The percentage of an element produced in the top producing country. The higher the value, the larger risk there is to supply. Argon Eon is a really interesting case. It offers a perfectly reasonable home NAS while not limiting itself to network storage use cases only. Tinkering with a device that keeps your data safe, isn’t the best approach, but the GPIO header offers physical interactions (on already tested projects) and Raspberry Pi 4 inside provides enough headroom to handle storage and additional services you may need in your home. Unlike other NAS enclosures, it’s not an eye sore and doesn’t have to be hidden away. If you have any questions, use this Reddit thread. The overall performance will depend on what are your typical use cases like. Can a family of 5 stream videos from Argon Eon at the same time? Unlikely, but if that’s your goal, you will need a bigger budget and a more complex solution. Argon is extracted industrially by the fractional distillation of liquid air. Argon is mostly used as an inert shielding gas in welding and other high-temperature industrial processes where ordinarily unreactive substances become reactive; for example, an argon atmosphere is used in graphite electric furnaces to prevent the graphite from burning. Argon is also used in incandescent, fluorescent lighting, and other gas-discharge tubes. Argon makes a distinctive blue-green gas laser. Argon is also used in fluorescent glow starters.

Regarding the Hard Disk Temperature, we did some tests and with the Raspberry Pi 4 in IDLE the CPU temp remains at 50C or below (even at our 30C ambient temp) and the mechanical drives were running between 40C-45C. At these temp ranges most manufacturers would rate their HDDs to work safely. Alaska FACE Investigation 94AK012 (23 June 1994).

Argon produced directly by stellar nucleosynthesis is dominated by the alpha-process nuclide 36Argon has been used by athletes as a doping agent to simulate hypoxic conditions. In 2014, the World Anti-Doping Agency (WADA) added argon and xenon to the list of prohibited substances and methods, although at this time there is no reliable test for abuse. [52] Safety Other noble gases would be equally suitable for most of these applications, but argon is by far the cheapest. Argon is inexpensive, since it occurs naturally in air and is readily obtained as a byproduct of cryogenic air separation in the production of liquid oxygen and liquid nitrogen: the primary constituents of air are used on a large industrial scale. The other noble gases (except helium) are produced this way as well, but argon is the most plentiful by far. The bulk of argon applications arise simply because it is inert and relatively cheap.

After intall you may want to modify the fan configuration to match your environment You can change the default temperature setting by editing the file /etc/argoneon.conf. The fan will be triggered by one of two separate settings, the CPU temperature, or the HDD temperature. Which ever component passes the set threashold first will cause the fan to turn on. For instance, if your HDD temp hits 35C, the fan will turn on at 30%, even if the CPU temp is running below 55C. Uninstall Gastler, Dan; Kearns, Ed; Hime, Andrew; Stonehill, Laura C.; etal. (2012).

S2CID 6876533. In a theory of chemical bonding advanced by American chemist Gilbert N. Lewis and German chemist Walther Kossel in 1916, this octet of electrons was taken to be the most stable arrangement for the outermost shell of any atom. Although only the noble-gas atoms possessed this arrangement, it was the condition toward which the atoms of all other elements tended in their chemical bonding. Certain elements satisfied this tendency by either gaining or losing electrons outright, thereby becoming ions; other elements shared electrons, forming stable combinations linked together by covalent bonds. The proportions in which atoms of elements combined to form ionic or covalent compounds (their “ valences”) were thus controlled by the behaviour of their outermost electrons, which—for this reason—were called valence electrons. This theory explained the chemical bonding of the reactive elements, as well as the noble gases’ relative inactivity, which came to be regarded as their chief chemical characteristic. ( See also chemical bonding: Bonds between atoms.) To give you a reference a naked Raspberry Pi 4 board runs at about 52℃ idle and goes all the way to 82℃ where it throttles the speed of the CPU. NAS performance Argon's complete octet of electrons indicates full s and p subshells. This full valence shell makes argon very stable and extremely resistant to bonding with other elements. Before 1962, argon and the other noble gases were considered to be chemically inert and unable to form compounds; however, compounds of the heavier noble gases have since been synthesized. The first argon compound with tungsten pentacarbonyl, W(CO) 5Ar, was isolated in 1975. However, it was not widely recognised at that time. [29] In August 2000, another argon compound, argon fluorohydride (HArF), was formed by researchers at the University of Helsinki, by shining ultraviolet light onto frozen argon containing a small amount of hydrogen fluoride with caesium iodide. This discovery caused the recognition that argon could form weakly bound compounds, even though it was not the first. [10] [30] [31] It is stable up to 17kelvins (−256°C). The metastable ArCF 2+Solid argon hydride (Ar(H 2) 2) has the same crystal structure as the MgZn 2 Laves phase. It forms at pressures between 4.3 and 220 GPa, though Raman measurements suggest that the H 2 molecules in Ar(H 2) 2 dissociate above 175 GPa.

Where more than one isotope exists, the value given is the abundance weighted average.
