In this paper, an electrospraying technique was applied to prepare polycaprolactone (PCL) polymer particles with a different microstructure. The PCL particles can be controlled to have a porous microstructure by tailoring the evaporation of solvents during the electrospraying process. The effect of various concentrations on the morphology and microstructure of PCL particles was investigated. Th...

The term microstructure refers to the complete internal structure of a material on the micro, nano and atomic scales. On one hand, it records the entire history of a material’s processing and structuring (casting, forming, heat treatments, but also crystal growth, etc.) through its phase composition, defect structure and morphology. On the other hand, all properties (stiffness, formability, con...

We use geometrical arguments based on grain boundary symmetries to introduce crystalline interfacial energies for interfaces in polycrystalline thin lms with a cubic lattice. These crystalline energies are incorporated into a multi{phase eld model. Our aim is to apply the multi{phase eld method to describe the evolution of faceted grain boundary triple junctions in epitaxially growing microstru...

In this paper, the effects of Nb addition (5-20 wt %) on the microstructure, mechanical properties, corrosion behavior, and cytotoxicity of Ti-Nb alloys were investigated with the aim of understanding the relationship between phase/microstructure and various properties of Ti-xNb alloys. Phase/microstructure was analyzed using X-ray diffraction (XRD), SEM, and TEM. The results indicated that the...

PURPOSE The purpose of this study is to evaluate the feasibility of phase contrast X-ray microtomography and microradiography, using a polychromatic synchrotron X-ray, for analysis of the mouse lung microstructure. MATERIALS AND METHODS Normal mice were used for experiments. Some of the mouse lungs were prepared by the lung fixation-inflation method. The resulting sponge-like inflated lung sa...

Ferroelectric perovskites are used in various transducer, memory and optical applications due to their attractive electromechanical and optical properties. In these applications, ferroelectrics often have complex geometries and function under complex electro-mechanical loadings. Phase-field models are typically used to predict the formation of microstructural patterns and subsequent evolution f...
