Team develops new surface design inspired by snake skin

Assistant Professor Seok Kim and graduate students Zining Yang and Jun Kyu Park have developed a design construct inspired in part by the surface of butterflies and snakes, where flexible skins are fully covered by rigid, ...

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 ...

Creating an electron-hole liquid at room temperature

Making a liquid out of electrons is complicated, but it opens the door to research in a wide variety of electronics. NC State physicists have created a phase diagram that can help researchers create this liquid at room temperature, ...

MXene material could improve sensors that sniff

Sensors that sniff out chemicals in the air to warn us about everything from fires to carbon monoxide to drunk drivers to explosive devices hidden in luggage have improved so much that they can even detect diseases on a person's ...

Novel methods of synthesizing quantum dot materials

For quantum dot (QD) materials to perform well in devices such as solar cells, the nanoscale crystals in them need to pack together tightly so that electrons can hop easily from one dot to the next and flow out as current. ...
