“…Sun et al [219] reported 2D IR of hydrothermally synthesized zinc organo phosphonate complex under thermal perturbation. 2D IR of hydrothermally synthesized zinc (II) metal phosphonate complex under thermal perturbation was reported by Zhang et al [220]. Zhao et al [221] used 2D IR for temperature and magnetic field induced structural variations of hydrothermally synthesized rareearth complexes with 3-methylbenzoic acid.…”

“…The partial substitution in the parent YBCO structure has been investigated intensively in an attempt to clarify or improve the superconducting behavior of this type of superconductors [2] [3] [4] [5] [6]. Transition metal oxide materials with perovskite-like structures have been extensively investigated in the recent decades for their novel properties such as superconductivity, ferroelectricity, and colossal magnetoresistance [7].…”

The work reported in this paper aims at a better understanding of the magnetic doping effects on the structural and electrical properties for a series of YBa 2 (Cu 1−x Co x ) 3 O 7−δ ceramics. The Co doped YBa 2 Cu 3 O 7−δ are (YBCO) prepared by conventional solid state reaction method and characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM), differential thermal analysis (DTA) and resistivity measurements. The crystal lattice parameters are found to change due to the cobalt doping and tendency to a structure phase transition from orthorhombic to tetragonal, which is confirmed by the decrease of the degree of orthorhombicity. The morphology examination with SEM revealed gradual increases of grain size with x = 0.02 Co, a high porosity is observed in the doped samples compared to the pure one. The decomposition temperature of YBCO is pushed from temperatures above 975˚C to lower temperatures of 945˚C. The resistivity measurements of doped samples with x = 0.04 and 0.06; shows a deviation in from T-linear behavior due to the opening of a pseudogap.

“…In Akerlof's famous Lemon Problem, the customers have no means to assertain the quality of products, which leads to a no-trade paradox [1]. When the customers are better equipped, optimal quality emerges [2,3,4]. One of the main issues is to understand under which conditions a manufacturer should diversify his production.…”
