The way is opened to accelerate charging of accumulators in 3 times



Every year, the power of mobile devices grow, but the batteries behind them do not keep pace. Therefore it is already considered the norm to have a plug for the outlet and a couple of power banks in addition. And if you can not fundamentally change the device battery, you can try to make them at least less dependent on the outlet. This is exactly what the scientists from Germany did, creating a technology that significantly accelerates the charging of batteries.



About the new development, the edition of Advanced Functional Materials is being published. As stated in the article, a group of German scientists developed a process for the synthesis of a hybrid material consisting of nanoparticles of tin oxide doped with antimony. All particles do not exceed a size of 3 millimeters and are grown on a platform of graphene, which provides structural stability and increases the electrical conductivity. As the author of the study, Dean Fattahowa-Rolfing of the Research Institute of Energy and Climate in Jülich, states,

"Antimony doping improves the ability of a material to absorb lithium ions and makes the anode faster. Thus, it is capable of storing one and a half times more energy per minute than is possible with conventional graphene anodes. As a result, for 1 hour of charging, the amount of energy stored is increased 3 times. "

High energy density is retained even after 1000 recharging cycles, keeping more than 77% of the original capacity, which is an extremely good result.

"Composite materials of nitric oxide on the carbon matrix allow us to overcome the limitations of individual material, such as low cyclic stability caused by large changes in volume during charge-discharge.

The Zowi robot from BQ is already 'made in Spain' Spanish technology begins to produce its educational toy in its factory in Navarra, where it also assembles 3D printers    The Spanish technology company BQ has begun to manufacture its educational robot Zowi in the factory that the company has in Noáin (Navarra), where for three years it has been manufacturing 3D printers and 'Do it yourself' (DIY) products. "The objective of BQ has always been to manufacture in Spain all products for which you can count on a local supplier ecosystem," they say from the company.   Zowi, the robot that discovers children how technology works, is a toy that facilitates a real first approach between the child and technology. You can play with it and control it from your app, disassemble it and reassemble it easily to access its circuits or create your own programming projects. In addition, it evolves with the child: every time he completes a project, he unlocks new functi...

Bose develops headphones with white noise specifically for sleep

Bose develops headphones with white noise specifically for sleep If you live in one of the new buildings, you like no one else know what thin walls and the absence of any kind of sound insulation. Bad acoustics, knocking, screaming, noise, roosters, trains, the continuation of the family - all this gets into a dream and destroys it. If I could give up sleep, I would have long abandoned this ungrateful pastime. In the US, the problem of lack of sleep costs the economy 411 billion dollars a year. Lack of sleep makes you "boiled" and unable to work normally. So Bose wants to solve this problem. The company presents SleepBuds, headphones that will help people sleep. Wireless headphones are the result of the recent acquisition of Bose, the startup Hush, which develops "smart inserts." New headphones will sit comfortably in your ears even if a person sleeps on his side. According to those who have already met with them, Sleepbuds are surprisingly convenient, they are diff...

Benefits and Challenges of Data Center Consolidation

Benefits and Challenges of Data Center Consolidation Given the ever-growing business demands for IT offerings, physical space is at a top class in many facts center centers. on the other hand, some of businesses are looking to consolidate their data centers with a view to keep cash, streamline operations and enhance energy efficiency. There are a number of drivers for consolidation projects. In a few instances, the enterprise grew thru mergers and acquisitions, inheriting more than one statistics centers that replicate offerings. in addition, many agencies have correctly reduced their IT footprint via virtualization and the adoption of hyper-converged infrastructure answers. these technologies make it feasible to dispose of underutilized system and update what stays with smaller shape elements. The clarification of those services also can facilitate consolidation. This has been a priority in the federal government through the Federal records middle Consolidation Initiative. Federal ...
