Dust charging and mobilization is demonstrated in three experiments with exposure to thermal plasma with beam electrons, beam electrons only, or ultraviolet (UV) radiation only. These experiments present the advanced understanding of electrostatic dust transport and its role in shaping the surfaces of airless planetary bodies.

We present a technique to achieve low-velocity to intermediate-velocity collisions between fragile dust aggregates in the laboratory. For this purpose, two vacuum drop-tower setups have been developed that allow collision velocities between <0.01 and ~10 m/sec. The collision events are recorded by high-speed imaging.

The electrophoretic mobility shift assay (EMSA) is a biochemical procedure used to elucidate binding between proteins and nucleic acids. In this assay a radiolabeled nucleic acid and test protein are mixed. Binding is determined via gel electrophoresis which separates components based on mass, charge, and conformation. This video shows the concepts of EMSA and a general procedure, including gel and protein preparation, binding, electrophoresis, and detection. Applications covered in this video...

Brands must adjust their strategies to engage users where they spend most of their time, which is on mobile screens. Understanding mobile user behavior is crucial for successful mobile marketing. Mobile users typically interact with their devices briefly and frequently throughout the day. They prefer content that is...
FAQs
Particle movement begins when wind stress exceeds the threshold imposed by the soil or sediment surface. Below that level, loose mineral grains remain in place; above it, entrainment can occur and dust emissions increase. This threshold provides a basis for interpreting when erosion begins and for comparing the susceptibility of different environmental surfaces.
Saltation and suspension describe different particle behaviors after entrainment. Larger grains move through repeated hopping, while finer particles are lifted and maintained in the air by turbulence. Their contrasting movement affects how far material travels: saltating grains contribute to near-surface transport, whereas suspended particles can remain airborne and influence distant locations.
Turbulence helps keep fine mineral particles suspended after they leave the surface. Because these particles can travel long distances, their effects are not limited to the original erosion site. This atmospheric transport connects source regions with downwind changes in air quality, visibility, pollutant distribution, ecosystems, and climate-related processes.
Environmental investigations commonly examine dust flux, source regions, and atmospheric loading. Dust flux indicates the amount of material leaving a surface, source analysis identifies where particles originate, and atmospheric loading describes the quantity present in the air. Together, these measurements help connect surface erosion with downwind environmental effects.
Researchers can relate atmospheric dust loading to changes in air quality and visibility reduction. Tracking the amount of mineral material in the atmosphere helps indicate how strongly surface emissions affect atmospheric conditions, while identifying source regions clarifies where those effects begin. This information supports environmental assessment of both local erosion and transported dust.
Dust transport links exposed soils and sediments with downwind ecosystems and the broader climate system. Mobilized mineral particles can participate in biogeochemical cycling, carry pollutants through the atmosphere, and contribute to climate effects. Studying flux, origins, and atmospheric loading therefore helps explain how surface erosion produces consequences beyond the immediate source area.
