Plating

Plating, also called metal plating, is the deposition of a thin metallic layer onto a surface, most often by electroplating, for corrosion protection, wear resistance, or decoration.

Platinum

Platinum is a chemical element with symbol Pt and atomic number 78, a dense, silvery-white metal best known for catalytic converters, jewelry, and the cancer drug cisplatin.

Platinum (Miranda Lambert album)

Platinum is Miranda Lambert's fifth studio album, a 16-track 2014 RCA Nashville release named for her hair color and a title-track song. Guests include Carrie Underwood, Little Big Town, and the Time Jumpers; critics were largely positive.

Platinum dichalcogenides

Platinum dichalcogenides are layered compounds of platinum with sulfur, selenium, or tellurium, two-dimensional materials whose electronic properties change with thickness, used for photodetectors and catalysis.

Platinum dioxide

Platinum dioxide (PtO₂), also called platinum(IV) oxide or platinic oxide, is a dark brown solid best known as Adams' catalyst, used since 1922 to hydrogenate alkenes, ketones, and arenes.

Platinum diselenide

Platinum diselenide (PtSe₂) is a layered transition metal dichalcogenide of platinum and selenium, changing from semimetal to semiconductor when thinned to a few atomic layers.

Platinum dissolution and platinum band formation in fuel cells

Platinum dissolution in fuel cells is the electrochemical loss of platinum from a PEMFC cathode, a degradation pathway where dissolved ions form a platinum band in the membrane.

Platinum End (プラチナエンド)

Platinum End (プラチナエンド) is a supernatural manga by Death Note creators Tsugumi Ohba and Takeshi Obata, serialized in Jump SQ. 2015–2021 in 14 volumes, about 13 God candidates including Mirai Kakehashi competing within 999 days; adapted as a 24-episode 2021–2022 anime.

Platinum Jubilee of Elizabeth II

The Platinum Jubilee of Elizabeth II (2022) marked 70 years since her 6 February 1952 accession, the first Platinum Jubilee of a British monarch, celebrated over a four-day June weekend with Trooping the Colour, a St Paul's thanksgiving service, and the Platinum Pageant.

Platinum manganese

Platinum manganese (PtMn, also written MnPt) is an antiferromagnetic platinum-manganese alloy whose L1₀ phase, stable to about 975 K, pins MRAM reference layers and generates spin-orbit torques for spintronic devices.

Platinum print

Platinum print (platinotype): monochrome photographic print in platinum metal within paper fibers, patented by William Willis in 1873, commercial from 1879; prized for tonal range and matte surface, declined in World War I, revived since the 1970s.

Platinum-cobalt alloy catalyst

A platinum-cobalt alloy catalyst is a carbon-supported nanoparticle electrocatalyst used in fuel cell cathodes, which reduces oxygen faster than pure platinum while using less of it.

Platinum-ruthenium anode catalyst

A platinum-ruthenium anode catalyst, or PtRu, is a bimetallic electrocatalyst, usually alloy nanoparticles on carbon, used in direct methanol fuel cells for its carbon monoxide tolerance.

Platinum(IV) prodrug

A platinum(IV) prodrug is an inert, six-coordinate platinum(IV) complex that is reduced inside cells to release an active platinum(II) anticancer drug such as cisplatin, satraplatin being the best-known candidate.
