Lately, Dai et al. also reported the results of retarded charge recombination in dye-sensitized nitrogen-doped TiO2 solar sells.[10] They prepared the N-doped titian using sol-gel method and discussed the mechanism of charge recombination of DSCs based on nitrogen-doped TiO2 electrodes.
They also carried out the stability test under one sun light soaking and a high temperature condition (70 °C) for more than 1000 hs, they observed that the DSC based on the N-doped TiO2 photoanode is more stable than that of undoped TiO2.[10] These results are consistent with those of our group.[9] Yang et al. designed a device to generate TiNxO2-x powders using NH3 as a gaseous precursor
Recently, Dai et el. also carried out the stability test of the DSCs based on the N-doped titania.

Hilleret el al. reported that secondary electron yield of an air exposed ZnO film decreased after annealing the film [9].
Shima et al. performed Kelvin probe force microscopy and micro X-ray photoelectron spectroscopy measurements on the LRS of a CoO film which was written by the voltage application using C-AFM [6].

Pomery, et al. reported the oxidation process of Si3N4 based materials in air at 1300°C and different times [4], Balls Features Si3N4 (Standard) Si3N4 (High Degree) Notation Si3N4 (S) Si3N4 (HD) Diameter [mm] 9.51 7.93 Area of ball [cm 2 ] 2.841 1.976 Density [g/cm 3] 3.23 3.24 Weight average [g] 1.456 0.846 Table 1.
Pomery, et al. [4] argued that the oxidation process of silicon nitride is influenced both by the amount of porosity and the material's surface structure, being the open pores the place where the oxidation process begins.
