ORNL meets key FDA milestone for cancer-fighting Ac-225 isotope

A rare isotope in high demand for treating cancer is now more available to pharmaceutical companies developing and testing new drugs. The U.S. Food and Drug Administration recently received Oak Ridge National Laboratory’s drug master file for actinium-225 nitrate, which lets pharmaceutical companies reference the document to support applications for their own Ac-225-based drugs without disclosing proprietary information.

Do You Know the Way to Berkelium, Californium?

Scientists at Berkeley Lab have demonstrated how to image samples of heavy elements as small as a single nanogram. The new approach will help scientists advance new technologies for medical imaging and cancer therapies.

Isotope Discovery Continues: Mass Identification Confirms Production of a New Isotope of Mendelevium

Neighboring isotopes of the heaviest elements often have very similar properties. To differentiate these isotopes by their differing masses, scientists use a device called FIONA (For the Identification of Nuclide A) to measure the masses of heavy-element isotopes. For the first time, scientists have used FIONA to discover a new heavy-element isotope, mendelevium-244.

Blocking vibrations that remove heat could boost efficiency of next-gen solar cells

Led by the Department of Energy’s Oak Ridge National Laboratory and the University of Tennessee, Knoxville, a study of a solar-energy material with a bright future revealed a way to slow phonons, the waves that transport heat.

Atomic fingerprint identifies emission sources of uranium

Uranium is not always the same: depending on whether this chemical element is released by the civil nuclear industry or as fallout from nuclear weapon tests, the ratio of the two anthropogenic, i.e. man-made, uranium isotopes 233U and 236U varies. These results were lately found by an international team grouped around physicists from the University of Vienna and provides a promising new “fingerprint” for the identification of radioactive emission sources.
