Double layer

Double layer logo #21000[biospecific] In biological systems, a double layer (DL) 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 of biological cells carry many different types of chemical groups, each with a different dissoc...

Double layer

Double layer logo #21000[interfacial] A double layer (DL, also called an electrical double layer, EDL) is a structure that appears on the surface of an object when it is exposed to a fluid. 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. The first layer, ...

Double layer

Double layer logo #21000[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 (electrical potential) across the double layer. Ions and electrons which enter the double layer are accelerated, decelerated,...

double layer

double layer logo #20742The interface between an eletrode or a suspended particle and an electrolyte created by charge-charge interaction (charge separation) leading to an alignment of oppositely charged ions at the surface of the electrode or particle. The simplest model is represented by a parallel plate condenser of 2 x 10-8 cm in thickness. In general the e...

An excess or deficiency of electrons on the surface (charge, not to be confused with the transmembrane potential) leads to an equivalent excess of ions of the opposite charge in the surrounding fluid. For most cells, that have negative c...

double layer logo #10444The zone adjacent to a charged particle in which the potential falls effectively to zero. An excess or deficiency of electrons on the surface (charge; not to be confused with the transmembrane potential) leads to an equivalent excess of ions of the opposite charge in the surrounding fluid. For most cells, that have negative charges, there will be an excess of cations immediately adjacent to the plasma membrane, and at physiological ionic strength the double layer is likely to be around 2-3nm thick. ...

Double layer logo #20609A Single-sided, dual-layer DVD holds 8.5 GB of data. This unique format allows both moulded DVD data halves to be read from the same side of the disc by using a clear bonding agent, a semi-reflective metal layer on the first data disc and by adjusting the focus point of the player to read two layers. A single-sided, dual-layer Blu-ray Disc media ho...
