Generating aerosol droplets via the atomization of thin aqueous films with high frequency surface acoustic waves (SAWs) offers several advantages over existing nebulization methods, particularly for pulmonary drug delivery, offering droplet sizes in the 1-5-μm range ideal for effective pulmonary therapy. Nevertheless, the physics underlying SAW atomization(More)
Amorphous silicon nitride is a model system for a covalently bound amorphous solid with a low atomic mobility where reasonable values of self-diffusivities are still lacking. We used neutron reflectometry on isotope enriched Si3 14N4/Si3 15N4 multilayers to determine nitrogen self-diffusivities ranging from 10(-24) to 10(-21) m2/s between 950 and 1250(More)
Different 2-Gbit and 4-Gbit DDR3 SDRAM devices have been tested. Under 60 Co, some of them showed a peculiar error pattern. Under heavy ions, none of the tested types displayed any latch-up. 2 I. INTRODUCTION SDRAM devices [1] are relevant for space applications – in particular for spacecrafts that will encounter a high total dose, like ESA's upcoming JUICE(More)
