. Ions in water are the liquid of life. Life occurs almost entirely in ‘salt water’. Life began in salty oceans. Animals kept that salt water within them when they moved out of the ocean to drier surroundings. The plasma and blood that surrounds all cells are electrolytes more or less resembling sea water. The plasma inside cells is an electrolyte solution that more or less resembles the sea water in which life began. Water itself (without ions) is lethal to animal cells and damaging for most proteins. Water must contain the right ions in the right amounts if it is to sustain life. Physical chemistry is the language of electrolyte solutions and so physical chemistry, and biology, particularly physiology, have been intertwined since physical chemistry was developed some one hundred fifty years ago. Physiology, of course, was studied by the Greeks some millennia earlier, but the biological role of electrolyte solutionscould not be understood until ions were discovered by chemists some 2,000 years later.

- A new approach to the Lennard-Jones potential and a new model: PNP-steric equations (2014, methodology): “This may support the work of [16, 17, 18, 28] which only use the repulsive term of the LJ potential to describe ionic interactions.”
