Potassium metal anode
A potassium metal anode is the metallic potassium negative electrode in potassium metal batteries, offering 687 mAh g⁻¹ capacity, a low potential of −2.93 V, and low cost.
Potassium niobate
Potassium niobate (KNbO3, often abbreviated KN) is a perovskite-structure ferroelectric oxide whose strong piezoelectric and optical properties make it a candidate for lead-free piezoceramics and photonic devices.
Potassium sodium niobate
Potassium sodium niobate (KNN) is a lead-free perovskite piezoelectric ceramic, a solid solution of potassium niobate and sodium niobate and the most researched lead-free alternative to PZT.
Potassium-ion battery
A potassium-ion battery is a rechargeable battery in which potassium ions move between cathode and graphite anode; it is a low-cost lithium-ion alternative for grid storage, still in development.
Potential induced degradation
Potential induced degradation (PID) is a loss of photovoltaic module power caused by leakage currents that move sodium ions from the glass into the solar cells.
Potential method
The potential method, also known as the physicist's method, is a technique of amortized analysis in which a potential function measures stored work in a data structure.
Potential test (petroleum)
A potential test is a well testing procedure in petroleum engineering that estimates the theoretical absolute open flow (AOF) rate at zero sandface backpressure, used for reservoir assessment and production allocation.
Potentiometer
A potentiometer, commonly abbreviated pot, is a three-terminal resistive component with a movable wiper on a resistive track, acting as an adjustable voltage divider used for volume controls and calibration.
Pothole
A pothole is a bowl-shaped hole in a road pavement that grows under traffic and weather, a leading source of vehicle damage costing US motorists almost $3 billion a year.
Pothole patching
Pothole patching is the localized repair of broken-out road areas, replacing failed pavement with asphalt or another compound; methods include throw-and-roll, spray injection, and infrared patching.
Potochnoye Oil Field
Potochnoye Oil Field (Поточное месторождение) is a large oil field in the Khanty-Mansi Autonomous Okrug, Western Siberia, discovered in 1974 and operated by LUKOIL-Western Siberia.
Potomac Edison
The Potomac Edison Company is an investor-owned electric utility headquartered in Williamsport, Maryland, serving about 295,000 customers in western Maryland and 155,000 in West Virginia's Eastern Panhandle as a subsidiary of FirstEnergy.
Potomac Electric Power Company
The Potomac Electric Power Company (Pepco) is an electric utility serving Washington, D.C., and Montgomery and Prince George's counties in Maryland, incorporated in 1896 and owned by Exelon.
Potters Bar rail accidents
The Potters Bar rail accidents, known as the Potters Bar crash, were railway accidents at Potters Bar station in Hertfordshire, England, including a deadly 1946 collision and 2002 derailment.
Pottery
Pottery is ware made from shaped clay that is dried and fired in a kiln, permanently hardening the clay; it also names the craft of making such ware.
Potting (electronics)
Potting is an electronics manufacturing method that encases a component in a liquid resin, such as epoxy or silicone, cured to protect it from moisture and vibration.
Pouce Coupe Oil and Gas Field
The Pouce Coupe oil and gas field is a producing field on the Alberta–British Columbia border near Grande Prairie, first drilled for gas in 1920 and now a major Montney tight gas play.
Pouce Coupe South Oil and Gas Field
Pouce Coupe South is an oil and gas field in northwestern Alberta, just east of the British Columbia border, and one of Canada's most active Montney play locations.
Pouch bag
A pouch bag is a soft, unstructured handbag, typically closed by a drawstring, known for Bottega Veneta's oversized 2019 Pouch and a runway revival for spring 2026.
Pouch cell
A pouch cell is a lithium-ion battery cell sealed in a flexible aluminum-polymer pouch instead of a rigid metal can, offering low weight and custom sizes.
Poudre B
Poudre B was the first practical smokeless military propellant, a nitrocellulose powder invented in 1884 by French chemist Paul Vieille, which armed the Lebel rifle of 1886 and remained France's main powder until World War II.
Poulaphouca Reservoir
Poulaphouca Reservoir, locally called the Blessington Lakes, is an artificial lake in Counties Wicklow and Kildare, Ireland, created by damming the River Liffey in 1940.
Pounding (structural engineering)
Pounding, also called seismic pounding, is the collision of adjacent buildings during earthquake shaking when the separation gap between them is too small, causing damage or collapse.
Povkhovskoye Oil Field
The Povkhovskoye Oil Field (Повховское) is a large, mature onshore oil field near Kogalym in Western Siberia, Russia, discovered in 1972 and operated by LUKOIL subsidiary TPP Povkhneftegaz.
Povl Ole Fanger
Povl Ole Fanger (1934–2006) was a Danish scientist at the Technical University of Denmark known for the PMV thermal comfort model and the olf and decipol units.
Powder coating
Powder coating is a finishing process in which dry polymer powder is applied electrostatically and heated to melt into a protective, decorative film that releases almost no VOCs.
Powder injection molding
Powder injection molding (PIM) is a manufacturing process that mixes fine metal or ceramic powder with a polymer binder, injection molds the feedstock, and sinters the part to near-full density.
Powder metallurgy
Powder metallurgy, or powdered metal (PM), is a metal-forming process in which metal powders are pressed into a die and sintered just below their melting point into solid parts.
Powdered activated carbon
Powdered activated carbon (PAC) is activated carbon in fine particles, typically 10 to 100 micrometers, dosed into water and wastewater to remove dissolved organic contaminants, tastes, and odors.
