Dynamics of airflow in a short inhalation [PDF]
Journal of the Royal Society Interface, 2015 During a rapid inhalation, such as a sniff, the flow in the airways accelerates and decays quickly. The consequences for flow development and convective trans- port of an inhaled gas were investigated in a subject geometry extending from the nose to the bronchi.

Inhalation and deposition of spherical and pollen particles after middle turbinate resection in a human nasal cavity [PDF]
Respiratory Physiology & Neurobiology Volume 294, December 2021,
103769, 2021 Middle turbinate resection significantly alters the anatomy and redistributes the inhaled air. The superior half of the main nasal cavity is opened up, increasing accessibility to the region. This is expected to increase inhalation dosimetry to the region during exposure to airborne particles.

Relationship between Cytotoxicity and Surface Oxidation of Artificial Black Carbon
Nanomaterials, 2021 The lacking of laboratory black carbon (BC) samples have long challenged the corresponding toxicological research; furthermore, the toxicity tests of engineered carbon nanoparticles were unable to reflect atmospheric BC. As a simplified approach, we have
