Minuscule pillars double the efficiency of solar cells

Solar cells are generally flat. However, by adding minuscule silicon pillars to the surface, it is possible to more than double the amount of energy produced for each surface. This has been demonstrated by research by academics ...

New material structures bend like microscopic hair

MIT engineers have fabricated a new elastic material coated with microscopic, hairlike structures that tilt in response to a magnetic field. Depending on the field's orientation, the microhairs can tilt to form a path through ...

Nanostructures filter light to order

Arrays of nanoscale pillars made to reflect light of a selected color could find application as optical filters in digital cameras.
