Uniform analyses for clean drinking water in Europe

PTB scientists receive award for concept of comparability and traceability of water analyses

14-Dec-2009

Clean water is a matter of survival for humans, particularly when it is used for drinking, cooking and for food manufacture. Therefore, the EU member countries have in several guidelines undertaken to guarantee their citizens sustainable clean drinking water. The requirement for this is, however, ...

More protection against explosives and nuclear material in freight containers

13-May-2009

Illegally transported, conventional explosives and nuclearly relevant or radioactive ma-terials can enable international terror organizations to transport hazardous materials for attacks to any place in the world. For improved protection against such hazardous freight, scientists of the ...

Magnetic nanoparticles navigate therapeutic genes through the body

PTB measures the pinpointed transport of therapeutics for cardiovascular diseases

09-Mar-2009

Health professionals send genes and healthy cells on their way through the bloodstream so that they can, for example, repair tissue damage to arteries. But do they reach their destination in sufficient quantities? Scientists of the PTB have developed a highly sensitive measuring method with which ...

Spin-polarized electrons on demand

With a single electron pump, PTB researchers provide 'counted' electrons with the desired spin

20-Jan-2009

Many hopes are pinned on spintronics. In the future it could replace electronics, which in the race to produce increasingly rapid computer components, must at sometime reach its limits. Different from electronics, where whole electrons are moved, here it is a matter of manipulating a certain ...

Checking people at airports with terahertz radiation

PTB succeeds in absolute measurement of terahertz radiation

22-Sep-2008

Within the last few years the number of transport checks – above all at airports – has been increased considerably. A worthwhile effort as, after all, it concerns the protection of passengers. Possibilities for new and safe methods of transport checks are offered by terahertz radiation. Before ...

Radioactivity: Discover the lowest amounts with new methods

18-Sep-2008

Detecting ever lower amounts of ionising radiation with ever better methods – scientists have had this goal since the start of the nuclear age. In addition to natural radiation, mankind is exposed to a multitude of other sources of radiation which result from the military and technical use of ...

PTB testing method for finger ring dosemeters has proven its effectiveness

24-Jun-2008

Finger ring dosemeters are used at diverse workplaces having ionizing radiation, e.g. in medicine and industry, in order to check whether the effective dose limt values are adhered to. The dosemeters used to measure beta radiation have been subjected to an annual quality control by the PTB for ...

Optical Atomic Clock: A long look at the captured atoms

On the way to the next generation of atomic clocks

07-Feb-2008

Optical clocks might become the atomic clocks of the future. Their "pendulum", i.e. the regular oscillation process which each clock needs, is an oscillation in the range of the visible light. As its frequency is higher than that of the microwave oscillations of the cesium atomic clocks, ...
