Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Lance Hubbard
Overwhelmingly, betavoltaics’ (BV) long-lasting power opens a broad range of applications which are not currently available. The birth of very low power electronics has opened up a market for the wide and accepted use of BVs (US Patent: US9887018...
Lead Institution: Environmental Molecular Sciences Laboratory
Principal Investigator: James Evans
Subcellular structures and macromolecular complexes can be revealed through cryo electron tomography of whole cells. Pseudarthrobacter chlorophenolicus is a soil bacterium which has novel metabolic pathways that may give insight into drought...
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: Robert Dagle
The overall objective of this study is to investigate a recent catalyst innovation that enables the stable conversion of methane to CO2-free H2 and solid carbon. The solid carbon is selectively formed as carbon nanotubes (CNT) and carbon fibers (CF...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Robert Dagle
The overall objective of this study is to further investigate our recent catalyst innovation enabling the selective, single-step conversion of bio-derived ethanol to 1- and 2-butene (linear butenes). We intend to continue to improve the technology...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Sandra Taylor
The objective of this work is to elucidate atomic- to nano-scale mechanisms driving the evolution of materials in extreme environments, relevant to energy applications. Current understanding of the synergistic effects of variables such as high...
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: Pacific Northwest National Laboratory
Principal Investigator: Sebastien Kerisit
The presence of mineral surfaces and of microorganisms significantly impacts the nature and composition of mineral phases formed in biogeochemical systems. Despite the importance of these heterogeneous reactions, predictions of the fate of...
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...
