Hydronium Hydroxide at Platinum Interfaces

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
James Cowin
Project type
Large-Scale EMSL Research
Hydronium hydroxide is in principle a very high-energy form of water. Normally it is considered too unstable to exist. Recent work at PNNL finds a particularly stable form of water adsorbed on a…

High-Resolution 27Al and 133Cs NMR of Weathered Hanford Sediments

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Karl Mueller
Project type
Large-Scale EMSL Research
Hanford vadose zone sediments (Hanford coarse, Hanford fine, and Ringold silt) have been weathered by reaction with a simulated Hanford tank waste leachate and examined with a wide array of…

Degradation of Lignin Using Homogeneous Catalysis in Ionic Liquids

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Zongchao Zhang
Project type
Large-Scale EMSL Research
The objective of the proposed work is to use ionic liquids as a reaction medium for homogeneous catalysis of the lignin degradation process, using weak-base organic catalysts that are soluble in…

Analysis of Self-Assembled Monolayers on Mesoporous Supports (SAMMS) Materials

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
John Bays
Project type
Large-Scale EMSL Research
The ability of self-assembled monolayers on mesoporous silica (SAMMS) to serve as a support for interfacial chemistry has been thoroughly proven by researchers at PNNL and other institutions. We…

Ice Nucleation on Aged Field Aerosols

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
James Cowin
Project type
Large-Scale EMSL Research
The number, density, and lifetime of clouds are strongly dependent on the kind of aerosol particles that are present, that act as "cloud nucleation centers" (CNC). This is one of the major…

Characterization of protein confinement in functionalized nanoporous supports

Lead Institution
Guilin University of Technology
Principal Investigator
Chenghong Lei
Project type
Large-Scale EMSL Research
One of the key fundamental scientific questions is how isolated proteins maintain their native active conformations in solution or in immobilization matrix. Molecular crowding and confinement theory…

MRI of chronic obstructive pulmonary disease

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Kevin Minard
Project type
Large-Scale EMSL Research
Proposed work will be performed using normal rats and emphysematous counterparts. The specific aims are to - 1) quantify regional alveolar airway destruction in vivo using 19F gas MRI techniques…

COMBINED NMR/OPTICAL MICROSCOPY OF BIOFILM PHYSIOLOGY STUDIES

Lead Institution
Washington State University
Principal Investigator
Paul Majors
Project type
Large-Scale EMSL Research
Bacterial biofilms are found nearly everywhere in nature. Microbial metabolism and phenotype vary rapidly within a biofilm - this is at least partly responsible for their metabolic diversity and…

Bradley Tebo's Proposal

Lead Institution
University of Washington
Principal Investigator
Bradley Tebo
Project type
Large-Scale EMSL Research
Mn oxides are important mineral phases in a variety of environments and have potential application in solar energy capture and conversion and contaminant remediation technologies. In nature,…

Integrated Experimental and Modeling Studies on Aerosol Evolution and Aging

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Rahul Zaveri
Project type
Large-Scale EMSL Research
The objectives of this project are to characterize the time evolution of aerosol size, density, composition, and mixing state in an aerosol chamber, and b) link experiments to the development and…

Ionic Transport of Hydrogen in Structured Soft Materials

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
James Cowin
Project type
Large-Scale EMSL Research
We will explore how the motion of hydrogen in the form of hydronium is controlled in a nanometer-sculpted multilayer composite water/hydrocarbon film, and how the motion of the ion alters the…

Imaging Of Water and Gas Distribution in PEM Fuel Cell Stacks and Cells

Lead Institution
Pacific Northwest National Laboratory
