Wood, Pamela. "Synthesis and characterisation of Bismuth orthovanadate." Thesis, University of Aberdeen, 1994. http://ethos.bl.uk/OrderDetails.do?uin=uk.bl.ethos.386303.

Full text

Abstract:

A wide range of lime green/yellow to mustard/orange bismuth orthovanadate samples were prepared via solid state and precipitation techniques. The materials were characterised using thermal analysis, X-ray diffraction, evolved gas analysis, reflectance infra-red spectroscopy, electron microscopy, colour measurement, wet chemical analysis and ac impedance spectroscopy. This product characterisation identified more complex materials than previously reported, with generally non-stoichiometric compositions established. The fergusonite-type polymorph of BiVO<sub>4</sub> was prepared via solid state

Abstract:

Several bismuth-containing transition metal perovskites that are of interest as potential multiferroic materials have been synthesised and studied. These materials have been structurally characterised and their physical properties have been examined at varying temperatures and pressures. The new series of substituted bismuth ferrite perovskites BixCa1-xFeO3, where x = 0.4 - 1.0, has been prepared. A disordered cubic phase (x = 0.4 - 0.67) and the coexistence of rhombohedral and cubic phases (x = 0.8 and 0.9) have been observed. The x = 0.8 sample is located at the phase boundary and shows a tr

Nanomaterials (NMs) are materials in which the size of at least one dimension is less than 100 nm. Examples include quantum dots, nanoparticles, “Buckminsterfullerene (C60)”, carbon nanotubes, graphene and TiO2 thin films. Many research groups have investigated the properties of NMs, and they have reported that some of them are clearly different to those of the bulk materials, and depend on the size of the NMs. Examples include melting temperatures, phase transition pressures, fluorescence spectra, catalytic properties and magnetic properties. Recently, a high-pressure study of Te nano-cylinde

Abstract:

The work presented in this thesis focuses on the effect on structure and properties of the rhombohedral (R) perovskite system, Bi(Ti3/8Fe2/8Mg3/8)O3 (BTFM), when solid solutions with CaTiO3 (CTO) are made. Bismuth-based perovskites are established as candidates to replace the piezoelectric material Pb(Zr1-xTix)O3 as they have high Curie and depolarisation temperatures which are necessary for applications and are not toxic. BTFM has a Curie temperature of ~730 °C; however it shows poor electromechanical properties. In Chapter 3 of this thesis is shown that a range of xBTFM-(1-x)CTO compositions

Abstract:

Bismuth nanoparticles (Bi NPs) for use as an X-ray contrast material have gained significant traction in recent years due to the high atomic number and generally accepted biological tolerance of bismuth. However, to be considered a viable candidate for use in this application, water solubility is a necessity, which poses a challenge, since bismuth tends to readily oxidize. For this reason, research into the direct aqueous synthesis of Bi NPs is still in its infancy and can be very difficult, as described in Chapter 1. The remaining chapters of the thesis describe the direct aqueous synthesis o

Abstract:

Nanowires of Zinc oxide and bismuth oxide were grown on silicon substrates using vapor-liquid-solid (VLS) and unbalanced magnetron sputtering. Characterization using x-ray diffraction (XRD) and scanning electron microscopy (SEM) was conducted to investigate how growth conditions influence the structural and morphological properties of the materials. Optical properties were investigated using photoluminescence (PL), direct absorption spectra and cyclic voltammetry. The physical properties of sputtered ZnO were found to be dependent on oxygen flow rate, temperature, and the initial foreign metal

Bismuth based nanomaterials have recently attracted attention as heavy element X-ray contrast agents because of the high atomic number and predicted biological compatibility of bismuth. Nanoparticle X-ray contrast agents may enable a number of novel medical imaging applications, including blood pool and site-directed imaging. However these hypothetical applications are hindered by lack of suitable synthetic methods for production of imaging agents.

Abstract:

During the last years perovskite materials have taken the photovoltaic community by storm, bringing promises of solar cells with efficiencies comparable to conventional silicon devices but at a lower price. However perovskite solar cells so far are facing two main obstacles, they are unstable in the presence of air, moisture and heat and they are usually toxic due to being based on lead-halide materials. This has spurred investigations into alternative materials with similar properties but without the mentioned drawbacks. Just next to Pb in the periodic table is bismuth (Bi) with just one more

Abstract:

Chemical synthesis of materials is facing enormous challenges at the present time. The necessary transition toward more sustainable economic processes requires new materials as well as optimized production of well-established materials. However, inorganic materials (e.g., ceramics or alloys) are typically produced industrially by high-temperature processes at up to 2000 °C. A relatively new approach for inorganic synthesis is based on so-called ionic liquids. Ionic liquids (ILs) — often defined as salts with melting points below 100 °C[1] — are usually composed of sterically demanding organic

Abstract:

De nouveaux complexes carboxylato du bismuth(iii) ont ete synthetises et leur reactivite en oxydation vis-a-vis de substrats test, epoxydes et d'alpha-hydroxycetones, a ete evaluee. Le mandelate de bismuth catalyse la coupure oxydante de ces substrats test en acides carboxyliques. Les reactions sont catalytiques en bismuth et mettent en jeu le couple bi(iii)/bi(o), ce qui est sans precedent en oxydation. L'oxydant est l'oxygene moleculaire dans la transformation des hydroxycetones ; le dmso oxyde les epoxydes en hydroxycetones, le derive du bismuth jouant le role d'acide de lewis dans cette pr

The samples werw judged to be a glass because of the absence in its X-ray diffraction pattern of any strong sharp Bragg scattering peaks. Neither ac susceptibility nor dc electrical resistivity measurements showed any evidence of superconductivity in these glassy samples. The bulk samples with starting composition of Bi2-xPbxSr2CaCu2Oy（x=0,0.2）was prepared by wet mixing of stoichiometric amou

Abstract:

Preparations of (perfluoroaryloxy)bismuth oxide complexes have been undertaken in order to study their reactivity patterns as well as their potential use as precursors to bismuth-containing superconductors via sol gel or CVD processes. The reaction of the dimeric complex (Bi(OC$\sb6$F$\sb5)\sb3$(toluene)$\rbrack\sb2,$ prepared by reaction of BiPh$\sb3$ with HOC$\sb6$F$\sb5$ in refluxing toluene, with NaOC$\sb6$F$\sb5$ in THF yields the hexanuclear complex, $\rm Bi\sb6(O)\sb3(OC\sb6F\sb5)\sb{12}.$ Three sodium-bismuth alkoxide complexes were found. The reaction of BiCl$\sb3$ with three equivale
