Heterogeneous graphs organize data with nodes and edges, and have been widely used in various graph-centric applications.

Heterogeneous catalysis is a type of catalysis in which the catalyst occupies a different phase from the reactants and products. This may refer to the physical phase — solid, liquid or gas — but also ...

Homogeneous catalysis is a type of catalysis in which the catalyst operates in the same phase as the reactants — usually dissolved in a solvent. Mechanistic studies of homogeneous catalysts are ...
