Nautica is a designer outerwear company founded by David Chu in 1983.
Since its global inception almost two decades ago, Nautica has evolved into a complete lifestyle brand. The line of products includes Nautica Sportswear, Jeans, Tailored, Swimwear, Sleepwear, Boys, a full line of accessories including Eyewear, Watches and Fragrances, and a Nautica Home Collection. It is often worn by men and women of a higher income bracket who also indulge in the wearing of brand names such as Polo Ralph Lauren and Gant USA.
The brand is now owned by the VF Corporation.

The brand is now owned by the VF Corporation. Elevated 20Ne abundances are also found in diamonds, further suggesting a solar neon reservoir in the Earth. It is often worn by men and women of a higher income bracket who also indulge in the wearing of brand names such as Polo Ralph Lauren and Gant USA. The 20Ne-enriched components are attributed to exotic primordial rare gas components in the Earth, possibly representing solar neon. The line of products includes Nautica Sportswear, Jeans, Tailored, Swimwear, Sleepwear, Boys, a full line of accessories including Eyewear, Watches and Fragrances, and a Nautica Home Collection. The neon isotopic content of these mantle-derived samples represent a non-atmospheric source of neon. Since its global inception almost two decades ago, Nautica has evolved into a complete lifestyle brand. Similar to xenon, neon content observed in samples of volcanic gases are enriched in 20Ne, as well as nucleogenic 21Ne, relative to 22Ne content.
Nautica is a designer outerwear company founded by David Chu in 1983. This suggests that neon will be a useful tool in determining cosmic exposure ages of surficial rocks and meteorites. See Nautica Thorn for the Hawaiian pornstar. By analyzing all three isotopes, the cosmogenic component can be resolved from magmatic neon and nucleogenic neon. This isotope is generated by spallation reactions on magnesium, sodium, silicon, and aluminium. Isotopic analysis of exposed terrestrial rocks has demonstrated the cosmogenic production of 21Ne.
The net result yields a trend towards lower 20Ne/22Ne and higher 21Ne/22Ne ratios observed in uranium-rich rocks such as granites. The alpha particles are derived from uranium-series decay chains, while the neutrons are mostly produced by secondary reactions from alpha particles. The principal nuclear reactions which generate neon isotopes are neutron emission, alpha decay reactions on 24Mg and 25Mg, which produce 21Ne and 22Ne, respectively. In contrast, 20Ne is not known to be nucleogenic and the causes of its variation in the Earth have been hotly debated.
21Ne and 22Ne are nucleogenic and their variations are well understood. Neon has three stable isotopes: 20Ne (90.48%), 21Ne (0.27%) and 22Ne (9.25%). In addition, neon forms an unstable hydrate. The ions, Ne+, (NeAr)+, (NeH)+, and (HeNe+), have been observed from optical and mass spectrometric research.
Argon, in contrast, is heavier than air and so remains within Earth's atmosphere. Neon, like water vapor, is lighter than air; unlike water vapor, which condenses into a liquid below the stratosphere and is thus trapped in Earth's atmosphere, neon may slowly leak out into space, which explains its scarcity on Earth. Neon is a rare gas that is found in the Earth's atmosphere at 1 part in 65,000 and is produced by supercooling air and fractionally distilling it from the resulting cryogenic liquid. Neon is usually found in the form of a gas with molecules consisting of a single neon atom.
Neon (Greek neos meaning "new") was discovered by Scottish chemist William Ramsay and English chemist Morris Travers in 1898. Other uses:. The word "neon" is also used generically for these types of lights when in reality many other gases are used to produce different colors of light. The reddish-orange color that neon emits in neon lights is widely used to make advertising signs.
Neon has the most intense discharge at normal voltages and currents of all the rare gases. In most applications it is a less expensive refrigerant than helium. Neon is the second-lightest noble gas, glows reddish-orange in a vacuum discharge tube and has over 40 times the refrigerating capacity of liquid helium and three times that of liquid hydrogen (on a per unit volume basis). .
A colorless nearly inert noble gas, neon gives a distinct reddish glow when used in vacuum discharge tubes and neon lamps and is found in air in trace amounts. Neon is the chemical element in the periodic table that has the symbol Ne and atomic number 10. Los Alamos National Laboratory – Neon. Liquefied neon is commercially used as an economical cryogenic refrigerant.
Neon and helium are used to make a type of gas laser. television tubes. wave meter tubes. lightning arrestors.
