Scientists use unconventional spark plasma sintering method to prepare highly dense superconducting bulk magnesium diboride with a high current density. Spark plasma sintering (SPS) is a process that uses high-pressure and pulsed electric current to turn powders into dense solids. In a recent study, a team of researchers used SPS to prepare bulk magnesium diboride […]

Researchers develop an optimized recipe for retaining superconductivity in bulk MgB2 by enhancing its critical current density. Magnesium diboride (MgB2) superconductors show great promise for large-scale applications. However, its critical current density (the current density above which superconductivity vanishes), Jc , at high magnetic fields in bulk form is not sufficiently high. An international research team has devised

Researchers improve the performance of superconductors while reducing the cost using a novel refining technique for boron. Magnesium diboride (or MgB2) ceramic superconductors have garnered interest owing to their ease of fabrication, light weight, and low cost. However, a cheap and efficient technique for boron refinement is required before MgB2 superconductors can be produced widely

Mica, a well-known insulator, has been found to behave as a semiconductor when thinned down to a few molecular layers. Muscovite mica (MuM) is a highly stable mineral that is commonly used as an insulator. However, the electrical properties of single-layer and few-layered MuM are not well understood. Now, a group of researchers from Japan
