A team of scientists from the Physics Department of Southeast University, a top university in Nanjing, China, have reported measuring 0 resistance in a sample of LK-99 they synthesized from scratch. Claimed to have synthesized LK-99 and to have measured superconductivity up to a temperature of 110 kelvin. Claimed to have observed an abrupt drop …
Another Density Function analysis of LK-99 proposed room-temperature superconductor by researchers at Northwest University in China and Tu Wien Austria Physics Institute. They think superconductivity might be possible, but only if LK-99 is doped, and that diamagnetism without superconductivity is unlikely. Liang Sia,b and Karsten Heldb a School of Physics, Northwest University, Xi’an 710127, China …
Sinéad Griffin, Berkeley Lab researcher, published the simulation of LK99 paper. The paper did *not* prove nor give evidence of superconductivity in Cu-apatite. It showed interesting structural and electronic properties that have features common with high-Tc superconductors provided Cu is in the right place. Result 3: The electronic structure of Cu on the Pb(2) does …
The Condensed Matter Theory Center still needs to see conclusive LK99 Superconductivity evidence. The situation is promising and hopeful but we are not definitively in the age of room temperature superconductors yet. Several groups have made LK99, most impressively in a 'garage' in LA under live streaming, here is the first arXiv-posted 'synthesis', but these …
I, Brian Wang, spoke with Randy Kirk about the room temperature superconductor developments and the future of energyo srand electric cars and trucks. Randy asked me about Elon Musk comments about his predicted future shortages. “My prediction is that we will go from…an extreme silicon shortage today to…an electricity shortage in two years,” Musk said …
Derek Lowe in the Journal Science is guardedly optimistic at this point. The Shenyang and Lawrence Berkeley calculations are very positive developments. This is by far the most believable shot at room-temperature-and-pressure superconductivity the world has seen so far, and the coming days and weeks are going to be extremely damned interesting. The Fermi level …
Another levitating flake of LK-99 superconductor from China. A third levitating LK-99 superconductor replication video has dropped from China https://t.co/mCewSbYD9X Caveat here is that they then measured the resistance and found it to have high resistivity, so more work needs to be done to get both levitation + zero resistance samples pic.twitter.com/Q6OTDjaReI — Floates0x (@floates0x) …
Under the guidance of Professor Chang Haixin, postdoctoral Wu Hao and doctoral student Yang Li of the School of Materials Science and Technology of Huazhong University of Science and Technology they have successfully verified and synthesized the LK-99 crystal. It can be magnetically levitated for the first time and this is shown on a bilibili …
Sabine Hossenfelder predicted that the first superconducting replications will fail and then we will never hear of LK-99 and doped Larkanite superconductors again. Sabine predicts first published replication attempts for making superconducting LK99 would be failures. This was correct.The first two published experimental replications from India and China were negative (aka they did not find …
Lawrence Berkeley National Lab simulated this using heavy-duty compute power from the Department of Energy, and looked to see what would happen to the ‘electronic structure’ of this material, meaning, what are the available conduction pathways in the material. It turns out that there are conduction pathways for electrons that are in just the right …
