The thermophysical properties (decomposition temperature, glass transition temperature, density, and viscosity) of imidazolium-based ionic liquids (ILs) paired with the tricyanomethanide ([TCM]−) anion and the bis(trifluoromethylsulfonyl)imide ([Tf2N]−) anion were...
Carbon Dioxide Solubilities and Diffusivities in 1-Alkyl-3-methylimidazolium Tricyanomethanide Ionic Liquids: An Experimental and Modeling Study
The solubility and diffusivity of CO2 in a series of 1-alkyl-3methylimidazolium tricyanomethanide ionic liquids ([Cnmim][TCM] with n = 2, 4, 6, 7, 8; ILs) was studied using a magnetic suspension balance at temperatures ranging from 298 to 353 K and pressures up to 2...
Experimental and Molecular Dynamics Simulation Study on Thermal, Transport, and Rheological Properties of Asphalt
The purpose of this study was to evaluate the thermal (glass transition temperature), transport (self-diffusion), and rheological (viscosity, storage and loss modulus) properties of asphalt via laboratory experiments and molecular dynamics simulations. A 12-component...
Chameleon: A Generalized, Connectivity Altering Software for Tackling Properties of Realistic Polymer Systems
Chameleon, a generalized Monte Carlo software for the phase space analysis of complex, realistic polymer systems is presented. Chameleon implements the so-called connectivity altering technique applied on polymer chains through Monte Carlo moves that do not mimic...
Molecular Dynamics Simulation of Pure n -Alkanes and Their Mixtures at Elevated Temperatures Using Atomistic and Coarse-Grained Force Fields
The properties of higher n-alkanes and their mixtures is a topic of significant interest for the oil and chemical industry. However, the experimental data at high temperatures are scarce. The present study focuses on simulating n-dodecane, n-octacosane, their binary...
Generation and Properties of the New Asphalt Binder Model Using Molecular Dynamics (MD)
Asphalt binder is the main material for road pavement and building construction. It is a complex mixture composed of a large number of hydrocarbons with different molecular weights. The study of asphalt binders and asphalt concretes from a molecular perspective is an...
Molecular Dynamics Simulation of the n-Octacosane–Water Mixture Confined in Graphene Mesopores: Comparison of Atomistic and Coarse-Grained Calculations and the Effect of Catalyst Nanoparticle
Fischer–Tropsch synthesis (FTS) is used extensively in the gas-to-liquids (GTL) process to produce clean, high-quality low emission transportation fuels from synthesis gas. In order to gain a better understanding of the phase behavior of the produced wax–water...
