Preparation of carbon nanotubes from the controllable flame is a kind of new method. Experimental apparatus is including controllable flame burner, temperature measuring instrument, mass flow meter and catalyst preparation system, etc. The sampling substrate is the growth platform of carbon nanotubes in the flame. The type316 stainless steel is selected as sampling substrate in the experiment. Carbon monoxide provides carbon source and hydrogen/helium premixed gas acts as protection gas. Characterization of the carbon nanotubes on the stainless steel substrate from the controllable flame is by scanning electron microscope (SEM) and transmission electron microscope (TEM). It was found in the experimental that the iron-based catalyst particles are mainly distributed in the ends of the carbon nanotubes. The experimental results reveal that the growth of carbon nanotubes will be very exuberant if the sampling time is controlled within ten minutes.

Web-like carbon nanotubes were synthesized via Laser Ablation Deposition (PLAD) in a T-shape stainless steel chamber. An Nd -YAG laser with a 532 nm wavelength was used to irradiate a target of graphite and a catalyst, with a 5–7 ns pulsed width. Fe2O3 was used as a catalyst to produce a reactive graphite target. The vacuum level was kept at 5 Torr with argon gas flowing from the bottom of the chamber. The plume that was deposited on a glass substrate was then characterized using a Scanning Electron Microscope (SEM), Energy Dispersive X-ray (EDX) analysis, a Transmission Electron Microscope (TEM), and a Vibrating Sample Magnetometer (VSM). Web-like CNT structures were deposited on the glass substrate. These web-like structures were randomly aligned with sizes of 99 nm to 234 nm. TEM images confirmed that these web-like structures were CNTs. VSM results showed that the encapsulation of the Fe2O3 catalyst had influenced the magnetic properties of the CNTs. The magnetic property of CNTs was increased with the increasing amount of the Fe2O3 catalyst filling the CNTs. We assert that the starting catalyst material was transformed from hematite to magnetite via maghemite by a structural change under a reduced oxygen atmosphere during the laser ablation.

Nanocomposite Ni-Al2O3 thin film containing nanosized Al2O3 particles had been grown on steel substrate by ultrasonic-electrodeposited technology. The optimum technological parameters of nanocomposite Ni-Al2O3 thin films were obtained by experiments and analysis. X-ray diffraction analysis was utilized to detect the crystalline and amorphous characteristics of Ni-Al2O3 thin films. The surface morphology and metallurgical structure were analysed by high resolution transmission electron microscope, and scanning electron microscope. The test results showed that nanocomposite Ni-Al2O3 thin films prepared by proper ultrasonic-electrodeposited method consist of nanometer-sized Al2O3 particles and nickel grains. And the Al2O3 nanoparticles and Ni grains diameters in thin films are about 40nm and 80nm, respectively.

Sendzimir Mill

Ti film sputtered on flexible stainless steel substrate that rolled by 20-high Sendzimir Mill, was anodized in ethylene glycol bath in the presence of 0.5 wt.% NH4F and 3 vol.% H2O at a high voltage of 60 V. High-aspect-ratio porous-nanotube arrays (PNTAs) of TiO2 with the tubes length of 6.2 µm were quickly prepared from Ti film, at the high growth rate of 20.7 nm·s-1. Then the morphology and structure of PNTAs were characterized by field emission scanning electron microscope (FESEM) and X-ray diffraction (XRD), respectively. Finally, a DSSC with the photoanode of PNTAs exhibited a performance of Jsc= 2.40 mA·cm-2, Voc= 0.79V, FF = 0.57 and η = 1.08%.

We demonstrated the deposition of the architecture of graphene oxide on stainless steel substrate and its potential environmental application. The synthesis and characterization of graphene oxide were described. The controlled formation of graphene oxide coatings in the form of the homogenous structure on stainless steel is demonstrated by scanning electron microscopy (SEM). The structure, morphology and properties of the material were assessed by Fourier transform infrared (FTIR) spectroscopy, X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, transmission electron microscopy (TEM) and atomic force microscopy (AFM). The morphology and stability of these structures are shown to be particularly related to the pre-treatment of stainless steel substrate before the electrophoretic deposition. This approach opens up a new route to the facile fabrication of advanced electrode coatings with potential use in environmental applications.

Voltammetric Measurements

Polyaniline (PANI) thin films were successfully synthesized from a mixed solution of 1M aniline and two different concentration solutions of H2SO4 on a stainless steel substrate. The capacitance properties of polyaniline (PANI) films, have been determined and examined in the selected media of two different concentrations of H2SO4 acid using cyclic volammetry technique. Cyclic voltammetric measurements have shown that PANI films grown by cycling the potential between -0.2V and 1 V in 1M H2SO4 and 2M H2SO4 on SS electrode. The electrochemical characterization of the electrode was carried out by means of cyclic voltammetry. The results show that polyaniline has a high specific capacitance of 702.1 F.g-1 and 810.5 F.g-1 at 10 mV s-1 in 1M H2SO4 and 2M H2SO4 respectively. This indicates that the promising feasibility of the polyaniline used as an electrochemical capacitor material in the sulphuric acid solutions.

A NiCr/Cr3C2 composite coating with a thickness of approximately 200 m was deposited onto 1Cr18Ni9Ti stainless steel substrate by high-velocity oxy-fuel (HVOF) thermal spraying. Microstructure of the coating was characterized using X-ray diffraction(XRD), scanning electron microscopy(SEM) and transmission electron microscopy (TEM). The coating comprised a NiCr matrix and two types of carbides. The NiCr matrix was composed of an amorphous phase and nanocrystalline grain with a size of 10–50 nm. The microhardness of the coating was found to be 1200Hv, which is significantly greater than that of the stainless steel (1Cr18Ni9Ti) substrate (285 Hv).
