Musical sensor shows bad medicine plays false note

Inspired by a musical instrument, the simple sensor can be constructed from common materials and used to detect adulterated or counterfeit drugs

17-Sep-2018

What if a single musical note could mean the difference between life and death? A new sensor based on a 3,000 year old African musical instrument can be used to identify substances, including a poisonous chemical sometimes mistakenly added to medicines. The mbira sensor, which can be constructed ...

A better way to control crystal vibrations

23-May-2018

The vibrational motion of an atom in a crystal propagates to neighboring atoms, which leads to wavelike propagation of the vibrations throughout the crystal. The way in which these natural vibrations travel through the crystalline structure determine fundamental properties of the material. For ...

Giant charge reversal observed for the first time

14-Jul-2017

Charged surfaces submerged in an electrolyte solution can sometimes become oppositely charged. This nonintuitive phenomenon, known as charge inversion, happens when excess counter ions adsorb, or adhere, to the surface. It can occur in a number of chemical and biological settings. In certain ...
