The ThermoData Engine is a software expert system implementing the concept of dynamic data evaluation for thermophysical and thermochemical properties of, primarily, organic compounds. This new release provides a substantially expanded database of

An Analytical Solubility Model for Nitrogen-Methane-Ethane Ternary Mixtures

August 24, 2017
Author(s)
Jason Hartwig, Peter Meyerhofer, Ralph Lorenz, Eric Lemmon
Saturn's moon Titan has surface seas of liquid hydrocarbons and a thick, cold, nitrogen atmosphere, and is a target for future exploration. Critical to the design and operation of vehicles for this environment is knowledge of the amount of dissolved

Viscosity Measurements of R32 and R410A to 350 MPa

August 1, 2017
Author(s)
Arno D. Laesecke, Scott Bair
Viscosity measurements were performed with a falling cylinder viscometer on difluoromethane (R32) and the refrigerant blend R410A (R32+R125 with 50 % by mass) at the temperatures 313.15 K, 348.15 K, and 393.15 K with pressures to 350 MPa. The measurement

Rapid Wafer-Scale Growth of Polycrystalline 2H-MoS2 by Pulsed Metalorganic Chemical Vapor Deposition

July 12, 2017

Berc Kalanyan, William A. Kimes, Ryan Beams, Stephan J. Stranick, Elias J. Garratt, Irina Kalish, Albert Davydov, Ravindra Kanjolia, James E. Maslar
High volume manufacturing of devices based on transition metal dichalcogenide (TMD) ultra-thin films will require deposition techniques that are capable of reproducible wafer-scale growth with monolayer control. To date, TMD growth efforts have largely

Connection between thermodynamics and dynamics of simple fluids in pores: impact of fluid-fluid interaction range and fluid-solid interaction strength

July 5, 2017
Author(s)
William P. Krekelberg, Daniel W. Siderius, Vincent K. Shen, Thomas M. Truskett, Jeffrey R. Errington
Using molecular simulations, we investigate how the range of fluid-fluid (adsorbate-adsorbate) interactions and the strength of fluid-solid (adsorbate-adsorbent) interactions impact the strong connection between distinct adsorptive regimes and distinct

Application of the Advanced Distillation Curve Method to the Comparison of Diesel Fuel Oxygenates: 2,5,7,10-Tetraoxaundecane (TOU), 2,4,7,9-Tetraoxadecane (TOD), and Ethanol/Fatty Acid Methyl Ester (FAME) Mixtures

Although they are amongst the most efficient engine types, compression-ignition engines have difficulties achieving acceptable particulate emission and NOx formation. Indeed, catalytic after-treatment of diesel exhaust has become common and current efforts

Correlations for the Viscosity and Thermal Conductivity of Ethyl Fluoride (R161)

May 17, 2017
Author(s)
Ch. M. Tsolakidou, Marc J. Assael, Marcia L. Huber, Richard A. Perkins
This paper presents new wide-ranging correlations for the viscosity and thermal conductivity of ethyl fluoride (R161) based on critically evaluated experimental data. The correlations are designed to be used with a recently published equation of state that

Reference Correlation for the Viscosity of Carbon Dioxide

March 21, 2017
Author(s)
Arno D. Laesecke, Chris D. Muzny
A comprehensive database of experimental and computed data for the viscosity of carbon dioxide (CO2) was compiled and a new reference correlation was developed. Literature results based on an ab initio potential energy surface were the foundation of the

Modulus--Pressure Equation for Confined Fluids

October 28, 2016
Author(s)
Daniel W. Siderius, Gennady Y. Gor, Vincent K. Shen, Noam Bernstein
Ultrasonic experiments allow one to measure the elastic modulus of bulk solid or fluid samples. Recently such experiments have been carried out on fluid-saturated nanoporous glass to probe the modulus of a confined fluid. In our previous work (J. Chem

Determination of the Thermodynamic Properties of Water from the Speed of Sound

October 21, 2016
Author(s)
J. P. Martin Trusler, Eric Lemmon
Thermodynamic properties of compressed liquids may be obtained from measurements of the speed of sound by means of thermodynamic integration subject to initial values of density and isobaric specific heat capacity along a single low-pressure isobar. In

Reference Correlations of the Thermal Conductivity of Ethylene and Propylene

August 9, 2016
Author(s)
A. Koutian, Marc J. Assael, Marcia L. Huber, Richard A. Perkins
New, wide-range reference equations for the thermal conductivity of ethylene and propylene as a function of temperature and density are presented. The equations are based in part upon a body of experimental data that has been critically assessed for

Thermophysical Properties of the Marine Microalgae Nannochloropsis salina

July 15, 2016
Author(s)
Nico Schneider, Tara Fortin, Roland Span, Mandy Gerber
Algae have a variety of uses, including pharmaceutical and cosmetic products, and as a potential energy source in the form of biodiesel, bioethanol and biogas. To optimize the commercial production and use of algal biomass, production facilities have to be

A Helmholtz Energy Equation of State for Sulfur Dioxide

June 9, 2016
Author(s)
Kehui Gao, Jiangtao Wu, Penggang Zhang, Eric Lemmon
A Helmholtz energy equation of state with independent variables of temperature and density was developed for sulfur dioxide (SO2) based on thermodynamic property data from the literature. The equation of state is valid from the triple-point temperature of
