TL;DR: In this paper, the growth mechanism of Na0.44MnO2 nanorods via solid state synthesis and their physical properties were investigated by X-ray diffraction (XRD), scanning and tunneling electron microscopy (SEM and TEM), and energy-dispersive Xray (EDX) techniques.

TL;DR: In this article, the structural, electrical, thermal and magnetic properties of Pb-doped Ca 3 Co 4 O 9 in the range of 300-5 K were reported.

TL;DR: LiCo1−xBxO2 (x = 0, 0.125, 0., 0.25, 0,0.75 and 1) samples were synthesized via solid state reactions as mentioned in this paper, and the effective magnetic moments of the samples were calculated using Curie-Weiss law with temperature independent term.

Abstract: Eu–Ba–Cu–O composition was synthesized by solid state reaction technique. To determine optimum growth temperature, heat treatment was examined on the material at 880–1,100 °C. Microstructural evolution, phase formation and elemental distribution depending on heat treatments were examined by using X-ray diffraction, scanning electron microscope, energy dispersive X-ray spectroscope analysis. Optimum fabrication conditions were determined as 1,020 °C for 24 h under oxygen atmosphere and detailed characterization of corresponding compound was performed. The magnetization hysteresis loops are expounded to be the product of superconducting Eu-123 grains and magnetic Eu2+ ions. The peak effect on the magnetization curves was described by the extended critical state model. Scaling of the pinning force was found such that the peak position is proportional to the irreversibility field H irr and the maximum pinning force is proportional to H irr 2 .

TL;DR: In this paper, a new series of ringexpanded six-and seven-membered N-heterocyclic carbene precursors and their transition metal complexes were synthesized.
