Composite characteristics morphological examinations

HAPEX, a bone analogue material, with similar properties to cortical bone, was added to a HDPE matrix in different volumes (20% and 40%) to produce composite materials [271]. Confocal laser scanning microscopy (CLSM) was then used to examine cell morphology on HAPEX and the surface characteristics produced by different machining protocols. 

This chapter describes the preparation and examination of ceramic matrix composites realized by the addition of different carbon polymorphs (carbon black nanograins, graphite micrograins, carbon fibers and carbon nanotubes) to silicon nitride matrices. In the following sections, structural, morphological and mechanical characteristics of carbon-containing silicon nitride ceramics are presented. 

We have demonstrated the effects of temperature fields on deposit characteristics. The temperature distribution of field B is more uniform than that of field A. The temperature fields have important effect on the morphologies, phases, microstructute and compositions of deposits. Under the temperature field A, the morphologies were crystalline-like, the boron concentration was 87.11 at.%, the phase of deposit was B13C2 according to XRD and TEM examinations. Under the temperature field B, the morphologies were cauliflower-like, the boron concentration was 75.34 at.%, the phase of deposit was amorphous... 

This chapter reviews the general context of starch as a material. After a survey of the major sources of starch and their characteristic compositions in terms of amylase and amylopectin, the morphology of the granules and the techniques applied to disrupt them are critically examined. The use of starch for the production of polymeric materials covers the bulk of the chapter, including the major aspect of starch plasticization, the preparation and assessment of blends, the processing of thermoplastic starch (TPS), the problems associated with its degradation and the preparation of TPS composites and nanocomposites. The present and perspective applications of these biodegradable materials and the problems associated with their moisture sensitivity conclude this manuscript. 

The performance of clay-based construction products, e.g., bricks and roofing tiles, can be monitored using thermal methods. The types of raw materials, viz., clay and accessory minerals, and their reactions that occur during the firing process and the durability of clay products can be examined through the application of DTA, TG, TMA, and dilatometric methods. This is particularly important for quality control as physical and chemical behaviors are dependent on the raw material characteristics, e.g., composition, particle size, and morphology.
