Combined microscopy technique catches light-driven polymers in the act      (via sciencedaily.com)     Original source 

Researchers have used tip-scan high-speed atomic force microscopy combined with an optical microscope to observe light-induced deformation of azo-polymer films. The process could be followed in real time, and the film patterns were found to change with the polarization of the light source. The observations will contribute to the use of azo-polymers in applications such as optical data storage, and the approach is expected to be useful across materials science and physical chemistry.

Researchers improve the stability of perovskite solar cells      (via sciencedaily.com)     Original source 

Perovskite solar cells are considered the strongest contender to replace silicon solar cells. While they achieve high power conversion energy, they also suffer from lead leakage and perovskite degradation due to moisture. Now scientists leverage the technique of interfacial passivation, where lead ions are bound by crown ether B18C6, obtaining 21.7% power conversion energy. The crown ether also resists degradation due to moisture for 300 hours at room temperature and 85% humidity.

Want fewer microplastics in your tap water? Try boiling it first      (via sciencedaily.com)     Original source 

Nano- and microplastics are seemingly everywhere -- water, soil and the air. While many creative strategies have been attempted to get rid of these plastic bits, one unexpectedly effective solution for cleaning up drinking water, specifically, might be as simple as brewing a cup of tea or coffee. Boiling and filtering calcium-containing tap water could help remove nearly 90% of the nano- and microplastics present.

Nanocarrier with escape reflex      (via sciencedaily.com)     Original source 

Protein-based drugs must be transported into cells in a way that prevents their immediate degradation. A new approach is intended to ensure that they remain intact only in certain cells, such as cancer cells. A Japanese research team has introduced a nanocarrier that can 'escape' from endosomes before its cargo is destroyed there. This ability to escape is only triggered within the endosomes of certain tumor cells.
