Microwave-assisted plastic depolymerization
Microwave-assisted plastic depolymerization is a chemical recycling method that uses microwave irradiation to break waste polymers into monomers, often faster and with less energy than conventional heating.
Microwave-assisted pyrolysis
Microwave-assisted pyrolysis is a thermochemical process that heats biomass or waste plastic with microwaves instead of an external furnace, converting it faster and more efficiently into bio-oil, syngas, and biochar.
Microwave-assisted synthesis
Microwave-assisted synthesis, also known as microwave synthesis, is a chemistry method using microwave dielectric heating to drive reactions, cutting times from hours to minutes since its 1986 founding.
Microwave-to-optical conversion
Microwave-to-optical conversion, in its quantum form called microwave-to-optical quantum transduction, is the coherent conversion of photons between microwave and optical frequencies while preserving their quantum state.
Microwave-to-optical transduction
Microwave-to-optical transduction, also called quantum frequency conversion, coherently converts quantum states between microwave and optical photons, linking devices like superconducting quantum processors and quantum memories.

Mid central vowel
Mid central vowel, IPA /ə/, called schwa: a mid-height, central, usually unrounded vowel produced with a neutral vocal tract. Canonical formants near 500 and 1500 Hz; common as a reduced unstressed vowel, notably in English.
Mid loop
Mid loop is a Nikoli logic puzzle: draw one non-crossing loop through a grid so every dot is the exact midpoint of the straight segment through it, with dots on cell centers or borders.
Mid Ulster (UK Parliament constituency)
Mid Ulster is a county constituency in the UK House of Commons covering Northern Ireland around Lough Neagh, held by Cathal Mallaghan of Sinn Féin since 2024.
Mid-air collision
A mid-air collision is an accident in which two or more aircraft collide while both are airborne, most often near an airport when one overtakes another.

Mid-circuit measurement and classical control
Mid-circuit measurement is the operation of measuring qubits while a quantum circuit is still running, producing a classical outcome used to condition later operations, enabling qubit reset and reuse.
Mid-dermal elastolysis
Mid-dermal elastolysis (MDE), also called idiopathic or acquired mid-dermal elastolysis, is a rare acquired skin disease with selective loss of mid-dermal elastic fibers, causing fine wrinkling, perifollicular papules, or reticular erythema mainly in young women.
