Holes in a P-side region near to the interface are also gone by a similar reason. As a result, majority charge carriers (free electrons for the N-type semiconductor, and holes for the P-type semiconductor) are depleted in the region around the junction interface, so this region is called the depletion region or depletion zone. Due to the ...
The depletion of resources has been an issue since the beginning of the 19th century amidst the First Industrial Revolution.The extraction of both renewable and non-renewable resources increased drastically, much further than thought possible pre-industrialization, due to the technological advancements and economic development that lead to an increased demand for natural resources.
Depleted uranium; Ego depletion, idea that self-control or willpower draws upon a limited pool of mental resources that can be used up; Depletion (accounting), an accounting and tax concept used in mining, timber, petroleum, or other similar industries; T-cell depletion, process of T cell removal or reduction
When natural habitats are destroyed or natural resources are depleted, the environment is degraded; direct environmental degradation, such as deforestation, which is readily visible; this can be caused by more indirect process, such as the build up of plastic pollution over time or the buildup of greenhouse gases that causes tipping points in ...
Ozone depleting chemicals are also often greenhouse gases. The increases in concentrations of these chemicals have produced 0.34 ± 0.03 W/m 2 of radiative forcing, corresponding to about 14 percent of the total radiative forcing from increases in the concentrations of well-mixed greenhouse gases.

A depletion force is an effective attractive force that arises between large colloidal particles that are suspended in a dilute solution of depletants, which are smaller solutes that are preferentially excluded from the vicinity of the large particles.
The ozone depletion potential (ODP) of a chemical compound is the relative amount of degradation to the ozone layer it can cause, with trichlorofluoromethane (R-11 or CFC-11) being fixed at an ODP of 1.0.
