This means that the bug sprays last longer, as they are protected from the strong rays of sunshine, reports Chemistry & Industry, the magazine of the SCI. This is becoming increasingly important as temperatures rise, with the Met Office announcing that several heat records were broken in the UK this year.
The team of scientists, led by Dr Li-Xiong Wen, has developed a new type of capsule that shields pesticides from UV light. The research, to be published on Monday in Pest Management Science (DOI 10.1002/ps.1301) shows that the pesticides can be exposed to sunlight for at least twice as long without degrading.
Dr Wen, of the Bejing University of Chemical Technology, believes that the pesticide will be more effective as a result, thereby reducing the amount required and the cost to the farmer. It could also mean cleaner waters, as the risks of excess pesticide contamination will be lowered.
“It can be used for many other pesticides. We are considering it as a platform carrier material for pesticides and have looked at several pesticides, including this oil-soluble avermectin, and water-soluble validamycin, and a couple of others, all demonstrating the same behaviors,” Wen said.

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.

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...
