Help with Very High Temperature superconductors (28°C )

In summary, researchers have recently published results about Very High Temperature Superconductors (VHTSC) on www.superconductors.org. However, there is confusion about the meaning of "10 dB environmental noise" and the reliability of the results. Some experts believe that the results are not trustworthy due to the poor positioning of the 4 point contacts and the use of resistivity as an indicator for superconductivity. It is suggested that magnetization measurements be used instead. Additionally, it is possible that the results could be due to something mechanical or a different kind of phase transition. It is also recommended that the researchers conduct further experiments, such as grinding their crystal into a powder and observing its behavior around a magnet.

Help with Very High Temperature superconductors (28°C!)

Since several months researchers on www.superconductors.org have published results about Very High Temperature SuperConductors (VHTSC).

A new result has been recently published:
http://www.superconductors.org/28c_rtsc.htm

I don't understand what they mean by "10 dB environmental noise", can anybody explain?
Are their results reliable?

The results are complete and utter junk. Resistivity is a poor indicator of superconductivity unless it really drops to zero. The positioning of their 4 point contacts on the picture is very poor, and if they want to show anything, magnetization measurements would be the way to do it. What they show could be due to something mechanical that changes for example, or really a phase transition of a very different kind.
Furthermore, if they do have a sizeable volume fraction of a room temperature superconductor, they could grind their crystal into a powder poor it over a magnet and see little particles hovering in the air.
 

1. What are Very High Temperature superconductors and how do they differ from traditional superconductors?

Very High Temperature (VHT) superconductors are materials that exhibit superconducting properties at temperatures above -196°C, which is the boiling point of liquid nitrogen. This is significantly higher than traditional superconductors, which require much lower temperatures, close to absolute zero. This makes VHT superconductors more practical and cost-effective to use in various applications.

2. How are VHT superconductors created?

VHT superconductors are typically created by mixing different elements and compounds together in specific ratios, and then subjecting them to extreme heat and pressure. This process alters the atomic structure and creates a material with superconducting properties at higher temperatures. Researchers are constantly experimenting with different combinations and techniques to create new VHT superconductors with even higher temperatures.

3. What are the potential applications of VHT superconductors?

VHT superconductors have a wide range of potential applications, including in energy storage and transmission, medical imaging and diagnostics, and transportation. They can also be used in high-speed computing and communication technologies, as well as in advanced technologies such as fusion reactors and levitating trains.

4. What are the challenges in working with VHT superconductors?

One of the main challenges in working with VHT superconductors is their brittleness. These materials are often difficult to handle and require special techniques to shape and mold them into usable forms. Additionally, VHT superconductors are still relatively new and not fully understood, so researchers are still working to optimize their properties and find ways to mass-produce them at a lower cost.

5. How can VHT superconductors benefit society?

VHT superconductors have the potential to greatly benefit society by improving energy efficiency, reducing carbon emissions, and enabling new technologies and advancements in various industries. For example, the use of VHT superconductors in power grids could lead to more efficient and reliable energy transmission, while their use in transportation could reduce fuel consumption and emissions. The medical field could also benefit from VHT superconductors through improved diagnostic tools and treatments.
