Capturing living cells in micro pyramids

A field full of pyramids, but on a micro scale. Each of the pyramids hides a living cell. Thanks to 3D micro- and nano scale fabrication, promising new applications can be found. One of them is applying the micro pyramids ...

In static friction, chemistry is key to stronger bonds

(Phys.org)—Inspired by phenomena common to both earthquakes and atomic force microscopy, University of Wisconsin–Madison materials engineers have learned that chemical reactions between two silicon dioxide surfaces cause ...

Solar cells made from black silicon

Solar cells convert three-quarters of the energy contained in the Sun's spectrum into electricity – yet the infrared spectrum is entirely lost in standard solar cells. In contrast, black silicon solar cells are specifically ...
