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 Materials Chemistry A family of journals is currently Nazario Martin. The deputy editor-in-chief for "Journal of Materials Chemistry A" is Anders Hagfeldt, while the executive editor is Sam Keltie. The journal is abstracted and indexed in the Science Citation Index, Current Contents/Physical, Chemical & Earth Sciences, and Current Contents/Engineering, Computing & Technology. Journal of Materials Chemistry A The Journal of Materials Chemistry A is a weekly peer-reviewed scientific journal that covers the synthesis, properties, and applications of novel materials related to energy and sustainability. It is one of three journals created after the "Journal of Materials Chemistry" was split at the end of
