When amazing new computers and other electronic devices emerge, they will have been conceived and incubated in university laboratories like that of Dr. Chris Gorman, professor of chemistry at North Carolina State University. There, the scientist and his multidisciplinary team are working to build, molecule by molecule, a nanoscale transistor.

created and visualized using scanning tunneling microscopy like that used to help create the nanoscale transistor.

That’s an electronic switch so small it can only be seen with a high-tech device called a scanning tunneling microscope. And if you go to the library to find the “how-to” book, says Gorman, “most of the pages will be blank, because nobody yet knows how to do it.”
And that, for the chemists, engineers and students engaged in the project, is what makes their painstaking, pioneering research so satisfying. If they can design and construct a nanoscale transistor, Gorman, his colleagues and his students will have filled in many of the blank pages in the how-to book. The field is so new, the research avenues so unexplored, that each experiment, each variation, helps write that book.

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...
