Special Issue Information
Dear Colleagues,
Inspired by the lotus leaf, highly-water-repellent superhydrophobic surfaces (SHSs) are garnering growing interest due to their wide engineering and biomedical applications, such as drag reduction, heat and mass transfer enhancement, anti-corrosion, anti-icing and anti-fouling activities. Among these applications, maintaining a stable layer of gas within the surface texture of the SHS is crucial. The gas layer not only reduces the contact area between the liquid and solid, but also enables the liquid to slip along the surface. Without the trapped gas, the SHS becomes a regular rough surface and loses most of its functions. However, the stability of gas on SHSs is affected by many factors, including pressure, gas diffusion and turbulent flows, limiting the broad application of SHSs. Understanding and enhancing the stability of SHSs is currently an urgent task for the scientific community. This Special Issue aims to collect contributions on three topics: (i) experimental and numerical studies that seek to fundamentally understand interactions between SHSs and surrounding environments; (ii) innovative solutions that enhance the stability and longevity of SHSs; and (iii) novel applications of SHSs such as reducing drag in high-Reynolds-number turbulent flows.

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. Biomimetics 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 2200 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.
