A little-known element called californium is making big waves in how scientists look at the periodic table.
According to new research by a Florida State University professor, californium is what’s known to be a transitional element, meaning it links one part of the Periodic Table of Elements to the next.
Why’s that important?
Despite the fact that you may have memorized the periodic table in high school chemistry, there is actually very little known about the elements at the very end of the table. But, these elements are some of the heaviest and least understood chemical elements on the planet and information about them may prove crucial in the future as we look at how to store or recycle used nuclear fuel, among other things.
So learning what californium can or cannot do is a pretty big deal.
In a new Nature Communications paper, Professor Thomas Albrecht-Schmitt found that californium is an element that helps link one part of the periodic table to the next.
It has properties included in the three elements before it on the table — americium, curium and berkelium — and also the three elements after it — einsteinium, fermium and mendelevium. It gives the element unique capabilities that make it ripe for further research.
“This really changes how we think about the periodic table,” Albrecht-Schmitt said. “It’s important because we understand very little about these heavy elements. Governments and universities invest a lot of resources — financial, time and intellectual — into learning more about these elements.”
Getting a piece of californium is no easy task though.
After years of negotiating with the U.S. Department of Energy, Albrecht-Schmitt obtained 5 milligrams of californium through an endowment to the university in honor of retired Professor Gregory Choppin.
Those 5 milligrams have been the subject of multiple experiments, including several last year that led to Albrecht-Schmitt’s team discovering that californium had the ability to bond with and separate other materials.
This new round of experiments took almost two years to complete.
All the experiments were conducted at Florida State, but Albrecht-Schmitt worked with theorists and scientists from several other institutions including Oak Ridge National Laboratory, which supplied the californium, and the Florida State-based National High-Field Magnet Laboratory.
Other institutions contributing to the research are the University of Alabama and Argonne National Laboratory.

The Fraunhofer FEP has been involved in developing processes and equipment for cleaning, sterilization, and surface modification for decades. The CleanHand Network for development of systems and technologies to clean surfaces, materials, and objects was established in May 2018 to bundle the expertise of many partnering organizations. As a partner in the CleanHand Network, Fraunhofer FEP will present the Network and current research topics of the Institute in the field of hygiene and cleaning at the parts2clean trade fair, October 23-25, 2018 in Stuttgart, at the booth of the Fraunhofer Cleaning Technology Alliance (Hall 5, Booth C31).
Test reports and studies on the cleanliness of European motorway rest areas, hotel beds, and outdoor pools increasingly appear in the press, especially during...
The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved (nearly) freely in a quark-gluon plasma.
This is a joint press release of University Muenster and Heidelberg as well as the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt.
Then, in a phase transition, they combined and formed hadrons, among them the building blocks of atomic nuclei, protons and neutrons. In the current issue of...
Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.
"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...
A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.
Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...
