Abstract The plasma diagnostics presented in this article target the plasma surrounding a spacecraft that is created by the electric thruster and its surface modifying effects. The diagnostic package includes a retarding potential analyzer, a plane L

Publikováno v: Particles in Contact ISBN: 9783030158989

This chapter presents the development of a Discrete Element Method (DEM) contact model for aggregated nanoparticles. Particle synthesis from the gas phase often results in nanoparticles with a primary particle diameter smaller than 20 nm. These parti

Publikováno v: Journal of colloid and interface science. 501

We demonstrate the electrostatic assembly of oppositely charged silica particles into an ensemble of well-defined core-satellite supraparticles, which are a type of patchy particle. To achieve controlled heteroaggregation, we used oppositely charged

Fundamental knowledge about the mechanisms of adhesion between oxide particles with diameters of few nanometers is impeded by the difficulties associated with direct measurements of contact forces at such a small size scale. Here we develop a strateg
