It is a way to express the author's gratitude and praise to the people, institutions, tutors, colleagues, family members and so on who helped and supported in the research process. The thank-you part is an expression of gratitude to these people, which can be a short paragraph or an independent chapter.
Usually, the content of thanks should include the following aspects:
Mentor and guidance: Thank your mentor for your guidance, advice and support in your research work.
Collaborators and colleagues: thank and praise colleagues, research team members or collaborators who have cooperated with you and provided help and advice.
Laboratories and institutions: thank the institutions, departments or research units that provide laboratory facilities, technical support, research funds or other resources.
Experts and scholars: Thank you for your valuable opinions, comments and discussions from experts, scholars or researchers in other fields.
Family and friends: Thank your family and friends for their understanding, support and encouragement of your research.
When writing thanks, express sincere thanks and express them in concise and clear language. Don't be too verbose, but be sure to cover all the people and institutions that should be thanked.
Finally, it should be noted that each academic institution and journal may have different paper formats and structures, so when writing the thank-you part of the paper, it is best to refer to the guidelines or requirements of academic institutions or journals to ensure that they meet their prescribed formats and requirements.
