Hydroxyapatite is a biocompatible ceramic and reinforcement for bone implantations. SEVA/HAP composite content HAP filler with difference particle sizes were designed. Mechanical tests like tensile modulus, UTS, strain at break and biodegradation were investigated. Results illustrated much increase tensile modulus of composites content HAP nano powders ratio to micro powders. Also UTS analysis ...

Several polypropylene composites with varying amounts of inorganic particles of different sizes were investigated. In dependence of the particle sizes four different tomographic methods were used to describe the morphology 3-dimensionally. For particle sizes of several micrometers sub-μm X-ray tomography and light optical tomography are suitable whereas for smaller particle sizes scanning elect...

With the increase of particulate pollution in atmosphere, it becomes extremely significant to understand overall distribution characteristics particulates and their adsorption toxic gases for source analysis precise controlling atmospheric matters. The fractal theory was adopted analyze particle sizes Xi?an city, China. Results showed dimension matters ranged from 4.32-4.83, with an average 4.5...

In order to observe the impact of different water compositions on sludge dewaterability, assessments of floc sizes using a particle size analyzer and of sludge dewaterability based on the capillary suction time (CST) test were carried out. Synthetic raw water had small floc sizes, and synthetic domestic wastewater had both larger median floc sizes and a better correlation between sludge dewater...
