Lactaldehyde is a three-carbon atom species with a carbonyl group on the first carbon atom (making it an aldehyde), and a hydroxy group on the second carbon atom, making it a secondary alcohol.
Its major isotope 231 Pa has a specific activity of 0.048 curies (1.8 GBq) per gram and primarily emits alpha-particles with an energy of 5 MeV, which can be stopped by a thin layer of any material. However, it slowly decays, with a half-life of 32,760 years, into 227 Ac, which has a specific activity of 74 curies (2,700 GBq) per gram, emits ...
Uranium-232 (232 U) is an isotope of uranium.It has a half-life of around 69 years and is a side product in the thorium cycle.It has been cited as an obstacle to nuclear proliferation using 233 U as the fissile material, because the intense gamma radiation emitted by 208 Tl (a daughter of 232 U, produced relatively quickly) makes the 233 U contaminated with it more difficult to handle.
A chemical formula is a way of expressing information about the proportions of atoms that constitute a particular chemical compound, using chemical symbols for the chemical elements, and subscripts to indicate the number of atoms involved. For example, water is composed of two hydrogen atoms bonded to one oxygen atom: the chemical formula is H 2 O.
However, there is no real demand in chemistry, physics, or engineering for isolating 234 U. Very small pure samples of 234 U can be extracted via the chemical ion-exchange process, from samples of plutonium-238 that have aged somewhat to allow some alpha decay to 234 U.
Brad Pitt and Angelina Jolie have reached a settlement in their divorce eight years after the Maria star filed to end their two-year marriage, citing irreconcilable differences.. Jolie, 49, and ...
Depending on the brand of windshield wiper fluid used, Burgett says the methanol, ethanol, isopropyl alcohol and glycols, or a combination of these ingredients in the formula, can help lower the ...
Molten-Salt Reactor Experiment Shippingport Atomic Power Station German THTR-300. In 1946, the public first became informed of uranium-233 bred from thorium as "a third available source of nuclear energy and atom bombs" (in addition to uranium-235 and plutonium-239), following a United Nations report and a speech by Glenn T. Seaborg.
