This research examines the metallorganic chemical vapor deposition process using tetrakis(3-methyl-3-pentoxy)cerium, Ce [OC (C2 H5) 2 CH3] 4, as a source material to prepare CeO2 films by two different mass spectrometric techniques: ionization by Li+ ion attachment and electron impact. The reaction by-products of (C 2 H5) 2 C CH2 and H2 O, respectively resulting from the pyrolysis of the source material and the dehydration reaction at the sticking of the precursor on the substrate surface, were detected as a result of the simple reaction integrated as Ce [OC (C 2 H5) 2 CH3] 4 → CeO2 +2 H2 O+4 (C2 H5) 2 C CH2. The deposition was controlled by two mechanisms: desorption of the adsorbate from the surface site with the activation energy (Ea) =0.85 eV and decomposition of the source material with that of Ea =0.29 eV. © 2009 The Electrochemical Society.

A method and an apparatus capable of selectively damaging and killing tumor cells includes a step of irradiating tumor cells with a UV pulse flash having continuous emission spectra ranging at least from 230 to 270 nm, outside a living body of a human or a living body of a non-human animal or in a living body of a non-human animal. The UV pulse flash may have an accumulated irradiation amount per unit area that is achieved at a distance of 8 cm from a light source having an integrated output of, for example, 90, 180-7100 or 14200 J.
