Using a new type of nanoreactor, researchers at Chalmers University of Technology, Sweden, have succeeded in mapping catalytic reactions on individual metallic nanoparticles.
Their work could help improve chemical processes, and lead to better catalysts and more environmentally friendly chemical technology.
The results are published in the journal Nature Communications.
They are also essential building blocks for new, sustainable technologies like fuel cells, where electricity is generated through a reaction between oxygen and hydrogen.
The smoke spreads rapidly through the crowd, and once a smoke cloud has formed, it is almost impossible to say who actually lit the flares, or how powerfully each one is burning.
Millions of individual particles are involved, and it is currently very difficult to track and determine the roles of each specific one - how effective they are, how much each has contributed to the reaction.
