We have added time resolution to laser-induced breakdown spectroscopy in two
forms, by gating an optical multichannel analyzer (OMA) and by time-resolving
the output of a photomultiplier with a boxcar amplifier. Spectra were obtained
for temporal segments of 25 to 100 ns, from 25 ns to 50 µs after initiation of
the breakdown. OMA spectra of oxygen illustrate the power of this technique for

The combination of plasma discharge and adsorption was examined for oxidation of
dilute benzene in air in a plasma reactor packed with a mixture of BaTiO 3
pellets and porous Al 2 O 3 pellets (i.e., an alumina hybrid reactor). The
oxidative decomposition of benzene was enhanced by the benzene concentrating on
the Al 2 O 3 pellets. Furthermore, there was a higher selectivity to CO 2 in the
products... hiện toàn bộ
