It is very well known that hollow particles have low density, high surface area, and distinct
optical and mechanical properties [3].
However, the relations among the decomposition of iron acetylacetonate, process variables and powder properties still remain unsolved.
In CVC process, among various process variables affecting formation β-Fe2O3, the reaction temperature is considered as the most important process variable especially controlling phase evolution.
Finally, the properties of iron oxide nanoparticles investigated in this study and in the literature are summarized in Table 1.

Movement of soot particles are examined through the selection factors of particle's initial coordinate (r,Ɵ,z) and soot concentration level at different instant crack angle.
It has been used widely nowadays in automotive field since it has a better fuel efficiency property compared to gasoline engine but it has drawback such as the formation of soot and other pollutants [1].
It happens since interpolation technique computes its result which is affected by the parameter value on the previous time-step where RBF and trilinear interpolation takes on the different value on the related parameter.
By knowing the properties and movement tendency of soot particles, solution to minimize or even control the tendency of soot particles to stick on cylinder wall will have a higher successful probability.

Landscape Zone
Above high water level is landscape zone, of which the hydrodynamic characteristic is affected only by runoff erosions, instead of flows.
Ecological revetment must be fitted into culture and environment in the surroundings, with consideration to anti erosion properties of slope.
Submergence-resistance is not required in the zone, as such, strongly-rooted and inter-crossed herbs, shrubs and trees, which of good mechanical properties, large coverage and some ornamental value, are employed in the zone.
Landscape zone is affected only by runoff erosions, instead of flows.
Combined with ecological characteristics of revetment plants (flood and erosion resistance are fundamental factors), vegetations adapting to different protection area have been analyzed and discussed.

These components endowed COLLOSS® E with all the bone formation activities of osteoconductive, osteoinductive and osteogenic properties.
(b) Most mono-factors are only effective in very high concentrations.
Bioactivity.The ideal bone graft possesses the three properties of osteoconductivity, osteoinductivity, and osteogenicity [1].
Only autologous bone graft is qualified for all the three properties nowadays.
Although many factors have been verified to accelerate bone formation, how these factors do it and interact among them is still mysterious.

Beside the unavoidable poor corrosion properties, magnesium has a poor weldability as well.
Based on the joint properties an adhesive bonding of the parts is preferred.
Beside the thermo mechanical affected zone (TMAZ) borders the heat affected zone (HAZ).
These phases provide, due to their low ductility, an explanation for the lower mechanical properties of the joints.

The microstructured-layer in the middle of the model consisted of three phases of unique material properties: the fibre, the matrix and the fibre-matrix interface.
The material properties of the infinite elements were set to be the same as the EHM.
Material Properties and Simulation Conditions.
The material properties used in the FE analysis are given in Table 1 [7, 9, 17], and the cutting conditions are listed in Table 2.
It is clear that the frequency affects the fibre fracture significantly.

The structure and morphology properties of NiO/CNTs composites are characterized by several techniques.
Measurement of electrochemical properties.
Therefore, the most important factor affecting the coating of NiO is the mass ratio of CNTs versus NiO.
Cyclic voltammetry (CV) is employed to determine the electrochemical properties of the NiO/CNTs electrodes in 2 M KOH.
