Organic and Biological Chemistry of Nitrated Lipids

Living organisms are continually challenged by highly reactive oxygen species (ROS) and reactive nitrogen species (RNS). In many cases ROS and RNS are destructive, but in some cases their chemistry has been channeled into biologically useful purposes. Nitrated lipids are produced by the action of ROS/RNS on lipids--such lipids have rece...

Simultaneous Beta and Gamma Spectroscopy

Oregon State University is seeking a company interested in the manufacture and commercialization of a state-of-the-art radiation detection system for real-time and simultaneous spectroscopy of beta-particles and gamma-rays. The spectrometer has proven to be an effective tool for recording separate beta gamma-ray spectra from mixed radiation fie...

Shear-Force Ultrasonic Near-Field Microscope

The Shear-Force Ultrasonic Near-Field Microscope (SUNM) is a nanometrology tool for surface and subsurface materials characterization, including the dynamic behavior of fluid-like mesoscopic films confined between two sliding solid boundaries. By mechanically exciting the film and detecting the resulting sound emitted, the elastic properties of the...

Development of Boron-Nitrogen Heterocycles

The Liu research group is developing a number of B–N-containing heterocycles, namely 1,2-dihydro-1,2-azaborines. These are structures that are isoelectronic and isostructural to benzene. Benzene, the epitome of aromatic compounds, has played a pivotal role in our fundamental understanding of the concept of aromaticity. The aim is to explo...

Heterometallic Group 13 Keggin-like Nanoclusters

The Johnson research group has developed a high-yielding synthetic strategy for preparing discrete polynuclear inorganic clusters containing thirteen Group 13 metals (Al, Ga, In) in a Keggin-like structure. Seven of the metal ions comprise the interior core, arranged in a flat hexagonal disc and bridged by hydroxo ligands. The remaining six m...

Ultra-Sensitive Optical Sampling by Coherent-Linear Detection

This new approach to optical waveform measurement is based on linear optical sampling: a short optical pulse provides the gating function and the sampling is accomplished using coherent homodyne mixing on a low speed photodetector, a linear optical process. The phase sensitivity inherent to homodyne detection is removed by simultaneous measure...
