After facing multiple challenges, chinese researchers have discovered a new material that exhibits room temperature superconductivity with unexpectedly low resistivity. Their findings challenge the understanding of superconductivity and point to new possibilities for applications in energy, transportation, and computing.

In the world of physics, there is one phenomenon that continues to vex scientists: room temperature superconductivity. This elusive state of matter, where electrical resistance disappears at temperatures above -238 degrees Fahrenheit, has been a subject of intense research for decades. And now, a team of chinese researchers may have just taken a significant step towards unlocking its secrets.

The team, led by Mr. Guan, has been actively discussing their research on the online forums. They have been studying a new material that shows potential for room temperature superconductivity. However, the researchers have faced multiple challenges in their experiments. The most significant one being the small current of their material, which makes it almost impossible to stabilize.

The sample used for the experiment is a pile of powder that is simply pressed into pieces with a mold. This crude method is a far cry from the industry standards for creating conductive films that require purification, polishing, and flattening. Yet, even with these less sophisticated experimental conditions, the researchers were surprised to find that the conductivity of the material is almost equal to that of ordinary graphite. This unexpected result shook their understanding of superconductivity.

Mr. Guan and his team are now working on understanding exactly how their material is exhibiting room temperature superconductivity. The researchers believe that the actual conductive channels are only concentrated near the surface of the sample, which would explain the low resistivity observed. This challenges the belief that the material is a one-dimensional superconductor, as previously thought. The team's one-dimensional theory is almost ruined, and they have to re-examine their entire understanding of this phenomenon.

Nextbigfuture, a leading science and technology blog, suggests that the chinese researchers may have discovered a new type of superconductor that defies current theories. They base this hypothesis on the researchers' estimation of resistivity based on the thickness of the entire block, as well as other factors. The researchers, however, remain steadfast that their material exhibits room temperature superconductivity, and they are determined to eliminate other possible explanations one by one.

To understand the resistance of their material better, Mr. Guan had to consider several alternative explanations. Some of these included complex magnetism, transparent single crystal, and cuprous sulfide. These alternatives were suggested by various critics of the research. However, Mr. Guan was quick to dismiss these claims, stating that their data is accurate and that their findings cannot be explained through other means. The researchers are confident that they have a ground-breaking discovery in their hands and are determined to prove it.

In their quest to eliminate other explanations, the team has also faced challenges with accurately measuring the resistance of their material. The material's unique properties make it difficult to absorb and release heat, resulting in a temperature difference between the actual temperature and the test set temperature. Therefore, the measured resistance is not a completely straight line, and the value given in the text was recorded at a heating rate of 3K/min.

To provide further evidence for their findings, Mr. Guan got a third party to test the material at a heating rate of 5K/min, and the results have been included in the supplementary information. Additionally, the researchers have also recorded a straight resistance line at a heating rate of 1K/min, which is another crucial piece of evidence that supports their claim.

Overall, the chinese researchers' latest findings have opened up new possibilities in the study of superconductivity. They have shown that, with the right material and experimental conditions, room temperature superconductivity might not be as elusive as previously thought. This could have significant implications in various fields such as energy transmission, transportation, and computing. The road to fully understanding and harnessing the potential of room temperature superconductivity may still be long, but the chinese team's latest breakthrough has brought us one step closer.
