MASKS 1

Caption

Scanning electron microscope images by Rice University engineers show the effects of heat on the filter layer of a surgical facemask. The center image shows the polymer filter after decontamination at 70 degrees Celsius for 30 minutes. The right image shows the melted layer after exposure to 160 C for two minutes. The research team determined that a disposable mask can be decontaminated for reuse after five minutes at 70 C.
