New video from SCTL Korea room temperature superconductor experimenters claimed to shows a very strong full levitation effect. Full levitation would be evidence of the Meissner effect found only in superconductors. I have shown how the levitation evidence was originally partial levitation. Critics says partial levitation can be from diamagnetics or even some iron contamination. …
Investigation of the zero resistance and temperature-dependent superconductivity phase transition in Pb-Cu-P-S-O compound by Huk Geol Kim, Dae Cheol Jeong and Hyun-Tak Kim. Hyun-Tak Kim is one of the lead researchers for the LK99 team. This new paper presents a specific critical temperature for PCPOSOS, demonstrating consistency with the original authors’ data. In this study, …
The performance of superconducting microwave circuits is strongly influenced by the material properties of the superconducting film and substrate. While progress has been made in understanding the importance of surface preparation and the effect of surface oxides, the complex effect of superconductor film structure on microwave losses is not yet fully understood. In this study, …
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 …
SCT Lab published a paper on how they make the Pb-Cu-P-S-O compound that has some pieces with potential room temperature superconductivity. The description of the process to make it is partial. How they get the powders is not described. They did not give mass ratios (cited intellectual property). The testing process for zero resistivity did …
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. …
