Argon has approximately the same solubility in water as oxygen and is 2.5 times more soluble in water than nitrogen. Argon is colorless, odorless, nonflammable and nontoxic as a solid, liquid or gas. [11] Argon is chemically inert under most conditions and forms no confirmed stable compounds at room temperature.
Light emitted by ArO* has two main bands, one at 2.215 eV, and a weaker one at 2.195 eV. [51] Argon sulfide, ArS* luminesces in the near infrared at 1.62 eV. ArS is made from UV irradiated OCS in an argon matrix. The excited states lasts for 7.4 and 3.5 μs for spectrum peak and band respectively. [52]
The DUNE far detector design is based on state-of-the-art Liquid Argon Time Projection Chamber (LArTPC) technology. The far detector will consist of a total volume of 70-kilotons of liquid argon located deep underground, 1.5 kilometers (4,850 ft) under the surface. [19]
The thermal energy that is released from the bubble collapse is so great that it can cause weak light emission. [1] The mechanism of the light emission remains uncertain, but some of the current theories, which are categorized under either thermal or electrical processes, are Bremsstrahlung radiation, argon rectification hypothesis, [ 2 ] and ...
He first described dynamic soaring by seabirds in 1883, in the British journal Nature. [7] From 1887 to 1905 he was professor of Natural Philosophy at the Royal Institution. On this post he carefully and precisely measured atomic mass of oxygen and hydrogen, and by 1892 he moved on to nitrogen. By isolating nitrogen in different ways he ...
Additionally, krypton is a lighter ion, so the unit mass per ionization energy is further reduced compared to xenon. However, xenon can be more than ten times as expensive as krypton per kilogram , making krypton a more economical choice for building out satellite constellations like that of SpaceX 's Starlink V1, whose original Hall thrusters ...
The prices of the noble gases are influenced by their natural abundance, with argon being the cheapest and xenon the most expensive. As an example, the adjacent table lists the 2004 prices in the United States for laboratory quantities of each gas.
Argon flash, also known as argon bomb, argon flash bomb, argon candle, and argon light source, is a single-use source of very short and extremely bright flashes of light. The light is generated by a shock wave in argon or, less commonly, another noble gas. The shock wave is usually produced by an explosion. Argon flash devices are almost ...
