X-ray photoelectron spectroscopy (XPS, Kratos XSAM800) spectra was obtained by using Al Ka radiation (12 kV and 15 mA) as an excitation sourceAll samples were analyzed by gas chromatography (Agilent GC-6890) equipped with a flame ionization detector and a SE-30 supelco column (30 m×0.25 mm, 0.25-um film).

Pietrowski et al.[14] proposed that the hydrogen bonds between o-CAN and water in the solvent played a key role in improving the catalytic hydrogenation rate.

It has been widely researched in organic electrotransporting electroluminescent(EL) materials which are small molecule and polymer [1-6].
Some people have studied for it in photochromic materials, Pu et al. had reported the photochromic of compounds containing the pyrazole ring and pointed out that these compounds have strong fluorescence [10].
Gupta et al. had discussed the fluorescence property of complex compound composed of pyrazole derivatives and metal ion [11].

In addition, many phases which are possible to be contrast and morphological distinguish were observed in Al matrix.
This is a major effect on the matrix strengthening resulting from the solution of Cu atoms into the Al matrix.

As far as aluminum T-stub connections is concerned, De Matteis et al. [8] investigated for the first time the possibility of extending the provisions given by Eurocode 3 for T-stub also to aluminum joints.
Indeed, another numerical study, carried out more recently by De Matteis et al. [13], put into evidence some shortages related to the above formulations.
Experimental and numerical studies on a welded specimens made of the EN AW 6082-T6 alloy were carried out and the elastic strength Fcwt,el, expressed in Eq. 4 as a function of the effective length beff,el given in Eq. 5, was provided.
The above equation results by the assumption of a linear distribution of the tensile stresses, through the column web, characterized by a 1.7:1 slope that is lower than the one generally assumed for steel (2.5:1), according to the formulation provided by Eurocode 3, which derives from the studies carried out by Aribert et al. in 1981 [7].

Tran et al., for an example, found that brookite possessed high photocatalytic capacities for the degradation of different hazardous compounds under sunlight equivalent conditions [2].
Yu et al. [5] studied the effect of acidic and basic hydrolysis on the microstructures of titania.
However, Zheng et al [6] synthesized brookite nanocrystallites using Ti(SO4)2 or TiCl4 as the precursor with hydrothermal treatment method by controlling pH values and the reaction temperature.

As explained by El Fgaier et al [10] an increase of the water content leads to higher amount of water in the sample’s porosities, replacing air.
The influence of the vegetable aggregates on the sorption/desorption properties is not clearly significant as shown by Belayachi et al [11] for different straws in straw concretes.
El Fgaier et al study [10] showed that mass moisture content of unfired clay bricks could reached 3.5% at 95%HR.

The CO2-blasting is demonstrable suitable for cleaning processes as well and therefore a simultaneous deburring and cleaning can take place (Krieg, 2007; Elbing, 2015).
The automatization and integration in a machining center result in a reduction of lead times and an increase in efficiency (Uhlmann, et al., 2010).
As mentioned in the introduction before, CO2 blasting technologies are already being used successfully for deburring plastic components (Uhlmann, et al., 2010).
