English(EN) Experiment shows liquid metal TIM doesn’t dry out; it turns solid

研究发现液态金属TIM会固化，不会变干

一项为期两年的电子显微镜实验显示，液态金属导热界面材料（TIM）并不会像人们普遍认为的那样变干。相反，TIM中的镓会与铜发生反应，形成一种称为CuGa2的固体化合物。这种固体层的导热性约为纯铜的四分之一。当应用于镀镍散热器时，类似的反应会形成NiGa5，它更薄但导热效果不如铜镓化合物。 AI

本文如何被排名

Signal score: 0 / 100; Composite score across the factors below. Higher = stronger signal that this story matters right now.
Newsworthiness bucket: Tool; 该集群详细介绍了关于特定材料行为的科学实验结果。[lever_c_demoted from research: ic=1 ai=0.1]
Source corroboration: Single-source cluster; Only one publisher covered this so far. Single-source stories can still rank when the publisher is high-authority, but they lack cross-source corroboration.
Topics: product, other; Editorial topic classification. Feeds into how the story surfaces on /topic/<slug> hub pages and into the per-entity coverage mix.
AI-industry relevance: Low; Off-topic or adjacent — cluster remains reachable but doesn't surface in AI-industry rankings.
Story freshness: 1 days old; Coverage has settled into its steady-state source set.
