what is atenolol It’s not just about showing off. For the woman, Judith Saunders, who fought for her wedding ring back, she’s not fighting for a √ā¬£550 ring but for an object with real personal meaning. Even for those who are bitterly divorced, a wedding ring is a sign of the hope before the reality; a time when couples are willing to pour their money into an item of jewellery for the sake of announcing their love to the world.

Michael Grštzel wins the Millennium Technology Prize

09 June 2010

A sum of 800,000 Euros, the Millennium Technology Prize was give today, the 9th of June, to EPFL professor Michael Grätzel. The jury in Helsinki has awarded the prize for the extraordinary career of the man whose dye-sensitized solar cells that bear his name.


One honor after another for Michael Grätzel—after consecrating thirty years to the development of dye-sensitized solar cells, the chemist and professor at Ecole Polytechnique Fédérale de Lausanne (EPFL) is among the ten most-cited scientists in the world. And now he has just been awarded the Millennium Technology Prize in Helsinki, one of the most prestigious awards for scientific excellence at a sum of 800,000 Euros.  

Inspired by photosynthesis, this unique form of solar cell has only recently been commercialized. These dyed-sensitized solar cells cost less to produce than conventional silica based cells and are also more versatile, making them one of the most promising technologies in the field of renewable energy. Michaël Grätzel has also worked on improving next-generation li-on batteries by making them safer and more efficient and solar energy storage using hydrogen extraction—unlocking a potent carbon-free energy source that could one day replace petrol.
Instituted in 2004, the Millennium Technology Prize is one of the most widely-followed award in the field. Given by the Technology Academy Finland, a composition of Finnish government and industry, the award is for innovative applied science that contributes directly to the well-being of all. By awarding its highest honor to Michael Grätzel, the jury shows its firm confidence in the future of the dye-sensitized cells also known as Grätzel cells.
