Quantum dots form ordered material

Quantum dots are clusters of some 1,000 atoms which act as one large "super-atom." It is possible to accurately design the electronic properties of these dots just by changing their size. However, to create functional devices, ...

It is not enough to save water. We must also reuse it

Clean water is becoming a scarce resource, and one in four people in the world have no access to a safe source of drinking water. Population growth and climate change are making water shortages even worse. For this reason, ...

Energy storage materials built from nano-sized molecular blocks

Molecules of the rare metallic element niobium can be used as molecular building blocks to design electrochemical energy storage materials. Mark Rambaran, Department of Chemistry at UmeƄ University, presents in his thesis ...

Cilia in 3D: Miniature 'train station' discovered

Cilia are small hair-like organelles that extend from cells and perform many functions, including motility and signaling. Researchers have now revealed that cilia have a specialized transport hub at their base, where trains ...
