We report on the magnetic and structural properties of Co-doped ZnO nanoparticles prepared by the vaporization-condensation method in a solar reactor. X-ray diffraction data and high-resolution electron microscopy (HREM) confirm the total absence of metallic Co clusters or any other phase different from würtzite-type ZnO. [...]

The field-amplitude Hm and circular frequency ω dependent ac susceptibility, χ=χ'−jχ'', of a hard superconducting cylinder with flux-flow type current-voltage characteristic is calculated. A remarkable feature of the resultant χ(Hm,ω) is that both the maximum χ'', χ''m, and dlgHm(χ''m)/dlgω increase with increasing ω. [...]

Several breakdown events and multilevel current fluctuations have been observed when ultrathin SiO2 films are subjected to constant-voltage stresses. These breakdown events are sometimes reversible, and consist in a local change of conduction mechanism. [...]

We report the shock-wave synthesis at a yield ≳80% by volume of the single copper layer thalliumsuperconductor of composition Tl2Ba2CuO6. The as-synthesized material displays zero resistance near 55 K and a diamagnetic onset to bulk superconductivity at 70 K. [...]
