They help to exhale oxygen and exhale wastegases (e.g. carbon dioxide). The volume of air carried by the lungs depends on various factors: bodysize, type of activity and state of health. The volume can be categorized as tidal, vital and residual. The Archimedes principle was used to ...

). These acquired pores evolved during reduction due to the net volume loss caused by the removal of oxygen. Thus, the HyDR product is also called sponge iron. The elemental maps probed by energy-dispersive X-ray spectroscopy (e.g., Si, Al, Ca, and Mg in Fig. ...
In simple words, an oxygen concentrator works on electricity; takes in room air, removes nitrogen from it and provides up to 95% pure oxygen.The composition of air (78% Nitrogen, 21% Oxygen and 1% other gases like Carbon Dioxide, Argon, etc.) clearly shows that air is mainly comprised ...
