Rare earth elements, according to the IUPAC recommendations, comprise a group of 17 elements, Sc, Y and the lanthanoids (from La to Lu). In principle, the term “rare” suggests that they are rather scarce elements, although they are actually more abundant in the Earth’s crust that some much better known elements. Thus, their abundance varies from 66 ppm in the case of Ce (an abundance similar to that of Cu or Zn) to less than 0.5 ppm in Tm (more abundant that Cd or Se). The term “rare” seems to be applied in the sense of “strange” or “extraordinary”, rather than “scarce”. For these reasons, it is not surprising the huge number of applications that all these elements have, both in bulk production industry or in minor volume applications. It has to be taken into account, as well, that most of the rare earth-containing materials with industrial applications are either oxides, or they are obtained from oxides. Regarding the bulk and mature industry applications of rare earth oxides, their use in catalysts formulations (such as in three way automotive catalysis), in glass-related industries (glass making, decolouring or colouring, glass polishing and other related applications), and permanent magnets manufacturing account for almost 70% of rare earth oxides usage. Other important industrial applications concern the metallurgy industry (used as additives in Fe or Al metal alloys), ceramics (specially in the case of Y), lighting-related applications (in the form of phosphors), as battery alloy components, or in solid oxide fuel cells, amongst others. Additionally, but not less important, there are lower scale applications, such as biomedical uses of nanoparticulated systems containing rare earth oxides for cancer treatment or as tumoral detection markers, or as sunscreens cosmetics for skin protection.
The aim of this Special Issue is to cover many of the above-mentioned applications, with a special focus on new developments for existing applications as well as the emergence of new and innovative ones. It is my pleasure to invite you to submit a manuscript to this Special Issue. Full papers, communications, and reviews will be welcome.

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 papers will be 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 2000 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.
