 Quite futuristic architectural design, which gives the start of a new direction in the development of smart jewelry with the use of flexible touch screens. In the near future technology flexible touch screens will be a part of our daily life as a public subject goods not only in devices but also in other fields of application.
 Carnival smart mask, which is made of a flexible touch surfaces in their ability to change colors and to reproduce the desired information on its front part. Direct pairing with Your gadget, with the help of the eponymous mobile app that will allow you to change the information displayed on the touch surface of the smart mask in accordance with situational requirement. Charging can be made as a standard way and using the new wireless charging technology. The holder of the charge will serve as a flexible battery.
 Quite convenient to use this device carrying out all sorts of creative events, which simplifies the task of changing costumes and masks. Or just various holiday events and parties, which will be a new kind of fun and games with shifts appearance smart carnival masks. As a separate function, the masks will be mounted video cameras , which will increase their scope. The show, which will use data from smart devices will be much colorful with the rapid increase of promotion.
 This author's idea is open for investment and complete its foreclosure.

Scientists around the world are looking for an alternative to lithium-ion batteries. Magnesium batteries in theory have a larger capacity, but so far chemists have not been able to find the right material to make a cathode. The solution was found by a group of researchers from the University of Chicago.
The main limiting factor of modern lithium-ion batteries is the anode. For safety reasons, it is made of carbon materials, since in this case the risk of short circuits and fire is minimized. However, as a result, the capacity of the battery decreases, and with it the life of the device.
Using lithium metal anodes is dangerous. But the anode based on metallic magnesium reduces the risks to a minimum. If you use it with a functional cathode, you can create a more powerful battery of a smaller size.
"Magnesium batteries will extend the life of smartphones and increase the range of electric vehicles," - says study author Ian Johnson.
But, as the chemist explains, the problem of selecting a suitable material for the cathode remained unsolved for a long time.

The mathematical model has shown that a material based on magnesium oxide and chromium, MgCr2O4, can become a promising "candidate" for the cathode. In the course of the experiments, American scientists obtained a material with a disordered structure 5 nm thick with a high reaction rate at a relatively low temperature.
Then it was compared with the usual material with an ordered structure with a thickness of 7 nm. A series of tests, including X-ray diffraction analysis and X-ray absorption spectroscopy, revealed significant differences. It turned out that disordered particles have a more advantageous set of properties.
"The study proves that at the heart of the new type of battery may lie disordered, non-standard structures," - quotes Professor Javward Darr ScienceDaily.
Scientists suggest that other materials with structural defects that researchers have previously ignored may prove to be effective. American chemists are hoping that further research will enable them to create functional magnesium batteries. The results of their experiments, they published in the journal Nanoscale.
Around the world, batteries are being developed, which in the future will replace lithium-ion batteries. So, in China they are already setting up production of solid-state batteries, MIT is experimenting with aluminum-air storages, other American scientists are betting on fluorides and nickel-hydrogen systems.
