Defining Excipients â¢ Excipients are defined like any other material â¢ Excipients are often multi-substance ingredients (colorants, flavors, fragrances) â Each substance should be defined â¢ Excipients are often the most difficult substances to define â No official naming body that defines most excipients â Insufficient information in pharmacopeias â Manufactures are inconsistent in the type information
Phases Â· Phase transition Â· QCP. An exciton is a bound state of an electron and an electron hole which are attracted to each other by the electrostatic Coulomb force. It is an electrically neutral quasiparticle that exists in insulators, semiconductors and in some liquids. The exciton is regarded as an elementary excitation of condensed matter that can transport energy without transporting net electric charge. An exciton can form when a photon is absorbed by a semiconductor. This excites an electron from the valence band into t
