Maheshwari et al. [18,19] reported that the release of tetracycline from 20%w/w pluronic gel was decreased with the amount of Aerosil, indicated that structure of gel functioned as barrier to drug release and it suggested that Aerosil enhanced the dehydration of of PPO block of the micelle thus micelles could not separate easily from each other, which account for the rigidity and slow dissolution of these gels.

Song et al. [25] elaborated the key points for the corrosion of Mg alloys includes: a partially protective film covers the surface of Mg; hydrogen evolution is intimately associated with the dissolution of Mg; Mg has a negative free-corrosion potential with a slightly more negative pitting potential and the chance development of areas of localized corrosion leads to the undermining and falling out of particles of Mg.

In addition, based on research conducted by Iovane et al., the use of membrane purification technology using polymer membranes has also shown satisfactory results, which can increase the concentration of methane gas by up to 80% and can remove carbon dioxide concentrations by up to 60% [7].
According to Yakout and El-Deen, the pore structure formed comes from the evaporation and dissolution of non-carbon compounds contained in the raw material caused by the pyrolysis process or physical activation [12].

Colombié et al. reported using a batch technique on mixing anionic-nonionic surfactant in the emulsion polymerization of Styrene, resulting in the more significant effect of particle nucleation and faster rate of polymerization as 17 times more particles were initially created [12].
This result was confirmed by Erkal et al., which stated that the formed polymer's solid content would be terminated after the propagation reaction time at 5 – 15 minutes.
Results of pH for cationic surfactant of PVAc From the set of surfactant used, the pH measured on amphoteric surfactant resulting in stable latex after the PVAc formed at 90 minutes, this result on amphoteric surfactant is confirmed by a report from Abele et al. is also not clear why in use of amphoteric surfactant resulting in stable latex pH during the reaction.

Umbrello et al. built mathematical equations through the construction of artificial neural network method and the technology of data management chose ppropriate experimental data, who predicted the relationship between cutting parameters and the residual stress, and established the analysis model of cutting parameters and residual stress[6].

In the first method according to a proposal by Kurz et al. [5-9] GaSb nanostructures are realized through self-organization during mask-less dry-etching.
Many investigationson this material system have been done f.e. by Forchel et al. [15-17] and Bimberg et al. [18].
And Huffaker et al. achieved samples with a dot density up to 3 ∙ 1010 cm-2 by variation of the Sb/Ga flux ratio (V/III ratio) [19,20].
