Advances in Preparation and Characterization of Nanocrystalline Diamonds and Their Applications

Dear Colleagues,

Diamond is an allotrope of carbon and has attracted much researcher attention due to its physical and chemical properties. Nanocrystalline diamond is a type of carbon material, typically formed via the chemical vapor deposition (CVD) method, which displays outstanding properties, such as low self-friction coefficient, high wear and corrosion resistance, super hardness, bio-tolerance, and high thermal conductivity. Therefore, nanocrystalline diamond has great potential applications in cutting tools, mechanical seals, biomaterials, sensors, and thermal spread substrates.

Recent evidence has indicated that the properties of nanocrystalline diamond are related to its grain size. Hence, it is important to develop new preparation approaches to obtain diamond products with about 5 nm or lower grain size. This finding introduces a significant challenge for researchers to develop new machining and characterization methods.

In this Special Issue, recent advances in nanocrystalline diamonds, including bulk material or thin film preparation, machining, characterization, and applications, will be highlighted and discussed.

It is my pleasure to invite you to submit your research to this Special Issue. Full papers, communications, and reviews are all welcome.

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 250 words) can be sent to the Editorial Office for assessment.

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. Materials is an international peer-reviewed open access semimonthly 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.
