TL;DR: In this article, a simple electrospinning technique using ferric nitrate (Fe(NO)3·9H2O) and polyvinylpyrrolidone (PVP) as precursors was successfully synthesized by a simple hollow cage-like α-Fe2O3 microspheres with an average diameter of 500 nm and a shell thickness of 60 nm.
Abstract: Hollow cage-like α-Fe2O3 microspheres with an average diameter of 500 nm and a shell thickness of 60 nm were successfully synthesized by a simple electrospinning technique using ferric nitrate (Fe(NO)3·9H2O) and polyvinylpyrrolidone (PVP) as precursors. Fe(NO)3/PVP composite microspheres were calcined at high temperature to form an interconnected 3D hollow cage-like α-Fe2O3 structure. X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), high-resolution transmission electron microscopy (HRTEM), and magnetic measurements were used to characterize the morphology, structure, and magnetic properties of α-Fe2O3 microspheres. Based on the characterization results, a formation mechanism for electrospun hollow cage-like α-Fe2O3 microspheres was proposed. We also found that morphology-preserved conversion from α-Fe2O3 to magnetic Fe can be achieved during reduction reactions in H2/Ar. The magnetic property investigation showed that the as-prepared hollow Fe nanostructures exhibit a ferromagnetic behavior and possess high saturation magnetization (Ms).

TL;DR: In this paper, the authors present a study of local variations in the texture (microtexture) as well as grain boundary or mesotexture associated with copper wire and its implications for micromechanical inhomogeneity within a sample volume.
Abstract: In many processing operations, it is critical to know the relationship between the resultant sample geometry and the distribution of crystallographic or grain orientations within the polycrystalline aggregates. The spatial variations in crystallographic texture associated with different parts of the sample geometry can influence differences in the plastic response within different regions of a sample. In this paper we present a study of such local variations in the texture (microtexture) as well as grain boundary or mesotexture associated with copper wire and its implications for micromechanical inhomogeneity within a sample volume. The unique experimental and analytical aspects of such microtexture characterization are discussed along with the issues of grain boundary structural parameters and its role in microtexture and anisotropy. The presence of differences in twin frequency in different regions of the sample is suggested as a possible source of strength anisotropy.

TL;DR: The microstructure, microhardness, texture and corrosion resistance of cold-swaged and coldwiredrawn copper rods were evaluated in this article, where the copper grains in both cold-worked rods presented a preferential orientation in the [1/1/0] crystallographic direction but this trend was more pronounced for swaged rods.
