Present-day volume prices of HTSs (high temperature superconducting) wire and tape range from $150 to $200/kA-m (kiloAmps per meter). Many analyses of the commercial viability of superconducting applications show that a conductor cost of $50/kA-m (kiloAmps per meter) is the tipping point for widespread application for electric power use. Jun 2023, Journal Science The prospects …
Kings College of London and University of Colorado researchers looked at LK99 by going beyond density function theory analysis with a different analytic approach. They looked at electron and hole doping, within the QSGW (quasiparticle self-consistent GW ) framework. They conclude that while LK99 might or might not be superconducting, it has interesting properties that …
Indian researcher, VPS Awana, says that using Scanning Tunneling Microscopes, that samples of LK99 possibly room temperature superconducting material could have superconductivity measured. Scanning Tunneling Spectroscopy systems cost about $20,000 to $200,000. They are common and such systems are in India and at Universities and companies around the world. This will only work on LK99 …
The original LK99 team reassures the world that LK99 superconductivity is real and was demonstrated. They will provide evidence and answers in the next published paper. They recommend other researchers need to have patience and try harder (and implied is to work with the original Korean team) because the others will also make it superconduct. …
Doped lead apatite has been recently reported to feature superconductivity at room temperature and ambient pressure, which may have huge impact on the progress of the humanity in general. Bulgarian researchers performing quantum chemical calculations support the one dimensional superconductivity case. Georgi N. Vayssilov,* Petko St. Petkov,* Hristiyan A. Aleksandrov Faculty of Chemistry and Pharmacy, …
Iris Alexander had the first publicly claimed LK99 levitation and now has claimed to have low resistance at about 7 degrees celsius. She is giving her ingredients and pictures of her samples. The ingredients (MOLAR %) – 23,5% PbSO4; – 70,5% PbO; – 3,5% Cu3P; – 2,5% PbSiO3. Cooled reasonably fast, crystalline structure should be …
There is an online comic in korean that explains why the LK99 superconductor is so hard to make. @8teAPi has the translation. Translated from the excellent comic here: if anyone knows author please ask them to get in touchhttps://t.co/9SSwA8EFqe — Ate-a-Pi (@8teAPi) August 17, 2023 Why SuperConductor So Hard? – take a bunch of Lead, …
An article in Nature, says making conclusive statements about LK-99’s properties is difficult, because the material is finicky and samples contain varying impurities but then goes on to make conclusive statements that LK-99 claims were wrong. In their preprint, the Korean authors note one particular temperature at which LK-99’s showed a tenfold drop in resistivity, …
Physics World reports that LK99 produced by the descriptions in the original papers are not superconducting and not room temperature superconducting. A deep investigation of the original samples is needed to confirm any hints of superconducting observations and then to find any very specific impurity that is unique to the Korean samples. The original LK99 …
Two updates on LK99. The Indian scientist who got LK99 sample replication on his third try says that his new sample is not superconducting. One of the original LK99 team responded with the description of two phases of LK99 (semiconductor and superconductor). New Facebook Posting from Indian Scientist Awana VPS – LK99 CSIR-NPL (INDIA) LK-99 …
VPS Awana has been trying for weeks to get a good LK99 replication. He has been in direct contact with the Korean team. He published two arxiv preprints talking about how his previous samples didn’t work. NEW most promising replication yet: The National Physics Lab New Delphi, led by VPS Awana, has finally succeeded in …
