Natural chemistry, etc. , the level is lower and the positioning is higher. It is still difficult to publish landmark papers in the corresponding disciplines, with 200 or 300 papers published a year. To some extent, it can be considered that there is no obvious difference between the quality of natural science sub-journals and NS, and the difference may be that the articles on NS have more general interest.

As for nature communications, nature locates it between pnas and nature, and publishes some important achievements online. There are no paper publications, and they are basically open source. On the one hand, it is also the trend of open source of periodicals, and now the number of articles published in a year has reached about 5000.

As for SR, I don't need to say more. I can understand the quality of the article by myself. It is a low-grade periodical under the nature collective. The whole ngp is like a mobile phone, with high-end, mid-range and low-end periodicals. In fact, it is to cover more and make more money. We can get traffic through brand journals, and then get funds through the following journals (NC/SR), which is euphemistically called open source. Well, you have a lot of internet thinking. Of course, the quality of NC articles is still excellent, although it is criticized as too expensive!
