Neuromorphic computing
Neuromorphic computing is an approach to computation modeled on the structure and function of biological nervous systems, combining event-driven spiking communication with co-located memory and processing for greatly reduced energy use.
Neuromorphic computing with nanoscale spintronic oscillators
Neuromorphic computing with nanoscale spintronic oscillators is a brain-inspired hardware approach using spin-torque and spin Hall nano-oscillators as artificial neurons, first demonstrated experimentally in 2017.
Neuromorphic engineering
Neuromorphic engineering, also known as neuromorphics, is the design of computing hardware and methods inspired by neural computation, using event-driven spiking circuits that promise extremely low power consumption.
Neuromorphic photonics
Neuromorphic photonics is a computing field that uses lasers, modulators, and resonators to perform neural-network functions, aiming at high speed and energy efficiency beyond electronic AI accelerators.
Neuroscience in space
Neuroscience in space is the study of how spaceflight environments, chiefly microgravity, radiation, and disrupted day-night cycles, affect the nervous system, producing brain shifts, motion sickness, and altered cognition in astronauts.
Neuschwanstein Castle
Neuschwanstein Castle, or Schloss Neuschwanstein, is a 19th-century historicist palace in Schwangau, Bavaria, begun by King Ludwig II in 1869, never completed, and made a UNESCO World Heritage Site in 2025.
Neutral atom quantum computer
A neutral atom quantum computer, also called a Rydberg quantum computer, stores qubits in uncharged atoms trapped by laser tweezers, entangling them through Rydberg-state interactions.
Neutral Buoyancy Laboratory
The Neutral Buoyancy Laboratory, or Neutral Buoyancy Lab, is a large indoor pool at NASA's Johnson Space Center in Houston where astronauts rehearse spacewalks underwater.
Neutral-point-clamped converter
A neutral-point-clamped (NPC) converter is a multilevel power converter topology, introduced in 1981 by Nabae, Takahashi, and Akagi, that produces three voltage levels per phase and is widely used in medium-voltage drives.
Neutral-point-clamped inverter
The neutral-point-clamped (NPC) inverter is a three-level multilevel inverter introduced by Akira Nabae, Isao Takahashi, and Hirofumi Akagi in 1981, now widely used in medium-voltage motor drives and grid-connected photovoltaic systems.
Neutrality of the Panama Canal
The neutrality of the Panama Canal is a treaty-based regime keeping the Canal open to vessels of all nations equally, established by the 1977 Torrijos–Carter Treaties.
Neutrogena
Neutrogena is an American skincare brand founded in 1930 in Los Angeles around a gentle amber facial soap, built on dermatologist recommendations, and owned by Kenvue since 2023.
Neutron bomb
The neutron bomb, formally an enhanced radiation weapon (ERW), is a low-yield thermonuclear warhead conceived by Samuel T. Cohen in 1958 that kills through neutron radiation rather than blast.
Neutron embrittlement
Neutron embrittlement, also called irradiation embrittlement, is the loss of fracture toughness and ductility caused by neutron radiation, a key aging mechanism of reactor pressure vessels.
Neutron flux
Neutron flux is defined as the number of neutrons crossing a unit area per time. This quantity is the central element in reactor physics linking population to reaction rates.
Neutron generator
A neutron generator is a small accelerator that produces neutrons by fusing hydrogen isotopes, used in oil well logging, elemental analysis, security screening, and nuclear weapons.
Neutron initiator
A neutron initiator is a device that emits a burst of neutrons to start the fission chain reaction in a nuclear weapon, timed to when the core is most compressed.
Neutron logging
Neutron logging is a borehole geophysical method that lowers a neutron source into a well and measures neutrons or gamma rays to estimate porosity, hydrogen content, and fluid saturation.
Neutron tomography
Neutron tomography is an imaging method that reconstructs an object's 3D internal structure from neutron transmission measurements, highlighting light elements like hydrogen inside thick metal parts.
Neutron transport theory
Neutron transport theory is the branch of nuclear science that describes how neutrons move through matter, centered on the Boltzmann transport equation and nuclear reactor analysis.
Nevada Department of Transportation
The Nevada Department of Transportation (NDOT) is the state agency responsible for planning, building, operating, and maintaining Nevada's state highway system, about 5,400 miles with more than 1,200 bridges.
Nevada Institute for Autonomous Systems
The Nevada Institute for Autonomous Systems (NIAS) is a Nevada non-profit that managed the state's FAA-designated drone test site and grew its unmanned aircraft industry.
Nevada State Route 375
Nevada State Route 375, the Extraterrestrial Highway, is a 98-mile highway in south-central Nevada, named in 1996 for its UFO sightings and proximity to Area 51.
Nevada Test Site
The Nevada Test Site, renamed the Nevada National Security Site in 2010, is a Department of Energy installation in southern Nevada that hosted 928 nuclear tests from 1951 to 1992.
Nevada-class battleship
The Nevada class was a pair of US Navy battleships, USS Nevada and USS Oklahoma, completed in 1916 and pioneers of the all-or-nothing armor scheme.
Neville G. W. Cook
Neville G. W. Cook (1938–1998) was a South African-born rock mechanics engineer who held a chair at UC Berkeley and pioneered research on rockbursts and mine safety.
