Chemists have constructed coque iphone 5c drapeau français a bow tie shaped molecule that changes colour under different conditions. coque huawei coque samsung coque iphone 5c chantier It could be used to monitor toxic chemicals in air.

Huan Cong at the comparatif coque iphone 8 Technical Institute of Physics and Chemistry in China and his colleagues assembled the substance, which they call coque iphone 6 fleuri BowtieArene, coque samsung by connecting two pentagon shaped molecules called pillararenes. The two pillararenes were bouygues coque iphone 6 joined by a fluorescent molecule called tetraphenylethylene that formed the “knot” of the bow tie.

contrast, when the researchers coque iphone 5c gucci pas cher broke coque iphone 6 noir transparent these ordered structures apart, coque iphone coque samsung either by mechanically grinding or scratching the crystals or dissolving them in liquid, bijoux bracelets the separated bow ties emitted green or yellow fluorescence.

Next, coque iphone Tshirt pokemon coque samsung the team coque iphone ghost showed they could coque iphone avec fleur make the bow ties blue again by exposing them coque coque iphone 6 rosace iphone 6 kaneki to the vapour of a chemical called xylene, coque samsung which pulled the coque iphone 4 coque iphone 6 hermione silicone panda individual molecules obey coque iphone 5s back into an orderly arrangement.

This colour switching property could be used to make sensors that detect coque iphone 6 napoleon toxic chemicals in the air or reveal when mechanical forces are present, coque huawei says Cong. coque huawei His team is currently designing different versions of the bow coque iphone 6 kpop tie molecule to detect a range of different chemicals.

This isn’t coque iphone 7 skateboard the first time that chemists have made coque iphone 6s nike supreme molecules coque iphone 7 de qualité with wacky coque iphone 6 polo ralph lauren shapes. coque huawei They have also assembled molecules coque iphone géométrique in the shape of churches, coque huawei houses, kawaii licorne Japanese pagodas, baskets, coque iphone coque iphone bird coque iphone coque iphone 6 hype 5c gateau cages,
