Dutch researcher Bart de Graaf has developed a solid oxygen carrier, a sort of oxygen sponge. The oxygen from the sponge reacts with hydrogen to produce water. With De Graafs discovery a lot of energy can be saved during the production of raw materials for plastics.
Hydrogen is released during the conversion of ethane and propane to ethylene and propylene, raw materials for the production of plastics. Using oxygen from a so-called oxygen sponge to convert hydrogen into water saves a lot of energy during the production process.
The oxygen sponge only reacts with the hydrogen released and not with other compounds in the chemical reaction, such as ethane and propane. This allows more starting materials to be converted in one cycle and makes the separation of the starting material and product both easier and cheaper. This new process therefore saves a lot of energy.

Innsbruck quantum physicists have constructed a diode for magnetic fields and then tested it in the laboratory. The device, developed by the research groups led by the theorist Oriol Romero-Isart and the experimental physicist Gerhard Kirchmair, could open up a number of new applications.
Electric diodes are essential electronic components that conduct electricity in one direction but prevent conduction in the opposite one. They are found at the...
Max Planck researchers revel the nano-structure of molecular trains and the reason for smooth transport in cellular antennas.
Moving around, sensing the extracellular environment, and signaling to other cells are important for a cell to function properly. Responsible for those tasks...
Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
