Special Issue Information
Dear Colleagues,
High gravity refers to the force exerted on material in an environment, which has much larger acceleration than the Earth’s gravitational acceleration (9.8 m/s2). On Earth, a high gravity environment is usually achieved by the centrifugal force generated by rotation. High gravity devices mainly include the rotating packed bed, rotating disk, rotating baffled bed, and so on.
Under the high gravity environment created by high gravity devices, liquid is sheared into micron to nanoscale liquid droplets, film, or ligaments. In addition, fluids are highly turbulent, and the interface between them is updated rapidly. All these lead to a great enhancement of micromixing and mass transfer with 1–3 orders of magnitude higher than that in conventional devices, increasing the macroscopic reaction rate. Consequently, the production efficiency per unit equipment volume can be greatly improved to decrease the volume of a device. Therefore, high gravity technology is considered a breakthrough technology to strengthen the transfer and heterogeneous reaction process, and high gravity devices are known as “transistors of chemical industry”.
At present, high gravity technology has been successfully applied to gas absorption, dust removal, water deoxidation, wastewater treatment, biological fermentation, nanomaterial preparation, desulfurization alkali regeneration, devolatilization, catalyst synthesis, organic synthesis, distillation, electrochemical reaction, polymerization, etc., exhibiting remarkable strengthening effects. High gravity technology has drawn more and more attention, and its application field has been gradually expanded.

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. Applied Sciences 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 2400 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.
