Between solid and liquid: New type of structural transformation has been observed in a model of methane molecules adsorbed in micropores of the IRMOF-1 metal–organic framework (MOF). The mechanism of the transformation is defined by a probability distribution function. The methane structure in the pore is characterized by limited mobility, and represents a new state of matter, intermediate between solid and liquid.

吸附诱导的纳米孔结构相变

在固体和液体之间：在吸附于IRMOF-1金属-有机骨架（MOF）的微孔中的甲烷分子模型中，观察到了新型的结构转变。转换的机制由概率分布函数定义。孔中的甲烷结构以有限的迁移率为特征，代表了介于固体和液体之间的一种新的物质状态。
