This is a Cm(III)-polyoxometalate complex isolated and characterized using the newly proposed technique that required only 1-10 micrograms of the precious radioisotope.

New Strategy Can Harvest Chemical Information on Rare Isotopes with a Fraction of the Material

A newly proposed approach aids chemical studies of rare, toxic, radioactive, and precious isotopes by requiring 1,000 times less material.

Fighting Cancer on Earth and in Space Using High-Energy Protons

Scientists on Earth use high-energy protons to create isotopes to detect and treat cancer. In space, however, these same high-energy protons can pose a risk to spacecraft and the health of the astronauts traveling in them.
