Special Issue Information
Dear Colleagues,
Solid-state Nuclear Magnetic Resonance (NMR) spectroscopy is one of the most useful experimental techniques for the investigation of local structures in minerals and crystalline solids, as well as glasses and amorphous materials, polymers, materials for energy, etc. in different order-disorder states and solid-solution series. The data produced by NMR spectroscopy provide an alternative and complementary study in the characterization of the solid state, in relation to reciprocal space techniques. While diffraction techniques can determine long-range atomic order as periodicity following the conventional lattice model, NMR techniques can also investigate short-range and medium-range polyatomic order schemes, not only in ordered compounds but also in minerals with low crystallinity and also in non-crystalline compounds, including alkali feldspars, plagioclases, micas, clay minerals, amphiboles, zeolites, etc. NMR mineralogy has been the subject of intense research throughout the 20th century for many minerals. However, new methodologies are now derived from much more modern technological innovations, and therefore, new methods have been developed for the study of atomic coordination, spectroscopically distinct crystalline sites, order and disorder phenomena, atomic mobility, and the role of protons in various structural configurations, as water molecules and as –OH groups, including minerals with paramagnetic impurities, with more detailed capability than ever before. Therefore, the NMR technique is opening a new possibility to describe and explain the nature of the solid state, in a complementary approach to that of synthetic materials, based on the local configurations of atoms that develop or do not develop extended periodic structures. From this new structural model, an investigation into the natural diversity of the crystalline structures of minerals can be derived, such as NMR Mineralogy.

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. Minerals 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 2400 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.
