Abstract:

La mesure de distribution de taille d’un aérosol (particules solides ou liquides en suspension dans un gaz) par analyse de mobilité électrique nécessite de neutraliser l’aérosol. La neutralisation consiste à conférer une distribution de charge centrée sur zéro obtenue par la diffusion sur l’aérosol d’ions bipolaires. Nous avons démontré la faisabilité d’un chargeur bipolaire post-Décharge à Barrières Diélectriques (DBD) pour remplacer les neutraliseurs radioactifs, généralement utilisées pour la production d’ions bipolaires et soumis à des contraintes législatives. La caractérisation électriqu

Abstract:

Dry powders for inhalation, although clinically effective, tend to be inefficient in terms of the extent and reproducibility of drug delivery. In part at least this is due to an inadequate understanding of the relevant particle-particle interactions between drug and drug, and drug and carrier. Electrostatic charge interactions are one of several factors influencing the overall efficiency of an inhalation powder. The practical significance of such interactions is considered to be critical in every aspect of the powder formulation, including the formation of an ordered mix and, more importantly,

Abstract:

Several theoretical and experimental studies of charged aerosol deposition in human airways have been reported. These studies suggest that higher charge values on particles lead to improve deposition efficiency in the human lung, especially in the alveolar region. Most of the previous numerical studies in realistic 3D geometrical models have been investigated only for uncharged particles. Hence, this research was aimed at numerically investigating aerosol transport and deposition by including the effect of electrostatic forces (both space and image charge forces).

The administration of pharmaceutical aerosols to infants on mechanical ventilation needs to be improved by increasing the efficiency of delivery devices and creating better ways of evaluating potential therapies. Aerosolized medicines such as surfactants have been administered to ventilated infants with mixed results, but studies have shown improvement in respiratory function with a much lower dose than with liquid instillation through an endotracheal tube (ETT). An aerosolized medicine must be transported through the ventilation tubing and deposit in the lungs to have the desired therapeuti

Abstract:

The electrostatic charge and size distribution of aerosol particles play a very important role in many industrial applications. Due to the complexity and the probabilistic nature of the different charging mechanisms often acting simultaneously, it is difficult to theoretically predict the charge distribution of aerosol particles or even estimate the relative effect of the different mechanisms. Therefore, it is necessary to measure the size and also the bipolar charge distribution on aerosol particles. The main aim of this research project was to design, implement and simulate a signal processi

Abstract:

Electrostatic properties of formulation component materials and blends play an important role in dry powder inhalation (DPI) products, and that valid measurement of charge distribution will lead to more precise control of powder behavior in DPI manufacturing processes. Ultra-fine powders are known to be bipolarly charged, have non-spherical shapes and tend to be highly cohesive. Real time, non-invasive techniques need to be developed to obtain a precise and accurate time-history characteristic of electrically charged powders as they aerosolize from a DPI product, and how this measure relates t

Abstract:

Oxidation flow reactors (OFRs) using low-pressure Hg lamp emission at 185 and 254 nm produce OH radicals efficiently and are widely used in atmospheric chemistry and other fields. However, knowledge of detailed OFR chemistry is limited, allowing speculation in the literature about whether some non-OH reactants, including several not relevant for tropospheric chemistry, may play an important role in these OFRs. These non-OH reactants are UV radiation, O(<sup>1</sup>D), O(<sup>3</sup>P), and O<sub>3</sub>. In this study, we investigate the relative importance of other reactants to OH for the fat
