Special Issue Information
Dear Colleagues,
Supercritical fluid (SCF)-based techniques are attracting growing interest as a green alternative to traditional processes, thanks to the properties of SCFs, such as liquid-like densities and gas-like transport properties that can be tuned to varying process operative conditions (i.e., pressure and temperature). In particular, carbon dioxide (CO2) is the most frequently used supercritical fluid due to its mild critical temperature (31.1 °C), low critical pressure (73.8 bar), and inertness. Depending on the role played by supercritical CO2, different processes have been successfully used for the production of polymeric aerogels and membranes, to coprecipitate drugs with biopolymers, and to produce micro- and nanoparticles.
The aim of this Special Issue is to present research and review papers on different supercritical CO2 applications in the pharmaceutical, biomedical, food, and energy fields. Contributions dealing with the supercritical processing of polymers and the attainment of polymer/nanoparticles or polymer/drug composites in the form of aerogels, foams, and membranes, or polymeric micro- and nanoparticles are welcome.
Dr. Lucia Baldino

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. 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.

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.
