Young stars ejecting plasma could give us clues into the Sun’s past Kyoto, Japan — Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs). They often occur together with sudden brightenings called flares, and sometimes extend far enough to disturb Earth’s magnetosphere, generating space weather phenomena including auroras or geomagnetic storms, and even damaging power grids on occasion. Scientists believe that when…

Future electro-mobility concepts require advanced battery technologies. Main drawbacks today are restrictions in energy density, cycling stability, and cost. The presented invention provides a solution that helps to overcome these problems. Extensive laboratory tests have already demonstrated the advantages of the invented process for preparing lithium-ion battery electrodes. Further improvement is currently under development. PROvendis offers licenses for this invention to interested companies on behalf of the University of Muenster, Germany.
Perfusion analysis in animal models (e.g. myocardial infarction) is currently determined by using fluorescent particles or dyes that are injected into circulation. They distribute throughout all blood vessels and stain them permanently. Thus it is possible to distinguish areas that are supplied with blood and those that are not. Since the dyes are long-lasting in the tissues they interfere with subsequent methods of analysis. A model animal that is used for perfusion analytics can therefore only be used for this specific analytical method.
The present invention overcomes these drawbacks by injecting non fluorescent inert particles that are the first component of an orthogonal system. After perfusion with these particles, the second component is added to frozen tissue sections of interest. Thus, perfusion analysis is solely performed on a selected tissue section, without any limitations for the remaining tissue.
This approach allows a background-free subsequent tissue analysis, optimizes data harvest, is economic and reduces animal consumption.

The invention relates to the usage of a tunable, resonant electromagnetic field for both, the targeted fabrication of structures with dimensions smaller than the used beam diameter and the targeted fabrication of ultra small particles. Therefor the electromagnetic field that is created by an ultra short laser pulse on the surface of an object is superposed with an external field to achieve a resonance rise specific to the processed material.
