Age-hardenable aluminum alloys used in aerospace structures are susceptible to environment assisted fatigue crack propagation (EFCP). There has been no controlled examination of thin film electrolyte, typically produced by atmospheric exposures, effects on EFCP or inhibition of such cracking. The goal of this research is to understand EFCP and inhibition for atmospheric conditions of important ...

Neurotransmitters and hormones are stored within secretory vesicles inside the cell and release their contents in a quantal event by fusion with the plasma membrane. We develop and fabricate microchip devices that we apply in cell experiments for electrochemical measurements of quantal release events from adrenal chromaffin cells. Surface patterned electrodes on transparent surfaces are applied...

This paper reports the impact of vias on the spatial distribution of temperature rise in metal lines and shows that the temperature is highly dependent on the via separation. A 3-D electro-thermal simulation methodology using a short-pulse stress is presented to evaluate interconnect design options from a thermal point of view. The simulation methodology has also been applied to quantify the us...
