Digestive ripening process

C12H25LC12X), silanes (Ci8H37SiH3), and simple alkanes (CioH22). The experimental procedure for the digestive ripening process with different ligands is detailed below. 

Thus, we see that the digestive ripening process leads to highly monodispersed nanoparticles that can come together to form ordered superstructures similar to atoms or molecules that form crystals from a supersaturated solution. Then if the superstructure formation can indeed be related to atomic/molecular crystallization, it should also be possible to make these supercrystals more soluble in the solvent with a change of temperature. Indeed, the optical spectra of the three colloids prepared by the different thiols discussed above exhibit only the gold plasmon band at 80 °C suggesting the solubilization of these superlattices at the elevated temperatures [49]. 

In setting out this view, Albertus explicitly distanced himself from another position which, he said, was common among alchemists, particularly one Callisthenes . The alchemists position, as Albertus characterises it, supposes that one metal can transform into another one through a natural process of digestion and maturation beneath the earth. The least perfect metals gradually ripen into the more...
