Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
In this study, isotacitc polypropylene (iPP) samples were prepared by conventional injection molding (CIM) and sequential co-injection molding (SCIM), in which two kinds of polymer melt were injected into the mold cavity one after the other. The morphological structure of the samples was investigated by polarized light microscopy (PLM) and scanning electron microscopy (SEM). Results show that the structures of the samples prepared by CIM have a typical skin-core structure. This structure could be divided into three layers along the thickness direction of the samples: skin layer, transition region and core layer. However, the morphologies of the samples prepared by SCIM have a fascinating supermolecular structure that can not be roughly divided into three layers. A region of cylindritic structures, which is rare in CIM, is formed between the skin layer and the core layer of the second injected material. In particular, the cylindritic structures are more easily found when the melt temperature is relatively lower and the delay time is longer. The results were further interpreted based on the analysis and comparison of the thermo-mechanical history imposed on the melt during the CIM and SCIM processes. © 2013 Springer Science+Business Media Dordrecht.
