description: Traditional contact tracing tests the direct contacts of those who test positive. But, by the time an infected individual is tested, the infection starting from the person may have infected a chain of individuals. Hence, why should the testing stop at direct contacts, and not test secondary, tertiary contacts or even contacts further down? One deterrent in testing long chains of individuals right away may be that it substantially increases the testing load, or does it? We investigate the costs and benefits of such multi-hop contact tracing for different number of hops. Considering diverse contact networks, we show that the cost–benefit trade-off can be characterized in terms of a single measurable attribute, the initial epidemic growth rate. Once this growth rate crosses a threshold, multi-hop contact tracing substantially reduces the outbreak size compared with traditional tracing. Multi-hop even incurs a lower cost compared with the traditional tracing for a large range of values of the growth rate. The cost–benefit trade-offs can be classified into three phases depending on the value of the growth rate. The need for choosing a larger number of hops becomes greater as the growth rate increases or the environment becomes less conducive toward containing the disease.

description: We present calculations of frequency-dependent complex dielectric function of dense aluminum plasma by quantum molecular dynamics method for temperatures up to 20 kK. Analysis shows that the dependencies for real and imaginary parts can be interpolated by the Drude formula with two effective parameters: the mean charge of ions and the effective frequency of collisions. The rise of these parameters with temperature deviates from simple theoretical predictions.

description: Let $\mathfrak{L}$ be a Leibniz algebra, $E$ a vector space and $π: E \to \mathfrak{L}$ an epimorphism of vector spaces with $ \mathfrak{g} = {\rm Ker} (π)$. The global extension problem asks for the classification of all Leibniz algebra structures that can be defined on $E$ such that $π: E \to \mathfrak{L}$ is a morphism of Leibniz algebras: from a geometrical viewpoint this means to give the decomposition of the groupoid of all such structures in its connected components and to indicate a point in each component. All such Leibniz algebra structures on $E$ are classified by a global cohomological object ${\mathbb G} {\mathbb H} {\mathbb L}^{2} \, (\mathfrak{L}, \, \mathfrak{g})$ which is explicitly constructed. It is shown that ${\mathbb G} {\mathbb H} {\mathbb L}^{2} \, (\mathfrak{L}, \, \mathfrak{g})$ is the coproduct of all local cohomological objects $ {\mathbb H} {\mathbb L}^{2} \, \, (\mathfrak{L}, \, (\mathfrak{g}, [-,-]_{\mathfrak{g}}))$ that are classifying sets for all extensions of $\mathfrak{L}$ by all Leibniz algebra structures $(\mathfrak{g}, [-,-]_{\mathfrak{g}})$ on $\mathfrak{g}$. The second cohomology group ${\rm HL}^2 \, (\mathfrak{L}, \, \mathfrak{g})$ of Loday and Pirashvili appears as the most elementary piece among all components of ${\mathbb G} {\mathbb H} {\mathbb L}^{2} \, (\mathfrak{L}, \, \mathfrak{g})$. Several examples are worked out in details for co-flag Leibniz algebras over $\mathfrak{L}$, i.e. Leibniz algebras $\mathfrak{h}$ that have a finite chain of epimorphisms of Leibniz algebras $\mathfrak{L}_n : = \mathfrak{h} \stackrel{π_{n}}{\longrightarrow} \mathfrak{L}_{n-1} \, \cdots \, \mathfrak{L}_1 \stackrel{π_{1}} {\longrightarrow} \mathfrak{L}_{0} := \mathfrak{L}$ such that ${\rm dim} ({\rm Ker} (π_{i})) = 1$, for all $i = 1, \cdots, n$.

description: As the worldwide prevalence of hypertension continues to increase, the primary prevention of hypertension has become an important global public health initiative. Physical activity is commonly recommended as an important lifestyle modification that may aid in the prevention of hypertension. Recent epidemiologic evidence has demonstrated a consistent, temporal, and dose-dependent relationship between physical activity and the development of hypertension. Experimental evidence from interventional studies has further confirmed a relationship between physical activity and hypertension as the favorable effects of exercise on blood pressure reduction have been well characterized in recent years. Despite the available evidence strongly supporting a role for physical activity in the prevention of hypertension, many unanswered questions regarding the protective benefits of physical activity in high-risk individuals, the factors that may moderate the relationship between physical activity and hypertension, and the optimal prescription for hypertension prevention remain. We review the most recent evidence for the role of physical activity in the prevention of hypertension and discuss recent studies that have sought to address these unanswered questions.

description: Within a dynamical and statistical approach we study the main regularities in production of hypernuclei coming from projectile and target residues in relativistic ion collisions. We demonstrate that yields of hypernuclei increase considerably above the energy threshold for Lambda hyperons, and there is a saturation for yields of single hypernuclei with increasing the beam energy up to few TeV. Production of specific hypernuclei depend very much on the isotopic composition of the projectile, and this gives a chance to obtain exotic hypernuclei that may be difficult to reach in traditional hypernuclear experiments. Possibilities for the detection of such hypernuclei with planned and available relativistic ion facilities are discussed.

description: Over thirteen times more gamma-ray pulsars have now been studied with the Large Area Telescope on NASA's Fermi satellite than the ten seen with the Compton Gamma-Ray Observatory in the nineteen-nineties. The large sample is diverse, allowing better understanding both of the pulsars themselves and of their roles in various cosmic processes. Here we explore the prospects for even more gamma-ray pulsars as Fermi enters the 2nd half of its nominal ten-year mission. New pulsars will naturally tend to be fainter than the first ones discovered. Some of them will have unusual characteristics compared to the current population, which may help discriminate between models. We illustrate a vision of the future with a sample of six pulsars discovered after the 2nd Fermi Pulsar Catalog was written.

description: We report the detection of the Sunyaev-Zel'dovich (SZ) effect of galaxy cluster XLSSU J021744.1-034536, using 30 GHz CARMA data. This cluster was discovered via its extended X-ray emission in the XMM-Newton Large Scale Structure survey, the precursor to the XXL survey. It has a photometrically determined redshift $z=1.91^{+0.19}_{-0.21}$, making it among the most distant clusters known, and nominally the most distant for which the SZ effect has been measured. The spherically integrated Comptonization is $Y_{500}=(3.0\pm0.4)\times 10^{-12}$, a measurement which is relatively insensitive to assumptions regarding the size and redshift of the cluster, as well as the background cosmology. Using a variety of locally calibrated cluster scaling relations extrapolated to z~2, we estimate a mass $M_{500} \sim (1$-$2)\times 10^{14}M_{sun}$ from the X-ray flux and SZ signal. The measured properties of this cluster are in good agreement with the extrapolation of an X-ray luminosity-SZ effect scaling relation calibrated from clusters discovered by the South Pole Telescope at higher masses and lower redshifts. The full XXL-CARMA sample will provide a more complete, multi-wavelength census of distant clusters in order to robustly extend the calibration of cluster scaling relations to these high redshifts.

description: In this work, the method of two-particle azimuthal correlation functions is used to measure the correlations due to jets and elliptic flow in d+Au, Cu+Cu and Au+Au collisions at √sNN= 200GeV. The jet correlations measured in Cu+Cu and Au+Au collisions, are separated via a novel decomposition technique to obtain the jet associated particles per trigger hadron. These distributions show evidence for strong centrality dependent shape modifications for particles of intermediate transverse momentum produced in Cu+Cu and Au+Au collisions but not for d+Au . These new experimental results provide an important basis for further study of the transport properties of the high energy density matter produced in heavy ion collisions at RHIC.

description: These Sessional Clippings books cover the period 1891 to 1972, and include newspaper accounts written by various legislative reporters who covered debates occurring in the British Columbia Legislative Assembly. Transcripts of debates of the Legislative Assembly (Hansard) were not published in B.C. until 1970; hence these "Sessional Clipping Books" augment the "Journals", the record of daily proceedings of the Legislative Assembly. Selected clippings from various newspapers including the Vancouver Sun, the Vancouver Province, the Colonist, and the Times newspapers, relating to the newspaper reports concerning activities of the Legislature. The original sessional clippings books comprise 351 ledger size print volumes, held at the Legislative Library in Victoria BC. The print volumes were microfilmed onto 26 reels in 1977 under a Tri University Libraries (TRIUL) project by Precision Micrographic Services (Vancouver, B.C.), with the permission of the Legislative Library, Victoria, British Columbia. This digital collection was created by scanning the 26 microfilm reels.
title: An Assessment of Four Selected Communities Along the Appalachian Trail in Relation to Emile Benton Mackaye's Original Vision of Regional Planning
Creators: name: Schottanes, Jessica Ann
Publisher: name: University of Massachusetts Amherst
Year: 2021

description: Planner, conservationist, forester, and geographer Emile Benton MacKaye envisioned a revolutionary, extensive foot trail that would promote the interaction between communities throughout the United States' distinctive eastern region. His 1921 plan for the Appalachian Trail (A.T.) focused on balancing the basic requirements for life in and out of the urban context by developing an ‘indigenous’ environment and developmental mold (Bower 1962, 372). However, almost a century has passed, and MacKaye's approach to the planning process, organization, environmental development, and the rural economy remains hidden beneath the mountain forest canopy extending from Maine to Georgia.
Four of the forty-nine designated communities in the A.T. CommunityTM program today were analyzed to determine if and which aspects of Benton MacKaye's original vision of regional planning were achieved 100 years later. On-the-ground observations were collected through informal interactions with A.T. CommunityTM Supporters, unaffiliated businesses and organizations, and locals while traveling to each of the four A.T. regions, defined by the A.T. Conservancy (ATC). It was essential to understand if the designations transformed trailside neighborhoods into outdoor recreational and social hubs and shifted community perspectives toward the Trail and the ATC.
Although most people think of the A.T. purely in terms of the opportunities it provides for outdoor and wilderness experiences, it is also perceived as a critical focus for communities' economic growth and vitality. The research reveals that the program and its complimentary ‘Supporter’ system for local businesses are ineffective. The ATC branded these trail towns. Yet, no elements of MacKaye’s vision or community improvements have truly been recognized following A.T. CommunityTM designations within the last decade. Regardless of geographic, temporal, internal, and physical aspects, this outcome was consistent in all four case study communities (Monson-ME, Harpers Ferry-Bolivar-WV, Damascus-VA, and Hot Springs-NC).

On the distribution of orbits in affine varieties

description: Given an affine variety $X$, a morphism $ϕ:X\to X$, a point $α\in X$, and a Zariski closed subset $V$ of $X$, we show that the forward $ϕ$-orbit of $α$ meets $V$ in at most finitely many infinite arithmetic progressions, and the remaining points lie in a set of Banach density zero. This may be viewed as a weak asymptotic version of the Dynamical Mordell-Lang Conjecture for affine varieties. The results hold in arbitrary characteristic, and the proof uses methods of ergodic theory applied to compact Berkovich spaces.

The \textit{distance Ramsey number} $R_{\it D}(s,t,d) $ is the minimum number $n$ such that for any graph $ G $ on $ n $ vertices, either $G$ contains an induced $ s $-vertex subgraph isomorphic to a distance graph in $ \Real^d $ or $ \bar {G} $ contains an induced $ t $-vertex subgraph isomorphic to the distance graph in $ \Real^d $. We obtain the upper and lower bounds on $R_{\it D}(s,s,d),$ which are similar to the bounds for the classical Ramsey number $R(\lceil \frac{s}{[d/2]} \rceil, \lceil \frac{s}{[d/2]} \rceil)$.

description: This essay is itself a tentative opinion; invited as a comment and written in consequent haste, it cannot pretend to the grounding in research that underlie the essays Professors Anthony and McGarity have written. It does not attempt to say how to tell an interpretive rule from a legislative rule-rather, just to indicate that the stakes seem both higher than and different from those that the cases and Professor Anthony have generally discussed, and that a "binding in practical effect" approach will sweep with undesirable breadth. It will have succeeded if it promotes thought about the benefits of receiving advice, and the costs of inhibiting that by proceduralisms-thought that at the moment seems to me missing from the analysis. The courts seem to be seeing particular "trees," individuals who have complaints about the impact on them of advice they do not like. They seem not to be seeing the general advantages of receiving advice, the benefits of bureaucratic regularity, and the ways in which their approach may undercut both. Undoubtedly, it is desirable for agencies to engage in consultation as they develop important interpretations-advice repeatedly given, for example,, by the Administrative Conference of the United States-and indications are that this is often done. Consultation can be helpful to an agency that may wish its advice to be well informed, respected, and understood. But perhaps no Federal Register notice appears, or in some other ways a shortcut is taken past the usual regimes of section 553 or the tertium quid. Imposing the procedural requirement in the latter terms will have consequences beyond promoting good practice. Undoubtedly too, cases will remain in which courts will conclude that legislative rulemaking is required for work that an agency is trying to accomplish by publication rules. The Supreme Court's enigmatic decision in Morton v. Ruiz may be an example of a case in which the agency had not sufficiently employed legislative rulemaking to permit the use of publication rules; or it may reflect, more simply, a failure of adequate publication of what might have been a proper publication rule (a manual provision embodying the challenged interpretation). In my judgment, however, its most important thrust lies in its insistence that ad hoc decisionmaking by low-level bureaucrats must be avoided. The regrettable and perverse impact of strongly discouraging publication rulemaking would be sharply to diminish the effective resources available to control the exercise of low-level discretion.

description: This paper presents a study of the dependence of the simulated intensities of recombination lines from hydrogen and helium atoms on the number of $n\ell$-resolved principal quantum numbers included in the calculations. We simulate hydrogen and helium emitting astrophysical plasmas using the code Cloudy and show that, if not enough $n\ell$-resolved levels are included, recombination line intensities can be predicted with significant errors than can be more than 30\% for H~I IR lines and 10\% for He~I optical lines ($\sim$20\% for He~I IR recombination lines) at densities $\sim1\text{cm}^{-3}$, comparable to interstellar medium. This can have consequences in several spectroscopic studies where high accuracy is required, such as primordial helium abundance determination. Our results indicate that the minimum number of resolved levels included in the simulated hydrogen and helium ions of our spectral emission models should be adjusted to the specific lines to be predicted, as well as to the temperature and density conditions of the simulated plasma.

description: Compact, steady jets are observed in the near infrared and radio bands in the hard state of Galactic black hole transients as their luminosity decreases and the source moves towards a quiescent state. Recent radio observations indicate that the jets turn off completely in the soft state, therefore multiwavelength monitoring of black hole transients are essential to probe the formation of jets. In this work we conducted a systematic study of all black hole transients with near infrared and radio coverage during their outburst decays. We characterized the timescales of changes in X-ray spectral and temporal properties and also in near infrared and/or in radio emission. We confirmed that state transitions occur in black hole transients at a very similar fraction of their respective Eddington luminosities. We also found that the near infrared flux increase that could be due to the formation of a compact jet is delayed by a time period of days with respect to the formation of a corona. Finally, we found a threshold disk Eddington luminosity fraction for the compact jets to form. We explain these results with a model such that the increase in the near infrared flux corresponds to a transition from a patchy, small scale height corona along with an optically thin out flow to a large scale height corona that allows for collimation of a steady compact jet. We discuss the timescale of jet formation in terms of transport of magnetic fields from the outer parts of the disk, and also consider two alternative explanations for the multiwavelength emission: hot inner accretion flows and irradiation.

description: Assessing second language speaking has long been an important part of language testing in both large-scale assessment settings and in smaller scale classroom-based assessments. Accordingly, researchers in the second language (L2) assessment field have made efforts to establish a better understanding of the nature of speaking ability and its underlying competences. With speaking tests increasingly involving test takers’ performances on certain tasks, test takers are required to utilize their language knowledge by means of their strategic competence (i.e., skills necessary to put language knowledge into use), which has been considered an integral component of communicative language ability (e.g., Bachman & Palmer, 1996) and L2 speaking ability (e.g., Bygate, 1987; Fulcher, 2003). However, what strategic competence in speaking entails remains unclear, as its definition has varied greatly across different theoretical models and empirical studies. This paper provides a brief overview of the varying approaches to defining strategic competence, and reports on major empirical findings related to the conceptualization of this important facet of speaking ability, surveying the extensive literature in the broader fields of applied linguistics and L2 assessment in particular. The paper starts with (1) a review of the applied linguistics literature on the major influential approaches to understanding oral strategic competence, followed by (2) an in-depth review of how the L2 assessment literature has conceptualized strategic competence in relation to different theoretical models, and lastly, (3) a discussion of empirical studies examining strategic competence in the context of speaking test performance. The paper concludes with directions for future research.

description: Time-series classification is utilized in a variety of applications leading to the development of many data mining techniques for time-series analysis. Among the broad range of time-series classification algorithms, recent studies are considering the impact of deep learning methods on time-series classification tasks. The quantity of related publications requires a bibliometric study to explore most prominent keywords, countries, sources and research clusters. The paper conducts a bibliometric analysis on related publications in time-series classification, adopted from Scopus database between 2010 and 2019. Through keywords co-occurrence analysis, a visual network structure of top keywords in time-series classification research has been produced and deep learning has been introduced as the most common topic by additional inquiry of the bibliography. The paper continues by exploring the publication trends of recent deep learning approaches for time-series classification. The annual number of publications, the productive and collaborative countries, the growth rate of sources, the most occurred keywords and the research collaborations are revealed from the bibliometric analysis within the study period. The research field has been broken down into three main categories as different frameworks of deep neural networks, different applications in remote sensing and also in signal processing for time-series classification tasks. The qualitative analysis highlights the categories of top citation rate papers by describing them in details.

description: We analyzed X-Shooter/VLT spectra of 24 ClassIII sources from three nearby star-forming regions (sigmaOrionis, LupusIII, and TWHya). We determined the effective temperature, surface gravity, rotational velocity, and radial velocity by comparing the observed spectra with synthetic BT-Settl model spectra. We investigated in detail the emission lines emerging from the stellar chromospheres and combined these data with archival X-ray data to allow for a comparison between chromospheric and coronal emissions. Both X-ray and Halpha luminosity as measured in terms of the bolometric luminosity are independent of the effective temperature for early-M stars but decline toward the end of the spectral M sequence. For the saturated early-M stars the average emission level is almost one dex higher for X-rays than for Halpha: log(L_x/L_bol) = -2.85 +- 0.36 vs. log(L_Halpha/L_bol) = -3.72 +- 0.21. When all chromospheric emission lines (including the Balmer series up to H11, CaII HK, the CaII infrared triplet, and several HeI lines) are summed up the coronal flux still dominates that of the chromosphere, typically by a factor 2-5. Flux-flux relations between activity diagnostics that probe different atmospheric layers (from the lower chromosphere to the corona) separate our sample of active pre-main sequence stars from the bulk of field M dwarfs studied in the literature. Flux ratios between individual optical emission lines show a smooth dependence on the effective temperature. The Balmer decrements can roughly be reproduced by an NLTE radiative transfer model devised for another young star of similar age. Future, more complete chromospheric model grids can be tested against this data set.

title: UNDERSTANDING COMPLEX COACERVATION OF LOW CHARGE DENSITY COPOLYMERS AND LATEXES
Creators: name: Bryant, Nicholas

description: Many coatings only need to either be durable or fast drying, usually sacrificing long term stability in favor of quick setting, or vice versa. One coating type that cannot afford to sacrifice either performance feature is traffic paint. These paints are made up of a weak polycation, an anionic latex, and a volatile base which evaporates upon application. The high pH in the initial formulation deprotonates the polycation, rendering it charge neutral. However, upon evaporation, the resulting drop in pH allows for the electrostatic complexation between the polycation and the latex. The electrostatic interactions used in these formulations parallels that of complex coacervation, an associative liquid-liquid phase separation. In this thesis, we will take advantage of model coacervate systems to elucidate the design parameters necessary for the formulations to serve as paints.
We used a series of simplified systems, starting with a system consisting of a weakly cationic homopolymer and weakly anionic homopolymer before moving on to anionic copolymers with decreasing charge density, and ultimately an anionic latex. We investigated the effects of pH, charge stoichiometry, and salt concentration for each of these systems, using turbidimetry and optical microscopy as a means of measuring the extent of coacervation. We determined that, the removal of 99.9% of the charge on our polymers was necessary for coacervation to no longer occur. This can be achieved using either salt or pH, however, salt may be preferable, due to the inherent hazardous properties of highly acidic or basic solutions. Very excitingly, we were able to observe coacervation with latex particles. To our knowledge, there are no known observations of polymer-particle coacervation prior to this study.
These results suggest that the underlying physics and design principles associated with fast setting paints can be explored using complex coacervation, and that a much broader range of parameters can be used to control the setting of these materials, beyond just pH used in existing technology. Future efforts are still needed to better understand the effect that polymer chemistry has on the complexation of these materials, and how it also affects the mechanical and adhesive properties of coating produced by such formulations.

description: Diagnostic testing has long been valued by language testing researchers and practitioners for its ability to inform both teaching and learning. However, the number of well-developed diagnostic language tests is relatively low, most likely due to the difficulty in constructing a diagnostic test that incorporates a wide enough range of language skills. In recent years, the advancement of technologies has allowed for the development of several large-scale, computer-based diagnostic language tests, as well as more sophisticated measurement methods to conduct diagnosis. This article first provides the theoretical ground for how diagnosis has been conceptualized in language testing over the past 60 years. Then, several current approaches to operationalizing diagnosis in second and foreign language assessment, including both tests and methods, are reviewed. The article concludes with reflections on diagnostic testing in second and foreign language assessment at its current state, as well as recommendations for its future directions.

description: The Bayesian approach to inverse problems typically relies on posterior sampling approaches, such as Markov chain Monte Carlo, for which the generation of each sample requires one or more evaluations of the parameter-to-observable map or forward model. When these evaluations are computationally intensive, approximations of the forward model are essential to accelerating sample-based inference. Yet the construction of globally accurate approximations for nonlinear forward models can be computationally prohibitive and in fact unnecessary, as the posterior distribution typically concentrates on a small fraction of the support of the prior distribution. We present a new approach that uses stochastic optimization to construct polynomial approximations over a sequence of measures adaptively determined from the data, eventually concentrating on the posterior distribution. The approach yields substantial gains in efficiency and accuracy over prior-based surrogates, as demonstrated via application to inverse problems in partial differential equations.

title: Re-envisioning the American Dream
Creators: name: Tang, Elain

description: The United States of America is globally known as the land of opportunity, freedom, independence, equality, and above all, the American Dream. American writer and historian, James Truslow Adams, coined the phrase “American Dream” in his 1931 book The Epic of America. The American Dream is the belief that anyone, regardless of where they were born or what class they were born into, they can attain their own version of success in society through hard work, sacrifice, and taking risks. Post-World War II, the demand for home ownership rapidly increased. The development of Levittown provided single-family homes for white nuclear families, which was highly idealized by society and became a part of the American Dream.
Against this backdrop, this thesis project addresses the role of architecture in adapting existing communities to serve the more comprehensive view of today’s family structures. This development concept results in a supportive and flexible environment where families of all configurations and backgrounds are accepted. In doing so, its surrounding environment will be exposed to a multi-generational and multi-cultural community, resulting in a richer and more interactive environment. Numerous co-benefits emerge from this model, including flexibility within existing and new homes, a supportive community, and synergies between different family structures.

description: A surface modification of ultraflat gold nanotriangles (AuNTs) with different shaped nanoparticles is of special relevance for surface-enhanced Raman scattering (SERS) and the photo-catalytic activity of plasmonic substrates. Therefore, different approaches are used to verify the flat platelet morphology of the AuNTs by oriented overgrowth with metal nanoparticles. The most important part for the morphological transformation of the AuNTs is the coating layer, containing surfactants or polymers. By using well established AuNTs stabilized by a dioctyl sodium sulfosuccinate (AOT) bilayer, different strategies of surface modification with noble metal nanoparticles are possible. On the one hand undulated superstructures were synthesized by in situ growth of hemispherical gold nanoparticles in the polyethyleneimine (PEI)-coated AOT bilayer of the AuNTs. On the other hand spiked AuNTs were obtained by a direct reduction of Au³⁺ ions in the AOT double layer in presence of silver ions and ascorbic acid as reducing agent. Additionally, crumble topping of the smooth AuNTs can be realized after an exchange of the AOT bilayer by hyaluronic acid, followed by a silver-ion mediated reduction with ascorbic acid. Furthermore, a decoration with silver nanoparticles after coating the AOT bilayer with the cationic surfactant benzylhexadecyldimethylammonium chloride (BDAC) can be realized. In that case the ultraviolet (UV)-absorption of the undulated Au@Ag nanoplatelets can be tuned depending on the degree of decoration with silver nanoparticles. Comparing the Raman scattering data for the plasmon driven dimerization of 4-nitrothiophenol (4-NTP) to 4,4′-dimercaptoazobenzene (DMAB) one can conclude that the most important effect of surface modification with a 75 times higher enhancement factor in SERS experiments becomes available by decoration with gold spikes.

The Fabrication of Paper-based Multi-walled Carbon Nanotubes Electrode Sensors Using Inkjet Printer
Creators: name: Deeprasert, Saruta
Publisher: name: Lancaster University
Year: 2022

description: Paper-based electrode sensors are low-cost, biodegradable and easy to fabricate, and are usually developed for single-use detection, to avoid cleaning and cross-contamination. Nanomaterials have gained wide interest as key components for paper-based electrode sensors, as they can be easily deposited onto paper substrates. The aim of this research is to prepare a water-based multi-walled carbon nanotubes (MWCNTs) ink for paper-based electrode sensor fabrication using a home inkjet printer (Canon PIXMA TS205). Different MWCNTs ink formulations were studied to identify the most compatible inks for inkjet printing. Pristine multi-walled carbon nanotubes functionalised with a carboxylic acid group mixed with sodium dodecyl sulphate provided the optimum homogeneity with high electrical conductivity and compatibility with the inkjet printer. This formulation was used to fabricate the MWCNTs-based electrode sensor on Whatman filter paper. However, one of the major challenges with paper-based sensors is water absorption by the paper substrate, making it inappropriate for multiple uses. Three types of coating, perflourocyclobutane (PFC), acrylic acid (AA) and allylamine (AAm), were plasma polymerised onto the paper substrate to enhance the paper substrate stability and electrode sensor performance. The purpose of using PFC is to make the paper substrate surface hydrophobic, to prevent water absorption that may degrade the electrode sensor, while AA and AAm are plasma polymerised to induce hydrophilicity to the surface of PFC-coated filter paper for MWCNTs printing and electrode sensor fabrication. The success of the plasma polymerisation technique and improved performance of the sensor was confirmed using a range of analytical techniques. This PhD project foreshadows the future development of paper-based sensors with high durability and enhanced performance.
