Daniel Barker, Kevin O. Douglass, Stephen Eckel, James A. Fedchak, Nikolai Klimov, Jacob Edmond Ricker, Julia Scherschligt

The NIST on a Chip (NOAC) program's central idea is the idea that measurement technology can be developed to enable metrology to be performed "outside the National Metrology Institute" by the crea-tion of deployed and often miniaturized standards. These

Total protein quantitation using the bicinchoninic acid (BCA) assay and gradient elution moving boundary electrophoresis (GEMBE)

September 8, 2021

Author(s)

Jason Kralj, Matt S. Munson, David J. Ross

We investigated using gradient elution moving boundary electrophoresis (GEMBE) and capacitively- coupled contactless conductivity detection (C4D) to assay total protein concentration using the BCA reaction. We chose this format because GEMBE is

Recommendation system to predict missing adsorption properties of nanoporous materials

September 7, 2021

Author(s)

Arni Sturluson, Ali Raza, Grant McConachie, Daniel Siderius, Xaioli Fern, Cory Simon

Nanoporous materials (NPMs) selectively adsorb and concentrate gases into their pores and thus could be used to store, capture, and sense many different gases. Modularly synthesized classes of NPMs, such as covalent organic frameworks (COFs), offer a large
