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: Self-assembling nano inks form conductive and transparent grids during imprint

Transparent electronics devices are present in today’s thin film displays, solar cells, and touchscreens. The future will bring flexible versions of such devices. Their production requires printable materials that are transparent and remain highly conductive even when deformed. Researchers at INM – Leibniz Institute for New Materials have combined a new self-assembling nano ink with an imprint process to create flexible conductive grids with a resolution below one micrometer.

To print the grids, an ink of gold nanowires is applied to a substrate. A structured stamp is pressed on the substrate and forces the ink into a pattern. “The...

Im Focus: The Glowing Brain

A new Fraunhofer MEVIS method conveys medical interrelationships quickly and intuitively with innovative visualization technology

On the monitor, a brain spins slowly and can be examined from every angle. Suddenly, some sections start glowing, first on the side and then the entire back of...

Im Focus: Newly discovered material property may lead to high temp superconductivity

Researchers at the U.S. Department of Energy's (DOE) Ames Laboratory have discovered an unusual property of purple bronze that may point to new ways to achieve high temperature superconductivity.

While studying purple bronze, a molybdenum oxide, researchers discovered an unconventional charge density wave on its surface.

Im Focus: Mapping electromagnetic waveforms

Munich Physicists have developed a novel electron microscope that can visualize electromagnetic fields oscillating at frequencies of billions of cycles per second.

Temporally varying electromagnetic fields are the driving force behind the whole of electronics. Their polarities can change at mind-bogglingly fast rates, and...

Im Focus: Continental tug-of-war - until the rope snaps

Breakup of continents with two speed: Continents initially stretch very slowly along the future splitting zone, but then move apart very quickly before the onset of rupture. The final speed can be up to 20 times faster than in the first, slow extension phase.phases

Present-day continents were shaped hundreds of millions of years ago as the supercontinent Pangaea broke apart. Derived from Pangaea’s main fragments Gondwana...
