Microfluidic synthesis
Microfluidic synthesis performs chemical reactions and produces nanoscale materials inside micrometer-scale channels, where fast, precise mixing controls the size of products like quantum dots and lipid nanoparticles.
MicroFUN
MicroFUN, the Microlensing Follow-Up Network, is a consortium of observers coordinated from Ohio State University that detects extrasolar planets by photometric monitoring of microlensing events in the Galactic Bulge.
Microgel
A microgel is a cross-linked polymer colloid particle, typically 10 to 1000 nm, that swells in response to triggers such as pH and temperature, with uses in drug delivery and 3D printing.
Microgels as model soft colloids
Microgels are submicrometer-sized hydrogel particles, covalently crosslinked polymer networks swollen by solvent, whose tunable size and softness make them model systems for soft-sphere colloid physics.
Microkinetic analysis
Microkinetic analysis is a modeling method in catalysis that describes a reaction as a network of elementary steps, predicting rates, mechanisms, surface coverages, and guiding catalyst design.
Microkinetic modeling
Microkinetic modeling is a chemical kinetics method that describes a catalytic reaction as an explicit network of elementary steps with rate constants, predicting turnover frequencies, surface coverages, and selectivities.
Micromagnetic simulation
Micromagnetic simulation is a numerical method that solves the Landau–Lifshitz–Gilbert equation to compute how magnetization evolves in ferromagnetic materials, resolving features such as domain walls and vortices.
Micromagnetics
Micromagnetics is a continuum theory of ferromagnetic materials that treats atomic spins as a continuous magnetization field, valid on scales from about 1 nm to 1 µm.
Micromegas (detector)
Micromegas (MICRO-MEsh GAseous Structure) is a micro-pattern gaseous particle detector invented in 1995 by Ioannis Giomataris and collaborators at Saclay, offering fine spatial resolution and high rate capability.
Micrometre
The micrometre (µm), formerly the micron, is an SI unit of length equal to one millionth of a meter, the natural unit for cells, airborne particles, and light wavelengths.
Micromort
A micromort is a unit of risk equal to a one-in-a-million chance of death, coined by Stanford decision analyst Ronald A. Howard in 1980 for comparing risky activities.
Micron (unit)
The micron is a non-SI name for the micrometre, a unit of length equal to one millionth of a meter, retired by the SI in 1967 but still widely used in filtration and textiles.
Micronova
A micronova is a localized thermonuclear explosion on a white dwarf's surface, roughly a million times weaker than a nova and lasting only hours, first reported in 2022.
Microphone
A microphone is a transducer that converts sound pressure waves into electrical signals, used in recording, telephones, hearing aids, and voice assistants since Edison's 1877 carbon transmitter.
Microphysics scheme
A microphysics scheme is a parameterization in atmospheric and climate models that computes cloud and precipitation processes, such as condensation and particle growth, at subgrid scales.
Micropipette
A micropipette is a hand-held piston-operated instrument that measures and transfers liquid volumes from about 0.1 µL to 1000 µL, standard in chemistry, biology, and clinical laboratories.
Microplate
A microplate is a small, relatively rigid block of lithosphere that moves independently of the major tectonic plates, with oceanic examples like the Easter microplate.
Microplate reader
A microplate reader, also called a plate reader, is a laboratory instrument that detects biological, chemical, or physical events in microplate wells, quantifying absorbance, fluorescence, luminescence, and turbidimetry in one run.
Microquasar
A microquasar is a binary star system with a black hole or neutron star that accretes matter and ejects it in relativistic jets, like a miniature quasar.
Microradiography
Microradiography is an X-ray imaging technique producing magnified images of small specimens, used to reveal microstructure and measure mineral content in bone and dental tissue.
Microreactor
A microreactor is either a miniaturized chemical reactor with micron-scale channels carrying out continuous-flow reactions or a very small nuclear reactor built and transported as a unit.
Microresonator frequency comb
A microresonator frequency comb, also called a Kerr comb or microcomb, is an optical frequency comb generated on a chip by a single continuous-wave laser.
Microrheology
Microrheology is a family of soft matter techniques that measures viscoelastic properties by tracking microscopic probe particles, needing only microliter samples and reaching megahertz frequencies.
MICROSCOPE
MICROSCOPE was a French CNES microsatellite launched on 25 April 2016 to test the equivalence principle in orbit, comparing the free fall of titanium and platinum test masses.
Microscope slide
A microscope slide is a thin, flat rectangle of glass on which a specimen is mounted for examination under a microscope, usually covered with a thin coverslip.
Microscopic reversibility
Microscopic reversibility is the chemical principle that, at equilibrium, a reaction and its reverse proceed at the same rate through the same mechanism, stated by Tolman in 1924.
Microscopy with ultraviolet surface excitation
Microscopy with ultraviolet surface excitation (MUSE) is a slide-free microscopy technique introduced in 2017 that uses shallowly penetrating ultraviolet light to image unsectioned tissue, producing histology-like images within minutes.
Microscopy, Fluorescence, Multiphoton
Multiphoton fluorescence microscopy (two-photon microscopy, multiphoton excitation microscopy) excites fluorophores by simultaneous absorption of pulsed near-infrared photons, giving pinhole-free optical sectioning, deep tissue imaging, and reduced out-of-focus photobleaching.
Microsecond
A microsecond (µs, from the SI prefix micro) is one millionth of a second, the unit in which 1 MHz signals cycle, GPS-disciplined clocks synchronize, and NAND flash memory responds.
Microseismic monitoring
Microseismic monitoring is a passive geophysics method that records very small earthquakes from hydraulic fracturing and fluid flow, used to image subsurface fractures and stress changes.
