近期,美国罗切斯特大学的物理学家Ranga Dias因其在超导领域的新发现再次成为媒体关注的焦点。早在三月份,他的研究成果曾在美国物理学会会议上引起轰动,宣布发现了一种名为亚氨基镥(LuNH)的氢化物,据说在1GPa、21摄氏度下具有超导特性。然而,这项发现很快引起了广泛的质疑。

实验复现失败、作者不肯透露产物制备细节等问题使得人们对这种新材料是否真正具有超导特性产生了怀疑。此外,Dias的学术丑闻也可能影响了人们对他的研究的信任。据报道,Dias的博士论文涉嫌抄袭,而且他的另一篇发表在Physical Review Letters上的论文也被指控数据造假。虽然罗切斯特大学对这两起事件进行了调查,但没有找到确凿证据支持这些指控。

尽管Dias坚持认为自己的研究结果是正确的,但他的研究仍然受到了广泛的关注和质疑。这不仅是因为他的研究发现引起了媒体的广泛关注,还因为他过去的研究经历和他目前的研究成果之间存在的一些疑问。

这种争议性可能进一步加剧了科学家们对Dias的研究的谨慎态度,因为他们在试图重复他的实验时遇到了困难,而且在理论层面上也没有观察到室温超导的迹象。这些都可能会影响到人们在未来的研究中对这个领域的信心。
