Optical Pulse Shaping for Enhanced Separation of molecules and isotopes

12.12.2012
<strong>Background</strong><br>

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>

<ul> <li>Enables separation of molecules without prior analysis</li> <li>Evolutionary Algorithm → no prior calculations are required</li> <li>Exact calculations are not necessary due to the iterative process </li> </ul><br> <strong>IP Rights</strong><br> German patent DE 103 36 057 B4 <br> US Patent US 7,276,103 B2 <br> <br> <strong>Origin</strong><br> Freie Universität Berlin, Germany

Im Focus: Erosion, landslides and monsoon across the Himalaya

Scientists from Nepal, Switzerland and Germany was now able to show how erosion processes caused by the monsoon are mirrored in the sediment load of a river crossing the Himalaya.

In these days, it was again tragically demonstrated that the Himalayas are one of the most active geodynamic regions of the world. Landslides belong to the...

Im Focus: Through the galaxy by taxi - The Dream Chaser Space Utility Vehicle

A world-class prime systems integrator and electronic systems provider known for its rapid, innovative, and agile technology solutions, Sierra Nevada Corporation (SNC) is currently developing a new space transportation system called the Dream Chaser.

The ultimate aim is to construct a multi-mission-capable space utility vehicle, while accelerating the overall development process for this critical capability...

Im Focus: High-tech textiles – more than just clothes

Today, textiles are used for more than just clothes or bags – they are high tech materials for high-tech applications. High-tech textiles must fulfill a number of functions and meet many requirements. That is why the Fraunhofer Institute for Silicate Research ISC dedicated some major developing work to this most intriguing research area. The result can now be seen at Techtextil trade show in Frankfurt from 4 to 7 May. On display will be novel textile-integrated sensors, a unique multifunctional coating system for textiles and fibers, and textile processing of glass, carbon, and ceramics fibers to fiber preforms.

Thin materials and new kinds of sensors now make it possible to integrate silicone elastomer sensors in textiles. They are suitable for applications in medical...
