Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Miao Song
Twin structures are widespread in natural and synthetic crystalline materials, leading to various structures and morphologies that significantly affect physical and chemical properties. However, the investigation of twin formation and evolution is...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: James De Yoreo
Using a combination of high-resolution and in situ TEM techniques, this work aims to develop an atomic-scale mechanistic understanding of anion exchange reactions and dopant migration in cesium lead halide perovskite nanocrystals. It will test the...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Feng Gao
To help meet DOE goals of enabling more fuel-efficient vehicle engine technologies, for the past ~15 years we have been carrying out research programs funded by DOE/Office of Energy Efficiency and Renewable Energy (EERE)/Vehicle Technologies Office...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Fan Mei
The vertical distribution of aerosol strongly influences the radiative forcing of the aerosols. However, observational data is limited. Both satellite observation and ground-based measurements are not able to provide well-resolved vertical profiles...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Arun Devaraj
This project will conduct a comprehensive demonstration of PNNL capabilities for multimodal in situ chemical imaging of structural, compositional and chemical state changes on metallic alloy surfaces during exposure to reactive gaseous environments...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Arun Devaraj
Solid phase processing (SPP) of alloys using shear-deformation results in nanoscale metastable phases and enhanced mechanical properties. High-speed mass and energy transfer during such process makes the atomic-scale mechanisms in solid phase...
Lead Institution: State University of New York at Stony Brook
Principal Investigator: Daniel Knopf
Atmospheric ice nucleation represents one of the least understood atmospheric processes, hampering prediction of cloud processes and climate. Whereas the aerosol community has widely conducted aerosol-cloud condensation nuclei studies to evaluate...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: James De Yoreo
The aims of the proposed research are to: 1) Determine the structure of the near surface water layer in the confined region between approaching mineral surfaces and determine the impact of electrolytes and bioorganic ligands on that structure, and 2...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Dongsheng Li
The long-term goal of this project is to understand the growth of complex crystalline structures by aggregation and oriented attachment (OA) of primary nanoparticles and thus to tune crystal structures with desired properties. The formation of...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Dongsheng Li
Electrical, optical and mechanical properties of inorganic nanostructures have strong relationships with their morphologies. For example, one-dimensional (1D) nanomaterials such as carbon nanotubes, ZnO nanowires, TiO2 nanotubes possess novel...
