Dimitri Mendeleev, a Russian, and Lothar Meyer, a German, published early versions of periodic tables in 1869 and 1870, respectively. Well, roll over, Mendeleev, tell Meyer the news: Washington Universitys Katharina Lodders has developed an innovative periodic table, slanted toward astronomy, thats definitely not your fathers periodic table.

Revised periodic table slanted toward astronomers
The periodic table isn’t what it used to be, thanks to innovations by a planetary chemist at Washington University in St. Louis.
Katharina Lodders, Ph.D., Washington University research associate professor in Earth and Planetary Sciences in Arts & Sciences, has evalutated data from numerous studies including her own and arranged the data into a periodic table slanted toward astronomers and cosmochemists. It’s the Cosmochemical Periodic Table of the Elements in the Solar System. Instead of atomic number, atomic weights, and melting- and boiling points, for example, Lodders provides elemental abundances and condensation temperatures. And it’s color-coded to indicate host phases of the elements - the phase where the element condenses into metal, sulfide, or silicate rock.

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...
