The relationship between the cuprate pseudogap (Δ(p)) and superconducting gap (Δ(s)) remains an unsolved mystery. Here, we present a temperature- doping-dependent tunneling study of submicron Bi(2)Sr(2)CaCu(2)O(8+δ) intrinsic Josephson junctions, which provides clear evidence that Δ(s) closes at temperature T(c) (0) well above transition but far below opening T*. We show pairing first occurs predominantly on limited Fermi surface near node (0), accompanied by arc due to lifetime effects...
TiO2/reduced graphene oxide (rGO) nanocomposites with two different TiO2 particle sizes were synthesized by a facile hydrothermal method using source materials of Ti: tetrabutyl titanate (TBT) and commercial powder (P25). For respective series the same materials, we investigated additions that optimized nonlinear optical properties (NLO) limiting (OL) performances, explored relationships between structural diversity performance. Several characterization techniques, including X-ray...
The SQUID microscope is the most suitable instrument for imaging magnetic fields above sample surfaces if one mainly interested in field sensitivity. In this paper, both moment sensitivity and spatial resolution of are analysed with a simple point model. result shows that ratio sensor size to sensor–sample distance effectively influences resolution. comparison some experimental results images room temperature samples from our high-Tc an unshielded environment, brief discussion further...

Abstract In this paper, ZnO‐containing coatings were prepared on the surface of AZ31B magnesium alloy by a simple one‐step micro‐arc oxidation method using zinc gluconate as source. The microstructure, elemental distribution, phase composition and chemical analyzed scanning electron microscopy (SEM), energy spectrometry (EDS), X‐ray diffractometry (XRD) photoelectron spectroscopy (XPS), potentiodynamic polarization tests electrochemical impedance carried out in simulated body fluids to study...
A high-Tc SQUID-based non-destructive evaluation (NDE) system has been set up in our laboratory. The SQUID was made on a 24° bicystal SrTiO3 substrate. novel quadruple excitation coil proposed for the first time and applied artificial holes aluminium multilayer structure noisy unshielded environment. experimental data shows that it good balance is very effective at detecting small hole defects.
