Toluene removal is investigated in filamentary plasmas produced in N2 and in N2/O2 mixtures by a pulse high voltage energised DBD. Influence of the oxygen percentage (lower than 10%) and of the temperature (lower than 350°C) is examined. Toluene is

A photo-triggered discharge is used to study the influence of three hydrocarbons (HCs), propene (C3H6), n-decane (C10H22), and toluene (C6H5CH3) on NO conversion in N2/O2/NO/HC mixtures, with 18.5% O2 concentration, 700 ppm of NO, and an hydrocarbon

Brillouin scattering of light originates from the interaction of an incident radiation with thermal acoustic vibrations in matter and probes the long-wavelength acoustic phonons. In this chapter, calculations of the sound velocities and scattered int

Sensors based on optical fibers have well known advantages over conventional electromechanical sensors. They offer electrically passive operation and immunity from electromagnetic fields because the fiber is entirely made with dielectric materials. W

Earlier work on the vibrations of fractals is extended and a firmer formal basis is constructed which should help in comparing detailed dynamic scaling assumptions to simulations and experiments. We show how the strong scattering assumption: that the

A new method for the accurate measurement of Brillouin line shifts is presented. By modulating a reference beam at a microwave frequency corresponding exactly to the shift of the Brillouin line, the Brillouin scattering frequency is obtained by direc
