Stay super-dry with new nanotechnology

March 09, 2012

What happens when a drop of water falls on a lotus leaf? It’s not a philosophical question, but a natural phenomenon scientists have been studying, and trying to make sense of, for hundreds of years.

The drop of water falls, bounces, and rolls away without trace – leaving the leaf clean and water repellant.

Now scientists at the Nokia Research Center in Cambridge believe they may be able to replicate the same effect on your phone, using nanotechnology.

Chris Bower, the Principal Scientist at the NRC in Cambridge, sums it up:
“Like many scientists we are trying to copy what nature has been doing perfectly for thousands of years.”

To achieve the water-resistant, and stain-resistant, qualities of a lotus leaf the team at NRC is in the final stages of designing a Superhydrophobic coating which would be applied to the outside of a mobile phone.

If you’ve ever used a Teflon non-stic… [more]

Nokia 808 PureView: How to make the perfect Carl Zeiss lens

March 09, 2012

The size of the Carl Zeiss lens for the new Nokia 808 PureView is smaller than a sugar cube, and the lens for a Nokia Lumia 800 is only slightly bigger than a pin – but both produce images as sharp as a ZEISS lens used on a professional photographic camera.

Dr Hubert Nasse is the Senior Scientist at Carl Zeiss Camera Lens Division, and tests lenses rigorously in the ZEISS labs. He loves lenses.

“I spend my working life testing lenses to the very highest scientific standards,” he says. “And of course that is how you accurately judge that a lens meets ZEISS specifications. But there is more to a lens than that – when you work with lenses every day, you appreciate their true craftsmanship. A ZEISS lens even has a certain smell – to me it smells professional.”

Nasse fits the lens from a Nokia Lumia in the Carl Zeiss K8 measuring machine – which takes up most of the … [more]
