Metal-organic framework (MOF) templated hierarchical Al-doped CoxP @ graphene composite: A promising solid-state asymmetric supercapacitor with PANI derived carbon nanorods
Get PDFThis register contains two pdf files, the main article and other of supplementary material.Metal phosphides are counted as smart electrodes for the supercapacitor field due to their fascinated capacity and conductive features. However, these materials are still suffering from lower conductivity, and significant changes in volume while cycling restricting their potential usage as cathode for such technology. In this study, a novel strategy was primarily established for building hierarchical Al-doped CoxP sheets on graphene as 2D on 2D nanoarchitecture with outstanding electrochemical properties. The hierarchical structure was formed through a cost-effective, and scalable hydrothermal method from a metal-organic framework followed by an efficient phosphorization step. Impressively, the graphene incorporation and Al doping besides morphology merit could largely improve the electrochemical properties of cobalt phosphide. Thus, the new material recorded an outstanding specific capacity as 312.3 mAh/g at an adjusted current density of 1 A/g which is relatively higher compared with the bare Al-CoxP with considerable capacitance retention of 87 % (at 40 A/g). Furthermore, the diffusion-controlled, and capacitive currents were differentiated using standard numerical packages in Python. Motivally, a solid-state asymmetric supercapacitor of Al-CoxP @ rGO//PCNRs was designed to give an ultrahigh energy density of 77.3 Wh/kg at a tuned power density of 1050.5 W/kg with remarkable cycling stability (90 % retention after 10,000 cycles).This research work is supported by the National Research Foundation of Korea (NRF) funded by the Ministry of Education (Grant Numbers: NRF-2019R1l1A3A010638331, NRF-2022R1I1A1A01069960) and NRF-2021R1I1A1A01059870), Hannam University research fund in 2024.

Impact of plasma polymerized Iodine-Doped thiophene films for enhanced sensing response towards industrial VOCs
Get PDFVolatile organic compounds (VOCs) are majorly used in the manufacturing industry and are hazardous to the sustainability of the environment. Polymeric sensors, rather than more traditional metal oxide sensors, are currently taking the lead attention in the greater part of VOC sensing investigations. In polymeric sensors, plasma polymerized thiophene (PPTh) films are being investigated because of their unique properties, wasteless fabrication, and feasibility for commercial mass manufacturing. In the present study, we fabricated PPTh films powered by a 13.6 MHz RF generator with a vacuum level of 10-3 Torr in a home-built plasma system. The gas sensor investigation of PPTh and iodine-doped PPTh samples with various VOCs, such as ethanol, methanol, acetone, benzene, toluene, and dichloromethane, was carried out systematically. The iodine-doped PPTh 10-20 films (48 hr) showed the highest sensitivity for ethanol (∼180) and methanol (∼120) as compared to PPTh for ethanol (∼110) at 1000 ppm gas concentration. A sensitivity degradation study over 60 days revealed the long-term stability of the films in the air. The polar hopping mechanism and decreased charge transport centers after reaction with the hydroxyl group are responsible for resulted sensitivity of iodine-doped PPTh films towards alcohols.This research is funded by the Rajiv Gandhi Science and Technology Commission, Mumbai, Maharashtra, India (File No: RGSTC/File2016/DPP-146/CR-36).

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
