Nanoscale nuclear magnetic resonance
Nanoscale nuclear magnetic resonance (nano-NMR) is NMR spectroscopy and imaging on nanometer-to-micrometer samples, using magnetic resonance force microscopy and nitrogen-vacancy centers in diamond as sensors.
Nanosecond
A nanosecond (ns) is a unit of time equal to one billionth of a second, the timescale of fast electronics; light travels about 1 foot in it.
Nanospray desorption electrospray ionization
Nanospray desorption electrospray ionization (nano-DESI) is an ambient mass spectrometry method reported in 2010, in which a solvent bridge between two capillaries dissolves analytes from a surface for imaging.
Nanostructured thermoelectrics
Nanostructured thermoelectrics are thermoelectric materials given nanoscale features such as grains, precipitates, and superlattices to scatter phonons, raise the figure of merit ZT, and improve waste heat recovery.
Nanothermometry
Nanothermometry is the measurement of temperature with nanoscale spatial resolution, reading temperature-dependent optical or electrical signals from nanoscale probes such as luminescent nanoparticles in cells, tissue, and devices.
Nanotwinned diamond
Nanotwinned diamond is a synthetic polycrystalline diamond with twin boundaries a few nanometers apart, reported in 2014 to be harder than natural diamond and more heat resistant.
Nanotwinned materials
Nanotwinned materials are crystalline materials, most often face-centered cubic metals, containing nanoscale twins below 100 nm spacing that strengthen like grain boundaries while preserving ductility, with uses in microelectronics.
Nanowire
A nanowire is a solid crystalline filament, typically 10 to 100 nanometres in diameter, whose quantum confinement and high surface-to-volume ratio enable sensors, solar cells, thermoelectrics, and quantum electronics.
Nanowire laser
A nanowire laser is a nanoscale semiconductor laser in which a single nanowire serves as both gain medium and optical resonator, demonstrated from ultraviolet to mid-infrared wavelengths.
Nanowire plasmonic laser
A nanowire plasmonic laser is a nanoscale semiconductor laser in which a semiconductor nanowire provides gain and a metal-insulator waveguide confines light below the diffraction limit.

Naolinco Volcanic Field
Naolinco Volcanic Field (Naolinca de Victoria Volcanic Field), a Quaternary monogenetic volcanic field of pyroclastic cones and basaltic flows in the Sierra de Chiconquiaco, Veracruz, Mexico; last erupted about 1145 CE from El Volcancillo, whose Río Naolinco pāhoehoe flow ran 50 km.
Naomi J. Halas
Naomi J. Halas, also known as Naomi Halas, is an American scientist and engineer at Rice University who pioneered plasmonics and invented the tunable plasmon and nanoshell nanoparticles.
Naoto Chatani
Naoto Chatani (茶谷 直人) is a Japanese organic chemist known for transition-metal-catalyzed activation of unreactive bonds, especially C–H bonds, and has been Vice President of Hiroshima University since 2024.

Naphtalene
Naphtalene (naphthalene, C10H8, CAS 91-20-3) is the simplest polycyclic aromatic hydrocarbon, a mothball-scented white solid made from coal tar and petroleum and used mainly to make phthalic anhydride.
Naphthalene
Naphthalene, also known as tar camphor or white tar, is a white crystalline aromatic hydrocarbon from coal tar, best known as the active ingredient of mothballs.
Naphthalenediamines
Naphthalenediamines, also called naphthylenediamines, are aromatic amines with formula C₁₀H₁₀N₂ bearing two amino groups on the naphthalene ring; the 1,5-isomer makes dyes and polyurethane elastomers, while the 1,8-isomer anchors perimidines and proton sponges.
Naphthalenetetracarboxylic dianhydride
Naphthalenetetracarboxylic dianhydride (NTCDA) is a planar aromatic compound, formula C14H4O6, best known as the 1,4,5,8-isomer, used as a polyimide monomer and n-type organic semiconductor in thin-film electronics.
Naphthalimide
Naphthalimide is a bicyclic organic compound of formula C12H7NO2, a naphthalene ring system fused to an imide at the 1,8 positions, whose derivatives are widely used fluorescent dyes and probes.
Napier Shaw
Napier Shaw, or Sir William Napier Shaw, was a British meteorologist who directed the UK Meteorological Office from 1905 to 1920, introduced the millibar, and devised the tephigram.
Napier's bones
Napier's bones, also called Napier's rods, are numbered calculating rods described by Scottish mathematician John Napier in 1617, designed to reduce multiplication and division to simple addition.
Nappe
A nappe is a large, sheet-like body of rock that has moved far from its original position by thrust faulting or recumbent folding, a structure typical of mountain ranges.
Napping (sensory evaluation)
Napping is a sensory evaluation method in which assessors arrange product samples on a sheet, so that closer placement means perceived similarity, yielding a product map.
