16-02-03 chinese researchers have created a plastic polymer with shape memory, allowing it to switch between designs when exposed to heat. 中国科研人员创造一种具有形状记忆能力的塑料聚合物,该材料在受热的时候可以变换形状。 zhejiang university scientists say i...
16-01-31 imagine a polymer with removable parts that can deliver something to the environment and then be chemically regenerated to function again. or a polymer that can lift weights, contracting and expanding the way muscles do. these functions require poly...
15-07-29 nearly four billion years ago, the earliest precursors of life on earth emerged. first small, simple molecules, or monomers, banded together to form larger, more complex molecules, or polymers. then those polymers developed a mechanism that allowed...
14-06-10 university of akron polymer scientists have developed a transparent electrode that could change the face of smartphones, literally, by making their displays shatterproof. in a recently published scientific paper, researchers demonstrated how a trans...
13-11-19 researchers have made the first battery electrode that heals itself, opening a new and potentially commercially viable path for making the next generation of lithium ion batteries for electric cars, cell phones and other devices. the secret is a str...
13-08-11 for most of us, a modern lifestyle without polymers is unthinkableif only we knew what they were. the ordinary hardware-store terms we use for them include plastics, polyethylene(聚乙烯) , epoxy resins(环氧树脂) , paints, adhesives, rubber -- wi...
13-01-18 gas separation is crucial for many industrial processes including obtaining nitrogen or oxygen from air and purifying natural gas or hydrogen. currently, the most energy efficient method for separating gases involves polymer membranes, however, most...
11-07-15 in 1997, the actress and singer julie andrews lost her singing voice following surgery to remove noncancerous lesions(损害) from her vocal cords. she came to steven zeitels, a professor of laryngeal(喉的) surgery at harvard medical school, for h...
10-09-29 conductive polymers(聚合物,高分子) are plastic materials with high electrical conductivity that promise to revolutionize a wide range of products including tv displays, solar cells, and biomedical sensors. a team of mcgill university researchers...
