Terraria ( / təˈrɛəriə / ⓘ [ 1]) is a 2011 action-adventure sandbox game developed by Re-Logic. The game was first released for Windows and has since been ported to other PC and console platforms. The game features exploration, crafting, building, painting, and combat with a variety of creatures in a procedurally generated 2D world ...
Terraria: A bright-green metal found deep beneath the jungle, implied to be the toughest ore that can be mined from the ground (topped only by Luminite, a material dropped by the final boss). True to its name, Chlorophyte has plant-themed properties, and can be used to craft armor and weapons that harness the powers of plants.
The 4n chain of thorium-232 is commonly called the "thorium series" or "thorium cascade". Beginning with naturally occurring thorium-232, this series includes the following elements: actinium, bismuth, lead, polonium, radium, radon and thallium. All are present, at least transiently, in any natural thorium-containing sample, whether metal ...
Terrarium. A terrarium ( pl.: terraria or terrariums) is usually a sealable glass container containing soil and plants that can be opened for maintenance to access the plants inside; however, terraria can also be open to the atmosphere. Terraria are often kept as ornamental items. A closed terrarium's transparent walls allow heat and light to ...
A molten-salt reactor ( MSR) is a class of nuclear fission reactor in which the primary nuclear reactor coolant and/or the fuel is a mixture of molten salt with a fissile material. Two research MSRs operated in the United States in the mid-20th century. The 1950s Aircraft Reactor Experiment (ARE) was primarily motivated by the technology's ...
Thorium ( 90 Th) has seven naturally occurring isotopes but none are stable. One isotope, 232 Th, is relatively stable, with a half-life of 1.405×10 10 years, considerably longer than the age of the Earth, and even slightly longer than the generally accepted age of the universe. This isotope makes up nearly all natural thorium, so thorium was ...
Thorium reacts with hydrogen to form the thorium hydrides ThH 2 and Th 4 H 15, the latter of which is superconducting below the transition temperature of 7.5–8 K; at standard temperature and pressure, it conducts electricity like a metal. [12] Thorium is the only metallic element that readily forms a hydride higher than MH 3. [31]
Thorium is a future potential source of low-carbon energy. [1] Thorium has been demonstrated to perform as a nuclear fuel in several reactor designs. [2] [3] It is present with a higher abundance than uranium in the crust of the earth. Thorium resources have not been estimated and assessed with a higher level of confidence, as in the case of ...
