A high-efficient and salt-rejecting 2D film for photothermal evaporation

iScience, 2023
Summary: The solar-driven desalination is seen as a sustainable way to combat water scarcity. However, the solar steam generation efficiency has long been restricted by the high vaporization enthalpy of water and low energy density of natural sunlight ...

Estimation of the volatility distribution of organic aerosol combining thermodenuder and isothermal dilution measurements [PDF]

Atmospheric Measurement Techniques, 2017
A method is developed following the work of Grieshop et al. (2009) for the determination of the organic aerosol (OA) volatility distribution combining thermodenuder (TD) and isothermal dilution measurements. The approach was tested in experiments that

The Ionic Product of Water in the Eye of the Quantum Cluster Equilibrium

Molecules, 2022
The theoretical description of water properties continues to be a challenge. Using quantum cluster equilibrium (QCE) theory, we combine state-of-the-art quantum chemistry and statistical thermodynamic methods with the almost historical Clausius–Clapeyron

Vaporization enthalpy prediction of ionic liquids based on back-propagation artificial neural network

Green Chemical Engineering
Vaporization enthalpy (ΔvapH) is a fundamental thermodynamic property of ionic liquids (ILs). Accurate prediction of vaporization enthalpy relies on appropriate mathematical models grounded in precise experimental measurements. The quantitative structure-

Calculating the Enthalpy of Vaporization for Ionic Liquid Clusters

, 2016
Classical atomistic simulations are used to compute the enthalpy of vaporization of a series of ionic liquids composed of 1-alkyl-3-methylimidazolium cations paired with the bis(trifluoromethylsulfonyl)imide anion. The calculations show that the enthalpy
