Proton Conductivity Studies of Zirconium Silicate/Ionic Liquids Membranes for PEM Fuel Cells Applications
No full textA Master of Science thesis in Chemical Engineering by Rana Muhammad Nauman Javed entitled, “Proton Conductivity Studies of Zirconium Silicate/Ionic Liquids Membranes for PEM Fuel Cells Applications”, submitted in December 2020. Thesis advisor is Dr. Amani Al-Othman and thesis co-advisor is Dr. Paul Nancarrow. Soft copy is available (Thesis, Completion Certificate, Approval Signatures, and AUS Archives Consent Form).This work reports the synthesis of a novel, high-temperature composite membrane for proton exchange membrane (PEM) fuel cells. High-temperature operation (> 100oC) is preferred in PEM fuel cells as it results in better water management and an enhancement to the overall kinetics of fuel cells’ electrodes. The current state of the art Nafion membrane is not suitable for high-temperature operation as their proton conductivities decline drastically. Hence, a novel Nafion-free membrane, based on zirconium silicates (ZrSi) and ionic liquids (ILs) is described in this thesis. Proton-conducting ZrSi/IL composite membranes were synthesized via precipitation of ZrSi/IL within the pores of polytetrafluoroethylene (PTFE) at room temperature. Seven different ILs were investigated to produce ZrSi/IL modified materials with ILs content ranging from 0.56% to 32% by mass. Significant enhancements in proton conductivities were observed upon the addition of the IL to ZrSi. Electrochemical impedance spectroscopy measurements showed proton conductivity values in the range of 0.1-0.2 S/cm, exceeding that of the Nafion membrane. The modified ZrSi/IL samples were further investigated by thermogravimetric analysis (TGA), scanning electron microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), X-ray diffraction (XRD), and energy-dispersive X-ray spectroscopy (EDX). TGA analysis of the modified ZrSi/IL materials demonstrated an approximately 20% weight loss at around 500°C . Water uptake analysis indicated that the new composite membrane could hold more than 50% by weight of water. SEM analysis showed the changes in particles' morphology of the modified ZrSi/IL. The interactions of ILs with ZrSi were studied using FTIR & XRD. Changes in the ZrSi/IL crystalline structures in comparison with pure ZrSi were observed. The samples processed at a high-temperature (200°C ) and exhibited a high proton conductivity in the order of 0.001 S/cm. Thus, the ZrSi/IL membranes reported in this work are very promising as proton conductors for high-temperature fuel cell applications.College of EngineeringDepartment of Chemical EngineeringMaster of Science in Chemical Engineering (MSChE
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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

BACKGROUND: ADP P2Y12 inhibitors are routinely administered after percutaneous coronary intervention (PCI) to prevent stent thrombosis. The newer P2Y12 inhibitors, prasugrel and ticagrelor, reduced the incidence of major adverse cardiac events (MACE) compared with clopidogrel in clinical trials of acute coronary syndrome (ACS) patients, but have received limited study in routine clinical practice.
OBJECTIVE: To compare the outcomes of prasugrel and ticagrelor with clopidogrel in real world ACS patients undergoing PCI.
METHODS: The medical records of all patients who underwent PCI at our institution between January 2011 and November 2013 were reviewed. The 12- month incidence of MACE (death, myocardial infarction, and repeat coronary revascularization) and bleeding was compared between patients who received a novel P2Y12 inhibitor (prasugrel or ticagrelor) and a random sample of those who received clopidogrel.
RESULTS : Two hundred and one patients who underwent PCI for ACS were included: 80 received either prasugrel or ticagrelor and 121 received clopidogrel. Mean age was 63.7 ± 9.3 years and 99% of the patients were men. The two study groups had similar baseline characteristics. The 12-month incidence of MACE in the novel P2Y12 inhibitor subgroup was 23% versus 33% in the clopidogrel subgroup (p = 0.25). Patients receiving prasugrel or ticagrelor had lower incidence of all cause (p < 0.01) and cardiac (p = 0.05) death, and similar incidence of bleeding.
CONCLUSION: In a non-selected ACS population use of a novel P2Y12 inhibitor was associated with lower incidence of death and similar incidence of bleeding as compared with clopidogrel.Southwestern Medical Foundatio
Variations on the Author
No full text“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
No full textWe 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
No full textWe 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
