Special Issue Information
Dear Colleagues,
In recent years, various industries have been looking for new materials, the use of which would significantly affect indicators such as the production costs, competitiveness, labor productivity, operation, ecology, and innovation. One of the very interesting, relatively new groups of materials are materials with an amorphous and nanocrystaline structure. The first of these are single-phase materials and are characterized by the presence of short-range interactions between atoms and the lack of periodicity in their spatial arrangement. The latter are two-phase materials consisting of an amorphous and a crystalline part. The mixture of these two phases may be the cause of a significant improvement in the functional properties of the tested alloy in relation to the properties of an amorphous or crystalline alloy of the same chemical composition.
Materials with an amorphous and nanocrystaline structure are one of the newer groups of modern materials with significantly better properties than the corresponding crystalline materials of the same composition. Particularly interesting, for functional reasons, are amorphous ferromagnetic alloys showing the so-called soft magnetic properties. These materials, compared to the commercially used FeSi transformer sheets, show significantly lower losses during re-magnetization, reducing this undesirable effect by as much as 80%. Therefore, in-depth knowledge of the methodology of their production and a detailed analysis of the magnetic properties with the simultaneous study of their structure may contribute to significant technological progress.
Another group of modern materials are geopolymers. The term includes modern inorganic, amorphous, synthetic polymers aluminum silicates with a specific composition and unique properties.
This Special Issue covers all aspects of the synthesis, characterization, and application of modern amorphous and nanocrystaline materials. I am inviting you to publish the results of your research related to the subject of this 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.
