For shorter approval times: New process simulates decomposition of too long stored drugs in 15 minutes

New approach represents a paradigm shift in the application of mechanochemical processes in organic chemistry

31-May-2023

Before their approval, pharmaceuticals not only have to be tested for their effectiveness and safety, but also for their stability, since they are usually stored in pharmacies and private households for years and are not allowed to change. To test their stability, a process is needed that ...

Electronic noses sniff out volatile organic compounds

Improving the fluid flow inside noselike chambers can enhance detection of harmful chemicals

25-May-2023

Volatile organic compounds are chemicals emitted as gases that can have adverse health effects. They are often found in paints, pharmaceuticals, and refrigerants, among other common products, but they can also act as markers of explosives, insect infestation, food spoilage, and disease. Tracing ...
