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 recen...

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 exploi...

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...

Substituted Tetrakis (Arylethynyl) Benzenes
Organic compounds possessing a high degree of conjugation are recognized as ideal materials for advanced electronic and photonic applications including organic LEDs, LCDs, thin film transistors, solar cells, and optical storage devices. Optical and physical properties of highly conjugated organic molecules can be altered by changing the subst...

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...
