New Evidence for Liquid Water Beneath the South Polar Ice Cap of Mars

An international team of researchers has revealed new evidence for the possible existence of liquid water beneath the south polar ice cap of Mars. The researchers used spacecraft laser-altimeter measurements of the shape of the upper surface of the ice cap to identify subtle patterns in its height. They then showed that these patterns match computer model predictions for how a body of water beneath the ice cap would affect the surface.

Insight into the long-term stability of solar cells

A researcher has developed an experimental set-up in which the degradation of solar cells can be accelerated and the degradation monitored in real time. The experimental set-up has been well received in the photovoltaic world and is now being commercialised.

Armor unveiling new activity: current collector films for batteries

Armor markets two types of products: the thin Thermal Transfer film meant for printing on packaging and labels, as well as remanufactured ink jet and laser cartridges.

Layer of gold nanodots could improve organic solar cell efficiency

A layer of gold nanodots on the surface of indium-tin oxide (ITO) coated glass may improve the efficiency of organic photovoltaic cells, according to new research published in the journal, Gold Bulletin.

Layer of gold nanodots could improve organic solar cell efficiency

A layer of gold nanodots on the surface of indium-tin oxide (ITO) coated glass may improve the efficiency of organic photovoltaic cells, according to new research published in the journal, Gold Bulletin. The paper, written by an international team from France and Denmark, explains how a discontinuous film of gold nanodots just 0.5nm thick is sufficient to generate the performance improvement.
