Kandor (commonly known as the Bottle City of Kandor) [1] is a fictional city spared from the doomed world of Krypton in DC Comics' Superman titles. Before Krypton exploded, the futuristic city was captured by the supervillain Brainiac , miniaturized by his shrinking ray and placed inside a glass bell jar.
Krypton is usually portrayed in comics as the home of a fantastically advanced civilization, which is destroyed when the planet explodes. As originally depicted, all the civilizations and races of Krypton perished in the explosion, with one exception: the baby Kal-El who was placed in an escape rocket by his father, Jor-El, and sent to the planet Earth, where he grew up to become Superman.
Krypton is used in some photographic flashes for high speed photography. Krypton gas is also combined with mercury to make luminous signs that glow with a bright greenish-blue light. [39] Krypton is mixed with argon in energy efficient fluorescent lamps, reducing the power consumption, but also reducing the light output and raising the cost. [40]
Star City is the home of the Green Arrow. Its location has varied over the years; however, the DC Rebirth Green Arrow series specifically states it was originally Seattle, only later being renamed Star City. Star City in other media. In the Arrowverse, it was originally named Starling City before it was rebranded as Star City by Ray Palmer / Atom.
Kal-El can lead an alter ego as Clark Kent because Kryptonians appear identical to humans. Also, in both Silver Age and Modern Age continuity, Kryptonians have more than one ethnic group, such as dark-skinned Kryptonians from Krypton's Vathlo Island that resemble Earth humans of Sub-Saharan African, Negrito, Melanesian, and Indigenous Australian descent and a group from the continent of Twenx ...
Krypton-81 is useful in determining how old the water beneath the ground is. [10] Radioactive krypton-81 is the product of spallation reactions with cosmic rays striking gases present in the Earth atmosphere, along with the six stable or nearly stable krypton isotopes. [11] Krypton-81 has a half-life of about 229,000 years.
The xenon atom trapped in the fullerene can be observed by 129 Xe nuclear magnetic resonance (NMR) spectroscopy. Through the sensitive chemical shift of the xenon atom to its environment, chemical reactions on the fullerene molecule can be analyzed. These observations are not without caveat, however, because the xenon atom has an electronic ...
Krypton-85 (85 Kr) is a radioisotope of krypton.. Krypton-85 has a half-life of 10.756 years and a maximum decay energy of 687 keV. [1] It decays into stable rubidium-85.Its most common decay (99.57%) is by beta particle emission with a maximum energy of 687 keV and an average energy of 251 keV.
