Dual Satellite Coverage using Particle Swarm Optimization
A dual satellite system in a Low Earth Orbit, LEO, would be beneficial to study the electromagnetic occurrences in the magnetosphere and their contributions to the development of the aurora events in the Earth's lower atmosphere. An orbit configuration is sought that would increase the total time …

Electron acceleration and loss caused by wave-particle interactions in the Van Allen radiation belts
Modern society relies substantially on satellite technology as it is involved in vital services like telecommunication services, Earth observation, navigation, and many more. There are more than 1000 operational satellites in Earth orbit and most of these spend at least some of their time in the …

Controlling Plasmon Coupling in Biomolecule-Linked Nanoparticle Assemblies
… in ~100 nm assemblies composed of 13 nm gold "satellite" particles tethered by duplex DNA to a 50 nm gold "core" particle. Comparison of core-satellite assemblies formed with duplex DNA tethers of varying length demonstrates that, while core-satellite separation is controlled by the number of …
