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
This paper describes series of four-ball tribological and atomic force squeezing test results obtained under different contact pressures and sliding speeds (or squeezing speeds) and performed with poly-alpha-olefin suspended 0.5% weight percentage of different types of carboxylic acids. Results indicated that under a confined zone (contact pressures varied from 2.4~3.9 GPa), there is a critical turning speed at which the friction performances of carboxylic acid change dramatically. When the sliding speed exceeds the critical turning speed, carboxylic acid molecules or their incomplete decomposition products would adsorb, deposit, and spread in the friction surface, thus form an island–like aggregate tribofilm with an approximately thickness of 150 nm achieving a super–low wear.
