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
Two different types of inorganic silica fillers, nano-silica powder (NSP) and colloidal silica sol (CSS) were added into isotactic polypropylene (iPP) with low silica content (0.2 wt%) and the influence of the two silica fillers on the crystallization behavior and mechanical properties of iPP were investigated. Differential scanning calorimeter (DSC) results showed that the crystallization temperature of iPP with CSS and NSP were increased by 4.1 ˚C, and 2.4 ˚C, respectively. The tensile strength, flexural strength, and izod impact strength of iPP/CSS (33.75 MPa, 33.04 MPa, and 4.80 kJ/m)were higher than that of iPP/NSP (32.09 MPa, 32.27 MPa, and 4.25 kJ/m). In addition, the haze value of iPP/ CSS was decreased from 37.6 % to 27.6 %, which was 4.7 % lower than that of iPP/NSP (32.3 %). The better performance of CSS as ascribed to its better dispersion ability in iPP matrix than NSP, and it was verified by scanning electron micrograph (SEM) and transmission electron microscope (TEM). Overall, these results indicated that inorganic silica sols had a potential application in the nanoparticle-reinforced composites field.
