Abstract

Minkowski functionals were used to study the geometry of helium solubility sites in low-density silica glasses. The study revealed that helium superdiffusion in these glasses is associated with the formation of large, branched solubility sites whose channels extend across significant regions of the glass. These sites are characterized by a high mean breadth but exhibit low relative volume and surface area.

低密度硅玻璃中氦溶解度的几何结构

利用闵可夫斯基泛函研究了低密度硅玻璃中氦溶解度的几何结构。研究表明，氦在这些玻璃中的超扩散与形成大的分支溶解度位点有关，其通道延伸到玻璃的重要区域。这些地点的特点是平均宽度大，但相对体积和表面积小。

期刊介绍： The Journal of Non-Crystalline Solids publishes review articles, research papers, and Letters to the Editor on amorphous and glassy materials, including inorganic, organic, polymeric, hybrid and metallic systems. Papers on partially glassy materials, such as glass-ceramics and glass-matrix composites, and papers involving the liquid state are also included in so far as the properties of the liquid are relevant for the formation of the solid. In all cases the papers must demonstrate both novelty and importance to the field, by way of significant advances in understanding or application of non-crystalline solids; in the case of Letters, a compelling case must also be made for expedited handling.
