This chapter explores the mechanisms of particle deposition. The major mechanisms for particle deposition from suspension flowing through granular media are inertial impaction, interception, sedimentation, electrostatic forces, Brownian diffusion, and straining. In addition, deposition may also result from ...
First some basic aspects of the interaction of energetic particles with matter are introduced. For further details, the reader is referred to standard handbooks of nuclear physics [1–5].
Instead, a model based on the impact of a liquid droplet onto a surface has been used to correlate the experimental deposition efficiency with the Reynolds number (Re) of the MG particle before impact [17]. The Re is defined by the ratio between the inertial and viscous forces of MGs at...

deposition mechanismsfilter flow modelsSummary The removal of harmful aerosol from a gas by use of a filter is common practise and hence much work has been performed in understanding the efficiency with which particles are removed. Filters which consist of a mat of fibres in an open three-...
Although multiple molecules and factors promote systemic clearance of cell debris, the role of the cellular reticuloendothelial system in debris clearance cannot be overstated. A century ago, Aschoff introduced the concept of the reticuloendothelial system, outlining a principle of particle uptake and...
Polydopamine is a biomimetic self-adherent polymer, which can be easily deposited on a wide variety of materials but the polymerization mechanism and the key intermediate species formed during the deposition process are still controversial. Here, the authors report a systematic investigation of polydopami...
Particle deposition in the lung causes recruitment of inflammatory cells that generate ROS, clastogenic factors, and cytokines either harming or stimulating resident lung cells [31]. Inflammatory phagocytes are an important source of RNS/ROS generation within the lung. Owing to their inducible nitric ...
Finally, we find a relation of cleaning area vs. stand-off γ that deviates from literature data on surface erosion. This indicates that different effects are responsible for particle removal and for substrate damage. It is suggested that a trade-off of cleaning potential and damage risk for se...
investigations into the implications of large-angle collisions in the burning plasma have yielded several key findings, including an ignition moment promotion by ∼10ps, the presence of supra-thermal ions below an energy threshold, and approximately twice the expected deposition of α-particles ...
