Nanoparticle Aggregation: Challenges to Understanding Transport and Reactivity in the Environment
TL;DR: This review briefly covers aggregation theory focusing on Derjaguin-Landau-Verwey-Overbeak (DLVO)-based models most commonly used to describe the thermodynamic interactions between two particles in a suspension.

Biomass combustion in fluidized bed boilers: Potential problems and remedies
TL;DR: In this article, the authors present the major issues concerned with biomass combustion with special reference to the small scale fluidized bed systems (small to pilot scale). Problems have been identified, mechanisms explained and solutions have been indicated.

Aerosol emission and superemission during human speech increase with voice loudness
Sima Asadi,Anthony S. Wexler,Christopher D. Cappa,Santiago Barreda,Nicole M. Bouvier,William D. Ristenpart +5 more
TL;DR: It is shown that the rate of particle emission during normal human speech is positively correlated with the loudness (amplitude) of vocalization, and the phenomenon of speech superemission cannot be fully explained either by the phonic structures or the amplitude of the speech.

Inhaled nanoparticles—A current review
TL;DR: The potential application of pulmonary drug delivery of nanoparticles to the lungs, specifically in context of published results reported on nanomaterials in environmental epidemiology and toxicology is reviewed in this paper.

The coronavirus pandemic and aerosols: Does COVID-19 transmit via expiratory particles?
TL;DR: As of late March 2020, the global COVID-19 pandemic caused by the SARS-CoV-2 virus has battered the world and more than 40,000 people have died with over 800,000People confirmed infected.

Deposition, retention, and clearance of inhaled particles
TL;DR: While the mechanisms and dynamics of particle deposition and clearance are reasonably well established in broad outline, reliable quantitative data are lacking in many specific areas.
Journal ArticleDOI
Experimental determination of the regional deposition of aerosol particles in the human respiratory tract.
TL;DR: The retention of the radioactive particles present in the body after aerosol administration is measured with a body counter designed and constructed for these experiments, and the elimination of material from the chest is found to be much slower for the material deposited in the alveolar region than for the amount deposit in the tracheobronchial tree.
Journal ArticleDOI
Ferromagnetic Contamination in the Lungs and Other Organs of the Human Body
TL;DR: The simplicity of detection of larger amounts of ferromagnetic contamination suggests that this method may be used in detecting the presence of large amounts of asbestos in the lungs of asbestos workers, and in tests of the condition of the lung where FE3O4 dust would be used as an inhaled tracer material.
Journal ArticleDOI
Total deposition of aerosol particles in the human respiratory tract for nose and mouth breathing
TL;DR: Whenever the mean residence time of the particles in the respiratory tract was short deposition for mouth-breathing was found to be almost independent of particle size in the diameter range below 1 μm revealing the significance of mixing.
Journal ArticleDOI
Long-term particle clearance in man: normal and impaired.
TL;DR: It is shown that long-term clearance is a well-defined physiological function characteristic of an individual and that smoking supressed the fast clearance phase and increased the half-time of the slow phase by 14.7% per pack-year of smoking.
