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?
The contributions of continuous flow toward greener and more sustainable processes are various. The most striking impact is that efficiency can be maximized – be it in mass, energy, space, and time – due to the enhanced heat and mass transfer, precise residence time control, shorter process ...
In their most basic form, self-driving cars are being designed to avoid accidents if they can, and minimise speed at impact if they can't. Although, like humans, they aren't able to make a moral decision before an unavoidable accident. But self-driving cars will besafer than human driver...
