description: Content-centric networking (CCN) has emerged as a dominant paradigm for future Internet architecture design due to its efficient support for content dissemination, which currently dominates Internet use. This dissertation shows how economic and social welfare analysis can be used to inform the design of a CCN architecture that provides network stakeholders with incentives to deploy and use. Firstly, the dissertation investigates the economic incentives of different stakeholders to deploy content-centric network Internet architectures and shows that network operators will fail to deploy sufficient storage infrastructure to support CCN without payment ows from publishers. However, the level of payment required differs for different network players, which gives them different competitive advantages in providing storage infrastructure and content delivery services. Secondly, it evaluates the social welfare implications of different storage deployment scenarios in a CCN-based architecture and identifies two deployments that maximize social welfare. In the first, edge networks provide the storage infrastructure through a transaction broker. In the second, edge networks pay third-parties an amount, equivalent to the realized benefits from a storage node, to deploy storage infrastructure in the network. All other deployment scenarios lead to a deadweight loss. Thirdly, the dissertation identifies content delivery functionalities that break in a CCN-based architecture and shows how these functionalities can be successfully replicated and enhanced by a careful design of the structure of routable content, content naming and the meta-information added to content. The proposed design supports several content delivery applications and can be easily extended to other networking principals. Finally, the dissertation identifies and discusses threats in the CCN content delivery model and proposes some mechanisms to address these threats. In addition, the dissertation identifies some policy implications of the CCN content delivery model and proposes some policy interventions that may lead to desirable deployment outcomes.
Very Small Strangelets

description: We study the stability of small strangelets by employing a simple model of strange matter as a gas of non-interacting fermions confined in a bag. We solve the Dirac equation and populate the energy levels of the bag one quark at a time. Our results show that for system parameters such that strange matter is unbound in bulk, there may still exist strangelets with $A<100$ that are stable and/or metastable. The lifetime of these strangelets may be too small to detect in current accelerator experiments, however.

Nathanaël, ou l’étrange art du déplacement : Le Carnet de Somme et son apatride traversée de frontières

Year: 2016

description: La pratique liminaire qui se donne à voir dans Carnets de Somme imagine le soi délesté d’assises traditionnelles nettement délimitées : genre, sexe, nominalisation, ainsi récit, donc trame narrative. Il s’agit d’une esthétique qui trace les contours mouvants de l’identité dite queer, faisant de ce fait allusion aux catégories genrées et génériques héritées de la tradition qui ont limité la conceptualisation du genre, qu’il soit littéraire ou sexuel. Cette esthétique-éthique suggère des ouvertures, des chemins de traverse qui ont à voir avec le refus viscéral de la fixité identitaire traditionnellement imposée, particulièrement délétère pour le féminin traditionnellement dévalué. Ce qui fait l’originalité de la posture de N., l'instance énonciative, donc, c’est l’élargissement de sa situation d’entre-deux à une prise de position qui à la fois englobe et déstabilise, comme on l’a vu, diverses frontières, afin de remettre en question rien de moins que les fondements de la représentation de l’être : sont atteintes les représentations du soi et de l’autre, et donc, nécessairement, des frontières des sexes, des assises de la langue (pronoms), des langues, du singulier et du collectif, et par là, de l’entrechoquement des langues-cultures.

description: Our repository is just over a year old and yet campus adoption is still an uphill battle. Even as repositories become more common and more popular, administration and faculty may still not understand the benefits of utilizing repositories and Open Access publication. Others may understand the concept of an IR but might be frustrated by the thought of it being another task added to their ever-increasing to-do list. The need to educate campus constituents on why the repository is important and how it can support their pursuit of tenure and promotion goals remains a challenge for most IR administrators. Education and outreach are crucial at this stage. Do you start with the faculty or the administration? Do you try to talk to faculty one-on-one or do you go to department meetings? Can you hold open sessions in the library or other central locations on campus? How can you leverage metrics and impact factors? This poster will address these questions and will provide a framework that you can take back to your campus and use to build rapport with faculty.

description: In countries with a moderate seismic hazard, the classical methods developed for strong motion prone countries to estimate the seismic behaviour and subsequent vulnerability of existing buildings are often inadequate and not financially realistic. The main goals of this paper are to show how the modal analysis can contribute to the understanding of the seismic building response and the good relevancy of a modal model based on ambient vibrations for estimating the structural deformation under moderate earthquakes. We describe the application of an enhanced modal analysis technique (Frequency Domain Decomposition) to process ambient vibration recordings taken at the Grenoble City Hall building (France). The frequencies of ambient vibrations are compared with those of weak earthquakes recorded by the French permanent accelerometric network (RAP) that was installed to monitor the building. The frequency variations of the building under moderate earthquakes are shown to be slight (~2%) and therefore ambient vibration frequencies are relevant over the elastic domain of the building. The modal parameters extracted from ambient vibrations are then used to determine the 1D lumped-mass model in order to reproduce the inter-storey drift under weak earthquakes and to fix a 3D numerical model that could be used for strong earthquakes. The correlation coefficients between data and synthetic motion are close to 80% and 90% in horizontal directions, for the 1D and 3D modelling, respectively.
Quantum Phase transition in the two dimensional ionic-Hubbard model

description: We employ the dynamical mean field approximation to study the effects of ionic potential ($Δ$) on the square lattice Hubbard model. At half-filling when the staggered potential ($Δ$) dominates the on-site Hubbard interaction ($U$), the system is in the band insulator phase. We find that competition between $U$ and $Δ$ can suppress the gap to zero and leading to an intermediate metallic region. At the large-$U$ limit, we identify a Mott insulator phase where the gap opens again and increases upon increasing the Hubbard interaction U. For $U\leq 9t$ and $Δ\approx 0$ the phase of the system is metallic, but for larger $U$ the system is in the Mott insulator phase.

description: Management of research data are becoming increasingly important especially as it is being required as a core requirement by journal publishers and funding agencies. Users' experience, as gathered from researchers in five federal universities of technology in Nigeria, showed that knowing the actual data to manage, how, when and where to manage it is quite difficult. This study aimed at developing a computer-based Research Data Management System (RDMS) that would guide researchers, who are actual data producers, on proper data management through their research life cycle so they would come up with a product (datasets) that repositories can accept and manage for future use and reuse. A mixed method approach of qualitative and quantitative instruments involving sequential exploratory strategy was adopted to understand the existing data workflow of researchers. The study also used evolutionary prototyping technique for the software development and the final prototype was subjected to technology acceptance testing using constructs of the unified theory of acceptance and use of technology. Findings revealed that use of the RDMS improved researchers' confidence in their own research process, better awareness on the benefits of repositories and also had a significant positive effect on their willingness to accept the open data principles.

description: Social media data are increasingly used in the social sciences. Archiving social media data is associated with a number of specific practical, legal, and ethical challenges that researchers and archivists need to address. In addition, the documentation of social media data also has its own requirements. This guide discusses these different challenges and provides suggestions for addressing them. Based on general considerations as well as examples of social media data that have been archived by CESSDA service providers (and how the identified challenges have been dealt with in those cases), the guide presents suggestions for metadata elements that need to be developed or extended for the proper documentation of social media data. Taking into account the various challenges in archiving social media data and how they may be addressed, the guide also presents practical recommendations for researchers working with social media data and the development of social media data collection tools with regard to the requirements for archiving them.

description: Non-linearities in the harmonic spectra of hadron-nucleus and nucleus-nucleus collisions provide evidence for the dynamical response to azimuthal spatial eccentricities. Here, we demonstrate within the framework of transport theory that even the mildest interaction correction to a picture of free-streaming particle distributions, namely the inclusion of one perturbatively weak interaction ("one-hit dynamics"), will generically give rise to all observed linear and non-linear structures. We further argue that transport theory naturally accounts within the range of its validity for realistic signal sizes of the linear and non-linear response coefficients observed in azimuthal momentum anisotropies with a large mean free path of the order of the system size in peripheral ($\sim 50 \%$ centrality) PbPb or central pPb collisions. The shear viscosity to entropy density ratio $η/s$ of such a transport theory is approximately an order of magnitude larger than that of an almost perfect fluid. The phenomenological success of transport simulations thus challenges the perfect fluid paradigm of ultra-relativistic nucleus-nucleus and hadron-nucleus collisions.

NREN-repository collaborations

description: The value of repositories increases significantly when they are connected through value added services. Research and education networks (RENs) provide connectivity for university communities and are also building so-called 'above-the-net' services such as secure network access and identity federation services (e.g. eduroam and eduGAIN). In Africa, the research and education networks are already playing a role to support open science and add value to African repositories and they are interested in increasing and expanding this role in collaboration with libraries. The LIBSENSE project is exploring collaborations between repositories and RENs in order to support the aims of both communities. As a first step, a workshop was organized by WACREN (West and Central Africa Research and Education Network) with support from COAR, OpenAIRE, EIFL and UbuntuNet Alliance in November 2018. The workshop brought together representatives from 17 African countries representing national repository networks and NRENs. This was the first in a series of meetings to develop a more cohesive strategy for strengthening and building repository networks in Africa through the adoption of value added services for repositories by NRENs.

description: We report in situ neutron background measurements at the Kuo-Sheng Reactor Neutrino Laboratory (KSNL) by a hybrid neutron detector (HND) with a data size of 33.8 days under identical shielding configurations as during the neutrino physics data taking. The HND consists of BC-501A liquid and BC-702 phosphor powder scintillation neutron detectors, which is sensitive to both fast and thermal neutrons, respectively. Neutron-induced events for the two channels are identified and differentiated by pulse shape analysis, such that background of both are simultaneously measured. The fast neutron fluxes are derived by an iterative unfolding algorithm. Neutron induced background in the germanium detector under the same fluxes, both due to cosmic-rays and ambient radioactivity, are derived and compared with the measurements. The results are valuable to background understanding of the neutrino data at the KSNL. In particular, neutron-induced background events due to ambient radioactivity as well as from reactor operation are negligible compared to intrinsic cosmogenic activity and ambient $γ$-activity. The detector concept and analysis procedures are applicable to neutron background characterization in similar rare-event experiments.

Study of DiMuon Rare Beauty Decays with ATLAS and CMS

Year: 2007
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: The LHC experiments will perform sensitive tests of physics beyond the Standard Model (BSM). The investigation of decays of beauty hadrons represents an alternative approach in addition to direct BSM searches. The ATLAS and CMS efforts concentrate on those B-decays that can be efficiently selected already at the first and second level trigger. The most favorable trigger signature will be for $B$-hadron decays with muons in the final state. Using this trigger, ATLAS and CMS will be able to accommodate unprecedentedly high statistics in the rare decay sector. These are purely dimuon decays, and families of semimuonic exclusive channels. Already with data corresponding to an integrated luminosity of \ensuremath{1 fb^{-1}}, the sensitivity in the dimuon channels will be comparable to present measurements (world average). The strategy is to carry on the dimuon channel program up to nominal LHC luminosity. In particular the \ensuremath{B_s \to μμ} signal with \ensuremath{\sim}5 sigma significance can be measured combining low luminosity \ensuremath{10^{33}cm^{-2} s^{-1}} samples with those of one year of LHC operation at a luminosity of \ensuremath{10^{34}cm^{-2} s^{-1}

description: The focus of this thesis is the study of the evolution of two models adopted in the context of phase separation and pattern formation, the Cahn-Hilliard model and the Swift-Hohenberg model. In the study of the Cahn-Hilliard model, the PDEs arising as the L2 and H-1 gradient flows in the higher dimensional setting n > 1 are studied, and estimates are provided on the evolution of solutions initiated close to configurations that globally or locally minimize the perimeter of the interface are provided. The results rely on a new regularity property of a local version of the well-known isoperimetric function. In the Swift-Hohenberg setting, the one dimensional model is considered, and the slow evolution of a particular class of solutions is established. In this context, existence and regularity of solutions in dimension n_< 3 are provided. In the last part of this thesis, two ongoing project and future research directions are presented.
Immobilized Double-Racemase Hydantoinase Process for L-Amino Acid Production

description: Protein immobilization is proving to be an environmentally friendly strategy for manufacturing biochemicals at high yields and low production costs. This work describes the optimization of the so-called “double-racemase hydantoinase process,” a system of four enzymes used to produce optically pure L-amino acids from a racemic mixture of hydantoins. Several methods have been used for L-amino acid production: protein hydrolysis, microbial fermentation, chemical synthesis, and enzymatic catalysis. The four proteins were immobilized separately, and, based on their specific activity, the optimal whole relation was determined. The first enzyme, D,L-hydantoinase, preferably hydrolyzes D-hydantoins from D,L-hydantoins to N-carbamoyl-D-amino acids. The remaining L-hydantoins are racemized by the second enzyme, hydantoin racemase, and continue supplying substrate d-hydantoins to the first enzyme. N-carbamoyl-D-amino acid is racemized in turn to N-carbamoyl-l-amino acid by the third enzyme, carbamoyl racemase. Finally, the N-carbamoyl-L-amino acid is transformed to L-amino acid by the fourth enzyme, L-carbamoylase. Therefore, the product of one enzyme is the substrate of another. Perfect coordination of the four activities is necessary to avoid the accumulation of reaction intermediates and to achieve an adequate rate for commercial purposes. The system has shown a broad pH optimum of 7–9, with a maximum activity at 8 and an optimal temperature of 60°C. Comparison of the immobilized system with the free protein system showed that the reaction velocity increased for the production of norvaline, norleucine, ABA, and homophenylalanine, while it decreased for L-valine and remained unchanged for L-methionine.

description: We present ALMA observations of the CO(6-5) and [CII] emission lines and the sub-millimeter continuum of the $z\sim6$ quasi-stellar object (QSO) SDSS J231038.88+185519.7. Compared to previous studies, we have analyzed a synthetic beam that is ten times smaller in angular size, we have achieved ten times better sensitivity in the CO(6-5) line, and two and half times better sensitivity in the [CII] line, enabling us to resolve the molecular gas emission. We obtain a size of the dense molecular gas of $2.9\pm0.5$ kpc, and of $1.4\pm0.2$ kpc for the 91.5 GHz dust continuum. By assuming that CO(6-5) is thermalized, and by adopting a CO--to--$H_2$ conversion factor $\rm α_{CO} = 0.8~ M_{\odot}~K^{-1}~ (km/s)^{-1} ~pc^{2}$, we infer a molecular gas mass of $\rm M(H_2)=(3.2 \pm0.2) \times 10^{10}\rm M_{\odot}$. Assuming that the observed CO velocity gradient is due to an inclined rotating disk, we derive a dynamical mass of $\rm M_{dyn}~sin^2(i) = (2.4\pm0.5) \times 10^{10}~ M_{\odot}$, which is a factor of approximately two smaller than the previously reported estimate based on [CII]. Regarding the central black hole, we provide a new estimate of the black hole mass based on the C~IV emission line detected in the X-SHOOTER/VLT spectrum: $\rm M_{BH}=(1.8\pm 0.5) \times 10^{9}~ M_{\odot}$. We find a molecular gas fraction of $\rm μ=M(H_2)/M^*\sim4.4$, where $\rm M^*\approx M_{dyn} - M(H_2)-M(BH)$. We derive a ratio $v_{rot}/σ\approx 1-2$ suggesting high gas turbulence, outflows/inflows and/or complex kinematics due to a merger event. We estimate a global Toomre parameter $Q\sim 0.2-0.5$, indicating likely cloud fragmentation. We compare, at the same angular resolution, the CO(6-5) and [CII] distributions, finding that dense molecular gas is more centrally concentrated with respect to [CII]. We find that the current BH growth rate is similar to that of its host galaxy.

description: Many health sciences disciplines have adopted team-based learning (TBL) as part of their education pedagogy, with studies showing increased classroom participation and learner satisfaction. However, it will be beneficial to explore the learning experiences of occupational therapy students in TBL using a mixed methods approach. In an undergraduate occupational therapy program, students undertook three clinical modules using TBL in years two and three. This study explored their perceptions and experiences of TBL. This was a mixed methods prospective cohort study, during which two cohorts of students from Academic Year (AY) 2016 and AY2017 completed the Team-Based Learning Student Assessment Instrument (TBL-SAI) at the end of their first (midway evaluation) and third clinical module (final evaluation). In addition, they completed a semi-structured survey to share their learning experience. One-hundred twenty-seven occupational therapy students from both cohorts had full data and their results showed higher than neutral for Accountability, Preference for TBL, and Student Satisfaction sub-scales and composite scores at midway and final survey. Collectively, there were no significant changes in TBL perceptions, and no significant relationships were found between TBL-SAI scores and module results. Within the AY2017 cohort, there was positive moderate association between Accountability sub-scale midway score and module results. Qualitative analysis produced four themes: 1) power of discussion; 2) time use; 3) changed learning process and outcome; and 4) tailoring aspects of TBL to enhance learning. Occupational therapy students’ scores in the TBL-SAI domains were higher than neutral at midway and final evaluation. TBL may be a suitable method to aid learning of clinical occupational therapy knowledge.

description: The rate of fatigue crack propagation of the 7050-T7651 aircraft material subjected to automatic shot peening machine and chromic acid anodizing (CAA) has been studied and compared with previous research results. Shot peening is a surface treatment by firing shot material so that the dimple is formed and residual stress occurs on the surface of the working specimen in order to increase resistance to fatigue failure. Al 7050-T7651 is made into specimens according to ASTM E647 standard treated with automatic shot peening machine (with steel shot material, 0.017 inch diameter, shot flow 30%, 3 bar pressure, Almen intensity 0.0082 A with 100 mm shooting range and 90° angle of shot) and CAA (operating standard) in surface treatment area of Indonesian Aerospace. The fatigue cracking test with a load of about 200 kg, with a stress ratio of R = 0.1. The results of the fatigue crack growth test resulted in the constant of Paris A=3.654 × 10-9 and n = 1.67, indicating that the automatic shot peening machine and chromic acid anodizing treatment decreased the fatigue life and increased the fatigue crack growth rate compared to the automatic shot peening machine, manual machine with or without CAA, and without treatment.

description: The total mass of a distant star cluster is often derived from the virial theorem, using line-of-sight velocity dispersion measurements and half-light radii, under the implicit assumption that all stars are single (although it is known that most stars form part of binary systems). The components of binary stars exhibit orbital motion, which increases the measured velocity dispersion, resulting in a dynamical mass overestimation. In this article we quantify the effect of neglecting the binary population on the derivation of the dynamical mass of a star cluster. We find that the presence of binaries plays an important role for clusters with total mass M < 10^5 Msun; the dynamical mass can be significantly overestimated (by a factor of two or more). For the more massive clusters, with Mcl > 10^5 Msun, binaries do not affect the dynamical mass estimation significantly, provided that the cluster is significantly compact (half-mass radius < 5 pc).

description: We develop a superfield formalism for N=4 superconformal two-dimensional field theory. A list is presented of minimal free superfields, i.e. of multiplets containing four bosons and four fermions. We show that the super-Poincaré algebra of the six-dimensional superstring in the light-cone gauge is essentially equivalent to a local N=4 superconformal symmetry, and outline the construction of octonionic superconformal field theory.

description: This paper is devoted to investigate the cold plasma wave properties outside the event horizon of the Schwarzschild planar analogue. The dispersion relations are obtained from the corresponding Fourier analyzed equations for non-rotating and rotating, non-magnetized and magnetized backgrounds. These dispersion relations provide complex wave numbers. The wave numbers are shown in graphs to discuss the nature and behavior of waves and the properties of plasma lying in the vicinity of the Schwarzschild event horizon.

description: This work is concerned with optimal control problems where the objective functional consists of a tracking-type functional and an additional "multibang" regularization functional that promotes optimal control taking values from a given discrete set pointwise almost everywhere. Under a regularity condition on the set where these discrete values are attained, error estimates for the Moreau--Yosida approximation (which allows its solution by a semismooth Newton method) and the discretization of the problem are derived. Numerical results support the theoretical findings.

description: The behavior of isothermal plasma waves has been analyzed near the Schwarzschild horizon. We consider a non-rotating background with non-magnetized and magnetized plasmas. The general relativistic magnetohydrodynamical equations for the Schwarzschild planar analogue spacetime with an isothermal state of the plasma are formulated. The perturbed form of these equations is linearized and Fourier analyzed by introducing simple harmonic waves. The determinant of these equations in each case leads to a complex dispersion relation, which gives complex values of the wave number. This has been used to discuss the nature of the waves and their characteristics near the horizon.

description: We relate the structure factor $S(\mathbf{k} \to \mathbf{0})$ in a system of jammed hard spheres of number density $ρ$ to its complexity per particle $Σ(ρ)$ by the formula $S(\mathbf{k} \to \mathbf{0})=-1/ [ρ^2Σ''(ρ)+2ρΣ'(ρ)]$. We have verified this formula for the case of jammed disks in a narrow channel, for which it is possible to find $Σ(ρ)$ and $S(\mathbf{k})$ analytically. Hyperuniformity, which is the vanishing of $S(\mathbf{k} \to \mathbf{0})$, will therefore not occur if the complexity is nonzero. An example is given of a jammed state of hard disks in a narrow channel which is hyperuniform when generated by dynamical rules that produce a non-extensive complexity.

description: In recent years there has been a rapid increase in the number of wireless devices for both commercial and defense applications. Such unprecedented demand has increased device cost and complexity and also added a strain on the spectrum utilization of wireless communication systems. This thesis addresses these issues, from an antenna system perspective, by developing new techniques to dynamically optimize adaptive beamforming arrays for improved anti-jamming and reliability. Available frequency spectrum is a scarce resource, and therefor e increased interference will occur as the wireless spectrum saturates. To mitig ate unintentional interference, or intentional interference from a jamming source, antenna arrays are used to focus electromagnetic energy on a signal of interest while simultaneously minimizing radio frequency energy in directions of interfering signals. The reliability of such arrays, especially in commercial satellite and defense applications, can be addressed by hardware redundancy, but at the expense of increased volume, mass as well as component and design cost. This thesis proposes the development of new models and optimization algorithms to dynamically adapt beamforming arrays to mitigate interference and increase hardware reliability. The contributions of this research are as follows. First, analytical models are developed and experimental results show that small antenna arrays can thwart interference using dynamically applied stochastic algorithms. This type of insitu optimization, with an algorithm dynamically optimizing a beamformer to thwart interference sources with unknown positions, inside of an anechoic chamber has not been done before to our knowledge. Second, it is shown that these algorithms can recover from hardware failures and localized faults in the array. Experiments were performed with a proof-of-concept four-antenna array. This is the first hardware demonstration showing an antenna array with live hardware fault recovery that is adapted by stochastic algorithms in an anechoic chamber. We also compare multiple stochastic algorithms in performing both anti-jamming and hardware fault recovery. Third, we show that stochastic algorithms can be used to continuously track and mitigate interfering signals that continuously move in an additive white Gaussian noise wireless channel.

description: Joint models for longitudinal and time-to-event data are commonly used in longitudinal studies to forecast disease trajectories over time. While there are many advantages to joint modeling, the standard forms suffer from limitations that arise from a fixed model specification, and computational difficulties when applied to high-dimensional datasets. In this paper, we propose a deep learning approach to address these limitations, enhancing existing methods with the inherent flexibility and scalability of deep neural networks, while retaining the benefits of joint modeling. Using longitudinal data from a real-world medical dataset, we demonstrate improvements in performance and scalability, as well as robustness in the presence of irregularly sampled data.

description: In this work, microfluidic and millifluidic droplets are utilized to study and control complex fluid behavior with high composition resolution. Different techniques are used on two length scales to create unique approaches towards the same goal of merging droplet-based experiments with classical colloidal characterization experiments. First, a microfluidic dehydrating droplet device is characterized and a procedure established by concentrating a phase separating organic-inorganic system on chip and using geometric calculations to determine composition. The device is then expanded to a more complex, particle-polymer system to investigate suspension stability and interparticle behavior. A model system containing silica particles and PEO polymer is found to transition from a bridging flocculation mechanism to polymer-coated particle jamming based on the mass ratio of polymer to particle. Lastly, a phase separating particle-polymer system consisting of polystyrene particles and hydroxyethyl cellulose is concentrated on-chip. Interparticle interactions are controlled by varying particle size, polymer size, and polymer type and the effects on phase behavior are examined. Droplet experiments are scaled-up to millifluidic droplets and concentration gradients are used to produce high composition resolution in place of time, used in the dehydrating microfluidic experiments. A novel, millifluidic containment device is created to study aggregation and sedimentation in droplets containing carbon black and OLOA surfactant suspended in dodecane. A slow increase in stabilization behavior is observed as opposed to the previously observed sharp “on-off” effect. The droplet production technique is then improved to achieve more complex composition paths and the device is expanded for a small angle neutron scattering (SANS) application. SANS is performed on flowing droplets with varying concentration to map interparticle interactions and phase behavior of complex particulate systems. Feasibility of device is demonstrated and preliminary model systems of silica particles and polymer, salt, and surfactant are analyzed and characterized.

description: A comparative study on different bimetallic nanocatalysts prepared from microemulsion using a one-pot method has been carried out. The analysis of experimental observations, complemented by simulation studies, provides detailed insight into the factors affecting nanoparticle architecture: 1.- The metal segregation in a bimetallic nanocatalysts is the result of the combination of three main kinetic parameters: the reduction rate of metal precursors (related to reduction standard potentials), the material intermicellar exchange rate (determined by microemulsion composition) and the metal precursors concentration. 2.- A minimum difference between the reduction standard potentials of the two metals of 0.20 V is needed to obtain a core-shell structure. For values De° smaller than 0.20 V the obtaining of alloys cannot be avoided, neither by changing the microemulsion nor by increasing metal concentration. 3.- As a rule, the higher the film flexibility around the micelles, the higher the degree of mixture in the nanocatalyst. 4.- A minimum concentration of metal precursors is required to get a core-shell structure. This minimum concentration depends on the microemulsion flexibility and on the difference in reduction rates.
