Molecular capsules: Glowing with promise

Fluorescence has widespread applications, helping researchers to understand issues in the fundamental sciences and develop practical materials and devices. Among the useful fluorescent compounds in development, capsule-shaped molecular architectures, which possess both strong fluorescent properties and a nanometer-sized cavity, are particularly promising.

The image shows calibrated radiances produced by RAL Space for the shortwave (SW) channel which measures reflected sunlight and its total channel sensitive to all outgoing energy from thermal emissions by the earth and reflected sunlight. These observations allow reflected shortwave and emitted long-wave fluxes to be calculated that are then used by scientists for studying climate.

Joining the Un-Joinable: New polymer linking technology based on nano crystals developed in Kiel

Ever tried to paint on top of silicone? After a few hours, the paint will peel off. Annoying. Silicone is a so-called low surface energy polymer, well known from flexible baking forms: A synthetic material that has an extremely low adhesion or "stickiness". Teflon is similarly non-sticky and well known from frying pans. Researchers of Kiel University (Germany) have now developed the first technology which is capable of joining these two "unjoinable" materials. The technology applies passive nano-scaled crystal linkers as internal staples. The nano staples open up solutions to a large number of technical challenges, for example in medical engineering.
