Metric Options: Counts1 Year3 YearSelecting 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
Layered structures of cubic yttria-stabilized zirconia (YSZ) sandwiched between two layers of platinum/YSZ composites with the platinum concentration varying between 20 and 55 vol % were prepared. Large double-layer capacitances were obtained due to the presence of large three-dimensional electrode surface areas in the composite layers. The layers were subjected to image analysis obtained from scanning electron microscopy micrographs. The specific surface area of the platinum particles decreased from ∼ 17 × 10 to ∼ 13.5 × 10 cm/cm with increasing Pt concentration. Image analyses obtained with an in-lens detector revealed that the effective surface area of the Pt particles that were part of a conducting percolative network increased with Pt concentration to ca. 11 × 10 cm/cm at a Pt metal volume fraction of 0.50. Impedance spectroscopy measurements performed at 550°C demonstrated that the capacitance increased with increasing Pt concentration in the composite layer and optimal values as high as 4.3 ± 1.3 kF/m at 50 vol % Pt were recorded. The specific electrode surface area calculated from this data was in good agreement with the data obtained from image analysis. © 2001 American Institute of Physics.
