PM M1910
The PM M1910 is a Russian water-cooled heavy machine gun adopted in 1910, the standard machine gun of Russian and Soviet forces through both world wars.
PM3-CAA Oil and Gas Field
The PM3-CAA Oil and Gas Field, or PM3 Commercial Arrangement Area, is a producing oil and gas block jointly developed by Malaysia and Vietnam in the Gulf of Thailand.
PM6:Y6 bulk heterojunction
PM6:Y6 is the bulk heterojunction active layer formed by blending the donor polymer PM6 with the non-fullerene acceptor Y6, setting a certified 14.9% efficiency record in 2019.
PMD (software)
PMD, short for Programming Mistake Detector, is an open-source static code analyzer for Java and Apex that finds flaws like unused variables and empty catch blocks.
PMI (company)
PMI (银泰科技), also known as Precision Motion Industries, is a Taiwanese manufacturer of ballscrews, linear guideways, and actuators, founded in 1990 and headquartered in Taichung, serving machine tools and semiconductor equipment.
PMMA resist
PMMA resist is poly(methyl methacrylate) dissolved in a solvent such as anisole, a positive-tone electron-beam resist in which exposure breaks the polymer backbone so exposed areas dissolve away.
PMN mine
The PMN mine, also designated PMN-1, is a Soviet pressure-actuated blast anti-personnel mine first fielded in the 1950s with a plastic body and 0.2 kg TNT charge.
PMN-PT
PMN-PT is a piezoelectric single-crystal solid solution of lead magnesium niobate and lead titanate whose giant piezoelectric coefficients have reshaped high-end ultrasonic transducers since the late 1990s.
PMR446
PMR446 (Private Mobile Radio, 446 MHz) is a European license-free walkie-talkie service created in 1998, limited to 500 mW, with 16 analog and 32 digital channels.
Pneumatic artificial muscles
Pneumatic artificial muscles, or PAMs, are soft actuators mimicking biological muscle by converting pressurized gas into pulling force, best known in the McKibben design invented in 1957.
Pneumatic circuit
A pneumatic circuit is an arrangement of compressed-air components, typically supply preparation, directional control valves, and actuators, connected so pressurized air produces controlled motion or logic signals.
Pneumatic conveying
Pneumatic conveying is a method of moving dry bulk materials such as powders, granules, and pellets through enclosed pipelines using air, common in chemical, food, and cement industries.
Pneumatic conveying system
A pneumatic conveying system transports bulk dry materials like flour, cement, and plastic pellets through an enclosed pipeline using compressed air or suction, in dilute or dense phase.
Pneumatic cylinder
A pneumatic cylinder is an actuator that converts compressed air pressure into linear motion through a piston, widely used in industrial automation since the twentieth century.
Pneumatic pressure test
A pneumatic pressure test verifies the strength or leak-tightness of a vessel or piping system using compressed gas, typically dry air or nitrogen, instead of water.
Pneumatic stepper motor
A pneumatic stepper motor is an actuator that rotates its shaft in discrete steps using compressed air instead of electricity, widely used in MRI-guided surgical robots.
Pneumatic tube
A pneumatic tube, also known as pneumatic post, moves items inside cylindrical carriers through pipes using compressed air, first used for telegrams in 1853 and now mostly used in hospitals.
Pneumatica
Pneumatica (Greek: Πνευματικά), also known as Pneumatics, is a two-book treatise by Hero of Alexandria describing roughly 80 devices worked by compressed air, steam, and water, including the aeolipile.
Pneumatics
Pneumatics is the branch of fluid power in which a gas, almost always compressed air, transmits and controls energy, flowing from compressors through valves to actuators that produce motion.
PneuNet
A PneuNet, or pneumatic network, is a soft pneumatic actuator made of an elastomer with interconnected air chambers that bends when pressurized, widely used in soft grippers.
PNG
PNG, or Portable Network Graphics, is a lossless image file format developed as a patent-free replacement for GIF and approved as a W3C Recommendation in 1996.
PNG LNG
PNG LNG is Papua New Guinea's first and largest liquefied natural gas project, operated by ExxonMobil and exporting from a two-train plant near Port Moresby since 2014.
PNG LNG Pipeline
The PNG LNG Pipeline is a 700-kilometer natural gas pipeline in Papua New Guinea, carrying gas from the Highlands to an LNG plant near Port Moresby since 2014.
PNI Sensor
PNI Sensor Corporation is an American company in Windsor, California, making magneto-inductive magnetometers, compasses, and AHRS modules for defense and commercial uses where GPS fails.
Pnpm
Pnpm is an open-source JavaScript and Node.js package manager, first released in 2016, that saves disk space by storing packages once and linking them into each project.
PNS Ghazi
PNS Ghazi, formerly USS Diablo, was a Tench-class submarine of the Pakistan Navy, the first operated in South Asia, lost with all hands off Visakhapatnam in December 1971.
PNS Hangor (S131)
PNS Hangor (S131) was a Daphné-class submarine of the Pakistan Navy, in service from 1969 to 2006, best known for sinking the Indian frigate INS Khukri in 1971.
Po-Chun Hsu
Po-Chun Hsu is a materials scientist known for textiles that cool the body by radiative heat transfer, and an assistant professor of molecular engineering at the University of Chicago since 2022.
Po‐Yen Chen
Po-Yen Chen is an associate professor of chemical and biomolecular engineering at the University of Maryland who uses machine learning and robotics to discover sustainable materials.
