This paper shows a nice review of Carbon-Based Nanofluids. There are some issues that need to address:

- 512 References! Fantastic!

The authors thank the respected reviewer for his kind words and for supporting us. Thank you very much.

What makes this review different from the others and from the most recent ones?

Thank you for your question. What makes this review different is that it guides the reader all the way from the carbon-based nanomaterials fabrication and all the way towards three major thermal applications in the industry and it provides the recent gap in the scientific knowledge, where the reader can tackle in his future research.

Section of drawbacks and future could be increased quality of the manuscript.

We thank the respected reviewer for his comment. We have taken this into consideration in our revised version. Kindly check Section 8.1 (Page 83 of 125) and Section 8.3 (Page 85 of 125) in our revised manuscript. Thank you very much.

Reviewer 3 Report

Heat transfer nanofluids is very interesting and challenging field. Authors try to give a comprehensive review about carbon based nanofluids and their advances towards heat transfer applications. The efforts are worthwhile.

The Authors

This manuscript is a resubmission of an earlier submission. The following is a list of the peer review reports and author responses from that submission.


Round 1

Reviewer 1 Report

  1. The reviewer thinks English is not the authors’ first language. The quality of the writing is needed to improve. The wrong structure, as well as punctuation in some sentences, prevents proper understanding.
  2. Please obtain permissions for figures’ reproduction.
  3. It will e more informative if a part of the paper covers the biofuels containing nanomaterials.
  4. Some references are older than 2015 and therefore, they are abolished. May the reviewer ask the authors to change these references to newer ones? Some suggested papers are as below: Heat transfer evaluation of a micro heat exchanger cooling with spherical carbon-acetone nanofluid. Effects on thermophysical properties of carbon based nanofluids: experimental data, modelling using regression, ANFIS and ANN.  Study of synthesis, stability and thermo-physical properties of graphene nanoplatelet/platinum hybrid nanofluid.  Investigation of heat transfer performance and friction factor of a counter-flow double-pipe heat exchanger using nitrogen-doped, graphene-based nanofluids.  A novel comprehensive experimental study concerned graphene oxide nanoparticles dispersed in water: Synthesise, characterisation, thermal conductivity measurement and present a new approach of RLSF neural network.
  5. When reviewing the references, a strong impression can be created that the manuscript should be submitted to another journal: To give journal readers a sense of continuity, the reviewer encourages the authors to identify Nanomaterials publications of similar research in your papers. Please, do a literature check of the papers published in recent years (2020 and even 2021) and relate the content of relevant papers to the results and findings presented in your publication. The authors can also reference articles in print using their DOI.
  6. Add some critical results to the introduction part.
  7. Refine the keywords.
  8. Carbon-based nanomaterials have a vast application in enhancing the quality of biofuels. To know more about the topic, you study 2020 & 2021 related papers like: Investigation on the effect of cottonseed oil blended with different percentages of octanol and suspended MWCNT nanoparticles on diesel engine characteristics. Effect of nano-graphene oxide and n-butanol fuel additives blended with diesel—Nigella sativa biodiesel fuel emulsion on diesel engine characteristics.
  9. The conclusion part should be summarized.
  10. Add a part to the article and talk about the environmental issues of carbon-based nanomaterials. You can see this paper for more information: Recent Advances in Using Nanofluids in Renewable Energy Systems and the Environmental Implications of their Uptake.
  11. Do you really think Fig.2 is necessary for the manuscript?

Therefore, we kindly ask the respected reviewer to allow us to maintain Fig. 2.

Thank you very much.

 

 

Reviewer 2 Report

This paper shows a good review of carbon-based nanofluids in heat transfer applications, there are some issues that need to address:

- Introduction is written simply, most recent research and innovation in nanofluids performances should be reviewed to show the gap of knowledge. Introduction should be extended with recently research papers.

- 499 References! Fantastic! Also, authors can cite the following work in the introduction which is closely related to their work and recently reported:

"Comprehensive study concerned graphene nano-sheets dispersed in ethylene glycol: Experimental study and theoretical prediction of thermal conductivity." Powder Technology 386 (2021): 51-59.

"A review on the control parameters of natural convection in different shaped cavities with and without nanofluid." Processes 8, no. 9 (2020): 1011.

what makes this review different from the others and from the most recent ones?

- section of drawbacks and future could be increased quality of the manuscript.

There are some grammatical errors, please carefully check the whole manuscript.

- The article size is very long; the additional description should be deleted and the additional tables should be merged.

Congratulations to the authors for their professional work. This article can be very useful for researchers and students.

We thank the respected reviewer for the suggestion. We do agree that the proposed two recent references would surely be an added value to our manuscript. As such, kindly note that we have included them in our revised version. Thank you very much.

Thank you for your question. What makes this review different is that it guides the reader all the way from the carbon-based nanomaterials fabrication and all the way towards three major thermal applications in the industry and it provides the recent gap in the scientific knowledge, where the reader can tackle in his future research.

Section of drawbacks and future could be increased quality of the manuscript.

We thank the respected reviewer for his suggestion. We have taken this into consideration, but in an indirect way within our revised manuscript. Kindly note that we have included a stand-alone section, Section 7 (Environmental Consideration and Potential Health Issues), which is usually seen included as part of the drawbacks and future section, but we wanted it to be a stand-alone section for better deliverability purposes. Thank you very much

There are some grammatical errors, please carefully check the whole manuscript.

We apologise for any inconveniences. We have revised the English language of the whole manuscripts in its revised version. Thank you very much.

The article size is very long; the additional description should be deleted and the additional tables should be merged.

We thank the respected reviewer for his suggestion. The journal has not limit on the number of pages or the materials content. We also would like to be comprehensive about our literature survey. Therefore, we have found that adopting the detailed and informative form of a review article is very favourable by many readers in the field (based on the number of downloads and citations), and thus we tried to write our review article in a similar way to those published by elite scientific publishers. We kindly ask the respected reviewer to allow us to maintain the size of the manuscript. We do apologize for any inconveniences. Thank you very much for your highly respected suggestion.

Congratulations to the authors for their professional work. This article can be very useful for researchers and students.

The authors would like to thank the respected reviewer very much for his time and for his encouragements.
