Bulk crystalline ices with ultralow densities have been demonstrated to be thermodynamically metastable at negative pressures. However, the direct formation of these bulk porous ices from liquid water at negative pressures is extremely challenging. Inspired by approaches toward porous media based on host–guest chemistry, such as metal–organic frameworks and covalent...

室温下多孔冰框架的形成 [化学]

具有超低密度的块状结晶冰已被证明在负压下是热力学亚稳态的。然而，在负压下由液态水直接形成这些大块多孔冰极具挑战性。受到基于主客体化学的多孔介质方法的启发，例如金属有机框架和共价...
