一次性口罩既不经济也不环保？以色列理工学院的科研人员近日研发出新型的充电口罩，可使用手机充电器充电加热来杀死口罩上的病毒，以实现重复利用。 图片Israeli researchers say they have invented a reusable face mask that can kill the coronavirus with heat by drawing power from a mobile phone charger. 以色列研究人员称，他们已经发明了一种可重复使用的口罩，可以使用手机充电器充电加热来杀死新冠病毒。 The disinfecting process takes about 30 minutes - and users should not wear the mask while it is plugged in, said Professor Yair Ein-Eli, who led the research team at Technion University in Haifa. 该研究小组组长、位于海法的以色列理工学院的亚伊尔·埃因-埃里教授说，这种口罩消毒过程大约需要30分钟，使用者切勿在充电时佩戴。 The new mask has a USB port that connects to a power source such as a standard cellphone charger that heats an inner layer of carbon fibres to 70 degrees Celsius, high enough to kill viruses. 这种新型口罩有一个USB接口，可以连接到电源，比如标准的手机充电器。充电时口罩的内层碳纤维可加热到70摄氏度，足以杀死病毒。 Ein-Eli said disposable masks, in high demand globally during the health crisis, were not economically or environmentally friendly. |
