Dear Colleagues,

Nanoporous metallic alloys exhibit a wealth of intriguing properties compared to bulk fully-dense materials. Their ultra-high surface area−to−volume ratio, together with their low density and the possibility of hosting second-phase materials inside the porous frameworks, make these alloys useful for widespread technological applications that range from catalysts, filters, fuel cells or batteries to sophisticated platforms for drug delivery or biological labeling. The mechanical properties of these alloys (high elastic recovery, low Young’s modulus, ultra-high yield strain) foster additional functionalities for these materials, such as orthopedic implants with optimum biomechanical compatibility or nanoporous impact damper coatings with enhanced shock-resistance. This Special Issue welcomes contributions dealing with innovative strategies for synthesizing macro- (pore size > 50 nm), meso- (2 nm < pore size < 50 nm) and microporous (pore size < 2 nm) metallic alloys, such as via electrodeposition (by colloidal crystal and block-copolymer templating or by using hydrogen bubbling as a dynamic source of porosity), de-alloying, and sol-gel or nanosmelting (amongst others). Special emphases will be given to studies focusing on the control of the pore architecture, pore size distribution, and composition of the synthesized materials. Furthermore, experimental and theoretical reports that shed light on the interesting features of nanoporous metallic systems and their applications, as well as on advanced and innovative techniques for fully characterizing these type of materials, also fall within the scope of this Special Issue.

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. Metals is an international peer-reviewed open access monthly 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.
