The heat capacity of an ethylene glycol (EG)–dimethylsulfoxide (DMSO) liquid system is measured to determine its solvophobic effect. Measurements are made in the temperature range of 300–340 K for pure DMSO and the 0 to ~15 and 50 mol % ranges of

The vertex 3-colourability problem is to verify whether it is possible to split the vertex set of a given graph into three subsets of pairwise nonadjacent vertices or not. This problem is known to be NP-complete for planar graphs of the maximum face
