Nanoparticles can travel from lungs to blood, possibly explaining risks to heart

Apr 26 8:23am Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News
Tiny particles in air pollution have been associated with cardiovascular disease, which can lead to premature death. But how particles inhaled into the lungs can affect blood vessels and the heart has remained a mystery. Now, scientists have found evidence in human and animal studies that inhaled nanoparticles can travel from the lungs into the bloodstream, potentially explaining the link between air pollution and cardiovascular disease. Their results appear in the journal ACS Nano.

Defects in graphene enable selective permeability of gases

Apr 25 3:58am Nanowerk Nanotechnology News
Despite their potential, the practical use of Li-O2 batteries is seriously limited by the corrosion of Li metal by ambient water vapor from air. One way to circumvent this issue is to use an oxygen selective membrane that allows only oxygen into the battery while stopping or slowing water vapor intake. The membrane must be mechanically robust and yet sufficiently thin and light so as to not increase deadweight of the battery. Researchers now have discovered a way to make the thinnest possible oxygen selective membrane using graphene.
