Since both shows promising properties hence the combinations of both filler is expected to exhibit desirable properties of the individual constituents just like Ko et al. [3] have proven in their work.
El-Sabbagh et al. [11] also stated similar results.
Sajjayanukul et al. [12] explained that the due to the dilution effect caused the amount of deformable rubber is diluted by the underfomable rigid particles of carbon black.
Ismail et al. [13] stated that fast and unstable propagation is believed to occur leading to catastrophic failure.

Lu and Wu et al studied the synthesis of Mg-Al hydrotalcite and used it as the catalyst of transesterification.
Serio et al used PURAL® MG76 hydrotalcite as catalyst to produce biodiesel.
Compared with the life of single Mg-Al hydrotalcite catalyst (the activity decreased of 38% in 50 h [27]), Mg-Al hydrotalcite /g-Al2O3 can be more useful in industry.

An Analysis of Mechanical Properties of the Developed Al/SiC-MMC’s.

The heat treatment process causes further increment in Eu and the value lies between 0.409 to 0.424 eV which is consistent with the results reported by El-Mallawany et al. [11].
The position of absorption edge depends on the oxygen bond strength in the glass formation network need to be considered as discussed by Amjad et al. [9].

Various experimental techniques such as electroluminescence (EL), synchrotron white beam x-ray topography (SWBXT), cathodoluminescence (CL), and electron-beam-induced current (EBIC) have been applied to investigate the SFs in degraded diodes [1].
Among these techniques, EL imaging is one of the most effective tools to visualize the dislocation motion in situ.
However, an excitation region is restricted in the junction region and it is not easy to excite any region of interest by the EL method.
A 10 µm-thick epilayer was deposited on the substrate by chemical vapor deposition (CVD) without using any additional low basal plane dislocation (BPD) growth process as reported by Sumakeris et al [2].

Iron hook is widely used to strengthen Chinese tenon-mortise joint to enhance its strength in southern China districts.To find strengthening effects of this material, by shaking table tests dynamic characters as well as seismic responses of a 1:8 scale wooden frame model were studied under conditions that each of its tenon-mortise joint was/was not strengthened by iron hook.By white noise excitation,values of basic frequency of both unstrengthened and iron hook strengthened models were obtained;by inputing El-centro earthquake waves of different peak acceleration values, displacement and acceleration responses of the models were obtained,dynamic magnification factors for tenon-mortise joints as well as models were discussed.Results show that after each tenon-mortise joint of the model is strengthened by iron hook,its basic frequency increases,its displacement and acceleration responses under earthquakes decrease.However as iron hook can only restrict tenon from pulling out of mortise but
Under earthquakes on one hand friction between tenon and mortise during rotation course of tenon-mortise joint produces energy dissipation,on the other hand tenon is pulled out of mortise (see Fig.1a).Too large rotation angle of the joint may make tenon disengage from mortise,which will lead to instability of the whole structure.Thus tenon-mortise joint has to be strengthened on time for protection of Chinese ancient building.In previous works Chang et al.[1-2] studied different damage types of tenon-mortise joint by experiment and proposed damage estimation as well as strengthening methods for tenon-mortise joint; Xie et al. [3] and Yu et al. [4] studied aseismic behaviors of tenon-mortise joint by CFRP sheets and iron band by experiments on a plane wooden frame; Liao [5] studied strengthening methods for tenon-mortise joint in Tai Wan district by experiments and proposed available suggestions.
(a) iron hook (b) strengthening location Fig.3 Iron hook for strengthening tenon-mortise joint To get values of displacement as well as acceleration of model under earthquake,node S1 and S2 are selected,on which draw-wire displacement sensor and accelerometer are set;node S3 is selected to set accelerometer,as shown in Fig.2.During experiment firstly white noise of PGA=0.05g is excited to the model to get its basic frequency and damping ratio,then El-centro earthquake waves of PGA=0.1g,0.2g and 0.3g are applied to the model in east-west direction to study seismic response curves of the selected nodes.Here “PGA” means peak ground acceleration, “g” means gravity acceleration,1g=9.8(m∙s-2).
