Electrochemical Processing of Metal Chalcogenides in Deep Eutectic Solvents

Subjects: Uncategorized

description: The increased need for metals in all aspects of life has resulted in attempts to make both primary extraction and secondary recycling of metals more efficient. This project investigates the use of DESs as an alternative to aqueous solutions for the dissolution of metal chalcogenides specifically, both in the form of minerals and synthetic semiconductors. The metals studied include silver, cadmium, zinc and lead with the biggest focus on copper. These compounds exhibit a wide range of properties and ultimate applications. Cd and Zn selenides and tellurides are important compounds in the ever-growing solar energy industry due to their small band gaps and high conductivities. Copper, in particular the sulphide minerals are an important source of Cu which is one of the most used metals worldwide.This study has demonstrated a novel method of investigating the electrochemical properties of minerals in DESs using paint casting. The currents observed are semiquantitative for the metal content of the mineral. Signals for both the metal and the chalcogenide could be distinguished in the voltammetry and these were similar to those for the individual components. The electrochemical signals for the minerals were similar to those for the pure compounds.Numerous sulfide, selenide and telluride compounds were studied in both the pure and mineral forms. It was found that during bulk electrolysis both components were solubilised, the speciation of the metals in solution were generally identified using UVVis spectroscopy coupled with EXAFS analysis. In most cases the metal speciation was dominated by the chloro-complexes and the chalcogenide was oxidised to an oxygen containing species. In all cases the solubilised metals could be recovered electrochemically by bulk electrolysis without cross contamination from the chalcogenide. The final part of the study showed that copper could be selectively won in a pure state from complex minerals like chalcopyrite.

description: We show that certain right-invariant metrics endow the infinite-dimensional Lie group of all smooth orientation-preserving diffeomorphisms of the circle with a Riemannian structure. The study of the Riemannian exponential map allows us to prove infinite-dimensional counterparts of results from classical Riemannian geometry: the Riemannian exponential map is a smooth local diffeomorphism and the length-minimizing property of the geodesics holds.

description: Galactic outflows produced by stellar feedback are known to be multiphase in nature. Both observations and simulations indicate that the material within several kpc of galactic disk mid-planes consists of warm clouds embedded within a hot wind. A theoretical understanding of the outflow phenomenon, including both winds and fountain flows, requires study of the interactions among thermal phases. We develop a method to quantify these interactions via measurements of mass, momentum, and energy flux exchanges using temporally and spatially averaged quantities and conservation laws. We apply this method to a star-forming ISM MHD simulation based on the TIGRESS framework, for Solar neighbourhood conditions. To evaluate the extent of interactions among the phases, we first examine the validity of the ``ballistic model,'' which predicts trajectories of the warm phase ($5050\,\rm{K}5\times10^5\,\rm{K}$) to the warm phase. The large energy flux from the hot outflow that is transferred to the warm and intermediate phases is quickly radiated away. A simple interaction model implies an effective warm cloud size in the fountain flow of a few 100~pc, showing that warm-hot flux exchange mainly involves a few large clouds rather than many small ones.

description: The recent emergence of a new coronavirus (COVID-19) has gained a high cover in public media and worldwide news. The virus has caused a viral pneumonia in tens of thousands of people in Wuhan, a central city of China. This short paper gives a brief introduction on how the demand for information on this new epidemic is reported through Google Trends. The reported period is 31 December 2020 to 20 March 2020. The authors draw conclusions on current infodemiological data on COVID-19 using three main search keywords: coronavirus, SARS and MERS. Two approaches are set. First is the worldwide perspective, second - the Chinese one, which reveals that in China this disease in the first days was more often referred to SARS then to general coronaviruses, whereas worldwide, since the beginning, it is more often referred to coronaviruses.

description: We predict three full Heusler compounds XInPd2 (X = Zr, Hf and Ti) to be potential candidates for type-II Dirac semimetals. The crystal symmetry of these compounds have appropriate chemical environment with a unique interplay of inversion, time reversal and mirror symmetry. These symmetries help to give six pairs of type-II Dirac nodes on the C_4 rotation axis, closely located at/near the Fermi level. Using first principle calculations, symmetry arguments and crystal field splitting analysis, we illustrate the occurrence of such Dirac nodes in these compounds. Bulk Fermi surfaces have been studied to understand the Lorentz symmetry breaking and Lifshitz transition (LT) of Fermi surfaces. Bulk nodes are projected on the (001) and (111) surfaces which form the surface Fermi arcs, that can further be detected by probes such as angle resolved photo-emission and scanning tunneling spectroscopy. By analyzing the evolution of arcs with changing chemical potential, we prove the fragile nature and the absence of topological protection of the Dirac arcs. Our predicted compounds overcome the limitations of the previously reported PtTe2 class of compounds.

description: We study numerically the Sherrington--Kirkpatrick model as function of the magnetic field h, with fixed temperature T=0.6 Tc. We investigate the finite size scaling behavior of several quantities, such as the spin glass susceptibility, looking for numerical evidences of the transition on the De Almeida Thouless line. We find strong corrections to scaling which make difficult to locate the transition point. This shows, in a simple case, the extreme difficulties of spin glass simulations in non-zero magnetic field. Next, we study various sum rules (consequences of stochastic stability) involving overlaps between three and four replicas, which appear to be numerically well satisfied, and in a non-trivial way. Finally, we present data on P(q) for a large lattice size (N=3200) at low temperature T=0.4 Tc, where, for the first time, the shape predicted by the RSB solution of the model for non-zero magnetic field is visible.

description: We use Gaia DR2 systemic proper motions of 45 satellite galaxies to constrain the mass of the Milky Way using the scale free mass estimator of Watkins et al. (2010). We first determine the anisotropy parameter $β$, and the tracer satellites' radial density index $γ$ to be $β$=$-0.67^{+0.45}_{-0.62}$ and $γ=2.11\pm0.23$. When we exclude possible former satellites of the Large Magellanic Cloud, the anisotropy changes to $β$=$-0.21^{+0.37}_{-0.51}$. We find that the index of the Milky Way's gravitational potential $α$, which is dependent on the mass itself, is the parameter with the largest impact on the mass determination. Via comparison with cosmological simulations of Milky Way-like galaxies, we carried out a detailed analysis of the estimation of the observational uncertainties and their impact on the mass estimator. We found that the mass estimator is biased when applied naively to the satellites of simulated Milky Way halos. Correcting for this bias, we obtain for our Galaxy a mass of $0.58^{+0.15}_{-0.14}\times10^{12}$M$_\odot$ within 64 kpc, as computed from the inner half of our observational sample, and $1.43^{+0.35}_{-0.32}\times10^{12}$M$_\odot$ within 273 kpc, from the full sample; this latter value extrapolates to a virial mass of $M_\mathrm{vir\,Δ=97}$=$1.51^{+0.45}_{-0.40} \times 10^{12}M_{\odot}$ corresponding to a virial radius of R$_\mathrm{vir}$=$308\pm29$ kpc. This value of the Milky Way mass lies in-between other mass estimates reported in the literature, from various different methods.

description: In this work we develop a new method of diagnosing the nervous system diseases and a new approach in studying human gait dynamics with the help of the theory of discrete non-Markov random processes. The stratification of the phase clouds and the statistical non-Markov effects in the time series of the dynamics of human gait are considered. We carried out the comparative analysis of the data of four age groups of healthy people: children (from 3 to 10 year olds), teenagers (from 11 to 14 year oulds), young people (from 21 up to 29 year oulds), elderly persons (from 71 to 77 year olds) and Parkinson patients. The full data set are analyzed with the help of the phase portraits of the four dynamic variables, the power spectra of the initial time correlation function and the memory functions of junior orders, the three first points in the spectra of the statistical non-Markov parameter. The received results allow to define the predisposition of the probationers to deflections in the central nervous system caused by Parkinson's disease. We have found out distinct differencies between the five submitted groups. On this basis we offer a new method of diagnostics and forecasting Parkinson's disease.

description: We suggest that the dynamics of stable viscous invasion fronts in porous media depends on the volume capacitance of the media. At high volume capacitance, our network simulations provide numerical evidence of a scaling relation between the front width and its velocity. In the low volume capacitance regime, we derive a new effective scaling supported by network simulations and is in agreement with previous experiments on imbibition in paper and collections of glass beads.

description: We perform three-dimensional numerical simulations of surface flows on the companion star in a semi-detached binary system and construct the corresponding Doppler maps. The mass ratio of the binary system, $q=M_2/M_1$, considered here is $q=0.05, 0.33, 0.5, 1, 2$, and 3. For all cases, we obtain the H-, L1-, and L2-eddies, as found in our previous work, and confirm that the flow pattern does not heavily depend on the mass ratio. We propose that this kind of problem be dubbed ``{\it stellar meteorology}.'' The Doppler maps at the position of the companion show a structure tilted towards clockwise direction and presenting deviations from the critical Roche surface due to the L1-eddy and the L2-eddy on the companion star. We apply our results to the Galactic supersoft X-ray source RX J0019.8+2156 and try to attribute the low radial velocity component of the emission lines of He II $λ4686$ observed recently to the irradiated spot on the surface of the companion rather than that of the white dwarf or the accretion disc. Based on the comparison between the observations and our constructed Doppler map, we estimate the mass of the companion star in RX J0019.8+2156 to be $\sim 2 M_{\odot}$ assuming the mass of the white dwarf star to be around $0.6 M_{\odot}$.

Reshaping the Archive: Exhibition as a mechanism for change
Creators: name: Lester, Peter Anthony
Publisher: name: University of Leicester
Year: 2020
Subjects: Uncategorized

description: This thesis examines the recent phenomenon of physical exhibition-making within archives. It investigates how physical exhibitions are conceived and made in archives and their role in reimagining new ways for audiences to experience archival collections. Situated within a context of increasing digitisation, declining onsite visits to archives and progressively reduced finances, the research more broadly considers the role of exhibition in wider restructurings of archival spaces and organisations. It examines how and why archivists seek to transform the physical experience of being in public archives, thereby making archives more relevant and meaningful to people’s lives. The research uses an interdisciplinary methodology and develops a theoretical framework which draws on the spatial and phenomenological ideas of Henri Lefebvre and Maurice Merleau-Ponty to re-examine archival exhibition practice. The research comprises a broad, international survey of exhibition practice and two detailed case studies. The thesis makes a contribution to knowledge by developing understanding around archive exhibition, based upon a broad yet detailed body of research findings and an innovative theoretical and methodological approach; and has potential impact both in terms of archival theory and practice. The thesis argues that existing discussions of exhibition within archival literature are largely framed through a discourse of justification; whilst exhibition is principally conceived as a form of outreach. Drawing across a whole range of recent archival practice, the thesis shows that exhibition is, rather, part of a pluralising of experience that recognises distinct and diverse audiences and uses. In this sense, exhibition is understood not only as a form of promotion but also as a means of encounter and as a site of discussion and debate. Moreover, the thesis proposes wider implications for the space of the archive as a cultural venue and meeting place.

The Role of DNA Methylation in Arthropods.
Creators: name: Marshall, Hollie Jade
Publisher: name: University of Leicester
Year: 2020
Subjects: Uncategorized

description: Epigenetic mechanisms, such as DNA methylation, are poorly understood in arthropods compared to mammals and plants. Arthropods have been shown to display a varietyof DNA methylation profiles across species, making them ideal for understanding the function of DNA methylation outside of a mammalian context. This thesis explores therole of DNA methylation in two arthropod species; the eusocial bumblebee, Bombus terrestris and the freshwater crustacean Daphnia magna.Previous research has implicated DNA methylation in caste determination in some social insect species. I have found differentially methylated genes between worker castesof B. terrestris, some of which are involved in reproduction. However, there was no direct link with differentially expressed genes. This indicates DNA methylation doesnot causally affect gene expression differences between castes.Another possible function of DNA methylation in B. terrestris is the regulation of imprinted genes. Imprinted genes are those which display parent-of-origin allele-specificexpression. Predictions based on the kinship theory state imprinted genes should exist in B. terrestris. I have identified parent-of-origin expression in this species, indicatingsome support for the kinship theory. However, DNA methylation does not appear to be directly mediating this process.The final chapter of this thesis identified DNA methylation changes through time in a single resurrected population of D. magna. A small number of genes which exhibitedDNA methylation changes over time were involved in the production of males, which is usually triggered by environmental change. The data generated in this chapter will be used for novel analyses investigating the adaptive potential of DNA methylation.This thesis has contributed new knowledge to three fields: caste determination in social insects, imprinted genes in social insects and adaptive epigenetics. Taken as a whole, the studies presented here highlight the need for functional validation and the consideration of genotype in future ecological epigenetic research.

description: We solve for the finite temperature collective mode dynamics in the Holstein-double exchange problem, using coupled Langevin equations for the phonon and spin variables. We present results in a strongly anharmonic regime, close to a polaronic instability. For our parameter choice the system transits from an `undistorted' ferromagnetic metal at low temperature to a structurally distorted paramagnetic insulator at high temperature, through a short range charge ordered (CO) phase near the ferromagnetic crossover at $T_{FM}$. The small amplitude harmonic phonons at low temperature cross over to large amplitude dynamics around $0.5 T_{FM}$ due to thermally generated short range correlated polarons. The rare thermal ``tunneling'' of CO domains generates a hitherto unknown momentum selective spectral weight at very low energy. We compare our results to inelastic neutron data in the manganites and suggest how the singular low energy features can be probed.

We show that the $β$ and $β''$ phases found in the precipitation sequence are characterised by the presence of covalent bonds between Si-Si nearest neighbour pairs and covalent/ionic bonds between Mg-Si nearest neighbour pairs. We then investigate the stability of two recently discovered precipitate phases, U1 and U2, both containing Al in addition to Mg and Si. We show that both phases are characterised by tightly bound Al-Si networks, made possible by a transfer of charge from the Mg atoms.

Calibrating an Adaptive Farmer-Joshi Agent-Based Model for Financial Markets

description: This report is published in fulfilment of an honours degree in statistics. The project explores the calibration and simulation of the Farmer and Joshi (2002) agent-based model of financial markets using the method of moments along with a genetic algorithm and a Nelder-Mead with threshold accepting algorithm. The model is used for understanding daily trading decisions made from closing auction to closing auction in equity markets, as it attempts to model financial market behaviour without the inclusion of agent adaptation. However, our attempt at calibrating the model has limited success in replicating important stylized facts observed in financial markets, similar to what has been found in other calibration experiments of the model. This leads us to extend the Farmer-Joshi model to include agent adaptation using a Brock-Hommes (1998) approach to strategy fitness based on trading strategy proﬁtability. The adaptive Farmer-Joshi model allows trading agents to switch between strategies, favouring strategies that have been more profitable over some period of time determined by a free-parameter determining the profit monitoring time-horizon.

description: GRB 190114C is the first GRB for which the detection of very-high energy emission up to the TeV range has been reported. It is still unclear whether environmental properties might have contributed to the production of these very high-energy photons, or if it is solely related to the released GRB emission. The relatively low redshift of the GRB (z=0.425) allows us to study the host galaxy of this event in detail, and to potentially identify idiosyncrasies that could point to progenitor characteristics or environmental properties responsible for such a unique event. We use ultraviolet, optical, infrared and submillimetre imaging and spectroscopy obtained with HST, VLT and ALMA to obtain an extensive dataset on which the analysis of the host galaxy is based. The host system is composed of a close pair of interacting galaxies (Delta v = 50 km s^-1), both of which are well-detected by ALMA in CO(3-2). The GRB occurred within the nuclear region (~170 pc from the centre) of the less massive but more star-forming galaxy of the pair. The host is more massive (log(M/M_odot)=9.3) than average GRB hosts at that redshift and the location of the GRB is rather unique. The enhanced star-formation rate was probably triggered by tidal interactions between the two galaxies. Our ALMA observations indicate that both host galaxy and companion have a high molecular gas fraction, as has been observed before in interacting galaxy pairs. The location of the GRB within the core of an interacting galaxy with an extinguished line-of-sight is indicative of a denser environment than typically observed for GRBs and could have been crucial for the generation of the very-high-energy photons that were observed.

description: Die richtige Studienwahl, die Spaß bringt, finanzielle Freiheiten eröffnet, Sicherheit verspricht und eine individuelle Karrieregestaltung ermöglicht – wer will das nicht? Mit einem MINT-Studium kann all das erreichbar sein. Der Weg dorthin ist oft steinig, oder die Entscheidung fällt schwer, sodass es viele MINT-Orientierungsangebote gibt, die gerade junge Frauen in dieser Wegfindungsphase unterstützen. Im November 2015 startete die Gleichstellungsinitiative „Make up your MINT – praxisnah, interaktiv, multimedial“ in Zusammenarbeit von Prof. Dr. Korinna Bade vom Fachbereich „Informatik und Sprachen“ und Tom Guba vom Fachbereich „Angewandte Biowissenschaften und Prozesstechnik“ (im folgenden nur noch als „Fachbereiche“ bezeichnet) an der Hochschule Anhalt. Passend zu drei großen Projektschwerpunkten nämlich Videoproduktion, Praktikum und Vermarktung – wurde ein Projektteam zusammengestellt, das sich der Aufgabe annahm, persönliche und berufliche Perspektiven im MINT-Bereich im Land Sachsen-Anhalt aufzeigen und über Videos das Interesse an MINT zu wecken.

description: In order to cope with situations in which a plant's dynamics are not precisely known, we consider the problem of supervisory control for a class of discrete event systems modelled by fuzzy automata. The behavior of such discrete event systems is described by fuzzy languages; the supervisors are event feedback and can disable only controllable events with any degree. The concept of discrete event system controllability is thus extended by incorporating fuzziness. In this new sense, we present a necessary and sufficient condition for a fuzzy language to be controllable. We also study the supremal controllable fuzzy sublanguage and the infimal controllable fuzzy superlanguage when a given pre-specified desired fuzzy language is uncontrollable. Our framework generalizes that of Ramadge-Wonham and reduces to Ramadge-Wonham framework when membership grades in all fuzzy languages must be either 0 or 1. The theoretical development is accompanied by illustrative numerical examples.

description: The heavy baryon system bounded by the strong interaction has a rich internal structure, so its mass spectra can have the fine structure similar to the line spectra of atom bounded by the electromagnetic interaction. We systematically study the internal structure of $P$-wave $Ω_b$ baryons and calculate their $D$-wave decay properties. The present study, together with our previous studies on their mass spectra and $S$-wave decay properties, suggest that all the four excited $Ω_b$ baryons recently discovered by LHCb can be well explained as $P$-wave $Ω_b$ baryons, and their beautiful fine structure is directly related to the rich internal structure of $P$-wave $Ω_b$ baryons.

description: Acetylcholine receptor antibody-positive generalized myasthenia gravis (gMG) is effectively treated with symptomatic and immunosuppressive drugs but a proportion of patients has a persistent disease and severe adverse events (AEs). The unmet medical needs are specific immunosuppression and AE lowering. Eculizumab blocks C5 protecting neuromuscular junction from the destructive autoantibody effects. Phase II (Study C08-001) and III (ECU-MG-301) studies, with the open-label extension (ECU-MG-302), demonstrated eculizumab efficacy and safety in refractory gMG patients. We provide an overview of eculizumab biological features, clinical efficacy, and safety in gMG patients, highlighting our perspective on the drug positioning in the MG treatment algorithm. Eculizumab has the potential to significantly change the immunosuppressive approach in gMG offering the opportunity to avoid or delay corticosteroids’ use due to its speed and selective mechanism of action. Eculizumab prescription will depend on: 1. ability to modify the natural disease course; 2. sustainability in the clinical practice (cost/effectiveness ratio); 3. drug-induced AE reduction. At present we are missing a controlled study on its use as a first-line treatment. We think that immunosuppression in MG will change significantly in the next years by adopting more focused ‘Precision Medicine’ approaches, and Eculizumab seems to satisfy such a promise.

description: Accurate and precise measurements of masses of galaxy clusters are key to derive robust constraints on cosmological parameters. Rising evidence from observations, however, confirms that X-ray masses, obtained under the assumption of hydrostatic equilibrium, might be underestimated, as previously predicted by cosmological simulations. We analyse more than 300 simulated massive clusters, from `The Three Hundred Project', and investigate the connection between mass bias and several diagnostics extracted from synthetic X-ray images of these simulated clusters. We find that the azimuthal scatter measured in 12 sectors of the X-ray flux maps is a statistically significant indication of the presence of an intrinsic (i.e. 3D) clumpy gas distribution. We verify that a robust correction to the hydrostatic mass bias can be inferred when estimates of the gas inhomogeneity from X-ray maps (such as the azimuthal scatter or the gas ellipticity) are combined with the asymptotic external slope of the gas density or pressure profiles, which can be respectively derived from X-ray and millimetric (Sunyaev-Zeldovich effect) observations. We also obtain that mass measurements based on either gas density and temperature or gas density and pressure result in similar distributions of the mass bias. In both cases, we provide corrections that help reduce both the dispersion and skewness of the mass bias distribution. These are effective even when irregular clusters are included leading to interesting implications for the modelling and correction of hydrostatic mass bias in cosmological analyses of current and future X-ray and SZ cluster surveys.

description: Four XMM-Newton observations of the core of M31, spaced at 6 month intervals, show that the brightest point X-ray source, RX J0042.6+4115, has a 0.4-10 keV luminosity of ~5 10^38 erg/s, and exhibits significant variability in intensity and X-ray spectrum over a time scale of ~100 s including hard flares; such behaviour is only observed in Z-sources and transient blackhole binaries in our Galaxy. The lightcurves, X-ray spectra and hardness-intensity data from the four XMM-Newton observations all strongly suggest that it is a Z-source, bringing the total number of known Z-sources to nine.

The Human–Nature Relationship and Its Impact on Health: A Critical Review
Creators: name: Bell, Marvin
Publisher: name: figshare
Year: 2022
Subjects: Health Care

description: Within the past four decades, research has been increasingly drawn toward understanding whether there is a link between the changing human–nature relationship and its impact on people’s health. However, to examine whether there is a link requires research of its breadth and underlying mechanisms from an interdisciplinary approach. This article begins by reviewing the debates concerning the human–nature relationship, which are then critiqued and redefined from an interdisciplinary perspective. The concept and chronological history of “health” is then explored, based on the World Health Organization’s definition. Combining these concepts, the human–nature relationship and its impact on human’s health are then explored through a developing conceptual model. It is argued that using an interdisciplinary perspective can facilitate a deeper understanding of the complexities involved for attaining optimal health at the human–environmental interface. __________________________

description: The proximity effect in SF structures was examined. It is shown that, due to the oscillations of the induced superconducting order parameter in a ferromagnet, the critical temperature of an SF-bilayer becomes minimal when the thickness of the ferromagnetic layer is close to a quarter of the period of spatial oscillations. It is found that the spontaneous vortex state arisen in the superconductor due to the proximity of the magnetic domain structure of a ferromagnet brings about noticeable magnetoresistive effects.
