Impurities Affect Superconductive Material Performance (image) North Carolina State University Share Print E-Mail Caption Research from North Carolina State University finds that impurities can hurt performance -- or possibly provide benefits -- in the key superconductive material Bi2212 (shown here), which is expected to find use in a host of applications, including future particle colliders. The size of the impurities determines whether they help or hinder the material's performance. Credit Golsa Naderi Usage Restrictions Image credit must be given.
