Abstract: A photoacoustic gas sensor includes a hermetically sealed housing filled with a reference gas. The photoacoustic gas sensor furthermore includes a microphone arranged in the housing and configured to generate a microphone signal as a function of a sound wave based on light incident in the housing. Furthermore, the photoacoustic gas sensor includes a controllable heat source arranged in the housing and configured to selectively thermoacoustically excite the reference gas in order to generate a thermoacoustic sound wave phase-shifted with respect to the sound wave.

Abstract: There are provided methods and systems for an electrochemical cell including an anode and a cathode where the anode is contacted with a metal ion that converts the metal ion from a lower oxidation state to a higher oxidation state. The metal ion in the higher oxidation state is reacted with hydrogen gas, an unsaturated hydrocarbon, and/or a saturated hydrocarbon to form products.
