description: Speech is the fundamental means of communication between humans. The advent of AI and sophisticated speech technologies have led to the rapid proliferation of human-to-computer-based interactions, fueled primarily by Automatic Speech Recognition (ASR) systems. ASR systems normally take human speech in the form of audio and convert it into words, but for some users, it cannot decode the speech, and any output text is filled with errors that are incomprehensible to the human reader. These systems do not work equally for everyone and actually hinder the productivity of some users. In this paper, we present research that addresses ASR biases against gender, race, and the sick and disabled, while exploring studies that propose ASR debiasing techniques for mitigating these discriminations. We also discuss techniques for designing a more accessible and inclusive ASR technology. For each approach surveyed, we also provide a summary of the investigation and methods applied, the ASR systems and corpora used, and the research findings, and highlight their strengths and/or weaknesses. Finally, we propose future opportunities for Natural Language Processing researchers to explore in the next level creation of ASR technologies.

description: We discuss a family of time-reversible, scale-invariant diffusions with singular coefficients. In analogy with the standard Gaussian theory, a corresponding family of generalized characteristic functions provides a useful tool for proving limit theorems resulting in non-Gaussian, scale-invariant diffusions. We apply the generalized characteristic functions in combination with a martingale construction to prove a simple invariance principle starting from a spatially inhomogeneous nearest-neighbor random walk.

description: Recent progress in high-resolution transmission spectroscopy has offered new avenues in which to characterise the atmospheres of transiting exoplanets. High-resolution cross-correlation spectroscopy allows for the unambiguous detection of molecules/atoms. It has also been used to map both atmospheric dynamics and longitudinal variations in the abundance of species across the morning and evening limbs. We present multiple VLT/ESPRESSO observations of the ultra-hot Jupiter WASP-121b, from which we constrain relative abundances of various neutral metals consistently across all observations, whilst accounting for the distortion of the exoplanet's signal caused by traditional data processing techniques. We also constrain planetary orbital velocities and $T$-$P$ profiles. We compare our abundance constraints with previous constraints using VLT/UVES transmission spectroscopy of WASP-121b, and find our results to be consistent between observations, and also in agreement with stellar values for species previously detected in the atmosphere of WASP-121b. Our retrieval framework can also be used to identify potential exospheric species, resulting in extended absorption features beyond the transit equivalent Roche limit of WASP-121b ($R_{\rm eqRL}$ $\sim$ 1.3 $R_{\rm p}$). H$α$, Fe II, and Ca II were found to extend to high altitudes ($1.54\pm0.04$ $R_{\rm p}$, $1.17\pm0.01$ $R_{\rm p}$, and $2.52\pm0.34$ $R_{\rm p}$, respectively), which are broadly consistent with literature values. The consistency of our constraints across multiple high-resolution observations is a strong validation of our model filtering and retrieval framework, as well as the stability of the atmosphere over the timescales of months/years, and could allow for planet formation processes to be inferred from future ground-based observations of exoplanetary atmospheres.

description: Motivated by applications requiring quantile estimates for very small probabilities of exceedance, this article addresses estimation of high quantiles for probabilities bounded by powers of sample size with exponents below -1. As regularity assumption, an alternative to the Generalised Pareto tail limit is explored for this purpose. Motivation for the alternative regularity assumption is provided, and it is shown to be equivalent to a limit relation for the logarithm of survival function, the log-GW tail limit, which generalises the GW (Generalised Weibull) tail limit, a generalisation of the Weibull tail limit. The domain of attraction is described, and convergence results are presented for quantile approximation and for a simple quantile estimator based on the log-GW tail. Simulations are presented, and advantages and limitations of log-GW-based estimation of high quantiles are indicated.

description: We present and analyze a series of synthetic galaxy survey fields based on the IllustrisTNG Simulation suite. With the Illustris public data release and JupyterLab service, we generated a set of twelve lightcone catalogs covering areas from 5 to 365 square arcminutes, similar to several JWST Cycle 1 programs, including JADES, CEERS, PRIMER, and NGDEEP. From these catalogs, we queried the public API to generate simple mock images in a series of broadband filters used by JWST-NIRCam and the Hubble Space Telescope cameras. This procedure generates wide-area simulated mosaic images that can support investigating the predicted evolution of galaxies alongside real data. Using these mocks, we demonstrate a few simple science cases, including morphological evolution and close pair selection. We publicly release the catalogs and mock images through MAST, along with the code used to generate these projects, so that the astrophysics community can make use of these products in their scientific analyses of JWST deep field observations.

description: In two-mode interferometry, for a given total photon number $N$, entangled Fock state superpositions of the form $(|N-m\rangle_a|m\rangle_b+e^{i (N-2m)ϕ}|m\rangle_a|N-m\rangle_b)/\sqrt{2}$ have been considered for phase estimation. Indeed all such states are maximally mode-entangled and violate a Clauser-Horne-Shimony-Holt (CHSH) inequality. However, they differ in their optimal phase estimation capabilities as given by their quantum Fisher informations. The quantum Fisher information is the largest for the $N00N$ state $(|N\rangle_a|0\rangle_b+e^{i Nϕ}|0\rangle_a|N\rangle_b)/\sqrt{2}$ and decreases for the other states with decreasing photon number difference between the two modes. We ask the question whether for any particular Clauser-Horne (CH) (or CHSH) inequality, the maximal values of the CH (or the CHSH) functional for the states of the above type follow the same trend as their quantum Fisher informations, while also violating the classical bound whenever the states are capable of sub-shot-noise phase estimation, so that the violation can be used to quantify sub-shot-noise sensitivity. We explore CH and CHSH inequalities in a homodyne setup. Our results show that the amount of violation in those nonlocality tests may not be used to quantify sub-shot-noise sensitivity of the above states.

description: We consider a class of wave-Schroedinger systems with a Zakharov-Schulman type coupling. This class of systems is indexed by a parameter gamma which measures the strength of the null form in the nonlinearity of the wave equation. The case gamma = 1 corresponds to the well-known Zakharov system, while the case gamma = -1 corresponds to the Yukawa system. Here we show that sufficiently smooth and localized Cauchy data lead to pointwise decaying global solutions which scatter, for any gamma in (0,1].

description: Research software is a critical component of computational research. Thus, being able to discover, understand and adequately utilize software is essential. Associated metadata to research software enables discovering, understanding and utilizing software. However, metadata tends to be sparse and frequently inconsistent across different resources.

 The ELIXIR Tools Ecosystem (TEc) aims to act as a proxy to maintain and preserve high-quality metadata for describing research software. To make this possible, the TEc works closely with heterogeneous metadata resources. These resources often have different objectives, user communities and technical implementations. The goals of the TEc are to bring metadata together, facilitate integration, curation, and re-usability by the contributors and anyone willing to consume the metadata produced in this context.

 The TEc currently focuses primarily on the Services associated with the ELIXIR Tools Platform, that gather, curate, maintain and consume high-quality metadata associated with research software. Specifically, the Tools Ecosystem includes bio.tools, BIII.eu, Biocontainers, OpenEBench, Galaxy, and WorkflowHub, and EDAM as the ontology for describing research software metadata. Additionally, multiple resources driven by other infrastructures and communities are included in our efforts, such as Bioconda and Debian (Med).

 As an open source project bringing together under the same umbrella different projects and initiatives, the TEc follows the guidelines, recommendations and standards put forward by ELIXIR, and other community-driven initiatives in the scope of open science.

description: Fragmentation of rotating gaseous systems via gravitational instability is believed to be a crucial mechanism in several astrophysical processes, such as formation of planets in protostellar discs, of molecular clouds in galactic discs, and of stars in molecular clouds. Gravitational instability is fairly well understood for infinitesimally thin discs. However, the thin-disc approximation is not justified in many cases, and it is of general interest to study the gravitational instability of rotating fluids with different degrees of rotation support and stratification. We derive dispersion relations for axisymmetric perturbations, which can be used to study the local gravitational stability at any point of a rotating axisymmetric gaseous system with either barotropic or baroclinic distribution. 3D stability criteria are obtained, which generalize previous results and can be used to determine whether and where a rotating system of given 3D structure is prone to clump formation. For a vertically stratified gaseous disc of thickness $h_z$ (defined as containing $\approx$70% of the mass per unit surface), a sufficient condition for local gravitational instability is $Q_{\rm 3D}\equiv\left(\sqrt{κ^2+ν^2}+c_s h_z^{-1}\right)/{\sqrt{4πGρ}}<1$, where $ρ$ is the gas volume density, $κ$ the epicycle frequency, $c_s$ the sound speed, and $ν^2\equivρ_z p_z/ρ^2$, where $ρ_z$ and $p_z$ are the vertical gradients of, respectively, gas density and pressure. The combined stabilizing effects of rotation ($κ^2$) and stratification ($ν^2$) are apparent. In unstable discs, the conditions for instability are typically met close to the midplane, where the perturbations that are expected to grow have characteristic radial extent of a few $h_z$.

description: NeLS is an infrastructure provided by ELIXIR Norway that provides an assembly of data management tools for planning, processing, analysing, and sharing of data throughout the RDM life cycle. Researchers in Norway and their collaborators can access the infrastructure and tools, apply for storage quotas and receive support from the national bioinformatics helpdesk.
 The NeLS Data Management tool assembly offers support with data management planning using the Data Stewardship Wizard with tailored guidance for the national framework, We have further connected the web-based metadata management platform FAIRDOM SEEK with our 3-layer tiered storage system. NeLS provides also access to a national instance of Galaxy with ~2000 tools for processing and analyzing data. We are furthermore working on tools for deposition of data stored in NeLS into the ELIXIR Deposition Databases and national archives.
 All tools are accessible with the national SAML 2.0/openID based identification solution FEIDE and LS Login.
 Overall, NeLS provides a comprehensive data management infrastructure that researchers in Norway can leverage to streamline their data management workflows.

description: Effective management and analysis of genotypic, phenotypic, and environmental data generated by plant breeding initiatives are crucial for informed decision-making. However, many existing repository solutions may not meet the specific project requirements, forcing individuals to rely on Excel files for data storage, despite Excel not being an ideal option. Using such data files may lead to errors and complicated processing. To prevent such issues, we have developed an approach that utilizes Excel templates to store project data. These templates adhere to existing standards such as MCPD or MIAPPE but are also flexible enough to incorporate project-specific information. Additionally, we have developed a validation process using the Frictionless library, which was implemented in the EU AGENT project, to help data providers meet all template requirements.

 Our approach links accessions from a project to a shared database of known accessions with passport data using a unique identifier. This accession database is also stored in a standardized and Frictionless validated Excel file. This process of linking accessions from a project file to this database can often largely be automated. Validated and linked Excel files can be seamlessly imported into an existing repository system such as Germinate, which also offers a BrAPI endpoint for accessing and analysing the data. This enables easy updating of published data whenever new project data becomes available.

 Overall, our approach provides a straightforward yet effective way of managing data from different plant breeding experiments and projects while adhering to the FAIR principles.
Evolution of grain size distribution with enhanced abundance of small carbonaceous grains in galactic environments

Publisher: name: arXiv
Year: 2022
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: We propose an updated dust evolution model that focuses on the grain size distribution in a galaxy. We treat the galaxy as a one-zone object and include five main processes (stellar dust production, dust destruction in supernova shocks, grain growth by accretion and coagulation, and grain disruption by shattering). In this paper, we improve the predictions related to small carbonaceous grains, which are responsible for the 2175 Å bump in the extinction curve and the polycyclic aromatic hydrocarbon (PAH) emission features in the dust emission spectral energy distribution (SED), both of which were underpredicted in our previous model. In the new model, we hypothesize that small carbonaceous grains are not involved in interstellar processing. This avoids small carbonaceous grains being lost by coagulation. We find that this hypothetical model shows a much better match to the Milky Way (MW) extinction curve and dust emission SED than the previous one. The following two additional modifications further make the fit to the MW dust emission SED better: (i) The chemical enrichment model is adjusted to give a nearly solar metallicity in the present epoch, and the fraction of metals available for dust growth is limited to half. (ii) Aromatization for small carbonaceous grains is efficient, so that the aromatic fraction is unity at grain radii $\lesssim 20$ Å. As a consequence of our modelling, we succeed in obtaining a dust evolution model that explains the MW extinction curve and dust emission SED at the same time.

description: Given a group $G$ and an abelian $C^*$-algebra $\mathfrak{A}$, the antihomomorphisms $Θ\colon G\rightarrow \mathrm{Aut}(\mathfrak{A})$ are in one-to-one with those left actions $Φ\colon G\times \mathrm{Spec}(\mathfrak{A})\rightarrow \mathrm{Spec}(\mathfrak{A})$ whose translation maps $Φ_g$ are continuous; whereby continuities of $Θ$ and $Φ$ turn out to be equivalent if $\mathfrak{A}$ is unital. In particular, a left action $ϕ\colon G \times X\rightarrow X$ can be uniquely extended to the spectrum of a $C^*$-subalgebra $\mathfrak{A}$ of the bounded functions on $X$ if $ϕ_g^*(\mathfrak{A})\subseteq \mathfrak{A}$ holds for each $g\in G$. In the present paper, we apply this to the framework of loop quantum gravity. We show that, on the level of the configuration spaces, quantization and reduction in general do not commute, i.e., that the symmetry-reduced quantum configuration space is (strictly) larger than the quantized configuration space of the reduced classical theory. Here, the quantum-reduced space has the advantage to be completely characterized by a simple algebraic relation, whereby the quantized reduced classical space is usually hard to compute.

X-ray from Outflow-Cloud Interaction and Its Application in Tidal Disruption Events

Year: 2022
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: Tidal disruption events (TDEs) may occur in supermassive black holes (SMBHs) surrounded by clouds. TDEs can generate ultrafast and large opening-angle outflow with a velocity of $\sim$ 0.01--0.2 c, which will collide with clouds with time lags depending on outflow velocity and cloud distances. Since the fraction of the outflow energy transferred into cloud's radiation is anti-correlated with the cloud density, high density clouds was thought to be inefficient in generating radiation. In this work, we studied the radiation from the outflow-cloud interactions for high density clouds, and found that thermal conduction plays crucial roles in increasing the cloud's radiation. Up to 10\% of the bow shock energy can be transferred into clouds and gives rise to X-ray emission with equivalent temperature of $10^{5-6}$ Kelvins due to the cooling catastrophe. The inverse Compton scattering of TDE UV/optical photons by relativistic electrons at bow shock generates power-law X-ray spectra with photon indices $Γ\sim 2-3$. This mechanism may account for some TDE candidates with delayed X-ray emission, and can be examined by delayed radio and gamma-ray emissions.

description: This thesis presents a close analysis of Ashton Raggatt McDougall's addition to the Shrine of Remembrance to examine opportunities for contemporary architecture to help shape the narratives of history, belonging and identity that make up public space. It draws on the theoretical concept of intertextuality, borrowed from literary theory and brought to architecture, to explore ways in which both contemporary architecture and visitors can have agency around what meaning and representation can be extracted from heritage spaces like memorials. It argues that we can engage with important architectural spaces in meaningful and respectful ways - calling this 'creative preservation'.

description: Building on recent results regarding symmetric probabilistic constructions of countable structures, we provide a method for constructing probability measures, concentrated on certain classes of countably infinite structures, that are invariant under all permutations of the underlying set that fix all constants. These measures are constructed from inverse limits of measures on certain finite structures. We use this construction to obtain invariant probability measures concentrated on the classes of countable models of certain first-order theories, including measures that do not assign positive measure to the isomorphism class of any single model. We also characterize those transitive Borel G-spaces admitting a G-invariant probability measure, when G is an arbitrary countable product of symmetric groups on a countable set.

As a fundamental application we establish a gluing formula for refined analytic torsion on connected components of the complex representation space which contain a unitary point. Finally we provide a new proof of Bruening-Ma gluing formula for the Ray-Singer torsion associated to a non-Hermitian connection. Our proof is quite different from the one given by Bruening and Ma and uses a temporal gauge transformation.

disk diffusion

description: Routine antimicrobial susceptibility testing (AST) is a prerequisite for understanding and treating Clostridioides (formerly Clostridium,
 C.) difficile infections (CDI) which cause thousands of fatal cases in the EU each year. The disc diffusion (DD) methodology proved to be a suitable and convenient alternative to the current gold standard, the agar dilution (AD) for moxifloxacin, metronidazole and
 vancomycin [1]. Yet, DD has major drawbacks regarding reproducibility and the unknown influence of anaerobic conditions on the test result. The aim of this study within the One Health European Joint Programme project IMPART (IMproving Phenotypic Antimicrobial Resistance Testing) project is to optimize and propose a protocol for a robust DD method for C. difficile for a broader range of antimicrobials and to find out, under which conditions and cut-off values a resistance determination is reliable.

Exact compression of waveform data
Creators: name: Fox, Simon
Publisher: name: Monash University
Year: 2018
Subjects: Uncategorized

description: This thesis studies techniques for lossless compression of one dimensional waveform data. Linear predictive coding is investigated as a means of pre-processing the data in order to reduce waveform redundancy. Much of the previous work in computing linear predictors is based on the least-squares criterion where predictor coefficients are chosen to minimise the squared sum of resulting prediction errors. Observing that the distribution of prediction error data is well approximated by the Laplacian distribution it is expected that the least-absolute-deviations criterion will be more effective in modelling this data. In the context of compression the optimal predictor is one which minimised the entropy of the resulting prediction error distribution. The IRLS algorithm is used to compute predictors based on the least-entropy and least-absolute-deviations criteria. Results are presented to show that the least-squares criterion is in general not optimal and often performs poorly in the presence of outliers in the data. The least –absolute-deviations criterion is shown to be very close to optima in most cases. It is shown how the IRLS algorithm may also be used to compute predictors which minimise the entropy of quantized prediction errors in the context of lossy compression. […]

K. Saito proved the converse. The same result is true for complete intersections, but is much harder. For a Gorenstein surface singularity $(V,0)$, the difference $μ- τ$ can be defined whether or not $V$ is smoothable; it was proved in [23] that it is non-negative, and equal to 0 iff $(V,0)$ is quasi-homogeneous. We conjecture a similar result for non-Gorenstein surface singularities. Here, $μ- τ$ must be modified so that it is independent of any smoothing. This expression, involving cohomology of exterior powers of the bundle of logarithmic derivations on the minimal good resolution, is conjecturally non-negative, and equal to 0 iff one has quasi-homogeneity. We prove the "if" part; identify special cases where the conjecture is particularly interesting; verify it in some non-trivial cases; and prove it for a $\Q$Gorenstein smoothing when the index one cover is a hypersurface. This conjecture is of interest regarding the classification of surface singularities with rational homology disk smoothings, as in [1], [18], [24].

description: For any root system and any commutative ring we give a relatively simple presentation of a group related to its Steinberg group St. This includes the case of infinite root systems used in Kac-Moody theory, for which the Steinberg group was defined by Tits and Morita-Rehmann. In most cases our group equals St, giving a presentation with many advantages over the usual presentation of St. This equality holds for all spherical root systems, all irreducible affine root systems of rank>2, and all 3-spherical root systems. When the coefficient ring satisfies a minor condition, the last condition can be relaxed to 2-sphericity. Our presentation is defined in terms of the Dynkin diagram rather than the full root system. It is concrete, with no implicit coefficients or signs. It makes manifest the exceptional diagram automorphisms in characteristics 2 and 3, and their generalizations to Kac-Moody groups. And it is a Curtis-Tits style presentation: it is the direct limit of the groups coming from 1- and 2-node subdiagrams of the Dynkin diagram. Over non-fields this description as a direct limit is new and surprising. Our main application is that many Steinberg and Kac-Moody groups over finitely-generated rings are finitely presented.

The Gilbert damping plays an important role for understanding the switching behavior of perpendicular magnetic random-access memory (MRAM) cells. Damping measurements are typically made on full films of the free layer materials rather than on finished devices. It is to be expected that the damping is different between the device and the film level measurements [1,2,3]. Here we report on device level damping measurements using spin-torque driven ferromagnetic resonance. For all free layer materials investigated, we find that the extracted damping increases with decreasing device size and is higher than the respective film level values (Fig. 1). It is worked out that thermal agitation disturbs the resonance and causes an increase of the apparent damping. The effect is modeled by Langevin dynamics and good agreement with a variety of experimental details is obtained. An illustration of the thermal effect is shown in Fig. 2. For MRAM sizes bigger than about 55nm, the thermal agitation effect becomes negligible. Beyond the increase caused by thermal agitation, we believe that the device level damping is still somewhat higher than the film-level dampingReferences: [1] O. Ozatay et al., Nat.

Generic emergence of classical features in quantum Darwinism

description: Quantum Darwinism explains the emergence of classical reality from the underlying quantum reality by the fact that a quantum system is observed indirectly, by looking at parts of its environment, so that only specific information about the system that is redundantly proliferated to many parts of the environment becomes accessible and objective. However it is not clear under what conditions this mechanism holds true. Here we rigorously prove that the emergence of classicality is a general feature of any quantum dynamics: observers who acquire information about a quantum system indirectly have access at most to classical information about one and the same measurement of the quantum system; moreover, if such information is available to many observers, they necessarily agree. Remarkably, our analysis goes beyond the system-environment categorization. We also provide a full characterization of the so-called quantum discord in terms of local redistribution of correlations.

Variability In A Low-Mass AGN: Oscillation Or Eruption?

description: Following the discovery of a new class of X-ray variability seen in four galaxies, dubbed Quasi-Periodic Eruptions (QPEs), we reconsider the variability seen in the low-mass AGN 2XMM J123103.2+110648 to ascertain whether it should be considered the fifth QPE host galaxy. We apply the autocorrelation function to two archival XMM-Newton observations to determine characteristic timescales for variability of $\sim$ 13.52 ks and $\sim$ 14.35 ks. The modelling of lightcurves, both folded at these timescales and unfolded, indicates that a Gaussian model is preferable over a sinusoidal model, with average durations for the bright phases of 6.17 ks and 7.69 ks. In a broad 0.2-1.0 keV band the average amplitude of the bright phases was found to be 2.86 and 8.56 times the quiescent count rate. The pattern of variability seen in 2XMM J123103.2+110648 cannot be definitively declared as a series of Quasi-Periodic Eruptions. Instead, this suggests there may be a continuum of quasi-periodic variability ranging from eruptions to oscillations being caused by a single mechanism. This offers the possibility of finding further sources that continue to bridge the gap between QPEs and Quasi-Periodic Oscillations. A targeted analysis of 47 observations of 11 other low-mass AGN $(log(M_{BH}) \lesssim 6)$ found no evidence of QPE or QPO-like behaviour in a sample of other similar mass objects.

description: We present the analysis of a spectroscopic secondary eclipse of the hottest transiting exoplanet detected to date, KELT-9b, obtained with the Wide Field Camera 3 aboard the Hubble Space Telescope. We complement these data with literature information on stellar pulsations and Spitzer/Infrared Array Camera and Transiting Exoplanet Survey Satellite eclipse depths of this target to obtain a broadband thermal emission spectrum. Our extracted spectrum exhibits a clear turnoff at 1.4$μ$m. This points to H$^{-}$ bound-free opacities shaping the spectrum. To interpret the spectrum, we perform grid retrievals of self-consistent 1D equilibrium chemistry forward models, varying the composition and energy budget. The model with solar metallicity and C/O ratio provides a poor fit because the H$^{-}$ signal is stronger than expected, requiring an excess of electrons. This pushes our retrievals toward high atmospheric metallicities ($[M/H]=1.98^{+0.19}_{-0.21}$) and a C/O ratio that is subsolar by 2.4$σ$. We question the viability of forming such a high-metallicity planet, and therefore provide other scenarios to increase the electron density in this atmosphere. We also look at an alternative model in which we quench TiO and VO. This fit results in an atmosphere with a slightly subsolar metallicity and subsolar C/O ratio ($[M/H]=-0.22^{+0.17}_{-0.13}$, log(C/O)$=-0.34^{+0.19}_{-0.34}$). However, the required TiO abundances are disputed by recent high-resolution measurements of the same planet.

description: Define $\|n\|$ to be the complexity of $n$, the smallest number of ones needed to write $n$ using an arbitrary combination of addition and multiplication. John Selfridge showed that $\|n\| \ge 3\log_3 n$ for all $n$. Define the defect of $n$, denoted $δ(n)$, to be $\|n\| - 3\log_3 n$. In this paper, we consider the set $\mathscr{D} := \{δ(n): n \ge 1 \}$ of all defects. We show that as a subset of the real numbers, the set $\mathscr{D}$ is well-ordered, of order type $ω^ω$. More specifically, for $k\ge 1$ an integer, $\mathscr{D}\cap[0,k)$ has order type $ω^k$. We also consider some other sets related to $\mathscr{D}$, and show that these too are well-ordered and have order type $ω^ω$.

ELECTROCHEMICAL DETECTION SYSTEM FOR THIOCHOLINE USING CLUSTER-ASSEMBLED ZIRCONIA MODIFIED GOLD ELECTRODES

description: In this work we report about a transducer based on gold electrodes modified with cluster-assembled zirconia nanostructured films produced by Supersonic Cluster Beam Deposition (SCBD) that can be implemented in a portable detection system for organophosphate compound pesticides based on electrochemical detection of Thiocholine. By using SCBD it is possible to quantitatively control the surface morphology, surface pores and surface specific area, as well as the roughness that depends on the film thickness. The nanoscale surface morphology and the nanopores have a substantial role in the processes involving the interaction of biological entities with nanostructured surfaces [1]. Here we show that cluster-assembled zirconia nanostructured films produced with SCBD are an effective promoter for electrochemical communication and it accelerates the transfer rate between the enzyme and the electrode. The atomic force microscopy assessment of the produced transducer has demonstrated that the nanostructured zirconia roughened the surface, therefore increasing the active surface area, and the electrochemical assessments (EIS and Chronoamperometry) of the produced electrodes have confirmed that by depositing the nanostructured zirconia thin films onto a conductive layer we are still able to maintain the electrochemical characteristics of the transducer and the detection of Thiocholine is possible. Also the compatibility of SCBD with planar fabrication techniques and additive manufacturing allows for the rapid and cheap fabrication of devices to be used in on-field portable detection systems.
