Special Issue Information

Dear Colleagues,

The journals “Materials”, “Coatings”, and “Inorganics” invite submissions of original research articles for a joint Special Issue on "Thermoelectric Materials for Sustainable Applications". With the increasing demand for clean energy sources and the need for the more efficient use of energy, thermoelectric materials have gained significant attention as a promising technology to convert waste heat into useful electricity. This Special Issue aims to collate the latest research findings in the field of thermoelectric materials, with a focus on their sustainable applications.

We particularly encourage contributions from colleagues who will attend the symposium B1 "Thermoelectric Materials for Sustainable Applications" IUMRS-ICA/MRM conference (Kyoto, December 11th–16th, 2023).

Topics of interest include, but are not limited to:

the synthesis and characterization of new thermoelectric materials; the modelling and simulation of thermoelectric materials; the development of advanced thermoelectric devices; the integration of thermoelectric materials in energy systems;  the recycling and sustainable production of thermoelectric materials;  the life cycle analysis of thermoelectric materials and systems; and the economic and environmental assessment of thermoelectric systems.

We welcome both theoretical and experimental studies, as well as review articles, that provide comprehensive and up-to-date overviews of specific topics within the scope of the Special Issue.

All submissions must be original research articles that have not been previously published or are not under consideration for publication elsewhere. All papers will be peer-reviewed by independent experts in the field. The three journals adhere to high standards of scientific quality and ethical standards in publishing. For information on submission guidelines and formatting requirements, please visit the journals’ websites.

Please contact us if you have any questions on the submission process.

We look forward to receiving your submissions!

You may choose our Joint Special Issue in Materials and Joint Special Issue in Inorganics.

Sincerely,

Prof. Dr. Paolo Mele
Dr. Giovanna Latronico

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Coatings is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Single-walled carbon nanotubes (SWCNTs) offer promise as materials for thermoelectric generators (TEGs) due to their flexibility, durability, and non-toxic nature. However, a key barrier to their application lies in their high thermal conductivity, which hampers the generation of temperature differences in TEGs. To address this challenge, we explored a method of enhancing the heat dissipation of SWCNT-based TEGs by coating SWCNT layers onto polymer mesh sheets. During TEG fabrication, achieving stable n-type SWCNT/mesh sheets proved considerably more challenging than their p-type counterparts. This difficulty stemmed from the inferior dispersibility of the n-type SWCNT ink compared to the p-type SWCNT ink. To produce n-type SWCNT/mesh sheets, we initially prepared p-type SWCNT/mesh sheets using p-type SWCNT ink, subsequently doping them with a cationic surfactant solution to induce n-type characteristics. To stabilize the n-type thermoelectric properties in SWCNT/mesh sheets, we applied a fluoropolymer coating to the SWCNT surfaces, mitigating the adsorption of oxygen molecules. This approach yielded n-type SWCNT/mesh sheets capable of long-term maintenance. Furthermore, flexible TEGs fabricated using both p- and n-type SWCNT/mesh sheets demonstrated an output voltage of 15 mV, which can operate IoT sensors using the latest booster circuits, and a maximum power of 100 nW at a temperature difference of 71 K.
