Stardew Valley was originally titled Sprout Valley and was created by American indie game designer Eric Barone, known professionally as ConcernedApe. [ 6 ] [ 7 ] [ 8 ] Barone graduated from the University of Washington Tacoma in 2011 with a computer science degree but was unable to get a job in the industry, instead working as an usher at the ...
Osmiridium has been defined as containing a higher proportion of iridium, with iridosmine containing more osmium. However, as the content of the natural Os-Ir alloys varies considerably, the constituent percentages of specimens often reflects the reverse situation of osmiridium describing specimens containing a higher proportion of osmium and ...
The international prototype of the kilogram (IPK) is an artifact standard of platinum–iridium alloy that was defined as having a mass of exactly one kilogram. Platinum–iridium alloys are alloys of the platinum group precious metals platinum and iridium. Typical alloy proportions are 90:10 or 70:30 (Pt:Ir).
Within Earth's crust, osmium, like iridium, is found at highest concentrations in three types of geologic structure: igneous deposits (crustal intrusions from below), impact craters, and deposits reworked from one of the former structures.
Iridium(IV) oxide, IrO 2, is the only well-characterised oxide of iridium. It is a blue-black solid. It is a blue-black solid. The compound adopts the TiO 2 rutile structure , featuring six coordinate iridium and three coordinate oxygen.
Iridium(III) iodide is a dark brown solid that is insoluble in water. [1] It is monoclinic like chromium trichloride . [ 5 ] [ 6 ] Its trihydrate is yellow and can be dehydrated into the dihydrate or anhydrous form on heating.
Iridium-192 (symbol 192 Ir) is a radioactive isotope of iridium, with a half-life of 73.83 days. [11] It decays by emitting beta (β) particles and gamma (γ) radiation. About 96% of 192 Ir decays occur via emission of β and γ radiation, leading to 192 Pt. Some of the β particles are captured by other 192 Ir nuclei, which are then converted ...
Organoiridium compounds share many characteristics with those of rhodium, but less so with cobalt. Iridium can exist in oxidation states of -III to +V, but iridium(I) and iridium(III) are the more common. iridium(I) compounds (d 8 configuration) usually occur with square planar or trigonal bipyramidal geometries, whereas iridium(III) compounds (d 6 configuration) typically have an octahedral ...
