Special Issue Information

Dear Colleagues,

Various remediation techniques are available to prevent pollution episodes originating from effluents. Among these techniques, adsorption has attracted scientists’ attention, particularly in recent decades, with intense work being conducted in the production of cost-effective adsorbents. Sorption processes consist of the sequestration of one or more species of interest on the surface of a solid, known as a sorbent. Being a surface phenomenon, it is clear that nanosorbents can constitute the next step in the research of sorption. Nanoparticles, for which surface interactions are enhanced, owing to the large surface/volume ratio of these systems, can be considered the definitive evolution in the development of sorbents. However, the practical manipulation of nanosorbents, subsequent separation after sorption, and the possibility of the regeneration of nanosorbents are still limitations that need to be fully explored. In this Special Issue, the state of the art in nanosorbents for metal and/or dye pollution remediation will be analyzed.

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 2900 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.
