Nettle

== Description ==
Generally a name for plants with stinging hairs, but specifically refers to plants from the family Urticaceae. Nettles have been cultivated for centuries in Europe and Asia as a source of fiber for ropes and sails. The best known fibers from th Urtica family are stinging nettle (Urtica dioica), small nettle (Urtica urens), giant nettle (Urtica ardens), and the Roman nettle (Urtica pilulifera). https://cameo.mfa.org/wiki/Category:FRIL:_Stinging_NettleThey are used for twine, rope, canvas and sailcloth. Nettle fibers are also used as substitutes for flax and hemp. 
Ramie (Boehmeria nivea) is also in the nettle family.

Neutron

== Description ==
The neutron is an elementary particle that has the symbol n, no net electric charge and a mass slightly larger than that of a proton. With the exception of hydrogen-1, nuclei of atoms consist of protons and neutrons, which are therefore collectively referred to as nucleons. The number of protons in a nucleus is the atomic number and defines the type of element the atom forms. The number of neutrons is the neutron number and determines the isotope of an element. For example, the abundant carbon-12 isotope has 6 protons and 6 neutrons, whereas the very rare radioactive carbon-14isotope has 6 protons and 8 neutrons
Neutrons are involved in examination or analysis techniques like neutron radiography, autoradiography, neutron activation analysis, neutron diffraction.
== Synonyms and related terms ==
neutron (Deut., Fr.)
== Risks ==
Similarly to X-rays, gamma rays, beta particles, neutrons are dangerous for the human health.

Neutron activation analysis

== Description ==
An analytical technique used to qualitatively or quantitatively determine the elemental content of materials. Neutron activation analysis (NAA) uses a neutron source, such as a reactor or an accelerator, to irradiate the sample. Elements in the sample become radioactive and emit gamma rays as they decay. The characteristic energy lines and intensity of the decay processes are measured with a detector and a gamma spectrometer to determine the types and amounts of elements present. NAA is good for trace elemental analysis since detection limits are in parts per million. It has been used for provenancing stones (Aston et al 2000) and characterizing glass (Sayre and Smith 1961).

NAA; analyse par activation neutronique (Fr.); Neutronenactivierungsanalyse (Deut.); análise por activação neutrónica (Port.)

Neutron radiography

== Description ==
Neutron radiography is a radiographic technique based on the use of neutrons (instead of classical X-rays).It has a minor role in the cultural heritage area, but it could be a complementary technique if one wants for instance, to look for organic materials inside a closed metal object. The difference between neutron and X-ray interaction mechanisms produce significantly different and sometimes complementary information. While X-ray attenuation is directly dependent on atomic number, neutrons are efficiently attenuated by only a few specific elements like hydrogen, boron, rare earths, cobalt, lithium, indium, mercury, gold, silver…. For example, organic materials or water are clearly visible in neutron radiographs because of their high hydrogen content, while many structural materials such as aluminium, steel or lead are nearly transparent. The examination must be done in a thermal neutron beam extracted from a research nuclear reactor, like the one dedicated to this technique at the Orphée reactor at CEA – Saclay.

Newsprint

== Description ==
An inexpensive paper used for printing newspapers and student sketch pads. Newsprint is primarily made from mechanical pulp (>85%) with some chemical pulp and very little mineral content. It is produced by high speed machines which result in unidirectional fiber orientation. Newsprint is strong, has good opacity, a smooth, lint-free surface and high oil absorption. Intended only for short term use, newsprint has a high lignin content and degrades quickly by discoloring and becoming brittle.

Nickel

== Description ==
A silvery-white, magnetic metallic element. Nickel occurs naturally in many ores such as nicolite, pyrrhotite, pentlandite, and garnierite as well as in metallic meteorites. Its abundance in the earth's crust is 99 ppm and large reserves are located in Ontario, Norway, Finland, Cuba, China, and Australia. Nickel was first isolated by Axel F. Cronstedt in 1751. Metallic nickel is a hard, malleable metal that can take a high polish and remain untarnished. It is most often used as a protective and ornamental electroplated coatings on other metals, such as iron and steel. Nickel is also used to produce Monel®, a highly corrosion resistant nickel-copper alloy, as well as many other alloys. In Europe, nickel is prohibited in jewelry, watches, and zippers because of its carcinogenic potential via skin absorption.
