The role of biopolymers in controlling mineral nucleation pathways and aggregation kinetics

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

James De Yoreo

Biopolymers are one of the most important regulators in controlling crystallization processes. They guide nucleation and growth by binding ions and/or templating mineral interfaces and alter particle…

Programmable Synthesis of Structurally Diverse and Functional Biomimetic Materials from Sequence-defined Polymers

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Chunlong Chen

Programmable synthesis of functional nanomaterials with diverse morphologies and functionalities is challenging in terms of both the limited chemical systems accessible and a lack of understanding of…

Investigating the nucleation pathway of CeO2 nanoparticles using Cryo-TEM

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

James De Yoreo

CeO2 nanoparticles can form oxygen vacancies at the surface of the particles, reducing nearby Ce4+ to Ce3+. This defect chemistry makes them highly useful as antioxidants in biological tissues…
