3 Φεβ 2021 · This time, a new theory to explain a sixty-year-old mystery surrounding the icy deaths of a group of Russian students, and the continued controversy about the chances of life on Venus.
4 Φεβ 2021 · EXPLOSIVE FINDINGS. Einsteinium (Es) is the 99th element in the periodic table. It was first discovered in 1952 when a thermonuclear device dubbed “Ivy Mike” was detonated on the island of Elugelab in the Pacific Ocean (now part of the Marshall Islands). Ivy Mike’s detonation was the first demonstration of a hydrogen bomb.
Einsteinium is a synthetic chemical element; it has symbol Es and atomic number 99. It is named after Albert Einstein and is a member of the actinide series and is the seventh transuranium element. Einsteinium was discovered as a component of the debris of the first hydrogen bomb explosion in 1952.
Despite working with less than 200ng of the element, the researchers managed to put einsteinium through x-ray absorption measurements, revealing its coordination chemistry and spectroscopic ...
