ABSTRACT
In this manuscript, we present rheology, ionic conductivity, density, chromatography, and life cycle analysis data on the PC+X electrolyte system with and without LiClO4. In particular, the data are presented in contact with Na surfaces. In this case, photographic images of electrolyte-sodium mixtures are also shown. The data was analyzed using OriginPro software to visualize it in an appropriate manner. In our view, the data serve as comparative values, form a basis of a chromatography analysis and are also valuable for modeling. The analysis of the data is presented in the manuscript "Comprehensive characterization of propylene carbonate based liquid electrolyte mixtures for sodium-ion cells" [1].
ABSTRACT
Three undescribed natural products, the anthranilic acid derivatives laccanthrilic acids A, B, and C, as well as the known (3S)-1,2,3,4-tetrahydro-3-ß-carboline-3-carboxylic acid were isolated from fruiting bodies of Laccaria laccata. The structures were established by 1D and 2D NMR spectroscopy, HR-(+)-ESIMS and chemical synthesis. The absolute configuration of laccanthrilic acids A and B was determined by GC-MS after hydrolytic cleavage and derivatisation of the resulting glutamic acid with methanol and Mosher's reagent and subsequent comparison with authentic synthetic samples of known absolute configuration. The absolute configuration of laccanthrilic acid C was determined by comparison of the CD spectra of laccanthrilic acids B and C with each other. Metabolic profiling of related species showed that the compounds are common in the genus Laccaria. Laccanthrilic acid B exhibited moderate nematicidal effects against Caenorhabditis elegans, which might explain to some degree the beneficial role of these fungi for the growth and survival of their host plants.
