Quantification of hydrogen – method that uses a flame ionization detector to dermine hydrogen

The Carl von Ossietzky University in Oldenburg, Germany, developed a method which markedly improved the quantitative determination of hydrogen. A so-called TPR is conducted by coupling a flame ionization detector (FID) to a methanizer. Adding a certain amount of carbon monoxide (CO) and an excess amount of hydrogen immediately upstream of the FID, CO will react with hydrogen to yield methane. Methane produces a FID signal which is proportional to the amount of hydrogen in the sample.

Bacterial survival strategy: Splitting into virulent and non-virulent subtypes

Researchers at the Hebrew University of Jerusalem have discovered a survival strategy that harmful bacteria can use to outsmart the human immune response,…

Scientists discover helium chemistry

Although helium is the second most-abundant element (after hydrogen) in the universe, it doesn't play well with others. It is a member of a family of seven…

Adjustable flaps for wind turbines

Researchers at the University of Oldenburg have developed a flap for wind turbine generators which is mounted parallel to the main rotor blade and is considerably smaller in its size and mass than the main blade. The core piece of the invention is the adjustable pitch of the flap. The flap's pitch as well as its distance to the main blade can be swiftly adjusted to actual wind variations by means of a control unit or adaptive mechanics, thus assuring an optimal airflow at the site of the main rotor. The flap adjustment unit is able to consider the position of the main blade, the actual rotor rotation speed, and the actual wind speed. A purely mechanical adaptive pitch adjustment is also in a state of planning.
