At its inception, the periodic table sorted elements by weight, so it may be surprising that the heaviest natural element on Earth remains controversial, or at best, nebulous. In the strange, perhaps-unfinished search for this weightiest nucleus, the only definitive conclusion is that it lies somewhere beyond uranium.

TLDR
This review shall look at the historical developments that led to the field of element discovery, the attempts to discover superheavy elements in nature based on the island of stability, and the subsequent successful synthesis of elements and the implications of their half-lives and properties.

Synthesis of Uranium Single Atom from Radioactive Wastewater for Enhanced Water Dissociation and Hydrogen Evolution.
As a common nuclide in radioactive wastewater, uranium (U) is generally treated by landfill, which induces the massive abandonment of uranium resources. In this work, a pulse voltammetry method for
Circular chemistry to enable a circular economy
TLDR
By expanding the scope of sustainability to the entire lifecycle of chemical products, the concept of circular chemistry aims to replace today’s linear ‘take–make–dispose’ approach with circular processes and enable a closed-loop, waste-free chemical industry.

Beyond Uranium, Ca. 1890–1950
The transuranic elements at the end of the periodic table have since the 1960s been known as superheavy elements. Until 1939 no element heavier than uranium was known and yet there was in the earlier

Neutrons from spontaneous fission of long‐lived super‐ heavy nuclei
The investigations of spontaneous fission of 268Db (Z = 105) have been performed. 268Db is the heaviest nuclide for which the average number of neutrons per spontaneous fission ν = 4.2±1.0 was

Stars could produce our heavy elements through a rapid neutron-capture process during a supernova or merger of binary stars, but which is it? A study of 244Pu reveals that a rare event with a high
Attempt to detect primordial 244 Pu on Earth
