Instantaneous application of heat in hard glassy matrices induced by electromagnetic wave or radiation can trigger the formation of nano-sized balloon structure. The starting hard matrix was prepared by the sol-gel method since that method is advantageous to render a quite slight amount of low-molecular-weight species remain in the hardened matrix. In this process, low-molecular-weight species forms gaseous species that displace the surrounding hard matrix in an isotropic geometry. As a result of that, isotropic spherical voids are ubiquitously yielded. The most marked feature of those structures is that they tend to remain as small as 100 nm at most, which indicates the suppression of the mutual coalescence of those balloon-like structures. An auxiliary work is ongoing to process those materials with the nano-sized spherical voids into fine powder. The features of the obtained powders are preliminarily investigated form those kinematical behavior.

瞬时在电磁波或辐射引起的硬玻璃基质中施加热量会触发纳米大小的气球结构的形成。启动硬矩阵是通过Sol-Gel方法制备的，因为该方法具有使少量低分子重量物种保留在硬化基质中的有利。在此过程中，低分子量物种形成气态物种，可在各向同性几何形状中取代周围的硬基质。因此，各向同性球体无处不在。这些结构最明显的特征是它们倾向于最多保持至100 nm，这表明抑制了这些气球样结构的相互合并。正在进行一项辅助工作，将这些材料与纳米大小的球形空隙一起处理成细粉。初步研究所获得的粉末的特征形式是那些运动行为。
