Heat capacity of stacked-cup multiwalled carbon nanotubes (CNT) was measured in an adiabatic calorimeter over the temperature range (5 to 370) K. Results are compared with literature data on various samples of CNT and other carbon allotropes. The
In the highest-accuracy mixture models available today, those of the multi-fluid Helmholtz-energy-explicit formulation, there are a number of binary interaction parameters that must be obtained through correlation or estimation schemes. These binary

The identification of improved carbon dioxide (CO2) capture solvents remains a challenge due to the vast number of potentially-suitable molecules. We propose an optimization-based computer- aided molecular design (CAMD) method to identify and select, from

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
Psychrometric properties of humid air are widely used in the analysis and modeling of thermal systems. In this work we present a method for obtaining these properties from the multi-fluid mixture formulation forming the so-called GERG mixture model. This

Stable and metastable crystal phases of 1-butyl-3-methylimidazolium hexafluorophosphate were obtained in an adiabatic calorimeter providing precise temperature control during crystallization. Heat capacities and temperatures and enthalpies of phase
The thermodynamic principles that pertain to both chemical and overall biochemical reactions are discussed with particular emphasis on enzyme-catalyzed reactions. Chemical reactions involve specific species (which may also be biochemical importance) and

Cubic colloids, sedimented on a surface and immersed in a solution of depletant molecules, were modeled with a family of shapes which smoothly varies from squares to circles. Using Wang-Landau simulations with expanded ensembles, we observe the formation

Trimers with one attractive bead and two repulsive beads, similar to recently synthesized trimer patchy colloids, were simulated with flat-histogram Monte Carlo methods to obtain the stable self-assembled structures for different shapes and interaction

The thermodynamic temperature of the point of inflection of the melting transition of Re-C, Pt-C and Co-C eutectics has been determined to be 2747.84±0.35 K, 2011.43±0.18K and 1597.39±0.13 K, respectively, and the thermodynamic temperature of the freezing

The speed of sound of two (argon + carbon dioxide) mixtures was measured over the temperature range from (275 to 500) K with pressures up to 8 MPa utilizing a spherical acoustic resonator. The compositions of the gravimetrically prepared mixtures were (0
We explore a novel method for determining the dew-point density and dew-point pressure of fluid mixtures and compare it to traditional methods. The (p, ρ, T, x) behavior of three (methane + propane) mixtures was investigated with a two-sinker magnetic
