Siemens is expanding its RFID product range, Simatic RF600, with new transponders that have considerably greater memory capacities and a compact mobile…

Dark matter is a transparent form of matter that makes up most of the mass in the universe. Because dark matter does not reflect, absorb, or emit light, it can…

The neutrino experiment formerly known as LBNE has transformed. Since January, its collaboration has gained about 50 new member institutions, elected two new…

Galaxies are constantly forming new stars within dense clouds of interstellar material. The star formation rate in today's galaxies is, however, much lower…

Luke Skywalker’s home in “Star Wars” is the desert planet Tatooine, with twin sunsets because it orbits two stars. So far, only uninhabitable gas-giant planets…

Based on a very thin, high-strength design of the invention the ultrasonic sensor is placed between the teeth of the approximal region, thus reducing the distance significantly. As a result the images posses a very high spatial resolution.
The ultrasonic sensor consists of a metallic base plate with a reinforced frame, made of high-strength pure titanium or a TiAl6V4 alloy. The edges of the frame are rounded to make the insertion in the approximal region more comfortable. The total thickness of the design is limited to a maximum of 0.8 mm. The piezoelectric part is made on a PVDF-film equipped with spacers and shielded by an adjustable cover. The cover allows for a special contact by respecting the safety clearance to the teeth. By removing the cover hydrogel is pumped into the gap to provide acoustic coupling. In addition, it is used for lubrication of the cover movement.

The present invention comprises a buffer memory for combined cycle (CC) power plants, which mitigates the effect of accelerated startup and shutdown of the gas turbine on the heat recovery steam generator. Hence, CC Power Plants are enabled to exploit the full potential of their gas turbines in the growing balancing power market without having to accept increased degradation of the waste heat boiler

In many materials, macroscopic magnetic properties emerge when microscopically small magnets align in a fixed pattern throughout the whole solid. In a…

Scientist at the Westfälische Wilhelms University of Münster developed the efficient Cu-catalyzed PEN method for the formation of tetra-substituted pyrazoles. In this atomeconomic process, readily available enamines and nitriles are reacted by C-C and N-N bond formation. A broad scope of enamines and nitriles can be utilized in this process.

Engineers at the University of California, San Diego, have developed a new family of methods to significantly increase the speed of time-resolved numerical…

Materials with a defined crystal structure are a familiar phenomenon in condensed matter physics. A crystal exhibits a regular structure, due to a periodic…

Quantum entanglement is always related to the microscopic world, but it also has striking macroscopic effects, such as the squeezing of light or…

Astronomers using observations from the NASA/ESA Hubble Space Telescope and NASA's Chandra X-ray Observatory have studied how dark matter in clusters of…

The fact that the neutron is slightly more massive than the proton is the reason why atomic nuclei have exactly those properties that make our world and…
