Special Issue Information

Dear Colleagues,

The main purpose of this Special Issue is to collect top theoretical and experimental works on nanobubbles and provide a collection of the newest research achievements in this important field. It is widely known that the most common definition for nanobubbles (NBs) is that they are nanoscopic gaseous cavities with a diameter of less than 1 μm. Nanobubbles (NBs) is a generic term to describe two distinguished cases of bubbles in a liquid—surface and bulk bubbles being in the nanoscale size. Surface nanobubbles (SNBs) refer to a pocket-like space filled with gas with a height no less than 10 nm and the area that it occupies ranging from 7850 to 78,500 nm2. In the case of bubbles with a size less than 1 μm suspended in a liquid, the term bulk nanobubble (BNBs) is used instead. The nanoscale dimension and composition challenge the development of new imaging, tracing, and analytical techniques operating in situ with high spatial and time resolutions. Additionally, today, there are numerous applications in various commercial fields employing heterogeneous catalysis, electrochemistry, photochemistry, coating processes, lake management, wastewater treatment, cleaning, immersion lithography, general separation processes, as well as biomedicine and drug delivery, steadily attracting increasing interdisciplinary attention. This Special Issue on “Nanobubbles” seeks high-quality works and topics focusing on (but not limited to) the latest approaches to nanobubbles. All researchers working in the field of nanobubbles are cordially invited to contribute original papers (research or review articles, etc.) to this Special Issue of Nanomaterials, which covers areas outlined in the scope as:

  • Nanobubbles in medical, biological, and environmental sciences;
  • Detection, imaging, manipulation, and tracking methods;
  • Physicochemical and -mechanical properties of nanobubbles;
  • Nanobubble formation, stability, composition, interactions;
  • Nanobubbles on immersed solid surfaces (surface nanobubbles) and in the bulk of liquid;
  • Solitary nanobubbles, nanobubble assemblies;
  • Any relevant topic to nanobubbles.

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. Nanomaterials 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.

Nanobubbles are classified into surface and bulk. The main difference between them is that the former is immobile, whereas the latter is mobile. The existence of sNBs has already been proven by atomic force microscopy, but the existence of bNBs is still open to discussion; there are strong indications, however, of its existence. The longevity of NBs is a long-standing problem. Theories as to the stability of sNBs reside on their immobile nature, whereas for bNBs, the landscape is not clear at the moment. In this preliminary communication, we explore the possibility of stabilizing a bNB by Brownian motion. It is shown that a fractal walk under specific conditions may leave the size of the bubble invariant. Full article
