There’s nothing quite like going into the deep freeze to learn more about planet Earth.
That’s where Jihong Cole-Dai, assistant professor of chemistry and biochemistry at South Dakota State University, and graduate students Drew Budner and Dave Ferris will find themselves when they head to Antarctica in December.
In a collaborative research project with the University of California-San Diego and funded by the National Science Foundation, they will collect ice cores from the South Pole to examine the ice chemical composition that contains clues about the oxygen in Earth’s atmosphere. Cole-Dai’s research has centered on how volcanic eruptions during the last 1,000 years have affected the atmosphere. This new project expands on past research results. “We will again be looking at what happens to the atmosphere when volcanoes go off, but this time we want to find what happens to the oxygen chemistry,” said Cole-Dai.

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.
When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
