Better multivalent battery materials through diffusion high-throughput computations
Accelerating the discovery of advanced materials is essential for human beings. However, the traditional trial-and-error way of developing materials is often very empirical and time- consuming. In 2011, the launch of Materials Genome Initiative marked a large-scale collaboration between computer …

Attractive electrostatic self-assembly of ordered and disordered heterogeneous colloids
Ionic colloidal crystals are here defined as multicomponent ordered colloidal structures stabilized by attractive electrostatic interactions. These crystals are colloidal analogues to ionic materials including zincblende, rocksalt, cesium chloride, and fluorite. A thermodynamic study revealed that …

Synthesis and application of ionic molecular and polymeric materials
Materials are built from atoms and molecules through different interactions. Few artificial material is built primarily with ionic interaction despite its ubiquitous existence in living systems. My research has focused on filling this void by developing novel ionic molecular and polymeric materials …

Mechanisms governing the growth, reactivity and stability of iron sulfides
The kinetics of electrochemical processes in ionic materials are fundamentally governed by dynamic events at the atomic scale, including point defect formation and migration, and molecular interactions at the surface. A corrosion system comprising an iron sulfide film (passive layer) formed on iron …

The colloid and surface chemistry of allophane
… It was generally greater for cations of greater ionic charge, radius, and ease of hydrolysis. The selectivity shown by allophane between any two cations was found to vary with pH; at low pH the more favoured ion was that with the larger radius and lower charge but with pH increase the selectivity …
