21. Aerosol deposition to coastal forests: a wind tunnel approach
Sammanfattning : Aerodynamically rough surfaces of forests provide for efficient air/ canopy exchange of mass, heat and momentum. In that context, the effects of forest edges come into focus, and therefore, coastal-zone forests constitute aparticular concern. LÄS MER
22. Particle Deposition Studies in a Laminar Wall Jet - The Hydrodynamic Influence on the Kinetics of Colloidal Deposition
Sammanfattning : In the research area of cleaning and process hygiene it is important to understand the underlying mechanisms behind the deposition of particles and macromolecules onto surfaces. The deposition process is described as the transport of particles to the surface followed by attachment. LÄS MER
23. Synthesis, Electrophoretic Deposition, and Characterization of Nanostructured Thermoelectric Materials
Sammanfattning : The world’s increasing demand for energy and supplying this energy dominantlyfrom fossil fuels has a major impact on global climate change. Theenergy crisis has gotten more alarming in the recent years which increasedthe motivation for replacing fossil fuels with greener routes for energy harvest. LÄS MER
24. The influence of Al alloy microstructure on conversion coating formation
Sammanfattning : The formation of conversion coatings based on Ce, trivalent Cr and Ti/Zr is triggered by the local pH increase at cathodic IM sites of the aluminium alloy microstructure. The pH gradient is created over the cathodic intermetallic (IM) sites of the microstructure and its intensity is influenced by their activity which depends on their chemical composition, their size, and spatial distribution.

25. Impact of Surface Structures onDeposition and Erosion in a Tokamak
Sammanfattning : Fusion is a potentially unlimited and environmentally friendly energy source for human society in the future. However, along the way towards the application of fusion energy there are still unresolved complications. Among them, deposition and erosion are two critical issues. LÄS MER
