Soon, we may be able to do more with fallen tree leaves than just rake them and clean them up: a team in Brazil has developed a new approach using a CO2 laser that transforms leaves into electrochemical sensors.
The PASSEPARTOUT project, meant to facilitate the design of photonic-based gas analyzers to monitor air pollution, is taking another step forward with the development of a miniature hyperspectral optical sensor that combines several spectroscopy techniques.
While testing a new spectroscopy approach—electric-field tip-enhanced strong coupling—researchers in Korea have discovered it’s possible to electrically control polaritonic states, even at room temperature. This could offer a better understanding of quantum electrodynamics.
