Do adsorbent screening metrics predict process performance? A process optimisation based study for post-combustion capture of CO2
No full textRecent interest in carbon dioxide capture has led to development of hundreds of adsorbents. The selection of the adsorbents and analyzing their performance for a given process is a challenging task. Usually, the expected performances of these adsorbents are evaluated by inspecting the isotherms and using simple adsorbent screening metrics (selectivities, working capacities, figures of merit, etc.). In this work, a process-optimization based approach to screen adsorbents for post-combustion CO2 capture for vacuum swing adsorption (VSA) is presented. Four different adsorbents (Mg-MOF-74, UTSA-16, Zeolite 13X and activated carbon) were chosen as test materials and were subjected to process-optimization studies on a 4-step PSA cycle with light product pressurization (LPP). Two kinds of process optimization studies were performed. The first to maximize purity and recovery and the second to minimize energy consumption and maximize productivity subject to purity/recovery constraints. This study highlights that most commonly used adsorbent metrics do not necessarily rank the performance of the materials at a process scale. It is also shown that the process performance was more sensitive to the affinity of N2 than that of CO2.Fil: Rajagopalan, Ashwin Kumar. University of Alberta; CanadáFil: Avila, Adolfo María.

Asymptotically nonliner oscillatory shear: theory, modeling, measurements and applications of nonlinear elasticity to stimuli-responsive composites
Get PDFViscoelastic materials, such as crosslinked networks of synthetic and biological polymers, exhibit a nonlinear rheological response to mechanical deformation. Oscillatory shear is a popular deformation protocol for viscoelastic characterization, both linear and nonlinear, the latter referred to as large amplitude oscillatory shear (LAOS). However, the accompanying nonlinear material response in LAOS is challenging to interpret and requires non-trivial material descriptions. The goal of this thesis is to provide a new paradigm of nonlinear rheological characterization using oscillatory shear deformation as well as to demonstrate applications of nonlinear viscoelastic materials, involving stimuli responsive polymer-colloid composites.
A nonlinear viscoelastic response in LAOS is high dimensional, covering the entire range of the 2D Pipkin space of deformation amplitude and frequency. A low-dimensional language and framework is introduced for viscoelastic characterization using asymptotic material functions in oscillatory shear, referred to as medium amplitude oscillatory shear (MAOS). These material functions, four in number, emerge from an asymptotic expansion in deformation amplitude and depend only on the oscillatory frequency. They carry physically meaningful inter- and intra-cycle information, for example, softening/stiffening and thickening/thinning of the stress response. For the first time, experimental measurements are shown for all four asymptotic nonlinearities.
Parallel disk measurements in the MAOS regime require a correction for the apparent stress response. In this regime, the derivatives appearing in the general stress correction are constant over the range of interest, and this allows exact single-point corrections for all four asymptotic nonlinearities. Experimental measurements are presented for the asymptotically-nonlinear signals on an entangled polymer melt, using both parallel disk and cone fixtures. The corrected (amplified) parallel disk signals match the measurements with the cone.
Using a fourth order fluid expansion, universal frequency scaling and interrelations are derived for asymptotic nonlinearities in the terminal regime, defined by the limit of De<<1. Experimental measurements, consistent with such predictions, are presented for an entangled polymer melt in the terminal regime. Beyond the terminal regime, at higher frequencies, signs and magnitudes cannot be universally predicted, leaving these as free parameters that depend on the specifics of the material microstructure or constitutive model.
A library of expectations of signatures (or fingerprints) is developed for all four asymptotically-nonlinear material functions for seven nonlinear constitutive models. The fingerprints are different in magnitude, frequency-scaling, curve shapes and sign changes, and distinguish the models. They obey the terminal regime inter-relations and frequency scaling, and are driven by strain-rates at small De and strains at large De. Some constitutive models exhibit multiple sign changes at intermediate De and there may be no universal behavior of asymptotically-nonlinear fingerprints in this regime. Therefore, frequency-dependent signatures can be material-specific.
Frequency-dependent asymptotically-nonlinear fingerprints are presented for a strain stiffening transiently-crosslinked polymeric hydrogel of aqueous polyvinyl alcohol (PVA) cross-linked by sodium tetraborate (borax). A transient network model with strain-stiffening elements is developed, and this predicts the asymptotically-nonlinear signatures of the PVA-Borax system that no other model predicts. The quantitative agreement provides fit parameters that are related to molecular features and network architecture. In conclusion, asymptotically-nonlinear descriptions enable structure-rheology insight, constitutive model development, and model selection for soft materials.
As examples of nonlinear viscoelastic materials, polymer/colloid composites are developed with field responsive nonlinear elastic mechanical properties. A large mesh semi-flexible network of bovine fibrin is nonlinear elastic and stiffening, and serves as the scaffold. Methods are described to fabricate fibrin-colloid composites that preserve network integrity and nonlinear stiffening properties. The strain-stiffening fibrin network is combined with stimuli-responsive colloids that respond to temperature and magnetic field, resulting in field-controllable elastic stiffening of the network.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2018-08-01The student, Narayanan Ashwin Kumar Bharadwaj, accepted the attached license on 2016-06-15 at 11:57.The student, Narayanan Ashwin Kumar Bharadwaj, submitted this Dissertation for approval on 2016-06-15 at 12:05.This Dissertation was approved for publication on 2016-06-16 at 16:33.DSpace SAF Submission Ingestion Package generated from Vireo submission #9669 on 2016-11-10 at 12:24:30Made available in DSpace on 2016-11-10T18:39:08Z (GMT).

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
