alumina nanomaterials were synthesized via a solution combustion technique using tris-(acetylacetonato) aluminum(iii) complex (1) and tris-(2-formylphenolate) aluminum(iii) complex (2) at 600, and 1000 °c for 3h. the obtained data showed that the procedure without using fuel resulted in a better phase and morphology. to investigate the phase formation, powder x-ray diffraction technique was use...

Metal matrix composites have been widely studied in terms of abrasion resistance, but a particular material system may behave differently as particle size, morphology, composition, and distribution of the hardening phase varies. The purpose of this thesis was to understand the mechanical and microstructural effects of combining titanium carbide with 431 series stainless steel to create a unique...

pure barium zirconate nanopowders were successfully prepared in wet-chemistry synthesismethod, using barium stearate and tetra-n-butyl zirconate as ba, zr sources and stearic acid ascomplexing reagent. the gel was calcined at 800 and 900 °c in air. results of thermal analysisare given, including both dtg and tg. fourier transform infrared spectrometry (ftir), x-raydiffraction (xrd), transmissio...

The commercial profile of the Amoco CD MgCl2 supported polypropylene catalyst is presented. The development, the unique method of preparation/production, with emphasis on particle morphology, and the parameters affecting particle size (PS), particle size distribution (PSD), and particle shape are discussed in detail. The outstanding performance of the catalyst, tailoredmade for the Amoco-Chisso...

INTRODUCTION Overlooked polymethylmethacrylate after unicondylar knee arthroplasty can be a potential problem, since this might influence the generated wear particle size and morphology. The aim of this study was the analysis of polyethylene wear in a knee wear simulator for changes in size, morphology, and particle number after the addition of third-bodies. MATERIAL AND METHODS Fixed bearing...

Films cast from multiphase polymer particles have the potential to combine the properties of their components synergistically. The properties of the film depend on the hybrid polymer architecture and the film morphology. However, how the polymer microstructure and particle morphology are transformed during film formation to determine the film morphology is not well understood. Here, using water...
