Groundbreaking work by a team of chemists on a fringe element of the periodic table could change how the world stores radioactive waste and recycles fuel.
The element is called californium — Cf if you’re looking at the Periodic Table of Elements — and it’s what Florida State Professor Thomas Albrecht-Schmitt, the lead researcher on the project, calls “wicked stuff.”
In carefully choreographed experiments, Albrecht-Schmitt and his colleagues found that californium had amazing abilities to bond and separate other materials. They also found it was extremely resistant to radiation damage.
“It’s almost like snake oil,” he said. “It sounds almost too good to be true.”
Albrecht-Schmitt said that the discoveries could help scientists build new storage containers for radioactive waste, plus help separate radioactive fuel, which means the fuel could be recycled.
“This has real world application,” he said. “It’s not purely an academic practice.”
Albrecht-Schmitt’s work, “Unusual Structure, Bonding, and Properties in a Californium Borate,” appears published in the newest edition of Nature Chemistry.
But, running the experiments and collecting the data were not small tasks.
After years of working with the U.S. Department of Energy, Albrecht-Schmitt obtained 5 milligrams of californium costing $1.4 million, paid for through an endowment to the university in honor of retired professor Gregory Choppin.
But that tiny, expensive element has opened a whole new world of nuclear chemistry.
“We’re changing how people look at californium and how it can be used,” Albrecht-Schmitt said.
All of the experiments were conducted at Florida State, but Albrecht-Schmitt also worked with theorists and scientists from nine universities and institutes, including Oak Ridge National Laboratory, which supplied the californium.
David A. Dixon, professor of chemistry at the University of Alabama, and his graduate student, Ted Garner, provided the calculations and theory on why the californium could bond in such unique ways, while scientists at Argonne National Laboratory helped correlate the theory with the experiments. Evgeny Alekseev and Wulf Depmeier of Germany also provided an improved understanding on the atomic structure of californium.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
