Повний текст джерелаThe objective of this work is the study of the transport through lipid membranes of water and ions using self-assembled artificial channel structures and the design of nano sized self-assembled organic contacts for macroscale applications: biocathodes.The first part focuses on the transport through membrane bilayers. The objective is to replicate the function of naturally occurring proteins using ureido-hetreocycle compounds. The influence of species composition is assessed versus the supramolecular structure it generates and the link between it and activity. The first chapter treats the transport of ions through the lipid bilayers of large unilamellar vesicles (LUVs), in terms of total activity and selectivity vs. the structure of compounds. The second chapter refers to the transport of water on LUV systems. Here, a combined approach was used in evaluating the channels' activity, by placing them both on the outside of the liposomes but also directly in the lipid layer. Finally the protons transport of these structures was assessed reveling very efficient proton channels. The third chapter has an interdisciplinary approach combining several topics. The triaryl amines (TAAs) have to propriety of forming self-assembled nano sized fibrils when irradiated by the generation of cation-radicals. These present a directional electronic conduction pathway and are reported to display metal-like conductivity. These fibrils, which unravel in the absence of light, provide interesting possibilities as organic nano scale electrical contacts. A matrix of mesoporous silica was created via electrodeposition in order to enclose the TAAs in a confined medium. The novelty of the approach is that the system only has electron conductivity trough the TAAs nano wires while the silica mass is insulating. The resulting device's proprieties were characterized and further it was used as a bio cathode. The biocathodes containing the enzyme Laccase were then tested to prove the functioning of the matrix of nano contacts as the only providers of electrons to the enzyme

Повний текст джерелаDuring this thesis, we have proposed theoretical and numerical methods to study the behavior of electrons in periodic materials, with a particular interest for 2D materials, like graphene, and topological insulators. The thesis consists in three parts, organized as follows.The first part provides a mathematically proven and simple algorithm to build localized Wannier functions, with the only requirement that the system has vanishing Chern numbers. Based on an explicit and constructive proof of homotopies for the unitary group, the algorithm is able to build localized Wannier for topological insulators such as the Kane-Mele model. The method is validated by numerical tests for several systems.In the second part, we propose an approximation method for Wannier functions that is adapted to the computation of tight-binding Hamiltonians in non-periodic van der Waals heterostructures, that is, layers of 2D materials stacked on top of each other, bound together by the comparatively weak van der Waals forces. This setting is challenging for the usual computational tools of solid-state physics, which rely on the periodicity of crystals. In this context, a first-order approximation is to consider the Wannier functions computed on each layer independently. We therefore propose an approximation scheme for Wannier functions that allows for an efficient computation of tight-binding matrix coefficients, even in the non-periodic case.The third part is theoretical and devoted to the study of independent electrons in a periodic crystal in their ground state, set in motion by a uniform electric field at some prescribed time. We rigorously define the current per unit volume and study its properties using both linear response and adiabatic theory. Our results provide a unified framework for various phenomena such as the quantification of Hall conductivity of insulators with broken time-reversibility, the ballistic regime of electrons in metals, Bloch oscillations in the long-time response of metals, and the static conductivity of graphene

Повний текст джерелаCurrently,layered materials attract great interest due to their electrical and optical properties. Such crystals display an electronic band structure that strongly depends on the sample thickness.The large tunability of the electronic screening and gap size can be very attracting for the creation of heterostructures whose properties can be designed on demand. We can say that the research field of low dimensional materials has been boosted by the discovery of graphene and quickly has been enlarged to other materials as transition metal dichalcogenides,black phosphorous and Indium selenide.Our work will focus on the excited state dynamics in these compounds,as well as on the evolution of the band structure upon surface doping.The manuscript is organized as follow:Chapter1 provides a general introduction of layered materials.In particular,we discuss the structural and electronic properties of some relevant compounds.Chapter2 describes the principles of ultrafast spectroscopic methods and shows many applications to the case of the layered materials.We mainly focus our attention on the electron dynamics in semiconducting crystals and charge density waves systems. The electron dynamics of layered materials have been investigated by means of time-and angle-resolved photoelectron spectroscopy (TrARPES),which is a powerful tool to directly map the electronic band structure and to follow the dynamics of the electrons photoinjected via an ultrafast laser source.Chapter3 discusses the experimental technique of choice and the setup where we have been performed in the reported measurements.we begin the discussion of our original data in Chapter4.The TrARPES measurements of layered black phosphorus(BP) monitor the electronic distribution in the conduction and valence band as a function of delay time from photoexcitation.The data show that,after thermalization,the photo-injected electrons do not lead to sizable band gap renormalization,neither do they generate an appreciable amount of carrier multiplication.On the other hand,a Stark broadening of the valence band is ascribed to the inhomogeneous screening of a local potential around charge defects.Chapter5 shows time resolved ARPES data on a BP surface that is doped in-situ by means of alkali metals evaporation. We monitor the collapse of the band-gap in the accumulation layer with unmatched accuracy and we observe that the buried states detected by the low energy photons of our probing pulse acquire a surprisingly high band velocity at large dopants concentration.Chapter6 deals with the modification of hot carrier dynamics upon increasing the surface doping of BP.In this case the reported analysis is still preliminary and needs to be backed by ab-initio calculations.Chapter7 contains our work on layered ɛ-InSe.As in the case of BP,we generate an accumulation layer of varying electronic density on the surface of such semiconductor.By spanning the doping level from the semiconducting to the metallic limit,we observe that quantum screening of Longitudinal Optical phonons is not as efficient as it would be in a strictly bidimensional system,indicating a remote coupling of confined states to polar phonons of the bulk.Furthermore,we show that a 3D Fröhlich interaction with Thomas-Fermi screening can be used to mimic the effects of such a remote coupling at the ɛ-InSe surface.In Chapter8,we study the layered 1T-TaS2.This material belongs to the Charge density waves (CDW) systems and has been extensively investigated by several research groups.In 1T-TaS2,the combination of structural distortion with high electronic correlations leads to a complex and fascinating phase diagram.We could reproduce controversial data that have been recently published in the literature and that identify a new instability in proximity of the metal to-insulator transition.Finally,chapter9 summarizes the conclusions of our work and briefly discusses the perspectives of some future directions of research

Повний текст джерелаMott insulators are a perfect example of how local electronic correlations can change macroscopic properties of materials. Varying slightly the doping or the pressure can transform a metal to an insulator. These properties can be modified extremely rapidly by driving these materials far from equilibrium. We have investigated the model Mott-Hubbard material Cr-doped V2O3 using state of the art pump-probe techniques, namely angle resolved photoelectron spectroscopy, optical reflectivity, THz time-domain spectroscopy, and X-ray diffraction. We were able to unequivocally disentangle the electronic and the lattice response of the system to a femtosecond laser excitation, which was kept in all cases at a wavelength of 800 nm. We present a comparative study of these transient responses, which demonstrates the strong electron-phonon coupling of this strongly correlated model material. We show that before thermalization, spectral weight is transferred from the lower Hubbard band towards the Mott gap. On a longer time scale a metastable state is stabilized by the lattice structure. To further understand the transient response of Mott insulators, we have also studied another Mott compound, BaCo1-xNixS2. The general trends of photoexcitation in Mott insulators are analyzed using a two orbital model. We argue that the filling of the gap can be due to a change of the specific orbital fillings

Повний текст джерелаFour dynamic membranes, Zr(IV) oxide, calcium oleate, poly-2-vinylpyridine and cadmium sulfide, were used to filter bovine serum albumin (BSA) in a disodium phosphate solution at pH = 8 and Prussian blue in distilled water. Prussian blue is a particle of 0.01(mu)m diameter with a zeta potential of -41mV while BSA is a macromolecule of 69,000 molecular weight, a Stokes-Einstein radius of 0.0038(mu)m and a zeta potential of -23.3mV at pH = 8. For BSA, the flux declined with time while the rejection increased. Filtrate fluxes increased with rotation rate and electric field and declined with concentration for both feeds. The flux declined beyond N = 2000rpm and was constant above C(,0) = 5.0wt%. For Prussian blue, the rejection was greater than 90% at all levels of E, N and C(,0). For BSA, the rejection increased with rotation rate and declined with concentration. The BSA rejection declined above N = 2000rpm and was constant beyond C(,0) = 0.5wt%.
A mathematical model was derived to predict the time variation of filtrate flux and a rejection model was used to predict the effect of surface concentration on BSA rejection.

Повний текст джерелаEsta Tesis está centrada en el estudio de Kepleratos, una familia de polioxometalatos con simetría icosaédrica. Los polioxometalatos son clusters inorgánicos anionicos compuestos por unidades MOn, donde M es un metal de transición normalmente en su estado de oxidación más alto (Mo(VI), W(VI), V(V)...). Por un lado, la estructura electrónica de los Kepleratos se ha estudiado desde un punto de vista de la Teoría del Funcional Densidad (DFT). Además, se ha analizado la interacción entre la cápsula Mo132 y sus correspondientes ligandos internos. Por otro lado, en colaboración con otros grupos, tanto experimental como teórico, se propone un mecanismo de formación de la cápsula Mo132 a partir de los datos obtenidos mediante espectroscopía Raman. Parte de la información obtenida mediante DFT se ha utilizado para obtener los parámetros necesarios para realizar una serie de simulaciones de Dinámica Molecular con el fin de estudiar el comportamiento del macro-ión Mo132 en solución acuosa en presencia de diferentes cationes (centrándose en la importancia de la hidrofobicidad del catión), así como los efectos de la temperatura en dicho comportamiento.
This Thesis is aimed at the study of a family of icosahedral symmetry polyoxometalates: the so-called Keplerates. Polyoxometalates are inorganic anionic clustters composed of MOn units, where M represents a transition metal atom usually at its highest state of oxidation Mo(VI), W(VI), V(V)...). On one hand, the electronic structure of Keplerates is studied from a Density Functional Theorey (DFT) point of view. Furthermore, the interaction between the Mo132 capsule and its inner ligands has been analyzed. On the other hand, in collaboration with both experimental and theoretical groups, a formation mechanism for the Mo132 capsule is proposed, based on Raman espectroscopy data. Part of the information achieved by DFT has been used to obtain the parameters required in order to perform Molcular Dynamics simulations regarding the behaviour of the Mo132 macro-ion in aqueous solution in the presence of different cations (focusing on the relevance of the hydrophobic character of teh cation), as well as the effects that temperature has on the system.

Повний текст джерелаRadial PDDs were measured for beta angles varying from 60º--120º of electron arc beams with energies of 6 MeV, 9 MeV, and 12 MeV and 2-D isodose distributions of electron arc beams were studied as well. Dose penumbral regions exist at the beam start area and stop area, and the size of these regions is a function of the beam energy and the field width. When shielded with a tertiary collimator, the size of the penumbral regions and the dose levels in the penumbral regions were reduced significantly, and it is sufficient for the shielding to cover exactly the start field and the stop field of the arc beam in a clinical setting.
The dose rate of the electron arc beam was investigated. It was found that the dose rate at the depth of dose maximum linearly increased with the arc beam field width and was independent of the arc angle.

Повний текст джерелаIn this thesis we explore in particular the dynamics of a special type of quasi-particle in pi-conjugated materials termed polaron, the origin of which is intimately related to the strong interactions between the electronic and the vibrational degrees of freedom within these systems. In order to conduct such studies with the particular focus of each appended paper, we simultaneously solve the time-dependent Schrödinger equation and the lattice equation of motion with a three-dimensional extension of the famous Su-Schrieffer-Heeger (SSH) model Hamiltonian. In particular, we demonstrate in Paper I the applicability of the method to model transport dynamics in molecular crystals in a region were neither band theory nor perturbative treatments such as the Holstein model and extended Marcus theory apply. In Paper II we expand the model Hamiltonian to treat the revolution of phenylene rings around the sigma-bonds and demonstrate the great impact of stochastic ring torsion on the intra-chain mobility in conjugated polymers using poly[phenylene vinylene] (PPV) as a model system. Finally, in Paper III we go beyond the original purpose of the methodology and utilize its great flexibility to study radiationless relaxations of hot excitons.

Повний текст джерелаI dagens samhälle är elektroniken ett allt viktigare och större inslag i vår vardag. Vi ser på TV, talar i mobiltelefoner, och arbetar på datorer. I hjärtat av denna teknologi finner vi diskreta komponenter och integrerade kretsar utformade främst för att styra strömmen av elektroner genom halvledande material. Traditionellt sett har kisel eller olika former av legeringar använts som det aktiva materialet i dessa komponenter och kretsar, men under de senaste 20 åren har såväl transistorer som solceller och lysdioder realiserats där det aktiva materialet är organiskt, d.v.s., kolbaserat.Vi befinner oss för tillfället mitt uppe i det kommersiella genombrottet för organisk elektronik. Redan idag säljs många MP3-spelare och mobiltelefoner med små skärmar där varje pixelelementen utgörs av organiska ljusemitterande dioder (OLEDs), men teknologin håller redan på att introduceras i mer storskaliga produkter som datorskärmar och TV-apparater som därigenom skulle kunna göras energieffektivare, tunnare, flexiblare och på sikt också billigare. Andra tekniska tillämpningsområden för organisk elektronik som förutspås en lysande framtid är RFID-märkning, organiska solceller, och elektronik tryckt på papper, men även smarta textiler och bioelektronik har stor utvecklingspotential.Den kanske största utmaningen kvarstår dock, att skapa elektroniska kretsar och komponenter uppbyggda kring enskilda molekyler, s.k. molekylär elektronik. Mycket snart närmar vi oss den fysikaliska gränsen för hur små komponenter som vi kan realisera med traditionella icke-organiska material som kisel och en stor drivkraft bakom forskningen på halvledande organiska material har varit just visionen om molekylär elektronik som inte är mer än några miljondelars milimeter stora. För detta ändamål krävs en mycket nogrann kontroll av tillverkningsprocesserna liksom en detaljförståelse för hur molekylerna leder ström och hur denna förmåga kan manipuleras för att realisera såväl traditionella som nya komponenter.I denna avhandling presenteras en översikt av den fysik som möjliggör ledningsförmåga hos särskilda klasser av organiska material, s.k. π-konjugerade system, samt de forskningsresultat som utgör mitt bidrag till denna disciplin. En av utmaningarna på området är den komplexitet som de organiska materialen erbjuder: laddningsprocesserna påverkas nämligen av en rad olika faktorer såsom laddningstäthet, temperatur, pålagd spänning, samt molekylernas former och inbördes struktur. I detta arbete har jag utifrån en vidareutveckling av existerande modeller genom numeriska datasimuleringar undersökt effekten av de senare tre faktorerna på elektronstrukturen, laddnigstransporten och energidissipation i denna klass av material.

Повний текст джерелаElectron quantum optics is a research field aiming at preparing, controlling and coherently manipulating single- to few-electrons states in mesoscopic systems, in the same way as single photons are manipulated in quantum optics. Single-electron sources are used to generate few-electron excitations in ballistic conductors, where their propagation is not affected by backscattering.Among several interesting problems related to electron quantum optics, an important question is whether and how interaction effects influence the evolution of single-electron excitations generated by coherent sources. This will be the main topic of this thesis.At first we consider a couple of co- or counter-propagating conduction channels coupled by repulsive electron-electron interactions. In both systems, interactions induce a fractionalization process causing the initially generated excitations to split into smaller ones, carrying only a fraction of the injected charge. These fractionalized excitations are studied both in the time domain as well as in energy and momentum space, which allows to access their particle-hole content. Moreover, specializing to the relevant case of excitations created by quantized Lorentzian voltage pulses, known as Levitons, we show that the noise generated when they are partitioned at a scatterer is minimal, regardless of interactions.Further on, a completely different kind of interaction is addressed, namely superconducting correlations. In particular, we investigate the transport properties of a superconducting tunnel junction under the effect of an arbitrary periodic drive, showing that Levitons do minimize the low frequency noise in this kind of device too
