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 …
Zhihu is very impressed by the recent claims of @iris_IGB (Iris Alexander) to have achieved 0 resistivity of #LK99 under 280K (7 Celsius). @sanxiyn fully agrees with this sentiment. Chinese observers are impressed. Iris Alexander is one of the first to replicate levitation effect in an LK99 Replication effort. IMPORTANT NOTE: There is no peer …
UPDATE: Hyun Tak Kim has put out news slides that describes a semiconductor and superconductor phase for LK99. He quoted his own paper on VO2 to explain that most researchers did not understand the difference between MIT and MST (MIT, metal to insulator transition: after cooling down, the resistivity jump → becomes very large; MST, …
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 …
The LK99 discusses CUS2 as an impurity. This would mean the original researchers are aware of CuS2 and did not make the mistake that the Beijing National Lab say was made. Plot Twist 🎤#LK99 works when there’s current flowing. This was said during the initial demo, and their patent discusses CuS2 as an impurity. In …
Princeton University has reported their research which will post to Arxiv tomorrow. They failed to get superconducting results but could not get the copper to the right lead sites. Results where the group fail to get any partial levitation are not good attempts at replication. 1. Samples following the described synthesis are multi-phase 2. Single …
A Peking University group did get some levitation in an Lk99 replication attempt. Their sample is not a superconductor. They describe the semi-levitation is the result of magnetic torque. Guo et. al synthesized #LK99 with the published methodology and matched the material composition to the original using X-Ray Diffraction. They observed levitation in the sample …
Lanzhou University researchers analysis on improving the superconducting of LK99 with more oxygen. They conclude that the hybridization between the Cu d-states of the Cu doped with the p state of the fully occupied 1/4 occupied O1 atoms may be the key for the realization of the room temperature superconductivity. In order to improve the …
People on the internet want instant gratification on the LK99 room temperature superconductor science. We can hope for this and want this but this science is difficult. I describe in these two videos how difficult but also how important LK99 science is. The positive partial results only happen in about 10% of the experiments where …
Andrew McCalip, who works on space manufacturing at Varda Space, has had the most public and possibly first replication of the proposed LK99 superconductor in the United States has made new samples. It is a larger and better sample. Will try to drop a video tomorrow. Can confirm two things. Note this is with a …
Andrew McCalip was one of the first to start on Twitter and Twitch with his LK99 replication effort. This video of the final product seems to be showing some success. It will be further analyzed. UPDATE: Andrew McCalip and another representative of Varda (space manufacturing startup) spoke with Jason Calcanis. Meissner effect or bust: Day …
