Keywords: Oxidation, in situ transmission electron microscope (TEM), Cu2O, morphology
The initial stages of the oxide formation were investigated by oxidizing Cu(100) thin films in a
specialized in situ ultra-high vacuum (UHV) TEM at oxygen partial pressure of 5x10-4 torr and a
temperature range of 150°C to 1000°C.
The experiments were performed at the Materials Research Laboratory, University of Illinois at Urbana-Champaign, which is supported by the U.S.

Sampling.
All chemical analysis results of this study were performed by quality controlling system, which included reagent blanks, replicate samples and certified international reference materials (HRM1 and HRM2 for soils and tailings, HRM12 and HRM14 for plants)[17].
We introduced X-ray diffraction spectrogram into MDI Jade5.0 by computer software, and then selected four PDF card libraries as follows: inorganic materials, minerals, ICSD inorganic materials and ICSD minerals.

In several of these methods, conducting polymers
have been highlighted as effective gas detection materials, since they can operate at room temperature
and have a high sensitivity and good reproducibility.
In the current study, conducting polymer materials were synthesized using a chemical method and 8 kinds of highly sensitive and stable sensors were fabricated on a Al2O3 substrate with interdigital electrodes.
Polymerization of raw materials The polypyrrole and polyaniline were prepared by chemical polymerization based on a previously reported method [13].
Fabrication of sensor The polymer sensor materials (polypyrrole and polyaniline) were made by changing the amounts of additive oxidant (APS), kinds of conducting polymer (polypyrrole and polyaniline), and electrodes, as shown in Table 1.
Sensor manufacturing conditions according to spaces between sensor film materials.

In order to compare the extrudabilities of the investigated alloys, transient simulations were run using the material constants calculated in Table 1.
The calculated constitutive equations were used as input materials data of the alloys, for FE simulation of the extrusion process.
