A team of researchers affiliated with several institutions in Austria and Germany has shown that introducing environmental noise to a line of ions can lead to enhanced transport of energy across them. In their paper published ...
With a growing global population will come increased energy consumption, and sustainable forms of energy sources such as solar fuels and solar electricity will be in even greater demand. And as these forms of power proliferate, ...
