Повний текст джерелаCuvette setup with UV and blue laser as light sources are built to perform photodeposition of metals nanodots (NDs) onto TiO2 nanoparticles (NPs) and Janus-typed Cu2-xS-CuInS2 nano-heterostructures in aqueous and organic solution respectively. Three different metal NDs, i.e., Au, Ag, Pd, are introduced on the surface of TiO2 NPs, and Au NDs are deposited on Cu2-xS/CuInS2. Several techniques, including TEM/HRTEM, EDS mapping, and UV-vis spectroscopy, are performed to characterize the size, morphology, and distribution of the metal NDs. Au-TiO2 nanoheterodimers (NHDs)are successfully synthesized and a close to 100% yield of Au-TiO2 NHDs is achieved by managing the concentration of TiO2 NPs and gold precursor.Especially, the adsorption mechanism of methanol and gold precursor on TiO2 during photodeposition is investigated. By comparing the experimental data obtained in microchannels and cuvette setups, the established model describes the overall dynamic process of Au ND growth on TiO2 from 1/3 growth state to completion. The final size of Au NDs can be accurately predicted by the model in particular the growth completion. In addition, other metal Ag and Pd NPs were deposited on the surface of TiO2, and Ag-TiO2 and Pd-TiO2 NHDs are also synthesized. The effects of the hole scavenger,laser power, and exposure time on the size, and distribution of metal NDs are investigated. Moreover, the growths of Ag and Pd NDs both follow the proposed model for Au growth. The project is extended to bimetallic core-shell NDs photodeposition and Au, Ag and Pd are introduced on Au-TiO2 NHDs by a second step photodeposition, forming a core-shell structure on the surface of TiO2 NPs. For the Au@Au core@shell, the Au shell can be precisely controlled by varying the gold precursor concentration and the size and thickness of the Au core and shell pretty much fit our expectations.For the Au@Ag system, the Ag shell obtained is limited to around 1 nm thickness which results from the low electronegativity of Ag (1.9) compared to other Au (2.4). For the Au@Pd system, Pd shows a non-isotropic growth on the Au core resulting in a nonuniform Pd shell due to the big lattice mismatch between Au and Pd. Finally, Au NDs are introduced onto Cu2-xS/CuInS2 heteronanorods by photodeposition in toluene with a blue laser.The nucleation and growth of Au NDs are studied and the geometric distribution (e.g., number and location) of Au NDs, as well as their sizes, can be well controlled by tuning laser power, exposure time, hole scavengers, and precursors concentration

Повний текст джерелаEl huevo (entero, yema o clara) es un producto natural utilizado desde la antigüedad como medio aglutinante en la pintura al temple, principalmente en Europa y los países de la cuenca mediterránea. Además, el huevo es un complejo sistema multicomponente microestructurado susceptible de ser alterado por los pigmentos que componen las pinturas, así como fuente de nutrientes susceptible de biodeterioro. El efecto de los pigmentos sobre el medio aglutinante, así como el biodeterioro microbiano son responsables de cambios en la estructura y composición del medio aglutinante y, por consiguiente, en las propiedades fisicoquímicas de la pintura. Es por esto que, se utilizaron técnicas analíticas como la Espectroscopía Infrarroja por Transformada de Fourier en modo Reflexión Total Atenuada (FTIR-ATR), para la caracterización química de los procesos de deterioro resultantes de las interacciones pigmento-aglutinante en la pintura al temple. Así mismo, se utilizó Microscopía Electrónica de Emisión de Barrido (FESEM) para el estudio morfológico de las muestras, y para el estudio de las propiedades mecánicas Microscopía de Fuerza Atómica en modo Nanoindentación (AFM-nanoindentación). Por otro lado, la presente investigación propone el uso de la Voltamperometría de Micropartículas (VMP), en conjunto con otras técnicas de análisis como FTIR-ATR, FESEM y AFM-nanoindentación para el estudio del biodeterioro producido por hongos y bacterias sobre una serie muestras pictóricas sometidas. El estudio de las alteraciones causadas por el biodeterioro es complicado por el hecho de que la acción de los microorganismos puede afectar tanto al pigmento como al medio aglutinante. Para esto, se prepararon una serie de muestras de pinturas al temple y emulsión que fueron inoculadas con los hongos Acremonium chrysogenum, Aspergillus niger, Mucor rouxii, Penicillium chrysogenum, y Trichoderma pseudokoningii, y las bacterias Arthrobacter oxydans, Bacillus amyloliquefaciens y Streptomyces cellulofans. El estudio voltamperometrico se realizó utilizando electrodos de grafito modificados con las muestras inmersos en un electrolito acuoso. Las conclusiones obtenidas de manera general, apuntan a que las proteínas presentes en el huevo cambian su estructura secundaria al adherirse a los granos de pigmento. La información química, morfológica y mecánica obtenida por las diferentes técnicas de análisis instrumental es consistente. Finalmente, como resultado del cruce de los datos VMP con los resultados obtenidos mediante FTIR, FESEM y AFM-nanoindentación, las señales voltamperometricas obtenidas se asociaron a la reducción electroquímica de los pigmentos y a los complejos formados con el medio aglutinante. Estos resultados fueron particularmente relevantes en el estudio del biodeterioro de las películas pictóricas inoculadas, para permitir la monitorización electroquímica del ataque microbiológico.
L'ou (sencer, rovell o clara) és un producte natural utilitzat des de l'antiguitat com a mitjà aglutinant en la pintura al tremp, principalment a Europa i els països de la conca mediterrània. A més, l'ou és un complex sistema multicomponent MICROESTRUCTURAT susceptible de ser alterat pels pigments que componen les pintures, així com a font de nutrients susceptible de biodeterioració. L'efecte dels pigments sobre el medi aglutinant, així com el BIODETERIORI microbià són responsables de canvis en l'estructura i composició del medi aglutinant i, per tant, en les propietats fisicoquímiques de la pintura. És per això que, es van utilitzar tècniques analítiques com l'Espectroscòpia Infraroja per Transformada de Fourier en mode Reflexió Total Atenuada (FTIR-ATR), per a la caracterització química dels processos de deteriorament resultants de les interaccions pigment-aglutinant en la pintura al tremp. Així mateix, es va utilitzar Microscòpia Electrònica d'emissió de Rastreig (FESEM) per a l'estudi morfològic de les mostres, i per a l'estudi de les propietats mecàniques Microscòpia de Força Atòmica en mode Nanoindentació (AFM-nanoindentació). D'altra banda, la present investigació proposa l'ús de la Voltamperometría de Micropartícules (VMP), en conjunt amb altres tècniques d'anàlisi, com FTIR-ATR, FESEM i AFM-nanoindentació per a l'estudi de l'biodeterioració produït per fongs i bacteris sobre una sèrie de mostres pictòriques sotmeses. L'estudi de les alteracions causades pel biodeteriori és complicat pel fet que l'acció dels microorganismes pot afectar tant el pigment com al medi aglutinant. Per això, es van preparar una sèrie de mostres de pintures al tremp i emulsió que van ser inoculades amb els fongs Acremonium chrysogenum, Aspergillus niger, Mucor rouxii, Penicillium chrysogenum, i Trichoderma pseudokoningii i els bacteris Arthrobacter oxydans, Bacillus amyloliquefaciens i Streptomyces cellulofans. L'estudi voltamperomètric es va realitzar utilitzant electrodes de grafit modificats amb les mostres immersos en un electròlit aquós. Les conclusions obtingudes de manera general, apunten que les proteïnes presents en l'ou canvien la seva estructura secundària al adherir-se als grans de pigment. La informació química, morfològica i mecànica obtinguda per les diferents tècniques d'anàlisi instrumental és consistent. Finalment, com a resultat de l'encreuament de les dades VMP amb els resultats obtinguts mitjançant FTIR, FESEM i AFM-nanoindentació, els senyals voltamperomètrics obtinguts es van associar a la reducció electroquímica dels pigments i als complexos formats amb el medi aglutinant. Aquests resultats van ser particularment rellevants en l'estudi del biodeteriori de les pel·lícules pictòriques inoculades, per tal de permetre la monitorització electroquímica de l'atac microbiològic.

Повний текст джерелаTwo kinds of metallic transparent and conductive oxides - SnO2 and CdIn2O4 - have been deposited in thin films using the aerosol pyrolysis technique. They have been used as semi-conductor electrodes in view of the label-free electrochemical detection of DNA hybridization. The deposition conditions have been modified in order to obtain films exhibiting different characteristic. The correlations between micro structural and electrical properties of the as-deposited electrodes and their sensitivity to DNA hybridization have been particularly studied. The major result shows that the sensitivity to DNA hybridization of the studied semi-conductor electrodes is linked to the electrical resistivity of the electrodes. This is particularly true in the case of Cdln2O4 films, the microstructure of which exhibiting nearly no evolution. Ln contrast, in the case of the SnO2 films, the microstructure is an important parameter as well as the electrical resistivity

Повний текст джерелаAs a tool for controlling the Municipal Solid Waste (MSW) incineration process and its possible pollutant emissions, a mathematical model of the MSW bed burning on travelling grate of an incinerator was developed. The model describes most of the physico-chemical and thermal phenomena taking place in incineration like the drying and pyrolysis of the feed, combustion and gasification of char, oxidation of pyrolysis gases, heat transfer, bed shrinking, feed stirring, etc. Also described in the model are the mechanisms of Heavy Metals (HM) volatilization and NOx formation. Kinetics of HM release was modelled using the approach of additive reaction times accounting for the various transport mechanisms involved: external transfer, intra-particle diffusion and actual volatilization. In the case simulated, i.e. of Cd, almost total volatilization is predicted, which is confirmed by literature findings. The NOx sub-model takes into account most of the common mechanisms of formation like thermal, prompt, fuel, N2O intermediate and also NOx reduction by homogeneous reburning and heterogeneous reduction by char. Calculations show that NOx formation is predominated by the fuel mechanism and destruction by the heterogeneous reduction. Finally, the bed model was applied to study the influence of various operating parameters like flow rate, temperature and distribution of air under grates, waste particle size, feed stirring and the stirring scheme. The results are presented and discussed in detail and the influence of operating conditions on process efficiency and on emissions of Cd and NOx is analyzed

In this thesis, rice (Oryza sativa L., cv. Taichung Native 1, TN1) seedlings were used to investigate the effect of nitric oxide (NO) on the toxicity of roots caused by cadmium. Cadmium treatment significantly inhibited plant height, root length, fresh weight and dry weight, as well as cadmium content in cadmium-treated shoots and roots increased with prolonged duration of incubation. In plants, NO is involved in many physiological responses, such as defense response to biotic and abiotic stress. In this study, 10μM SNP (NO donor) pretreatment significantly recovers cadmium inhibited root length, fresh weight and dry weight of rice root, and decrease oxidative stress induced by cadmium. It is clearly that NO decreased malonaldehyde and hydrogen peroxide content of rice roots induced by cadmium. SNP-treated roots decreased with SOD and POD activity, but increased with CAT activity. However, SNP pretreatment is not decreased in cadmium content, it is increasing. It is demonstrate that SNP-pretreated caused antioxidative enzymes activity decrease in cadmium toxicity and recover rice seedlings growth, as well as not uptake cadmium content.

The objective of this research is to develop the adsorptive material through specific synthetic process. Synthetic processes were divided into two reaction systems, including citrate/Fe(III) and silicate/Fe(III) solutions. And the synthetic conditions of citrate/Fe(III) and silicate/Fe(III) solutions were controlled at pH=8.0, 25℃ and N2 environment. Surface characteristics and microstructures of synthetic iron oxide were investigated, and the adsorption characteristics for metal ions removal were evaluated from water. The quantity of citrate or silicate in synthetic solution was found to have a noticeable effect on the pore size distribution for synthetic iron oxide. Moreover, the macro pores on the surface of synthetic iron oxide decreased after adsorbing cadmium ions. This result indicated that cadmium ions could transport and diffuse into the macro pores on synthetic iron oxide surface, and caused the adsorption reaction. According to XRD analysis result, there was no specific absorption peak appearance on the sample of synthetic iron oxide through the synthetic process under the pure Fe(III) or 0.1 molar ratio of silicate/Fe(III) solution at pH=8.0. The mineralogy of synthetic material prepared by this procedure was verified to be the amorphous iron oxide. However, the mineralogy of synthetic material belonged to the crystalline magnetite through a 0.1 molar ratio of citrate/Fe(III) solution at pH=8.0. Results of kinetic adsorption experiments showed that the best adsorption capabilities of adsorptive material were synthesized under the conditions of 0.1 and 1.0 molar ratio for citrate/Fe(III) and silicate/Fe(III), respectively. And the adsorption efficiencies of cadmium ions for two synthetic materials reached 50~90% and 50~60% at Cd(II)=1.0×10-4M、2.5×10-4M and 5.0×10-4M, pH=6.0, respectively. FTIR analysis result showed that there was a specific absorption peak appearance on iron oxide after reacting with cadmium ions. This result inferred that the adsorptive reaction belonged to form chemical bonding between cadmium ions and iron oxide surface.
