A pair of Indian scientists may have just discovered the first superconductor material that works at room temperature. Their finding – which is currently surrounded by controversy – comes ten months after they were admonished by their peers because of a lack of evidence to support their findings.
The Indian Institute of Science (IISc), Bengaluru researchers have pre-published their research for review in arXiv, with the backing of eight more researchers and plenty more evidence a second time, and the final verdict is still weeks away.
The pair of IISC scientists that came out with the new research studied nanostructured materials as potential superconductors. When seen under a microscope, nanomaterials have a structure that is only a few nanometers (nm) is size, typically under 10 nanometres. The researchers used nanomaterial in the form of pellets and films made from silver particles that are embedded into matrix of gold atoms. This material, as it turns out, is a "superconducter" of electricity at ambient or room temperature.
The study came under fire when first published in 2018 was a pattern of "noise" that appeared in their data. All experiments have some degree (even if negligible) of noise, which is discounted if the data largely support what the research claims. But in the case of the current study, the noise also appeared in controls (the set-up for the experiment itself). The researchers argue that the noise appeared randomly, and was nearly impossible to duplicate by changing a parameter here and there.
They are not sharing their samples as silver can tarnish in presence of air which would lead to a huge damage in such a monumental result.
I want to know all about the noise that appeared in all the research papers published till now(regarding this experiment)?
Is the noise appearing in the experiments is just due to some instrumental operations or is it related to some magnetic phenomenon and superconductivity?Please explain the physics of the noise appearing in the situation.
