You could try Google Scholar. I have access to paid science databases but don’t know of a specific science search engine.

See if you can access JStor from “home.” That is a good scholarly database in which you can do subject-specific searches.

My go to is Wolfram Alpha.

I like JSTOR and Academia.edu

I like the answers above. One more is Science Research. I haven’t used it but I got the link from a trusted source

Thank you all for responding. Hopefully these will prove helpful.

Which one of this is for free or all are paid?

@imrainmaker It looks like both JStor and Google Scholar are accessible mainly through libraries; although JStor has an individual paid subscription plan.

The Science Research site looks like it is free to individuals.

Science on StackExchange for Q&A.

Sci-Hub for journal articles.

@Espiritus_Corvus if you can join a library, often they have subscriptions to databases and therefore access to paid-for articles. The public library I worked in had the access only from within the physical building and the university library I work for now has a standalone PC for walk in access – read only so no copy and paste, download or print. Your library might offer an interlibrary loan service which might be cheaper than paying for the article online.

@Stinley The problem is that he’s asking for the Chinese guy.

Ok..Thanks @janbb for the info..))

Thank you, everybody. I’ll pass these along and hopefully, some of them are open to mainland Chinese.
