London, Jan 8 : A team of scientists has observed a quantum effect that causes objects to repel one another, which could be used to lubricate future nanomachines.

According to a report in New Scientist, the team detected the weak repulsive force when they brought together a thin sheet of silica and a small gold-plated bead, about half the diameter of a human hair.

The force is an example of the Casimir effect, generated by all-pervasive quantum fluctuations.

London, Jan 8: Chemical engineers in the US have created the world''s smallest working fuel cell, which may lead to the development of environmentally-friendly portable gadgets in future.

At just 3 millimetres across, future versions of the tiny hydrogen-fuelled power pack will be able to store more energy than batteries and that too in the same space.

Still, it's easier to make batteries at the small scale than the pumps and control electronics of a fuel cell.

In fact, small pumps tend to utilise more energy than they generate.
