Photosynthesis Helper Protein Discovered

Photosynthesis is less efficient in plants than it could be. Red algae, in contrast, use a slightly different mechanism and are thus more productive. Scientists from Germany's Max Planck Institute of Biochemistry (MPIB) have now identified a helper protein for photosynthesis in red algae.

Affordable Solar Option for Power Plants

Solar thermal power plants - which use high temperatures and pressure generated by sunlight to produce turbine movement - are an environmentally-friendly alternative to standard power plants. But this can be expensive, especially when it comes to equipment made from expensive metals and the solar high-accuracy concentrator technology used to harvest solar energy.

Composite Metamaterial for Solar Tech

A Northwestern University research team has developed a new material that absorbs a wide range of wavelengths and could lead to more efficient and less expensive solar technology. The researchers used two unconventional materials – metal and silicon oxide – to create thin but complex, trapezoid-shaped metal gratings on the nanoscale that can trap a wider range of visible light.

Transparent Conducting Oxides and Undercoat Technologies for Economical OLED Lighting

Economics is a key factor for application of organic light emitting diodes (OLED) in general lighting relative to OLED flat panel displays that can handle high-cost materials such as indium tin oxide (ITO) or indium zinc oxide (IZO) as the transparent conducting oxide (TCO) on display glass. For OLED lighting to penetrate into general illumination, economics and sustainable materials are critical.
