*In 1998/1999, a further attempt to replicate the tests of the principle was carried out by scientists Luigi Nosenzo and Luigi Cattaneo in Pavia (Italy). Again, no fusion reaction or release of energy could be established over the course of several months.<ref>Adalberto Piazzoli. "[http://www.cicap.org/new/articolo.php?id=273588 ''Fusione Fredda?

*In May 2011, US physicist Brian Ahern reported tests with a finely ground zirconium-nickel-copper alloy to which he added hydrogen gas after heating it to 500 degrees. A small rise in heat in addition to the supplied electrical heating power was observed and estimated at about 5-10 watts. A publication of the experiment is not known. Ahern's claims were only published in various blogs. Ahern has been known for a long-standing supporter of "cold fusion" which he attempts to use with a company he founded, Vibronic Energy Technologies Corp. <ref>http://www.neny.org/download.cfm/Vibronic_Energy_Technologies_Corp.pdf?AssetID=1169</ref><ref>http://www.scribd.com/doc/39076066/Vibronic-Energy-Technologies</ref><ref>From: Brian Ahern, Boxborough MA

* A group of researchers ([[Giuseppe_Levi]], [[Evelyn_Foschi]], [[Bo_Höistad]], [[Roland_Pettersson]], [[Lars_Tegnér]] and [[Hanno_Essén]] claimed to have repeated the experiment successfully in March 2014. Apparently, no ionizing radiation was detected.<ref>http://www.sifferkoll.se/sifferkoll/wp-content/uploads/2014/10/LuganoReportSubmit.pdf</ref>
