The Journal of Non-Crystalline Solids publishes review articles, research papers, and Letters to the Editor on oxide and non- oxide glasses, amorphous semiconductors, non-crystalline films such as those prepared by vapor-deposition, glass ceramics and glassy composites. Papers on the liquid state are also included in so far as the properties of the liquid are relevant for the formation of the solid. The journal publishes "Letters to the Editor" with a guarantee of publication within 3 months after acceptance of the manuscript.
