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.

Researchers from Chinese Academy of Sciences Report Details of New Studies and Findings in the Area of Tribology (Synergistic Effect and Long-term Lubricating Mechanism of Ws2/oil Combinations Determined Via Oil Molecule Structures In Vacuum)

Article Description
WS 2 film with excellent lubricating property was combined with lubricating oils (PAO, PFPE and MACs) with different molecule structures to construct WS 2 /oil composite lubricating systems, respectively. The influences of the molecule structures and properties of oils on tribological properties of the systems were investigated systematically in vacuum. The result indicated that the WS 2 /PAO and WS 2 /MACs systems exhibited the obvious synergistic lubricating effect under relatively harsh testing condition, markedly prolonging the lubricating life and decreasing the wear rate. There is a new discovery that numerous ultrasmall WS 2 nanosheets were generated and uniformly adhered to friction contact area, further in-situ forming the tribolayer that significantly enhanced the lubricating life. The lubricating mechanism of the long lifetime for WS 2 /oil systems is finally revealed.
