Wearing face masks has been widely recommended to contain respiratory virus diseases, yet the improper use of poses a threat jeopardizing protection effect. We here identified bacteria viability on common and found that majority (90%) remain alive after 8 h. Using laser-induced graphene (LIG), inhibition rate improves ∼81%. Combined with photothermal effect, 99.998% bacterial killing efficiency could be attained within 10 min. For aerosolized bacteria, LIG also showed superior antibacterial...
Abstract Support-induced strain engineering is useful for modulating the properties of two-dimensional materials. However, controlling planar molecules technically challenging due to their sub-2 nm lateral size. Additionally, effect on molecular remains poorly understood. Here we show that carbon nanotubes (CNTs) are ideal substrates inducing optimum through curvature. In a tandem-flow electrolyser with monodispersed cobalt phthalocyanine (CoPc) single-walled CNTs (CoPc/SWCNTs) CO 2...
