Scientific articles are written documents that present original research findings or reviews of existing studies. They are typically published in academic journals and are intended for researchers, scholars, and students. These articles follow a structured format, often including sections like abstract, introduction, methods, results, and discussion, which help readers understand the research process and outcomes. The primary purpose of scientific articles is to share knowledge and advance understanding in various fields, such as biology, chemistry, or physics. They undergo a peer-review process, where other experts evaluate the work for quality and validity before publication, ensuring that the information is reliable and credible.
