The vapor of the agent then affects the lightpath of the bonding elements.
The silica filler is usually adding to the epoxy, one of the thermosetting adhesions, for the lower properties of the curing shrinkage and the CTE [16].
Besides, the FBGs is a reliable and accurate sensor for measuring of the strain and temperature subjected to the central wavelength of FBGs with the positive linear proportional to the previous two factors.
This evidence enhances that the bonding adhesion has the curing shrinkage affecting the misalignment of the light path of optical elements.
By the optical fiber properties and the decreased stress in Fig. 6, the curing shrinkage of the filler/epoxy adhesion is about 0.05% at 60 oC.

Atomic scale modelling of materials: a prerequisite for any multi-scale approach to structural and dynamical properties Masahiko Matsubara1a, Massimo Celino2b, Philip S.
Introduction A growing research strategy in the area of condensed matter computer simulation is to model the properties of a given system by using a multiple step approach.
As a first step (part (a)), we shall recall our main results on the structural and dynamical properties of neutral Si-doped heterofullerenes.
Changes in the electronic properties of fullerenes caused by doping have the effect of creating new reactive sites.

The uniqueness and impact of this area is that it does not rely on specific material properties to achieve control of light; rather it relies on the engineering of subwavelength scale nano-structures and arrangements that will induce a strong light-matter interaction [1-2].
Such designs have been reported [5] to decrease radiative losses, leading to a cavity with higher Q-factor and improved transmission of the cavity mode.
The resonant mode quality factors (Q) are obtained from the fast-harmonic analysis which yields good accuracy results and high spatial resolutions with relatively short convergences temporal iterations needed.
The calculated Q factors of the cavity design is approximately Q = 2.8×104.
To ensure that the large area region of the doubly perturbative tip actuating mechanism does not affect the nanocavity, the length was chosen to be 1.5µm before linearly tapering the probe structure to a width of 2µm.

As a result, size of grains was a predominant factor for high resistance at low applied load and/or sliding velocity, while hardness at higher applied load or velocity.
Mechanical milling(MM) and alloying(MA) were carried out for 12 hrs in 320 rpm using 304 stainless steel balls(Φ 6.35 mm) and container coated with pure Al.
Results and Discussion Microstructures and mechanical properties.
However, wear mechanisms, such as adhesion and abrasion etc, is known well to be obviously affected by microstructures.
Thus, in this work, wear tests were performed in more detail varying the factors of sliding distance, velocity and applied load to investigate the effects of grain size.

Some properties of the samples were evaluated in this paper.
In particular, P/M Al alloys can be commercially used as candidate materials for automobiles, electronics and aerospace applications because of their lightness and good mechanical properties [2].
Among them Al-Si alloys are the most interest materials for high strength structural components because they have low coefficient of thermal expansion (CTE) as well as high wear resistance and mechanical properties [3, 4].
The mechanical properties of Al-Si alloys are dependent on the volume fraction and size of the eutectic Si particles.
Dynamic pressure in the gas atomization process was an important factor to control the powder size.

ZnO thin film, as a promising piezoelectric material, possesses unique electrical, acoustical, and optical properties.
The electronic and acoustic properties of the SAWF were studied by radio-frequency network analyzer.
A rough surface would affect the polarization properties of the film and reduce the piezoelectric effect, then augment the insertion loss greatly [9].
When operating high frequency SAW devices, it requires better mechanical properties of piezoelectric film to endure the stress of electrodes engendered from SAW spreading and have good adhesion to the substrates.
The mechanical properties of the ZnO films were investigated by means of nanoindentation measurement and scratch testing on a MTS XP nanodenter system, equipped with the continuous stiffness measurement (CSM) option.
