title: Temperature Dependent Spectroscopic Studies of HiPco SWNT Composites
titleType: Other
Creators: name: Keogh, Sinead
Publisher: name: TU Dublin
Year: 2005

description: Hybrid systems of the conjugated organic polymer poly(p-phenylene vinylene-co-2,5-dioctyIoxy-m-phenylene vinylene)(PmPV) and HiPco SWNTs are explored using spectroscopic and thermal techniques to determine specific interactions. Vibrational spectroscopy indicates a weak interaction and this is further elucidated using Differential Scanning Calorimetry, Temperature Dependent Raman Spectroscopy and Temperature Dependent Infrared Spectroscopy of the raw materials and the composite. An endothermic transition is observed in the DSC of both the polymer and the 0.1% HiPco composite in the region of 60 °C. Also observed in the DSC of the composite is a doubly peaked endotherm at -39 °C and -49 °C, which does not appear in the polymer film. The Raman of the polymer backbone upon increasing the temperature to 60 °C shows diminished phenyl Ag modes at 1557 cm−1 and 1575 cm−1, with an increase in the relative intensity of the vinyl mode at 1630 cm−1. This change in the Raman of the polymer is translated to the Raman of the composite upon increase to 60 °C, where the spectrum becomes abruptly dominated by nanotubes. The Raman of the composite shows no change in the lower temperature regions, however infrared suggests that the transition at -39 °C derives from an interaction with the polymer side chains. The composite at -39 °C shows a change in the absorption of the polymer side chain aryl-oxide linkage at 1250 cm−1. while Raman suggests a change to the polymer backbone configuration at 60 °C. Implications are discussed.
title: Controlling the Optical Properties of a Conjugated Co-polymer through Variation of Backbone Isomerism and the Introduction of Carbon Nanotubes

description: The need to control the formation of weakly emitting species in polymers such as aggregates and excimers, which are normally detrimental to device performance, is illustrated for the example of the polymer poly(m-phenylenevinylene-co-2,5-dioctyloxy-p-phenylenevinylene), using the model compound, 2,5-dioctyloxy-p-distyrylbenzene as a comparison. Two different methods, namely a Homer-Emmons polycondensation in dimethylformamide (DMF) and a Wittig polycondensation in dry toluene, have been used during synthesis resulting in a polymer with a predominantly trans-vinylene backbone and a polymer with a predominantly cis-vinylene backbone, respectively. Photoluminescence and absorption spectroscopy indicate that the polymer forms aggregate species in solution with spectra that are distinctly red-shifted from those associated with the intra-chain exciton. Concentration dependent optical studies were used to probe the evolution of aggregation in solution for both polymers. The results indicate that inter-chain coupling in the predominantly cis-polymer is prominent at lower concentrations than in the case of the trans-counterpart. These results are supported by pico-second pump and probe transient absorption measurements where, in dilute solutions, the polymer in a cis-configuration exhibits highly complex excited state dynamics, whereas the polymer in a trans-configuration behaves similarly to the model compound. It is proposed therefore that the degree of backbone isomerism has a profound impact on the morphology of the polymeric solid and control over it is a route towards optimising the performance of the material in thin film form. Another method to inhibit inter-chain effects using multi walled carbon nanotubes (MWNT) as nano-spacers in the polymer solutions is proposed. By comparison to spectroscopic analysis, aggregation effects are shown to be reduced by the introduction of nanotubes. Electron microscopy and computer simulation suggest a well-defined interaction between the polymer backbone and the lattice of the nanotube.

title: Structural Property Relationships in Conjugated Polymers
titleType: Other
Creators: name: O'Neill, Luke
Publisher: name: TU Dublin
Year: 2005

description: A series of π conjugated oligomers were studied by absorption and photoluminescence spectroscopy. A linear relationship between the positioning of the absorption and photoluminescence maxima plotted against inverse conjugation length is observed. The relationships are in good agreement with the simple particle in a box method, one of the earliest descriptions of the properties of one-dimensional organic molecules. In addition to the electronic transition energies, it was observed that the Stokes shift also exhibited a well-defined relationship with increasing conjugation length, implying a correlation between the electron-vibrational coupling and chain length. This correlation is further examined using Raman spectroscopy, whereby the integrated Raman scattering is seen to behave superlinearly with chain length. There is a clear indication that the vibrational activity and thus nonradiative decay processes are controllable through molecular structure. The correlations between the Stokes energies and the vibrational structure are also observed in a selection of PPV based polymers and a clear trend of increasing luminescence efficiency with decreasing vibrational activity and Stokes shift is observable. The implications of such structure property relationships in terms of materials design are discussed.

description: We give a theory of the inverse spin Hall effect (ISHE) in ferromagnetic metals based on skew scattering via collective spin fluctuations. This extends Kondo's theory of the anomalous Hall effect (AHE) to include short-range spin-spin correlations. We find a relation between the ISHE and the four-spin correlations near the Curie temperature TC. Such four-spin correlations do not contribute to the AHE, which relates to the three-spin correlations. Thus our theory shows an essential difference between the AHE and ISHE, providing an essential complement to Kondo's classic theory of the AHE in metals. We note the relation to skew-scattering mechanisms based on impurity scattering. Our theory can be compared to recent experimental results byWei et al. [Nat. Commun. 3, 1058 (2012)] for the ISHE in ferromagnetic alloys.

description: Charge transfer in homogeneous nucleotide chains is modeled on the basis of Holstein Hamiltonian. The path length of Davydov solitons in these chains is being studied. It is shown that in a dispersionless case, when the soliton velocity V is small, the path length grows exponentially as V decreases. In this case the state of a moving soliton is quasisteady. In the presence of dispersion determined by the dependence $Ω^2 = Ω_0^2 + V_0^2κ^2$ \, the path length in the region 0 < V < V_0 is equal to infinity. In this case the phonon environment follows the charge motion. In the region V > V_0 the soliton motion is accompanied by emission of phonons which leads to a finite path length of a soliton. The latter tends to infinity as $V \rightarrow V_0 + 0$ and $V \rightarrow \infty$. The presence of dissipation leads to a finite soliton path length. An equilibrium velocity of soliton in an external electric field is calculated. It is shown that there is a maximum intensity of an electric field at which a steady motion of a soliton is possible. The soliton mobility is calculated for the stable or ohmic brunch.

description: A distributed quantum network would require quantum nodes capable of performing arbitrary quantum information protocols with high fidelity. So far the challenge has been in realizing such quantum nodes with features for scalable quantum computing. We show here that using the solid-state spins in 4H-Silicon Carbide (4H-SiC) such a goal could be realized, wherein a controlled generation of highly coherent qubit registers using nuclear spins is possible. Using a controlled isotope concentration and coherent control we perform here atomistic modeling of the central spin system formed by the electron spin of a silicon vacancy color center ($V_{Si}^-$-center) and the non-interacting nuclear spins. From this we lay out conditions for realizing a scalable nuclear-spin ($^{13}C$ or $^{29}Si$) register, wherein independent control of the qubits alongside their mutual controlled operations using the central electron spin associated to the $V_{Si}^-$-center in 4H-SiC are achieved. Further, the decoherence and entanglement analysis provided here could be used to evaluate the quantum volume of these nodes. Our results mark a clear route towards realizing scalable quantum memory nodes for applications in distributed quantum computing networks and further for quantum information protocols.

description: In this paper a candidate protocol to replace the prevalent CSMA/CA medium access control in Wireless Local Area Networks is presented. The proposed protocol can achieve higher throughput than CSMA/CA, while maintaining fairness, and without additional implementation complexity. Under certain circumstances, it is able to reach and maintain collision-free operation, even when the number of contenders is variable and potentially large. It is backward compatible, allowing for new and legacy stations to coexist without degrading one another's performance, a property that can make the adoption process by future versions of the standard smooth and inexpensive.

Creators: name: Ruvio, G

Year: 2018

description: In this paper microwave thermal ablation is numerically evaluated in the context of a treatment for Conn’s Syndrome. This condition is caused by a benign shallow tumour in the cortex of adrenal gland. The modelling and design of microwave applicator to deliver thermal ablation to the adrenal gland requires accurate tissue characterisation. Measuring the dielectric properties of the constituent tissues in the adrenal gland, i.e. cortex and medulla, enables more accurate numerical modelling for electromagnetic and thermal simulations. This study presents an anatomically and dielectrically realistic numerical model of the adrenal gland, and investigates the feasibility of applying controlled heating to small targets in the adrenal cortex. In addition, the use of dielectric contrast between the fat and the cortex of the adrenal gland to focus the thermal energy in the gland has also been studied. Being conscious of limitations of numerical simulation of complex multiphysics problems like the microwave ablative treatment, calculated results provide a preliminary description of the electromagnetic and thermal phenomena involved.

description: Representation learning is the first step in automating tasks such as research paper recommendation, classification, and retrieval. Due to the accelerating rate of research publication, together with the recognised benefits of interdisciplinary research, systems that facilitate researchers in discovering and understanding relevant works from beyond their immediate school of knowledge are vital. This work explores different methods of research paper representation (or document embedding), to identify those methods that are capable of preserving the interdisciplinary implications of research papers in their embeddings. In addition to evaluating state of the art methods of document embedding in a interdisciplinary citation prediction task, we propose a novel Graph Neural Network architecture designed to preserve the key interdisciplinary implications of research articles in citation network node embeddings. Our proposed method outperforms other GNN-based methods in interdisciplinary citation prediction, without compromising overall citation prediction performance.

description: We present a detailed analysis of the formation, evolution, and possible longevity of metallicity gradients in simulated dwarf galaxies. Specifically, we investigate the role of potentially orbit-changing processes such as radial stellar migration and dynamical heating in shaping or destroying these gradients. We also consider the influence of the star formation density threshold, investigating both a low and high value (0.1 amu/$cm^{3}$ - 100 amu/$cm^{3}$). The Nbody-SPH models that we use to self-consistently form and evolve dwarf galaxies in isolation show that, in the absence of significant angular momentum, metallicity gradients are gradually built up during the evolution of the dwarf galaxy, by ever more centrally concentrated star formation adding to the overall gradient. Once formed, they are robust, survive easily in the absence of external disturbances and hardly decline over several Gyr, and they agree well with observed metallicity gradients of dwarf galaxies in the Local Group. The underlying orbital displacement of stars is quite limited in our models, being of the order of only fractions of the half light radius over time-spans of 5 to 10 Gyr in all star formation schemes. This is contrary to the strong radial migration found in massive disc galaxies, caused by scattering of stars off the corotation resonance of spiral structures. In the dwarf regime the stellar body only seems to undergo mild dynamical heating, due to the lack of long-lived spiral structures and/or discs. The density threshold has profound influences on the star formation mode of the models, but only a minor influence on the evolution of metallicity gradients. Increasing the threshold 1000-fold causes comparatively stronger dynamical heating of the stellar body due to the increased turbulence and the scattering of stars off dense gas clouds, but the effect remains very limited in absolute terms.

description: The study examines the influence of modern climate changes on the precipitation and temperature regime in the southern and southeastern regions of the Great Caucasus natural region. Also, determining the multi-year trends of the temperature and precipitation regime in 1991-2020 and investigating their change regularities is the goal. At the same time, in the article, the variability of monthly, seasonal and annual indicators was studied in the multi-year period. The impact of global climate changes on the perennial precipitation regime in the southern part of the Greater Caucasus region was studied. In the analysis, the precipitation observation data of 8 meteorological stations during the years 1991-2020 were used. Multi-year (1991-2020) various indicators of precipitation were compared with the base quantities. In the study, the multi-year period was considered for 2 periods (1991-2005, 2006-2020) and the monthly, seasonal and annual trends of precipitation were compared. The study found that the multi-year average temperature in the province for the last 30 years was 11-140C in the lowlands and 6-70C in the mid-mountains. However, compared to 1961-1990, the perennial temperature has increased by 1.00C. The amount of annual precipitation was in the interval of 300-1300 mm, depending on the stations. A decrease in the amount of precipitation has been recorded for many years, and in some places this amount has even increased to 27%.

description: The electric transport properties of superconducting FeSe0.3Te0.7/Au c-axis (S/N) junctions, fabricated by using Pulsed Laser Deposition technique, have been investigated in the temperature range of 2 K to the superconducting transition temperature TC ~ 13.5 K, and in the presence of applied magnetic fields from 0 to 9 T. A large zero bias conductance peak has always been observed in the conductance spectra of several batches of junctions. In addition, we have also found several gap-like features. Using the extended BTK theory with the currently favored nodeless S+- wave symmetry, our conductance spectrum can be reproduced quite well in the low bias range with Δ1 = 4 meV, and Δ2 = 6 meV at 2 K. However the experimental conductance spectrum is substantially below the calculated one in the high bias range. Furthermore, there is a conductance minimum at about 20 meV, which may be the reason for the discrepancy.

description: A new method (CWBM) is proposed for calculating the water balance of the territory and water resources of rivers. CWBM was developed on the basis of reliable scientific sources (satellite images, GIS-technologies, modern scientific approaches, advanced hydrological models). The following scientific innovations were achieved for the first time in the new method: 1. Considering the soil-water-air environment (SWA) as a single mechanism, the influence of complex flow-forming factors has been studied. 2. It was possible to obtain quantitative expression of the impact of each factor on water resources separately and together. 3. In the research process, time-space restrictions and dependence on observational data have been eliminated. 4. By carrying out 3-stage studies (past, present, future), it is possible to receive prompt and adequate responses to any changes and perform multi-scenario forecasting. 5. In any river basins with different physical-geographical conditions, it is possible to estimate both the total runoff separately and as a sum of the surface runoff and base flow. Comparison of the actual and calculated with CWBM method flow for 113 river basins of Azerbaijan shows that the error between them was up to 10% for 92 and 10-15% for 21 rivers.

description: We present the first evidence that Oosterhoff type II globular clusters exist in the Andromeda galaxy (M31). On the basis of time-series photometry of the moderately metal-poor ([Fe/H]\sim -1.6 dex) M31 globular cluster G11, obtained with the Wide Field Planetary Camera 2 on board the Hubble Space Telescope, we detected and derived periods for 14 RR Lyrae stars, of which five are found to lie inside the cluster tidal radius. They include three fundamental-mode (RRab) and two first-overtone (RRc) pulsators, with average periods = 0.70 d, and = 0.40 d, respectively. These mean periods and the position of the cluster variable stars in the period-amplitude and period-metallicity diagrams, all suggest that G11 is likely to be an Oosterhoff type II globular cluster. This appears to be in agreement with the general behavior of Milky Way globular clusters with similar metallicity and horizontal branch morphology.

description: The environment of the Baltic Sea is heavily influenced by human activities. In addition, the region is undergoing significant changes in the face of global climate change. Therefore, it is necessary to assess the state of the environment and greenhouse gas emissions in the region. In 2022, the Programme for the development of the system of climate and environmental monitoring of the Russian seas was launched. For the Baltic Sea, the spatial and temporal scheme of the regional monitoring module has been designed to carry out long-term, regular, and large-scale surveys. The satellite monitoring is based on the analysis of radiometer data and includes analyses of the spatial and temporal variability of suspended particulate matter and chlorophyll a concentrations, as well as sea surface temperature. The shipboard monitoring consists of seasonal and monthly surveys. The coastal monitoring is based on data from sensors installed on a 57-m met tower as a permanent climate and environmental monitoring station located on the coast of the south-eastern part of the Baltic Sea (Kaliningrad Oblast, Russia).

description: The persistence of the first-order transition line in the phase diagram of mesoscopic Bi$_{2}$Sr$_{2}$CaCu$_{2}$O$_{8}$ vortex matter is detected down to a system size of less than hundred vortices. Precise and highly-sensitive to bulk currents AC magnetization techniques proved to be mandatory in order to obtain this information. The location of the vortex matter first-order transition lines are not altered by decreasing the sample size down to 20 $μ$m. Nevertheless, the onset of irreversible magnetization is affected by increasing the sample surface-to-volume ratio producing a noticeable enlargement of the irreversible vortex region above the second-peak transition.

Forest Carbon

description: Currently, significant attention is paid to environmental issues at all levels of management. Over the long history of human civilization, significant environmental damage has been accumulated, because not only large-scale industrial production, but also ordinary human life leads to the formation of a significant amount of harmful products that pollute the atmosphere, soil, and water spaces. The huge scale of the accumulated damage makes it necessary to resolve environmental issues at the highest level the level of international organizations and the leadership of individual states. At the same time, interest in the environmental agenda is connected both with the health of the population and with economic aspects, because in the near future in Europe, and then, possibly, in Russia, much more significant taxes and fines for non-environmentally friendly production and products will be introduced. Among a significant number of important environmental issues of our time, one of the most acute is the issue related to emissions of the so-called greenhouse gases (primarily carbon dioxide CO2 and methane, but also other gases) and the environmental damage resulting from this phenomenon.

description: We revisit the classical instability of closed strings in the Abelian Higgs model. The instability is expressed by a vanishing energy as the torus-like configuration shrinks to zero size. We treat the radius of the torus as a collective coordinate and demonstrate that a quantum mechanical treatment of this coordinate leads to a stabilization of the closed string at small radii.

description: Corruption remains a persistent challenge across nations, impeding socio-economic development and undermining public trust in governance institutions. In Nigeria, like many other countries, combating corruption has been a focal point for successive administrations. This study assessed the efficacy of whistleblowing systems in curbing corruption within the Ministries, Departments, and Agencies (MDAs) of the Southwest states of Nigeria. This research employed a survey research design utilizing self-administered questionnaires designed with a structured format, employing a 5-point Likert scale system The study focused on internal control and compliance officers within the Ministries, Departments, and Agencies (MDAs) of Southwest States, Nigeria, totaling 382 individuals. A census sampling approach was utilized, encompassing the entire population due to its manageable size. Data analysis encompassed both descriptive and inferential statistical techniques. Findings revealed that the components of whistleblowing systems, namely reporting channels, policies and procedures, and confidentiality and anonymity, had a statistically significant negative impact on the effectiveness of curbing corruption within the Ministries, Departments, and Agencies (MDAs) of the South-west states of Nigeria. This suggests that as reporting channels, policies and procedures, and confidentiality and anonymity within whistleblowing systems decrease, the effectiveness of curbing corruption diminishes. This underscores the crucial role of robust whistleblowing mechanisms in combating corruption and promoting transparency and accountability within government agencies. This study, therefore, recommends that Government should enhance reporting channels to facilitate the prompt and secure reporting of corrupt practices.

description: Efficient processing of crude oil in the oil refining industry develops the economy. To improve the oil products quality and increase its productivity, it is necessary to use minimal energy consumption. The release of harmful substances into the environment during technological processes of production has a certain negative impact on the ecological situation. The risks that may arise from all waste types in production objects are identified and controlled. According to the oil company's policy, reducing the impact of waste on the environment determines its recycling. In the technological processes course, environmental protection and safety personnel constantly monitor installation for gas safety, inspect the air and toxic environment, and ensure gas safety at work. When the raw material is heated to the required temperature in the furnace, the gas fuel supplied to the furnace creates a fire hazard. Technically, oil products coking makes it possible to cost-effectively and expediently increase and improve oil refining.

description: Observed galaxy clusters often exhibit X-ray morphologies suggestive of recent interaction with an infalling subcluster. Abell 3376 is a nearby (z=0.046) massive galaxy cluster whose bullet-shaped X-ray emission indicates that it may have undergone a recent collision. It displays a pair of Mpc-scale radio relics and its brightest cluster galaxy is located 970 h_70^-1 kpc away from the peak of X-ray emission, where the second brightest galaxy lies. We attempt to recover the dynamical history of Abell 3376. We perform a set of N-body adiabatic hydrodynamical simulations using the SPH code Gadget-2. These simulations of binary cluster collisions are aimed at exploring the parameter space of possible initial configurations. By attempting to match X-ray morphology, temperature, virial mass and X-ray luminosity, we set approximate constraints on some merger parameters. Our best models suggest a collision of clusters with mass ratio in the range 1/6-1/8, and having a subcluster with central gas density four times higher than that of the major cluster. Models with small impact parameter (b<150 kpc), if any, are preferred. We estimate that Abell 3376 is observed approximately 0.5 Gyr after core passage, and that the collision axis is inclined by i~40 degrees with respect to the plane of the sky. The infalling subcluster drives a supersonic shock wave that propagates at almost 2600 km/s, implying a Mach number as high as M~4; but we show how it would have been underestimated as M~3 due to projection effects.

description: We present deep Hubble Space Telescope/Wide Field and Planetary Camera 2 photometry of the young HD 97950 star cluster in the giant H {\sc ii} region NGC 3603. The data were obtained in 1997 and 2007 permitting us to derive membership based on proper motions of the stars. Our data are consistent with an age of 1 Myr for the HD 97950 cluster. A possible age spread, if present in the cluster, appears to be small. The global slope of the incompleteness-corrected mass function for member stars within 60$"$ is $\rm Γ=-0.88\pm0.15$, which is flatter than the value of a Salpeter slope of -1.35. The radially varying mass function shows pronounced mass segregation ranging from slopes of $-0.26 \pm 0.32$ in the inner $5"$ to $-0.94\pm 0.36$ in the outermost annulus ($40"$ -- $60"$). Stars more massive than 50 M$_{\odot}$ are found only in the cluster center. The $Λ$ minimum spanning tree technique confirms significant mass segregation down to 30 M$_{\odot}$. The dependence of $Λ$ on mass, i.e., that high-mass stars are more segregated than low mass stars, and the (weak) dependence of the velocity dispersion on stellar mass might imply that the mass segregation is dynamical in origin. While primordial segregation cannot be excluded, the properties of the mass segregation indicate that dynamical mass segregation may have been the dominant process for segregation of high-mass stars.
