Light-induced symmetric changes in small crystals allow researchers to create materials with customized properties
An artistic illustration of lead sulfide quantum dots when lead atoms temporarily move to a new position and undergo structural changes when exposed to light. Credit: Cotz Lab, Middlebury College. Imagine building a Lego Tower with perfectly aligned blocks. Each block represents a small crystal atom known as a quantum dot. When you hit a tower, external forces can shift…

Nanogates use voltage to control the passage of molecules through small pores
A schematic model depicting single molecule DNA via nanoprecipitated nanopores. Credit: Makusu Tsutsui The collaboration, led by researchers at Osaka University, has developed a nanogate that can be opened and closed by applying electricity. Nanogates exhibit a variety of behavior depending on the material in the solution on either side of the gate and the applied voltage, making them attractive…
