As doing so, the demands for nano- particles are not only to maintain their outstanding special magnetic properties, but also to strengthen their biological compatibility, mechanic and chemical stability or other properties [5-7].
So, factors effecting hydrolyzation of TEOS include temperature, concentrations of water and ammonia.
But the hysteresis loops of samples that have been coated are weaker than that of Fe3O4, revealing that the coated layers affected the magnetic properties of SiO2@Fe3O4 micro-spheres.
With nonmagnetic SiO2 covered on Fe3O4, the magnetic properties of SiO2@Fe3O4 micro-spheres declined.
(3) Rotate speed almost had no influence on magnetic properties

This process is influenced by the long time external disaster-causing factors, but also has its own structure of the mutation process.
If at all hazard factors, environmental factors influence the material field uniform, null zone group structure and geometrical properties of goaf surrounding rock system plays a main role in disaster.
In addition, taking into account the current commercial application of three-dimensional numerical simulation program, mechanical calculation model needs more memory, the software itself has more difficulties in calculation process.
Free area size10m× 10m, empty area center distance 15m, model size is 140m ×140m, grid is divided into140× 140, rock mechanical parameters are shown in table 2.
But affected by several science and technology limited, the full sense of the empty area agglomeration spatial structure effect still need to be further studied.

The mechanical properties of these materials are crucial to achieving the grasping function along with the mechanical structure of the prototype.
Additionally, processing surface electromyography (EMG) signals and integrating these factors with a linear neural network are essential for enhancing control and grip precision in prosthetic hands.Through applying pattern recognition techniques on EMG signals, researchers have successfully improved the dexterity and functionality of myoelectric control for prosthetic hands [33].
Materials and Methods Mechanical system.
The flexibility of TPU allowed for a reduction from 3 to 2 DOF without affecting the grip of the three proposed gestures.

Carbon nanotubes (CNTs) have attracted interest of the composite researchers because of its tribological and mechanical properties.
The properties of nano fluids (Table 2) are tested in Mettex lab, Chennai, India.
This mixture of lubricant has to be checked for various properties such as Flash point, Fire point, Pour point, Kinematic Viscosity, etc.
Table 3 shows four machining parameters as control factors and their levels.

In heat transfer characteristic, the transport properties of the heat transfer fluids such as thermal conductivity, heat transfer coefficient, viscosity, etc. determine the performance of the base fluids [2].
However, those sizes are considered ‘big enough’ for sedimentation to occur, which affect the flow properties of the fluid and not practical for heat transfer applications [3].
Nanofluids consist of a stable suspension containing either metallic or non-metallic compound, which can change the transport and thermal properties of the base fluid [1].
The preparation of nanofluids has been quite challenging since many factors need to be considered, including the particle size and shape, temperature of the fluid, clustering of the particles, dissociation of the surfactant, etc. [5].
However, the agglomeration of the particles affect the stability of the suspension.

Higher concentration of NaOH is of advantage to the mechanical property development of the fly ash based cementitious material [[] A.
In light of the former study, the activity of fly ash plays an important role in the reaction of AAFA and contributes to the final properties of the mortars [[] A.
Results and discussion Effect factors on the dissolving of active Si/Al Fig. 1. shows the variation of active Si/Al dissolving percentage from fly ash activated with different concentration of NaOH solutions.
SEM pictures of fly ash particles activated by NaOH solution Conclusions The dissolving percentage of active components from fly ash depends on the chemical and physical properties of the initial fly ash.
The factors effects on the potential reactivity of fly ash are the concentration of alkali activator, the content of the vitreous phase and the particle size distribution of the flay ash.

These features help us to use the polymer mechanical components under corrosive condition, non-oil-lubrication conditions and an anti-magnetic environments etc.
In mechanical engineering field, their tribological potentials are focused on.
Wear on the all-PEEK bearings was not affected from the rotation speed, and melting failure of the hybrid bearing was obtained.
However, if the bearing is rotated under unexpected conditions, μ is affected by some noise factors.
