Self-Healing Polymers Prevent Leakage of Lead from Solar Cells

A protective layer of epoxy resin helps prevent the leakage of pollutants from perovskite solar cells (PSCs), report scientists from the Okinawa Institute of Science and Technology Graduate University (Oist). Adding a “self-healing” polymer to the top of a PSC can radically reduce how much lead it discharges into the environment. This gives a strong boost to prospects for commercializing the technology.

Sharpest Images of Living Bacteria Reveal Possible Weak Spots

The sharpest images ever of living bacteria have been recorded by UCL researchers, revealing the complex architecture of the protective layer that surrounds many bacteria and makes them harder to be killed by antibiotics. The study reveals that bacteria with protective outer layers — called Gram-negative bacteria — may have stronger and weaker spots on their surface.
