Special Issue Information
Dear Colleagues,
For decades, explaining and coherently combining phenomena related to the transition to the amorphous glass state has been highlighted as the grand challenges of science. Despite the growing evidence of increasingly advanced research, the cognitive breakthrough has not yet occurred, and even in important respects, the situation has become even more puzzling. The fundamental attractor for researchers is probably the deep belief in the universality of the phenomenon, which manifests itself through several surprisingly similar, almost isomorphic, scaling patterns in seemingly qualitatively different systems. An example of a universalistic metric is the so-called fragility, phenomenologically categorizing non-Arrhenius changes of the primary relaxation time or viscosity, the glass transition hallmark feature.
Existing records have associated the fragility with a type of intermolecular interactions. However, it has been shown that molecular structural symmetry is at least as important. However, the question arises whether and how these molecular factors affect other universal characteristics of glass transition, e.g., orientational-translational decoupling, non-primary relaxation processes, or the emergence of non-dynamic previtreous changes, recently noted.
This special issue aims to address these problems, which are essential for the glass transition cognitive breakthrough. All submissions could cover theoretical research at the molecular level, simulation studies and experimental results.

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.
