The Earth’s magnetic field is strong enough for some kinds of analyses – this opens up new opportunities for carrying out examinations under difficult conditions
Where x-rays no longer manage to see, magnets allow us to look inside. Patients know what that means: they lay down in the "tube" surrounded by an enormous electromagnet, the so-called MRI scanner. Such large pieces of equipment artificially create strong magnetic fields which enable doctors to take the pictures inside the patient’s body which they need for their diagnosis. Now scientists from the Research Centre Jülich, a Helmholtz Association institution, and the RWTH Aachen University of Technology have extended the spectrum of magnetic field scanning. Because they have discovered that the Earth’s natural magnetic field is strong enough for some examinations. And this closes a gap. Because it makes measurement with magnetic fields outdoors and under difficult conditions possible for the very first time. Although the applications will not initially be used in the field of medicine, they will make chemical analyses possible, such as when examining oil directly at source.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
