XRD is useful for characterizing crystalline structure of carbon materials such as polycrystalline graphite structure; however, biomass semi-cokes are highly disordered carbonaceous materials that have a short-range order poly-crystalline structure [14].
The pore structure parameters of SC and AC are listed in Table 1.
There are complex physical and chemistry reactions when the flue gas go through the fixed-bed in the surface of SC and AC.
The pore-structures of AC and SC can catch the NO molecule and Hg atom from flue gas.

Thermolysis of the precursor in oleylamine at 240 °C gave the nanoparticles most of them are monodispersed spherical shape, few having mono and dipod structures.
TEM images confirm the structures.
CdS with hexagonal structure is highly favourable for solar cell application as a window layer because of it suitable bandgap and stability [6,7].
TEM images confirm the structures.

Its super-insulation property, due to slim nano-porous structure, makes such material have great application prospects[1-5].
Study on five kinds of drying temperature affect on the performance of the structure and properties of aerogels.

Morphological analysis revealed the formation of spherical structures composed of numerous hair-like structures arranged in an urchin-like fashion.
Fig. 2 shows the SEM images of urchin-like CuO nanostructures.Spherical structures comprised of numerous nanowires were produced, preferentially arranged to resemble an urchin structure.
Hence, an urchin-like structure is achieved.
The SEM images revealed the formation of spherical structures composed of numerous hair-like structures arranged in an urchin-like fashion.

The phase, composition, structure, and morphology of the as-obtained samples were verified by XRD, XPS, SEM and TEM measurements.
Owing to the great influence of particle size, dispersivity of nanoparticles, morphology, powder surface chemistry and preparation methods on the properties of powder particles [17], the particle size of V2O3 nanopowder with good purity and dispersibility in this paper is 20 ~ 70 nm.
During the heat treatment of precursor powder, the autogenic gas CO, CO2 overflowed from the powder structure could destroy the original structure and refine the grains by reducing the agglomeration between ions and inhibiting the growth of grain.

Magnetic microspheres made from the distribution of structural materials can be categorized into the shell-core structure, core-shell structure, and shell-core-shell structure.
In the shell-core or core-shell structure microspheres, the core or shell can be a polymer material.
In the shell-core-shell structure, the middle core is made of magnetic materials and the shell is polymer materials.
Among them, the core-shell structure of magnetic polymer microspheres has received considerable attention and is one of the most widely used structures [4-6].
