Introduction For the last decades there are a number of research teams who have been trying to develop biocompatible materials with unique properties for applications in a variety of biomaterial fields.
Co-precipitation and sol-gel method are generally preferred because they offer several advantages including the control of crystallinity, grain/crystal size, shape, morphology, stoichiometry, and interfacial properties to achieve good homogeneity [5], what is very important for ceramic materials designed to be utilized in orthopedic and dental applications.

One of the most salient microstructural characteristics is that there are lots of plate-like Ti3AlC2 grains consisted of a number of thin slices.

The increased cation vacancy concentration at the interface of the dispersoid and the grains of the host matrices led to highly conducting interfacial layer and increased the lattice defect.
This could be due to increased number of cation vacancies in the space charge region resulting in less energy required for anion mobility [18].

The grains are uniformly distributed and well dispersive when using MSC method (Fig. 2a), but not uniformly distributed and badly agglomerated when using CSC method (Fig. 2b).

Ultrasonic-assisted extraction and antioxidant activities of polysaccharides from Radix Astragali Wu Ming1,2,a, Ma Chuanfu3,b, Kan Junman1,c and Guo Liquan1,2,d * 1Key Laboratory of Grain and Oil Processing of Jilin Province, Jilin Business and Technology College, Changchun 130062, China 2Northeast Normal University, Changchun 130024, China 3Changchun Employment Training Center.
A number of bioactive components from Radix Astragali have been reported, including saponins, flavone and polysaccharides [3].

Namely, when the tip of a propagating crack meets a coating element (e.g. grain) with toughness exceeding the energy release rate (ERR) available, the crack becomes arrested.
Clearly, the number of such arrest events and thus the extent of quasi-stable crack growth depends on the ERR and the scatter of coating toughness.

Over the past few decades, a considerable number of studies have been conducted on the effects of industrial by-products, such as fly ash, silica fume, and ground granulated blastfurnace slag, on the mechanical properties and durability of the cementitious composites and the usage of those by-products in composites had a great influence on improvement its performances.
In conclusion, the inclusion of 10% SBA with the grain sizes capable of passing through a #325 sieve (45 μm) in composites had a better benefit on compressive strength.

Zea mays straws are the inner part of the seeds, grains, of the zea mays plant.
The numbers of Zea mays producing countries (Thailand, Nigeria, and India) are currently conducting research on industrial uses of zea mays straw.

Recently, the DSC model has been published in a number of papers [3-7].
The relative densities, Dr, of standard Ottawa sand (mean grain size D50 = 0.6 mm) specimens are 20% and 90% to analyze the responses of loose and dense sand specimens under triaxial compression test.
