Degussa yesterday in Frankfurt signed a letter of intent with the Russian space-sector organizations TsSKB Progress (manufacturer of the Soyuz rocket) and TsENKI (responsible for launches and fuel supply to space vehicles), governing the supply of highly concentrated hydrogen peroxide (H2O2). “This agreement”, said Degussa executive Dr. Thomas Haeberle, Head of the Degussa Building Blocks division in charge of supplying the H2O2, “is the preliminary step to a future cooperation agreement between Degussa and these Russian companies.” The agreement initially covers five Soyuz rocket launches from the European space centre in Kourou, French Guiana, and encompasses delivery of a total of 50 tons through the end of 2009.
The European Space Agency (ESA) and the Russian Federation’s space agency (Roscosmos) had earlier signed an agreement on the launch of Soyuz rockets from Kourou. “We are currently building a new launch complex for Soyuz in French Guyana. The construction site was inaugurated in late February 2007,” said Dr. Harald Arend, head of the Guyana Space Center Soyuz program at the ESA, the agency funding the space project. The first launch is scheduled for late next year. H2O2 is used in the engines of the first two stages of the Soyuz rocket to force the actual fuels, kerosene and liquid oxygen, into the combustion chambers through turbo pumps.
H2O2 is one of the oldest products made by Degussa, yet also one of its most innovative. Degussa has an annual production capacity of approx., 600,000 tons of H2O2. It has production facilities in Germany, Belgium, Italy, Austria, the U.S., Canada, Brazil, Korea, Indonesia, New Zealand and South Africa. H2O2 is used for a very wide range of applications. The largest quantities are used in pulp bleaching, waste paper recycling and in manufacturing washing powders and liquids; the chemicals industry uses hydrogen peroxide as an oxidant. Other areas of use include pollution control, packaging disinfection and the treatment of waste water and drinking water. Sudden blondeness also indicates that hydrogen peroxide may have been at work. And, of course – bringing us back to the topic at hand – it is used in rocket engines.
Degussa—a wholly-owned subsidiary of the RAG Group—is the global market leader in specialty chemicals. Our business is “creating essentials”—innovative products and system solutions that make indispensable contributions to our customers’ success. In fiscal 2006, the company’s approximately 36,000 employees worldwide generated sales of 10.9 billion euros and operating profits (EBIT) of over 870 million euros.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
