Metal-organic frameworks with photocatalytic bactericidal activity for integrated air cleaning
Nature Communications, 2019 Air filtration has become an essential need for passive pollution control. However, most of the commercial air purifiers rely on dense fibrous filters, which have good particulate matter (PM) removal capability but poor biocidal effect.

Cleaning interfaces in layered materials heterostructures [PDF]
Nature Communications, 2018 Heterostructures formed by stacking layered materials require atomically clean interfaces. However, contaminants are usually trapped between the layers, aggregating into randomly located blisters, incompatible with scalable fabrication processes. Here we
