Synthesis and characterisation of sequence-controlled multifunctional multiblock polyesters via quantitative one-pot iterative living ring-opening polymerisation (QOIL-ROP)
Creators: name: Yu, Li
Publisher: name: Imperial College London
Year: 2020

description: Scientists have devoted enormous efforts towards developing various synthetic strategies for translating the defined sequences and specific functions of natural biomacromolecules to the synthetic polymers. However, the majority of sequence-controlled polymers fabricated through existing synthetic strategies are commonly non-biodegradable and chain-transfer agents and the halides (used in metal-mediated approaches) are generally attached to the polymer backbone in many current liquid-phase iterative strategies even after isolation, which restrict their potential applications across a wide range of scientific and technological fields. Moreover, some existing synthetic strategies rely on thorough purifications in each cycle. Herein, this thesis presents the work on a novel and simple strategy for scalable production of well-defined sequence-controlled multifunctional multiblock polyesters composing biocompatible and biodegradable backbones with site-selective functionality via the new quantitative one-pot iterative living ring-opening polymerisation (QOIL-ROP) method. This new approach enables the synthesis of highly ordered multiblock copolyesters without any intermediate purification, allowing not only well-defined molecular weight but also nearly perfect unprecedented control of the microstructure in terms of the arbitrary distribution and chain length of each building block along the chain. To demonstrate the versatility of this approach, seven proof-of-concept polyesters were synthesised, including model quasi muliblock polyesters (A6A6A6A6A6 and A4A6A4A6A4) and multiblock copolyesters (A6B6A6B6A6, A4B6A4B6A4, A6B6A6A6B6, A6A6A6B6B6 and A6(B4C2)A6(B4C2)A6) with near-quantitative monomer conversions and relatively narrow molecular weight distributions for such complex structures in each cycle during the iterative polymerisation chain extension process. The sequence-controlled pentablock A6B6A6A6B6 copolyester was chosen to demonstrate scale-up synthesis on a multigram scale (∼56 g), further highlighting the robustness and commercialisation potential of the new strategy. This approach offers new perspectives for the design and synthesis of a new generation of artificial highly organised multifunctional macromolecular platform. Moreover, through this robust approach, prominently tunable physicochemical and biodegradable properties as well as structural and site-selective functional complexities were successfully built into the water-soluble, multifunctional, sequence-controlled polyesters by precisely controlling the chain composition, monomer sequence and chain length. This would unlock promising diverse, real-world applications from healthcare to nanotechnology and information storage.

Palladium-catalysed directed C(sp3)–H functionalisation of saturated N-heterocycles at unactivated C4 positions
Creators: name: Antermite, Daniele
Publisher: name: Imperial College London
Year: 2020

description: Saturated N-heterocycles are prevalent motifs in bioactive compounds and represent important structures for pharmaceutical screening. As such, synthetic methods that can readily access these derivatives with high regio- and stereocontrol would be of significant value for the discovery of new therapeutics. Catalytic C–H functionalisation offers high potential for the iterative and divergent synthesis of substituted N-heterocycles from simple cyclic precursors. The research in this thesis describes the selective synthesis of cis-3,4-disubstituted pyrrolidines and piperidines by Pd-catalysed C(sp3)–H functionalisation with aryl iodides. As described in chapter 3, high regio- and stereoselectivity is achieved using an aminoquinoline amide directing group at C(3), with C(4)-functionalisation always preferred over competing C(2). Divergent directing group removal delivers various biologically relevant building blocks, containing amide, carboxylic acid and alcohol functionalities. The synthetic utility of this protocol for drug discovery applications is described in chapter 4. C(4)–H arylation followed by directing group removal enables the stereocontrolled formal synthesis of antidepressant (–)-paroxetine and the total synthesis of enantiopure Br- and I-paroxetine analogues. Furthermore, the synthesis of a library of arylated pyrrolidine and piperidine fragments for pharmaceutical screening is demonstrated. Mechanistic investigations into the observed regio- and stereoselectivity are discussed in chapter 5. Deuteration studies, kinetic analysis and DFT calculations suggest reversible C–H activation to occur at different positions on the ring. Subsequent stereodetermining oxidative addition of PdII to PdIV and turnover-limiting reductive elimination deliver the C(4)-arylated products as cis-diastereomers. During this study, evidence for a fast catalyst deactivation process is observed. Attempts to overcome this limitation are finally discussed in chapter 6. This ultimately results in the development of an improved 4-dimethylamino-8-quinolinyl amide directing group. This novel removable auxiliary provides a faster reaction rate, higher yields and a broader substrate scope, and enables the late-stage functionalisation of complex biorelevant compounds.

description: Obtaining eigenvalues of permutations acting on the product space of $N$ representations of SU($n$) usually involves either diagonalising their representation matrices on total-weight subspaces or decomposing their characters, which can be obtained from Frobenius' formula or via graphical methods using Young tableaux. For products of fundamental representations of SU($n$), Schuricht and one of us proposed the method of extended Young Tableaux, which allows reading the eigenvalues of the cyclic permutation $C_N$ directly off the, slightly modified, standard Young tableaux labelling an irreducible SU($n$) representation. Here we generalise the method to all symmetric representations of SU($n$), and show that $C_N$ eigenvalue computation based on extended Young tableaux is at least linearly faster than the standard methods mentioned.

Paper-based printed electrical gas sensors and their application in food freshness and human breath monitoring
Creators: name: Barandun, Giandrin
Publisher: name: Imperial College London
Year: 2020

description: This thesis introduces an entirely new class of printed electrical gas sensors that are produced at near ‘zero cost’. This technology exploits the intrinsic hygroscopic properties of cellulose fibres within paper; although it feels and looks dry, paper contains substantial amount of moisture, absorbed from the environment, enabling the use of wet chemical methods for sensing without manually adding water to the substrate. The sensors exhibit high sensitivity to water-soluble gases with a fast and reversible response. The sensors show comparable or better performance (especially at high relative humidity) than most commercial ammonia sensors at a fraction of their price (<$0.02 per sensor for the cost of materials for laboratory prototypes). This thesis demonstrates that the sensors proposed can be integrated into food packaging to monitor freshness of protein-rich food. Tests on poultry and cod fish fillet show that the sensors detect an increase in decomposition gases (mainly trimethylamine and ammonia) which correlates to the findings of microbial control experiments. The sensors are implemented into near-field-communication tags to function as wireless, battery-less gas sensors that can be interrogated with smartphones. In a next step this thesis demonstrates functionalized versions of the paper-based gas sensors where the pH of the paper is changed by adding sulfuric acid or sodium hydroxide. In the presence of alkaline or acidic gases the neutralization effect in the sensors decouple fluctuations in relative humidity from gas concentration changes. An array of sensors with different pH can distinguish between alkaline and acidic gases. The functionalized sensors quantitatively detect ammonia in a respiratory simulator where relative humidity varies widely with inhalation and exhalation. In healthy human subjects the sensors detect ammonia when a subject eats salty liquorice (an ammonium chloride containing candy) while breathing normally. This can be used to detect increased ammonia levels in human breath which can indicate a variety of renal and hepatic diseases.

description: Στην παρούσα διπλωματική εργασία εξετάζεται η χειραγώγηση της κοινής γνώμης ως ένα καίριο πρόβλημα που αντιμετωπίζει η σημερινή κοινωνία. Ως χειραγώγηση θεωρείται οποιαδήποτε άσκηση επίμονης και σοβαρής πίεσης, κυρίως ψυχολογικής, επάνω σε έναν άνθρωπο με σκοπό να τον οδηγήσει, παρά τη θέλησή του, σε μία πράξη ή μια παράλειψη που θα του είναι βλαπτική. Ένας από τους σημαντικότερους πρωταγωνιστές αυτής της διαιώνισης του συγκεκριμένου προβλήματος είναι τα μέσα ενημέρωσης και, ιδιαιτέρως, τα μέσα κοινωνικής δικτύωσης.Πιο συγκεκριμένα, γίνεται παρουσίαση του Twitterκαι των τρόπων με τους οποίους η συγκεκριμένη πλατφόρμα δημιουργεί εύφορο έδαφος για να αναπτυχθεί το προαναφερθέν πρόβλημα, με τη γέννηση και διασπορά ψευδών ειδήσεων (fakenews).
Επίσης, στην παρούσα διπλωματική εργασία παρουσιάζεται ο ρόλος των δεδομένων μεγάλης κλίμακας (BigData) και οι τεχνικές με τις οποίες η άντλησή τους συναρτάται με τη χειραγώγηση της κοινής γνώμης επάνω σε ένα ζήτημα. Επιπλέον, επισημαίνεται η μεγάλη σημασία της κατηγοριοποίησης και ταξινόμησης δεδομένων μεγάλης κλίμακας με τη βοήθεια αλγορίθμων εποπτευόμενης μηχανικής μάθησης. Και, τέλος, δίνεται έμφαση στη διαδικασία της ανάλυσης, επεξεργασίας και τελικά ταξινόμησης ενός κειμένου φυσικής γλώσσας, όπως για παράδειγμα ένα tweet με βάση το συναισθηματικό φορτίο του γράφοντος.

description: The present dissertation focuses on the manipulation of public opinion as a key problem faced by today's society. The term manipulation encapsulates, any deceptive or indirect tactic including persistent and serious pressure, especially psychological, intended to influence and change the behavior or perception of others. One of the most important factors of the perpetuationof public opinion manipulatingis the role of the media and, in particular,social media. More specifically,Twitter and the ways in which this platform creates a fertile ground to develop the aforementioned problem, with the birth and spreading of fake news are herein presented.
In this framework, the role of Big Data and the techniques that mediate the manipulation of public opinion on an issue are presented. In addition, the importance of classifying large-scale data (Big Data) with the help of supervised machine learning algorithms,is highlighted. Finally, the center of interest focuses on the process of analyzing, processing andclassifying a natural language text, such as a tweet based on the writer's emotional load.

description: The emergence of the computer and the rapid development of technology have led to the organization of communications networks and the creation of applications that support various human activities based on computer networks. The networks were initially isolated and consistently provided the required protection against malicious users. Nevertheless, the development of information technology, coupled with the need to put all these services at the citizen's convenience, in order to facilitate their daily routine at all levels, has made them widely accessible, while at the same time increasing their vulnerability.
The purpose of this paper is to present the forms of conflict taking place in cyberspace, with particular emphasis on the most prevalent form of cyber-conflict, cyberwar. Conflicts occur on a daily basis, not always perceived by the general public, with both military and civilian infrastructure.
At the same time, we will analyze all the factors that make cyberwar a multidimensional tool in the hands of modern states as it is considered a "weapon", but it does not cause human losses at present, but its impact is mainly economic or psychological.
Finally, there will be examples of cyber warfare applications worldwide with the implications they have caused and useful conclusions and suggestions extracted from the survey.

Τα δίκτυα αρχικά ήταν απομονωμένα με συνέπεια να προσφέρουν την απαιτούμενη προστασία από κακόβουλους χρήστες. Παρ’ όλα αυτά, η ανάπτυξη της πληροφορικής σε συνδυασμό με την ανάγκη να τεθούν όλες αυτές οι υπηρεσίες στην ευχέρεια του πολίτη, προκειμένου να διευκολύνει την καθημερινότητα του σε όλα τα επίπεδα, τα κατέστησε ευρέως προσβάσιμα, οδηγώντας παράλληλα στην αύξηση της τρωτότητάς τους.
Σκοπός της παρούσας εργασίας είναι να παρουσιάσει τις μορφές των συγκρούσεων, που λαμβάνουν χώρα στον κυβερνοχώρο, δίνοντας ιδιαίτερη έμφαση στην πλέον διαδεδομένη μορφή κυβερνοσύγκρουσης, τον κυβερνοπόλεμο. Οι συγκρούσεις πραγματοποιούνται σε καθημερινή βάση, χωρίς να γίνονται πάντα αντιληπτές από το ευρύ κοινό, έχοντας εφαρμογή τόσο σε στρατιωτικές όσο και πολιτικές υποδομές.
Παράλληλα, θα αναλυθούν όλοι οι παράγοντες, οι οποίοι καθιστούν τον κυβερνοπόλεμο ως ένα πολυδιάστατο εργαλείο στα χέρια των σύγχρονων κρατών καθώς θεωρείται ως «όπλο», το οποίο όμως δεν προκαλεί ανθρώπινες απώλειες, προς το παρόν, αλλά ο αντίκτυπός του είναι κυρίως οικονομικός ή ψυχολογικός.
Τέλος, θα αναφερθούν παραδείγματα εφαρμογών κυβερνοπολέμου παγκοσμίως με τις επιπτώσεις, που προκάλεσαν καθώς και χρήσιμα συμπεράσματα και προτάσεις, που εξάγονται από την έρευνα.

Characterising the role of metabolic nuclear receptors: Farnesoid X receptor (FXR) and Liver X Receptor (LXR) in male fertility
Creators: name: Jarvis, Sheeba
Publisher: name: Imperial College London
Year: 2019

description: Both Farnesoid X receptors (FXR) and Liver X receptors (LXRs) are metabolic nuclear receptors which regulate bile acid and cholesterol homeostasis. A number of other biological functions are being increasingly described for these receptors in glucose metabolism, cardiorespiratory and renal disease, neurodegeneration, endocrine roles and in fertility. Until now there was little information about their likely roles in human male fertility. Both FXRα and LXR α/b act as transcription factors crucial for lipid homeostasis it is possible that their function or dysfunction may explain some cases of infertility. With a more overweight/obese population and rising prevalence of male fertility defects; identifying mechanisms and potential molecular targets is important. Form the work undertaken, I have shown that conjugated and unconjugated bile acids are present in the mouse and human testis with a specific BA signature and can potentially signal via BA receptors (FXR, TGR5, VDR, PXR) also characterised in the testis. Extensive studies undertaken in this project show that FXRα does not have a critical role in fertility, but BA may signal via other BA receptors such as TGR5 in the testis which is intriguing and required future studies. For LXRs in the testis, a comprehensive assessment of LXR signalling has been undertaken using multiple approaches including in vitro, ex vivo and in vivo models with consistent findings with regard to cholesterol efflux and lipogenic regulation. Additionally I have confirmed that in human testis LXR pathways are functional and there may be an association of defective LXR signalling in subfertility. Furthermore, using transcriptomic studies, novel LXR targets (notably LIPG, GSTM1, ALDH1L1) have been identified and with the use of a human testicular explant model are proven to relevant clinically and directly regulated by LXRs. Furthermore, an extensive assessment Lxrab- /- DKO mice using multi-omic integrated approaches has revealed potentially new roles for LXRs in glycolipid, sphingolipid balance and on phospholipase signalling which provides valuable new insights and sets the scene for future research. Finally, using a diet induced obesity model to study the effects of high fat on the testis, I uncovered a compensatory alteration in LXR signalling and deregulation of key proteins involved in maintaining the blood testis barrier, as well as crucial components for Androgen receptor signalling and lipid metabolism genes were altered testis in response to obesity. Together the work has brought new insights into the potential mechanisms between male infertility and lipid disorders and/or obesity in humans.

description: Στην παρούσα εργασία θα σχεδιαστούν σε κατάλληλο λογισμικό CAD/CAM και θα κατεργαστούν, πλήθος τεμαχίων αυξανόμενης δυσκολίας. Αρχικά, τα τεμάχια θα περιλαμβάνουν απλές εντολές προγραμματισμού σύμφωνα με τον κώδικα ISO. Στη συνέχεια, θα εκπονηθούν σχέδια και θα κατεργαστούν τεμάχια με κύκλους κατεργασίας ενώ τέλος θα γίνει κατεργασία πολυαξονικών τεμαχίων μέσω του λογισμικού CAD/CAM.

Τα τεμάχια που θα έχουν σχεδιαστεί θα κατασκευαστούν σε κέντρο κατεργασίας κυρίως με φραιζάρισμα ενώ όπου χρειασθεί θα χρησιμοποιηθεί και ο ψηφιακά καθοδηγούμενος τόρνος του Εργαστηρίου. Τα τελικά τεμάχια (3D) θα ενταχθούν σε βάση δεδομένων που πρόκειται να αναπτυχθεί στη συνέχεια.

Για την εκπόνηση της εργασίας θα χρησιμοποιηθεί το σύστημα CAD/CAM NX 11.0 της Siemens το οποίο διαθέτει το Εργαστήριο Μικροκοπής και Κατασκευαστικής Προσομοίωσης και τα τεμάχια θα κατεργαστούν στο ψηφιακά καθοδηγούμενο κέντρο κατεργασίας DMU50eco.

description: In this work, a number of pieces of increasing difficulty will be designed in a CAD / CAM software that will be processed. Initially, the pieces will include simple programming commands according to the ISO code. Subsequently, drawings will be made and machined workpieces will be processed, while multi-axis machining will be processed through the CAD / CAM software.

The pieces that will be designed will be made in a machining center mainly with milling, and where necessary, the digital guided lathe of the Laboratory. The final pieces (3D) will be integrated into a database to be developed later.

For the work, the Siemens CAD / CAM NX 11.0 system, which features the Microprocessor and Construction Simulation Laboratory, will be used and the workpieces will be processed at the DMU50eco digital guided processing center.

description: The problems encountered in the determination of m_u and m_d are discussed. While their sum is known quite well, the difference m_d-m_u, which measures the breaking of isospin symmetry in the QCD Lagrangian, is still subject to significant uncertainties. I focus on recent work based on the dispersive analysis of the decay eta -> 3 pi, which offers a good handle on isospin breaking, because in that transition, the contributions from the e.m. interaction are suppressed.

description: An explicit SUSY SU(12) unification model with three light chiral families is presented which avoids any external flavor symmetries. The hierarchy of quark and lepton masses and mixings is explained by higher dimensional Yukawa interactions involving Higgs bosons containing SU(5) singlet fields with VEVs appearing at or below the SUSY GUT scale of 2 \times 10^{16} GeV, approximately 50 times smaller than the SU(12) unification scale. The model has been found to be in good agreement with the observed quark and lepton masses and mixings, with nearly all prefactors of O(1) in the four Dirac and one Majorana fermion mass matrices.

Ortho-to-Para Ratio Studies of Shocked H2 Gas in the Two Supernova Remnants IC 443 and HB 21

description: We present near-infrared (2.5-5.0 μm) spectral studies of shocked H2 gas in the two supernova remnants IC 443 and HB 21, which are well known for their interactions with nearby molecular clouds. The observations were performed with Infrared Camera (IRC) aboard the AKARI satellite. At the energy range 7000 K <= E(v,J) <= 20000 K, the shocked H2 gas in IC 443 shows an ortho-to-para ratio (OPR) of 2.4+0.3-0.2, which is significantly lower than the equilibrium value 3, suggesting the existence of non-equilibrium OPR. The shocked gas in HB 21 also indicates a potential non-equilibrium OPR in the range of 1.8-2.0. The level populations are well described by the power-law thermal admixture model with a single OPR, where the temperature integration range is 1000-4000 K. We conclude that the obtained non-equilibrium OPR probably originates from the reformed H2 gas of dissociative J-shocks, considering several factors such as the shock combination requirement, the line ratios, and the possibility that H2 gas can form on grains with a non-equilibrium OPR. We also investigate C-shocks and partially-dissociative J-shocks for the origin of the non-equilibrium OPR. However, we find that they are incompatible with the observed ionic emission lines for which dissociative J-shocks are required to explain. The difference in the collision energy of H atoms on grain surfaces would make the observed difference between the OPRs of IC 443 and HB 21, if dissociative J-shocks are responsible for the H2 emission. Our study suggests that dissociative J-shocks can make shocked H2 gas with a non-equilibrium OPR.

Investigating biomechanical determinants of endothelial permeability in a hollow fibre bioreactor
Creators: name: Gray, Stephen Gerard
Publisher: name: Imperial College London
Year: 2020

description: The effect of haemodynamic stresses on endothelial permeability to macromolecules is important to normal physiology and in the pathogenesis of atherosclerosis. I developed and applied novel methods to evaluate effects on such transport of acute or chronic exposure to flow along and across cultured endothelium. Porcine aortic endothelial cells were isolated and cultured at passage 1-3 within the porous capillaries of a FiberCell bioreactor. At confluence they were exposed to acute (4 h) or chronic (3-10 day) steady or pulsatile luminal flow (mean shear 3.75 dyne/cm2), with or without transendothelial flow (4 x 10-7 cm/s). Permeability to rhodamine-labelled albumin was assessed by fluorimetry. Confluence of monolayers was confirmed by confocal and scanning electron microscopy and by demonstrating established effects of vasoactive agents on permeability: 10 U/ml thrombin increased permeability, as did 500 μM Nω-nitro-Larginine methyl ester, compared to controls. Permeability was increased by acute pulsatile shear and decreased by chronic pulsatile shear compared to static controls. A decrease in PECAM-1 expression under chronic pulsatile flow was demonstrated by flow cytometry. Steady flow gave higher permeability than pulsatile flow. The introduction of transendothelial flow increased apparent permeability more than could be explained by the addition of the convective transport itself. Preliminary studies suggested that albumin transport may partially be an active process and demonstrated the potential for engineered fibre walls that would allow effects of cyclic strain to be investigated. In conclusion, the hollow fibre bioreactor allowed endothelial permeability to be measured with or without exposure to luminal flow and transendothelial flow over 30 days, permitting the investigation of effects of mechanical stresses. Effects of shear stress varied with duration, pulsatility and direction relative to the endothelial surface.

description: Four new zinc(II) complexes, [ZnL2] (1), [ZnL(μ2-η1:η1-OAc)]n (2), [Zn2L2(μ1,1-N3)(μ1,3-N3)]n (3) and [ZnL(μ2-1,5-dca)]n (4), and a new nickel(II) complex, [Ni2L2(MeOH)2(μ1,1-N3)2] (5), where L is the deprotonated form of 5-bromo-(((2-(phenylamino)ethyl)imino)methyl)phenol (HL), OAc is acetate and dca is dicyanamide, were synthesized and characterized by elemental analyses, infrared and electronic spectroscopy, and single crystal X-ray determination. Complex 1 is a mononuclear zinc(II) compound, with the Zn(II) in tetrahedral coordination. Complexes 2, 3 and 4 are acetate, azide and dicyanamide bridged polymeric zinc(II) compounds, respectively, with the Zn(II) in distorted trigonal bipyramidal coordination. Complex 5 is an azide bridged dinuclear nickel(II) compound, with the Ni(II) ion having octahedral coordination. The compounds were evaluated for their antibacterial activities on Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Pseudomonas fluorescens and antifungal activities on Candida albicans and Aspergillus niger. Complexes 1 and 2 showed the most effective activity against B. subtilis and E. coli, with MIC values of 1.2–4.7 μM.

description: We consider a real massless scalar field in 3+1 dimensions satisfying a Robin boundary condition at a nonrelativistic moving mirror. Considering vacuum as the initial field state, we compute explicitly the number of particles created per unit frequency and per unit solid angle, exhibiting in this way the angular dependence of the spectral distribution. The well known cases of Dirichlet and Neumann boundary conditions may be reobtained as particular cases from our results. We show that the particle creation rate can be considerably reduced (with respect to the Dirichlet and Neumann cases) for particular values of the Robin parameter. Our results extend for 3+1 dimensions previous results found in the literature for 1+1 dimensions. Further, we also show that this inhibition of the dynamical Casimir effect occurs for different angles of particle emission.

description: We propose and analyze nonlinear optomechanical protocols that can be implemented by adding a single atom to an optomechanical cavity. In particular, we show how to engineer the environment in order to dissipatively prepare the mechanical oscillator in a superposition of Fock states with fidelity close to one. Furthermore, we discuss how a single atom in a cavity with several mechanical oscillators can be exploited to realize nonlinear many-body physics by stroboscopically driving the mechanical oscillators. We show how to prepare non-classical many-body states by either applying coherent protocols or engineering dissipation. The analysis of the protocols is carried out using a perturbation theory for degenerate Liouvillians and numerical tools. Our results apply to other systems where a qubit is coupled to a mechanical oscillator via a bosonic mode, e.g., in cavity quantum electromechanics.
