How to make a "perfect" solar absorber
The key to creating a material that would be ideal for converting solar energy to heat is tuning the material's spectrum of absorption just right: It should absorb virtually all wavelengths of light that ...
Team reveals molecular structure of water at gold electrodes
When a solid material is immersed in a liquid, the liquid immediately next to its surface differs from that of the bulk liquid at the molecular level. This interfacial layer is critical to our understanding ...
Calcium absorption not the cause of evolution of milk digestion in Europeans
Ancient DNA from early Iberian farmers shows that the wideheld evolutionary hypothesis of calcium absorption was not the only reason Europeans evolved milk tolerance.
Scientists synthesize molecules that absorb any color of sunlight, from the oranges through the near-infrared
In 2005, scientists studying tiny sac-like creatures called sea squirts found bacteria containing two types of chlorophyll (a and b) in cavities inside the squirts' tissues. These two pigments were soaking ...
Tandem polymer solar cells that set record for energy-conversion
(PhysOrg.com) -- In the effort to convert sunlight into electricity, photovoltaic solar cells that use conductive organic polymers for light absorption and conversion have shown great potential. Organic polymers ...
