Special Issue Information

Dear Colleagues,

High-entropy alloys (HEAs) are near-equimolar alloys comprising five or more elements. In recent years, HEAs have been drawing increasing attention from both theoretical and experimental perspectives, as the high degree of synergy therein leads to high entropy, lattice distortion, sluggish diffusion, and the cocktail effect. Although the mechanical properties of HEAs have been extensively investigated at the beginning, their application as functional materials, such as catalysts, has only recently been probed. The active surfaces of HEAs consist of millions of different possible atomic arrangements, and some surface sites may have optimal properties that can overcome the limitations of current catalysts.  However, grand challenges exist; (i) the controlled and efficient synthesis technique for targeted multi-elemental compositions; (ii) identification and understanding of the active sites through precise surface characterization; (iii) fundamental studies of surface dynamics under catalytic conditions.  The data-driven strategy and high-throughput experiments are also desired to assist in further element optimization over high-dimensional composition space.

This Special Issue is dedicated to providing the basis for designing high-entropy nanomaterials (not limited to alloys) with diverse compositions and structures, also providing unprecedented opportunities for element selection for fabricating a desired catalyst for various applications/reactions.

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.
