Mechanisms and kinetics of electron injection in dye-sensitized solar cells
Creators: name: Juozapavicius, Mindaugas
Publisher: name: Imperial College London
Year: 2015

description: Electron injection in dye-sensitized solar cells (DSSC) has been extensively studied in the present thesis. Many transient and steady-state experimental techniques were utilized: ultrafast transient absorption spectroscopy in the visible, near-IR and mid-IR regions; time-correlated single photon counting; incident photon to current conversion measurement; temperature dependence of luminescence and device efficiency; determination of energy conversion efficiency parameters. All these methods were collated and analysed as a whole, providing a very detailed picture of the electron injection. It was found that in devices utilizing the most efficient Ru-bipyridyl dyes and commercially viable, performance optimized iodine/triiodide electrolytes, electron injection kinetics are multiphasic, with significant components in the femtosecond, tens of picoseconds and in nanosecond regimes. The broad non-exponential kinetics gave rise to non-100% efficient injection. A fraction of the dyes manage to decay giving rise to luminescence. All of these observations were fully quantified and validated by performing measurements on different systems. The huge length of the delay lines in TAS measurements and very broad probe wavelengths used in the current work gave a very detailed picture of the injection process. Along the way, some very basic experiments were done, which added confidence to the results obtained in the thesis. In addition, interesting phenomena occurring in the ultrafast timescales were found and spectra of transient species such as the dye excited states were recorded. Finally, relevance of the current work to the practical aspects of the solar cells was described and future work discussed.

description: We created Staphopia, an analysis pipeline, database and Application Programming Interface for batch analysis of thousands of S. aureus Illumina whole genome shotgun projects. Written in Python, Staphopia’s analysis pipeline consists of submodules running open-source tools. It accepts raw FASTQ reads as an input, which undergo quality control filtration, error correction and reduction to a maximum of approximately 100x chromosome coverage. This reduction significantly reduces total runtime without detrimentally affecting the results. The pipeline performs de novo assembly-based and mapping-based analysis. Automated gene calling and annotation is performed on the assembled contigs. Read-mapping is used to call variants (single nucleotide polymorphisms and insertion/deletions) against a reference S. aureus chromosome (N315, ST5). We ran the analysis pipeline on more than 43,000 S. aureus shotgun Illumina genome projects in the public European Nucleotide Archive database in November 2017. We found that only a quarter of known multi-locus sequence types (STs) were represented but the top ten STs made up 70% of all genomes. Methicillin-resistant S. aureus (MRSA) were 64% of all genomes. Using the Staphopia database we selected 380 high quality genomes deposited with good metadata, each from a different multi-locus sequence type, as a non-redundant diversity set for studying S. aureus evolution. In addition to answering basic science questions, Staphopia could serve as a potential platform for rapid clinical diagnostics of S. aureus isolates in the future. The system could also be adapted as a template for other organism-specific databases.
Follow up of the CFRS with HST, ISO and VLA: the cosmic star formation rate as derived from the FIR luminosity density

description: Properties of CFRS field galaxies up to z=1 are discussed. Estimations of the cosmic star formation rate (SFR) lead to serious problems if they not account for AGN emissions and for light reemitted at IR wavelengths. Deep ISOCAM and VLA photometries on one CFRS field have been performed. Multi-wavelength analyses from UV to Mid-IR and hence to radio allow us to classify sources from their spectral energy distributions. This provides an estimation of the FIR luminosity density related to star formation. The deduced SFR density is free of extinction effects and not contaminated by AGN emissions. About 55+/-20% of the star formation at z<=1 is related to FIR emission. If a non truncated Salpeter IMF is adopted, the derived stellar mass formed from z=0 to z=1 seems too high when compared to the present day stellar mass. An important fraction (30%) of the star formation at z=0.5-1 seems to be related to the rapidly evolving population of compact/Irr galaxies. Larger systems found at z=1, show a slower evolution of their star formation properties.

COMPARISON OF N-BODY SIMULATIONS TO STATISTICAL OBSERVATIONS OF GALAXY PAIRS

description: N-body simulations were conducted of pairs of galaxies with a 3:1 mass ratio on parabolic orbits, in order to quantify the effect of dynamical friction. The effects of varying the ratio of the dark matter halo size to the distance of closest approach were explored. Once the dark matter halos are fully overlapping, the more massive simulated galaxies achieve a larger maximum separation after the first encounter despite the increased dynamical friction caused by the more extended halos. Projected separation and radial velocity histograms were generated by "observing" the simulation results at various times and from various orientations. These histograms were compared with observations of galaxy pairs (Charlton & Salpeter 1991; Chengalur, Salpeter, & Terzian 1993) with the result that large halo radii (~200 - 600 kpc) and wide distances of closest approach are generally favored. It is difficult to reconcile the small radial velocity differences that have been observed (median of ~ 30 km/s, Chengalur et al. 1993) with the simulations when we sample all parts of the orbits equally. Including an additional population of wide pairs that have just recently reached "turnabout" from the Hubble flow would lower the median velocity differences. Models suggest that additional data for pairs at intermediate separations should have a somewhat larger median velocity difference than the wide pairs. Very narrow pairs include galaxies which are interacting, and whose gaseous components respond to forces other than gravity. If consistently small $Δv$ are measured from neutral hydrogen velocities in a larger sample of narrow pairs, pressure forces and dissipation effects on the gaseous components could be responsible.

Supernova pencil beam survey
Creators: name: Wang, Yun
Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Type Ia supernovae (SNe Ia) can be calibrated to be good standard candles at cosmological distances. We propose a supernova pencil beam survey that could yield between dozens to hundreds of SNe Ia in redshift bins of 0.1 up to $z=1.5$, which would compliment space based SN searches, and enable the proper consideration of the systematic uncertainties of SNe Ia as standard candles, in particular, luminosity evolution and gravitational lensing. We simulate SNe Ia luminosities by adding weak lensing noise (using empirical fitting formulae) and scatter in SN Ia absolute magnitudes to standard candles placed at random redshifts. We show that flux-averaging is powerful in reducing the combined noise due to gravitational lensing and scatter in SN Ia absolute magnitudes. The SN number count is not sensitive to matter distribution in the universe; it can be used to test models of cosmology or to measure the SN rate. The SN pencil beam survey can yield a wealth of data which should enable accurate determination of the cosmological parameters and the SN rate, and provide valuable information on the formation and evolution of galaxies. The SN pencil beam survey can be accomplished on a dedicated 4 meter telescope with a square degree field of view. This telescope can be used to conduct other important observational projects compatible with the SN pencil beam survey, such as QSOs, Kuiper belt objects, and in particular, weak lensing measurements of field galaxies, and the search for gamma-ray burst afterglows.

Dark matter for $b\to s μ^+ μ^-$ anomaly in a gauged $U(1)_X$ model

Year: 2018
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We propose a new physics model which has a cold dark matter candidate and can explain the $b \to s μ^+μ^-$ anomaly at the same time. Our model includes a scalar quark $\widetilde{q}$ and a scalar lepton $\widetilde{\ell}$ which are $SU(2)_L$-doublet as well as a Dirac fermion $N$ which is $SU(2)_L$-singlet. The new particles are charged under a gauged $U(1)_X$ group which is spontaneously broken to a discrete $Z_2$ symmetry by a dark scalar $S$. The remnant $Z_2$ symmetry stabilizes the dark matter. Box diagrams with $\widetilde{q}$, $\widetilde{\ell}$, and $N$ running inside the loop can generate the correct Wilson coefficients $C_9^μ= -C_{10}^μ$ to accommodate the $b \to s μ^+μ^-$ anomaly while avoiding constraints such as $B_s-\overline{B}_s$ mixing. The dark matter annihilation into a second generation lepton pair via $t$-channel $\widetilde{\ell}$-exchanging process plays an important role in producing the current dark matter relic abundance of the universe, showing a strong interplay between the flavor and dark matter physics. We also discuss dark-gauge-interaction-dominated and Higgs-portal-dominated scenarios for dark matter physics.

Weak Lensing by Large Scale Structure in Open, Flat, and Closed Universes

description: Weak lensing is the distortion (polarization) of images of distant objects, such as high redshift galaxies, by gravitational fields in the limit where the distortion is small. Gravitational potential fluctuations due to large scale structure cause correlated distortions of the images of high redshift galaxies. These distortions are observable with current large telescopes and instrumentation. In a Friedmann-Robertson-Walker (FRW) metric I calculate the weak lensing pattern due to large scale structure for arbitrary $Ω_0$ and zero cosmological constant $Λ$. For a given cosmological model, specified by $Ω_0$ and a power spectrum of density fluctuations, I calculate the statistical properties of the polarization field for an arbitrary redshift source distribution in a simple closed form. It is shown that for low redshift $z$ of the sources, the polarization amplitude is proportional to $Ω_0$, while at higher redshift the polarization measures the value of $Ω(z)$, where $z$ is the characteristic source redshift. Moreover, the statistics of the polarization field are a direct measure of the power spectrum of density fluctuations.

Control and operation of centrifugal gas compressors, with an emphasis on CO2 compression
Creators: name: Budinis, Sara
Publisher: name: Imperial College London
Year: 2015

description: The PhD project focuses on operation and control of centrifugal gas compressors for carbon dioxide application. The analysis of the industrial background and the review of the academic literature have highlighted some research needs consisting in: - Improvement of the performance of the pressure controller of the compressor - Integration of pressure and surge control - Analysis of the effect of the recycle configuration on the operation of the compressor. Control configurations have been proposed in order to: - Reduce the interaction between control loops - Guarantee the stable and safe operation of the control system - Deal with partial and full recycle operation in supercritical carbon dioxide applications. Dynamic modelling and simulations have been employed in order to analyse the effect of boundary disturbances on the operation of the open and closed loop compression system. The performance of the system has been evaluated by means of graphical representation of controlled and manipulated variables and also by means of proposed performance indicators. These indicators focus on specific aspects of the operation of a compressor such as control performance, power consumption and amount of gas recycled. The results of the thesis demonstrate that better pressure control reduces the risk of surge. Moreover the interaction between pressure controller and surge controller can be avoided by employing a linear model predictive controller. The controller has been tuned according to various control purposes such as energy saving, surge avoidance or pressure control performance. The results also demonstrate that the recycle configuration influences surge occurrence, control stability and power consumption of the compression station. This phenomenon is emphasised when dealing with supercritical carbon dioxide because of the high density of the fluid.

description: In order to obtain the equation of state and construct hybrid stars, we calculate the thermodynamic potential in the two-flavor Nambu--Jona-Lasinio model with tensor-type four-point interaction between quarks. In addition, we impose the beta equilibrium and charge neutrality conditions on the system. We show that the tensor condensate appears at large chemical potential, however, it is difficult to hold hybrid stars with two-solar mass by using the equation of state with the tensor interaction. Although we cannot obtain the stars with two-solar mass because of the absense of the repulsive interaction, the estimated magnetic moment density is very large. Therefore, we expect that the tensor interaction descrobes the magnetic fields of compact stars.

Testing the Relation Between the Local and Cosmic Star Formation Histories

Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Recently, there has been great progress toward observationally determining the mean star formation history of the universe. When accurately known, the cosmic star formation rate could provide much information about Galactic evolution, if the Milky Way's star formation rate is representative of the average cosmic star formation history. A simple hypothesis is that our local star formation rate is proportional to the cosmic mean. In addition, to specify a star formation history, one must also adopt an initial mass function (IMF); typically it is assumed that the IMF is a smooth function which is constant in time. We show how to test directly the compatibility of all these assumptions, by making use of the local (solar neighborhood) star formation record encoded in the present-day stellar mass function. Present data suggests that at least one of the following is false: (1) the local IMF is constant in time; (2) the local IMF is a smooth (unimodal) function; and/or (3) star formation in the Galactic disk was representative of the cosmic mean. We briefly discuss how to determine which of these assumptions fail, and improvements in observations which will sharpen this test.

Molybdenum and platinum isotope anomalies in iron meteorites – constraints on solar nebula heterogeneities and parent body processes
Creators: name: Poole, Graeme
Publisher: name: Imperial College London
Year: 2015

description: Recent investigations revealed systematic nucleosynthetic Mo isotope anomalies in meteorites, affording clear evidence for variable excesses in p- and r process nuclides, and hence deficits in s process nuclides. These anomalies were interpreted as reflecting selective destruction/removal of unstable presolar components, within the framework of thermal processing models that also take into account data for other elements (e.g., Ru, Zr, Os). To test such models, this study has undertaken extensive measurements of Mo and Pt isotopes in iron meteorites, providing the most precise data for the broadest range of samples analysed to date. The data presented here are in agreement with previous studies, with all groups analysed (except the IAB/IIICD complex) displaying deficits in s process Mo nuclides, with the extent varying between groups. This unique dataset allows, for the first time, resolution of decoupled p process and r process isotope effects, providing the basis for an updated thermal processing model. Mass-independent Pt isotope anomalies were also observed, but these are interpreted as entirely cosmogenic in origin, resulting from exposure of the meteoroids to galactic cosmic rays. No nucleosynthetic Pt isotope anomalies are resolvable, in accord with predictions from the updated thermal processing model. Systematic variations in the stable isotope compositions of Mo (δ98Mo) and Pt (δ198Pt) within iron meteorite groups were found, reflecting internal processes within the parent bodies. In detail, these result from isotope fractionation during metal–sulphide partitioning of Mo, and solid–liquid metal partitioning of Pt, respectively. Significantly, a previously undetected correlation between the magnitude of the nucleosynthetic Mo isotope anomalies and δ98Mo values of iron meteorite parent bodies provides novel support for the thermal processing model. However, no signatures of elemental processing in the solar nebula are resolvable in δ198Pt, as any such effects were overprinted by the isotopic fractionation that accompanied partitioning of Pt between solid and liquid metal.

description: We re-examine the thermal evolution of the postshock layer in primordial gas clouds. Comparing the time scales, we find that the evolutionary paths of postshock regions in primordial gas clouds can be basically understood in terms of the diagram drawn in the ionization degree vs temperature plane. The results obtained from the diagram are independent of the density in the case that we do not include photodissociation and photoionization. We also argue that the diagram is not only relevant to the case of the steady postshock flow, but also to the isochorically cooling gas.

Heel biomechanics under blast conditions
Creators: name: Grigoriadis, Grigorios
Publisher: name: Imperial College London
Year: 2016

description: The deformation of the floor above a vehicle attacked by an improvised explosive device transmits a high-rate, primarily axial, load to the lower limb of the occupants resulting in intra-articular, difficult-to-treat fractures of the foot and ankle. The aim of this thesis was to improve understanding of the biomechanics of the foot and ankle during this incident as a first step towards better design of efficient mitigation strategies. Due to the great potential of computational methods, the aim was achieved by developing and using a finite element model. A great challenge in developing FE models of biological systems regards the selection of appropriate material properties for biological tissues. The material properties of the heel fat pad are critical for the response of an FE model of the foot and ankle and yet ill-understood for high loading rates. The first objective of this thesis was to characterise the material behaviour of the heel fat pad across strain rates. This was achieved by importing data from tests performed on cadaveric heels to an inverse FE optimisation algorithm that was developed and used to quantify the non-linearly viscoelastic material properties of the tissue. An FE model of the foot and ankle was developed in this study to simulate high rate axial loading based on scans of a cadaveric specimen. The biofidelity of the response of the model was assessed against experimental data from various non-catastrophic tests; the good agreement between experimental and computational results allowed for a thorough analysis of the kinetic and kinematic response of all tissues which have allowed for a better understanding of the biomechanics of the foot and ankle in underbody blast. These findings offer an insight into the incident and can be used to facilitate the design of protective equipment and develop new ideas for mitigation strategies.

description: We report the codiscovery of the spatially-resolved dust disk of the Vega-like star HR 4796A. Images of the thermal dust emission at $λ= 18 μ$m show an elongated structure approximately 200 AU in diameter surrounding the central A0V star. The position angle of the disk, $30^{\circ} \pm 10^{\circ}$, is consistent to the position angle of the M companion star, $225^{\circ}$, suggesting that the disk-binary system is being seen nearly along its orbital plane. The surface brightness distribution of the disk is consistent with the presence of an inner disk hole of approximately 50 AU radius, as was originally suggested by Jura et al. on the basis of the infrared spectrum. HR 4796 is a unique system among the Vega-like or $β$ Pictoris stars in that the M star companion (a weak-emission T Tauri star) shows that the system is relatively young, $\sim 8 \pm 3$ Myr. The inner disk hole may provide evidence for coagulation of dust into larger bodies on a timescale similar to that suggested for planet formation in the solar system.

description: In this paper we review the hypothesis that a considerable part of the cosmic ray flux observed above about $10^{19}\eV$ may be produced by decaying or annihilating topological defects left over from phase transitions in the early universe at grand unification energy scales ($\approx10^{16}\GeV$). Possible signatures of cosmic ray producing defect models are discussed which could be tested experimentally in the near future. We thereby focus on model independent universal spectral properties of the predicted particle fluxes.

Reheating constraints on Tachyon Inflation

description: Tachyon inflation is one of the most attractive models of noncannonical inflation motivated by string theory. In this work we revisit the constraints on tachyon inflation with inverse $\cosh$ potential and exponential potential considering reheating, Although the phase of reheating is not well understood, it can be parameterized in terms of reheating temperature $T_{re}$, number of e-folds during reheating $N_{re}$ and effective equation of state during reheating $w_{re}$, which can be related to the parameters of the tachyon potential, spectral index $n_s$ and tensor-to-scalar ratio $r$. For various reheating scenarios there is a finite range of $w_{re}$ and the reheating temperature should be above electroweak scale. By imposing these conditions, we find that both the inverse $\cosh$ potential and exponential potential are disfavored by Planck observations. We also find that $w_{re}$ for both these potentials should be close to $1$ to satisfy Planck-2015 joint constraints on $n_s$ and $r$.

description: We present a new method to estimate shear measurement bias in image simulations that significantly improves the precision with respect to current techniques. Our method is based on measuring the shear response for individual images. We generated sheared versions of the same image to measure how the galaxy shape changes with the small applied shear. This shear response is the multiplicative shear bias for each image. In addition, we also measured the individual additive bias. Using the same noise realizations for each sheared version allows us to compute the shear response at very high precision. The estimated shear bias of a sample of galaxies is then the average of the individual measurements. The precision of this method leads to an improvement with respect to previous methods concerned with the precision of estimates of multiplicative bias since our method is not affected by noise from shape measurements, which until now has been the dominant uncertainty. As a consequence, the method does not require shape-noise suppression for a precise estimation of shear multiplicative bias. Our method can be readily used for numerous applications such as shear measurement validation and calibration, reducing the number of necessary simulated images by a few orders of magnitude to achieve the same precision.

Gaussian Quantum Trajectories for the Variational Simulation of Open Quantum-Optical Systems

description: We construct a class of variational methods for the study of open quantum systems based on Gaussian ansatzes for the quantum trajectory formalism. Gaussianity in the conjugate position and momentum quadratures is distinguished from Gaussianity in density and phase. We apply these methods to a driven-dissipative Kerr cavity where we study dephasing and the stationary states throughout the bistability regime. Computational cost proves to be similar to the truncated Wigner (TWA) method, with at most quadratic scaling in system size. Meanwhile, strong correspondence with the numerically exact trajectory description is maintained so that these methods contain more information on the ensemble constitution than TWA and can be more robust.
