Intense laser light modifies the pairing of electrons

The quantum-mechanical exchange interaction between electrons can be specifically modified with intense infrared light fields on time scales of a few femtoseconds, as time-resolved experiments on sulfur hexafluoride molecules show. This finding lights a way for bottom-up controlling chemical reactions with lasers in the future - based purely on electrons, the 'glue' of chemistry.

Converting solar energy to electricity on demand (w/video)

The researchers behind an energy system that makes it possible to capture solar energy, store it for up to eighteen years and release it when and where it is needed have now taken the system a step further. After previously demonstrating how the energy can be extracted as heat, they have now succeeded in getting the system to produce electricity, by connecting it to a thermoelectric generator.

Maintaining the nanostructure of gold and silver in alloys

Engineers have developed a low-temperature annealing method that maintains the structure of gold and silver when the two metals are combined in an alloy. Their discovery will prove useful in the manufacture of contact lenses, holographic optical elements and other optical components, since the new alloys reflect the full spectral range.
