Butterfly to improve solar energy efficiency

Cabbage White butterflyScientists at Exeter University have been taking a long hard look at the Cabbage White butterfly and believe the way it flies will help to make solar energy cheaper and improve its efficiency.

Cabbage White butterflies take a v-shape posture to warm their muscles before they take off, and the Exeter researchers believe that by mimicking this posture, solar panel could deliver nearly 50 percent more power.… Read the rest

Superfast device promises ultrafast computing

Silver gold interaction - Duke UniversityScientists at Duke University said they have created an ultrafast light emitting device that can switch on and off at 80 billion times a second.

And this, they said, could well form the basis of very fast optical computing.

Scientists have known for a while of the concept using lasers but they need too much energy and they’re not suitable for integrating into chips.… Read the rest

Sticky tape opens up solar cell markets

The discovery of phosphorous - - detail from painting by W. Pether of Brandt, an alchemist, discovery of phosphorousA team of researchers at the Australian National University (ANU) has hit on a way that it could mean ultrathin and ultralight solar cells and LEDs will be available.

The discovery is based on the element phosphorous which the researchers showed could produce single atom layers called phosphorene using simply sticky tape.… Read the rest

Transistors get atomic

atomium-BelgiumBoffins have emerged from their smoke filled labs with a transistor which works at an atomic level.

Physicists at the punchy titled Paul-Drude-Institut für Festkörperelektronik (PDI) institute and the Freie Universität Berlin (FUB), along with chums at the NTT Basic Research Laboratories (NTT-BRL), Japan, and the US Naval Research Laboratory (NRL) used a scanning tunnelling microscope to create a minute transistor consisting of a single molecule and a small number of atoms.… Read the rest
