The first all-Italian quantum cascade laser was born at the National Research Center in Pisa. The protagonists of this milestone are two researchers from the Nanoscience Institute, Lucia Sorba and Miriam Serena Vitiello, who together with their research team designed and developed this innovative device.In fact, quantum cascade lasers have unique potential for detecting gases and other molecules, ...
Conservation of energy is a fundamental concept in physics that can be used to explain anything from planetary orbits to the internal workings of individual atoms.Energy can be converted into other forms, but the overall energy level is usually considered to vary over time. Therefore, when attempting to describe a system, physicists usually pay attention to ensuring that it is isolated from the su...
