Removing air pollution with nanogenerator-enhanced air filters

Nanowerk.com - 26 мая, 2017 - 14:28
Researchers have utilized a rotating triboelectric nanogenerator (R-TENG) to enhance a polyimide nanofiber air filter for particulate matter (PM) removal. The nanofiber filter exhibits high removal efficiency for the PM particles with diameter larger than 0.5 microns. When working with the R-TENG, the removal efficiency of the filter is enhanced, especially in the region with the diameter of the particles in the PM smaller than 100 nm. This work may propose an approach of air cleaning and haze management by introducing TENGs to the filters.

Dry/wet adhesive materials for wound care inspired by octopus suckers

Nanowerk.com - 25 мая, 2017 - 17:45
Inspired by octopus arms, researchers demonstrate an uncomplicated and scalable templating technology for fabricating nanosuckers on PDMS substrates, using a scalable spin-coating technology. As the nanosuckers are pressed against a substrate, the flexible nanosuckers confirm to the substrate and deform by releasing the internal air between nanosuckers and the substrate, forming a seal and generating an adhesion force. The nanosucker adhesion is maintained over multiple contact cycles on both wet and dry surfaces.
