Double layer
Encyclopedia
Double layer may refer to:
- Double layer (plasma)Double layer (plasma)A double layer is a structure in a plasma and consists of two parallel layers with opposite electrical charge. The sheets of charge cause a strong electric field and a correspondingly sharp change in voltage across the double layer. Ions and electrons which enter the double layer are accelerated,...
, a structure in a plasma and consists of two parallel layers with opposite electrical charge - Double layer (interfacial)Double layer (interfacial)A double layer is a structure that appears on the surface of an object when it is placed into a liquid. The object might be a solid particle, a gas bubble, a liquid droplet, or a porous body. The DL refers to two parallel layers of charge surrounding the object...
, a structure that appears on the surface of an object when it is placed into a liquid - Double layer (biospecific)Double layer (biospecific)In biological systems, a double layer is the surface where two different phases of matter are in contact. Biological double layers are much like their interfacial counterparts, but with several notable distinctions....
, the surface where two different phases of matter are in contact - DVD+R DLDVD+R DLDVD+R DL also called DVD+R9, is a derivative of the DVD+R format created by the DVD+RW Alliance. Its use was first demonstrated in October 2003. DVD+R DL discs employ two recordable dye layers, each capable of storing nearly the 4.7 GB capacity of a single-layer disc, almost doubling the total...
