F Region Dusk Ion Temperature Spikes at the Equatorward Edge of the High-Latitude Convection Pattern
Using Poker Flat Incoherent Scatter Radar data from the International Polar Year, we observed unexpected short-lived enhancements of a few 100 K in the F region ion temperature, or “Ti spikes”, in conjunction with…

Horizontal Parameters of Daytime Thermospheric Gravity Waves and E Region Neutral Winds over Puerto Rico
We report on the electron density perturbation amplitudes, periods (up to 60 min), horizontal and vertical wavelengths, phase speeds, and propagation directions of daytime traveling ionospheric disturbances (TIDs) from 115…

Kinetics of light induced defect creation in organic solar cells
The kinetics of light-induced recombination centers are measured in bulk heterojunction organic solar cells, as a function of exposure time, intensity and the illumination photon energy.

Radiation induced hydrogen rearrangement in poly(3-alkylthiophene)
We present density functional calculations of the energy barriers that must be surmounted to form hydrogen related defects in polymers such as poly(3-alkylthiophene).
