Mossbauer analysis for goethite reacted with Fe(II) and membrane fraction of Shewanella oneidensis

Lead Institution

Pennsylvania State University

Principal Investigator

Je-hun Jang

Project type

Exploratory Research

Based on literatures, we expect that goethite will transform, to some extent, into other iron minerals in the presence of Fe(II). We prepared goethite samples that were incubated with either Fe(II)…

Characterization of Quantum Cascade Lasers

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

James Kelly

Project type

Exploratory Research

We will use the moderate and hi-resolution Fourier transform infrared spectrometers located in EMSL 1130 to characterize several pulsed and cw, infrared quantum cascade lasers.

Chemically-selective Sensor Film Characterization

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Zheming Wang

Project type

Exploratory Research

A new film material comprised of quaternized poly(4-vinylpyridine) cross-linked with 1,10-diiododecane (herein QPVP) has been developed for possible use in the spectroelectrochemical sensor for…

Unraveling the Molecular Biology of Host-Pathogen Interactions

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Liang Shi

Project type

Exploratory Research

Macrophages play an important role in the pathogenesis of Salmonella infection. Critical to the ability of macrophages to kill the Salmonella is the activity of the divalent metal ion transporter…

Peptide Observation Model

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Lars Kangas

Project type

Exploratory Research

Washington State University (WSU) student Luning Wang will model the probability of peptides being identified in spectrometry as a part of PNNL's effort in increasing identification confidence…

Photoreflectivity in Ge/Si thin films

Lead Institution

Environmental Molecular Sciences Laboratory

Principal Investigator

Kenneth Beck

Project type

Exploratory Research

We are measuring the photoreflectivity at 750-800 nm in specially prepared Ge thin films deposited on Si/SiN substrates. The measurements will allow us to estimate the actual free carrier lifetime…
