University of North Carolina at Chapel Hill chemists have developed what they believe is a breakthrough method of creating the world’s tiniest manufactured particles for delivering drugs and other organic materials into the human body.
Adapting technology pioneered by the electronics industry in fabricating transistors, the team has figured out for the first time how to create particles for carrying genetic material, pharmaceuticals and other compounds of unprecedented small size and uniformity. The tiny bits are so small they can be designed and constructed to measure only a hundred nanometers or so in diameter. A nanometer is a billionth of a meter.
Leading the group is Dr. Joseph M. DeSimone, William R. Kenan Jr. Distinguished professor of chemistry and chemical engineering at UNC and N.C. State University. A member of the UNC College of Arts and Sciences and the National Academy of Engineering, DeSimone also directs the National Science Foundation Science and Technology Center for Environmentally Responsible Solvents and Processes and the Institute for Advanced Materials, Nanoscience and Technology at UNC.

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...
