d-electron Driven Energetic Materials

Solid-state propellants are typically selected from electropositive metals which release enough combustion heat to reach new heights. The Yeung group will demonstrate that d-electrons can contribute to energetic performance through the concept of ‘overcoordination.’ This demonstrates that previously ignored transition metals can fuel humanity’s dream of climbing ever higher.

Solid State Chemistry of New Alloys

The Ages of humanity have been defined by the metals used. To further advance civilization, we need to design new metals. The Yeung group will apply our knowledge of solid state chemistry to understand why materials break, and design new materials capable of withstanding even greater forces than before.

High Entropy Alloying for Poison Resistant Heterogeneous Catalysts

The majority of modern conveniences (e.g. plastics) are prepared by catalysis. Unfortunately, many of these reactions require noble metals which readily deactivate in the presence of impurities. The Yeung group will enhance catalytic longevity through sterically shielded crystal motifs.
