Plasmonic nanorulers
Made of metallic nanostructures like gold, plasmonic nanorulers measure nanoscale separations and calibrate microscopes by utilizing coupled plasmon resonance that shifts with the distance between structures.
Plasmonic picocavity
Plasmonic picocavities are optical cavities smaller than a nanometer, formed by single-atom adatom defects on metallic nanostructures, identified in 2016, enabling single-molecule spectroscopy.
Plasmonic tweezers
Plasmonic nanotweezers, also called plasmonic optical tweezers, are optical trapping devices that use surface plasmons in metallic nanostructures to trap nanoparticles at low laser power.
Plasmonic waveguide
A plasmonic waveguide guides light as a surface plasmon polariton at a metal–dielectric interface, achieving subwavelength confinement beyond the diffraction limit but limited by metal loss.
Plasmopara viticola
Plasmopara viticola is an oomycete water mold that causes downy mildew of grapevines. Endemic to North American Vitis, it reached Europe around 1871 and spread into a devastating pandemic.
Plassey Plot
The Plassey Plot (পলাশীর ষড়যন্ত্র) was the 1757 secret arrangement by which the British East India Company and Mir Jafar overthrew Nawab Siraj-ud-Daulah of Bengal.
Plast
Plast (Пласт), formally the Plast National Scout Organization of Ukraine, is a scouting organization founded in Lviv in 1911, banned in Soviet Ukraine in 1924, and re-established there in 1991.
Plaster
Plaster, also known as calcined gypsum, is a building material made from lime, gypsum, or cement mixed with water and applied wet to walls and ceilings, hardening in place.
Plastered human skulls
Plastered human skulls are Neolithic Levant skulls, about 8000 to 6000 BC, whose faces were remodelled in plaster, often with shells in the eye sockets.
Plastic
Plastic is a polymeric material, often blended with additives, that can be shaped by flow into finished products; global production reached 460 million tonnes in 2019, with only 9% of waste recycled.
Plastic analysis (structural engineering)
Plastic analysis is a structural engineering method that determines a structure's true collapse load by following its behavior past first yield, through plastic hinge formation, until it becomes a mechanism.
Plastic and reconstructive surgery
Plastic and Reconstructive Surgery (PRS) is the monthly peer-reviewed official journal of the American Society of Plastic Surgeons, published by Lippincott Williams & Wilkins since 1946, with open-access companion PRS Global Open (2013).
Plastic bag
A plastic bag, or polybag, is a flexible container made of plastic film, usually polyethylene, invented in 1959 by Swedish engineer Sten Gustaf Thulin for Celloplast.
Plastic baton round
The plastic baton round, officially the baton round and popularly the plastic bullet, is a less-lethal 37 mm projectile developed for the British Army and police in Northern Ireland during the Troubles.
Plastic Beach
Plastic Beach is the third studio album by virtual band Gorillaz, released March 9, 2010 on Virgin. An environmental concept album about plastic pollution, it debuted at No. 2 in the US and UK and scored 77 on Metacritic.
Plastic Bertrand
Plastic Bertrand, stage persona of Roger François Jouret (born 1954, Brussels), Belgian new wave singer whose 1977 hit "Ça plane pour moi" sold millions; producer Lou Deprijck sang the original recording.
Plastic bottle
Plastic bottle: molded polymer container, chiefly PET, patented by Nathaniel Wyeth in 1973 and made by injection stretch blow molding. Dominant beverage packaging; recycling outcomes vary from 9% globally to over 85% in Japan.
Plastic bronchitis
Plastic bronchitis (PB), also called cast bronchitis or Hoffman bronchitis, is a rare disorder in which branching bronchial casts obstruct airways. Subtypes are lymphatic (post-Fontan) and eosinophilic; treatment includes lymphatic embolization.
Plastic crystal electrolytes
Plastic crystal electrolytes (PCEs) are solid-state electrolytes combining a metal salt with a plastic crystal, a solid whose molecules rotate, giving solid materials with liquid-like ion transport for batteries.
Plastic degradation
Plastic degradation is the partial or complete breakdown of a polymer by physical, chemical, or biological reactions, causing discoloration, surface cracking, and fragmentation, and underpinning both plastic litter persistence and chemical recycling.
Plastic embedding
Plastic embedding is a histology sample-preparation method in which fixed tissue is infiltrated with a polymerizable resin instead of paraffin wax, yielding blocks that can be sectioned far thinner for light and electron microscopy.
Plastic explosive
Plastic explosive, also called plastique or putty explosive, is a hand-moldable high explosive such as C-4 or Semtex, developed during World War II and subject to a 1991 detection-marking treaty.
Plastic Hearts
Plastic Hearts is Miley Cyrus's seventh studio album, released November 27, 2020 via RCA Records; a rock and glam rock record with Billy Idol, Dua Lipa, Joan Jett, and Stevie Nicks, peaking at number 2 on the Billboard 200 and number 1 on Top Rock Albums.
Plastic hinge
A plastic hinge is a localized yielding zone in a structural member that rotates like a hinge at constant moment, underlying plastic analysis of steel and concrete frames.
Plastic hydrocracking
Plastic hydrocracking is a chemical recycling method that cleaves carbon–carbon bonds in plastic polymers with hydrogen over bifunctional catalysts, converting polyolefin waste into fuels and lubricants.
Plastic hydrogenolysis
Plastic hydrogenolysis is a chemical recycling method in which transition-metal catalysts and hydrogen cleave the carbon–carbon bonds of waste polymers, mainly polyolefins, turning them into fuels, lubricants, and waxes.
Plastic ice
Plastic ice is a high-pressure crystalline phase of water in which molecules stay fixed on the lattice but rotate, predicted in 2009 and first observed in 2025.
Plastic ice VII
Plastic ice VII is a high-pressure phase of water in which water molecules rotate as fast as in liquid water while holding a solid crystal lattice, predicted in 2008 and first observed in 2025.
Plastic Letters
Plastic Letters is Blondie's second studio album (February 1978, Chrysalis), produced by Richard Gottehrer; singles "Denis" (UK No. 2) and "Presence, Dear" (UK No. 10) broke the band in Europe.
Plastic Man
Plastic Man, Patrick "Eel" O'Brian, is DC's elastic shapeshifting superhero created by Jack Cole, debuting in Quality Comics' Police Comics #1 (August 1941); acquired by DC in 1956, revived by Kyle Baker and others, with a film in development since 2018.
