Chemists have recently explored protactinium's multiple resemblances to more completely understand the relationship between the transition metals and the complex chemistry of the early actinide ...

Kasimir Fajans and O.H. Göhring first produced protactinium-234 in 1913 while examining the radioactive decay of uranium. They named the element brevium, which means brief. Following this, two groups ...

Many of us are often told we bear a resemblance to another member of our family — for instance, that we have our mother’s nose or our father’s eyes. Chemical elements on the periodic table also have ...

In 1980, the International Atomic Energy Agency (IAEA) observed that protactinium, a chemical element generated in thorium reactors, could be separated and allowed to decay to isotopically pure ...

A research team led by Chinese scientists has synthesized a novel, extremely neutron-deficient isotope, protactinium-210, for the first time, laying the foundation for new element synthesis ...

We have recently pointed out 1 that element 93 should have, according to the Periodic Law, other properties than those displayed by Fermi's element 93 2, and we found, on repeating his experiments ...

Scientists demonstrated that a positively charged protactinium dioxide ion may not exist in aqueous solution like other highly charged actinides, such as uranium and plutonium. Found naturally only in ...

During the last ice age, when thick ice covered the Arctic, many scientists assumed that the deep currents below that feed the North Atlantic Ocean and help drive global ocean currents slowed or even ...

SAMPLES of silt and sand are collected regularly from the estuary of the River Ribble as part of the programme of environmental monitoring conducted by the Ministry of Agriculture, Fisheries and Food ...
