The English editor (scientific editor) not only polished the English of our manuscript, including grammar, punctuation, and overall readability, but also significantly contributed to the academic expression by providing constructive feedback on the paper's framework, constituent elements, results, and conclusions. This included appropriately compressing lengthy or repetitive sections, suggesting structural modifications, identifying ambiguous passages, rewriting academic descriptions, questioning certain statements in the paper, and offering constructive academic suggestions. All of these insights and assistance have been very inspiring and helpful for us as authors. Thank you very much to the editor.

The article was polished only once and accepted to publish. LetPub is very professional and the language polish is excellent! Thank you very much!

I am very grateful to LetPub for its editing of papers, professional language modification and timely feedback of papers. I look forward to cooperating with LetPub again in the future.

The editor made grammatical changes to the article: such as the correct use of "a" and "the". In addition, the editor also modified the expression. After revision, the article is smooth and easy to understand.

This is the second time I've polished my paper, and I have been recommending my classmates in the laboratory to edit their papers with LetPub. The effect of the revision is quite good, and the revision is very comprehensive and careful. After submission, the reviewer did not raise any questions about the language of the paper. LetPub's account manager is also very enthusiastic and responsible. They patiently communicate, and answer any questions, provide good service, and even send emails during the holidays.

LetPub is quick, the customer service is good, and the quality of the polished articles is great. The article was successfully accepted by the editorial department!

Thank you for a great cover design! From the initial evaluation to finalizing the design, the LetPub team worked very professionally. The entire cover art production process was pleasant and efficient, and the cover illustration was successfully selected by Nano Letters. Overall I'm very satisfied with their work. My client manager Viola has provided excellent service. She always communicated and replied to me promptly. Thanks again!

As a whole, LetPub is highly professional in language editing, and the service is also very considerate. Thank you LetPub for its timely and effective help on the long road of my paper publication!
