Cheap electricity with Artificial Leaf which can self heal













An artificial leaf was created by scientists, way back in 2011 and this leaf could mimic the real leaf in producing energy from water and sunlight. It was promoted as a possible inexpensive source to generate electricity, at least for the developing countries and for remote locations. The artificial leaf is a simple silicon wafer covered in a catalyst. This wafer is then dropped in a can of water and kept in sunlight. The artificial leaf then breaks down the water into oxygen and hydrogen gases. The gases, which come up as bubbles are collected and can be used to power electricity in fuel cells.


It was found that the artificial leaf is prone to bacteria build up on it and the process of generating energy is halted because of the bacteria cover up. Scientists have now further refined the process for the artificial leaf with new catalysts developed which will allow the lead to heal itself which means that the leaf can even work in dirty and muddy waters. It is being assumed that about 0,25 gallons of water would be able to produce about 100 watts in a 24 hour cycle.

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…

Google Health Login Page is Ready!

Google's Marissa Mayer announced that the Google Health will be launched on 2008. The service of the
Google Health Login Page is ready. It's only the first intro page is displayed and I didn't get passed to the next page. In the same page y0u can see the information displaying on the Google Health. If you point your mouse on the below link you can visit the Google Health Page
https://www.google.com/accounts/ServiceLogin?service=health

With Google Health, you can:
* Build online health profiles that belong to you
* Download medical records from doctors and pharmacies
* Get personalized health guidance and relevant news
* Find qualified doctors and connect to time-saving services
* Share selected information with family or caregivers

This will be a nice development about caring health and this will helps in having some cautious about health.
