Nanosafety research – there’s room for improvement29 October 2014
The quest for the gold standard

Empa toxicologist Harald Krug has lambasted his colleagues in the journal Angewandte Chemie. He evaluated several thousand studies on the risks associated with nanoparticles and discovered no end of shortcomings: poorly prepared experiments and results that don’t carry any clout. Instead of merely leveling criticism, however, Empa is also developing new standards for such experiments within an international network.

Color trail shows quickest route to destination27 October 2014
A GPS from the chemistry set

Empa scientists teamed up with colleagues from Hungary, Japan and Scotland to develop a chemical “processor” which reliably shows the fastest way through a City maze. As the method is basically faster than a satnav system, it could be useful in transport planning and logistics in the future, for instance, as the scientists report in the journal Langmuir. 

Light sensitive membranes deliver medication23 October 2014
Gentle caffeine boost for premature babies

Empa researchers have developed a UV-activated membrane which releases a gentle dose of medication to the skin of a patient. In future those who fear injections will be able to sleep soundly, as will premature babies too, since the new dosing technique will spare them additional stress.

Focus: Atmospheric research - global and local

CFCs are still harming the ozone layer; industrial gases with a high greenhouse potential heat up the atmosphere. The polluters don't go undiscovered, though. Empa scientists are tracking the trace gases with highly sensitive instruments and identify the sources of pollution with the help of meteorological data. Focus-theme: atmospheric research.
