The anniversary thus marks an obvious time to reflect on nuclear. The nuclear choice is not black and white. It's not a simple "yes" or "no" decision. Rather, it's a matter of "yes but." What the world should do is stick with nuclear as part of its CO2-light mix of energy gen...

Tritium ā N'), English Name: tritium, also known as ultraheavy hydrogen, is one of the isotopes of hydrogen, the element symbol is t or 3h. its atomic nucleus is composed of one proton and two neutrons, and has radioactivity, which will occur β Decay, with a half-life of 12.43 yea...
The hydrogen and oxygen isotope composition of waters at Libiola and Vigonzano agrees with their meteoric origin. Acid to neutral mine waters do not show any significant isotope shift with respect to the initial water, in spite of the oxidation of even large amounts of pyrite/chalcopyrite ore....
Instead, the Moon appears to contain multiple hydrogen reservoirs with diverse deuterium-to-hydrogen (D/H) ratios. For the first time, we incorporate hydrogen isotopic measurements of lunar samples to help constrain the composition of Theia. We show that the Moon incorporated very low-D/H (δD...
