SCTL has retracted the claimed full levitation video and the claim of full levitation. They say it was from the Lorentz force. A lone researcher on the team fooled himself and uploaded the video without checking with other members of the team. SCT lab : “I apologize for causing confusion. The last video of sample …
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, …
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 …
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. …
With Grok, @xAI is attempting to create an AI that reasons from first principles, which is fundamental if you care about getting as close to the truth as possible. The acid test would be reaching a conclusion that is correct even if it is extremely unpopular, which means being right even when the training data …
Korean news agencies have coverage of the PCPOSOS room temperature superconductor. They show all of the videos and slides including ones with full levitation and flux pinning effects. I would point out that none of the research papers that claim to falsify the room temperature superconducting claims have been able to replicate partial levitation with …
There are some people who expected more from the PCPOSOS room temperature superconductor talk. They strangely expected the team to bring the sample and show it live. BUT that is not what the abstract of the talk said. The abstract said they would show two videos of levitation and two videos of magnets. This is …
