Flux pinning and phase separation in oxygen rich La2-xSrxCuO4+y system
, 2008 We have studied the magnetic characteristics of a series of super-oxygenated La2-xSrxCuO4+y samples. As shown in previous work, these samples spontaneously phase separate into an oxygen rich superconducting phase with a TC near 40 K and an oxygen poor ...

InfoMat, EarlyView.MXenes are considered highly promising next‐generation energy storage materials due to their exceptional physicochemical and electrochemical properties, yet their electrochemical performance is severely hindered by nanosheet restacking. Constructing in‐plane pores directly on MXene nanosheets has emerged as an effective strategy to accelerate ion ...

Journal of Quaternary Science, EarlyView.Abstract The Burren uplands in western Ireland form one of the most extensive and best‐preserved examples of glacio‐karst in Europe. Subsumed by the Irish ice sheet during the Late Pleistocene, granite erratic boulders and in situ silica veins in the limestone bedrock provide a rare opportunity to reconstruct the timing and rate of deglaciation ...

The Different Practical Application of Niobium Carbide Coatings Elaborated by CVD Process
The Annals of “Dunarea de Jos” University of Galati. Fascicle IX, Metallurgy and Materials Science, 2016 In this paper, the different application of niobium carbide coatings onto hard carbide substrate was investigated using scanning electron microscope (SEM), Xray diffractometer (XRD) and micro-hardness.

Compatibility of refractory materials for nuclear reactor poison control systems [PDF]
Metal-clad poison rods have been considered for the control system of an advanced space power reactor concept studied at the NASA Lewis Research Center. Such control rods may be required to operate at temperatures of about 140O C.

Superconductivity in the $\eta$-carbide-type oxides Zr4Rh2Ox
, 2019 We report on the synthesis and the superconductivity of Zr$_4$Rh$_2$O$_{x}$ ($x$ = 0.4, 0.5, 0.6, 0.7, 1.0). These compounds crystallize in the $\eta$-carbide structure, which is a filled version of the complex intermetallic Ti$_2$Ni structure.

Failure Investigation of Alloy 625 Sockolets After Prolonged Service in an Ammonia Cracker Unit
Materials and Corrosion, EarlyView.The failure of the sockolets was caused by intergranular cracking and fracture. The thick and highly brittle nitrided layer formed intergranular surface cracks, which propagated along grain boundaries into the base alloy substrate due to the presence of brittle Cr‐rich carbides. ABSTRACT Several sockolets of Alloy 625 operating at 540°C in contact with

Mechanical performance of alumina reinforced with NbC, TiC and WC
Materials Research, 2012 The incorporation of refractory hard particles in Al2O3-based composites may inhibit grain growth of the matrix, which could significantly contribute to mechanical performance of the composite.
