No full textAn EXAFS study on iron-cobalt-alumina nanocomposites prepared by the sol-gel method
No full textThe selectivity of the EXAFS (extended x-ray absorption fine structure) technique was used in order to gain insights on the structural evolution of the Fe and Co environment at different stages of the preparation of FeCo-Al 2O3 aerogels and xerogels. The gels, which were prepared using aluminium tri-sec-butoxide, iron nitrate and cobalt nitrates as precursors, were dried using different procedures in order to obtain xerogels and aerogels, respectively. After drying, the samples are treated either in air up to 900°C or in hydrogen up to 800°C

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
