Very many publications have appeared on immobilized palladium catalysts that were used for CC bond-forming reactions, such as Suzuki, Heck or Sonogashira reactions. These catalysts are invariably converted to nanoparticles after the first run. Although these catalysts can be reused, there is no ...
So quantum dots are nanoparticles? Yes. But not every nanoparticle is a quantum dot. Only some materials (such as semiconductors) will show quantum size effects in their electronic structure when they are made into nanoscale particles. Why did they win a Nobel? From a purely fundament...
There is, however, reason for hope. This week's talks at the United Nations aim tonegotiate a total ban on nuclear weapons. These talks are the first of their kind ever to take place at the UN. The aim is to stigmatise nuclear weapons, as with biological andchemical weapons. The ulti...
