Metal Health
Metal Health (1983) is Quiet Riot's third album, produced by Spencer Proffer at Pasha Music House, Hollywood. First heavy metal album to top the Billboard 200, displacing Synchronicity; sold about 5.5 million copies.
Metal homeostasis regulation and metal sensing
Metal homeostasis regulation and metal sensing is how cells detect trace-metal ions such as iron, zinc, and copper and switch import, efflux, and storage pathways on or off.
Metal hydride compressor
A metal hydride compressor is a thermally driven device that compresses hydrogen by absorbing it into a metal alloy at low temperature, then heating it to release high-pressure hydrogen.
Metal hydride thermal energy storage
Metal hydride thermal energy storage is a thermochemical method that stores heat through reversible hydrogen absorption in metal hydrides, offering high storage density for solar plants and waste heat.
Metal Injection
Metal Injection is an American heavy metal news and video media platform, launched online in 2004 by co-founders Frank Godla and Robert Pasbani and operated by Sony Music's The Orchard since 2022.
Metal injection molding
Metal injection molding (MIM) is a powder metallurgy process that mixes fine metal powder with a thermoplastic binder, molds it like plastic, and sinters it to near-full density.
Metal lathe
A metal lathe, also called an engine lathe or center lathe, is a machine tool that rotates a workpiece against a stationary cutting tool to make round parts.
Metal Machine Music
Metal Machine Music: Lou Reed's 1975 RCA double album of pure guitar feedback, 64 minutes with no songs or vocals, initially panned and withdrawn, later a noise-music touchstone.
Metal matrix composite
A metal matrix composite (MMC) is an engineered material combining a metal matrix, usually aluminum, titanium, or magnesium, with ceramic reinforcement for strength, stiffness, and wear resistance.
Metal oxide redox thermal energy storage
Metal oxide redox thermal energy storage is a thermochemical technology that stores heat in the reversible reduction of a metal oxide and releases it on reoxidation with air.
Metal particle tape
Metal particle tape (MP tape) is a magnetic recording tape whose coating is pure iron particles in a polymer binder, introduced for videotape in 1987 and used in Betacam SP, 8 mm, and D-2.
Metal peroxides
Metal peroxides are metal compounds containing a peroxide unit, O2^2−, bound either as a discrete ion or as a peroxo or hydroperoxo ligand at a metal center.
Metal Slug (メタルスラッグ)
Metal Slug (メタルスラッグ) is SNK's run-and-gun franchise debuting April 1996 on Neo Geo, developed by Nazca; Marco and Tarma fight General Morden. Known for pixel art, the tank, and a 2026 30th-anniversary reboot.
Metal Slug Tactics
Metal Slug Tactics is a turn-based tactical RPG with roguelite elements by Leikir Studio, published by Dotemu and Gamirror Games, released November 5, 2024.
Metal-bound Coffer (Jin Teng)
The Metal-bound Coffer (金縢) is a chapter of the Book of Documents recounting how Zhou Gong offered his life in place of the ill King Wu, and was later vindicated by King Cheng.
Metal-clad switchgear
Metal-clad switchgear (MC switchgear) is medium-voltage switchgear in which circuit breakers, buses, and cable terminations are housed in separate compartments enclosed by grounded metal barriers.
Metal-dependent aminopeptidase
Metal-dependent aminopeptidases are exopeptidase enzymes that remove amino acids one at a time from peptide N-terminus, using one or two bound metal ions, most often zinc, to catalyze hydrolysis.
Metal-enclosed switchgear
Metal-enclosed switchgear is power switching equipment enclosed on all sides and top in sheet metal, containing switches, circuit breakers, fuses, and buses for medium-voltage distribution, standardized by IEEE C37.20.3.
Metal-free electrocatalysis
Metal-free electrocatalysis is the acceleration of electrochemical reactions at electrodes made without metal atoms, usually carbon materials, begun in 2009 as an alternative to platinum catalysts.
Metal-free room-temperature phosphorescence
Metal-free room-temperature phosphorescence (metal-free RTP) is long-lived phosphorescence from purely organic materials at ambient temperature, achieved without heavy metals through rigidifying molecular design, with applications in OLEDs, anti-counterfeiting, and bioimaging.
Metal-halide lamp
A metal-halide lamp is a high-intensity discharge lamp that makes light from an electric arc through mercury vapor and metal-halide salts, first announced commercially by General Electric in 1962.
Metal-hydride hydrogen atom transfer
Metal-hydride hydrogen atom transfer (MHAT) is a catalytic method in organic synthesis in which a transition-metal hydride transfers a hydrogen atom to an alkene, generating a carbon radical.
Metal-independent carbonic anhydrase domain
The metal-independent carbonic anhydrase domain (IPR060395) is a protein domain defining iota-class carbonic anhydrases, NTF2-like-fold enzymes that catalyze carbon dioxide hydration; some are metal-independent, while others reportedly contain metal ions.
Metal-metal bond
A metal–metal bond is a direct bond between two metal atoms in a compound, with bond orders up to quintuple and distances as short as 1.73 Å.
Metal-organic capsules for drug delivery
Metal-organic capsules for drug delivery are nanoscale containers built from metal-organic framework chemistry that hold drugs and release them at disease sites in response to acidity, glutathione, or enzymes.
Metal-organic chemical vapor deposition
Metal-organic chemical vapor deposition, also called metalorganic vapor phase epitaxy (MOVPE), is an epitaxy process that grows semiconductor films and dominates manufacture of LEDs and laser diodes.
Metal-organic decomposition
Metal-organic decomposition (MOD) is a nonvacuum, liquid-based thin-film method that converts spin-coated metal-organic precursor solutions into metal, oxide, or other compound films by pyrolysis, used for superconductors and printed metal inks.
Metal-organic framework electrocatalysts
Metal-organic framework electrocatalysts are catalysts for electrode reactions such as carbon dioxide reduction, built from metal ions or clusters linked by organic ligands, with tunable structures and high porosity.
