Russian Federation It Absolutely not true. In the online stores sell the same products as in conventional stores, they are subject to the same warranty and they also fall under the Law of the Russian Federation. Price is lower due to savings on rental of retail space. To fully functioning online store requires a website, warehouse and several employees. And the selection of online stores is much greater than in conventional stores. Upon receipt of your order, you get a warranty card and can in case of problems, contact the nearest service center of any manufacturer. Site not fully include the online store. It is rather a showcase site, since the functional site can only view the products and descriptions. Order is not done on the site and by phone. Here is an amateur. Perhaps, after all we will soon see a completely redesigned and multi-engine. Of advantages worth noting a lot of background information. Many interesting can be found, for example, about the city of Penza, historical facts, etc. Here the creators have tried to connect online store and information portal. In any case, "Penza-trade" deserves a solid "four". Second we considered an online store much more interesting, as to the functional and design. This store digital electronics "Technology Penza (www.TehnikPenzy.ru). He was later opened in 2008. In 2010 management decided to completely redo the store management system. In my opinion, is more interesting and more convenient. Now this is really a full-featured online store, which You can see the specifications and product descriptions, photos, read customer reviews.

Nanotechnology That is, although the computers themselves are moving rapidly, the supply of batteries - in laptops, mobile phones and other devices, snabzhnnyh microprocessors - are lagging behind due to chemical constraints. However, thanks to a breakthrough from Stanford researcher Yi kyi, lithium-ion batteries that feed most of these devices can store up to 10 times more electricity. Solution was found, which helped to nanotechnology. Litivo-ion batteries work by transferring lithium ions from the anode, usually made from coal, to metalooksidnomu cathode. Ugolny anode can hold no more than one ion to six carbon atoms. The silicon plate for By comparison, holds a much greater charge lithium ion 4.4 to one silicon atom. However, when charged silicon increases the possibility of four, leading to its cleavage as the anode and thus making it unfit for use in batteries. The discovery lies in the fact that silicon nanostructures width of 100 nanometers, do not break during expansion. This phenomenon remains a mystery. Perhaps their small size prevents gap may be something else, or they svoistva fundamentally different. However, the results obtained by Yi kui, amazing. According to the latest published data, Yi kui uvelisil number of charge-discharge cycles from 30 to 1000, in result, capacity has reached over 4,200 indicators miliamper hour, which is 10 times higher than conventional lithium-ion battery. Imagine a laptop that can operate without recharging for two days, or electric, the traveler on a single charge from Moscow to the Crimea. Increased battery capacity impact on everything, increasing the service life - and umenishaya size - cell phones, laptops, and possibly even leading to the appearance of practical electric vehicles. Furthermore, while modern lithium-ion batteries for the most part stable and secure, numerous press reports about the bombings indicate a need for notebooks careful attention to the aspect...
