一次性口罩既不經(jīng)濟(jì)也不環(huán)保？以色列理工學(xué)院的科研人員近日研發(fā)出新型的充電口罩，可使用手機(jī)充電器充電加熱來(lái)殺死口罩上的病毒，以實(shí)現(xiàn)重復(fù)利用。

以色列研究人員稱，他們已經(jīng)發(fā)明了一種可重復(fù)使用的口罩，可以使用手機(jī)充電器充電加熱來(lái)殺死新冠病毒。

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.

該研究小組組長(zhǎng)、位于海法的以色列理工學(xué)院的亞伊爾·埃因-埃里教授說(shuō)，這種口罩消毒過(guò)程大約需要30分鐘，使用者切勿在充電時(shí)佩戴。

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.

這種新型口罩有一個(gè)USB接口，可以連接到電源，比如標(biāo)準(zhǔn)的手機(jī)充電器。充電時(shí)口罩的內(nèi)層碳纖維可加熱到70攝氏度，足以殺死病毒。

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.

埃因-埃里稱，在健康危機(jī)期間全球需求旺盛的一次性口罩既不經(jīng)濟(jì)也不環(huán)保。

Ein-Eli said disposable masks, in high demand globally during the health crisis, were not economically or environmentally friendly.

他說(shuō)：“口罩最好可以重復(fù)使用，并且環(huán)保，而這款口罩就是我們的解決方案。”

“You have to make it reusable and friendly, and this is our solution,” he said.

耶路撒冷哈大沙醫(yī)療中心的傳染病專家阿龍·摩西教授說(shuō)，毫無(wú)疑問(wèn)，在70攝氏度的高溫下暴露半小時(shí)就會(huì)殺死新冠病毒。

Professor Allon Moses, an infectious diseases expert at Jerusalem’s Hadassah Medical Center, said there was “no question” that a half hour’s exposure to 70-degree heat would kill the coronavirus.

但他警告說(shuō)，反復(fù)加熱可能會(huì)“損壞口罩的材料或織物，并破壞其未來(lái)預(yù)防疾病的能力”。

But he cautioned that repeated heating could “damage the mask’s paper or fabric and spoil its ability to protect from diseases in the future”.

埃因-埃里說(shuō)，在測(cè)試過(guò)程中，原型口罩被加熱了20次，每次加熱半小時(shí)，其耐久性未受影響。

During testing, the prototype was exposed to 20 heating cycles, each for half an hour, with no impact on durability, Ein-Eli said.

他補(bǔ)充說(shuō)：“我們可以保證它可以重復(fù)使用幾十次，沒(méi)有任何風(fēng)險(xiǎn)。”

“We can guarantee it up to a few dozen cycles, without any risk,” he added.

這個(gè)原型口罩外觀類似于標(biāo)準(zhǔn)的N95口罩，前面有一個(gè)呼吸閥，并用帶子固定在頭部。

The prototype looks like a standard N95 face mask, with a valve at the front and bands to hold it in place around the head.

研究人員于3月下旬在美國(guó)為這種口罩申請(qǐng)了專利，并表示他們正在與私有企業(yè)討論商業(yè)化生產(chǎn)。

The researchers submitted a patent for the mask in the United States in late March and say they are discussing commercializing the product with the private sector.

研究人員稱，這種口罩的售價(jià)可能比普通的一次性口罩高出1美元（約合人民幣7元）。

It will likely sell at a $1 premium over the price of a typical disposable face mask, the researchers say.
