Texto completoThe interaction between electrons and phonons in condensed matter is responsible for the coupling of their transport equations, which gives rise to mutual drag effects between them under the effect of a temperature gradient (Seebeck effect) or a charge current (Peltier effect). In some bulk materials, these drag effects, better known as “phonon drag”, lead to very high Seebeck coefficient values at low temperatures. It usually manifests at low temperatures when the phonon mean free path is large, near the maximum in temperature of the lattice thermal conductivity in dielectric crystals, which occurs due to reduced phonon-phonon scattering. Historically, phonon drag has been overlooked in thermoelectric research as it coincides with the maximum in the lattice thermal conductivity peak, potentially reducing overall thermoelectric efficiency. However, studies in 2008 on nanostructured silicon systems contradicted this, demonstrating that significant Seebeck effects from phonon drag can coexist with low lattice thermal conductivity. Theoretical works treating the coupled transport equations offered new insights, demonstrating that phonon states dominating heat transport are distinct in phase space, in wave-vector, and energy from those mainly involved in drag effects. The aim of my thesis was to carry out experiments to explore a novel concept of phonon drag between electron and phonon gases, separated by an interface. I studied transport properties of electrons confined to a conductive channel beneath the surface of a crystalline diamond acting as an external phonon bath with propagative phonon states. My thesis involved system construction, structural characterization, development of measurement protocols for conductance and Seebeck coefficients, and adaptation of these measurements for buried conductive systems. I analyzed the transport properties of channels produced under different implantation and annealing conditions to understand how the microstructure of the channel influences electronic transport properties. In the first study, I measured conductance and the Seebeck coefficient in thick channels (~145 nm) buried about 200 nm below the diamond surface. These channels, created via helium ion implantation at moderate fluence followed by high-temperature annealing, displayed mostly a graphitic microstructure. At room temperature, the conductance was close to that of bulk graphite. The Seebeck coefficient exhibited low-temperature behavior akin to graphite, with a negative peak attributed to drag effects. However, this peak occurred at a significantly higher temperature compared to solid graphite, which could be a first indication of additional contributions from diamond phonons. In the second study, I examined channels with similar dimensions but subjected to lower implantation fluence or annealed at lower temperatures. These channels exhibited a highly disordered microstructure composed of aggregates of carbon atoms with sp, sp², and sp³ hybridization. The temperature-dependent conductance and Seebeck coefficient varied significantly from the first study. The Seebeck coefficient is positive and reached several thousand µV/K at low temperatures. The transport properties were interpreted using quantum chaos theory. My work shows the feasibility of conductance and Seebeck coefficient measurements at low temperature through conductive channels buried beneath the diamond surface and highlights the rich conduction properties of such channels which can be tuned by controlling their microstructure through a careful choice of implantation and annealing parameters

Resumo: O desenvolvimento de novos materiais para a produção de implantes ortopédicos tem sido uma busca constante, devido principalmente ao aumento das aplicações clínicas e à necessidade de se alcançar maior durabilidade, diminuindo assim as cirurgias de revisão. O diamante CVD obtido por deposição química da fase vapor é um novo material com grande potencial de uso devido às suas excelentes propriedades físico-químicas. Dentre elas pode-se destacar a inércia química, extrema dureza e baixo coeficiente de atrito, características importantes para materiais que necessitam resistir ao desgaste e à corrosão produzida pelos fluídos do corpo humano. O objetivo deste estudo foi avaliar pela análise ¿in vitro¿ e ¿in vivo¿ a biocompatibilidade de tubos de diamante microcristalino e diamante nanocristalino produzidos pela deposição química de vapor em filamento quente (CVD). Palavras Chave: diamante CVD, biomateriais, implantes, próteses

Texto completoBoron doped diamond (BDD) electrodes are extremely promising in the field of biomedical applications as they exhibit a unique combination of properties. The thesis aims at developing new types of BDD microelectrodes and exploring their interests for electro-analytical and electrophysiological applications. Despite their superior electro-analytical properties, BDD electrodes are prone to fouling, which leads to a loss of electrode reactivity when used in biological fluids such as urine, waste waters, drinks, blood plasma, etc. A novel electrochemical treatment was developed to clean the electrode surface and to retrieve the initial reactivity, thereby enabling the use of BDD electrodes to long periods of measurements without degradation of the signal, thus significantly extending the field of monitoring and surveying applications up to domains where continuous analysis is required. The real novelty of the technique is that it does not require the use of a specific media and thus can be directly performed in the probed (bio-)fluid. Microelectrodes in comparison with macro-electrodes offer higher sensitivity, lower background current, lower ohmic losses and higher signal-to-noise ratio. A robust, high-yield, reliable, and reproducible process for fabricating a thin-film BDD micro and ultra-microelectrode arrays (MEA) was developed using a novel lithographic technique, based on clean room processing on 4 inch substrates, thus offering wide flexibility. For example, among other prototypes, BDD microelectrodes were developed as biosensors to quantify uric acid in human urine in quasi-real time. Although diamond film possesses good biocompatibility and excellent electrochemical properties, the low double-layer capacitance limits its application in electrophysiological applications. Increasing the charge injection limit was investigated by surface modification and nano-structuring. These include the synthesis of hybrid diamond-polypyrrole electrodes and nanograss BDD MEAs. Such high aspect ratio materials appear as excellent candidates for neurointerfacing applications such as for retinal implants

Texto completoPurpose: To evaluate the interface abutment/implant, and the loosening screws values when used screws with Diamond-like carbon (DLC) coated and conventional titanium screws for fixation of prosthetic components, before and after action of cyclic loading. After, to evaluate the connections between the values of interface abutment UCLA/implant and loosening screw. Method: Thirty six implants were divided into four groups according to the type connection (external hexagon and internal hexagon) and screw used to fix the abutment to the implant (titanium or coated with DLC): Group A: external hexagon / titanium screw; Group B: external hexagon / DLC screw; Group C: internal hexagon / titanium screw; Group D: internal hexagon / DLC screw. After the implants were included in colorless acrylic resin, crowns were waxed using UCLA type abutment, casting with metal alloy of Ni-Cr-Ti and screwed to the implants using the torque recommended by the manufacturer. Then the interfaces pillar/implant were measured with light microscope in four pre-marked points (DV1). After the sets (implant, crown and screw) were subjected to one million mechanical cycles and the interfaces measured again (DV2). Analysis of Variance, Test t Student and test Mann Whitney (p≤0,05) were applied to compare the average to the interfaces abutment/implant intra and intergroup, the difference between the same and the loosening screws values. And to evaluate the correlated between the factors studying, the Pearsons correlation test (p≤0,05). Results: The implants with external hexagon exhibited the higher values of the vertical misfit pillar UCLA/implant before (DV1) and after (DV2) cyclic loading (GA/DV1 = 59,81μm e GA/DV2 = 62,59μm, GB/DV1 = 73,73μm e GB/DV2 = 72,95μm). In groups of titanium shows screws there was an increase in interface abutment/implant after cyclic loading (GA = 59,81μm to 62,50μm and GC = 18,13μm to 22,54μm) and in groups with DLC coated screws there was a reduction the values of interface abutment/implant (GB = 73,73μm to 72,95μm and GD = 16,07μm to 14,47μm). Only group C showed a statistically significant difference to the interface abutment/implant before and after cyclic loading (p = 0.05) exhibited mean values and differences between the interfaces pillar/implant. To correlate the values of loosening to the values of pillar interfaces/implant was applied the Pearsons correlation test, but there was no significance among the studied factors (p ˃ 0.05). Conclusions: The interfaces pillar UCLA/implant were higher in groups with external hexagon connection those in groups with internal hexagon, but without significant differences when use titanium screws or coated with DLC. Always screws loosed torque after cycling load. Is not possible to affirm that a higher value of interface abutment/implant be correlated with the loosening screw.

Texto completoDental implants are artificial fixtures that are surgically inserted into the jaws to replace missing teeth. The success of dental implant treatment is dependent on achieving successful osseointegration (Branemark et al. 2001). Drills used for implant site preparation are made of different materials such as stainless steel (SS), zirconia and ceramic. Most of them do not have sufficient cutting efficiency and wear resistance (Oliveira et al. 2012). Recently diamond-like carbon coating (DLC) has been added as a drill coating to increase the cutting efficiency, increase wear resistance and drill hardness (Batista Mends et al. 2014).
