Prediction of the enthalpies of vaporization for roomerature ionic liquids: Correlations and a substitution-based additive scheme

© 2015 Elsevier B.V. All rights reserved. The literature data on the enthalpies of vaporization for aprotic ionic liquids (ILs) published by the end of May 2014 were analyzed and the most reliable ΔlgHm values were derived for 68 ILs. The selected enthalpies of vaporization were correlated with density and surface tension using symbolic regression and a number of effective correlation equations were proposed. The substitution-based incremental scheme for prediction of the enthalpies of vaporization of imidazolium, pyridinium and pyrrolidinium ILs was developed. The standard error of the regression for the developed scheme is significantly lower than that for the atom-based group-contribution schemes proposed earlier

Thermodynamic similarity of stacked-cup multiwall carbon nanotubes and graphite

When conducting photo elicitation interviews (PEI), researchers introduce photographs into the interview context. Although PEI has been employed across a wide variety of disciplines and participants, little has been written about the use of photographs in interviews with children. In this article, the authors review the use of PEI in a research study that explored the perspectives on camp of children with cancer. In particular, they review some of the methodological and ethical challenges, including (a) who should take the photographs and (b) how the photographs should be integrated into the interview. Although some limitations exist, PEI in its various forms can challenge participants, trigger memory, lead to new perspectives, and assist with building trust and rapport
