Limitless Clean Water Everywhere: Carbon Nanotubes Could Make it Happen, Or Can They?

There were high hopes of using carbon nanotubes, particularly for ultra-fast water transport to desalinate seawater. However, a simulation now reveals that these ultra-fast transport rates might have not been properly grounded after all. Researchers who work with experiments and computer models have...

Building 3D Fractals on a Nano Scale

A fractal is a geometric structure that can repeat itself towards infinity. Zooming in on a fragment of it, the original structure becomes visible again. A major advantage of a 3D fractal is that the effective surface rises with every next step.
