This discovery builds on the 1987 Nobel Prize-winning research on copper oxide superconductors but goes beyond copper, offering a new avenue for high-temperature superconductivity.<\/p>\n\n\n\n<p class=\"\"><em>Superconductivity<\/em> is a phenomenon where a material can conduct electricity with zero resistance, meaning no energy is lost as heat. This property could revolutionize electronics, making devices more energy-efficient. However, most superconductors only work at extremely low temperatures, making them impractical for everyday use. The 1987 Nobel Prize-winning discovery of copper oxide superconductors, which work at temperatures above 30 K, sparked extensive research into materials that could exhibit superconductivity at higher temperatures.<\/p>\n\n\n\n<p class=\"\">The NUS team\u2019s breakthrough material, made from nickel oxide, demonstrates that superconductivity can be achieved without copper. By synthesizing (Sm-Eu-Ca)NiO\u2082, a nickel-based oxide, the researchers confirmed that this material could reach superconducting temperatures above 30 K, similar to copper-based materials, without requiring additional pressure or cooling methods. This result shows that high-temperature superconductivity is not exclusive to copper, offering a broader range of elements in the search for new superconducting materials.<\/p>\n\n\n\n<p class=\"\">This discovery, whose results were published in <a href=\"https:\/\/www.nature.com\/articles\/s41586-025-08893-4\" target=\"_blank\" rel=\"noopener\" title=\"\"><em>Nature<\/em><\/a>, opens up new possibilities for future research and applications. By continuing to explore the unique properties of these materials, the NUS team hopes to develop even higher-temperature superconductors. These materials could be crucial for creating more efficient electronics and energy systems with real-world applications, from medical imaging to energy storage. The findings also offer valuable insights into the fundamental science of superconductivity, potentially reshaping the future of modern technology.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 id=\"references\" class=\"wp-block-heading\">References<\/h1>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"\">National University of Singapore.
