Stöber Method to Amorphous Metal Organic Frameworks [PDF]
, 2023 The Stöber method is a widely-used sol-gel route for synthesizing amorphous SiO2 colloids and conformal coatings. Recently, further enrichment of this methodology has been achieved by extending it to other materials such as TiO2 and a resorcinol ...

Amorphous-amorphous transitions in granular packings
Nature CommunicationsAbstract Polyamorphs are the amorphous counterparts of the distinct crystalline phases that are found in the phase diagram of a substance. For a given system, polyamorphs have different local structures, resulting in distinct macroscopic properties, making them important for fundamental science and applications.
