We found a novel oscillating phenomenon associated with surface wetting during the vacuum deposition of an organic semiconductor (rubrene) on a liquid film (bis(2-ethylhexyl)sebacate, B2EHS). In-situ observations by an optical microscope revealed that the oscillation was associated with the growth

To evaluate the effects of lung disease on deposition of inhaled ultrafine particles (less than 0.1 micron diameter), we measured total respiratory tract deposition of nonhygroscopic particles of 0.02 to 0.24 micron in five subjects with obstructive lung disease and

In this paper, particle deposition in three idealized proximal lung bifurcation models with an idealized mouth-throat were investigated experimentally. These bifurcation models included (1) a small symmetric bifurcation, (2) an intermediate asymmetric bifurcation, and (3) a large symmetric bifurcation. An

The use of polyanion and polycation-sensitive membrane electrodes to detect five different preparations of fucoidan is described. Unlike linear polyanionic molecules previously measured with polymer membrane-based electrochemical sensors, fucoidans from marine brown algae are all highly branched, sulfated polysaccharides with

Theoretical models of particle deposition in the respiratory tract predict high fractional deposition for particles of less than 0.1 micron, but there are few confirming experimental data for those predictions. We have measured the deposition fraction of a nonhygroscopic aerosol
