Heteroepitaxial nucleation and growth of complex coatings at mineral/water interfaces

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Sebastien Kerisit

All realistic mineral surfaces in natural waters can be expected to be coated, and their reactive properties influenced by the presence of coatings. Heteroepitaxial growth is the templated growth of…

The Role of Interfacial Processes on Mineral Transformations in Wet Supercritical CO2

Lead Institution

Washington State University

Principal Investigator

Andrew Felmy

Project type

Large-Scale EMSL Research

We propose a comprehensive experimental and theoretical investigation of the role of interfacial water and CO2 on the energies, mechanisms, and rates of reactivity of a series of orthosilicate and…

Role of Microenvironments and Transition Zones in Subsurface Reactive Contaminant Transport

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

James McKinley

This is a renewal proposal for a previous collaborative effort between the PNNL Scientific Focus Area (SFA) and EMSL. The research proposed will resolve critical Hanford and basic subsurface science…

Understanding the effect of etching medium in tuning the surface polarity of silica nanoparticles for tuning the loading and release of anticancer drugs

Lead Institution

Environmental Molecular Sciences Laboratory

Principal Investigator

Mark Engelhard

Silica nanoparticles have traditionally been used in drug delivery owing to their easy synthesis, nearly inert behaviour and ability to tune its surfaces for attaching targeting moieties. Recently…
