description: The QCD axion solves the strong CP problem and represents an attractive particle candidate for cold dark matter (CDM). However, quantum fluctuations of the axion field during inflation easily result in large CDM isocurvature perturbations that are in conflict with observations of the cosmic microwave background (CMB). In this paper, we demonstrate how this problem can be solved in low-scale models of hybrid inflation that may emerge from supersymmetric grand unified theories. We consider both F-term hybrid inflation (FHI) and D-term hybrid inflation (DHI) in supergravity, explicitly taking into account the effect of hidden-sector supersymmetry breaking. We discuss the production of cosmic strings and show how the soft terms in the scalar potential readily allow to achieve the correct scalar spectral index. In both cases, we are able to identify large regions in parameter space that are consistent with all constraints. In particular, we find that evading the CDM isocurvature constraint always requires a small Yukawa or gauge coupling of O(10^-3) or smaller. This translates into upper bounds on the gravitino mass of O(10^5) GeV in FHI and O(10^9) GeV in DHI. Our results point to interesting scenarios in well-motivated parameter regions that will be tested in future axion and CMB experiments.

description: The intrinsic single particle momentum distributions in nuclei are supposed to show a universal behavior at large momenta, dominated by short-range correlated pairs, or quasi-deuterons. We discuss whether the quasi-deuteron universality survives the final state interaction effects, which are present in the missing momentum spectra measured in $A(e,e'p)$ experiments at GeV energies. We demonstrate that in the observed missing momentum spectra an approximate universality is present, but originating from the universal pattern of diffractive final state interactions of the struck proton independent of the target nucleus.

description: Background: Citrus bioflavonoids are polyphenolic compounds that are derived from citrus fruits and vegetables. Although they are well known for their powerful antioxidant properties, their effects on glycemic control are not well understood. This review aims to highlight the potential benefits of using citrus bioflavonoids in patients with type 2 diabetes mellitus and its metabolic complications, as well as the medicinal effects of known subclasses of naturally occurring citrus bioflavonoids. Methods: In this systematic review, a survey of studies was conducted from January 2012 to February 2023 using various databases (PubMed, Medline, Google Scholar, and Scopus) to determine the effects of citrus bioflavonoid supplementation on reducing oxidative stress, improving lipid profiles, and glycemic index in patients with diabetes mellitus, as well as the proposed mechanisms of action. Results: The results of the survey indicate that citrus bioflavonoids may have a positive impact on reducing oxidative stress levels in patients with type 2 diabetes mellitus. In addition to reducing oxidative stress, citrus bioflavonoids may also have a positive impact on other markers of diabetes. For example, studies have shown that they can reduce non-enzymatic protein glycation, which is a process that occurs when glucose molecules bind to proteins in the body. Conclusion: The reduction in oxidative stress that can be achieved using citrus bioflavonoids may help to maintain antioxidant levels in the body, thereby reducing the severity of diabetes and its complications. These findings suggest that citrus bioflavonoids may be a useful complementary therapy for patients with diabetes.

description: We compare the spectral properties of the millisecond and slow pulsars detected in the Parkes 70 cm survey. The mean spectral index for the millisecond pulsars (MSPs) is -1.9 +/- 0.1 whereas the mean spectral index for the slow pulsars is a surprisingly steep -1.72 +/- 0.04. A Kolmogorov-Smirnov test indicates that there is only a 72% probability that the two distributions differ. As a class, MSPs are therefore only fractionally steeper-spectrum objects than slow pulsars, as recent literature would suggest. We then model the expected distribution of millisecond pulsars in the Galaxy and find that high-frequency surveys, with sensitivities similar to the current Parkes multibeam survey, are likely to detect MSPs in large numbers. The observed distribution of MSPs will be much less isotropic than that resulting from low-frequency surveys, with 50% of detectable MSPs residing within 11 degrees of the Galactic plane in an all-sky survey.

Investigations into the ability of Piezoelectric Sensors to Monitor the Integrity of the Cemented Bond between Bone and Implant
Creators: name: Darton, Hannah
Publisher: name: Imperial College London
Year: 2015

description: This study investigates the utility of piezoelectric transduction to assess the structural health of a system through impedance analysis, with application to the field of ‘smart’ orthopaedic implants. The work is motivated by the high proportion of orthopaedic implant failures that occur due to loosening of the bond between the implant and the corresponding bone surface. The ultimate aim is to prove that piezoelectric sensors embedded within orthopaedic implants have the potential identify implant loosing before it would be shown in imaging techniques. Orthopaedic knee implants were selected as a case study for proof of concept for the proposed health monitoring system. Three distinct experiments were conducted: 1) Small piezoelectric sensors are attached to model tibial trays which are in turn attached with bone cement to sawbone blocks. The measured sensor impedance over a range of input frequencies is measured and analysis of the frequency impedance traces is carried out to determine what changes in the trace are indicative of the bone cement between the sawbone and aluminium curing; 2) Commercially available tibial trays cemented to sawbone tibias are progressively loosened under a fatigue load in a compressive testing rig. Results from three Linear Variable Differential Transducers (LVDTs) measuring the micromotion between the implant and sawbone are compared with frequencyMimpedance traces taken from a piezoelectric sensor attached to the top side of the tibial tray; and 3) Varying amounts of bone cement is used to cover the surface between a sawbone block and model tibial tray. Frequency-impedance readings are taken from a piezoelectric sensor adhered to the top side of the tray. Support vector machines are used to classify between the varying amounts of cement on each test sample. Experimental results and data analysis demonstrate the potential of piezoelectric sensors ability to provide information on the integrity of bone cement bond. Findings include: 1) Piezoelectric sensors can determine at what point bone cement bond between sawbone and an aluminium plate has cured; and 2) It is possible to identify different levels of cement coverage between sawbone and aluminium plate with an accuracy of up to 92 % with piezoelectric sensors. These findings establish the veracity of piezoelectric transduction as a means of identifying orthopaedic implant loosening in vivo. This investigation provides a firm basis for future work bringing the ideal of using piezoelectric sensors as a technique for detecting loose implants in vivo closer to becoming a reality.

description: Dispersion relations and amplitudes of collective pionic modes are derived in a pi + nucleon-hole + delta-hole model for use in transport descriptions by means of a local density approximation. It is discussed how pionic modes can be converted to real particles when penetrating the nuclear surface and how earlier treatments can be improved. When the surface is stationary only free pions emerge. The time-dependent situation is also addressed, as is the conversion of non-physical (i.e. unperturbed delta-hole) modes to real particles when the nuclear density vanishes. A simplified one-dimensional scenario is used to investigate the reflection and transmission of pionic modes at the nuclear surface. It is found that reflection of pionic modes is rather unlikely, but the process can be incorporated into transport descriptions by the use of approximate local transmission coefficients.

Investigating spatio-temporal dynamics of non-linear dispersive nano-plasmonics with advanced time-domain simulation methods
Creators: name: Renn-Giles, Fabian
Publisher: name: Imperial College London
Year: 2015

description: Over the last few decades, nano-fabrication techniques have evolved to such precision that novel optical material responses can be tailor-made to challenging specifications. This development has opened a new avenue to research areas such as nano-plasmonics and metamaterials, which investigate the behaviour of light on the nano-scale and promise a range of exciting new applications. A valuable tool for a better understanding of these systems are numerical simulations. However, the correct description of the phenomena in this new regime is however challenging as it inherently involves theories of multiple length and time scales, often including non-linear phenomena. This thesis discusses several simulation techniques and investigates their suitability for describing such systems. The focus lies on the Finite-Difference-Time-Domain technique (FDTD) - a method originally developed for the study of radio and microwave electro-magnetics. Unlike frequency-domain solvers, the FDTD method can naturally describe non-linear dynamics due to its time-domain nature. However, two main challenges must be overcome to extend the FDTD method to the nano-plasmonic regime: first, an accurate time-domain description of frequency-dependent, dispersive materials such as metals must be found and second - due to its lack of adaptive meshing - the FDTD method struggles to computationally efficiently calculate systems with features over a wide range of length scales. Both challenges are discussed in detail, along with suggestions on how to overcome them. In the second part of the thesis, the FDTD method is applied to the investigate the behaviour of a non-linear, nano-plasmonic dimer system - two infinitely long and nearly touching silver nanowires, coated with an active material (such as Rh800 dye). Although there have been many studies treating the purely plasmonic system - the silver nanowires - and the non-linear system - the dye coating - individually, describing the combined system with computer simulations has been challenging due to the reasons mentioned above. This system is therefore not only physically highly relevant but also offers a benchmark for the proposed numerical methods in this thesis.
A stochastic approach towards large eddy simulation of methanol/air spray flames
Creators: name: Noh, Dongwon
Publisher: name: Imperial College London
Year: 2015

description: The present work attempts to conduct numerical simulations of turbulent two-phase flows in two academic burners with methanol/air spray flames. It is challenging to simulate turbulent spray flames as many complex phenomena such as turbulence-chemistry interaction, spray dispersion and evaporation, and atomisation processes of liquid fuel occur simultaneously. The transported sub-grid scale (sgs) probability density function (pdf) equation in conjunction with the Eulerian stochastic field method formulated in the context of Large Eddy Simulation (LES) is applied to the experimental configurations operated with different fuel delivery systems, namely a commercial ultrasonic atomiser and a Research Simplex Atomiser (RSA). The performance of the LES methodology as an effective modelling tool for two-phase combusting flows is assessed by simulating a methanol/air turbulent nonpremixed spray flame with a fine droplet distribution achieved by the ultrasonic atomiser. Comparisons of the computed gas phase and droplet statistics with measurements show a good agreement, suggesting that the stochastic dispersion and evaporation models employed in this work are appropriate. The fundamental aspects of this turbulent spray flame such as the occurrence of external group combustion and its development into separate combusting islands are well reproduced. For this particular configuration, the significance of the sgs chemistry model in capturing the development of the flame is highlighted. A systematic, stochastic approach towards modelling a polydisperse droplet distribution associated with the simplex atomiser is developed in this study. The predictive capabilities of the stochastic breakup model are validated by detailed comparisons between the simulated results and the experimental data in terms of droplet and gas phase statistics. The general features of this spray flame including the lift-off height and the formation of a double reaction zone are reasonably well captured, confirming the validity of the LES-pdf formulation when applied to turbulent nonpremixed spray flames.
Multifunctional 45S5 Bioglass® - based composite scaffolds for bone tissue engineering
Creators: name: Newby, Phillipa Jane
Publisher: name: Imperial College London
Year: 2013

description: In the evolving field of bone tissue engineering, bioactive glass-ceramic scaffolds continue to draw significant attention as they can provide a 3D template that promotes new bone formation. These scaffolds have proved that they can loosely mimic cancellous bone structure as well as exhibiting appropriate mechanical properties and bioactivity to support the growth of new bone tissue. This work concentrates on improving the functionality of 45S5 Bioglass® -derived scaffolds produced by the foam replication technique, by introducing silver and copper through molten salt ion exchange to provide an antibacterial function and through the use of gelatin coatings to improve compressional strength, whilst not impeding the original scaffold’s bioactivity. The results confirmed that the introduced modifications have enhanced the scaffolds functionality as well as improving existing properties of the scaffolds such as mechanical competence. Overall the compressive strength of the scaffolds was improved with the addition of copper and silver ions and by the presence of gelatin coatings. After immersion in SBF, the presence of the additives did not impede the formation of hydroxyapatite on the scaffolds and hence the bioactivity. The characterization of the doped and coated samples showed that they have similar behavior to those of the base scaffold or have improved them marginally in terms of wettability and surface topography. During cell culture studies, using HPLSC’s, rMSC’s and hMSC’s, the silver doped scaffolds caused a slight cytotoxic effect, whilst the copper and silver/copper samples caused a significant cytotoxic effect. Bacterial studies showed that the metal ion-doped materials produced an antibacterial effect against the E.coli, S.aureus and K.pneumoniae. The present study has contributed to the enhancement of the standard 45S5 Bioglass® -derived scaffolds and has provided a base for future in vitro and in vivo work involving these materials in bone regeneration strategies.

description: We investigate the variations in galaxy occupancy of the dark matter haloes with the large-scale environment and halo formation time, using two state-of-the-art hydrodynamical cosmological simulations, EAGLE and Illustris. For both simulations, we use three galaxy samples with a fixed number density ranked by stellar mass. For these samples we find that low-mass haloes in the most dense environments are more likely to host a central galaxy than those in the least dense environments. When splitting the halo population by formation time, these relations are stronger. Hence, at a fixed low halo mass, early-formed haloes are more likely to host a central galaxy than late-formed haloes since they have had more time to assemble. The satellite occupation shows a reverse trend where early-formed haloes host fewer satellites due to having more time to merge with the central galaxy. We also analyse the stellar mass -- halo mass relation for central galaxies in terms of the large-scale environment and formation time of the haloes. We find that low mass haloes in the most dense environment host relatively more massive central galaxies. This trend is also found when splitting the halo population by age, with early-formed haloes hosting more massive galaxies. Our results are in agreement with previous findings from semi-analytical models, providing robust predictions for the occupancy variation signature in the halo occupation distribution of galaxy formation models.

$R_{K^{(*)}}$ and the origin of Yukawa couplings
Creators: name: King, Stephen F.
Publisher: name: arXiv
Year: 2018
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We explore the possibility that the semi-leptonic $B$ decay ratios $R_{K^{(*)}}$ which violate $μ- e$ universality are related to the origin of the fermion Yukawa couplings in the Standard Model. Some time ago, a vector-like fourth family (without a $Z'$) was used to generate fermion mass hierarchies and mixing patterns without introducing any family symmetry. Recently the idea of inducing flavourful $Z'$ couplings via mixing with a vector-like fourth family which carries gauged $U(1)'$ charges has been proposed as a simple way of producing controlled flavour universality violation while elegantly cancelling anomalies. We show that the fusion of these two ideas provides a nice connection between $R_{K^{(*)}}$ and the origin of Yukawa couplings in the quark sector. However the lepton sector requires some tuning of Yukawa couplings to obtain the desired coupling of $Z'$ to muons.

Ion beams accelerated by laser irradiation of thin foils and their applications
Creators: name: Hicks, George
Publisher: name: Imperial College London
Year: 2015

description: This thesis presents experimental measurements, supported by particle-in-cell simulations, of ion beams accelerated from ultra thin plastic foils by high intensity laser plasma interactions in the sheath acceleration and relativistic transparency regimes. An application of accelerated proton beams is radiography, which can be used to image the fields in high intensity laser plasma interactions. Experimental measurements are presented of observations of strong electromagnetic fields associated with plasma instabilities. The use of thin foils in high intensity laser experiments is attractive, because for thin foils the radiation pressure acceleration and relativistic transparency regimes begin to dominate. For intensities 1e20 W/cm^2, and target thicknesses <0.5 microns, laser heating causes the target to expand so that it becomes transparent to the laser. It has been postulated that targets that are transparent during the peak of the laser pulse, will experience increased electron heating and efficient proton acceleration. Optimum acceleration conditions were observed for target thicknesses, 100
Development of novel positron emission tomography pharmacodynamic markers for response assessment in cancer
Creators: name: Kenny, Laura
Publisher: name: Imperial College London

description: There is an urgent need to develop sensitive and specific biomarkers of response to treatment in oncology. This thesis explores the utility of three novel positron emission tomography (PET) radiotracers: [18F]-3'deoxy-3'fluorothymidine (FLT), [11C]choline and [18F]-AH111585. All patients in the PET studies had breast cancer. Aims: 1) To quantify the uptake and retention of [18F]FLT, [11C]choiine and [18F]-AH111585 in breast cancer, and evaluate the role of mathematical modelling compared to standard techniques for quantifying tracer uptake. 2) To correlate [18F]FLT and [11C]choiine PET data with immunohistochemical markers of proliferation. 3) To establish if [18F]FLT and [11C]choline PET are reproducible in breast cancer. 4) To determine the effect of anti-cancer treatment on [18F]FLT and [11C]choline PET. 5) To evaluate the diagnostic utility of [18F]-AH111585, a novel avps imaging agent, in breast cancer. Methods: 15 patients with primary and metastatic breast cancer were studied with [18F] FLT-PET at baseline, 2-7 days later, and then 7 days post-chemotherapy. [11C]Choline-PET was evaluated in 21 separate breast cancer patients, 13 for repeatability and 8 for response to trastuzumab. Finally, in 7 further patients [18F]-AH111585-PET was used to monitor angiogenesis in metastatic breast cancer. Findings: All tumour lesions had positive uptake of FLT, which correlated with cell proliferation, FLT uptake was found to have good repeatability,, and patients who clinically responded to chemotherapy also demonstrated significant early changes in FLT uptake. In the choline studies, all tumour lesions demonstrated significant uptake compared to normal tissue, and patients who clinically responded to trastuzumab also had a decrease in choline retention parameters. In seven patients studied with [18F]-AH111585-PET all but one lesion had significant retention of the tracer, suggesting that this agent may be promising for imaging angiogenesis.

The foreground discrete-source confusion was estimated from observations with higher resolution at the same frequency and in a scaled array at a lower frequency. Following the subtraction of the foreground confusion, the field shows no features in excess of the instrument noise. This limits the CMB anisotropy flat-band power to Q_flat < 23.6 microK with 95 per cent confidence; the ATCA filter function F_l in multipole l-space peaks at l_eff = 4700 and has half maximum values at l = 3350 and 6050.

description: We study scrambling in connection to multipartite entanglement dynamics in regular and chaotic long-range spin chains, characterized by a well defined semi-classical limit. For regular dynamics, scrambling and entanglement dynamics are found to be very different: up to the Ehrenfest time they rise side by side departing only afterwards. Entanglement saturates and becomes extensively multipartite, while scrambling continues its growth up to the recurrence time. Remarkably, the exponential behaviour of scrambling emerges not only in the chaotic case, but also in the regular one, when the dynamics occurs at a dynamical critical point.

description: The transverse momentum dependence of Hanbury-Brown/Twiss (HBT) interferometry radii for 2-body correlation functions provides experimental access to the collective dynamics in heavy-ion collisions. We present an analytical approximation scheme for these HBT radii which combines the recently derived model-independent expressions with an approximate determination of the saddle point of the emission function. The method is illustrated for a longitudinally boost-invariant hydrodynamical model of a heavy ion collision with freeze-out on a sharp hypersurface. The analytical approximation converges rapidly to the width of the numerically computed correlation function and reproduces correctly its exact transverse momentum dependence. However, higher order corrections within our approximation scheme are essential, and the previously published lowest order results with simple $m_{\perp}$ scaling behaviour are quantitatively and qualitatively unreliable.

description: The motion of electron wave packets in the Dirac semimetals A$_3$Bi (A=Na,K,Rb) is studied in a semiclassical approximation. Because of the two-fold degeneracy of the Dirac points and a momentum-dependent gap term in the low-energy Hamiltonian, the associated Berry curvature is non-Abelian. In the presence of background electromagnetic fields, such a Berry curvature leads to a splitting of trajectories for the wave packets that originate from different Dirac points and chiral sectors. The nature of the splitting strongly depends on the background fields as well as the initial chiral composition of the wave packets. In parallel electric and magnetic fields, while a well pronounced valley splitting is achieved for any chirality composition, the chirality separation takes place predominantly for the initially polarized states. On the other hand, in perpendicular electric and magnetic fields, there are clear deviations from the conventional Abelian trajectories, albeit without a well-pronounced valley splitting.

Black hole entropy from non-proper gauge degrees of freedom: II. The charged vacuum capacitor

description: The question which degrees of freedom are responsible for the classical part of the Gibbons-Hawking entropy is addressed. A physical toy model sharing the same properties from the viewpoint of the linearized theory is a charged vacuum capacitor. In Maxwell's theory, the gauge sector including ghosts is a topological field theory. When computing the grand canonical partition function with a chemical potential for electric charge in the indefinite metric Hilbert space of the BRST quantized theory, the classical contribution originates from the part of the gauge sector that is no longer trivial due to the boundary conditions required by the physical set-up. More concretely, in the benchmark problem of a planar charged vacuum capacitor, we identify the degrees of freedom that, in the quantum theory, give rise to an additional contribution to the standard black body result proportional to the area of the plates, and that allow for a microscopic derivation of the thermodynamics of the charged capacitor.

description: EMSO-Açores acquiert des séries de données temporelles multidisciplinaires en géophysique, océanographie,  géochimie, écologie et microbiologie (https://www.emso-fr.org/EMSO-Azores). L'acquisition de données haute fréquence grâce aux capteurs connectés et autonomes, couplée à un programme de suivi par échantillonnage et acquisition d'images durant les campagnes de maintenances, génèrent des séries temporelles à long terme de données pluridisciplinaires sur une large gamme d'échelles temporelles et spatiales, avec une résolution allant de quelques secondes à plusieurs décennies. Composante de l'EMSO (European Multidisciplinary Seafloor and water column Observatory) European Research Infrastructure Consortium (EMSO ERIC), qui coordonne 14 observatoires régionaux dans les mers européennes, c'est l'un des trois noeuds d'EMSO dans lequel les équipes françaises jouent actuellement un rôle moteur. La maintenance et le développement des infrastructures, ainsi que la gestion des données sont planifiés et approuvés au sein d'EMSO-France. La série des campagnes Momarsat vise à assurer la maintenance annuelle et l'évolution de l'infrastructure EMSO-Açores. Depuis 2010, la maintenance annuelle de cette infrastructure grand fond à l'aide de submersibles implique la récupération des instruments et des mouillages, un contrôle complet à bord, la maintenance, y compris la réparation, si nécessaire, de chaque composant et le redéploiement.@Damien ROUDEAU

description: It is not widely known how maize grain is stored in Ethiopia using hermetic storage methods. The purpose of the current study was, to evaluate the impact of different hermetic storage methods on storability of maize grain. The levels of storage methods were Metal silos, Purdue Improved Grain Storage bags, Super Grain Pro bags, plastic drums, and polypropylene bags as controls with 2, 4, and 6 months of storage. ANOVA was determined by factorial using SAS software. The experimental results showed that the storage methods had no significant (p<0.05) effect on fat, protein, and mold growth of stored maize. However, the storage methods had a significant effect (p<0.05) on the moisture content, number of live and dead insects, weight loss, bulk density, and germination test of maize grain. Among the storage method, Super grain bag and Purdue improvement crop storage bag had significantly higher values of germination test and bulk density when compared to the polypropylene bag and metal bin at different storage time. Finally, from this study it was concluded that hermetic storage methods such as Purdue improvement crop storage, Super grain bag, and Metal silo were important to preserve maize grain by lowering insect pest infestation and mold growth.

Searches for invisibly decaying Higgs bosons with the CMS detector
Creators: name: Dunne, Patrick James
Publisher: name: Imperial College London
Year: 2016

description: Searches for invisibly decaying Higgs bosons using the Compact Muon Solenoid (CMS) detector at the CERN Large Hadron Collider (LHC) and their interpretations are described. These searches are motivated both by a desire to characterise the newly observed Higgs boson, and by the cosmological observation of very weakly interacting matter in the universe, which is called dark matter. In order to provide context for these searches, introductions to the Standard Model (SM) of particle physics and several extensions to the SM which incorporate dark matter are given. The searches described in this thesis use data recorded in proton-proton collisions in 2012 and focus on the most sensitive mode, Vector Boson Fusion (VBF) production. The first search uses 19.5 fb 1 of data promptly reconstructed in 2012 and results in an observed (expected) limit on the invisible branching fraction of the 125 GeV Higgs boson, B (H -> inv), of 0.65 (0.49) at the 95% confidence level (CL) [1]. The second search uses 19.2 fb 1 of data collected using triggers with looser thresholds and reconstructed later, in 2013. This search resulted in an observed (expected) limit on B (H -> inv) of 0.57 (0.40) at the 95% CL [2]. Combinations of these searches with searches in other production channels are also described, the most sensitive of which results in an observed (expected) limit on B (H -> inv) of 0.36 (0.30) at 95% CL [3]. Projections of the sensitivity of these analyses in Run 2 and interpretations of their results as limits on various models of dark matter are also given [4].
Thieno[3,2-b]thiophene based conjugated polymers for high performance organic photovoltaic and field effect transistor applications
Creators: name: Meager, Iain
Publisher: name: Imperial College London
Year: 2014

description: The design, synthesis and characterisation of thirteen new semiconducting polymers for use in organic photovoltaic (OPV) and field effect transistor (OFET) devices are reported. The rational design of each polymer is discussed and their structures related to their varying chemical and physical properties, which are further used to rationalise the specific device performances. Various structural modifications are investigated with a focus on the electron-deficient bis-lactam structures diketopyrrolopyrrole (DPP) and isoindigo, that are flanked by thieno[3,2-b]thiophene donor groups. Alkyl chain optimisation of thieno[3,2-b]thiophene diketopyrrolopyrrole (DPPTT) based co-polymers was thoroughly examined and it was found that increased alkyl chain size affords improved solubility and a wider range of accessible co-monomer units. Exploiting this improved solubility, the new DPPTT-T polymer was fractionated using recycling gel permeation chromatography (GPC). This gave fractions with increased molecular weights and narrowed mass distributions resulting in OPV power conversion efficiency (PCE) ehancements of greater than 50 %. Continuing with DPPTT-T alkyl chains, a new OPV structural design consideration is introduced in which the alkyl chain branching position is systematically moved further from the polymer backbone. This resulted in higher molecular weight polymers with stronger π - π interactions and significantly enhanced device performances due to increased intermolecular interactions, with PCEs in excess of 8 %. Using the new higher performing branched alkyl chains the role of differing chalcogenophene co-monomers OPV devices was also investigated and was found that increased heteroatomic size, from thiophene to selenophene to tellurophene, resulted in narrowed optical band gaps and increased heteroatom – heteroatom interchain interactions. When these differences are taken into consideration, thiophene is shown to be the highest performing chalcogenophene comonomer of the series. Moving to isoindigo, a new thieno[3,2-b]thiophene flanked structure (iITT) was designed and synthesised for the first time. The resultant narrow band gap co-polymers were shown to be excellent candidate materials for ambipolar OFET applications. Through a comparative literature and computational study, the new iITT unit is shown to be one of the highest performing units within this family of polymer structures.
