论文摘要
玻璃科学的最新突破是通过物理蒸气沉积技术合成了超高的眼镜。这些样品显示出增强的热力学，动力学和机械稳定性，对基本科学和技术应用具有重要意义。但是，蒸气沉积技术仅限于原子，聚合物和有机玻璃形成剂，并且只能生产薄膜样品。在这里，我们提出了一种新颖的方法，可以通过随机粒子键合在散装中产生超高的玻璃构型，并使用计算机模拟我们表明，这种方法确实允许产生超高的玻璃。我们的技术原则上适用于任何分子或软物质系统，例如具有可调键相互作用的胶体颗粒，因此为大型超强玻璃的设计开辟了道路。
A recent breakthrough in glass science has been the synthesis of ultrastable glasses via physical vapor deposition techniques. These samples display enhanced thermodynamic, kinetic and mechanical stability, with important implications for fundamental science and technological applications. However, the vapor deposition technique is limited to atomic, polymer and organic glass-formers and is only able to produce thin film samples. Here, we propose a novel approach to generate ultrastable glassy configurations in the bulk, via random particle bonding, and using computer simulations we show that this method does indeed allow for the production of ultrastable glasses. Our technique is in principle applicable to any molecular or soft matter system, such as colloidal particles with tunable bonding interactions, thus opening the way to the design of a large class of ultrastable glasses.
