中国学生发明了一种自我清洁的门把手，它是2019年詹姆斯·戴森奖的获奖作品之一

Some say that everything genius is actually simple. And they might be really onto something there because if you think about it for one second, most of the inventions used every day are quite basic. All it takes is a good idea and a bit of knowledge. That’s exactly what happened to these two teenagers. 17-year-old Sun Ming and 18-year-old King Pong were researching chemical properties of titanium dioxide when they realized it could be applied on such a basic item as a doorknob and it could actually change people’s lives.

有人说，一切天才其实都很简单。他们可能真的说到点子上了，因为如果你想一下，每天使用的大多数发明都是很基础的。它所需要的只是一个好主意和一点知识。这两个青少年就是这样。17岁的王森明和18岁的李建邦当时正在研究二氧化钛的化学性质，后来他们意识到二氧化钛可以应用在门把手这样的基本物件上，而且可以改变人们的生活。

This is not your ordinary door handle as it is able to sanitize itself with the help of light

这可不是普通的门把手，因为它可以在光线的帮助下自我清洁

Sum Ming Wong and Kin Pong Li discovered quite a while ago that titanium oxide is extremely effective in killing bacteria and came up with an idea to ground it into a fine powder. They also noticed that it works better when exposed to UV light. Thinking of how to get the most of their discoveries, one simple yet genius thing popped into their heads.

王森明和李建邦很久以前就发现氧化钛在杀灭细菌方面非常有效，于是他们想到了把氧化钛磨成细粉的办法。他们还注意到，当暴露在紫外线下时，效果更好。在思考如何获得最大的发现时，一个简单而天才的想法突然出现在他们的脑海里。

It was created by University of Hong Kong students, Sum Ming Wong and Kin Pong Li

它是由香港大学的学生王森明和李建邦发明的

Knowing door handles are one of the most bacteria-infected things in our civilization, they designed a handle that’s made of a comprised glass tube with little aluminum caps both on the top and bottom of it. The whole glass construction is covered with that same titanium dioxide powder.

他们知道门把手是人类文明中最容易感染细菌的东西之一，于是他们设计了一种门把手，这种门把手是由玻璃管组成的，门把手的顶部和底部都有小铝盖。整个玻璃结构覆盖着相同的二氧化钛粉末。

The door handle is covered in a photocatalytic coating, meaning its’ chemical abilities are triggered by light

门把手覆盖着一层光催化涂层，这意味着它的化学能力是由光触发的

The chemical reaction that is activated by UV light decomposes the bacteria collected on the doorknob

紫外线激活的化学反应会分解门把手上的细菌

They also say their main inspiration to seek out a similar invention came after the SARS (Severe acute respiratory syndrome) outbreak in 2003 that infected more than 8000 people all over the world and China in particular, where 700 people died.

他们还表示，他们寻找类似发明的主要灵感来自2003年的SARS(严重急性呼吸系统综合症)爆发，当时全球有8000多人感染了SARS，其中中国感染人数最多，死亡人数达700人。

This invention made it to the 2019 James Dyson Awards and was one of the winning entries
