Are scientific writing sources a breach of policy?

[Themoose]

Hello, I have a website related to engineering. I research numerous English sources on a topic and write articles by translating them entirely myself and adding my own insights. I do not use any translation tools like Google Translate, the translations are my own. The website includes pages such as About Us, Privacy Policy, and Contact (with address, map, email, and contact form). I initially thought of having multiple authors for the site, but currently, I am the sole author. Given the engineering focus and the need for reliable content in this field, under each article, there is an option to add the author's name, bio, photo, and mandatory links to LinkedIn and other social media accounts for credibility. Additionally, in every article I write, I share the sources I have used for reference and further reading using the nofollow tag and mentioning the time when the source was used to ensure credibility and respect for the effort. Am I violating any policies with the content I write? What else should I add or remove? Are the sources causing Google to perceive my content as duplicate? Do I need to remove the sources to comply with Google's terms? When designing the website, I reviewed various popular sites that publish content on different topics but parallel to my system's purpose (such as Scienceteller, EvolutionTree, Physicist, etc.) that also share article sources, but they have been approved for AdSense. I am a bit confused and would appreciate your feedback. Wishing you productive work ahead.
