Examination of the thermal decomposition profiles of PMMA films by thermo-gravimetric analysis (TGA) established that increasing weight % of SMM results in both enhancement of the rate of decomposition initiated at “head-to-head” linkages along with suppression of the rate of decomposition initiated at vinylidene chain ends. In the case of PC films, the temperature at which the primary thermal decomposition occurs decreases with increasing weight % of SMM. The extent of these decomposition trends is correlated to the degree of SMM dispersal, as studied by transmission electron microscopy (TEM). Favourable interactions between the ligands coordinated to the SMMs and the polymer or solvent used in film preparation dictated the degree of SMM dispersal, with the ligand–polymer interactions being dominant on the nano-length scale (1–100 nm) and ligand–solvent interactions being dominant on the micro-length scale (>100 nm).Lucas P.

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
