Glasses generate power with flexible organic solar cells

Organic solar cells are flexible, transparent and lightweight, and can be manufactured in arbitrary shapes or colors. Thus, they are suitable for a variety of applications that cannot be realized with conventional silicon ...

Building miniature optical antennas using DNA as a guide

An international research collaborative has reported a new, highly parallel technique to fabricate precise metallic nanostructures with designed plasmonic properties by means of self-assembled DNA origami shapes. The so-called ...

Means by which cells 'eat' silicon nanowire revealed

(Phys.org)—A team of researchers at the University of Chicago has developed new technology that allows for recording and viewing the process by which a silicon nanowire is consumed by an individual cell. In their paper ...

Control over friction, from small to large scales

Friction is hard to predict and control, especially since surfaces that come in contact are rarely perfectly flat. New experiments demonstrate that the amount of friction between two silicon surfaces, even at large scales, ...

As Facebook's grown, so have its challenges

In 2011 as Facebook inched ever closer to 1 billion active monthly users, it faced a vexing crisis: uproar about a facial recognition algorithm that tagged people in photos without their consent.
