The purpose of this paper is to solve the issue of via filling and pattern plating simultaneously by concentration optimization of accelerator and leveler in the electroplating bath.

This paper designs a series of experiments to verify the performance of pattern plating with the via filling plating formula. Then the compositions of electroplating solution are optimized to achieve via filling and pattern plating simultaneously. Finally, the mechanism of co-plating for via and line is discussed in brief.

To achieve excellent performance for via filling and pattern plating simultaneously, proportion of additives are comprehensively considered in optimization of electroplating process. Effects of additives on the via filling and pattern plating should be taken into consideration, especially in achieving flat lines.

This paper discusses the different effects of accelerator and leveler on the via filling and the pattern plating, respectively. The process of co-plating for the via and the line is presented. The superfilling of via and the flat line are simultaneously obtained with the optimized via filling formula.

This study aimed to identify the characteristics of excellent peer reviewers by using Publons.com (an open and free online peer review website).

Reviewers of the clinical medicine field on Publons were selected as the sample (n = 1,864). A logistic regression model was employed to examine the data.

The results revealed that reviewers' verified reviews, verified editor records, and whether they were the Publons mentors had significant and positive associations with excellent peer reviewers, while their research performance (including the number of articles indexed by Web of Science (WOS), citations, H-index and high-cited researcher), genders, words per review, number of current/past editorial boards, whether they had experiences of post-publication review on Publons and whether they were Publons academy graduates had no significant associations with excellent peer reviewers.

This study could help journals find excellent peer reviewers from free and open online platforms.

Tantalum is a kind of metal material with moderate hardness, high ductility, small thermal expansion coefficient, excellent corrosion resistance and outstanding biocompatibility. The purpose of this study is that its tribological performance could be tested and analyzed so as to use it in different fields.

The friction resistance of a-Ta under dry friction conditions was tested at different roads. The relationships between load and friction coefficient, wear rate and two-dimensional shape of wear scars were studied.

The stable Ta₂O₅ film with lubrication effect was generated in the process of friction. And, the larger the test load, the more Ta₂O₅ would be generated.

This work lays a theoretical foundation for tantalum as an excellent wear-resistant material.
