Nucleation and Growth/Metallic nanoparticles
It is a reversible process where the particles can be redispersed by applying external power, such as ultrasounds or mechanical stirring.
What is agglomeration?
It is the continuous hydrolysis and condensation of –Si–O–Si– monomers assisted by a basic catalyst (e.g., ammonia).
What is the Stöber method?
It is a classical model that describes the nucleation and growth of nanoparticles.
What is the Lamer diagram?
It is a process to produce nanoparticles that needs high temperatures, reducing agents, capping agents (ligands), and metal precursors, which can be either injected or mixed at the beginning of the reaction.
What is chemical thermodecomposition?
It is the typical method to produce small gold nanoparticles, based on the reduction of gold salt assisted by citrate.
What is the Turkevich method?
It is a type of assymmetric silica nanoparticles that have two distinct ‘’faces’’ or sides with different properties
What is Janus nanoparticles?
It is a nanoparticle whose mirror image is not superimposable to it and therefore it presents specific properties.
What is a chiral metallic nanoparticle?
It is an aggregate of smaller nanoparticles that assembles together during the reaction process and exhibits properties of the forming units.
What is a cluster of nanoparticles?
It is a type of silica particle that grows in the presence of micelles, which enlarge the pore size compared to regular silica particles.
What is a mesoporous silica particle?
