The stability of agglomerates is not only an important material parameter of powders but also of interest for estimating the particle size upon accidental release into the atmosphere. This is especially important when the size of primary particles is well below the agglomerate size, which is usually the case when the size of primary particles is below 100 nm. During production or airborne transportation in pipes, high particle concentrations lead to particle coagulation and the formation of… 

Titre : Title : De-agglomeration of nanoparticles in a jet impactor-assisted fluidized bed Auteurs :

8 Nanoparticles in agglomerated state lose their outstanding properties; hence, it is essential to break them 9 up prior to use and prevent the re-agglomeration. Even though there are several dry

Deagglomeration testing of airborne nanoparticle agglomerates: Stability analysis under varied aerodynamic shear and relative humidity conditions

ABSTRACT Occupational exposure to nanomaterial aerosols poses potential health risks to workers at nanotechnology workplaces. Understanding the mechanical stability of airborne nanoparticle

Effect of particle agglomeration in nanotoxicology

The topic of this review is the role of agglomeration on toxicity, including the fate of nanomaterials after their release and the biological effects they may induce, and ENP uptake and intracellular distribution.

Minimum pickup velocity – the transition between nano-scale and micro-scale

The transport of nano-scale particles has become increasingly important, but the knowledge base available is limited. This study aims to bridge the knowledge gap between the nano- and micro-scales

Minimum pickup velocity (Upu) of nanoparticles in gas–solid pneumatic conveying

This paper is the first systematic study of the pneumatic conveying of nanoparticles. The minimum pickup velocity, Upu, of six nanoparticle species of different materials [i.e., silicon dioxide

Complex Aerosol Characterization by Scanning Electron Microscopy Coupled with Energy Dispersive X-ray Spectroscopy

The SEM/EDS analysis provides a more detailed physicochemical characterization of PM than online measurements, and has the potential to improve assessments of PM exposure and risk, and facilitates source identification, even without prior knowledge at sampling.

Dustiness and Deagglomeration Testing: Interlaboratory Comparison of Systems for Nanoparticle Powders

Different types of aerosolization and deagglomeration testing systems exist for studying the properties of nanomaterial powders and their aerosols. However, results are dependent on the specific

The Effect of Oxygen Precursor Concentration to the Iron Oxide Nanoparticles Properties for Lateral Flow Immunoassay Application

In this study, the influence of hydrogen peroxide (H2O2) concentration to the iron oxide nanoparticles (IONPs) properties prepared using the precipitation method was investigated. The H2O2



Impact Fragmentation of Metal Nanoparticle Agglomerates

Deagglomeration experiments were performed with agglomerates of nanoparticles of Ni and Pt. The fragmentation was induced by high velocity impaction of the agglomerates in a single‐stage low pressure

Gas-Phase Synthesis of Non-Agglomerated Nanoparticles by Fast Gasdynamic Heating and Cooling

A novel method for the production of oxide nanoparticles from gas-phase organic precursors in a high-velocity flow apparatus is described. In contrast to conventional methods of reaction initiation

Nanomaterials as Flow Regulators in Dry Powders

Abstract From a physical point of view powders represent an intermediary state between solids and fluids. This holds especially with respect to their flow properties. Gravitational forces as well as

Numerical simulation of the impact fracture and fragmentation of agglomerates

Computer simulations of agglomerates impacting a wall have been carried out using the distinct element method. The agglomerates comprised 1000 primary particles in a two-dimensional array.

Resuspension of Particles by Aerodynamic Deagglomeration

A deagglomerator system was developed, characterized by laboratory tests, and flown under low-gravity (low-g) microgravity conditions. Requirements for a dry powder deagglomeration system were

Capillary forces between two spheres with a fixed volume liquid bridge: theory and experiment.

Capillary forces are commonly encountered in nature because of the spontaneous condensation of liquid from surrounding vapor, leading to the formation of a liquid bridge. In most cases, the advent of
