Although carbon nanotubes have been shown to be excellent field emitters, very little is known about the emission mechanism. This work strives to gain insight on field enhancement in films of single-walled carbon nanotubes by studying the internal field emission between the back contact metal and the nanotubes, and the external field emission between the nanotubes and vacuum. Test devices of different work functions were fabricated from platinum and from nickel / nickel oxide. Nickel oxide was deposited by e-beam evaporation or grown by thermal oxidation and characterized by Auger electron spectroscopy, x-ray diffraction and ellipsometry. Carbon nanotubes were deposited onto these test structures and current-voltage measurements were taken. Fowler-Nordheim plots were constructed from this data and analyzed. It was determined that external field emission was most likely to be responsible for electron emission.

The steam methane reforming (SMR) reaction is the primary industrial means for producing hydrogen gas. As such, it is a critical support process for applications including petrochemical processing and ammonia synthesis. In addition, SMR could be an important component of future energy infrastructures as a means for producing hydrogen as an energy carrier for applications including fuel cells in automobiles and direct combustion for electricity generation. Nickel is the preferred SMR catalyst; however, the efficiency of SMR over nickel can be severely hindered by carbon formation, which leads to the deactivation or even destruction of the catalyst particles. Thus, there is significant interest in catalysts that inhibit carbon formation yet retain activity to SMR. In order to develop improved catalysts for SMR, a thorough understanding of the processes occurring on the nickel surface is needed. In this thesis, computational heterogeneous catalysis is applied to investigate steam methane reforming over nickel (Ni) and silver-alloyed nickel (Ni/Ag) catalysts. Electronic structure calculations using density functional theory (DFT) are employed to develop thermochemical landscapes describing the relative stabilities of SMR intermediates on the catalyst surfaces. In addition, DFT calculations are used to obtain kinetic parameters that describe elementary surface reactions taking place during SMR. A detailed statistical thermodynamics framework is developed to allow for the calculation of enthalpies, entropies, and free energies of the surface species at the temperatures and pressures relevant to industrial SMR. The data from the DFT calculations are used to build detailed ab inito microkinetic models of SMR over the multi-faceted nickel catalyst. The resulting microkinetic models are used to provide insight into the processes occurring on the catalyst surface through identifying the most important intermediate species and reactions occurring on the catalyst. The effects of alloying the nickel catalyst with silver are predicted through modeling the dissociative methane adsorption reaction on multiple facets of the Ni/Ag surface with varying concentrations of silver. In addition, DFT calculations are used to investigate carbon formation on the Ni and Ni/Ag catalyst surfaces, including relative stabilities of various carbon-containing intermediates and the effects of alloying the nickel surface with silver on carbon formation.

Pełny tekst źródłaUltrasonic shot peening is widely used to improve mechanical properties of metallic components. Mastering the effects of this surface treatment is a major industrial issue. A physical multi-scale modelling based on crystal plasticity and DEM (Discrete Element Model) was developed in this PhD thesis. This process is performed in a closed chamber where spherical balls are moved by sonotrode vibration. Thousands of impacts induce hardening, residual compressive stress and microstructure modification leading to a nanostructured layer. The aim of this work was to improve our understanding of the mechanisms occurring during this process on nickel-based alloys. Ball motion was computed by DEM and linked to microstructure modifications induced by impacts through a crystal plasticity finite element model. Experimental analyses were performed in order to validate each step of the multi-scale modelling. Then the model was applied to investigate ball quantity effects on peened surface modification. Increasing the number of balls created a larger quantity of low speed oblique impacts which concentrated the residual compressive stress near the surface. Furthermore multi-impacts performed with a crystal plasticity law showed oblique impacts enhanced dislocation storage and disorientations within grains, which could explain the nanostructuration of the peened surface. Moreover, the numerical microstructure modification, observed up to 300 µm in depth, was in agreement with hardness profiles obtained by nanoindentation and disorientation profiles measured by EBSD (Electron BackScatter Diffraction) analysis

Pełny tekst źródłaIt was found that this reject material can successfully be treated using a carbothermic reduction process to produce 50 to 75 mum diameter metallic components within a gangue matrix. The recovery of nickel ranged from 61.7% to 21.9% to 16.4% in the high, low and non magnetic fractions, respectively, separated from the reduced material. The grade of nickel ranged from 1.97 wt% Ni to 1.58% to 0.75 wt% Ni in the high, low and non magnetic fractions, respectively.
Heating temperature had the greatest positive influence on the performance of the process followed by material type and heating time. Oxygen activity and coke addition were seen not to influence the performance. The Boudouard reaction was considered to be the rate controlling step and a maximum possible operating temperature was considered to depend on the physical properties of the material, specifically the softening temperature.

This thesis mainly focuses on studies of the synthesis of stable FCC and HCP Ni nanoparticle (NPs) and their transformation to nickel phosphides and nickel Sulfides NPs. Synthesis of colloid hollow Ni2P NPs can be via a simple one-pot reaction with nickel acetate (Ni(Ac)2), oleylamine (OLA), trioctylphosphine (TOP), and 1-octadecene (1-ODE) as reactants. The mechanism of formation of the hollow structure is related to the diffusion mechnaism, the nano-scale Kirkendall effect. The whole process includes two key points. First, the existence of OLA ensures the nickel NPs stabilized, which forms protecting layers on the surface of NPs and prevents the erosion from TOP, and reduce diffusion rate of P atoms. Second, when the concentration of TOP and temperature are adjusted and controlled properly, the solid state reaction will take place and lead to the formation of hollow Ni2P nanoparticles. Synthesis of HCP phase Ni NPs with star-shaped and spherical morphology are both through thermal decomposition method, but using different precursors, namely, nickel acetate and nickel acetylacetonate (Ni(acac)2). The different precursors may have different decomposition rate that could affect the monomers concentration during the reaction. By using the precursor of Ni(Ac)2, the star-shaped HCP Ni NPs were obtained by anisotropic growth in the high monomers concentration, while using Ni(acac)2, spherical HCP Ni NPs were obtained. The size of NPs can be controlled through the different reaction times. Also, the obtained HCP Ni NPs can be differentiated from Ni3C by temperature-dependent powder X-ray experiments. Magnetic properties of the obtained HCP Ni NPs were also carried out on SQUID. The results indicated the HCP Ni is not as ferromagnetic as FCC Ni; it is nonmagnetic. Furthermore, the star-shaped HCP Ni particles can be also transformed to Ni2P and Ni9S8 via the diffusion reaction using trioctylphosphine and 1-hexadecanethiol.

Abstract We are using dynamic methods:ring-disk and pulse current technologys toanalyse the contents of Ni-Fe, Ni-Cr, and Ni-Cr-P alloys. Ni-Fe plating was carried out using the rotating ring-disk electrode under different operating conditions. Various ferrous ion concentrations, bath pH values, and additives were used in the plating baths to study their influences on themetal deposition rates and alloy compositions. Experimental results indicate that the nickel plating rate decreases withthe increase of ferrous ion concentration. Iron and nickel current density increase with an increased bath pH value. Citrate ion inhibits both nickel and iron reduction rate. Ni-Cr and Ni-Cr-P alloys plating were carried out using galvanostatic pulse technique on the rotating disk electrode under different operating conditions were to study the effect of pulse parameter on the metal deposition rate, alloy composition and surface morphology. Results indicate that similar results are obtained for both Ni- Cr and Ni-Cr-P platings. The influence of disk rotation speed on nickel plating rate is different at low and high duty cycles. In low duty cycle region, nickel plating rate decreases with an increase of rotation speed.In high duty cycle region, nickel deposition rate increases at an increased disk rotation speed. Disc rotation speed has a positive effect on chrome and phosphorus deposition rates. Nickel deposition rate increases while chrome deposition rate decreases with an increased bath pH value. Nickel and phosphorus deposition rate increases while chrome deposition rate decreases with an increase of pulse frequency. Chrome and phosphorus deposition rate are enhanced with an increase of pulse current density. Nickel deposition rate is decreased at an increased pulse current density in high duty cycle region. Alloys surface morphology was studied by scanning electron micrograph. X-ray diffraction was used to study the noncrystal structure of the resulting deposits.
