Functional properties of innovative Nanosystems for Nanomedicine and Nanoelectronics (F3N)
No full textDuring the last five years, the interest of the international scientific community on innovative nanostructured materials increased exponentially. Only during 2012, more than 4400 papers having “nano” in the title have been published in international Journals (source ISI WEB of Science). In the frame of a previous cooperation, the Italian and Japanese teams involved in this project have been previously carried out a research activity with high level results (see the 5 significant papers published by the teams). On that basis the proposed F3N project will focus on the:
- synthesis and optimization at the nanoscale of functional nanosystems (e.g. SiC, Si, Ge, SiGe, ZnO nanowires-NWs) for nanomedicine
(cancer treatments and artificial retina) and bio-sensing applications as well as of SiC thin films for prosthetics
- defect evaluation and failure analysis of III-V- and Si-based optical and electronic devices
To optimize the NW properties, a methodological development of specific nanoscale characterization techniques will be carried out by complementing the know how and the advanced experimental set up of the Italian and Japanese teams
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
"Materials, devices and economics issues for tomorrow's photovoltaics" Symposium C of the European Materials Research Society - Strasbourg - Fall 2010 C
No full textPhotovoltaics (PV) is a source of electricity of very fast increasing investments and thanks to research it is strongly developing in view of energy saving. One of its main research goals is to increase the conversion efficiency and to reduce the manufacturing costs of solar modules and systems. In this respect the most ambitious target of the European Union (EU) Energy and Climate Package for 2020 is to increase by up to 20% the level of this renewable energy in the EU's overall final energy consumption. The PV industry has been growing at a steady annual rate of 25–30% over the past several years. This progress was driven chiefly, but not exclusively, by silicon-based solar cells, which now constitute nearly 90% of the global market, characterised by the use of very thin silicon wafers, advanced solar cell designs and processing, innovative module assembly.
At the same time, III–V, CIGS and CdTe solar cells are obtaining improved efficiency and raise a rapidly increasing interest by Industry. Additionally, the third-generation approaches to PV aim to achieve very high-efficiency devices for sunlight harvesting, but still use thin-film, second generation deposition methods in order to obtain technologies compatible with large-scale implementation of PVs by non-toxic and not limited in abundance materials.
In this frame major attention is paid to structural defects which result in deep-gap or tail states in thin films and are of great importance for the electronic quality of the PV materials. The influence of these states on structural properties of the films determines the performance of solar cells and investigation and understanding of such defects are still challenging.
This symposium will constitute an ideal forum for researchers of Academy and Industry to discuss state-of-the art results and promising developments in materials and devices for PV. It will be focused mainly, but not exclusively, to the following issues:
i) scientific aspects of the different approaches to PV for achieving high-efficiency low-cost materials/devices,
ii) the use of these materials/devices in the fields of energy saving, paying attention to the economic, environmental and political issues.
A mutual exchange of knowledge among scientists of Academy and Industry will be fruitful to approach the theoretical limiting efficiencies, in order to dramatically increase the performance of photovoltaic cells and greatly advance also the solar fuel producing technologies.
Hot topics to be covered by the symposium:
* novel materials for PV (III–V, CIGS and CdTe)
* 3rd generation PV
* thin film solar cells
* Si-based materials
* current issues in industry: advanced production processes
* political/economic issues
* defects engineering
* new developments for high PV efficienc
Variations on the Author
Full text link“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
Full text linkWe 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
Full text linkWe 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
