inventing a new battery. But as they experimented, Thai discovered something that might permit lithium-ion(锂离子)batteries to last forever.
Lithium-ion batteries power most wireless devices. Over time, the batteries lose the ability to hold a charge. Most of these batteries have a life span of about 7, 000 charging cycles before they die. One of the reasons lithium-ion batteries degrade is their use of nanowires to carry electricity. Nanowires are extremely thin. A human hair is thousands of times thicker, for example. Nanowires are extremely efficient carriers of electricity, which makes them useful in batteries.
“The ingredients are blended and heated until the mixture is thick enough. At this point, I add the spices and flavorings before pouring it into a mold to set for 24 hours, ”Grounds said. These noodle parcels are then packaged in a wax-coated paper.
Now, instead of plastic packs of seasonings(调料), the dried spices and flavorings are part of a flavorless bioplastic film that wraps the noodles and keeps them fresh. The film dissolves in less than a minute when it comes into contact with boiling water, according to Grounds, and the liquid becomes the sauce for the noodles and larger ingredients like dried shrimp.
With plastics taking hundreds of years to decompose and filling landfills and oceans globally, eatable packaging and single-use items are seen as the way to go. Grounds sees opportunities to use her eatable packaging for other ready meals and she wants to contribute to the global fight against single-use plastics. 【文章大意】本文是一篇说明文。食品包装袋给食物套上精致的外衣, 却让环 境为之买单。近日, 英国一大学生制作出一种可食用包装袋, 这种食品袋集包 装、防腐、调味为一体, 热水冲泡后几分钟内化为汤料, 方便又环保。
A Ramen noodles have been a go-to(首选的)food for students for decades. After all, they only take eight minutes to cook in a dorm hotpot and are easy on the budget . Holly Grounds, a recent project design graduate of Ravensbourne University, in London, used to eat a lot of ramen noodles when she studied. But it got her thinking that the packaging of a product that takes just minutes to cook and eat shouldn’t take decades or more to decompose(分解). That’s why she decided to make eatable wrappers for noodles, avoiding the need for plastic.

B When a laptop or smartphone battery starts losing its power, the only options are to buy an expensive replacement, or just keep it plugged in all the time.
