A general perception among researchers is that boiling points, which is a key property in the optimization of lubricant performance, are difficult to predict successfully using a single-parameter model. In this contribution, we propose a new graph parame

An example of a small subset of novel applications are spectroscopy, where the thermoacoustic signal might change depending on the composition of a substance (e.g., CO2 sensors25, oil contamination in water26). In Metrology/thermometry, since the thermoacoustic signal amplitude changes with the ...
