Loofah-inspired aerogel efficiently filters microbes from water
2020年8月21日 · To help address this need, researchers have developed a strong, flexible filter out of a silica aerogel that efficiently kills bacteria, resists getting clogged, and needs just a quick dip in dilute bleach to renew its disinfecting properties (ACS Nano 2020, DOI: 10.1021/acsnano.0c03793).
Exploration of Ultralight Nanofiber Aerogels as Particle Filters ...
2018年2月26日 · Ultralight nanofiber aerogels (NFAs) or nanofiber sponges are a truly three-dimensional derivative of the intrinsically flat electrospun nanofiber mats or membranes (NFMs). Here we investigated the potential of such materials for particle or aerosol filtration because particle filtration is a major application of NFMs.
