Phase diagram can be constructed that show the effect of more than two variables on the phase of a substance. Phase diagrams can use other variables in addition to or in place of temperature, pressure and composition, for example the strength of an applied electrical or magnetic field, and they can also involve substances that take on more than just three states of matter. One type of phase diagram plots temperature against the relative concentrations of two substances in a mixture called a "binary phase diagram", as shown at right. Such a mixture can be either a solid solution, eutectic or peritectic,
Journal of Physical Chemistry A a further split, with "Journal of Physical Chemistry C" now being dedicated to the burgeoning fields of nanotechnology, molecular electronics, and related subjects. "The Big Bang Theory" character, Sheldon Cooper, fictionally appeared on the cover of one of the journals. Journal of Physical Chemistry A The Journal of Physical Chemistry A is a scientific journal which reports research on the chemistry of molecules - including their dynamics, spectroscopy, kinetics, structure, bonding, and quantum chemistry. It is published weekly by the American Chemical Society. Prior to 1997 the title was simply Journal of Physical Chemistry. Owing to the ever-growing amount of
