In the webcomic The Order of the Stick, the main villain Xykon is a lich. [13] In the Harry Potter series, the main antagonist Voldemort commands armies of undead inferi and uses magical devices called horcruxes to store fragments of his soul in order to allow him to resurrect himself in the event that his body dies.

A sample of thorium. Thorium-based nuclear power generation is fueled primarily by the nuclear fission of the isotope uranium-233 produced from the fertile element thorium.A thorium fuel cycle can offer several potential advantages over a uranium fuel cycle [Note 1] —including the much greater abundance of thorium found on Earth, superior physical and nuclear fuel properties, and reduced ...
The thorium fuel cycle is a nuclear fuel cycle that uses an isotope of thorium, 232 Th, as the fertile material. In the reactor, 232 Th is transmuted into the fissile artificial uranium isotope 233 U which is the nuclear fuel. Unlike natural uranium, natural thorium contains only trace amounts of fissile material (such as 231 Th
World of Warcraft: Wrath of the Lich King is the second expansion set for the massively multiplayer online role-playing game (MMORPG) World of Warcraft, following The Burning Crusade. It launched on November 13, 2008 and sold 2.8 million copies within the first day, making it the fastest selling computer game of all time released at that point.
Two radiometric dating methods involve thorium isotopes: uranium–thorium dating, based on the decay of 234 U to 230 Th, and ionium–thorium dating, which measures the ratio of 232 Th to 230 Th. [e] These rely on the fact that 232 Th is a primordial radioisotope, but 230 Th only occurs as an intermediate decay product in the decay chain of ...
Thorium-232 is a fertile material; it can capture a neutron to form thorium-233, which subsequently undergoes two successive beta decays to uranium-233, which is fissile. As such, it has been used in the thorium fuel cycle in nuclear reactors; various prototype thorium-fueled reactors have been designed. However, as of 2024, thorium fuel has ...
Monazite contains 2.5% thorium, allanite has 0.1 to 2% thorium and zircon can have up to 0.4% thorium. [2] Thorium-containing minerals occur on all continents. [ 3 ] [ 4 ] [ 5 ] Thorium is several times more abundant in Earth's crust than all isotopes of uranium combined and thorium-232 is several hundred times more abundant than uranium-235.
ThCl 4 was an intermediate in the original isolation of thorium metal by Jons Jacob Berzelius. [2] Thorium(IV) chloride can be produced in a variety of ways. One method is a carbothermic reaction, 700 °C to 2600 °C, involving thorium oxides and carbon in a stream of chlorine gas: ThO 2 + 2 C + 4 Cl 2 → ThCl 4 + 2 CO
