We present a new strategy to estimate the temperature-dependent vapor-liquid equilibria and solvation free energies of dilute neutral molecules based on only their estimated solvation energy and enthalpy at 298 K. These two pieces of information coupled with matching conditions between the functional forms developed by Japas and Levelt Sengers for near critical conditions and by Harvey for low and moderate temperature conditions allow the fitting of a piecewise function that predicts the temperature-dependent solvation energy for dilute solutes up to the critical temperature of the solvent. If the Abraham and Mintz parameters for the solvent and solute are available or can be estimated from group contributions, this method requires no experimental data and can still provide accurate estimates with an error of about 1.6 kJ/mol. This strategy, which requires minimal computational resources, is shown to compare well with other methods of temperature-dependent solvation free energy prediction.

“…Any mixture belonging to this SLLV region splits into two liquid phases and one solid which boil at a sole temperature and give a single composition of the vapor in equilibrium. However, the 7 points determined by [17] for this SLLV region are inconsistent since there are important differences in their boiling temperatures and in their vapor composition with errors of 2 K and 0.034 mole fraction respectively. On the same Figure 3, the experimental data of [18] have been plotted.…”

“…As shown in the Figure, water and 2propanol are completely miscible but the presence of NaCl can split the mixture into two liquid phases in equilibrium. However, this feature of the splitting of phases in the presence of NaCl is not mentioned or considered in reference [17] when the authors present the results of their detailed study of the LV equilibrium of the system. Figure 3 represents the compositions of liquid phases whose boiling temperatures and vapor compositions were determined by the authors.…”

In this case, all the points of this SLV region placed in the same straight line passing through the vertex corresponding to NaCl split into one liquid and a solid which boil at a specific temperature and give the same vapor composition.…”

IntroductionSoil salinization is a major abiotic stress that imposes high osmotic stress on plant growth, thereby limiting crop productivity. It also acts as an environmental filter for microbes, impacting associated ecosystem services and functions. Agricultural practices such as cover cropping can help mitigate the negative impacts of soil salinity. However, our knowledge of how cover cropping and salinity influence soil microbiome diversity and complexity is limited.Materials & MethodsUsing amplicon sequencing, metagenomics, and network analysis, we aimed to determine if cover cropping can be effective in maintaining microbiome complexity and functioning in salinity‐affected soils. We conducted a field study to determine the soil microbial properties over four locations with salinity (saline: SS, and nonsaline: NS) and cover cropping (cover‐cropped: CC, and no cover‐cropped: NC) treatments. We hypothesized that microbial diversity and complexity will be lower in saline as compared to nonsaline soils, and the reduction can be countered by inclusion of cover crops.ResultsOur results found a significant effect of salinity on the clustering of bacterial communities in soil. However, cover cropping increased bacterial and fungal alpha diversity. Cover cropping increased soil microbial network complexity under both saline and nonsaline conditions. Most of the keystone taxa were members of the order Thermomicrobiales, which are known to enhance stress tolerance in plants. Metagenomics revealed higher activities of genes related to transcription and folate metabolism in saline‐cover crop treatments.ConclusionOur results identify key microbial players under salinity stress and highlight the potential of using cover crops to mitigate the negative effect of salinity on soil microbiomes, which can facilitate sustainable productivity in saline agroecosystems.
