      Adaptive VN/Ag nanocomposite coatings with lubricious behavior from 25 to 1000 °c 

      Aouadi, S. M.; Singh, D. P.; Stone, D. S.; Polychronopoulou, K.; Nahif, F.; Rebholz, Claus; Muratore, C.; Voevodin, A. A. (2010)
      A two-phase nanocomposite coating that consists of inclusions of silver in a vanadium nitride matrix (VN/Ag) was investigated as a potential adaptive coating with a reduced friction coefficient from 25 to 1000 °C. This ...

      Resistive switching phenomena in Li xCoO 2 thin films 

      Moradpour, A.; Schneegans, O.; Franger, S.; Revcolevschi, A.; Salot, R.; Auban-Senzier, P.; Pasquier, C.; Svoukis, E.; Giapintzakis, John; Dragos, O.; Ciomaga, V.-C.; Chrétien, P. (2011)
      A substantial resistive switching of Li xCoO 2 mixed-conductor thin films is observed for the first time. The occurrence of possible bipolar switching in these oxide thin films is by current-voltage curves, investigated ...

      Vibrational and electronic anomalies near Tc in tetragonal superconducting YBa2(Cu0.9557Fe0.05)3O7.1 

      Kimball, C. W.; Matykiewicz, J. L.; Lee, H.; Giapintzakis, John; Dwight, A. E.; Dunlap, B. D.; Jorgensen, J. D.; Veal, B. W.; Fradin, F. Y. (1988)
      Mössbauer effect studies have been made as a function of temperature for the orthorhombic (χ=0.01, 0.02) and tetragonal (χ=0.05) superconducting compounds YBa2(Cu1-χ57Feχ)3O7 + y. For Fe in or slightly displaced from the ...
