Aqueous methylcellulose is an “abnormal” inverse-freezing fluid, which gelates when heated. We ventured to stimulate this phase-transition by mechanical impact, whose resulting shockwaves and local heat could be uptaken by the endothermic gelation. High-speed photography was used to observe this transition in microsecond timescales. This phenomenon enables attenuation of shockwaves.

甲基纤维素水溶液中的冲击诱导凝胶化†

甲基纤维素水溶液是一种“反常”的反向冷冻液体，在加热时会发生凝胶化。我们冒险通过机械冲击来刺激这种相变，其吸热凝胶可以吸收其产生的冲击波和局部热量。高速摄影用于以微秒为单位观察这种过渡。这种现象使冲击波衰减。
