  2. Accelerated solvent extraction - Wikipedia

    en.wikipedia.org/wiki/Accelerated_solvent_extraction

    Accelerated solvent extraction (ASE), also known as pressurized solvent extraction (PSE), is a method for extracting various chemicals from a complex solid or semisolid sample matrix. The process uses high temperature and pressure, which results in the extraction taking less time and requiring less solvent, and possibly also giving better ...

  3. Amplified spontaneous emission - Wikipedia

    en.wikipedia.org/wiki/Amplified_spontaneous_emission

    ASE is produced when a laser gain medium is pumped to produce a population inversion. Feedback of the ASE by the laser's optical cavity may produce laser operation if the lasing threshold is reached. Excess ASE is an unwanted effect in lasers, since it is not coherent, and limits the maximum gain that can be achieved in the gain medium. ASE ...

    Study guide from Permacharts. Academic support centers in schools often develop study guides for their students, as do for-profit companies and individual students and professors. Once only found at local five and dime stores the internet brought about a new era of online sites with study material.

  7. Murnaghan equation of state - Wikipedia

    en.wikipedia.org/wiki/Murnaghan_equation_of_state

    The study of the properties of matter under these conditions can be done experimentally through devices such as diamond anvil cell for static pressures, or by subjecting the material to shock waves. It also gave rise to theoretical work to determine the equation of state, that is to say the relations among the different parameters that define ...

  8. Partition function (statistical mechanics) - Wikipedia

    en.wikipedia.org/wiki/Partition_function...

    The energy is replaced by the characteristic potential of that ensemble, the Gibbs Free Energy. The letter Z stands for the German word Zustandssumme , "sum over states". The usefulness of the partition function stems from the fact that the macroscopic thermodynamic quantities of a system can be related to its microscopic details through the ...
