The separation of gas molecules and isotopes is of great interest for analytical purposes. Furthermore, pure radio isotopes are required in nuclear medicine for diagnostic procedures and radiotherapy.<br><br> <strong>Technology</strong><br> This method and device enables the separation of gas molecules having different excitation spectra. Therefore it is possible to separate molecules with different chemical and/ or physical properties as well as to separate isotopes. The molecules are excited by laser pulses. Due to multi-photon absorption the molecules to be separated are transferred into a multi-excited or ionized state in which they can be separated from other gas components. Multi-excited molecules can be extracted chemically or by electromagnetic field and ionized molecules can be separated by electrostatic field (e.g. quadrupole mass spectrometry). The extracted molecules are analyzed and the laser pulses are shaped (amplitude, phase, duration) by an iterative process depending on feedback analysis of the extracted molecules. This procedure is repeated until the composition of the extracted molecules is optimized according to a predefined composition.<br><br> <b>Benefits:</b><br>

The IPH presents a solution at HANNOVER MESSE 2015 to make ship traffic more reliable while decreasing the maintenance costs at the same time. In cooperation with project partners, the research institute from Hannover, Germany, has developed a sensor system which continuously monitors the condition of the marine gearbox, thus preventing breakdowns. Special feature: the monitoring system works wirelessly and energy-autonomously. The required electrical power is generated where it is needed – directly at the sensor.
As well as cars need to be certified regularly (in Germany by the TÜV – Technical Inspection Association), ships need to be inspected – if the powertrain stops...
When an earthquake hits, the faster first responders can get to an impacted area, the more likely infrastructure--and lives--can be saved.
The Atlantic overturning is one of Earth’s most important heat transport systems, pumping warm water northwards and cold water southwards. Also known as the Gulf Stream system, it is responsible for the mild climate in northwestern Europe.
Scientists now found evidence for a slowdown of the overturning – multiple lines of observation suggest that in recent decades, the current system has been...
Because they are regularly subjected to heavy vehicle traffic, emissions, moisture and salt, above- and underground parking garages, as well as bridges, frequently experience large areas of corrosion. Most inspection systems to date have only been capable of inspecting smaller surface areas.
From April 13 to April 17 at the Hannover Messe (hall 2, exhibit booth C16), engineers from the Fraunhofer Institute for Nondestructive Testing IZFP will be...
