A startup, Cutting Edge Superconductors, claims to have a variant of the South Korean LK99 room temperature superconductor that shows low resistance and some weak evidence of meissner effect and quantum locking. The sample is tiny. They are trying to get a few hundred thousand in SBIR and NASA grants and $600,000 in crowdfunding. The …
China’s room temperature superconductor research continues. Here is the latest published work from the team from multiple universities and labs. This is the same teams that found stronger magnetic indications of Meissner effect in LK99 variant materials. Through heavily doping sulfur into an apatite framework, chinese researchers synthesized a new blend mainly comprising variant apatite …
Copper-substituted lead apatite, aka LK-99, was claimed to be room-temperature superconductor, but due to the complicated components and structures, the reproduction is still controversial. Chinese researchers have some replication of the Korean work and have extended with better procedures and research. They have updated a prior paper with new synthesis (instructions about how to make …
The pursuit of room-temperature superconductivity has long been a holy grail in the field of condensed matter physics because it could revolutionize all electricity based technologies and in particular make computers at least hundreds of times faster. In mid-2023, the Korean LK-99 (copper-substituted lead apatite) material provided a controversial possibility of a major breakthrough. Researchers …
Two weeks ago the Korean group presented new room temperature superconductivity research and this week the Chinese research group published new research on LK99 type superconductors. Are we at a breakthrough? What has been done in this new research? China has published new research on improved copper and sulfur codoped material with a stronger meissner …
Chinese researchers are making variations of LK99 room temperature superconductor materials with more sulfur and copper in the chemistry. They are publishing results with stronger magnetic indications of a Meissner effect. The chinese researchers have been online discussing their room temperature superconducting research and the challenges of the materials. Here are the issues discussed. * …
Chinese researchers have published a new non-peer reviewed paper on their sulfur copper doped led apatite room temperature superconductor. They have increased the Meissner effect signal. Supplemental material from the China researchers. This describes the precise work done show they did not make measurement errors. Background Context In mid-2023, the Original Korean researchers discovered the …
There was a APS presentation by Ulsan Korea University researchers. It is being reported that numerous comments on the Chinese website Zhihu imply that the University of Ulsan’s data plot is so important that a certain superconductivity expert saw the decisive signal proving LK99’s superconductivity in the graph’s temperature rise curve near 200K. Nextbigfuture does …
This is a review of the arguments and evidence for and against LK99 type materials as room temperature superconductors. Case Against Cuprous Sulfide and Iron Contamination The claims against LK99 and LK99-variants materials as a superconductor is that cuprous sulfide has some transition temperatures that match up with some of the bulk LK99 readings. They …
SCT Corp is a different South Korean group from the original Korean team working on room temperature superconductors. Dae-Chel Jung is one of the researchers are SCT Corp. SCT Corp provided a video of one of their superconducting samples fully levitating. SCTL is short for Superconducting Technology Lab and SCT Corp is Superconductor Technology Corp. …
The original south korean team of researchers presented new videos of their work on room temperature superconductors on Monday. In this video, I (Brian Wang) discuss what I think are the main points from the brief 10 minute update. There is now full levitation of the new material which has sulfur in the chemical formula. …
