Special Issue Information

Dear Colleagues,

Radiation tolerance is critical for the safe application of materials in nuclear power generation, fusion energy, space exploration, high-energy physics experiments, and related fields. Radiation damage typically initiates with the production of Frenkel pairs. Subsequent aggregation of excess self-interstitial atoms (SIAs) and vacancies leads to the formation of secondary defects, including dislocation loops, stacking fault tetrahedra, bubbles, and voids, ultimately causing material degradation. Understanding the underlying mechanisms of radiation damage, encompassing the generation, evolution, interaction, and recovery of irradiation-induced defects, and their impact on material properties, is therefore essential.

It is with great pleasure that we announce the launch of a Special Issue entitled "Radiation Damage and Radiation Defects of Materials" in Materials. This Special Issue aims to provide comprehensive insights into the characterization of irradiated materials using neutrons, ions, electrons, and plasma.

We cordially invite you to submit your original research manuscripts for consideration in 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. 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.

Magnetic resonance techniques are powerful, nondestructive, non-invasive tools with broad applications in radiation dosimetry. Electron paramagnetic resonance (EPR) enables direct quantification of dose-dependent radiation-induced paramagnetic defects, while nuclear magnetic resonance (NMR) reflects the influence of such defects through changes in line width and nuclear spin relaxation. To date, these methods have typically been applied independently. Their combined use to probe radiation damage in the same material offers new opportunities for comprehensive characterization and preferred dosimetry techniques. In this work, we apply both EPR and NMR to investigate radiation damage in lithium carbonate (Li2CO3). A detailed EPR analysis of γ-irradiated samples shows that the concentration of paramagnetic defects increases with dose, following two distinct linear regimes: 10–100 Gy and 100–1000 Gy. A gradual decay of the EPR signal was observed over 40 days, even under cold storage. In contrast, 7Li NMR spectra and spin–lattice relaxation times in Li2CO3 exhibit negligible sensitivity to radiation doses up to 1000 Gy, while 1H NMR results remain inconclusive. Possible mechanisms underlying these contrasting behaviors are discussed. Full article
