本质安全What if clothing was more than just an accessory? The green movement is not new to fashion, and many designers and manufacturers have been actively eking out ways to ensure their garments have less of an environmental impact. But what if your clothes were actually able to have a 1 impact on the environment?
This vision is one shared by the two founders of Catalytic Clothing(触媒服装): Professor Tony Ryan, a scientist from the University of Sheffield, and Professor Helen Storey, a designer and artist from the London College of Fashion. Together they are working on a project that draws on the growing field of nanotechnology(纳米技术) to create a fabric 2 that can break down pollutants in the air.
霸王花2>火灾自救逃生方法"In a n, it"s a recycling of an existing technology that exists in toothpaste and sunscreen," Professor Storey explains. The additive contains nanoparticles of titanium dioxide which act as a catalyst (触媒剂；催化剂). When light hits the particles, they react with oxygen to make what is esntially a peroxide(过氧化物) bleach. This in turn reacts with air 3 such as nitric oxide and breaks them down.
While this technology could be ud to create an entirely new fabric, Professor Ryan thinks that it has greater potential as an additive. "It only needs to be on the surface," he says. "You don"t 4 it in the fibers, and that means that it"s really easy to upgrade existing fabrics with the technology. We think the best way to do this is via the laundry, becau everyone washes their clothes."
Jeans have been a particular focus of Catalytic Clothing, both becau they are widely prevalent as well as that the particles 5 especially well to cotton denim. And while the amount of air pollutants broken down by any one individual wearing catalyzed jeans is minor, " 6 , we can have a huge impact on the quality of the air and therefore respiratory health," Storey says.
According to Ryan, 4 people wearing catalyzed jeans in a day would 7 the nitric oxide air pollution created by one car.
The future might be one in which this pollution-busting fabric additive is so 8 that we no longer give it a cond thought, like fluoride(氟化物) in tap water. Though at the moment it"s **mercially 9 , Ryan estimates that it could be with in a year or class. Catalytic Clothing is aiming for mass 10 . The day is near when we"ll be able to make our clothes work for us in more ways than one.

Phew, what a relief. It ems that the Royal Shakespeare Company and Shakespeare"s Globe won"t have to change their names any time soon. The squabble so beloved by academics, conspiracy (阴谋) theorists and Hollywood film-makers—which only surfaced in the mid-19th century but continues to 11 on—over the authorship of Shakespeare"s plays, may finally be called to a halt by a new book.
In Shakespeare Beyond Doubt, leading scholars organize the arguments and evidence to prove that Shakespeare really did write Shakespeare"s plays. It puts paid to 12 that Shakespeare was the Earl of Oxford (as suggested by the movie Anonymous), or Christopher Marlowe or Francis Bacon, or even Queen Elizabeth Ⅰ when she was having a day off from running the country. Great. That means the rest of us can just go on eing and enjoying the astonishing plays, which may have 13 authorship, but which are constantly revealing in their examination of what it means to be human.
Except that it won"t. The arguments, between tho who want to rewrite 14 history and t
ho who don"t, will keep going, constantly fueled by any kind of conspiracy theory—the madder the better—and the fact that there is now so much money, and so many academic careers, 15 up in the Shakespeare industry.
