The solar cell that builds itself

Researchers have demonstrated a simple, cheap way to create self-assembling electronic devices using a property crucial to salad dressings. It uses the fact that oil- and water-based liquids do not mix, forming devices from components that align along the boundary between the two.

The idea joins a raft of approaches toward self-assembly, but lends itself particularly well to small components. The work is reported in Proceedings of the National Academy of Sciences. Crucially, it could allow the large-scale assembly of high-quality electronic components on materials of just about any type, in contrast to "inkjet printed" electronics or some previous self-assembly techniques.

Science of suffering Environment

It is actually distressing to know that except man all the other animals have learned to live with the environment. No animal in the history of the world have caused such damages to the nature. Man has long been in search of luxury ever since his evolution. Science is the tool which man has to achieve what he desires, but at what cost. He has made the environment deteriorate in an alarming extent. Quick steps need to be taken by man to turn the clock in favour of the Mother Nature. If there is any delay then man will succeed in digging his own grave. Quick action is the need of our to restore Mother Nature.
