RUI: Bimolecular Collisions in Ionic Liquid

The primary goal of the proposed research is to study the bimolecular collisions between solute molecules in ionic liquids (ILs) employing nitroxide spin probes. Recently, we have developed a new spin probe electron paramagnetic resonance (EPR) Heisenberg spin exchange (HSE) technique that can separate the effects of dipole-dipole and spin exchange interactions on the EPR spectra in viscous media. This method can now measure the bimolecular collision...

MRI: Acquisition of an EPR Spectrometer for Research and Education

With this award from the Major Research Instrumentation Program (MRI) and support from the Chemistry Research Instrumentation Program (CRIF), Professor Miroslav Peric from California State University Northridge and colleagues Radha Ranganathan and Jussi Eloranta have acquired an X-band electron paramagnetic resonance (EPR) spectrometer. This instrument will allow research in a variety of fields such as those that provide insight o...

Interaction between Alzheimer's beta-Amyloid Peptide and Phospholipid Bilayers

Alzheimer's disease is characterized pathologically by abnormal depositions of ¤ amyloid proteins in the brain, called senile plaques. Unfortunately, the pathophysiological role of the ¤-amyloid peptides in causing Alzheimer's disease and how senile plaques affect the neuronal membrane is still unknown. Although many findings strongly indicate that the pathophysiological effects of amyloid plaques may partially be caus...
