Abstract In this work, the effect of the molar ratio of (Ni2+ and Fe3+) on the properties of CdO–NiO–Fe2O3 nanocomposites was investigated. The synthesis of CdO–NiO–Fe2O3 nanocomposites was carried out by self-combustion. XRD, UV–Vis, PL an

In the present study, a novel choice of sheath materials for drawing long superconducting MgB2 wire by using the powder-in-tube technique (PIT) is reported. This would eliminate the need for an intermediate strain-relieving annealing process and woul

An approach for description of the photoinduced nonlinear optical effects in the superconducting MgB2:Cr2O3 nanocrystalline film is proposed. It includes the molecular dynamics step-by-step optimization of the two separate crystalline phases. The pri

We developed a novel yet commercially viable strategy of synthesizing superior high-TC superconducting composites by dispersing fully exfoliated carbon nanotubes (CNTs) uniformly throughout the grain of CNT-MgB2 composites. First, we optimized the am

Higher concentrations of ceramic fillers induce brittleness in the ceramic/polymer hybrids which restrict their applications to limited fields especially when such hybrids are prepared for their use as dielectrics. We have synthesized and characteriz

A comprehensive study of the effects of structural imperfections in MgB2 superconducting wire has been conducted. As the sintering temperature becomes lower, the structural imperfections of the MgB2 material are increased, as reflected by detailed X-

In this work, we comparatively investigated two MgB2 films: one (F1) was typically fabricated using the PLD method, while the other (F2) was fabricated using the same method but on top of a 100-nm-thick CrO2 layer. Both films had a thickness of 300 n

A MgB2 film was deposited on an Al2O3 substrate (1102) using pulsed laser deposition (PLD) and in situ annealing at 700 °C for 30 min. The thickness of the film was 600 nm. The film was investigated using a PPMS system from Quantum Design. The film
