The results are directly relevant for understanding the interactions and the effects of particulate matter on pulmonary structures which could lead to pulmonary surfactant inhibition or deficiency causing severe respiratory distress or pathologies.
These particles of micro and nanometric sizes, which are released in the environment, have different surface areas and different surface chemistry, which mean different biological reactivity in their contact with the human body.
The pulmonary surfactant is a complex structure composed mainly from phospholipids (~90%) [8] that is essential for the normal respiratory function, lowering the surface tension during breathing by forming surface-active films at the air-liquid interface.
Thus, the use of model particles with decoupled parameters in term of size, surface chemistry… it is highly necessary in order to identify the origins and type of these interactions.
Conclusions Using a biomimetic pulmonary surfactant we have investigated the influence of surface charge of particles on adhesion force between particles and lipid structures and the effects on surface elasticity.

How the addition of these trace elements influence the growth characteristics and chemistry of the Al melt is also presented in this work.
Changing the chemistry of the Al melt through adding trace elements, can effectively react with Fe, changing the growth hillocks of the Fe IMC.
The light microscope polarized light revealed a colour disparity in grain structures and projected the natural lustre of dendrites.
Equiaxed grain structures are present in both alloys, but further refinement is ostensible in alloy II due to the addition of Mn and TiB2.
The α-Al grows as dendritic structures and continuous growth of α-Al causes Fe atoms to reject from the tips of dendrites, ahead of the solid liquid interface.
