Hidden talents: Converting heat into electricity with pencil and paper

21/02/2018

Thermoelectric materials can use thermal differences to generate electricity. Now there is an inexpensive and environmentally friendly way of producing them with the simplest of components: a normal pencil, photocopy paper, and conductive paint are sufficient to convert a temperature difference into electricity via the thermoelectric effect.

Breaking local symmetry: Why water freezes but silica forms a glass

20/02/2018

University of Tokyo researchers simulated water and silica at low temperature. Despite structural similarities, the two liquids act differently when they are cooled: water freezes into ice, while silica continues to supercool, and eventually forms a glass. This arises from poor symmetry-breaking in silica; although atoms arrange properly in the first shell in both liquids, local rotational ...

Your gadget's next power supply? Your body

16/02/2018

Searching for a power outlet may soon become a thing of the past. Instead, devices will receive electricity from a small metallic tab that, when attached to the body, is capable of generating electricity from bending a finger and other simple movements.

New approach could quickly identify best organic solar cell mixtures

15/02/2018

An international team of researchers has discovered a new quantitative relation that allows for quick identification of promising material combinations for organic solar cells. The discovery could significantly reduce the 'trial and error' aspect of solar cell production by reducing the time spent on finding the most efficient mixtures.

Smart new method to manufacture organic solar cells

15/02/2018

The ability to use cheap materials and simple manufacturing methods are two huge advantages of printed organic solar cells. Olle Inganäs, professor at Linköping University, is head of a research group that has now developed an even simpler method to manufacture solar cell modules. The results have been published in the scientific journal npj Flexible Electronics.
