Special Issue Information
Dear Colleagues,
In recent years the use of anodization as a means of nanopatterning valve metal surfaces has been extended in the range of treated metals, moving from the standard aluminium substrates and relatively common titanium ones to more unusual metals such as zirconium, tantalum, niobium, and hafnium. Even alloys of these or other metals, including copper, tin, and zinc, have been used in the attempt to modulate the resulting properties of the porous surface coating. The applications of the micro-nanoporous surfaces resulting from anodization are diverse: from optical ones, where the ordering of pores positions or at least their monodispersity in size are critical to give rise to diffraction or cavity effects for photonic crystals and sensors or for distributed feedback lasers, respectively; to drug delivery, where the response to diffusion in/out of the pores is critical; to scaffolds and/or permanent implants in orthopaedic or dental fields, where functionalization of the pore wall surfaces and even structure interiors is key to provide the best possible biocompatibility and bioactivity; on to visible-light-sensitive photocatalysts, after doping the oxide layer. Sensing applications could be based on the SERS effect or interference in reflectance/transmittance spectroscopy. The expansion of the use of porous oxides as templates for the lithographic fabrication of advanced materials in still other possible areas (e.g., catalysis, separation, energy) will be additionally considered.
This Special Issue would like to collect contributions from all these diverse areas, especially pointing to use of new metals to be oxidized, in order to provide a picture of the current state-of-the-art in the field. Manuscripts on the fabrication, characterization, and applications of the structured materials surfaces—in the form of both coatings and membranes—will be welcome.
The relevant topics include but are not limited to those listed under the Keywords section below.

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.
