The Brigadier orders all his troops to be fitted with a depolariser on the back of the neck.

A depolarizer or depolariser is an optical device used to scramble the polarization of light.

In the Poggendorff cell, the electrolyte was dilute sulphuric acid and the depolariser was chromic acid.

The German scientist Johann Christian Poggendorff overcame the problems with separating the electrolyte and the depolariser using a porous earthenware pot.

UNIT frees Watkins from IE, while the Doctor perfects his depolariser, which protects the wearer against the Cyber control signal.

The remaining space between the electrolyte and carbon cathode is taken up by a second paste consisting of ammonium chloride and manganese dioxide, the latter acting as a depolariser.

A depolarizer or depolariser, in electrochemistry, according to an IUPAC definition, is a synonym of electroactive substance, i.e., a substance which changes its oxidation state, or partakes in a formation or breaking of chemical bonds, in a charge-transfer step of an electrochemical reaction.

This depolarizer also has a preferred orientation because of its single defined fast axis.

The Cornu depolarizer is also named after him.

Manganese dioxide is, therefore, the most widely used depolarizer.

The whole device is much more compact than a Cornu depolarizer (for the same aperture).

A depolarizer or depolariser is an optical device used to scramble the polarization of light.

The fast axes are 90 degrees apart and 45 degrees from the sides of the depolarizer (see figure).

The Lyot depolarizer is another early design.

The output is periodic across the depolarizer.

The depolarizer is a paste of mercurous sulfate.

A battery depolarizer takes up electrons during discharge of the cell; therefore, it is always an oxidizing agent.

Because the wedge angle is so much smaller than in a Cornu depolarizer the period is larger, often around 6 mm.

The electrolyte and depolarizer were mixed.

Depolarization or depolarizer may refer to:

The Chromic acid cell was a type of primary cell which used chromic acid as a depolarizer.

The term "depolarizer" can be considered as outdated or misleading, since it is based on the concept of "polarization" which is hardly realistic in many cases.

An ideal depolarizer would output randomly polarized light whatever its input, but all practical depolarizers produce pseudo-random output polarization.

The Cornu depolarizer was one of the earliest designs, named after its inventor Marie Alfred Cornu.

In the battery industry, the term "depolarizer" has been used to denote a substance used in a primary cell to prevent buildup of hydrogen gas bubbles.

The letter L indicates the electrochemical system used; a zinc negative electrode, manganese dioxide depolarizer and positive electrode, and an alkaline electrolyte.

Other significant applications of mercuric chloride include its use as a depolarizer in batteries and as a reagent in organic synthesis and analytical chemistry (see below).

In Leclanché's original cell the depolarizer, which consisted of crushed manganese dioxide, was packed into a pot, and a carbon rod was inserted to act as the cathode.

Zinc-air batteries use air as the depolarizer and have much higher capacity than other types (they use air from the atmosphere which does not need to be supplied in the battery).

The invention of the Leclanché cell in 1866 and the subsequent improvement of the batteries containing manganese dioxide as cathodic depolarizer increased the demand of manganese dioxide.

Because each half of the optic is a wedge, and the two halves do not have exactly the same refractive index (for a particular polarization), the depolarizer is effectively very slightly wedged (optically).

Special considerations are needed when this depolarizer is to be used for a particular application, because the optimal wave-plate thicknesses depend on the signal wavelength and optical spectrum with which it is to be used.
