Consider you have taken the backup of Drive:\Documents and Settings\All Users folder when the Background Intelligent Transfer Service (BITS) runs, after that if you will try to open the report for the backup activity, you can notice the following error message

New Micro battery, power packed for high performance

For a size of a few millimetres, the new micro-batteries are powerful enough to jump start a car battery and then quickly charge the cell phone. Researchers from the University of Illinois have developed the micro batteries which can be used to drive compact electronic devices and new applications for radio communications. The micro batteries are so good that they can even out power the super capacitors. The results were published in ‘Nature Communications’ in the April 16 issue. The micro batteries have energy and power and with the researchers tweaking the structure of the micro batteries a little bit, its use can be for wide range applications. The high performance of the micro battery is based on its 3-dimensional micro-structure. Based on the design of fast charging cathode by Professor Paul Braun’s group, researchers developed the matching anode and integrated it with the fast charging cathode at a micro-scale and made a complete battery with high performance. These batteries cou
