Methane resonance

Web10 nov. 2009 · Methane, the major component of natural gas, is highly abundant and its selective oxidation to a liquid form such as methanol would help harness its potential as a petroleum alternative for fuels and in the petrochemical industry. WebIn turn, the variation of the methane gas concentration allows the redirection of the light propagation in the fibre ring resonator. Then, the methane gas concentration can be evaluated by analysing the ratio between the powers of two resonant modes, counter-propagating in the fibre ring resonator.
