This door handle kills germs
這樣的門把手能殺死細菌
Diseases spread in many ways. An infected person can cough or sneeze on someone nearby. Or, they can transfer germs through a handshake. But sometimes we pick up germs indirectly. A sick person might leave behind bacteria or viruses when they touch a doorknob, handrail, shopping cart handle or countertop. Anyone else who touches that surface may pick up the microbes. But what if those surfaces could disinfect themselves？
細菌能通過很多途徑傳播，一個被傳染的人咳嗽或者打噴嚏，然後傳染給附近的人。這些細菌會也通過握手進行傳播。但有些時候，我們總是間接地被傳染，比如說一個生病的人可能會通過門把手，欄杆，購物車把手或面板遺留下細菌或病毒，而其他人可能會通過接觸這些物體表面而染上細菌。但假如這些物體表面可以自清潔，那麼結果又是什麼樣的呢？
Two teens from Hong Kong asked themselves the same question. Now they've developed a door handle that can knock out germs on contact.
兩個來自香港的少年也同樣問了自己這個問題，現在他們研發了一種門把手，可以清除在接觸過程中產生的細菌。
The glow from this door handle activates a microbe-killing coating. That could help reduce the transmission of diseases from germy hands.
該門把手發出的光能激活殺死細菌的塗料，這樣就會大大減少因細菌手引起的細菌傳播
The concept is simple. Every time the door is opened, the movement creates power that triggers a germ-killing reaction on the handle. In lab tests, their system killed about 99.8 percent of the germs that they spread onto lab dishes coated with their material.
概念很簡單，每次當門打開時的運動會產生能量，這些能量觸發門把手上的殺死細菌反應。實驗室試驗中，這一系統消滅了約99.8%實驗室盤中的細菌，當然，這些盤中也塗有他們的材料。
Research by others has shown that door handles in public areas often host lots of bacteria and viruses, notes 17-year-old Sum Ming ("Simon") Wong. The tenth grader attends Church of Christ in China Tam Lee Lai Fun Memorial Secondary School in Tuen Mun, China. He and schoolmate Kin Pong ("Michael") Li, 18, wanted to design a coating for door handles that would be hostile to germs.
"其他人的研究發現公共場所的門把手上駐有大量細菌和病毒"，17歲的孫明說道。這個10年級的學生參加了中國香港屯門譚李麗芬紀念中學的中華基督教會，他和他的18歲同班同學金鵬一同設計了這種包衣，用在門把手上可以殺死細菌。
After doing some research, they learned that a mineral called titanium dioxide is known to kill bacteria. It's already used for other purposes in many products, from paints to sunscreens to edible puddings.
做過一些研究之後，他們發現一種叫二氧化鈦的礦物質可以殺死細菌。這種礦物質也用於其他許多產品上，如塗料，遮光劑，以及可實用布丁中等等。
