The search for new materials with good performance that are also sustainable for the environment requires a suitable combination of advanced methods to understand their structural features, from macro- to nanoscales. Among the techniques able to supply information about the properties of a material at an atomic level, positron annihilation offers several advantages: it is non-destructive and is able to detect sub-nanometric cavities, such as vacancies in metals, voids in porous materials, and free volume holes in polymers. Furthermore, using a beam of monoenergetic positrons, it is possible to explore different subsurface layers of material.
The aim of this Special Issue is to collect reviews as well as original research articles on this technique, showing its capability to potentially investigate any kind of material, from metals to semiconductors and non-metallic systems.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.
