Purifying water with the help of wood, bacteria and the sun

According to the United Nations, about one-fifth of the world's population lives in areas where water is scarce. Therefore, technologies to produce clean water from undrinkable sources, such as seawater, river or lake water, ...

Transporting energy through a single molecular nanowire

Photosynthetic systems in nature transport energy very efficiently toward a reaction center, where it is converted into a useful form for the plant. Scientists have been using this as inspiration to learn how to transport ...

Energy flow in the nano range

Plants and bacteria can capture the energy of sunlight with light-harvesting antennas and transfer it to a reaction center. Transporting energy efficiently and in a targeted fashion in a minimum of space is also of interest ...
