Microstructural properties

To elucidate these issues, a detailed study of the microstructure of amorphous V2O5 under pressure was needed. The spatial distributions of atoms, the link distributions and the geometrical distributions of the free volumes need to be fully investigated. The distribution of free volume in the amorphous V2O5 network also needs to be visualized. These are the main contents in this paper.

In this report, SYGO:Eu3+ red phosphor have been successfully synthesized by sol-gel method. The X-ray diffraction results show that the sample has a cubic crystal structure, belonging to the space group Ia3d (230) without any doping. Scanning electron microscopy (FE-SEM) combined with EDS was performed to determine the microstructure and elemental composition of the fabricated phosphor.

This textbook represents an attempt to present a relatively brief overview of Materials Science, the anticipated readership being students of structural and mechanical engineering. It is in two sections – the first characterising engineering materials, the second considering structure–property relationships. Emphasis is thus placed on the relationship between structure and properties of materials, starting with the concept of ‘structure’ at three levels - crystal structure, microstructure, and molecular structure.

The material’s structure was analyzed through X-ray diffraction and scanning electron microscopy. The fabricated materials consist of NiTiO3 with a rhombohedral phase structure and CoFe2O4 with a cubic structure. The effect of sintering temperature and dwell time on the phase, microstructure, and ferroelectric properties of the ceramics was examined.

The obtained results showed that the coating at the spray current of 300 A, the air pressure of 5.5 bar and the stand-off distance of 162.8 mm has the lowest porosity and highest microhardness. In addition, this coating also has better adhesion to the steel substrate and wear resistance than other coatings. Moreover, X–ray phase analysis showed that the following phases are created on the surface of the Al-Mg coatings: Al, Al2MgO4 and Al3Mg2.

Ebook "Crystallization of nanoscaled colloids" deals with the processes that create ordered assemblies from disordered nanoparticles. Ordered packings of nanoscale particles can exhibit unusual properties. This work investigates the self-assembly of such particles, a process widely employed for the generation of ordered structures, but not yet well understood. In situ methods are used to observe the assembly of sub-micron polymer lattices and sub-10 nm gold particles into crystalline monolayers and aggregates.

Ebook "Electron microscopy in heterogeneous catalysis (Series in Microscopy in materials science)" addresses a number of issues that are fundamental to the understanding of heterogeneous catalysis by oxides and supported metals. The properties of a catalyst are governed by its microstructure and chemistry on an atomic scale, and electron microscopy methods are essential to directly analyze these properties.
