Building scaffolds using exotic elements: Research team succeeds in creating novel metal-organic frameworks
13-Sep-2022
Discovered 25 years ago, metal-organic frameworks (MOFs) quickly gained the aura of a “miracle material” due to their particular properties: their large inner surfaces and tuneable pore sizes facilitate improved applications, for example in materials separation and gas storage. While previous ...
Where does gold come from?
New insights into element synthesis in the universe
17-Nov-2021
How are chemical elements produced in our Universe? Where do heavy elements like gold and uranium come from? Using computer simulations, a research team from the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt, together with colleagues from Belgium and Japan, shows that the synthesis ...
Common table salt may have been crucial for the origins of life
30-Nov-2018
One of the most fundamental unexplained questions in modern science is how life began. Scientists generally believe that simple molecules present in early planetary environments were converted to more complex ones that could have helped jumpstart life by the input of energy from the environment. ...
Nitrogen fixation in ambient conditions
13-Nov-2018
Abundant in nature (78% of the air we breathe), nitrogen is rarely used in the industrial production of chemicals, with the most important process being the synthesis of ammonia, which is in turn used for the preparation of agricultural fertilizers. Using nitrogen as a raw material ("feedstock") ...
New properties of uranium compounds
17-Oct-2018
Scientists from Russia, China, and the United States predicted and experimentally identified new uranium hydrides, predicting superconductivity for some of them.Of particular interest to scientists are the so-called "high-temperature superconductors" that boast superconductivity at less extreme ...
Widespread uranium contamination found in India's groundwater
11-Jun-2018
A new Duke University-led study has found widespread uranium contamination in groundwater from aquifers in 16 Indian states. The main source of the uranium contamination is natural, but human factors such as groundwater-table decline and nitrate pollution may be exacerbating the problem. Several ...
Insight into a hidden order
23-Oct-2017
A specific uranium compound has puzzled researchers for thirty years. Although the crystal structure is simple, no one understands exactly what is happening once it is cooled below a certain temperature. Apparently, a “hidden order” emerges, whose nature is completely unknown.Now physicists have ...
Heavy elements in neutron star mergers detected
Predictions by GSI scientists confirmed
18-Oct-2017
Central predictions by GSI scientists on the formation of heavy elements such as gold and platinum in the universe have now been observed astrophysically. For the first time gravitational waves of merging neutron stars were detected. This also puts further focus on the future accelerator facility ...
Primordial black holes may have helped to forge heavy elements
08-Aug-2017
Astronomers like to say we are the byproducts of stars, stellar furnaces that long ago fused hydrogen and helium into the elements needed for life through the process of stellar nucleosynthesis. As the late Carl Sagan once put it: "The nitrogen in our DNA, the calcium in our teeth, the iron in ...
Bright thinking leads to breakthrough in nuclear threat detection science
03-Jul-2017
Taking inspiration from an unusual source, a Sandia National Laboratories team has dramatically improved the science of scintillators -- objects that detect nuclear threats. According to the team, using organic glass scintillators could soon make it even harder to smuggle nuclear materials ...
