（2022潍坊高三期中卷）Electronics woven (编织) into fabrics promi to open up all kinds of interesting possibilities, from clothing that monitors muscle activity and tracks breathing, to garments that can talk to one another. Developing pliable power sources to go with them is an equally important field of rearch, so scientists at the University of British Columbia have put forward a particularly impressive solution that they say could be the first ever battery that is both stretchable and washable.
To develop a battery with such capabilities, the scientists reimagined the way the devices are put together. Rather than forming a lithium-ion battery packed with hardened materials inside a rigid exterior, the team turned to an alternative chemistry in zinc-mangane (锌锰) dioxide, which is appealing for its low cost and safety. The materials were ground down into tiny pieces and int in a polymer (聚合物) to form very thin and stretchable layers.
“We went with zinc-mangane becau for devices worn next to the skin, it’s a safer chemistry than lithium-ion batteries, which can produce deadly compounds when they brea
k,” says Nguyen.
The resulting battery is flexible and can be stretched to twice its normal length, has a specific capacity of 160 mAh g-1 and keeps 75 percent of its capacity over 500 charge and discharge cycles. Impressively, the team found the battery to withstand 39 wash cycles so far.
The team is now working to improve the power output and lifetime of the battery, and says the creation has already attracted commercial interest, with the cost expected to be similar to a standard rechargeable battery. They imagine it being put to u in watches and patches that measure vital signs, and in smart clothing that does much the same thing.

e been the first poultry species to have been domesticated (驯养) by humans—as far back as 7,000 years ago.
Scientists have long held different opinions on the history of the domestication of birds, with a belief that it was chickens that were the first to be domesticated. In 2014, Chine 三个火枪手2
rearchers reported ancient DNA taken from the earliest archaeological chicken bone discovery in China, suggesting chickens were domesticated in northern China as early as 10,000 years ago.
But the rearchers behind the latest findings say that the 2014 study lacks firm evidence. In the new study, the team unearthed the archaeological site of Tianluoshan, a 7,000-year-old rice cultivation village in the lower Yangtze River valley in what is today known as East China’s Zhejiang province. They found a total of 232 goo bones at the site. The inhabitants of the village were hunter-gatherers.
The rearchers ud multiple approaches to study the bones, and found evidence of domestication.
Four bones were from goslings (幼鹅) ranging from eight to 16 weeks old, suggesting they hatched near the site. Gee were domesticated from wild gee. The migratory birds fly to northern Siberia to breed (繁殖) after the spring and then fly south for the winter, according to rearchers from the Zhejiang Provincial Institute of Cul
tural Relics and Archaeology. They said the goslings were too young to have flown in from elwhere. At the time, Tianluoshan did not have the conditions to be a natural breeding place for wild gee, so it follows that the goslings were born after domestication.
