Fabrics to 'pass' cold



Engineers from Stanford University develop a fabric that refreshes the body in warm places



   The first full week of September brings a new mercury rise of thermometers, extreme heat that leads researchers to find solutions to lower the temperature.

Researchers at Stanford University have developed a low-priced, plastic-based textile that interwoven in the fabric refreshes the body much more efficiently than the natural or synthetic fabrics of the clothes we wear today.

"If you can refresh people, it's better than refreshing the building in which they live or work, so we'll save energy," Yi Cui, an associate professor at the University, said in a statement.

    Research from Stanford University allows the heat emitted by the body to be transferred by the textile. "Until now there has been very little or no research on tissue design according to its thermal radiation characteristics," says Fan, one of the project's researchers.

For the development of the new plastic fabric, the researchers used nanotechnology, photons and chemistry to confer polyethylene a series of desirable characteristics for a material that is used to dress.

The Stanford experts did have to face two problems in the use of polystyrene: that it is waterproof and that it lets in light.

To solve these problems, the researchers found a polystyrene variant that has a nanostructure that is opaque to visible light, but transparent to infrared radiation, which allows the body's heat to escape.

And her decision to complain to the prosecutor 's accounts of 2017 can bring tail.   That announcement was made on Friday, after presenting the worst results in its history with losses of 352.6 million euros last year, and was the result of an investigation ( report 'forensic' ) commissione...

Mercadona and Lidl grow thanks to the decline of Dia engaged in its worst crisis The supermarket chain drops by 0.7% in 2018 to 7.5% market share, despite "not yet accounted for the negative effects of layoffs", explains the head of retail sector of Kantar Worldpanel Mercadona and Lidl grow thanks to the decline of Dia in the year of its worst crisis. The supermarket chain drops by 0.7% in 2018 to 7.5% market share, despite "not yet accounted for the negative effects of layoffs", explains the head of retail sector of Kantar Worldpanel . The Valencian chain Mercadona remains one more year the undisputed leader for Spanish consumers with a market share of 25%. This means that 1 of every 4 euros spent on mass consumption goes to the firm of Juan Roig, which has strengthened its position especially in fresh products, which account for half of what we Spaniards spend in the shopping cart, according to the figures of the report 'Balance of the Distribution...
