Electric charge definition, one of the basic properties of the elementary particles of matter giving rise to all electric and magnetic forces and interactions. The two kinds of charge are given negative and positive algebraic signs: measured in coulombs. Triboluminescence Luminescence is defined as the emission of visible radiation due to some external cause other than heat. Triboluminescence is light that is produced by pressure, friction, or mechanical shock. It may be readily demonstrated with two hand-sized milky quartz crystals in a darkened room.

Principal studies of the physical and chemical properties of spicules of hexactinellid sponges are carried out on basal monoaxonic megascleres, which are diactine or pentactine spicules with a hypertrophied proximal ray and reduced other rays. The principal function of the spicules of hexactinellids is certainly a skeletal one. Calcite is a beautiful gem that is doubly refractive and available in many colors. Calcite is very highly reactive to even the weakest of acids such as vinegar. Other important properties of Calcite are its fluorescence, phosphorescence, thermoluminescence and triboluminescence.

Fracto-Emission or Triboluminescence. Fracto-emission (FE) is the emission of particles and photons before, during, and following the propagation of a crack in a stressed material. Particles include electrons, ions, and neutral atoms and molecules. Light emission under mechanical stimulation is often called triboluminescence (TL). Grinding and breaking of crystal and glasses can produce FE.
